The position of one end of the filter screen 3, which is close to the threaded rod 20, is connected with the contact block 34 corresponding to the threaded rod 20, and the threaded rod 20 is impacted on the contact block 34, so that the impact force on the filter screen 3 is reduced, and the service life of the filter screen 3 is prolonged.
The driving shaft 8 and the driven shaft 9 are both rotatably connected to the top of the treatment box 5 through bearings, so that abrasion between the driving shaft 8 and the driven shaft 9 and the treatment box 5 is avoided.
In the invention, when the gas for removing ash and dust enters the treatment box 5 and is mixed with the water mist sprayed by the water mist spray head 6 and the ammonia gas released by the ammonia gas supply pipe 7, a first driving motor 13 on a support frame 12 is started, the first driving motor 13 drives a driving gear 14 and a driving shaft 8 to rotate clockwise, a driven gear 11 meshed with the driving gear 14 drives a driven shaft 9 to rotate anticlockwise, and the driving shaft 8 and the driven shaft 9 respectively drive corresponding stirring blades 10 to move in opposite directions, so that the uniform mixing speed of the gas for removing ash and dust in the treatment box 5, the water mist and the nitrogen gas is accelerated, and the working efficiency of a system is improved; the current direction of the second driving motor 18 is controlled to further change the rotation direction of the second driving motor 18, the second driving motor 18 drives the second bevel gear 25 to rotate, the first bevel gear 24 meshed with the second bevel gear 25 drives the threaded sleeve 19 to rotate, the threaded rod 20 can only do linear motion under the limiting action of the sliding rod 21, the T-shaped sliding groove 22 and the T-shaped sliding block 23, therefore, the threaded rod 20 can move forwards or backwards according to the steering direction of the threaded sleeve 19, when excessive dust is accumulated on the filter screen 3, the steering direction of the second driving motor 18 is reciprocally controlled to enable the threaded rod 20 to reciprocally strike on the filter screen 3, dust accumulated on the filter screen 3 is knocked down, the dust is prevented from blocking the screen diameter of the filter screen 3, and the working efficiency of the system is further improved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
