A processing pipe is housed between the baffles, and a filter mechanism is installed inside the processing pipe. When the circulating pump on the return pipe circulates the gas in the processing tank, the gas is first filtered by a filter screen. Then, the airflow impact causes the impeller to rotate, which in turn causes the steel brush coaxial with the impeller to rotate and clear the filter screen, preventing blockage and ensuring stable gas filtration and recovery.

[0015] 2. This utility model features sliding sleeves on both the outlet pipe and the return pipe. These sleeves are elastically supported by guide sleeves, guide rods, and springs. Additionally, a positioning pin is provided on the sleeve, which can be engaged with the treatment pipe.
