Plate-and-frame filter press convenient for discharging and control method

Abstract

The invention discloses a plate-and-frame filter press convenient for unloading and a control method, and relates to the technical field of plate-and-frame filter presses, the plate-and-frame filter press comprises a rack, a plurality of plate-and-frame filter pressing plates slidably connected with the rack are arranged between a fixed plate and an extrusion plate, at least one side surface of each plate-and-frame filter pressing plate is provided with a groove, and the groove is provided with a plurality of through holes; a sliding groove is formed in at least one side of the rack in the length direction, sliding blocks with the same number as the plate-and-frame filter pressing plates are slidably connected into the sliding groove, a supporting plate is arranged on the rack, the sliding blocks are connected through first electric telescopic rods, the sliding blocks and the supporting plate are connected through first electric telescopic rods, second electric telescopic rods are arranged on the sliding blocks, and the second electric telescopic rods are connected through second electric telescopic rods. The telescopic end of the second electric telescopic rod can extend into and out of one corresponding groove; a second electric telescopic rod is driven to extend into a groove in a corresponding plate-and-frame filter pressing plate, and a first electric telescopic rod is driven to drive the plate-and-frame filter pressing plates to be separated, so that the plate-and-frame filter pressing plates are conveniently and automatically separated, and a filter cake on the surface of a filter membrane falls off.

Description

technical field [0001] The invention relates to the technical field of plate and frame filter presses, in particular to a plate and frame filter press which is convenient for unloading and a control method. Background technique [0002] Filter press is a kind of equipment that separates materials from solid and liquid through pressure filtration. It is widely used in food, chemical, environmental protection and sewage treatment industries, especially for the separation of sticky and fine matter. It has unique advantages. The filter press is composed of multiple main boards and sub-frames to form a filter chamber, and the external pressure is used as the driving force for filtration. [0003] The plate and frame filter press is mainly composed of six parts: frame, plate and frame filter plate, driving mechanism, hydraulic station, pipeline system and PLC control system. Its working principle is as follows: First, after the system is powered on, the operator presses the press...

AI Technical Summary

Problems solved by technology

After the slurry fills the filter chamber, monitor the filtrate, and when it is found to be turbid, close the feed valve and continue to filter. The material enters each filter chamber from the feed hole on the plate and frame filter plate, and the solid particles are intercepted by the filter membrane. In the filter chamber, the liquid passes through the filter membrane and is discharged from the outlet hole. During the unloading process, the conventional plate and frame filter press often needs to manually move the position of the plate and frame filter plate to make the filter cake on the surface of the filter membrane fall. The operation is cumbersome, the degree of automation is low, and the labor force is large
