[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: an impurity filtering device for chemical detection, comprising a filter box body 1, the top of the filter box body 1 is rotatably connected to a top cover plate 2, both sides of the filter box body 1 are fixedly connected to an air supply pipe 3, the bottom end of the inner part of the filter box body 1 is fixedly connected to a particle protection filter screen 11, and an outer wall cleaning component is installed on the outside of the particle protection filter screen 11, the inner sides of the filter box body 1 are rotatably connected to threaded rods 6, the outer bottom ends of the threaded rods 6 are fixedly connected to belt pulleys 7, and multiple belt pulleys 7 are connected by belts. The right side of the bottom end of the filter box body 1 is fixedly connected There is a support frame 5, the interior of the support frame 5 is fixedly connected with a driving motor 4, a filter element disassembly assembly is installed inside the particle protection filter 11, and the outer wall cleaning assembly includes a particle cleaning ring 14, and multiple support rods 12 are fixedly connected to both sides of the bottom end of the particle cleaning ring 14, and the bottom ends of the support rods 12 are fixedly connected with sealing arc blocks 8, and lifting blocks 9 are fixedly connected between adjacent support rods 12. The driving end of the driving motor 4 is fixedly connected to the bottom end of the right threaded rod 6, and the outer parts of the threaded rod 6 are respectively correspondingly threadedly connected to the inside of the lifting block 9, and the tops of the threaded rods 6 are fixedly connected with anti-slip sheets 10;

[0033] When too much particulate matter accumulates outside the particle protection filter 11, the drive motor 4 is started to rotate the threaded rod 6 on the right side. As the right threaded rod 6 rotates, the right belt pulley 7 is driven to rotate, so that the belt moves, and the belt drives the left belt pulley 7 to rotate. At this time, the threaded rods 6 on both sides rotate at the same time, and as the external thread of the threaded rod 6 contacts the internal thread of the lifting block 9, the lifting block 9 moves downward. As the lifting block 9 moves, the support rod 12 is driven, so that the particle cleaning ring 14 moves downward on the surface of the particle protection filter 11. The inner side of the particle cleaning ring 14 is close to the outer wall of the particle protection filter 11. The accumulated particles outside the particle protection filter 11 contact the downward moving particle cleaning ring 14 to scrape the particles off, and the sealing arc block 8 leaves the groove at the bottom end of the filter box body 1, and the debris is discharged to the outside along the groove to complete the cleaning, so as to avoid the ventilation effect of the filter being deteriorated due to the accumulation of particulate matter, ensure the filtration efficiency of the device, and facilitate the cleaning of the filter.

[0034] Reference Figure 2 and Figure 4 The filter element disassembly assembly includes a filter element collection frame 15, a fixing ring 16 is fixedly connected to the top of the filter element collection frame 15, and lifting rings 17 are rotatably connected to both sides of the top of the fixing ring 16. An activated carbon filter element 18 is nested inside the filter element collection frame 15, and a mounting disc 13 is threadedly connected to the top of the outer particulate protection filter screen 11. The inner side of the particle cleaning ring 14 is attached to the outside of the particle protection filter screen 11, and the outside of the sealing arc block 8 is nested in the bottom groove of the filter box body 1, and the outside of the filter element collection frame 15 is slidably connected to the inside of the particle protection filter screen 11;

[0035] The anti-slip sheet 10 limits the thread movement distance of the threaded rod 6 to prevent the threaded rod 6 from being detached. When the filtering effect of the filter element inside the device deteriorates, the top cover plate 2 is flipped upward and opened, and the mounting disc 13 is twisted so that the inner thread of the mounting disc 13 contacts the outer thread of the particle protection filter screen 11, so that the mounting disc 13 is detached from the particle protection filter screen 11. At this time, the activated carbon filter element 18 is exposed to the outside, and the lifting rings 17 on both sides of the top of the fixing ring 16 are used to rotate the lifting rings 17 inward at the same time to form a lifting handle, and the filter element collection frame 15 is pulled out from the inside of the particle protection filter screen 11, the activated carbon filter element 18 is taken out, and a new activated carbon filter element 18 is placed inside the filter element collection frame 15, and then installed to complete the replacement of the filter element, thereby avoiding the difficulty in replacing the filter element due to the deterioration of the filter element effect caused by long-term use, facilitating the replacement of the filter element by the device, and ensuring the filtering effect of the device.

[0036] Reference Figure 5 , a plurality of traction slopes 19 are provided on both sides of the inner bottom end of the filter box body 1;

[0037] The particles outside the particle protection filter 11 will fall to the connection of the groove at the bottom end of the filter box body 1 as the particle cleaning ring 14 hangs down, and the surface of the slapping device will cause vibration inside. The particles will flow downward through the inclined surface of the traction inclined surface 19 as the vibration occurs, and be discharged through the groove at the bottom end of the filter box body 1.

[0038] Working principle: The chemical waste gas is sent into the interior of the filter box body 1 through the air delivery pipe 3 on one side, and the waste gas enters the interior of the activated carbon filter element 18 through the particle protection filter 11. The particulate matter in the waste gas is blocked on the outside by the particle protection filter 11, and the waste gas contacts the activated carbon inside the activated carbon filter element 18 for purification and discharge. When too much particulate matter accumulates outside the particle protection filter 11, the drive motor 4 is started to rotate the threaded rod 6 on the right side. As the right threaded rod 6 rotates, the right belt pulley 7 is driven to rotate, thereby causing the belt to move. At the same time, the belt drives the left belt pulley 7 to rotate. At this time, the threaded rods 6 on both sides rotate at the same time, moving the lifting block 9 downward. As the lifting block 9 moves, it drives the support rod 12 to make the particles clean. The cleaning ring 14 moves downward on the surface of the particle protection filter 11, the particle cleaning ring 14 scrapes off the particles, and the sealing arc block 8 leaves the groove at the bottom end of the filter box body 1, and the debris is discharged outward along the groove to complete the cleaning. When the filtering effect of the filter element inside the device deteriorates, the top cover plate 2 is flipped upward and opened, and the mounting disc 13 is twisted to make the mounting disc 13 detach from the particle protection filter 11. At this time, the activated carbon filter element 18 is exposed to the outside, and the filter element collection frame 15 is pulled out from the inside of the particle protection filter 11 through the pulling rings 17 on both sides of the top of the fixing ring 16, the activated carbon filter element 18 is taken out, and a new activated carbon filter element 18 is placed in the filter element collection frame 15, and then installed to complete the replacement of the filter element.
