The movement of the first docking column 204 and the second docking column 207 drives the first support plate 13 and the second support plate 17 to move. The movement of the support plate 13 and the second support plate 17 drives the first filter screen 14 and the second filter screen 15 to move in the opposite direction. When the docking block 203 moves to be separated from the first docking column 204 and the second docking column 207, the first docking column 204 and the second docking column 207 are moved out of the interior of the fixing seat 201, and the box door 5 is opened to take out the first filter screen 14 and the second filter screen 15 from the inner cavity of the box body 1, and then the first filter screen 14 and the second filter screen 15 can be replaced. When the first filter screen 14 and the second filter screen 15 are installed, , push the disc 206, the movement of the disc 206 drives the docking block 203 to move, insert the first docking column 204 and the second docking column 207 into the first slide groove 210 respectively, and release the docking rod 202. At this time, due to the reset function of the first spring 205 and the second spring 208, the docking rod 202 and the docking block 203 are returned to their original positions, and then the first docking column 204 and the second docking column 207 can be clamped with the docking block 203, so as to achieve the purpose of fixing the first filter screen 14 and the second filter screen 15. The refrigerant waste liquid is transmitted to the interior of the box body 1 through the feed pipe 4, and is drained to the surfaces of the first filter screen 14 and the second filter screen 15 through the first drainage box 10, and is drained to the bottom of the inner cavity of the box body 1 through the second drainage box 11. The reaction liquid is transmitted from the dosing pipe 307 to the interior of the box body 1, and the rotating rod 302 is driven to rotate by the operation of the motor 301. The rotation of the rotating rod 302 drives the stirring rod 303 to rotate, so that the refrigerant waste liquid and the reaction liquid can be fully mixed, thereby improving the treatment effect of the refrigerant waste liquid.
