- What are the explanations behind showering material between channel plates?
a. High feed pressure causes showering material. Numerous clients don’t introduce pressure check on the feed pipe, which prompts uncontrolled feed pressure and ultimately causes splashing material.
b, the channel plate pressure isn’t sufficient top fixing power, after the feed pressure rises, the power between the channel plate will channel plate set open brought about by splashing material.
c, the channel plate fixing surface has channel cake and other flotsam and jetsam connected to the surface, the channel plate pressure generally has a huge hole exists, so the fixing surface ought to be cleaned subsequent to eliminating the channel cake.
d. The fixing surface of the channel plate as of now has a through groove or the channel plate itself is harmed. - How might I tell when the muck is squeezed dry utilizing the plate and casing channel press?
It is hypothetically difficult to press the ooze dry in a plate and casing channel press, it must be perceived as the finish of this taking care of cycle, according to the accompanying two places.
a. The feed pressure has arrived at the maximum furthest reaches of the set feed pressure.
b. How much fluid released from the channel plate is essentially diminished.
To additionally lessen the water content of the channel cake, you can adopt the accompanying two strategies.
a. Increment the feed pressure (gave the water driven chamber pressure is adequate).
b, through the compacted air, blowing air to remove the dampness. - What are the reasons and countermeasures for the low tension of the channel plate conclusion?
In the genuine activity of the plate and casing channel press, assuming the fluid level of the water powered station tank is low, it could be brought about by the presence of breaks in the water powered pipeline, which might bring about pressure misfortune in the water powered station; there is a huge position blunder in the establishment of the channel plate limit discovery gadget, so the channel plate dislodging control framework raises the activity, while the control pressure driven siphon quits working rashly; the channel plate shutting pressure is set excessively little, which may likewise bring about a little tension for the culmination of the channel plate squeezing.
Treatment: Regular examination of each working piece of the channel press, when the water powered oil level is viewed as too low, the pressure driven oil ought to be filled into the water powered station tank on schedule to guarantee that it meets the prerequisites of typical activity.
Simultaneously, check the fixing of the pressure driven pipeline joints and the respectability of the water powered pipeline, when the joints are viewed as spilling or the chamber seal ring is worn, the O-ring or seal ring ought to be supplanted, and assuming the oil circuit is releasing, the oil circuit ought to be upgraded on schedule to completely ensure the honesty of the pressure driven pipeline.
Assuming the channel plate set up recognition gadget is introduced in front, the oil siphon should quit working ahead of time to rearrange the place of the channel plate set up gadget to guarantee that the end pressure meets the necessities. Channel press water powered chamber shutting pressure boundaries set worth is little, water powered oil siphon right on time into the stop state, for the present circumstance, should be shut to finish the strain boundaries reset to guarantee that it satisfies the end pressure guideline prerequisites. - What are the causes and countermeasures for the commotion created by the water powered arrangement of the channel press?
During the time spent squeezing the channel press, the pressure driven framework has an abnormal commotion, mostly because of free latches in the framework or the water powered oil thickness is excessively huge.
Treatment: Check the framework latches, assuming that there is free, attach the clasp. For water driven oil thickness is excessively huge, diminish its china filter press consistency can be.
05、What in the event that the channel plate activity isn’t synchronized during the end cycle of the channel press?
At the point when the channel press is working, there is an obstructing and linkage connection between its inward mechanical designs. When the channel plate doesn’t move after the end activity, check whether the dumping streetcar is in the underlying situation on schedule.
On the off chance that the releasing streetcar doesn’t move and the position doesn’t change, then, at that point, further check whether the underlying position location gadget is working regularly, and the identification gadget is messed up to be updated on schedule.
- How to work the channel plate in the event that it can’t be opened?
After the channel press is blown, it frequently creates the impression that the channel plate doesn’t open or stops irregularly when the activity is relaxed.
Treatment: First of all, the tension arrival of the channel plate should be in accordance with the strain standard prerequisites. When the strain isn’t completely finished, the activity of the hindering relationship will prompt issues with the arrival of the channel plate.
Also, on the off chance that the framework isn’t renewed on schedule because of unnecessary loss of pressure driven oil throughout long activity, it will make the framework lacking oil supply, bringing about helpless progression of water powered chamber work and discontinuous peculiarity.
Three, channel press wellbeing activity focuses
01、When the channel press is working regularly, the administrator will not put his feet, hands or head into the channel plate of the channel press or notice the belt transport or the focal space underneath from between the cuts of the channel plate pulled open. It is illegal to put devices on the pulling snare outline and the handle of the channel plate.
