Special bidirectional liquid-outlet filter board for filter press

Abstract

The invention provides a special bidirectional liquid-outlet filter board for a filter press. The special filter board comprises a filter board, which contains an inner plate and a clamping plate. The inner plate is positioned inside the clamping plate. The structure is simple and the design is reasonable. Two sides of the clamping plate are both provided with a liquid outlet and a support frame. The liquid outlet is provided with a liquid outlet nozzle, which is provided with a control valve. Two sides of the bottom of the inner plate are both provided with liquid outlet holes. There are five liquid outlet holes, thus increasing liquid output capacity and enhancing liquid output speed of the whole unit. After deloading, liquid containing capacity of the filter board is greatly reduced, and lots of manpower and material resources are saved. Meanwhile, a mounting lug arranged on the inner plate, and a mounting groove arranged in an outer plate, are used in cooperation. Therefore, the clamping effect is better, the installation is convenient, and cost is lower. The product can better meet requirements of users.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a special filter plate for a two-way outlet hydraulic filter. Background technique [0002] Filter press is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries. It is a mechanical device that uses a special filter medium to exert a certain pressure on the object to make the liquid dialysis out. It plays the role of extracting the solid in the mixed liquid and realizing the separation of solid and liquid. It has the characteristics of stable performance, convenient operation, safety, and labor saving; the metal press barrel is processed by seamless steel pipe, and the plastic steel filter plate is precision cast, and it is resistant to high temperature, high pressure, and dura...

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a special filter plate for a two-way outlet hydraulic filter, which solves the problem that the existing filter press is one side outlet, so that the outlet volume is small; the outlet speed is slow; the filter cake also contains 28-35% liquid; and the filter cake is wet after getting off the machine, which increases the difficulty and time of cake dropping
