Description

Technical Field

[0001] This utility model relates to the field of cleanroom test bench technology, specifically to a cleanroom test bench air supply filter component. Background Technology

[0002] The clean bench consists of several major components, including the cabinet, fan, filter plate, and operating switch. During use, air is filtered through the primary filter plate, then pressed into the static pressure box by the centrifugal fan, and finally filtered through the high-efficiency filter before being blown out from the air outlet, forming a clean airflow. The clean airflow flows through the area to be purified at a uniform cross-sectional wind speed, carrying away the dust in the area and thus creating a high-cleanliness working environment.

[0003] When using a filter plate for primary filtration of dust and other debris in the air, the dust and debris will adhere to the surface of the filter plate. After prolonged use, the filter plate is prone to clogging due to the dust and debris, resulting in a decrease in air intake. Since the filter plate is installed on the top of the clean bench, the high installation position increases the risk of working at height when disassembling and cleaning the filter plate.

[0004] Therefore, there is an urgent need for a purification test bench air supply filter component to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a purification test bench air supply and filtration assembly, including a bench body, an air inlet provided on the top of the bench body, and a filtration assembly disposed on the bench body for primary filtration of the air inlet.

[0006] The filter assembly includes a filter frame fixedly connected to the side of the platform near the air inlet, a filter mesh slidably connected to the filter frame, and release components for releasing the filter mesh and rewinding components for rewinding the used filter mesh on opposite sides of the platform.

[0007] The release assembly includes two symmetrically arranged first fixing plates fixedly connected to one side of the platform, a release rod rotatably connected between the two first fixing plates, the filter cloth being rolled onto the release rod, and a first motor fixedly connected to one of the two first fixing plates, the output end of the first motor being connected to the release rod.

[0008] The winding assembly includes two symmetrically arranged second fixing plates fixedly connected to the side of the platform away from the release rod. A winding rod is rotatably connected between the two second fixing plates. The winding rod is provided with a limiting component for limiting the end of the filter cloth away from the release rod. A second motor is fixedly connected to one of the two second fixing plates, and the output end of the second motor is connected to the winding rod.

[0009] The limiting component includes an elongated hole formed on the side wall of the winding rod, a limiting plate is slidably connected to the elongated hole, and multiple springs are fixedly connected to the side wall of the elongated hole, with the other end of each spring connected to the limiting plate.

[0010] The platform is provided with a support assembly for supporting the filter cloth. The support assembly includes two symmetrically arranged support plates fixedly connected to two opposite side walls of the platform. A support rod is rotatably connected between two adjacent support plates, and the filter cloth is slidably connected to the support rod.

[0011] The platform is equipped with a protective component for protecting the unused filter cloth. The protective component includes a protective box that is detachably connected to the side of the platform near the release rod. A protective plate is snapped onto the side of the protective box near the filter frame, and the filter cloth is slidably connected to the protective plate.

[0018] 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.

[0019] Example 1

[0020] Please see Figures 1-3 The diagram shows a purification test bench air supply filter assembly, which includes a bench body 1, an air inlet on the top of the bench body 1, and a filter assembly disposed on the bench body 1 for primary filtration of the air inlet.

[0021] The filter assembly includes a filter frame 201 fixedly connected to the side of the platform 1 near the air inlet. The filter frame 201 is slidably connected to a filter mesh 202. On opposite sides of the platform 1, there are release components for releasing the filter mesh 202 and a winding component for winding up the used filter mesh 202.

[0022] It should be noted that the filter components not only perform primary filtration of dust and other impurities in the external air, but also facilitate the replacement of the filter mesh 202 by using the release and rewind components. The operation is simple and convenient, reducing manual intervention and thus reducing the risk of working at heights.

[0023] Please see Figure 2 The release assembly shown in the figure includes two symmetrically arranged first fixing plates 301 fixedly connected to one side of the platform 1, a release rod rotatably connected between the two first fixing plates 301, a filter cloth 202 rolled on the release rod, and a first motor 302 fixedly connected to one of the two first fixing plates 301, the output end of the first motor 302 being connected to the release rod.

