Description

Technical Field

[0001] The utility model relates to a filter cloth cleaning device, in particular to a compressed air-water mixing cleaning device. Background Art

[0002] A rubber belt vacuum filter is a highly efficient solid-liquid separation device. During operation, an endless rubber belt acts as a transmission mechanism, driving the filter cloth to form a continuous filtration zone. The slurry is evenly distributed on the moving filter cloth by the feed device. The negative pressure generated by the vacuum pump allows the filtrate to pass through the filter medium and enter the vacuum system, while solid particles are trapped on the filter cloth to form a filter cake. However, for materials with high viscosity and strong adsorption properties, a large amount of residual material may be adsorbed on the filter cloth during the discharge process, affecting the vacuum level of the equipment, shortening the service life of the filter cloth, and increasing maintenance and operating costs.

The nozzle can move linearly to clean different locations, while a cleaning brush is provided to sweep the filter cloth for cleaning. However, this solution consumes a large amount of water and requires water collection, and the cleaning brush may also damage the filter cloth. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1 To the attached Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] A compressed air-water mixing cleaning device can be fixedly mounted on a vacuum filter frame via a base 40. The device comprises an air intake assembly 10, an air outlet assembly 20, and a rotating assembly 30. Compressed air enters through the air intake assembly 10 and is blown out of the air outlet assembly 20. During this process, the rotating assembly 30 drives the cleaning device to rotate, cleaning the filter cloth through backflushing. Specifically, the air intake assembly 10 includes an air intake pipe 11, and the air outlet assembly 20 includes a drum 21 and an air outlet 22 disposed on the sidewall of the drum 21. The air intake pipe 11 extends into the interior of the drum 21, and the rotating assembly 30 is capable of driving the drum 21 to rotate about its axis.

[0024] The air intake assembly 10 also includes a static head 12, a dynamic head 13, and an intake manifold 14. A wear-resistant plate 15 is installed between the static head 12 and the dynamic head 13 to reduce wear and increase their service life. The air intake pipe 11 is connected to the static head 12. The intake manifold 14 is connected to the dynamic head 13 at one end and extends into the interior of the drum 21 at the other end. The dynamic head 13 and the intake manifold 14 are capable of rotating with the drum 21. Compressed air enters the air inlet of the air intake pipe 11, passes through the static head 12, the wear-resistant plate 15, the dynamic head 13, and the intake manifold 14 in sequence, and finally enters the interior of the drum 21. There are multiple intake manifolds 14, evenly distributed around the axis of the drum 21. In one embodiment, there are twelve intake manifolds 14. To further clean the filter cloth, a water inlet pipe 16 is installed in the air intake pipe 11. High-pressure water and compressed air work together to efficiently clean the filter cloth.

[0025] The drum 21 is provided with a plurality of evenly spaced guide grooves 23 along its axial direction. A guide rib 24 is formed between two guide grooves 23. The air outlet 22 is provided between the two guide ribs 24. The air outlet 22 extends into the drum 21 and communicates with the air intake branch pipe 14.

[0026] To increase the cleaning area, in one embodiment, the guide ribs 24 include first and second ribs 25, 26, spaced apart from each other. The first ribs 25 are provided with a plurality of ventilation slots 27. Each first rib 25 includes two ribs, one located on either side of the air outlet 22. Thus, the air outlet 22, the first ribs 25 on either side of the air outlet 22, the second ribs 26 outside the two first ribs 25, and the guide slots 23 therebetween collectively form a cleaning area. Compressed air is blown out of the air outlet 22, passing through the guide slots 23 and ventilation slots 27 to fill the entire cleaning area.

[0027] The rotating assembly 30 includes a rotating shaft 31 and a driving device 32 for driving the rotating shaft 31 to rotate. The rotating shaft 31 drives the drum 21 to rotate synchronously with it. The speed of the drum 21 is the same as the moving speed of the filter cloth 60. The driving device 32 can be a common driving device such as a motor.

[0028] There are two bases 40 , namely a first base 41 and a second base 42 . The first base 41 is rotatably connected to the movable head 13 via a slewing bearing, and the second base 42 is also rotatably connected to the rotating shaft 31 via a bearing.

[0029] To further stabilize the relative motion between the static head 12 and the dynamic head 13, in one embodiment, a compression spring assembly 50 is disposed between the first base 41 and the static head 12. The compression spring assembly 50 includes a guide rod 51 and a spring seat 52 fixed to the static head 12. One end of the guide rod 51 is connected to the first base 41, and the other end passes through the spring seat 52. A spring 53 is disposed between the guide rod 51 and the spring seat 52.

[0030] Taking the example of 12 intake branch pipes 14, the working process of the cleaning device of the present invention is as follows:

[0031] There are 12 intake manifolds 14, and the movable head 13 and wear-resistant plate 15 are provided with a corresponding number of holes connecting to them. Correspondingly, the drum 21 is provided with 12 air outlets 22 that are connected to the intake manifolds 14. During use, compressed gas enters through the air inlet of the intake manifold 11. Because the movable head 13, the intake manifolds 14, and the drum 21 rotate synchronously under the drive of the rotating assembly 30, the compressed air passes through the static head 12 and the wear-resistant plate 15, then enters each hole of the movable head 13 in sequence, and then passes through each intake manifold 14 in sequence. Finally, it is discharged from the corresponding air outlet 22 of each intake manifold 14, filling the entire cleaning area. The filter cloth 60 is in contact with the cleaning area, and because the rotation speed of the drum 21 is the same as the movement speed of the filter cloth 60, the filter cloth is cleaned.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
