The plate and edge channel press is an ooze treatment framework for muck treatment gear, is a typical hardware in the ooze treatment process, this article for the plate and edge channel press to do a definite presentation and reply, assuming you have inquiries concerning the plate and edge channel press can be to the Dirt Top people group trade communication!
1、The rule of plate and edge channel press
The plate and edge channel press is made out of five significant parts: channel press plate, pressure driven framework, channel press outline, channel plate move framework and electrical framework. The guideline of the plate and edge channel press is moderately basic, first and foremost, the water powered strain is applied to the plate and edge bunch, and the dregs enters from the center and is circulated between the channel materials. Because of the pressure of the plate and edge, the ooze can’t flood and under the high tension of the screw and stomach siphons, the water in the muck leaks out of the channel material and streams into the return pipe, while the mud cake is left in the depression. Subsequently the plate and edge dumps, the channel plates are pulled separated and the mud cake falls by gravity and is pulled away by a vehicle, so the channel press process is supposed to be the last interaction in the sewage treatment process. For subtleties of the rule see the video show.
The plate and edge channel press is appropriate for suspensions with a huge or almost incompressible channel buildup. Appropriate suspensions for the most part have a solids convergence of 10% or less and a working strain of 0.3 to 0.6 MPa, with exceptional ones up to 3 MPa or higher. The filtration region can be expanded or diminished relying upon the quantity of plates and casings utilized. The plate and casing are normally square, with an internal side length of 320 to 2000 mm, an edge thickness of 16 to 80 mm and a filtration area of 1 to 1200 m2. The plates and edges are squeezed with manual twisting, electric winding and water powered tension. The plates and edges are made of wood, cast iron, cast steel, tempered steel, polypropylene and elastic.
2、Safety activity safety measures
1、When the channel press works ordinarily, the administrator should not put his feet, hands or head into the channel plate of the channel press or notice the belt transport or the focal tank underneath from between the cuts of the channel plate that is pulled open. It is taboo to put apparatuses on the pulling snare outline and the handle of the channel plate.
- Try not to press the switch when somebody is on the edge, rooftop or shaft.
3、The water driven piece of the channel press should be introduced with an electric contact pressure check.
- It is prohibited to wear high impact points or work shoeless, and it is illegal to place your head or hands into the channel plate during dumping.
- It is prohibited to work the button with gloves and just utilize a wooden digging tool (bamboo edge) to empty the material.
6、Check whether the working buttons are adaptable and solid and regardless of whether the unloader is synchronized before work.
7、Check whether there is any garbage between the channel plates and regardless of whether there are kinks in the channel fabric before work, and tidy them up in time when found.
8、During the sifting system, notice the outpouring of filtrate, and when harm is found, record the number and fix or supplant the channel material on schedule.
9、Check whether the channel plate is distorted or broken, and supplant it in time when found. When supplanting the channel plate, eliminate the filtrate ramble first.
10、Flush the channel fabric as indicated by the guidelines to expand the penetrability of the channel material and work on the effectiveness of the channel press.
11、Before halting, quit taking care of and dump every one of the materials in the channel press prior to halting, and stopping with materials is totally precluded.
12、After the plate outline is slackened, one plate should be cleaned with a plastic digging tool after the slag has been released, and one more plate should be cleaned after the leftover slag has been released, and it is totally prohibited not to clean the lingering slag.
13、After emptying the plate slag, when cleaning the plate casing and channel material, guarantee that the hole is clear, and don’t permit the buildup to adhere to the fixing surface or taking care of channel.
14、When stacking the plate, when the plate outline is continuing on the primary pillar, it ought not be impacted or dropped, and the power ought to be equitably applied to forestall contacting the handle and harming the fixing surface.
15、Damaged channel fabric is viewed as supplanted on schedule. When introducing the channel fabric, it should be level and not collapsed to forestall harm and spillage of material when the plate outline is squeezed.
16、The destroyed plate and casing ought to be put away in a level spot to forestall misshapening.
17、The fixing surface of the channel plate should be perfect and flaw free, and the channel plate ought to be vertical and slick with the primary pillar, and ought not be one-sided in front or behind, if not the squeezing activity ought not be begun.
18, dumping plate slag during the time spent head and appendages into the channel plate is completely disallowed.
19、Leakage of sloppy water and harmed filter press cloth specification channel material ought to be changed and washed on schedule, dried and stacked flawlessly for brought together therapy.
20、Keep the channel material liberated from incorporations and kinks and keep the outer layer of the channel plate smooth and even.
- Investigation of normal flaws of the plate and edge channel press
1、Damage of the actual plate
The reasons for harm to the actual plate are.
1, when the slime is too thick or dry square abandoned, it will cause the blockage of the taking care of port, right now there is no medium between the channel plate just the strain of the water driven framework itself, as of now the actual plate is exceptionally simple to make harm due long time pressure.
2、If the stock is inadequate or the inventory contains unsatisfactory strong particles, it will likewise make the plate outline itself be harmed because of unreasonable tension.
3、If the stream outlet is impeded by solids or the stock valve or outlet valve is shut when beginning, the tension has no place to spill out to cause harm.
