Filter cloth cleaning device for filter press

Abstract

The invention discloses a filter cloth cleaning device of a filter press. The filter cloth cleaning device comprises a cleaning tank, a driving wheel and a driven wheel which are respectively arranged above the cleaning tank, a positioning wheel arranged below a connecting line of an axial center of the driving wheel and an axial center of the driven wheel and just above a middle region of the cleaning tank, and a second brush roll set arranged at a position, which is close to the driven wheel, in the cleaning tank below one side of the positioning wheel, wherein the driving wheel, the driven wheel, the positioning wheel and the second brush roll set are sequentially connected by virtue of a filter cloth conveyor belt, the filter cloth conveyor belt is provided with a hollow filter cloth arranging frame and a filter cloth fixing device; nozzles are arranged at the front side and the rear side of the filter cloth conveyor belt and between the second brush roll set and the positioning wheel and are connected with a liquid outlet of a high-pressure pump, and a liquid inlet of the high-pressure pump is communicated with the cleaning tank. The filter cloth cleaning device has the characteristics of high filter cloth cleaning efficiency and good cleaning quality.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a filter cloth cleaning device for filter presses. Background technique [0002] Automatic filter press is a solid-liquid separation equipment used to realize various suspensions. It is widely used in petroleum, chemical industry, dyestuff, metallurgy, pharmaceutical, food, papermaking, coal washing and sewage treatment technology fields for solid-liquid separation. The use of an automatic filter press for solid-liquid separation is easy to use and has a good separation effect. The filter cloth is an important component of the automatic filter press, and its working quality directly affects the working status and efficiency of the automatic filter press. After a period of use, the filter cloth of the automatic filter press needs to be cleaned, but the cleaning of the filter cloth requires It takes up a lot of working time and directly affects the efficiency of the automat...

AI Technical Summary

Problems solved by technology

The filter cloth is an important component of the automatic filter press, and its working quality directly affects the working status and efficiency of the automatic filter press. After a period of use, the filter cloth of the automatic filter press needs to be cleaned, but the cleaning of the filter cloth requires It takes up a lot of working time and directly affects the efficiency of the automatic filter press

[0003] At present, most of the filter cloth cleaning devices of automatic filter presses use nozzles to flush the filter cloth with high-pressure water. Incomplete cleaning, low cleaning efficiency of filter cloth, high work intensity, and long time required for filter cloth cleaning

[0004] Publication number is the Chinese patent document of CNI004120B, discloses a kind of filter press, and its filter cloth cleaning device is movable nozzle, utilizes movable nozzle to clean each individual filter cloth, because the nozzle keeps moving during cleaning , so the hose connecting the nozzle will crack after a period of use, causing water leakage, reducing the water pressure of the nozzle, and affecting the cleaning effect. This cleaning method washes the filter cloth one by one, and it takes a long time to clean the filter cloth. The cloth cleaning device uses the impact force of the water sprayed by the high-pressure nozzle to wash away the dirt on the filter cloth. The cleaning efficiency of the filter cloth is low and the cleaning effect is limited.

And the cleaning method is single, and it is impossible to provide suitable cleaning solutions for filter cloths of filter presses in different environments

[0005] The Chinese patent document with the publication number 201470182U discloses a filter cloth cleaning device for a vertical filter press, which includes a box body, a nozzle, a water inlet pipe and a rubber tube, and a box for the technical problem that the filter cloth is not cleaned thoroughly and cannot be automatically controlled. Brushes, sensors and pinch valves are installed in the body. There is a filter cloth inlet on the top of the box and a filter cloth outlet on the bottom. The brushes are set at the inlet of the box and the middle of the box, and form a clamp for the filter cloth. , the nozzle is connected to the rubber tube and located on the front and back of the filter cloth, the sensor is set at the opening of the box, and the water inlet pipe is controlled by a pinch valve

This device realizes the automatic cleaning of the filter cloth, but since the brush is fixed, the friction between the filter cloth and the brush is sliding friction during cleaning, the friction is large, and the damage to the filter cloth is relatively large. While scraping off the stains on the surface of the filter cloth, part of the stains will be squeezed into the gaps of the filter cloth, which will increase the workload and difficulty of subsequent nozzle flushing of the filter cloth; the use of high-pressure nozzles to flush the filter cloth can only be impacted by water To resist the adhesion of stains to the filter cloth, the cleaning efficiency of the filter cloth is low and the cleaning effect is limited

[0006] To sum up, the existing filter cloth cleaning device of the filter press uses a brush to scrape off the stains on the surface of the filter cloth, and uses the impact force of the water sprayed by the high-pressure nozzle to release the technical solution of the stains from adhering to the filter cloth. The cleaning time of the filter cloth is long , low cleaning efficiency and large loss of filter cloth
