Problems solved by technology

At present, the filter membrane on the filter plate mainly adopts a microporous ceramic filter membrane. Although it has high filtration accuracy, its cost is high, which will increase the manufacturing cost of solid-liquid separation equipment; in addition, this filter membrane It is easy to be blocked and damaged during operation, its operation stability is poor, and its service life is short. Maintenance and replacement will not only affect the normal and continuous production of solid-liquid separation equipment, but also increase operating costs.
Overall, the economy and practicability of the aforementioned filter plates are poor

Abstract

The invention discloses a filter plate for solid-liquid separation. The filter plate is assembled in a separation chamber of solid-liquid separation equipment and is used for solid-liquid filtering and separation of slurry in the separation chamber. The filter plate comprises a plate frame, which internally has a filtrate cavity capable of discharging filtrate, the plate frame has at least one filter plate, the filter plate is provided with a plurality of filtrate channels communicated with the filtrate cavity, and the outer surface of the filter plate is wrapped with a filter cloth, which covers the filtrate channels on the filter plate. The filter plate for solid-liquid separation provided by the invention has the characteristics of simple structure, low manufacturing cost, long servicelife, stable operation and the like, not only can effectively reduce the manufacturing and maintenance cost of solid-liquid separation equipment, but also can effectively improve the operation stability of the solid-liquid separation equipment, and is economical and practical.

Description

technical field [0001] The invention relates to a filter plate for solid-liquid separation, which is especially suitable for solid-liquid separation of a concentrator. Background technique [0002] The purification of slurry in industrial production is realized by solid-liquid separation, and the thickener is taken as an example for illustration. [0003] Thickener (that is, high-efficiency thickener) is widely used in metallurgy, mining, coal, chemical industry, building materials, environmental protection and other industries. It is a continuous working concentration and clarification equipment. The slurry containing solid and liquid is filtered and purified through multiple filter plates arranged in the concentration chamber (solid-liquid separation chamber) of the concentrator. The liquid material filtered by the plate enters the filtrate cavity in the filter plate and is discharged due to pressure, so as to realize solid-liquid separation. It can be seen from this tha...
