Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an automatic cleaning filter. Background Technology

[0002] A filter is a device or apparatus used to separate different components in a mixture.

[0003] In existing technologies, filters are widely used in water treatment, air purification, chemical, food, and pharmaceutical fields to remove unwanted substances, thereby obtaining purer products or meeting specific process requirements. They separate impurities in the medium through physical barriers, adsorption, or biological processes. Mechanical filtration is the most common form, which uses filter screens, porous materials, etc. to trap solid particles.

[0004] However, after prolonged use, it was found that a large amount of impurities were adsorbed on the stainless steel filter cartridge wall, causing blockage and reducing the filter's operating efficiency.

[0005] Based on this, the present invention designs an automatic cleaning filter to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic cleaning filter.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic cleaning filter includes a filter body, a cover plate, a blower, and a fiber wall, and also includes a cleaning drive assembly and a filter cleaning assembly;

[0009] The cover plate is connected to the upper surface of the filter body, the blower is fixedly connected to the outer surface of the filter body, and the fiber wall is fixedly disposed on the inner wall of the filter body;

[0010] The inner surface of the cover plate is equipped with a cleaning drive assembly that can drive the cleaning of the inner wall of the filter body.

[0011] The filter body is equipped with a filter cleaning component that can clean the inner wall of the filter body.

[0012] The cleaning drive assembly and the filter cleaning assembly are connected. The filter cleaning assembly is located in the middle of the cleaning drive assembly. The length of the cleaning drive assembly is the same as the internal depth of the filter body.

[0013] The filter cleaning assembly includes a cleaning component and a positioning component, which are connected. The cleaning component is located outside the positioning component and is closer to the inner wall of the filter body than the positioning component.

[0014] Furthermore, an air inlet pipe, a flushing pipe, and an air outlet pipe are fixed on the outer arc-shaped surface of the filter body. The air inlet pipe and the flushing pipe are symmetrically distributed on the outer surface of the filter body near the upper end. The air outlet pipe is located on the outer surface of the filter body near the lower end. A drain pipe is fixed on the bottom surface of the filter body.

[0015] Furthermore, the cleaning drive assembly includes an annular block, a screw, a toothed block, a rotating sleeve, a guide rod, a square block, a motor, and a gear. The motor is fixedly mounted on the upper surface of the cover plate, and the gear is fixedly connected to the output end of the motor. The gear is located on the inner surface of the cover plate. The screw is fixedly mounted on the inner center surface of the cover plate. Two sets of annular blocks are fixedly mounted on the outer surfaces of the screw near both ends. Two sets of rotating sleeves are rotatably mounted on the outer surfaces of the screw near both ends. The two ends of the guide rod are respectively fixed to the ends of the two sets of rotating sleeves. The toothed block is fixedly mounted on the outer surface of the rotating sleeve near the upper end of the screw. The square block is fixedly mounted on the bottom surface of the inner wall of the filter body.

[0016] Furthermore, the toothed block is meshed with the gear, the inner wall of the rotating sleeve is provided with an annular groove, the outer surface of the annular block is in contact with the inner wall of the annular groove and is rotatably connected, and the lower end surface of the screw is provided with a square groove, the square groove is in contact with the square block and is slidably connected.

[0017] Furthermore, the cleaning assembly includes a brush ring and a support ring, the support ring being connected to the outer surface of the screw, the brush ring being slidably disposed on the outer arcuate surface of the support ring, and the brush ring and the support ring having the same height.

[0018] Furthermore, a threaded hole is provided at the center of the support ring, the screw is threadedly connected to the threaded hole, a through hole is provided on the upper surface of the support plate of the support ring, and the guide rod is slidably connected to the through hole.

[0019] Furthermore, the positioning component includes a positioning block, a rotating ring, a clamping block, a spring, and a spring damper. Multiple sets of the positioning blocks are circumferentially fixedly distributed on the inner surface of the brush ring. The rotating ring is rotatably mounted on the inner wall of the support ring. The lower end of the spring is fixedly mounted on the upper surface of the rotating ring. The clamping block is fixedly mounted on the upper end of the spring. The spring damper is fixedly mounted inside the spring.

