These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Refer to Figure 1 - Figure 4As shown in the figure, the present utility model provides a technical solution: an exhaust air filtering device, which includes a device body 1. A hollow groove 2 is provided inside the device body 1. Mounting frames 3 are installed on both sides of the device body 1. Mounting holes 4 are provided on the surface of the mounting frames 3. The number of the mounting holes 4 is several and they are evenly distributed on the surface of the mounting frames 3. A hinge 5 is installed at one end of the device body 1. The number of the hinges 5 is three and they are evenly distributed at one end of the device body 1. A cover plate 6 is installed on the surface of the hinge 5. A partition plate 7 is fixedly connected to the inner cavity of the device body 1. A support plate 8 is arranged in the inner cavity of the device body 1. When the filtering device is used for a long time, the filter plate 11 inside the filtering device may be blocked and needs to be cleaned or disassembled and replaced. At this time, the staff rotates the fixing bolt 10, so that the fixing bolt 10 gradually disengages from the threaded hole 9 and the inner cavity of the device body 1 through threaded connection. At this time, the staff can pull the cover plate 6, so that the cover plate 6 rotates and opens through the hinge 5. Then the staff pulls the mounting plate 12 outwards, so that the mounting plate 12 drives the mounting frame 13 and the filter plate 11 to displace outwards. Through the setting of the above structure, it is convenient for the staff to disassemble the filter plate 11 conveniently, preventing the inside of the filter plate 11 from being blocked during long-term use and affecting the use effect of the filtering device.

[0022] Referring to Figure 2 As shown in the figure, in this embodiment: a threaded hole 9 is provided inside the cover plate 6, and a fixing bolt 10 is connected to the inner cavity of the threaded hole 9 through threaded connection. Through the setting of the threaded hole 9 and the fixing bolt 10, the cover plate 6 can be effectively limited and fixed, and at the same time, it is convenient to open the cover plate 6.

[0023] Referring to Figure 3 and Figure 4 As shown in the figure, in this embodiment: a filter plate 11 is installed in the inner cavity of the device body 1. The material of the filter plate 11 can be glass fiber. Through the setting of the filter plate 11, the glass fiber has the characteristics of uniform fiber distribution, large dust capacity, small resistance, high strength, etc.

[0028] Working principle: When the filtering device is used for a long time, the filter plate 11 in the inner cavity of the filtering device may be blocked and needs to be cleaned or disassembled and replaced. At this time, the staff rotates the fixing bolt 10, so that the fixing bolt 10 gradually disengages from the threaded hole 9 and the inner cavity of the device body 1 through threaded connection. At this time, the staff can pull the cover plate 6, so that the cover plate 6 rotates and opens through the hinge 5. Subsequently, the staff pulls the mounting plate 12 outwards, so that the mounting plate 12 drives the mounting frame 13 and the filter plate 11 to displace outwards. Through the arrangement of the above structure, it is convenient for the staff to disassemble the filter plate 11 conveniently, preventing the inside of the filter plate 11 from being blocked after long-term use and affecting the use effect of the filtering device.
