Specific implementation

[0025] The following will be further explained in detail in combination with the drawings. Figures 1-6 The application is further explained in detail.

[0026] The application discloses a paint baking waste gas purification device.

[0027] Refer to Figures 1-6A paint baking exhaust gas purification device includes a filter box 101 with an open top and a purification box 102. An air inlet pipe 103 connected to an air intake hood is installed on one side of the filter box 101. The air intake hood is positioned above the paint baking area. An air guide pipe 104 connected to the purification box 102 is installed on the other side of the filter box 101. An air outlet pipe 107 is provided at the top of the purification box 102. An activated carbon purification layer 105 is installed inside the purification box 102, and a desorption and regeneration mechanism 106 for activated carbon desorption and regeneration is provided on the bottom inner wall of the purification box 102. A cover plate 201 is installed on the top of 01. Multiple vertical rods 202 are fixedly installed on the bottom of the cover plate 201. The same upper filter frame 203 is fixedly installed on the bottom of the multiple vertical rods 202. Multiple connecting rods 204 are fixedly installed on the bottom of the upper filter frame 203. A lower filter frame 206 is fixedly installed on the bottom of the connecting rods 204. A sealing plate 205 is fixedly sleeved on the multiple connecting rods 204. Filter components 3 are provided in both the upper filter frame 203 and the lower filter frame 206. A sealing groove is opened on the outside of the sealing plate 205. A sealing strip is installed in the sealing groove.

[0028] In this embodiment, the filter assembly 3 includes a fine filter 302, a medium filter 303, and a coarse filter 304. The fine filter 302 is installed in both the upper filter frame 203 and the lower filter frame 206. The medium filter 303 is placed on top of the fine filter 302, and the coarse filter 304 is placed on top of the medium filter 303. This multi-layer filter combination can filter solid impurities in the exhaust gas in stages according to particle size, which greatly improves the accuracy and comprehensiveness of filtration, effectively reduces the impurity content entering the purification box 102, and extends the service life of subsequent purification equipment.

[0029] In this embodiment, multiple support seats 301 are installed on the inner walls of the upper filter frame 203 and the lower filter frame 206, and the fine filter screen 302 is placed on the corresponding support seat 301. The inner walls of the upper filter frame 203 and the lower filter frame 206 are provided with moving grooves 401. The moving grooves 401 are provided with fixing mechanisms for fixing the filter assembly 3. The fixing mechanism includes a protrusion 402 and a connecting spring 403. The protrusion 402 is slidably installed in the moving groove 401. A connecting spring 403 is fixedly installed on one side of the protrusion 402. One end of the connecting spring 403 is fixedly installed on the inner wall of the moving groove 401. The protrusion 402 is located above the coarse filter screen 304. The support seats 301 ensure the stability of the fine filter screen 302 installation. The fixing mechanism makes the installation and disassembly of the filter assembly 3 simple and efficient. The staff can quickly replace the filter assembly 3 without the need for complicated tools, which significantly improves the convenience of equipment maintenance.

[0030] In this embodiment, two fixing slots 501 are provided on one side of the vertical rod 202. The filter box 101 is provided with a mating mechanism on both sides that is adapted to the fixing slots 501. The mating mechanism includes a threaded hole 502, a fixing screw 503 and a knob 504. Threaded holes 502 are provided on the inner walls of both sides of the filter box 101. The fixing screw 503 is installed in the threaded hole 502. The fixing screw 503 is adapted to the corresponding fixing slot 501. A knob 504 is fixedly installed at one end of the fixing screw 503. With this mating mechanism, the operator only needs to turn the knob 504 to easily fix and disassemble the upper filter frame 203. The filter component 3 in the upper filter frame 203 can be replaced without stopping the machine, which greatly improves the flexibility of the equipment and reduces the production interruption time caused by equipment maintenance.

[0031] In this invention, the exhaust gas from the paint baking process is absorbed by the suction hood. The exhaust gas enters the filter box 101 through the air inlet pipe 103. The exhaust gas undergoes multiple filtrations through the coarse filter 304, medium filter 303, and fine filter 302 within the upper filter frame 203, effectively removing solid impurities. The filtered exhaust gas then enters the purification box 102 through the air guide pipe 104, where it is purified by the activated carbon purification layer 105. By rotating the knob 504 and the fixing screw 503, the screw 503 can rotate and move simultaneously through the threaded hole 502, allowing it to disengage from or insert into the fixing groove 501. This enables the vertical rod 2... 02 The purpose of fixing and unfixing is to move the cover plate 201 upward, which is carried by the vertical rod 202 to move the upper filter frame 203 upward, so that the upper filter frame 203 can be moved out of the filter box 101. At this time, the sealing plate 205 moves above the air inlet pipe 103, and the exhaust gas can be filtered through the lower filter frame 206. At this time, without stopping the machine, the filter component 3 in the upper filter frame 203 can be disassembled and replaced. By squeezing the protrusion 402, the protrusion 402 can compress the connecting spring 403 and be stored in the moving groove 401, which can release the fixation of the filter component 3, and the coarse filter screen 304, the medium filter screen 303 and the fine filter screen 302 can be disassembled, cleaned or replaced.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
