Complex type filter board of plate frame filter press

Abstract

A compound filter plate of a plate-and-frame type filter press pertains to the technical field of solid-liquid separation and aims at solving the problems of unreasonable structure of the filter plate and low overall stiffness and strength of the existing plate-and -frame type filter press. A plat disk scroll spiral casing is clamped and embedded in the filter plate body, the inner end head of the casing is closed, and the outer end pipe connector part is fixedly connected on a side frame of the filter plate. The structure filter plate is novel, the usage is convenient, and the compound filter plate is applicable to all types of plate-and-frame type filter presses for assembly and can be widely used in the solid-liquid separation of various materials in chemical industry, foods, medicine, metallurgy selection, environmental protection sewage treatment and other industrial fields, thus having broad popularization and application prospects.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation and relates to a filter plate of a plate and frame filter press. Background technique [0002] With the rapid development of the filtration industry, the technical requirements for the filtration effect of materials and its filtration machinery components are also getting higher and higher. Users are eagerly praying for large filter plates with high filtration efficiency, high pressure resistance, and good temperature resistance. In the known technology, the core component filter plate of the existing plate and frame filter press is mainly a flat plastic filter plate, which has unique physical and chemical properties compared with the filter plate of metal material, such as high specific strength, processing and manufacturing process It is simple and has a wide range of applications for filtering materials, etc., and has been widely used. However, limited by its material and struc...

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art and solve the problems of unreasonable filter plate structure and low overall rigidity and strength of the existing plate and frame filter press, the purpose of the present invention is to provide a novel structure, innovative design, which adopts metal and plastic The composite structure with the advantages of both in one and complementary advantages can not only effectively adjust the temperature of the filter plate, but also enhance the rigidity, tensile and bending strength of the filter plate, eliminate the influence of thermal stress on the fatigue strength, and improve the service life of the filter plate , does not change the geometric shape of the working surface of the existing general-purpose filter plate, and is easy to assemble to the existing plate-frame filter press. Various types of functions are common, the manufacturing process is reasonable, the production cost is low, and the new filter plate of the plate-frame filter press is easy to use.
