Gas-liquid telescoping, rapping and water flushing device for filter press and telescoping, rapping and water flushing method

Abstract

The invention relates to a gas-liquid extension vibrating and beating water washing device and an extension vibrating and beating water washing method for a filter press. The device comprises a stander frame of a washing trolley; extension brackets and handles of filter plates are directly connected; filter cloth respectively coated on outer surfaces of a plurality of the filter plates passes through respective filter cloth hanger rods; two ends of two hanger rods are mutually connected by cloth belts; two ends of each hanger rod are provided with hanging ring bolts respectively; the hanging ring bolts are connected with respective extension brackets respectively through extension springs; the gas-liquid extension vibrating and beating water washing device for the filter press is vertically positioned in the stander frame of the washing trolley, and the end part of a final-stage piston of a multi-stage hydraulic oil cylinder of the gas-liquid extension vibrating and beating water washing device for the filter press is connected with one end of a washing rod; the other end of the washing rod is connected with the tail end of a cylinder; a vibrating and beating head is connected with the cylinder and carris out upper vibrating, lower beating and bidirectional vibrating and beating on the hanger rods through the cylinder; and when a filter cloth extension mechanism pulls, the filter cloth of the filter plates pulls out certain angle through respective tension springs, and large vibration generated by vibrating and beating allows filter cakes attached to the surface of the filter cloth to fall off automatically.

Description

technical field [0001] The present invention relates to a kind of filter cake that is on the filter cloth of the filter plate of the filter press, through the varicose sheet of the filter press, unloading automatically, vibrating to force the material to be cleared, and water washing to clean the filter plate and filter cloth of the filter press. A flushing device and a method for flushing varicose rapping water belong to the field of filter press manufacturing. Background technique [0002] The applicant’s authorized announcement number is CN2928194Y, and the name is “Filter Press Filter Cloth Single Rod Cleaning Mechanism”. The bottom of both sides of the cleaning frame is equipped with manipulators and rollers, and is driven by the pull plate driving mechanism to move horizontally along the guide rail to pull the filter plate. Open, the upper ends of the two water inlet pipes are connected, and are sleeved on the outer cylinder of the hydraulic cylinder through the bracke...

AI Technical Summary

Problems solved by technology

[0004] The objective existence of the above-mentioned background technology is: firstly, because multiple groups of varicose racks are hingedly connected by rotating shafts, not only the structure is complicated, but also the replacement method is relatively complicated; Cloth flushing from top to bottom; third, there is a flushing mechanism in the function of the filter press, so there is no varicose and rapping mechanism, and the existing varicose rapping mechanism cannot solve the problem of downward flushing of the flushing rod because the suspenders are connected together. Problems; the fourth is that the automatic unloading and filter cloth cleaning during the filter cloth filtration process can not be solved at the same time to reduce the filter cloth reuse; the fifth is that the upper and lower spaces of the filter press are flushed with a single-stage oil cylinder, and the overall height is relatively high, increasing the height of the user's house Space and Construction Costs
