A continuous plate drawing system for a filter press

Abstract

The invention relates to a continuous plate pulling system of a filter press in the field of sludge treatment industrial equipment manufacture.The continuous plate pulling system comprises a thrust plate, a pressing plate and a control system, wherein the thrust plate and the pressing plate are arranged in pairs in a matched mode, and several filter plates are arranged between the thrust plate and the pressing plate.Plate pulling mechanisms composed of plate pulling hooks, chains, driving motors, redirection pressing plates and return baffles are arranged at the front-back horizontal positions of the outer portions of the thrust plate, the filter plates and the pressing plate.The number of the filter plates is from 10 to 120.The filter plates are connected through connecting lines.The plates are pulled continuously, filter cakes are unloaded continuously, the plate pulling time is shortened, efficiency is improved in a multiplied mode, there is enough time for each filter plate to unload the filter cakes, and the problem that the filter cakes are scattered on the ground and pollute the environment is solved; the two plate pulling mechanisms are adopted for cooperative operation, and therefore the problems that when the plate pulling hooks pass by the filter plates which are closed, the former closed filter plate may be pulled, consequently, the plate pulling effect is affected, and work efficiency is lowered are solved.The continuous plate pulling system is simple in structure, convenient to maintain and easy to use and popularize.

Description

Technical field [0001] The invention relates to the manufacturing field of industrial equipment for papermaking, brewing and sludge treatment, and specifically refers to a continuous drawing plate system of a filter press used in a plate and frame filter press, a chamber filter press and a diaphragm filter press. Background technique [0002] In traditional papermaking, brewing, sludge treatment and other related industries, materials with high water content are dehydrated, and most of them use solid-liquid separation methods, mainly using centrifugal dehydrators, belt filter presses, plate and frame filter presses, and vacuum Filtering equipment such as filter presses filter solids out of the liquid to achieve the purpose of solid-liquid separation. [0003] At present, the existing filter presses are mainly ordinary filter presses and automatic pull plate filter presses. After each press filter is completed, the ordinary filter presses need to manually remove a large number of he...

AI Technical Summary

Problems solved by technology

The disadvantage is that every time the plate is pulled, all the filter plates are pulled apart at once, which requires a lot of force to pull apart, so only hydraulic cylinders and piston rods can be used, which is slow and consumes a lot of energy; after all the filter plates are pulled apart, it takes up The space is large, so in order to control the space occupied by the equipment, the design of the number of filter plates is greatly limited. Fewer filter plates means lower production capacity. The same production capacity requires more filter presses, which virtually increases investment and site occupancy.

Moreover, a pull plate type filter press (CN 2817948 Y) has a complex structure, many moving parts, and difficult maintenance
