Description

Technical Field

[0001] This utility model relates to the field of air intake filtration devices, and in particular to an air intake filtration device for a magnetic levitation fan. Background Technology

[0002] Magnetic levitation fans, as a new type of high-efficiency, energy-saving, and stable-operating fan, have been widely used in many industrial and civilian applications. However, magnetic levitation fans have stringent requirements for the cleanliness of the intake air. During high-speed operation, if the intake air contains dust, particulate matter, or other impurities, the high-precision bearings and impellers inside the fan will experience accelerated wear, severely affecting the fan's service life and operational stability. Simultaneously, impurities can also cause duct blockage, reducing the fan's intake air volume and output air pressure, thereby decreasing the overall system efficiency. Therefore, it is necessary to filter the intake air of magnetic levitation fans.

[0003] A search revealed an integrated magnetic levitation high-speed blower air intake filtration device (publication number CN212429349U), comprising a filter element, a differential pressure sensor, an anemometer, a protective cover, a first winding unit, and a second winding unit. The protective cover is fixed to one end of the blower housing. The filter element is mounted on the protective cover, with one end connected to the first winding unit and the other end connected to the second winding unit. The differential pressure sensor and anemometer are both installed inside the blower housing. One of the two air pipes of the differential pressure sensor is connected to the inside of the blower housing, and the other is connected to the outside via a pipe. This integrated magnetic levitation high-speed blower air intake filtration device utilizes the winding unit to rotate the filter cotton roll, thereby replacing the filter cotton located in the filtration channel, ensuring the cleanliness of the filter cotton, and thus ensuring the air intake volume and airflow cleanliness.

[0004] Based on the aforementioned patent, two vibrators shake off the dust from the filter cotton, which is then collected in a dust collection box, allowing the filter cotton to be reused, improving its utilization rate, reducing the number of replacements, and lowering costs. However, the dust shaken off may not necessarily fall into the collection box below, and the dust may scatter everywhere. In response to this technical problem, this application proposes an air intake filtration device for a magnetic levitation fan. Utility Model Content

[0005] The purpose of this invention is to address the problem that dust dislodged by vibration may not necessarily fall into the collection box below, and may instead scatter everywhere. This invention proposes an air intake filtration device for a magnetic levitation fan. By having a cleaning brush move back and forth across the filter screen surface, the dust is cleaned, preventing dust from clogging the filter and maintaining its good air permeability. The cleaned dust is then collected into the collection box by an exhaust fan, preventing it from scattering around the equipment or in the working environment, and avoiding re-adhesion of dust onto the filter screen or pollution of the surrounding air.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air intake filtration device for a magnetic levitation fan, comprising an air intake pipe, a filter screen fixedly connected to the inner wall of the air intake pipe, a housing fixedly connected to the top of the air intake pipe, a motor fixedly connected to the inner wall of the housing, the motor being connected to a moving rod via a moving component, a first slider fixedly connected to the bottom of the moving rod, the outer wall of the first slider being slidably connected to the inner wall of the air intake pipe, the first slider being connected to a cleaning brush via a cleaning component, a dust collection hopper fixedly connected to the bottom of the inner wall of the air intake pipe, a dust collection component being provided at the bottom of the dust collection hopper, and an installation plate fixedly connected to the right end of the air intake pipe.

[0007] Furthermore, the moving component includes a rotating rod fixedly connected to the motor drive end, a control column fixedly connected to the rear end of the rotating rod, a control rod sleeved on the outer wall of the control column, the outer wall of the control rod slidably connected to the inner wall of the housing, and the top end of the moving rod fixedly connected to the bottom end of the control rod.

[0008] Furthermore, the cleaning assembly includes a rotating shaft rotatably connected to the front end of the first slider, the inner wall of the cleaning brush being fixedly connected to the outer wall of the rotating shaft, and the outer wall of the cleaning brush being close to the left end of the filter screen.

[0009] Furthermore, a gear is fixedly connected to the outer wall of the rotating shaft, and a toothed plate is meshed with the outer wall of the gear. The right end of the toothed plate is fixedly connected to the inner wall of the air inlet pipe.

[0010] Furthermore, a second slider is fixedly connected to the outer wall of the rotating shaft, and the outer wall of the second slider is slidably connected to the inner wall of the air inlet pipe.

[0011] Furthermore, the dust collection assembly includes a fixed box fixedly connected to the bottom end of the air inlet pipe, a connecting pipe fixedly connected to the left end of the fixed box, the other end of the connecting pipe fixedly connected to the bottom end of the dust collection hopper, a collection box installed on the inner wall of the fixed box, and an exhaust fan fixedly connected to the right end of the fixed box.

[0012] Furthermore, a limiting block is fixedly connected to the inner wall of the box, and the outer wall of the moving rod is slidably connected to the inner wall of the limiting block.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the control rod is driven by a motor to move up and down, which in turn drives the moving rod to move up and down, so that the cleaning brush moves back and forth on the surface of the filter screen to clean the dust on the surface of the filter screen, prevent dust from clogging the filter screen, maintain the good air permeability of the filter screen, and ensure the normal operation of the magnetic levitation fan air intake filtration equipment.

