A plate and frame filter press for waste treatment

Abstract

The invention relates to the technical field of solid-liquid separation, and discloses a plate-and-frame filter press for waste treatment, which includes a frame, and a filter unit block is arranged above the frame, and the filter unit block includes a filter frame and a filter frame. plate, the filter unit block is composed of multiple sets of filter frames and filter plates, the side of the filter unit block is provided with a push plate, and a pressing assembly is arranged between the two adjacent filter unit blocks, the The pressing assembly is provided with a transmission mechanism, and the transmission mechanism is connected with a pressure self-adjusting device. The plate and frame filter press for waste treatment uses the foldable performance of the movable filter cavity, so that the filter frame and the filter plate can move towards each other to fully squeeze the filter cake, reduce the moisture content of the filter cake and reduce the moisture content of the filter cake. Volume, increase the free space of the filter chamber, make full use of the limited volume filter chamber to increase the volume of the suspension filtered by the plate and frame filter press in a single operation, and improve the filtration efficiency of the plate and frame filter press.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to a plate and frame filter press for waste treatment. Background technique [0002] Filter press is a kind of equipment for solid-liquid separation of materials through pressure filtration. It is widely used in chemical industry, dyestuff, petroleum, ceramics, medicine, food, smelting and sludge treatment in various industries, etc., especially in the treatment of urban sludge. It has good separation effect and wide adaptability, especially for the separation of sticky matter, which has unique advantages. The plate and frame filter press consists of a set of filter chambers arranged alternately through filter plates and filter frames. There are grooves on the surface of the filter plate, and the protruding parts are used to support the filter cloth. There are through holes on the filter frame and the filter plate, which form a complete channel after assembly, and ...
