[0019] Specifically, the shell 2 is divided into two spaces by the partition plate 10, one of which is a working space 15 and the other is a maintenance space 14, and the two spaces can be replaced by the adjusting assembly 6, so that the working space 15 filters the exhaust gas and the filter screen 12 in the maintenance space 14 is cleaned by the cleaning assembly 7, thereby improving the practicability of the dry filter and the filtering efficiency of the exhaust gas.

[0020] The adjusting assembly 6 mainly comprises a driving motor 61, a rotating shaft 62, a circular valve 63 and a sealing bearing 64. The rotating shaft 62 penetrates the partition plate 10 from left to right and is rotatably connected with the partition plate 10. One end of one of the connecting pipes 3 is provided with the driving motor 61. The power output end of the driving motor 61 extends into the connecting pipe 3 and is connected with the rotating shaft 62. The other end of the rotating shaft 62 is rotatably connected with the other connecting pipe 3. The circular valve 63 is arranged on the outer side of the rotating shaft 62 and is rotatably connected with the shell 2 through the sealing bearing 64. The circular valve 63 is provided with a notch 65.

[0021] Specifically, the driving motor 61 is fixed on the connecting pipe 3. The power output end of the driving motor 61 is connected with the rotating shaft 62 through a shaft coupling. The rotating shaft 62 is driven to rotate 180 degrees by the driving motor 61, so that the circular valve 63 rotates and the notch 65 on the circular valve 63 is replaced between the working space 15 and the maintenance space 14, thereby improving the filtering efficiency of the dry filter.

[0022] Further, the cleaning assembly 7 mainly comprises a hydraulic cylinder 71, a connecting plate 72, a brush 73 and an upper top plate 74, the connecting plate 72 is arranged on one side of the filter screen 12, the brush 73 is arranged on the connecting plate 72, the upper surface of the connecting plate 72 is connected with the telescopic end of the hydraulic cylinder 71, the hydraulic cylinder 71 is fixed on the upper surface of the shell 2 through bolts, and the upper surface of the filter screen 12 is provided with the upper top plate 74, and the upper top plate 74 is provided with a hole through which the telescopic end of the hydraulic cylinder 71 passes.

[0023] Specifically, the telescopic end of the hydraulic cylinder 71 is slidably connected with the upper top plate 74, so that the connecting plate 72 and the brush 73 are driven by the hydraulic cylinder 71 to move up and down, thereby cleaning the filter screen 12, reducing the labor intensity of workers and the maintenance time of the filter screen 12, and improving the filtering efficiency of the filter screen 12 on the exhaust gas.

[0024] Further, the upper top plate 74 is provided with a first clamping groove corresponding to the filter screen 12.

[0025] Specifically, the filter screen 12 can be positioned through the first clamping groove.

[0026] Further, the connecting plate 72 is in the shape of “7”, and the brush 73 is arranged opposite to the filter screen 12.

[0027] Specifically, the brush 73 is arranged opposite to the filter screen 12, so that the brush 73 can clean the filter screen 12, reduce the labor intensity of workers, reduce the disassembly and replacement frequency of the filter screen 12, and thereby improve the filtering efficiency of the exhaust gas.

[0028] Further, the cleaning assembly 7 is provided below with a flow guide block 13, and the flow guide block 13 is provided at the bottom with a discharge port 9.

[0029] Specifically, the flow guide block 13 is provided with a second clamping groove corresponding to the filter screen 12, and the filter screen 12 can be positioned and fixed through the first clamping groove and the second clamping groove, thereby preventing the exhaust gas from leaking from the gap between the filter screen 12 and the shell 2, and improving the filtering quality of the filter screen 12.

[0030] More specifically, the impurities swept by the cleaning assembly 77 can be guided and discharged from the discharge port 9 through the setting of the flow guide block 13.

[0031] Further, the circular valve 63 is provided at the end away from the sealing bearing 64 with a baffle.

[0032] Specifically, the sealing bearing 64 is a face bearing, which assists the circular valve 63, thereby facilitating the rotation of the circular valve 63, and the baffle can prevent the exhaust gas from entering the partition plate 10 through the rotating shaft 62, thereby affecting the rotation of the rotating shaft 62.

[0033] In use: the exhaust gas enters the connecting pipe 3 through the inlet pipe 4, and enters the working space 15 through the gap 65 on the circular valve 63, is filtered by the two layers of filter screens 12, and is discharged from the outlet pipe 5.

[0034] When it is necessary to replace the working space 15 with the maintenance space 14, the rotating shaft 62 is rotated by 180 degrees by the driving motor 61, so that the circular valve 63 is rotated, and the gap 65 on the circular valve 63 is rotated from the working space 15 to the maintenance space 14, so that the maintenance space 14 becomes the working state, and the working space 15 becomes the maintenance state, and then the connecting plate 72 and the brush 73 are moved up and down by the hydraulic cylinder 71, so that the filter screens 12 are cleaned, and the impurities after cleaning are guided by the guide block 13 and discharged from the discharge port 9.

[0035] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
