SUMMERY OF THE UTILITY MODEL
According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the utility model provides a take filter-pressing equipment of filter-pressing board leak hunting function, solves above-mentioned problem.
Filter-pressing equipment of area pressure filter plate leak hunting function, which comprises a frame, be equipped with a supporting beam in the frame, thrust plate and pressure strip are equipped with on a supporting beam, be equipped with a plurality of pressure filter plates between thrust plate and the pressure strip, form the filter chamber between the pressure filter plate, frame one side is equipped with the hydraulic pressure station, be equipped with feed liquor hole and liquid outlet on the pressure filter plate of constituteing every filter chamber, every feed liquor hole is all through the total pipeline of solitary feed liquor branch pipeline intercommunication feed liquor, every liquid outlet all is through the total pipeline of solitary liquid outlet branch pipeline intercommunication liquid outlet, all be equipped with tee bend pipe fitting on every feed liquor branch pipeline, the total pipeline of a branch road intercommunication feed liquor of tee bend pipe fitting, a branch road intercommunication feed liquor hole, another branch road intercommunication detection pipeline, be equipped with the ooff valve on the detection pipeline.
Preferably, a pressure gauge is arranged on the detection pipeline.
Preferably, each liquid outlet branch pipeline is provided with a switch valve.
When the filter press works, after the filter press is compressed, the feeding pump is started, the detection pipeline is kept closed, feed liquid enters each filter chamber from the liquid inlet main pipeline and the liquid inlet branch pipeline, the filter press liquid outlet condition and the filter plate leakage condition are observed, the filter chambers are gradually filled, and when liquid does not flow out from the liquid outlet hole or only a small amount of liquid exists, the filter chambers are proved to be completely filled to form filter cakes. If the filter plate leaks, the switch valves on all the liquid inlet branch pipelines are closed, then the switch valves on the detection pipelines are independently opened one by one, water or air is introduced to detect leakage of each independent filter chamber, and the part which is leaked is detected to be checked in detail.
