Large circular plate high-pressure automatic filter press

Abstract

The invention discloses a large circular plate high-pressure automatic filter press, which relates to the field of environmental protection equipment and mainly comprises a rack part, a filtering part, a hydraulic system, an automatic plate pulling device and an electrical control system. The single-machine yield is increased by adopting large-area circular filter pressing plates, and meanwhile, the sealing surface is used for ensuring the sealing property of each filter chamber during filter pressing, so that the phenomenon of slurry leakage between the filter plates during high-pressure filter pressing is effectively avoided. Meanwhile, double oil cylinders are horizontally arranged side by side, so that the space is saved, and the filtering pressure can be effectively improved; a mode of simultaneously feeding slurry from two ends is also adopted, so that the filter pressing time is further shortened, and the filtering efficiency is improved. Besides, the automatic filter press provided by the invention is integrally designed and manufactured by machine, electricity and liquid, can realize automatic control of various processes such as filter plate pressing, filtering, squeezing, filter plate loosening, discharging and the like, and is high in practicability.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a large disc high-pressure automatic filter press. Background technique [0002] Automatic filter press is a kind of pressurized filtration equipment, which is suitable for solid-liquid separation of various suspensions. It has the advantages of wide application range, good separation effect, simple structure, convenient operation, safety and reliability, etc. It is widely used in ceramic mud, Sand washing, tailings treatment, industrial wastewater and urban domestic sewage treatment and other fields that require solid-liquid separation. [0003] The current filter press mostly uses square filter plates, but the square filter plates have small area, low output, and low filtration pressure. When the pressure and flow rate of the material pump are too high, slurry leakage will occur, which cannot be used for ceramic filter press. Moreover, the existing filter pres...

AI Technical Summary

Problems solved by technology

[0003] The current filter press mostly uses square filter plates, but the square filter plates have small area, low output, and low filtration pressure. When the pressure and flow rate of the material pump are too high, slurry leakage will occur, which cannot be used for ceramic filter presses.

Moreover, the existing filter press only feeds the slurry from one side at the tail, not only the pressure of the slurry is small, but also the flow rate is small, the speed is slow, and the efficiency is low

Therefore, the present invention aims to solve the problems of low output of the above-mentioned single machine, small filtration pressure and long pressing time