[0024] It should be noted here that the release component setting facilitates the initial placement of the filter cloth 202 and its release during replacement.

[0025] Please see Figure 3 The winding assembly shown in the figure includes two symmetrically arranged second fixing plates 401 fixedly connected to the side of the platform 1 away from the release rod. A winding rod 402 is rotatably connected between the two second fixing plates 401. The winding rod 402 is provided with a limiting component for limiting the end of the filter cloth 202 away from the release rod. A second motor 403 is fixedly connected to one of the two second fixing plates 401. The output end of the second motor 403 is connected to the winding rod 402.

[0026] It should be noted here that the winding component facilitates the winding of the used filter cloth 202.

[0027] Please see Figure 3 The limiting component shown in the figure includes an elongated hole 501 opened on the side wall of the winding rod 402. The elongated hole 501 is slidably connected to a limiting plate 502. Multiple springs 503 are fixedly connected to the side wall of the elongated hole 501. The other end of each spring 503 is connected to the limiting plate 502.

[0028] It should be noted here that the limiting component is used to limit the winding end of the filter mesh 202, thereby facilitating the winding operation.

[0029] Working principle: When the purification test bench is in use, the release rod with the filter cloth 202 rolled up is first installed on the two first fixed plates 301. Then, one end of the filter cloth 202 is pulled so that one end of the filter cloth 202 passes through the support assembly, the filter frame 201 and the support assembly in sequence, and abuts against the side wall of the winding rod 402.

[0030] When one end of the filter mesh 202 abuts against the side wall of the winding rod 402, it is inserted into the elongated hole 501. Under the elastic action of multiple springs 503, the limiting plate 502 abuts against one end of the filter mesh 202, thus completing the installation of the filter mesh 202. After the filter mesh 202 is installed, the fan can be used to supply air. During the air supply process, the filter mesh 202 performs primary filtration of dust and other impurities in the outside air. Under the pressure of the fan, the air enters the static pressure box, and after being filtered by the high-efficiency filter, it is blown out from the air outlet to form a clean airflow. The clean airflow flows through the area to be purified at a uniform cross-sectional wind speed, carrying away the dust in the area, thus forming a high-cleanliness working environment.

[0031] In the process of using filter cloth 202 to perform primary filtration of external gas, after a long period of use, the filter position needs to be replaced. During the replacement of filter cloth 202, the first motor 302 and the second motor 403 are started simultaneously, thereby realizing the synchronous release and rewinding of filter cloth 202, thus completing the replacement of the filter position of filter cloth 202. The operation is simple and convenient, reducing manual intervention and thus reducing the risk of high-altitude operations.

[0032] Example 2

[0033] Please see Figure 2This embodiment further illustrates Example 1. The platform 1 in the figure is provided with a support assembly for supporting the filter cloth 202. The support assembly includes two support plates 601 that are fixedly connected to the two opposite side walls of the platform 1 and are symmetrically arranged. A support rod 602 is rotatably connected between two adjacent support plates 601. The filter cloth 202 is slidably connected to the support rod 602.

[0034] It should be noted here that the support components are used to support the sliding of the filter cloth 202, thereby ensuring the stability of the sliding of the filter cloth 202.

[0035] Example 3

[0036] Please see Figure 2 This embodiment is a further description of other embodiments. The platform 1 in the figure is provided with a protective component for protecting the unused filter cloth 202. The protective component includes a protective box 701 that is detachably connected to the side of the platform 1 near the release rod. A protective plate 702 is snapped onto the side of the protective box 701 near the filter frame 201. The filter cloth 202 is slidably connected to the protective plate 702.

[0037] It should be noted that the protective components are used to cover and protect the unused filter cloth 202, thereby maintaining the cleanliness of the filter cloth 202.
