[0017] 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of an easily detachable structure for dust removal and detection in a high-efficiency exhaust filtration device, comprising a filter box 1. The main internal structure of the filter box 1 adopts a "scanning method" (such as laser particle counter scanning), which releases standardized aerosol upstream of the filter and uses a particle counter to simultaneously detect the upstream and downstream particle concentrations to calculate the filtration efficiency. In some scenarios, a "counting method" or "weight method" can be used for verification. An exhaust port is provided inside the filter box 1 to discharge the filtered gas. A connecting frame 2 is fixedly connected to the side wall of the filter box 1, which connects the filter box 1 to different exhaust ports. A collection frame 13 is provided at the bottom of the filter box 1 to collect impurities inside the filter box 1. A discharge port is opened at the bottom of the filter box 1, and an inlet port with a size adapted to the discharge port is opened at the top of the collection frame 13. The discharge port and the inlet port achieve the effect of discharging and collecting impurities. Furthermore, the inner wall of the connecting frame 2 is elastically connected to a fixing plate 12 via a connecting spring 11. When the fixing plate 12 is pushed, it compresses the connecting spring 11, causing the connecting spring 11 to deform. When resetting, the rebound of the connecting spring 11 drives the fixing plate 12 to slide and reset. A connecting rod 9 is slidably connected inside the connecting frame 2. A sliding hole adapted to the size of the connecting rod 9 is opened inside the connecting frame 2. Multiple equal-sized and equidistantly distributed adjustment slots are opened inside the connecting rod 9. A clamping plate 10 is fixedly connected to the end of the connecting rod 9. The movement of the connecting rod 9 drives the clamping plate 10 to slide and adjust. An adjustment component 8 is provided inside the connecting frame 2. Furthermore, a filter screen 3 is fixedly connected inside the filter box 1. The filter screen 3 is used to filter particulate matter and impurities in the gas. A servo motor 4 is fixedly connected to the side wall of the filter screen 3. A rotating rod 5 is fixedly connected to the output end of the servo motor 4. The servo motor 4 drives the rotating rod 5 to rotate. A cleaning plate 6 is fixedly connected to the end of the rotating rod 5. A cleaning pad is provided on the side wall of the cleaning plate 6. The side wall of the cleaning pad is in contact with the side wall of the filter screen 3. During the rotation of the cleaning pad, it cleans the impurities remaining on the side wall of the cleaning plate 6, thereby improving the filtration efficiency of the filter screen 3. A shielding mechanism 7 is provided inside the filter box 1.

[0019] Reference Figures 2-3The shielding mechanism 7 includes a shielding plate 71, which is slidably connected inside the filter box 1. The shielding plate 71 is arc-shaped, and the filter box 1 has an arc-shaped groove that matches the size of the shielding plate 71. A push block 72 is fixedly connected to the top of the shielding plate 71. The side wall of the push block 72 is inclined. The side wall of the cleaning plate 6 contacts the side wall of the push block 72. The end of the cleaning plate 6 pushes the push block 72 during rotation. As the cleaning plate 6 continues to rotate, it gradually releases the push on the push block 72. The side wall of the shielding plate 71 is elastically connected to the inner side wall of the filter box 1 through a return spring 73. When the shielding plate 71 is pushed, it squeezes the return spring 73, causing the return spring 73 to deform. When resetting, the rebound of the return spring 73 drives the shielding plate 71 to slide and reset.

[0020] Reference Figures 4-5 The adjusting assembly 8 includes an adjusting block 81, which is slidably connected to the inner wall of the filter box 1. A rectangular adjusting groove is formed in the inner wall of the filter box 1. A push rod 83 is fixedly connected to the top of the adjusting block 81, passing through and slidably connected to the inner wall of the filter box 1. Pushing the push rod 83 causes the adjusting block 81 to slide within the adjusting groove. The side wall of the adjusting block 81 is elastically connected to the inner wall of the filter box 1 via a positioning spring 82. During the sliding process, the adjusting block 81 compresses the positioning spring 82, causing the positioning spring 82 to... When the deformation occurs and the device is reset, the rebound of the positioning spring 82 causes the adjusting block 81 to slide and reset. The top of the adjusting block 81 is fixedly connected to the adjusting frame 84, which is slidably connected to the inner wall of the filter box 1. The adjusting frame 84 is slidably driven by the sliding of the adjusting block 81. The adjusting frame 84 is L-shaped and is inserted into the adjusting groove. The adjusting groove is L-shaped and its size is larger than that of the adjusting frame 84. After the adjusting frame 84 slides, it pushes the connecting rod 9 upward to separate the adjusting frame 84 from the adjusting groove.

[0021] Working principle: When in use, pushing the push rod 83 causes the adjusting block 81 to press the positioning spring 82, which in turn causes the adjusting frame 84 to move. During the movement of the adjusting frame 84, it slides in the adjusting groove opened inside the connecting rod 9. After sliding to the appropriate position, pushing the connecting rod 9 presses the fixing plate 12, which in turn pushes the connecting spring 11, causing the connecting rod 9 to slide inside the connecting frame 2. The connecting rod 9 also causes the clamping plate 10 to slide. After sliding to the appropriate position, the filter box 1 is placed in the position to be used. Then, the clamping plate 10 is used to connect the filter box 1 to the connection point. After releasing the push on the connecting rod 9, the rebound of the connecting spring 11 causes the fixing plate 12 and the connecting rod 9 to slide back to their original positions. After the connecting rod 9 slides back to its original positions, the adjusting frame 84 is inserted into the adjusting groove. At the same time, releasing the push on the push rod 83 causes the positioning spring 82 to rebound, causing the adjusting block 81 and the adjusting frame 84 to rebound and insert into the adjusting groove, thus improving the stability of the connecting rod 9 and the clamping plate 10 during the clamping process. When the filter screen 3 becomes clogged after prolonged use and needs cleaning, the servo motor 4 drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the cleaning plate 6 to rotate, cleaning the side wall of the filter screen 3. The cleaned impurities fall to the bottom of the filter box 1. As the cleaning plate 6 rotates, it pushes the push block 72. The push block 72, after being pushed, causes the baffle plate 71 to press the return spring 73 and slide inside the filter box 1. After the baffle plate 71 slides, it leaks out of the discharge port at the bottom of the filter box 1, allowing the impurities to fall into the collection frame 13. As the cleaning plate 6 rotates, it releases the push block 72. The return spring 73 causes the baffle plate 71 to slide back to its original position, blocking the discharge port and preventing the overflow of impurities inside the collection frame 13. This improves the cleanliness of the filter box 1 during use and the accuracy of the test results.

[0022] 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.
