Board casing filter press is the handles in the light of mud equipment in sewage disposal system, its action is sewage disposal after silty undertake filter-press, form chunk filter cake (slimy cake) , so that eliminate.

Board casing filter press transmits the 5 much such as system and electrical system to comprise by system of filter press filter plate, hydraulic pressure, filter press casing, filter plate. The principle that job of board casing filter press runs is simpler, apply force impaction by hydraulic pressure first board casing group, of precipitation silty by among enter, distributing between each filter cloth.

As a result of board casing impaction, silty cannot outside excessive, it is under the high pressure of screw pump and membrane pump, silty medium moisture by filter cloth in oozy, flow into backwater to be in charge of, and slimy cake stays in cavity. Board casing discharge is pressed later, filter plate is pulled open, slimy cake relies on gravity to fall, pull by the car, because this says filter-press process,be last working procedure in sewage disposal craft. The main parameter of board casing filter press and data have: Board casing counts 125, but enlarge reachs 150 (149 separate speech) , board dimension 1300×Thick 30mm of cake of 1300mm, mud, filter area 297.6 ㎡ filters the pressure 16bar, biggest shut pressure 368bar.
368bar of the pressure when impaction of board casing filter press, filter pressure 16bar, last in casing of moving medium plate impaction, the water among from inside silty medium oozy flow, as a result of pressure bigger reason, board piece itself and filter cloth are easy appear to damage or jam. Additional, as a result of mud of oily be soiled be infected with, carriage system often also can get stuck acerbity or walk flabby.
One, board piece the attaint of itself. Cause board piece the reason that itself damages has:
1, pass when mud stiff or when doing a bequeath, can cause those who offer makings opening to jam, there was the pressure that medium goes itself of hydraulic pressure system only between filter plate right now, right now board piece because itself is long press press causes damage extremely easily.
2, offer makings inadequacy or offer when improper solid grain is being contained in makings, same meeting creates board circle this experience force is overmuch so that damage.
3, if pour out of,shut lay makings a powerful person or give a powerful person, pressure the discharge outside nowhere, so that cause damage.
4, filter plate clears when ungodliness, can cause the leak outside medium sometimes, once outside discharge, board casing brim can be eroded to give a canaliculus to come, of medium a large number of outside discharge causes pressure to cannot lift, slimy cake cannot be formed.