- It isn’t permitted to press the switch when there are individuals on the edge, rooftop or shaft.
03、The water driven piece of the channel press should be introduced with an electric contact pressure measure. - It is illegal to wear high impact points or work shoeless, and it is totally taboo to place head or hand into the channel plate during dumping.
- It is prohibited to work the button with gloves and just utilize a wooden digging tool (bamboo cutting edge) to empty the material.
06、Check whether the working buttons are adaptable and solid and regardless of whether the unloader is synchronized before work.
07、Check whether there is any trash between the channel plates and regardless of whether there are kinks in the channel material before work, and tidy them up in time when found.
08、During the separating system, notice the outpouring of filtrate, and when harm is found, record the number and fix or supplant the channel fabric on schedule.
09、Check the channel plate for disfigurement, break, and so on and supplant it in time when found. When supplanting the channel plate, eliminate the filtrate water ramble first.
10、Flush the channel fabric as indicated by the guidelines to expand the porousness of the channel material and work on the proficiency 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 denied.
12、After the plate outline is released, 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 completely prohibited not to clean the lingering slag.
13、After emptying the plate slag, when cleaning the plate edge and channel material, guarantee that the opening 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 shaft, 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 material 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 edge ought to be put away in a level spot to forestall deformity.
17、The fixing surface of the channel plate should be spotless and sans wrinkle, and the channel plate ought to be vertical and slick with the primary bar, and ought not be one-sided in front or behind, any other way the squeezing activity ought not be begun.
18, dumping plate slag during the time spent head and appendages into the channel plate is totally disallowed.
19、Leakage of sloppy water and harmed channel fabric ought to be changed and washed on schedule, dried and stacked conveniently for brought together therapy. - Keep the channel material liberated from incorporations and kinks and keep the outer layer of the channel plate level and smooth, and the handle of the channel plate ought to be held gently.
IV. Cost examination with other channel presses
Picture
- Venture cost.
In the event that the crude water to be dealt with is 2000m3/day and the sewage treatment plant creating 8-10 t/d dry muck is moved into a mud-water blend with a strong substance of around 3% (there will be contrasts in suspensions in various treatment processes in various ventures), that is, around 300m3/day of mud-water combination; the utilization of a LW355 axis can meet the creation needs, and the LW355 rotator is intended to deal with 4 to 15m3/h, ex-plant cost around 100,000/unit. A one meter belt channel press is no less than 100,000 and it has a limit of around 4 to 12m3/h. A 120m2 programmed pull plate type plate and casing channel press costs almost 100,000, and its handling limit is
02、Operating expense.
a. Flocculant utilization
In the rotator, because of the enormous radiating power field, the fine muck can likewise be isolated from the water, so how much flocculant added is less, and the general dosing sum for blended ooze dewatering is around 1.2 kg/tds, the ooze recuperation rate is over 95%, and the water content of the mud cake subsequent to 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 slime from spilling out of the net, it is important to add more flocculant. To keep the fine muck 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 prominent than 3 kg/tds, with an ooze recuperation pace of around 90% and a water content of around 80% in the mud cake in the wake of dewatering.
The dose of the decanter rotator dewatering machine is significantly more efficient than that of the belt channel press, and the atomic load of the medications utilized in the decanter axis 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 per day with a measurements of four to five kilograms; a 355 decanter rotator dewatering machine labors for eight hours every 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 incredibly decreases the dosing and handling costs.
b. Power and water utilization
The power utilization of the rotator 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 computation 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 flush the inward depression 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 builds the expense by no less than 150 yuan each day at an expense of 2.5 yuan per cubic meter of water, while the discharge cost is considerably 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 ooze, if not it will influence the handling impact and develop the handling time, which is tedious and relentless.
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 casing channel press has basic activity however high work power and helpless workplace conditions, by and large 2 individuals oversee 1 to 2 units, and the treatment of working specialists requires high treatment. Assuming the computation depends on 80 yuan for each 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.
- Use and support costs.
The decanter axis dewatering machine has not many wearing parts, just the V-belt and orientation will be harmed, for example, substitution is a couple hundred yuan; the belt channel press has many wearing parts, on account of the attributes of open activity, the turning shaft, cog wheels, heading and channel belt are consumed 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 fabric will be broken, substitution likewise needs a few thousand yuan.