[0020] Furthermore, the outer arc-shaped surface of the support ring is provided with a first groove, a second groove, and a rotating ring groove, and the three are connected. The rotating ring is in contact with the rotating ring groove for rotational connection, and the clamping block is in contact with the first groove and the second groove for sliding connection.

[0021] Compared with the prior art, the advantages of this utility model are as follows: 1. The blower draws air into the filter body. The air particles drawn in by the blower will undergo random Brownian motion inside the filter body, causing the particles to gradually approach the fiber wall inside the filter body and adsorb impurities through the fiber wall, thereby achieving the purpose of purifying the air.

[0022] 2. When it is necessary to clean the inner wall of the filter body, close the air inlet pipe and the air outlet pipe, then open the flushing pipe and inject cleaning agent into the filter body through the flushing pipe. Then start the motor and drive the rotating sleeve to rotate through the meshing of the tooth block and gear. The rotation of the rotating sleeve will drive the support ring to rotate through the cooperation of the guide rod and the through hole. The rotation of the support ring will drive the brush ring to rotate. The rotating brush ring will clean the fiber wall surface through the brushes on its outer surface. Since the upper end of the screw is fixed to the surface of the cover plate and cannot rotate, and the lower end of the screw cannot rotate through the cooperation of the square groove and the square block, it can be seen from the threaded cooperation that the support ring will move along the axis of the screw while rotating, so that the brush ring can clean the fiber wall surface at all heights, achieving complete cleaning.

[0023] 3. When the brush ring wears out after prolonged use and needs to be replaced, press the brush ring downwards. The downward movement of the brush ring will cause the clamping block to press downwards through the positioning block, thereby compressing the spring. Then rotate the brush ring to align the clamping block with the second groove. At this time, the upward movement limit of the positioning block disappears, and the brush ring can be pulled upwards to disengage the positioning block from the inner wall of the support ring. The brush ring can then be removed separately, thus disassembling the brush ring from the support ring and facilitating the replacement of the brush ring. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Example 1, please refer to the accompanying drawings in the specification. Figures 1-8 An automatic cleaning type filter includes a filter body 1, a cover plate 2, a blower 31 and a fiber wall 32. This filter is a medical air filter, mainly used to filter viruses and ultrafine particles <0.1 µm such as carbon soot in the air.

[0037] The cover plate 2 is connected to the upper surface of the filter body 1, the blower 31 is fixedly connected to the outer surface of the filter body 1, and the fiber wall 32 is fixedly disposed on the inner wall of the filter body 1.

[0038] A cleaning drive assembly 7 is installed on the inner surface of the cover plate 2, which can drive the cleaning of the inner wall of the filter body 1;

[0039] The filter body 1 is equipped with a filter cleaning component 8 that can clean the inner wall of the filter body 1.

[0040] The cleaning drive assembly 7 and the filter cleaning assembly 8 are connected. The filter cleaning assembly 8 is located in the middle of the cleaning drive assembly 7. The length of the cleaning drive assembly 7 is the same as the internal depth of the filter body 1.

[0041] The filter cleaning assembly 8 includes a cleaning component and a positioning component, which are connected. The cleaning component is located outside the positioning component and is closer to the inner wall of the filter body 1 than the positioning component.

[0042] Based on Embodiment 1, an air inlet pipe 3, a flushing pipe 4, and an air outlet pipe 5 are fixed on the outer arc-shaped surface of the filter body 1. The air inlet pipe 3 and the flushing pipe 4 are symmetrically distributed on the outer surface of the filter body 1 near the upper end. The air outlet pipe 5 is located on the outer surface of the filter body 1 near the lower end. A drain pipe 6 is fixed on the bottom surface of the filter body 1.

[0043] The cleaning drive assembly 7 includes annular block 9, screw 10, toothed block 12, rotating sleeve 13, guide rod 14, square block 28, motor 29, and gear 30. Motor 29 is fixedly mounted on the upper surface of cover plate 2. Gear 30 is fixedly connected to the output end of motor 29 and is located on the inner surface of cover plate 2. Screw 10 is fixedly mounted on the inner center surface of cover plate 2. Two sets of annular blocks 9 are fixedly mounted on the outer surfaces of screw 10 near both ends. Two sets of rotating sleeves 13 are rotatably mounted on the outer surfaces of screw 10 near both ends. The two ends of guide rod 14 are fixed to the ends of the two sets of rotating sleeves 13 respectively. Toothed block 12 is fixedly mounted on the outer surface of rotating sleeve 13 near the upper end of screw 10. Square block 28 is fixedly mounted on the bottom surface of the inner wall of filter body 1.

