[0046] Secondly, the second hydraulic cylinder 23 can push the movable push block 14 and the rack plate 16 to move in the vertical direction inside the clamping frame 13. Since the rack plate 16 is meshed with the fixed gear 15, the rack plate 16 can push the fixed gear 15 to drive the fixed frame 18 to rotate through the connecting shaft 17, so that the color steel plate body 9 can be turned over and continue to be rinsed. Then, the waste liquid collection box 2 can be used to recover the waste liquid;

[0047] Then, the exhaust fan 39 can discharge the exhaust gas inside the purification device body 1 through the inside of the filter frame 31. The exhaust gas flows through the through hole 35 and several filter plates 36 inside the filter box 37 in turn. The filter plates 36 can provide multiple filtering treatments for the exhaust gas, and then the filtered gas is discharged.
