Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to an integrated cleaning component in an automatic cleaning filter and a cleaning method thereof. Background Art

[0002] A filter is a device used to separate solids from liquids or gas mixtures. It is widely used in chemical, pharmaceutical, food, environmental protection and other fields. It uses physical, mechanical or chemical means to intercept solid particles in the mixture using filter media, thereby achieving solid-liquid or solid-gas separation.

[0003] In the above-mentioned filtering process, solid particles will be retained on the filter medium and its mounting frame, so they need to be cleaned regularly. The rotary filter in the prior art drives the central tube to rotate through a reducer, and the filter plate fixed on the central tube can be sprayed circumferentially by the nozzle, but its cleaning effect is still not thorough enough, and there is room for improvement.

[0004] In order to solve the above technical problems, the patent document with patent number 202221379858.X discloses a laminated brush structure of a rotary filter, including a central tube, on which a plurality of brush assemblies are tightly sleeved in sequence, each of the brush assemblies includes a first pressure ring, a brush, a second pressure ring and a filter plate, the first pressure ring and the second pressure ring are both sleeved on the central tube, the brush includes a connector and a brush body, the first pressure ring and the second pressure ring are respectively provided with a first positioning step and a second positioning step, the connector is simultaneously sleeved on the first positioning step and the second positioning step, the brush is sleeved on the central tube and contacts with the surface of the second pressure ring, the brush body is provided with bristles that can contact the filter plate, the end of the brush body protrudes from the filter plate setting, one end of the central tube is abutted against the brush assembly through a fixed block and an annular pressure plate, and the other end is abutted against the brush assembly through an annular pressure plate and a clamp.

[0005] When the above scheme is in use, one end of the central tube is connected to the reducer. The rotation of the reducer drives the filter material to rotate, and the brush rotates with the central tube. A workpiece that can abut the end of the brush is provided inside the filter cartridge. The position of the brush protruding from the filter plate is blocked by the workpiece welded to the inner wall of the filter cartridge so that it does not rotate. In this way, the filter plate rotates while the brush is fixed. When it rotates one circle, the filter plate contacts the brush throughout the entire circle, thereby achieving the cleaning of the filter plate. The cleaning effect is more thorough than that of the prior art.

[0006] However, the filter targets various solid particles, so various impurities will remain on the installation frame of the filter medium, and the cleaning mechanism of the above solution is only a single brush, which cannot meet the cleaning requirements of various types of impurities.

[0007] In addition, the brush in the above technical solution needs to be blocked by a workpiece welded to the inner wall of the filter cartridge to prevent it from rotating, thereby achieving relative movement between the filter plate and the brush and completing the cleaning action. The blocking of the workpiece will give the motor a reverse torque, which may cause damage to the motor shaft.

[0008] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0011] An integrated cleaning assembly in an automatic cleaning filter comprises a connecting portion and a cleaning portion connected to the connecting portion, wherein the connecting portion comprises a connecting ring, a center hole is provided in the middle of the connecting ring, a positioning ring is arranged in the center hole, and a plurality of key grooves are provided on the inner circumference of the positioning ring;

[0012] The cleaning part comprises a cleaning frame, on which a bristle assembly, a scraper assembly and a water spray assembly for completing different cleaning functions are respectively arranged.

[0013] The bristle assembly comprises a plurality of flexible bristles, the bottoms of which are respectively connected and fixed to the upper and lower surfaces of the cleaning frame to form a bristle area.

[0014] The scraper assembly comprises a hard scraper, and the hard scraper is arranged at the edge of the cleaning frame.

[0015] The water spray assembly includes a water spray pipe, which is arranged inside the cleaning frame and along the length direction of the cleaning frame. A water inlet is provided at the outer end of the cleaning frame, and the water inlet is connected to the internal flow channel of the water spray pipe. A plurality of water spray nozzles are opened along the outer surface of the water spray pipe, and the water spray nozzles are connected to the internal flow channel of the water spray pipe and are respectively distributed along the upper and lower surfaces of the cleaning frame.

[0016] The flexible bristles are made of flexible material, the hard scraper is made of hard material, and the height of the flexible bristles is greater than the height of the hard scraper.

[0017] The connecting part is connected to the cleaning part through an integrated structure, and the outer circumferential surface of the positioning ring and the inner circumferential surface of the connecting ring are clearance-matched.

[0018] The width of the washing frame gradually decreases from the inside to the outside.

[0019] In summary, the utility model has the following beneficial effects:

[0020] By arranging a plurality of cleaning structures with different functions on the support, different types of impurities on the filter assembly can be cleaned.

[0021] The cleaning component is movably connected to the central tube through the positioning ring, and the filter component is fixedly connected to the central tube, so the filter component will move relative to the cleaning component to complete the cleaning action. In the above process, since the positioning ring and the connecting ring of the integrated cleaning component are clearance-fitted, no torque opposite to the rotation direction of the motor is generated, thereby ensuring the service life of the motor.

[0031] The water spray assembly 24 includes a water spray pipe 241, which is arranged inside the cleaning frame 21. The water spray pipe 241 is arranged along the length direction of the cleaning frame 21. A water inlet 242 is provided at the outer end of the cleaning frame 21. The water inlet 242 is connected to the internal flow channel of the water spray pipe 241. A plurality of water spray nozzles 243 are opened along the outer surface of the water spray pipe 241. The water spray nozzles 243 are connected to the internal flow channel of the water spray pipe 241 and are distributed along the upper and lower surfaces of the cleaning frame 21 respectively.

[0032] The flexible bristles 221 are made of flexible material, and the hard scraper blade 231 is made of hard material. The height of the flexible bristles 221 is greater than the height of the hard scraper blade 231 .

[0033] The connecting part 1 is connected to the cleaning part 2 through an integrated structure, and the outer circumferential surface of the positioning ring 13 and the inner circumferential surface of the connecting ring 11 are clearance-fitted.

[0034] The width of the washing frame 21 gradually decreases from the inside to the outside.

[0035] A method for cleaning an integrated cleaning component in an automatic cleaning filter comprises the following steps:

[0036] 1) The connecting part 1 and the cleaning part 2 of the integrated cleaning assembly are mounted on the central tube 3 of the automatic cleaning filter through the key groove 14 of the positioning ring 13 and the key sleeve of the central tube 3, and the filter assembly 4 is also fixed on the central tube 3;

[0037] 2) Start the motor, the motor drives the central tube 3 to rotate, and drives the integrated cleaning assembly and the filter assembly 4 on the central tube 3 to rotate. Since the positioning ring 13 and the connecting ring 11 of the integrated cleaning assembly are clearance-matched, and the filter assembly 4 is fixedly connected to the central tube 3, the filter assembly 4 will move relative to the connecting portion 1 and the cleaning portion 2;
