The pneumatic cleaning device 3 as shown in fig. 4-6 comprises slide rails 301 arranged at two sides in the frame 1, and the slide rails 301 are matched with slide blocks 312. A screw rod (not shown) is arranged in the slide rail 301, the sliding blocks 302 are matched and connected with the screw rod, and the two sliding blocks 302 are connected with a fixing box 303 together. The middle part of the fixed box 303 is slidably sleeved with a control shaft 304, and the top of the control shaft 304 is fixedly connected with a high-pressure air inlet pipe 305. The bottom of the control shaft 304 is fixedly connected with a high-pressure air pipe 306. The high-pressure gas pipe 306 is connected to the high-pressure gas inlet pipe 305. The high-pressure gas pipe 306 is connected with a gas storage box 307. The air storage box 307 is fixedly connected with a pneumatic valve 308, and the pneumatic valve 308 is connected with an air injection pipe 309. A fixing plate 310 is fixedly connected to one side of the gas lance 309. The control shaft 304 is fixedly connected to the fixing plate 310. The other side of the fixing plate 310 is provided with a guide rail 311. The guide rail 311 is connected with a slide block 312 in a matching manner, the slide block 312 is fixedly connected with a pneumatic stepping motor 313, the bottom of one side of the pneumatic stepping motor 313 is fixedly connected with a gear, the gear is matched with a gear rod 315, and the gear rod 315 is fixedly connected with the fixing plate 310. The fixed box 303 is provided with air cylinders 316 at two sides of the control shaft 304, and the bottoms of the air cylinders 316 are fixedly connected with the fixed box 303. A piston 317 is disposed on the top of the cylinder 316, and a moving plate 318 abuts against the piston 317. The moving plate 318 is connected to the control shaft 304 by a bearing, and the fixed box 303 is provided with a pneumatic stepping motor 319 on one side of the control shaft 304. The pneumatic stepping motor 319 is connected with a first belt pulley 320, the first belt pulley 320 is matched with a belt 321, the other side of the belt 321 is matched with a second belt pulley 322, and the second belt pulley 322 is fixedly connected with the control shaft 304.

When the pneumatic cleaning device starts to operate, the position of the gas jet 309 is adjusted to the outer edge position of the DPF8 by a high-pressure stepping motor, and then gas is introduced. The gas enters the control shaft 304 through a high-pressure intake pipe 305. The gas in the control shaft 304 flows along the high pressure gas pipe 306 into the gas storage box 307. Pressure is maintained stable by the gas cartridge 307, and high pressure gas in the gas cartridge 307 enters the gas injection tube 309 through the pneumatic valve 308, so that the gas is ejected to impact the upper surface of the DPF8, and particulate matter on the inner surface of the DPF8 is separated from the DPF 8. At the same time, the pneumatic stepper motor 319 rotates the first pulley 320. The first pulley 320 moves the belt 321, thereby rotating the second pulley 322. The second pulley 322 rotates to rotate the control shaft 304. As the control shaft 304 rotates, now off-center with the gas lance 309 in position at the outer edge of the DPF8, the gas lance 309 rotates around center one turn around the outer edge of the DPF8, cleaning the outer edge of the DPF 8. After rotating for a circle, the pneumatic stepping motor 319 rotates reversely to prevent the high-pressure air pipe 306 from knotting.

Next, the pneumatic stepping motor 313 operates to rotate the gear. The gear rotation causes the gear rod 315 to move, thereby causing the fixed plate 310 to move a distance that is less than the diameter of the gas lance 309. The fixed plate 310 moves to move the gas lances 309 the same distance toward the center of the DPF 8. Repeating the above steps, the pneumatic stepping motor 319 drives the gas injection pipe 309 to rotate around the center of the DPF8, and the inside of the outer edge of the DPF8 is cleaned at a certain distance. After repeating the above steps several times, the surface of the DPF8 is completely cleaned, and the gas nozzle 309 is located at the center of the DPF 8. The whole process is controlled by the PLC control device 2.

When the air injection of each air injection pipe 309 is completed, the air cylinder 316 drives the moving plate 318 to move upwards by one displacement, so that the air injection pipe 309 is not contacted with the surface of the DPF8 any more, and when the air injection pipe 309 rotates by a small angle to clean another position, the air cylinder 316 moves downwards by one displacement, so that the air injection pipe 309 is abutted against the DPF8 to be cleaned. With this arrangement, the gas lance 309 is prevented from moving when it is in direct contact with the surface of the DPF8, the gas lance 309 is prevented from being worn, and the service life of the gas lance 309 is extended.

As shown in fig. 7 to 10, the collecting device 5 includes a cylindrical filter element 501 provided with a plurality of fine holes (not shown) through which air passes but PM particles cannot pass.
