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...

Embodiment Construction

[0017] as attached figure 1 , figure 2 In the shown embodiment, the present invention is a box-type filter plate formed by bonding two half-type filter plates with an adhesive layer 8. A filter plate is embedded in the body with a center feeding hole 5 as the axis of the filter plate. The flat-disc scroll spiral sleeve 3, the inner end of the sleeve 3 is closed, and the outer end pipe joint is fixedly connected to the frame of the filter plate and connected to the double valve 4 disclosed in Chinese Patent No. 200620023302.1. Several filter cloth supports 6 are formed on the outer filter surface of the plate body and the cover is connected with the filter cloth layer 7 .

[0018] See attached image 3 In an embodiment, the pipe joint of the casing 3 of the present invention is fixedly connected to the pull frame of the filter plate.
