A closed filter press

Abstract

A closed filter press, the upper and lower frames are arranged on the main beam of the filter press, the fixed frame is installed on the upper end of the main beam, the fixed frame is welded with columns and supports to connect the upper frame, and the upper horizontal frame is welded with the upper frame and columns to form the upper frame The fixed frame is welded at the lower end of the main girder. The fixed frame is welded to the column and the support to connect the lower frame, and the lower horizontal frame is set to weld the lower frame and the column to form the lower frame body. The groove is installed, and the sealing plate is installed in the groove. The lower end of the lower frame body is provided with a material receiving tray, and the upper end of the upper frame body is provided with a door frame and a door inner frame welded with a transverse rib plate to form a door leaf type upper cover. There is a sealing plate installed in the door-shaped upper cover. This structure seals the filter plate and the filter cloth as a whole filter system in the frame body. Material leakage or spraying is controlled and collected in the frame. The sealing plate is made of plexiglass material with transparent observation and filtration. The structure is compact and the sealing performance is good.

Description

technical field [0001] The invention belongs to the field of filter presses, and more specifically, relates to a closed filter press. Background technique [0002] The filter press is the main filtration equipment in the solid-liquid separation industry. The filter plate is installed on the main beam of the filter press, and the filter plate is pressed by the compression device to form a sealed filter chamber. When the material is filtered, it is injected into the filter chamber by the pressure of the feed pump. , the particles in the material are intercepted by the filter cloth in the filter chamber, and a filter cake is formed in the filter chamber, and the filtrate is discharged from the liquid outlet hole of the filter plate to achieve the purpose of solid-liquid separation. [0003] The filter press is suitable for the filtration of various materials. In the field use, it is found that the sealing surface of the filter plate of the filter press has material leakage or i...

Problems solved by technology

[0003] The filter press is suitable for filtering various materials. In the field use, it is found that the sealing surface of the filter plate of the filter press has material leakage or injection when filtering. Because the feeding pressure of the filter material is different, there are Even in normal use, the material sometimes leaks. The filter plate is often subjected to high pressure and compression during filtration. In long-term use, it is inevitable that there will be deformation and material leakage. Spraying, or when the filter cake is removed, the filter cake will stick to the sealing surface of the filter plate and cause leakage. The above reasons can cause material leakage or spraying on the sealing surface of the filter plate, and some materials in the chemical industry contain harmful objects. The environment is serious and at the same time it causes personal injury, which makes the operators unsafe in production and pollutes the environment at the work site, which directly affects economic benefits
