Filter press capable of automatically clearing filter residues and use method

Abstract

The invention relates to the field of filter presses, in particular to a filter press capable of automatically clearing filter residues and a use method. The filter press capable of automatically clearing the filter residues comprises beams, an impeller, a keep plate, a thrust plate, separating mechanisms and a rack. The filter press capable of automatically clearing the filter residues and the use method have the advantages that after mixed liquid is filtered and an intercepted material is dehydrated to form filter cake, through screws, the keep plate can slide along installation grooves, then by means of the separating mechanisms, filter frames move along with the keep plate to separate the filter cake, the filter cake automatically falls, and is unloaded, in a separation process of thefilter frames, gears move along surfaces of rack boards, and respectively drive rotating shafts and rotating boards to rotate in the filter frames, by rotating the rotating boards constantly, filter clothes continuously expand and shrink under stress to form vibration, thus the filter cake, residues and the like which are hung on surfaces of the filter clothes in a stuck mode are shaken off, filtering effects of the filter clothes are guaranteed, the situation that workers waste time and energy while shoveling is avoided, and only the filter clothes are subjected to action, and are made to vibrate, and the filter frames and filter boards are not made to vibrate, so that the leakproofness between each filter frame and the corresponding filter board is not affected, and leakage of the mixedliquid is prevented.

Description

technical field [0001] The invention relates to the field of filter presses, in particular to a filter press for automatically cleaning filter residues and a use method thereof. Background technique [0002] The filter press is the filtration equipment in the solid-liquid separation machinery industry. The box filter plate is the main filter element of the filter press. When the filter press is filtering, the material is injected between the filter plates by the feed pump, and the filter plate is installed through the filter plate. The particles in the material retained by the filter cloth remain in the space between the filter plates, and the filtrate is discharged from the outlet pipe to dehydrate the retained material to form a filter cake. There are traditional technologies that are not considered comprehensively and have the following disadvantages: [0003] When the filter press feed filter is completed and the filter plate is opened to remove the filter cake, some fi...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a filter press for automatically cleaning filter residues and its use method to overcome the problem in the prior art that manually eradicating the filter cake stuck to the filter cloth of the filter plate takes time and effort and easily damages the filter cloth and increases the cost.
