[0032] An adsorption plate 14 is rotatably connected in the base 1, a rotating wheel 15 is fixedly connected to the top of the adsorption plate 14, and the rotating wheel 15 is rotatably connected to the top of the shell 2. An exhaust pipe 16 is provided on one side of the shell 2, a fan 18 is fixedly connected in the exhaust pipe 16, and third filter plates 17 are respectively provided at both ends of the exhaust pipe 16. A sliding track 20 is provided on the base 1, and a door panel 19 is slidably connected in the sliding track 20. The first clamping ring 4 and the second clamping ring 7 are of the same size and are symmetrically arranged at both ends of the gas pipeline 5. Four groups of limit bars 11 are provided, and two groups of limit bars 11 are symmetrically distributed on both sides of the second clamping ring 7. Two groups of limit bars 11 are symmetrically distributed on both sides of the first clamping ring 4, the limit bars 11 slide through the second clamping ring 7, the first filter plate 6 slides in the slide groove 9, the wedge blocks 13 are provided with two groups and are symmetrically distributed on both sides of the first filter plate 6, the limit bars 11 are in contact with the wedge blocks 13, the adsorption plates 14 are provided with two groups and are arranged perpendicular to each other, the adsorption plates 14 are provided with several groups of through holes, activated carbon is sandwiched in the adsorption plates 14, the output end of the fan 18 faces the outside of the outer shell 2, the first connecting pipe 3 and the exhaust pipe 16 are staggered on both sides of the adsorption plate 14, and the door panel 19 is provided with a handle and a door lock.

[0033] Working principle: when in use, the staff connects the second connecting pipe 8 to the paint spraying room, and then starts the fan 18, and forms a flowing airflow in the space inside the shell 2 through the exhaust pipe 16 and the gas pipeline 5, and forms a negative pressure in the shell 2 through the fan 18, and the exhaust gas in the paint spraying room first passes through the first filter plate 6 through the second connecting pipe 8 to preliminarily filter solid impurities, and then enters the gas pipeline 5, and then passes through the second filter plate 21 through the first clamping ring 4 and the first connecting pipe 3 to enter the shell 2, and the adsorption plate 14 is driven to rotate by the air flow, so that the exhaust gas can fully contact with the activated carbon through the through holes on the surface of the adsorption plate 14, thereby improving the adsorption efficiency, and then the exhaust gas is finally filtered through the third filter plate 17 and discharged to the outside of the shell 2. After the device has been running for a long time, the staff can move the pull bolts 12 on both sides of the second clamping ring 7 to move the limit stop bar 11 out from the surface of the wedge block 13, thereby threading the end of the gas pipeline with the first filter plate 6 connected to it. 5 slides out from the slide groove 9, and the first filter plate 6 is removed from the gas pipeline 5 by rotating, so as to facilitate the staff to replace it. The second filter plate 21 is replaced in the same way. After replacement, the first filter plate 6 is aligned with the second clamping ring 7 and inserted, and the limiting stopper bar 11 is squeezed by the inclined surface of the wedge block 13. The limiting stopper bar 11 drives the spring 10. When the right-angled surface of the wedge block 13 slides into the inner side of the limiting stopper bar 11, the limiting stopper bar 11 is clamped on the wedge block 13 by the spring 10 to restore the elastic deformation, thereby fixing the first filter plate 6 and completing the clamping fixation. The above operation is convenient for the staff to replace the first filter plate 6 and the second filter plate 21, and improves the exhaust gas filtering effect and use efficiency. The staff can understand the rotation of the adsorption plate 14 by observing the rotation of the rotating wheel 15. When the adsorption plate 14 fails or the activated carbon needs to be replaced, the staff opens the door lock on the door panel 19 and pulls the door handle to open the door panel 19, so as to facilitate the maintenance of the internal components of the shell 2.
