Problems solved by technology

However, due to the deformation problem of the diaphragm being repeatedly bulged and flattened, it directly affects the damage of the diaphragm and makes it unusable. The diaphragm must be replaced to continue filtering. This will inevitably increase the requirements for the selection of diaphragm materials and narrow the scope of application.

Abstract

The invention provides a vacuum low-temperature drying dehydration filter plate which comprises a plate body and an annular plate frame surrounding the plate body. The plate body comprises a first flow converging pipe and a plurality of branch pipes, wherein the first flow converging pipe is arranged on the circumference of the plate body and connected with the plate body; and the branch pipes are communicated with the two sides of the first flow converging pipe. The first flow converging pipe is provided with at least one liquid inlet and at least one liquid outlet. Through the vacuum low-temperature drying dehydration filter plate, a drying effect is achieved under vacuum by utilizing the heat exchange principle, it can be guaranteed that the filter plate does not deform obviously in the squeezing and vacuumizing process; the sealing performance is good, and a leakage phenomenon of a medium in the plate body is avoided.

Description

technical field [0001] The invention relates to the field of filter press components, in particular to a vacuum low-temperature drying dehydration filter plate. Background technique [0002] The filter plate is a very important component of the plate and frame filter press. Its quality is directly related to the normal use of the entire plate and frame filter press. The main functions of the filter plate are: [0003] 1. The filter plate can be used to store filter cake. Because the two sides of the filter plate of the plate and frame filter press are concave, the space between the two pieces can be used to store the filter residue intercepted by the filter cloth, and there will be blind spots on the bottom of the filter plate, mainly for When there are many filter cakes, the friction between the filter plate and the filter cake can be increased, so as to better support the filter cake. [0004] 2. Increase the area of ​​the filter chamber wall, thereby better increasing t...
