The right end of the rotating rod 11 is rotatably connected to the scraper 12. During the movement of the linkage rod 10, the rotating rod 11 can move, thereby making the scraper 12 have a reciprocating effect.

The left side of the water outlet 13 is fixedly connected to the right bottom of the treatment box 2. The water outlet 13 can transmit the water source inside the treatment box 2. The top of the water outlet 13 is fixedly connected to a valve 14, which can control the discharge of the water outlet 13.

[0034] Reference Figures 2 to 4, a gas pipe 15 is fixedly connected to the top of the rear end of the processing box 2, and two stabilizing plates 17 are fixedly connected to the upper and lower ends of the gas pipe 15. The adjacent ends of the two stabilizing plates 17 are rotatably connected to a positioning rod 18, and the positioning rod 18 can be adjusted at a large angle through the two stabilizing plates 17. The rear sides of the adjacent ends of the two positioning rods 18 are fixedly connected with a bayonet 19, and the bayonet 19 can be fixed in the subsequent workpiece. The rear end of the gas pipe 15 is fixedly connected to a connecting pipe 16, and the gas pipe 15 and the connecting pipe 16 can be connected to each other through the subsequent workpiece. The adjacent ends of the two bayonet pins 19 are engaged with the upper and lower sides of the connecting pipe 16, and the gas pipe 15 and the connecting pipe 16 can be fixed on one side through the bayonet pin 19;

[0035] The inside of the gas pipe 15 is fixedly connected with a sealing gasket 27, and the outer rear end of the sealing gasket 27 is fixedly connected to the inner front end of the connecting pipe 16. The sealing gasket 27 can seal the connection between the gas pipe 15 and the connecting pipe 16 to prevent gas leakage and other adverse consequences. The outside of the gas pipe 15 is slidably connected with a clamp 20, which is convenient for installation through the sliding relationship. At the same time, the clamp 20 is a rotating relationship. The outside of the connecting pipe 16 is slidably connected to the inside of one of the clamps 20, and the other clamp 20 also slides on the outside of the connecting pipe 16. The internal threads of the two clamps 20 are connected with multiple bolts 21, and the two clamps 20 can be installed together through the bolts 21. The outer sliding connection of the bolt 21 is a gasket 22, and the outer rear end of the bolt 21 is threadedly connected with a nut 23. The front end of the gasket 22 contacts the rear end of one of the clamps 20, and the rear end of the gasket 22 contacts the front end of the nut 23. At the same time, the function of the gasket 22 is to prevent shaking between the bolt 21 and the nut 23.

[0036] The left sides of the two clamps 20 are fixedly connected with a fixing component for installing the clamps 20, and the fixing component includes two docking plates 24, and the front and rear sides of the far ends of the two docking plates 24 are respectively fixedly connected to the left sides of the two clamps 20, and a card hole 28 is opened inside one of the docking plates 24, and the internal thread of one of the docking plates 24 is connected to a rotating bolt 25, and the outside of the rotating bolt 25 is fixedly connected to a blocking block 26, and the bottom of the blocking block 26 contacts the top of one of the docking plates 24 through the blocking hole 28 opened in one of the docking plates 24. The rotating rotating bolt 25 can be raised and lowered. When the rotating bolt 25 is raised and lowered, it can drive the blocking block 26 to press the top of one of the docking plates 24, and at the same time, the position between the blocking block 26 and the card hole 28 can be staggered, thereby achieving mutual fastening of the two clamps 20.

[0037] Working principle: When it is necessary to transmit gas to the inside of the processing box 2, first, the connecting pipe 16 and the gas pipe 15 are connected to each other, and then the two clamps 20 are connected to each other through the bolt 21. Then, a gasket 22 and a nut 23 are connected to the outside of the bolt 21, so that the two clamps 20 can be installed and fixed to each other, and the docking plates 24 on the other side of the two clamps 20 can be engaged with each other. Through the card hole 28 opened in one of the docking plates 24, the rotating bolt 25 can be raised and lowered. When the rotating bolt 25 is raised and lowered, it can drive the card block 26 to press the top of one of the docking plates 24, and at the same time, the card block 26 and the card hole 2 8 are staggered, thereby achieving mutual fastening of the two clamps 20. The relationship between the two clamps 20 is a rotational relationship. When the positioning block 26 tightly fitted on the docking plate 24 is loosened, the positioning block 26 can pass through the inside of the card hole 28 to thereby disassemble the two clamps 20. At the same time, the positioning rod 18 rotating by the stabilizing plate 17 can be adjusted in a wide range of angles. By inserting the positioning rod 18 into the inside of the connecting pipe 16, a secondary fastening effect can be achieved. At the same time, the outside of the sealing gasket 27 is installed at the place where the gas pipe 15 and the connecting pipe 16 are connected to each other. This not only allows the gas pipe 15 and the connecting pipe 16 to be quickly installed and fixed, but also ensures the sealing effect.

[0038] When it is necessary to clean the particles transmitted in the exhaust gas, first start the motor 8 to drive the rotary rod 9 to rotate forward and reverse. When the rotary rod 9 rotates, it can drive the linkage rod 10 to move in one direction, and the linkage rod 10 can drive the rotating rod 11 to move when moving. At the same time, during the movement of the rotating rod 11, the scraper 12 can scrape the activated carbon filter plate 6 back and forth, so that the material on the top of the activated carbon filter plate 6 is pushed to the inside of the collection box 4 for collection. The water source transmitted by the water pipe 5 and the transmitted exhaust gas are combined with each other to form hot water, which can be recycled and reused. When the treated water source is discharged from the inside of the water outlet 13.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
