Horizontal pressure filter

Abstract

The invention provides a horizontal, full-automatic plate-frame type filter press, which adopts a double hydraulic cylinder to open the plate frame and utilizes a steadying bar fixed on a movable end to jack up a bearing bar hanging a filter cloth at the same time; after a filter cake is unloaded, a shower nozzle of a shower holder on the top of a bracket is used for spraying the water for washing all the filter cloths; the method adopts two cylinders to decrease pressure stroke, to reduce the cylinder volume and overcome the problems of uneven stress on the plate frame and non-tight sealing; by utilizing the movement of the hydraulic cylinder to hoist the filter cloth, the equipment is saved; by utilizing a plurality of shower nozzles to wash all the filter cloths simultaneously, a cleaning process is accelerated; by utilizing a supporting frame structure, the filter cloth can be replaced conveniently; by adopting a steel wire rope to control the supporting frame, the installation and the adjustment are very easy and convenient; the method has the advantages of simple structure, material saving and time saving, and fully utilizes a basic motive force to finish the entire pressing process without manual intervention, thereby improving handling capacity.

Description

technical field [0001] The invention relates to a filter press, in particular to a horizontal fully automatic filter press used for solid-liquid separation in industries such as smelting, chemical industry and environmental protection. Background technique [0002] In some places where solid-liquid separation is required, such as chemical industry, metallurgy, medicine and food, the horizontal filter press currently used uses a single hydraulic cylinder to squeeze multiple side-by-side plates and frames together, forming a filter chamber between the plates and frames. There is a filter cloth in the middle, and then inject slurry into each filter chamber. After the filter residue is full, use high-pressure water or high-pressure air to dry the filter residue in the plate frame to recover the filtrate or filter residue. This process also includes unloading And cleaning filter cloth. [0003] However, there are many problems in the horizontal filter press at present, such as s...

AI Technical Summary

Problems solved by technology

The filter plates of the filter press are connected by hinges, and can only passively wait for the previous plate frame to pull the next plate frame, which still has insufficient time and efficiency, and it is wasteful to add two more oil cylinders just to open the plate frame Increased power and increased unnecessary costs, did not make the best use of everything
