Van type plate and frame filter with multiple filter cloth cleaned simultaneously and cleaning method thereof

Abstract

The invention relates to the technical field of cleaning equipment and methods of a van type plate and frame filter, and specifically relates to a van type plate and frame filter with multiple filtercloth cleaned simultaneously and a cleaning method thereof. The van type plate and frame filter with multiple filter cloth cleaned simultaneously comprises a press plate, a press bottom plate, and a plurality of filter units arranged between the press plate and the press bottom plate in parallel in sequence, wherein each filter unit comprises a filter plate and a filter cloth structure, the pressplate can press the plurality of filter units under driving of a drive mechanism, so as to change the clearances between the plurality of filter units and realize filtering, a plate opening chain is arranged between the press plate and the press bottom plate, the plate opening chain sequentially passes through fixed connection points arranged on the filter plates of all filter units, and the length of the opening plate chain between the fixed connection points of two adjacent filter plates is equal. Compared with the prior art, the van type plate and frame filter with multiple filter cloth cleaned simultaneously has the advantages that all filter plates can be opened once, mud can be unloaded once, all filter cloth can be cleaned simultaneously, the van type plate and frame filter takes less time in cleaning, and the working efficiency of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment and methods for a van-type plate-and-frame machine, in particular to a van-type plate-and-frame machine for simultaneous cleaning of multiple filter cloths and a cleaning method thereof. Background technique [0002] Plate and frame filter press is a kind of equipment to realize solid-liquid separation. The filter press arranges the filter plates with filtrate passages in parallel, and there is a filter cloth between the filter plates and adjacent filter plates, and the filter plates are pressed tightly so that A filter press chamber is formed between the filter plate and the adjacent filter plate. The suspension is continuously pumped into the filter chamber of the filter press, the filter residue is trapped in the filter chamber to form a filter cake, and the filtrate passes through the filter cloth and flows away from the drainage channel of the filter plate. Stop feeding after the ...

Problems solved by technology

Stop feeding after the pump reaches the set pressure. At this time, if the water content of the filter cake needs to be further reduced, the filter cake needs to be squeezed twice. After the second squeeze time is up, the filter plate is opened to unload the filter cake. Because the filter cake has Adhesion, the plate and frame machine needs to clean the filter cloth after unloading the filter cake to ensure good water permeability in the next filtration. The conventional plate and frame machine filter cloth is cleaned one by one, and the cleaning mechanism takes a long time , which prolongs the running time of the plate and frame machine and reduces the efficiency of the equipment. Therefore, it is necessary to design a van-type plate and frame machine that can clean multiple filter cloths at the same time, so as to reduce the cleaning time of the filter cloth of the plate and frame machine and improve the working efficiency of the equipment.
