Device and method of filter press for quickly discharging material and cleaning filter cloth

Abstract

The invention relates to a device and a method for rapid discharge and cleaning of a filter cloth of a press filter, and belongs to the machinery. The device comprises a filter plate group, a filter plate lower cable pulley group, a filter plate upper cable pulley group, a cloth guide cable, a filter cloth group, a clamp, a filter cloth cleaning unit, an arm guide slot group, an opening plate arm group and an opening plate arm transmission mechanism. The method for rapid discharge and cleaning of the filter cloth of the press filter comprises the step of local reflux of materials, the washing step of a material guide pipe, the cleaning step of the clamp, the discharging step of a filter cake and the washing step of the filter cloth. The device and the method have the advantages that the discharge of the filter cake is rapid and can achieve the full automation, the filter cloth is cleaned rapidly, the scope of the materials which can be filtered is wider, and the practicality is strong.

Description

Device and method for quick unloading and cleaning filter cloth of filter press technical field The invention relates to machinery, in particular to a device and method for quickly unloading and cleaning filter cloth of a filter press. Background technique As we all know, filter presses currently on the market are widely used in the solid-liquid separation process of fluid slurry in the industry. When unloading mud cake, they generally adopt a piece-by-piece method for unloading. Generally, a filter press of 70 pieces is used. The unloading time of the board is about 15-20 minutes, and the cleaning time of the filter cloth is about 4-6 hours, which takes up a considerable amount of time in the entire dehydration cycle. Facing materials that are not easy to dehydrate and filter, the method of reducing the thickness of the mud cake is often used However, too thin dewatered cake is not conducive to the mud cake unloading operation. During the plate unloading process, the mud ...