4、When the channel plate isn’t cleaned, now and again it will make the media spill out, when the spillage, the edge of the plate edge will be cleaned out a little channel, an enormous number of media spillage brought about by the tension would not ascent, mud be able to cake can not be framed.
Relating to the investigating strategies.
1、Use nylon cleaning scrubber to eliminate the mud from the delta
2, complete the cycle, decrease the volume of the channel plate
3、Check the channel fabric, clean the waste port, actually look at the power source, open the relating valve and delivery the tension
4 、Clean the channel plate cautiously and fix it
2、Water leakage between the plate and casing
The primary explanations behind water drainage between the plate and casing are
1、Low water driven tension
2、Folded channel fabric and openings in the channel material
3, fixing surface with protuberances.
Water leakage between the plate and casing is somewhat easy to manage, as long as the comparing expansion in water powered strain, substitution of the channel material or the utilization of nylon scrubber to eliminate the square on the fixing surface can be.
3、Unformed channel cake or lopsided channel cake
There are many justifications for why the channel cake can not be formed or lopsided, the stockpile of lacking or excessively flimsy, or the peculiarity of blockage can cause this peculiarity. For these disappointments to examine the causes exhaustively, and ultimately track down the specific issue, and afterward the indicative treatment to take care of the issue. The primary arrangements are: increment the stockpile, change the cycle, work on the inventory, clean the channel material or supplant the channel fabric, clean the blockage, clean the stockpile opening, clean the seepage opening, clean or supplant the channel material, increment the tension or siphon power, low-pressure start, and continually increment the strain and different strategies.
4、Sluggish activity of channel plate or simple to fall
Here and there an excess of oil and stain on the directing pole will likewise cause the channel plate to be delayed in real life and even tumble off. This time we should clean the aide pole on schedule and apply oil to guarantee its lubricity. One thing to note is that it is totally illegal to spread dainty oil on the aide bar, in light of the fact that meager oil is not difficult to tumble off to make the lower side extremely tricky, faculty working here for upkeep is exceptionally simple to fall, causing individual injury mishaps.
5、Failure of the water powered framework
The water powered arrangement of the plate and edge channel press primarily gives pressure, when the oil hole An is loaded up with more oil, the cylinder moves to one side and presses the channel plate to close it. At the point when the oil cavity B is loaded up with more oil, the cylinder moves to one side, and the channel plate is slackened. Because of the accuracy of the assembling, water powered framework disappointments are uncommon and can be settled with routine upkeep. By and by, because of mileage, oil breaks will happen after each year or so and the O-ring should be fixed and supplanted. Normal water driven disappointments incorporate inability to keep up with pressure and ill-advised development of the pressure driven chamber. Causes can not keep up with the strain of the principle reasons are oil spillage, O-ring wear and solenoid valve doesn’t work as expected, the normal treatment is to eliminate and really take a look at the valve, supplant the O-ring, cleaning and actually looking at the solenoid valve or supplant the solenoid valve. Water powered chamber drive isn’t reasonable is clearly air is fixed in the interior, then, at that point, as long as the framework siphoning can be, by and large can be immediately settled.
6, channel cake and channel material from awful
6, channel cake and channel material from terrible
(1) check the liquidity or grouping of the channel material has not changed, for example, liquidity or focus isn’t ordinary, it is important to broaden the filtration time, diminish the dampness content of the channel cake, with the goal that the channel cake and channel fabric from great;
(2) Check whether the dose is proper, change the measurement;
(3) Check whether the limit and strain of the feed siphon are reasonable, on the off chance that not, go to lengths to change the filtration time and other handling measures;
(4) Filter fabric remaining together, causing the mud cake can not be dumped regularly, the channel plate or pressure plate on the two sides of the lower part of the channel material integrated, the channel material and channel plate arrange, so the mud cake dumped without a hitch.
7、Insufficient filling of the channel chamber or void chamber
Deficient filling of the channel chamber or void chamber will prompt strain unevenness on the two sides of the channel plate, and the tension distinction between the different sides will cause the channel plate to be annihilated, causing this shortcoming is for the most part a channel blockage, the inward muck channel of the plate outline and the ooze pipeline of the stomach siphon ought to be checked, the normal blockage is a little piece of cloth or channel material collapsed to obstruct the opening, or the slop consistency is excessively huge, and the pipeline is hindered because of no backflushing pipeline when the channel press is halted.
8、Folding of channel fabric
Mud cake joined to the channel fabric (inadequate mud release), or deficient strain of the channel material suspension spring, will make the channel material overlay, should clean the channel material, supplant the spring, and reestablish the channel material to a level state.
At the point when the channel material is harmed, the mud attacks the channel plate from the burst and is released from the power source opening for all intents and purposes, making the filtrate turbid, when filtration can’t be completed, the channel fabric at the power source of the turbid fluid ought to be checked and fixed or supplanted with another channel fabric.
