Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to a special air filtration device for the interior of cabinet equipment. Background Art

[0002] A cabinet is an independent or self-supporting casing used to house electrical or electronic equipment. It is not only a container for storing equipment but also has various protection and management functions. To ensure the stable operation of the equipment, the cabinet must dissipate heat, replacing the cold air outside the cabinet with the cold air inside the cabinet and at the same time discharging the hot air inside the cabinet to the outside. This large amount of air exchange will inevitably bring in a large amount of dust. If the dust accumulates inside the cabinet for a long time, it will adhere to the circuit board, affecting the heat dissipation effect of the equipment and even possibly causing the equipment to short-circuit or burn out. Installing an air filtration device at the ventilation inlet can effectively filter out the dust in the air and keep the interior of the cabinet clean. An air filtration device is a device that removes suspended particulate matter in the air through physical or chemical means.

[0003] After retrieval, a Chinese patent with the application number CN202120519947.9 discloses an air filtration device. When it is necessary to replace the chemical filter, the replacement of the bottom-mounted chemical filter is an extremely complex task. It is necessary to first remove the HEPA filter, which is extremely inconvenient to replace and is also likely to damage the filter paper inside the HEPA, directly affecting the efficiency of the HEPA. Therefore, by setting a buffer rack and installing the chemical filter on the top of the box, the installation and replacement of the chemical filter are simple and convenient, and the size of the chemical filter can be designed larger. Under the condition of the same air volume, the rotation speed of the fan can be reduced, the resistance of the chemical filter is also correspondingly reduced, the filter media in the chemical filter can better contact with the air flow, increasing the residence time of the air flow, improving the adsorption and filtration efficiency of the chemical filter, and at the same time reducing the energy consumption of the fan and the noise. The effects in multiple aspects greatly reduce the overall operation cost.

[0004] During the above air filtration process, it is convenient to improve the filtration efficiency, but it is likely to increase the filtration cost, thus having deficiencies. In the existing air filtration process, due to the filter screen being provided inside the filtration device, after a long time of use, the mesh holes are easily covered by the dust and impurities filtered out, making it difficult to clean the dust on the dust-blocking surface of the internal filter screen, resulting in difficult cleaning work, easily reducing the filtration effect of the filtration device, and easily affecting the air intake function of the air filtration device, which is not conducive to the heat dissipation of the cabinet.

The outside of the stabilizing block 9 is slidably connected inside the stabilizing groove 10. One end of the screw rod 2 is fixedly connected with a driven bevel gear 11. One side of the installation frame 1 is fixedly installed with a motor 12. The output end of the motor 12 is fixedly connected with a driving bevel gear 13. The driving bevel gear 13 and the driven bevel gear 11 are meshed with each other. The rotation of the screw rod 2 facilitates driving the movement of the moving plate 3. The protective shell 5 and the pushing block 6 are convenient for protecting and limiting the pushing spring 7 to prevent the deformation of the pushing spring 7. And the pushing spring 7 is arranged inside the protective shell 5, which is convenient for pushing the dust sweeping brush 8, making the dust sweeping brush 8 fit more closely with the filter screen surface.

[0035] As shown in the atta Figure 7 ched drawings, the inner wall of the installation frame 1 is provided with a second installation groove 15 and two first installation grooves 14. Two limiting grooves 25 are opened at the top of one side of the installation frame 1. The limiting grooves 25 are convenient for the clamping of the limiting blocks 21. The two second installation grooves 15 are convenient for installing the large-hole filter screen 16 and the medium-hole filter screen 17, and the first installation grooves 14 are convenient for installing the fine-hole filter screen 18.

[0036] As shown in the attached Figure 3 figure, a meshed filter screen 17 is slidably connected inside the first installation groove 14 at the rear side, and a fine-pored filter screen 18 is slidably connected inside the second installation groove 15. A connecting plate 19 is fixedly connected to the upper surfaces of the large-pored filter screen 16, the meshed filter screen 17, and the fine-pored filter screen 18.
