The utility model Treatment of Sludge is as follows with the working principle of canvas press cloth cleaning system:
Filter press 9, which is in, compresses non-feed state, and acidic cleaner is added first in auger tank 1 or alkalinity is clear
Lotion, then addition water stirs evenly according to a certain percentage is configured to ejected wash water；It closes into mud pneumatic ball valve 7, blowback Pneumatic ball
Valve 10, filtrate discharge pneumatic ball valve 4 and ejected wash water are vented pneumatic ball valve 5, open ejected wash water water inlet pneumatic ball valve 12, ejected wash water is returned
It flows pneumatic ball valve 8 and pipeline recycles chemical pump 14, ejected wash water enters in filter pad chamber from extraction in auger tank 1, filter pad chamber
Air is discharged by ejected wash water reflux line 2 in room, and to be filled with ejected wash water in filter pad chamber, ejected wash water flows back from ejected wash water
Pipeline 2 back flows back into auger tank 1 by cleaning water purification installation 15, can close ejected wash water water inlet pneumatic ball valve at this time
12 and ejected wash water flow back pneumatic ball valve 8；Ejected wash water stops half an hour (fixed according to concrete condition) in filter pad chamber, herein mistake
Cheng Zhong, acid in ejected wash water or alkalinity are held agent and are reacted with the indoor filter cloth of filter pad chamber, filter plate surface crystallization body, and removal is pressed
Filter filter cloth, filter plate surface crystallization body, and tamper in canvas press cloth, filter plate is subjected to immersion softening；It is then turned on cleaning
Water reflux 8 half of pneumatic operated valve opens ejected wash water water inlet pneumatic ball valve 12, opens pipeline and recycle chemical pump 14, ejected wash water is continuous
Circulation in, and since ejected wash water reflux pneumatic ball valve 8 has only opened half, it is to locate that ejected wash water recycle in filter pad chamber
In there is pressure condition, in the process, ejected wash water constantly impacts the softened tamper of canvas press cloth, filter plate, by filters pressing
Tamper is taken away with ejected wash water in machine filter cloth, filter plate, and tamper is trapped in cleaning by cleaning water purification installation 15 by ejected wash water
In water purification installation 15, ejected wash water becomes clarification again and enters in auger tank 1, finally that canvas press cloth, filter plate is all clear
Wash clean.It finally closes pipeline circulation chemical pump 14, ejected wash water water inlet pneumatic ball valve 12, clear water and washes reflux pneumatic ball valve 8, open
Ejected wash water is vented Pneumatic ball 5, and the cleaned water reflux line 2 of ejected wash water is final again by cleaning water purification installation 15 in filter pad chamber
It fully enters in auger tank 1, above is exactly the process for completely washing canvas press cloth.
Canvas press cloth has been cleaned every time to require that the filter cloth 18 cleaned in water purification installation 15 is removed and cleaned,
It cleans water purification installation 15 to intercept the dirts such as sludge in cleaning water purification installation 15 using the strainability of filter cloth 18, cleaning
Water can but pass through, and realize in each canvas press cloth cleaning process, and dirt can completely remove, and ejected wash water can be fully achieved and be followed
Ring utilizes, and cleaning cost is effectively reduced, and reduce the discharge of sewage.
The utility model can not only realize immersion to filter cloth, cleaning, and can be realized immersion to filter plate, clear
It washes, can be realized full automation operation, reduce labor intensity of operating staff；Ejected wash water is during recycling using clear
Wash water purification device 15 is filtered, and removal cleaning dirt will not generate sewage, and ejected wash water, which is realized, to be recycled, and saves cleaning
Cost；It can be realized the acidity or alkalinity cleaning for sludge quality and filter cloth, filter plate stopping state configuration various concentration
Liquid, and setting is impregnated, scavenging period；Filter cloth will not be caused in filter cloth cleaning process to damage and filter cloth can be softened, prolonged
Long filter cloth service life, is effectively reduced production run cost.