[0044] The toothed block 12 is meshed with the gear 30. The inner wall of the rotating sleeve 13 is provided with an annular groove 15. The outer surface of the annular block 9 is in contact with the inner wall of the annular groove 15 and is rotatably connected. The lower end surface of the screw 10 is provided with a square groove 11. The square groove 11 is in contact with the square block 28 and is slidably connected.

[0045] The cleaning assembly includes a brush ring 16 and a support ring 17. The support ring 17 is connected to the outer surface of the screw 10, and the brush ring 16 is slidably disposed on the outer arc-shaped surface of the support ring 17. The brush ring 16 and the support ring 17 have the same height.

[0046] A threaded hole 18 is provided at the center of the support ring 17. The screw 10 is threadedly connected to the threaded hole 18. A through hole 19 is provided on the upper surface of the support plate of the support ring 17. The guide rod 14 is slidably connected to the through hole 19.

[0047] The positioning assembly includes a positioning block 20, a rotating ring 21, a clamping block 24, a spring 25, and a spring damper 26. Multiple positioning blocks 20 are circumferentially fixedly distributed on the inner surface of the brush ring 16. The rotating ring 21 is rotatably mounted on the inner wall of the support ring 17. The lower end of the spring 25 is fixedly mounted on the upper surface of the rotating ring 21. The clamping block 24 is fixedly mounted on the upper end of the spring 25. The spring damper 26 is fixedly mounted inside the spring 25. Since vibration will occur during rotation, the spring damper 26 can suppress the oscillation when the spring 25 rebounds after absorbing shock.

[0048] The outer arc-shaped surface of the support ring 17 is provided with a first groove 22, a second groove 23 and a rotating ring groove 27, and the three are connected. The rotating ring 21 is in contact with the rotating ring groove 27 and is rotatably connected. The clamping block 24 is in contact with the first groove 22 and the second groove 23 and is slidably connected.

[0049] In actual use, the blower 31 draws air into the filter body 1. The air particles drawn in by the blower 31 will undergo random Brownian motion inside the filter body 1, causing the particles to gradually approach the fiber wall 32 inside the filter body 1. The impurities are then adsorbed by the fiber wall 32, thereby achieving the purpose of purifying the air.

[0050] When the inner wall of the filter body 1 needs to be cleaned, the air inlet pipe 3 and the air outlet pipe 5 are closed. Then, the flushing pipe 4 is opened and cleaning agent is injected into the filter body 1 through the flushing pipe 4. Then, the motor 29 is started and the rotating sleeve 13 is driven to rotate through the meshing of the tooth block 12 and the gear 30. The rotation of the rotating sleeve 13 will drive the support ring 17 to rotate through the cooperation of the guide rod 14 and the through hole 19. The rotation of the support ring 17 will drive the brush ring 16 to rotate. The rotating brush ring 16 will clean the surface of the fiber wall 32 through the brush on its outer surface. Since the upper end of the screw 10 is fixed to the surface of the cover plate 2 and cannot rotate, and the lower end of the screw 10 cannot rotate through the cooperation of the square groove 11 and the square block 28, it can be seen from the threaded connection that the support ring 17 will move along the axis of the screw 10 while rotating, so that the brush ring 16 can clean the surface of the fiber wall 32 at all heights, achieving complete cleaning.

[0051] When the brush ring 16 wears out after prolonged use and needs to be replaced, press the brush ring 16 downwards. The downward movement of the brush ring 16 will cause the clamping block 24 to be pressed downwards through the positioning block 20, thereby causing the spring 25 to contract. Then rotate the brush ring 16 to align the clamping block 24 with the second groove 23. At this time, the upward movement limit of the positioning block 20 disappears, and the brush ring 16 can be pulled upwards to disengage the positioning block 20 from the inner wall of the support ring 17. The brush ring 16 can then be removed separately, thereby disassembling the brush ring 16 from the support ring 17 and facilitating the replacement of the brush ring 16.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
