Filter cloth cleaning device

Abstract

The invention relates to a filtering cloth cleaning device which is suitable for various belt filters and vertical frame pressure filters used for separating solids and liquids, belonging to the filtering cloth cleaning technology field. The filtering cloth cleaning device comprises a cleaning hopper 3, and a direction-guiding roller 4 used for guiding filtering cloth 2 linked with a driving roller 1 is arranged in the cleaning hopper 3, and the filtering cloth 2 is directly or indirectly driven by the driving roller 2 to turn continuously, and the direction-guiding roller 4 guides and supports the filtering cloth. An ultrasonic cleaning device 5, a brushing roller 6 and at least one water cleaning device are arranged correspondingly to a moving plane of the filtering cloth 2. Three cleaning methods all can be applied separately on line, i.e. the cleaning to the equipment can be realized without the need of stopping the equipment. The filtering cloth cleaning device of the invention can improve the prior art just from the designing idea, and the device not only can satisfy production requirement, but also can improve the structure of the whole machine, reduce production cost and prolong the service life of the filtering cloth.

Description

1. Technical field [0001] The invention relates to a filter cloth cleaning device, which is suitable for a belt filter and a vertical plate and frame filter press for separating various solids and liquids, and belongs to the technical field of filter cloth cleaning devices. 2. Background technology [0002] Belt filter and vertical plate and frame filter press are filtration equipment used for solid-liquid separation of various materials in mining, chemical, food, environmental protection and other fields. During the filtration process, some fine and sticky materials will adhere to the surface of the filter cloth or in the filter holes. After the filter cake is unloaded by the scraper, etc., it is cleaned. During this process, the water pipe nozzle is used to spray, and the effect is general, especially for fine particles. The material cannot fall off completely, thereby blocking the filter cloth and the nozzle of the water pipe, resulting in a decrease in the filtration eff...

AI Technical Summary

Problems solved by technology

[0004] Higher requirements for cleaning water quality, complex structure of water pipe nozzles and easy blockage, regular disassembly and maintenance are required, increasing maintenance costs and use costs

[0005] For materials with fine particle size and high viscosity to clog the filter cloth, it is not easy to clean and affect the working efficiency of the equipment

[0006] If the filter cloth is seriously clogged, it needs to be shut down regularly for cleaning, and even if the filter cloth is stopped for cleaning for a long time, it is difficult to restore the use effect of the filter cloth, and the replacement of the filter cloth will increase the cost of use.