4、Repair of the channel plate
The reclamation innovation of the channel plate is as per the following:
Following a couple of long stretches of utilization, for reasons unknown, the channel plate is cleaned out at the corners for certain depressions. When the gouges show up, they will extend quickly until they influence the development of the channel cake. At first the channel cake turns out to be delicate, then, at that point, it transforms into a semi-ooze lastly the cake can’t be framed. Because of the extraordinary material of the channel plate, it is hard to fix and must be supplanted with another one, which brings about a maximum usage of extra parts. During this period, we attempted some fixing specialists, yet the impact has not been great. As of late, the circumstance at last pivoted when the oil surface fixing specialist was utilized all things being equal, and the preliminary impact was generally excellent, and the fixing impact was accomplished.
Explicit fix strategies are as per the following.
1, tidy up the furrow, releasing new surface to, accessible little saw sharp edge, and so forth tidy up
2, high contrast two fix specialist as indicated by the 1:1 proportion of the organization of good
3, the arrangement of good fix specialist covered ready, covered with a somewhat higher
4, immediately set the channel fabric, the channel plate pressed together, so the fix and channel material remain together, while crushing level sections
5、After crushing for a while, the cement will be normally framed and never again change, when it tends to be utilized ordinarily.
5、Cost correlation with other channel presses
If the crude water to be dealt with is 2000m3/day and the sewage treatment plant creating 8-10 t/d dry muck is gathered into a mud-water blend with a strong substance of around 3% (there will be contrasts in suspensions in various businesses and diverse treatment processes), it is around 300m3/day of mud-water combination; utilizing a rotator with a plan limit of 4-15m3/h, the industrial facility cost is around 100,000/set. A one-meter belt channel press is something like 100,000, and it has a treatment limit of around 4 to 12m3/h. A 120m2 programmed pull plate type plate and edge channel press costs almost 100,000, and its handling limit is around 3 to 10m3/h.
a. Flocculant utilization
In the rotator, because of the huge divergent power field, the fine slop can likewise be isolated from the water, so how much flocculant added is little, and the general dosing sum for blended muck dewatering is around 1.2 kg/tds, the ooze recuperation rate is over 95%, and the water content of the mud cake in the wake of dewatering is 65% to 80%; while the belt channel machine, to further develop the handling limit, the channel belt can’t be woven too thickly, and to keep the fine ooze from spilling out of the net, it is important to In request to keep the fine ooze from spilling out of the net, more flocculants are added to make the slime structure bigger flocs, and the general dosing sum for blended ooze dewatering is more noteworthy than 3 kg/tds, with an ooze recuperation pace of around 90% and a water content of around 80% in the mud cake subsequent to dewatering.
The dose of the decanter axis dewatering machine is significantly more efficient than that of the belt channel press, and the atomic load of the medications utilized in the decanter rotator dewatering machine is low and modest, while the sub-atomic load of the medications utilized in the belt channel press is high and costly. A one-meter belt channel press labors for eight hours every day with a measurements of four to five kilograms; a 355 decanter rotator dewatering machine labors for eight hours per day with a dose of a few kilograms, contingent upon the slime, and the axis can even accomplish better treatment results for some materials without adding drugs. For instance: paper making, fleece turning, acetylene gas slag, human stockpiling excrement, mine following sand and other coarse particles effortlessly encouraged materials, don’t require flocculants, while the belt channel press can not; this significantly diminishes the dosing and handling costs.
b. Power and water utilization
The power utilization of the axis being used is three to four kilowatts higher than that of the belt type machine, which is 30 yuan more each day as indicated by the estimation of eight hours of work each day. The axis, then again, doesn’t need water flushing during the whole dewatering process. Simply a modest quantity of water is utilized to wash the inward pit when closing down. A one-meter belt channel press, then again, expects sixty to seventy cubic meters of water each day for discharging of the channel belt. The discharge water is then gotten back to the sedimentation tank for reprocessing, which expands the expense by something like 150 yuan each day at an expense of 2.5 yuan per cubic meter of water, while the discharge cost is much higher with regular water, which saves 120 yuan each day and somewhere around 40,000 yuan each year. The plate and edge channel press needs to clean the channel fabric in the wake of handling the slop, if not it will influence the handling impact and develop the handling time, which is tedious and difficult.
c. Work utilization
The decanter axis has low work force, high computerization, straightforward activity, and one individual can oversee 2 to 3 units simultaneously; the belt channel press has muddled activity and high specialized prerequisites for working laborers, for the most part 1 to 2 individuals oversee 1 to 2 units; the plate and edge channel press has basic activity yet high work power and helpless work space conditions, by and large 2 individuals oversee 1 to 2 units, and the treatment of working laborers requires high treatment. Assuming the computation depends on 80 yuan for every individual each day, the decanter rotator is 80 yuan each day, the belt channel press is 160 yuan each day, and the plate and edge channel press is 100 to 160 yuan each day.
3、Use and support cost
The decanter rotator dewatering machine has not many wearing parts, just the V-belt and heading will be harmed, for example, substitution is two or three hundred yuan; the belt channel press has many wearing parts, in light of the qualities of open activity, the pivoting shaft, cog wheels, direction and channel belt are eroded by the sewage and running mileage, simple to harm, fix and substitution needs thousands or even huge number of yuan; the plate and edge channel press channel material will be broken, substitution additionally needs a couple thousand yuan.
