[0027] See also Figure 3 The driving assembly includes a motor 2 located on the inner wall of the pipeline 1. The motor 2 is a prior art and will not be described in detail here. An L-shaped rod 3 is provided at the output end of the motor 2. A hard thin plate 9 matched with the L-shaped rod 3 is provided inside the filter 10. The motor 2 drives the L-shaped rod 3 to rotate. During the rotation, the hard thin plate 9 is squeezed and collided. The tension spring 6 is stretched and the filter 10 shakes. After the L-shaped rod 3 is separated from the hard thin plate 9, the elastic force of the tension spring 6 drives the filter 10 to reset and collide with the inner wall of the slide 4. The filter 10 shakes again to achieve the shedding of solid powder particles on its surface.

[0028] See also Figure 3The inner wall of the pipe 1 is provided with two front and rear limit grooves 7, and the inner wall of the limit groove 7 is slidably connected with a limit block 8 fixedly connected to the filter screen 10. The limit groove 7 and the limit block 8 cooperate with each other to effectively improve the stability of the filter screen 10 when it moves on the inner wall of the pipe 1.

[0029] See also Figure 2 A guide groove 12 communicating with the feed hole 13 is provided on the inner wall of the pipe 1. The guide groove 12 is tilted downward near the side of the filter screen 10. The guide groove 12 can prevent the solid powder particles falling from the filter screen 10 from accumulating in the pipe 1. A mounting plate 20 is sleeved on the outer end of the pipe 1, and a plurality of mounting holes 21 are provided on the outer end of the mounting plate 20.

[0030] Example 2

[0031] The utility model provides an anti-clogging exhaust device, wherein the components identical or corresponding to those in embodiment 1 are marked with the corresponding reference numerals in embodiment 1. For the sake of simplicity, only the differences from embodiment 1 are described below. Figure 4 The cleaning component 14 includes a shell 15, and through holes are provided at both ends of the upper and lower ends of the shell 15. A carrying box 16 is rotatably connected inside the shell 15. A rubber sealing gasket adapted to the carrying box 16 is provided on the inner wall of the shell 15. The provision of the rubber sealing gasket can improve the airtightness between the shell 15 and the carrying box 16, so as to avoid that unfiltered exhaust gas is discharged from the gap between the two when processing solid powder particles. A driving rod 17 that runs through the shell 15 is fixedly connected to the outer end of the carrying box 16. The driving rod 17 is rotatably connected to the shell 15. A plurality of iron sheets 19 are provided on the side wall of the shell 15 near one end of the driving rod 17. A magnet 18 adapted to the iron sheet 19 is fixedly connected to the outer end of the driving rod 17. The solid powder particles entering from the feed hole 13 will fall into the carrying box 16. When the solid powder particles need to be cleaned, the user rotates the carrying box 16 180 degrees to make the solid powder particles fall from the through hole under the shell 15.

[0032] The working process of this utility model:

[0033] First, connect the left end of the device to the exhaust pipe, then connect the motor 2 to an external power source and turn on the switch. The filter 10 is continuously collided with the rotating L-shaped rod 3 to make the filter 10 shake, so that the solid powder particles can fall off, and the accumulation of solid powder particles can be effectively avoided to cause the mesh to be blocked. The detached solid powder particles will enter the cleaning component 14 through the feed hole 13. When the solid powder particles need to be processed, the carrier box 16 located inside the outer shell 15 is rotated 180 degrees to achieve rapid cleaning of the collected solid powder particles. Since the inner walls of the outer shell 15 and the carrier box 16 fit tightly, it can also effectively prevent the unfiltered exhaust gas from being discharged through the feed hole 13 and affecting the surrounding environment.

[0034] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
