Closed filter press

Abstract

The invention relates to a closed filter press. A main beam of the filter press is provided with an upper frame body and a lower frame body; a fixed frame is arranged and installed on the upper end of the main beam; the fixed frame is welded with columns, and used for supporting and connecting an upper side frame; an upper transverse frame is arranged and welded with the upper frame body composed of the upper side frame and columns; the lower end of the main beam is welded with a fixed frame, and the fixed frame is welded with the columns and used for supporting and connecting a lower side frame; a lower transverse frame is arranged and welded with the lower frame body composed of the lower side frame and columns; both sides of the frame bodies are connected with a thrust plate and a base; a groove is installed in the frame bodies; a sealing plate is arranged and installed in the groove; the lower end of the lower frame body is provided with a material receiving tray; the upper end of the upper frame body is provided with a door side frame, and a door inner frame is welded with a transverse rib plate to constitute door-leaf upper covers; the upper end of the transverse rib plate is welded with a plate grip; and a sealing plate is installed in the door-leaf upper covers. According to the structure, the filter plate-filter cloth overall filter system is closed in the frame bodies, the leaked or ejected material is collected in the frame under control, and the sealing plate is made of an organic glass material which is transparent, and thus, can be used for observing the filtering conditions. The closed filter press has the advantages of compact structure and favorable closeness.

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