[0015] 2. In this utility model, by starting the exhaust fan, the dust collection bucket generates suction, which sucks the dust cleaned by the cleaning brush into the collection box, preventing the dust from drifting around the equipment or in the working environment, avoiding the dust from re-attaching to the filter screen or polluting the surrounding air, thereby effectively preventing secondary pollution and maintaining a good working environment and equipment operating conditions.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of an air intake filtration device for a magnetic levitation fan, comprising an air intake pipe 1, a filter screen 2 fixedly connected to the inner wall of the air intake pipe 1, and a housing 3 fixedly connected to the top of the air intake pipe 1. (Refer to...) Figure 4 A motor 4 is fixedly connected to the inner wall of the housing 3. A rotating rod 5 is fixedly connected to the drive end of the motor 4. A control column 6 is fixedly connected to the rear end of the rotating rod 5. A control rod 7 is sleeved on the outer wall of the control column 6. The outer wall of the control rod 7 is slidably connected to the inner wall of the housing 3. The top end of the moving rod 8 is fixedly connected to the bottom end of the control rod 7. The bottom end of the moving rod 8 is fixedly connected to the first slider 10. The outer wall of the first slider 10 is slidably connected to the inner wall of the air inlet pipe 1. The front end of the first slider 10 is rotatably connected to the rotating shaft 11. The inner wall of the cleaning brush 12 is fixedly connected to the outer wall of the rotating shaft 11. The outer wall of the cleaning brush 12 is close to the left end of the filter screen 2. A gear 14 is fixedly connected to the outer wall of the rotating shaft 11. A toothed plate 15 is meshed with the outer wall of the gear 14. The right end of the toothed plate 15 is fixedly connected to the inner wall of the air inlet pipe 1. A second slider 13 is fixedly connected to the outer wall of the rotating shaft 11. The outer wall of the second slider 13 is slidably connected to the inner wall of the air inlet pipe 1.

[0025] Specifically, the motor 4 and the exhaust fan 20 are connected to the magnetic levitation fan via wires and controlled by the controller on the magnetic levitation fan. When the motor 4 drives the rotating rod 5 to rotate, the rotating rod 5 will drive the control column 6 to rotate. The control column 6 will slide and rotate in the groove opened in the inner wall of the control rod 7, causing the control rod 7 to move up and down. This allows the rotating shaft 11 to move up and down. When the rotating shaft 11 moves, the first slider 10 and the second slider 13 on the front and rear sides will slide on the inner wall of the air inlet pipe 1 to support the rotating shaft 11 and enable it to move stably.

[0026] Reference Figure 5 A dust collection hopper 16 is fixedly connected to the bottom of the inner wall of the air inlet pipe 1. A fixed box 18 is fixedly connected to the bottom of the air inlet pipe 1. A connecting pipe 17 is fixedly connected to the left end of the fixed box 18. The other end of the connecting pipe 17 is fixedly connected to the bottom of the dust collection hopper 16. A collection box 19 is installed on the inner wall of the fixed box 18. An exhaust fan 20 is fixedly connected to the right end of the fixed box 18. A limit block 9 is fixedly connected to the inner wall of the box body 3. The outer wall of the moving rod 8 is slidably connected to the inner wall of the limit block 9. An installation plate 21 is fixedly connected to the right end of the air inlet pipe 1.

[0027] Specifically, a dustproof net is installed at the connection between the exhaust fan 20 and the fixed box 18 to prevent dust from entering the exhaust fan 20 from the collection box 19. The collection box 19 can be taken out from the fixed box 18. After a certain amount of dust is collected, the collection box 19 can be taken out from the fixed box 18 through the handle at the front end of the collection box 19 to clean the dust collected inside.

[0028] Working principle: During use, the air inlet pipe 1 is installed at the air inlet of the magnetic levitation fan via the mounting plate 21. Over time, dust accumulates on the filter screen 2 inside the air inlet pipe 1, causing blockage and affecting ventilation. At this point, the motor 4 is started. The motor 4 drives the rotating rod 5 to rotate, which in turn drives the control column 6 to rotate, causing the control rod 7 to move up and down. The control rod 7 then drives the moving rod 8 to move up and down, which in turn drives the first slider 10 to move back and forth, thereby moving the rotating shaft 11. The rotating shaft 11 then drives the cleaning brush 12 to clean the filter... As the screen 2 moves, the rotating shaft 11 moves, which in turn drives the gear 14 to move, causing the gear 14 to move on the toothed plate 15 and rotate. The gear 14 then drives the cleaning brush 12 to rotate through the rotating shaft 11, thereby cleaning the dust off the screen 2. At the same time, the exhaust fan 20 is activated, which generates suction in the dust collection hopper 16 through the connecting pipe 17, thereby sucking the dust cleaned by the cleaning brush 12 into the dust collection hopper 16. The dust then enters the collection box 19 along the connecting pipe 17, preventing dust from spreading around the equipment or in the working environment.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
