A slide groove 9 is provided, and the slide groove 9 is connected to the inside of the processing box 1 through a support rod. At the same time, the slide groove 9 is used to guide the moving direction of the slider 13 and support the slider 13, thereby supporting the filter cartridge 8.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes: a delivery pipe 3, which is connected to the rotating pipe 15, and one side of the delivery pipe 3 passes through the processing box 1; a dust hood 2, which is arranged on one side of the processing box 1 and is connected to the delivery pipe 3. The dust hood 2 is arranged to guide the dust-containing gas into the dust removal device, ensuring that the dust-containing gas can be effectively collected and sent into the processing box 1.

[0029] like Figure 2 and Figure 3 As shown, it also includes: the bottom of the filter cartridge 8 is conical; the dust exhaust pipe 11 is connected and arranged at the bottom of the filter cartridge 8; and the feed pipe 10 is rotatably arranged on the surface of the dust exhaust pipe 11. By setting the bottom of the filter cartridge 8 to be conical, the conical bottom helps to concentrate the dust collected inside the filter cartridge 8 into a smaller area, which is convenient for the discharge of dust, and at the same time helps the dust to slide down along the inclined surface, reducing the retention of dust at the bottom of the filter cartridge 8; by setting the feed pipe 10, a control valve is arranged on the feed pipe 10 to control the opening and closing of the feed pipe 10, thereby controlling the falling of dust.

[0030] like Figure 2 As shown, it also includes: a collecting frame 7, which is arranged at the bottom of the inner cavity of the processing box 1; and a feeding pipe 10, which is connected and arranged in the collecting frame 7. By setting the collecting frame 7, a drawer is slidably arranged in the collecting frame 7, and the collected dust can be cleaned for unified processing.

[0031] like Figure 1 and Figure 2 As shown, it also includes: a water tank 6, which is arranged on one side of the treatment box 1; an exhaust pipe 5, which is connected to the treatment box 1 and connected to the water tank 6 on the other side; and the exhaust pipe 5 is U-shaped, and the lowest point of the exhaust pipe 5 is lower than the highest water level of the water tank 6 to form a water seal.

[0032] By setting up a water tank 6, a water inlet pipe and a drain pipe are provided on the water tank 6. The water inlet pipe and the drain pipe are both provided with control valves for controlling the opening or closing of the pipes. The water tank 6 is used to wash the filtered air with water to ensure that the discharged gas is cleaner; by setting up an exhaust pipe 5 with a U-shaped design, its lowest point is lower than the highest water level of the water tank 6, to ensure that dust-containing gas must be discharged through water, further purifying the gas, while preventing water from entering the interior of the treatment box 1 through the exhaust pipe 5.

[0033] like Figure 1 and Figure 2 As shown, it also includes: an injection unit 12, which is arranged on the processing box 1, and the injection unit 12 includes: a gas storage tank 122, which is arranged on the processing box 1. The gas storage tank 122 is provided to store compressed gas, so that the gas is sprayed to the surface of the filter cartridge 8 through the injection unit 12 to remove the dust attached to the surface. The gas storage tank 122 helps to stabilize the gas supply pressure and ensure that the pressure of the sprayed gas is sufficient to remove the dust.

[0034] like Figure 2 As shown, it also includes: an air supply pipe 123, which is connected to the air storage tank 122, and the air supply pipe 123 extends from the side of the air storage tank 122 to the inside of the air storage tank 122; a plurality of nozzles 121, which are arranged on the air supply pipe 123 and are located in the air storage tank 122 near the filter cartridge 8.

[0035] By setting the nozzle 121, continuous blowing can be designed to generate continuous negative pressure, so that the dust-containing air is continuously sucked into the dust hood 2 and then enters the treatment box 1. Periodic blowing can also be designed to generate necessary negative pressure and save energy consumption and reduce the load on the filter cartridge 8. The nozzle 121 can be in the shape of a narrow slit to generate high-speed airflow, which helps to more effectively remove dust on the filter cartridge 8. The nozzle 121 can be in a focusing shape to make the airflow more concentrated, increase the impact force on the surface of the filter cartridge 8, and enhance the cleaning effect.

[0036] The technical solution provided by the utility model is that the dust hood 2 is located above the production line, and the dust-containing gas first enters the dust hood 2, and then is sent into the filter cartridge 8 through the delivery pipe 3, which is beneficial for the external controller to start the motor 4 to move, and through the gear set 16, drives the rotating tube 15 to rotate, so that the filter cartridge 8 rotates. When the filter cartridge 8 rotates, it drives the slider 13 to move in the slide groove 9, and at the same time, it is beneficial for the external controller to start the movement of the air storage tank 122, and sprays gas to the surface of the filter cartridge 8 through the air delivery pipe 123 and the nozzle 121 to remove the dust attached to the surface of the filter cartridge 8. The cleaned gas is discharged into the water tank 6 through the exhaust pipe 5, and the air is adsorbed and cleaned again by the water in the water tank 6, and finally discharged from the top of the water tank 6; the dust in the filter cartridge 8 is discharged through the dust exhaust pipe 11, and the dust is sent to the collection frame 7.
