Filter plate cake unloading scraper device of horizontal filter press

Abstract

The invention discloses a filter plate cake unloading scraper device of a horizontal filter press, which belongs to the technical field of filter press equipment and comprises a fixed table and a scraper push plate, a connecting block is fixedly mounted at the bottom end of the scraper push plate, a connecting plate is fixedly mounted at the bottom end of the connecting block, and a first cushionblock and a second cushion block are arranged on the upper surface of the fixed table. The fixing table is used for buffering and supporting the connecting plate, a first pneumatic cylinder is arranged below the fixing table, a second pneumatic cylinder and a third pneumatic cylinder are arranged on the two sides of the first pneumatic cylinder respectively, and the output end of the first pneumatic cylinder is movably connected with a first pneumatic rod. According to the filter plate cake unloading scraper device of the horizontal filter press, the plurality of pneumatic cylinders are arranged to drive the plurality of pneumatic rods to enable the scraper push plate to scrape off a filter cake surface adhered to a filter plate sealing surface and a filter chamber of the filter press, sothat the labor intensity of workers is reduced, the material filtering cycle period is short, the service life of filter cloth is prolonged, the cost is reduced and the filtering efficiency is improved, simple operation and safe use.

Description

technical field [0001] The invention belongs to the technical field of filter press equipment, in particular to a cake unloading scraper device for a filter plate of a horizontal filter press. Background technique [0002] The filter press is the filtration equipment in the solid-liquid separation machinery industry. The box filter plate is the main filter element of the horizontal filter press. When the horizontal filter press is filtering, the material is injected into the filter chamber of the filter plate by the feed pump. The filter cloth or other filter media installed on the filter plate retains the particles in the material retained in the filter chamber, and the filtrate is discharged from the outlet hole to form a filter cake in the filter chamber, and then the filter plate is pulled apart by the filter press to make the filter The cake will automatically fall to remove the filter cake to achieve the purpose of filtration. Due to the development and expansion of t...

AI Technical Summary

Problems solved by technology

Due to the development and expansion of the solid-liquid separation industry and the wide application of filtration technology, when the filter press feed filter is completed and the filter plate is pulled to remove the filter cake, some filter materials and filter cakes contain stickiness and are easy to stick to the filter chamber and the filter plate. If it falls on the sealing surface, workers can only clean it with high-pressure water, but the cleaned filter cake will easily block the pipeline when it enters the drainage pipe. At the same time, it will cause the filter cake to be filtered for the second time, which wastes energy and increases production costs. The filter cake on the surface makes the filter chamber often leak material, failing to achieve the purpose of filtration

[0003] In the prior art, the sealing surface of the filter plate and the filter cake in the filter chamber are generally removed manually, which makes the workers time-consuming and laborious, and also increases the cost, resulting in an increase in the filtration cycle, affecting the filtration efficiency, and thus affecting the production.
