High-efficient strong filter press

Abstract

An efficient strong press filter for removing water from material is composed of the endless material conveying netted band and its power unit, guide rollers, the deviation correcting unit and S-shaped press region, where there are press bearing table, upper and lower press plates, and releasing and stretching unit for netted band.

Description

technical field [0001] The invention relates to the technical field of filtration. Background technique [0002] At present, in the industry, the filter equipment used for the treatment of urban sewage and industrial wastewater such as chemical papermaking, textile, printing and dyeing, food, leather, pharmaceuticals, and various materials is generally box filter press and belt filter press. machine. Since the box filter press is a completely intermittent working equipment, its production efficiency is low and it is difficult to handle large batches of materials. Belt filter press is a continuous working filter equipment. It uses the mesh belt to convey the material to pass between the rollers, and uses the gap between the rollers to filter the material.

AI Technical Summary

Problems solved by technology

Since the box filter press is a completely intermittent working equipment, its production efficiency is low, and it is difficult to handle large batches of materials.

Belt filter press is a continuous working filter equipment. It uses the mesh belt to convey the material to pass between the rollers, and uses the gap between the rollers to filter the material. However, this kind of filter equipment has a small filter area and is difficult to use. High pressing pressure, so its filtration efficiency is still not high, and the water removal rate of the pressed material is not high

For some materials that not only need to be processed in large quantities, but also require a high water removal rate, the previous filtering equipment is not competent

For example, bean curds after oil extraction are finally made into dry products and used as feed after filtration. In order to reduce the energy consumption of drying, the water content after filtration is relatively high, generally below 60%. The current filtration The equipment either cannot meet the production requirements, and the latter cannot meet the moisture content requirements
