[0031] The first T-shaped rod 23 is fixedly connected to the upper and lower ends of the connecting frame 21 and is slidably connected to the first T-shaped groove 22, which is formed in the inner side of the connecting box 2. The first filter plate 27 is connected to the mounting frame 26 through the second knob 25. The second T-shaped rod 32 is fixedly connected to the two sides of the mounting frame 26 and is slidably connected to the second T-shaped groove 31, which is formed in the connecting frame 21.

[0037] When it is needed to clean the first filter plate 27 and the second filter plate 20, at this time, the telescopic cylinder 4 is started to drive the connecting frame 21 to move, the connecting frame 21 enters into the U-shaped plate 12 along the relief hole 17, and in the process that the connecting frame 21 moves, the upper end of the elastic pull rope 19 is connected with the first T-shaped groove 22, so that when the connecting frame 21 moves, the mounting frame 26 provided with the first filter plate 27 is driven to move upward, at this time, the folding cloth 24 is folded, the first filter plate 27 moves upward to be disengaged from the second filter plate 20, when the connecting frame 21 contacts with one end of the U-shaped plate 12, the telescopic cylinder 4 is closed at this time;

[0038] At the same time, the electromagnetic valve 35 is started, the gas in the gas tank 3 enters into the U-shaped plate 12 through the connecting pipe 5, the gas entering into the U-shaped plate 12 passes through the second filter plate 20 and the first filter plate 27 in turn, the filter surfaces of the first filter plate 27 and the second filter plate 20 are back-flushed, so that the impurities adhered and blocked on the filter surfaces are blown down, then the gas passes through the plurality of air holes 13 and is discharged to the external environment, when the cleaning is completed, the telescopic cylinder 4 is started to pull the mounting frame 26 provided with the first filter plate 27 into the connecting box 2 again, at this time, under the gravity of the mounting frame 26 and the first filter plate 27, the mounting frame 26 moves downward to return to the initial position, and at the same time, the folding cloth 24 is unfolded again;

[0039] When it is needed to replace the first filter plate 27 and the second filter plate 20, the connecting frame 21 is made to enter into the U-shaped plate 12 again, at this time, the L-shaped blocking plate 6 is pulled upward after the limiting knob 7 is loosened, when the L-shaped blocking plate 6 is pulled out, the first filter plate 27 and the second filter plate 20 can be replaced by loosening the second knob 25 and the first knob 33 in turn, after the replacement is completed, the connecting frame 21 is made to enter into the connecting box 2 again, and the L-shaped blocking plate 6 is inserted into the slot 18 again.
