[0022] Please refer to Figures 1 - 4 As shown in the figure, the automatic dust cleaning and backwashing mechanism of the dust removal filter element includes a housing 1. Support feet 2 are fixedly connected to the surface of the housing 1. A top cover 4 is fixedly installed at the top of the housing 1. An installation hole 41 is opened near the center of the surface of the top cover 4. A filter element main body 6 is snap-fitted inside the installation hole 41. An installation shell 7 is fixedly connected to the top of the filter element main body 6. An intake valve 5 is fixedly connected to the side of the housing 1. An exhaust valve 8 is fixedly connected to the side of the installation shell 7. A backflush valve 9 is fixedly connected to the top of the installation shell 7. A sewage discharge valve 10 is fixedly connected to the bottom of the housing 1;

[0023] Furthermore, an installation frame 13 is fixedly connected to the bottom of the installation shell 7. A base 14 is rotatably connected to the inside of the installation frame 13. The shape of the base 14 is frustum-shaped;

[0024] During operation, due to the frustum-shaped structural design of the base 14, it is convenient for the air flow entering through the backflush valve 9 to be evenly dispersed on the inner wall of the filter element main body 6.

[0025] Furthermore, a plurality of inclined plates 15 are connected around the surface of the base 14 at equal angles. The base 14 is arranged directly below the backflush valve 9;

[0026] During operation, due to the structural design that a plurality of inclined plates 15 are connected around the surface of the base 14 at equal angles, it is convenient for the inclined plates 15 to rotate and blow the inner wall of the filter element main body 6 with the air flow, improving the cleaning effect of the device.

[0027] Furthermore, a support plate 11 is fixedly connected to the inner wall of the housing 1. The size of the support plate 11 matches the size of the filter element main body 6;

[0028] During operation, due to the structural design that the size of the support plate 11 matches the size of the filter element main body 6, the support plate 11 plays a role in supporting and limiting the filter element main body 6.

[0029] Furthermore, a rotating plate 12 is rotatably connected to the surface of the top cover 4. The surface of the rotating plate 12 abuts against the top of the filter element main body 6;

[0030] During operation, due to the structural design that the rotating plate 12 is rotatably connected to the surface of the top cover 4 and the surface of the rotating plate 12 abuts against the top of the filter element main body 6, the stability of the installation of the filter element main body 6 is improved.

[0031] Furthermore, the bottom of the outer shell 1 is conical, and a bolt 3 is fixedly connected to the top of the outer shell 1. The outer shell 1 is fixedly connected to the top cover 4 through the bolt 3;

[0032] During operation, due to the conical structure design of the bottom of the outer shell 1, it is convenient to discharge the dust inside the outer shell 1, reducing the possibility of dust accumulation. The top of the outer shell 1 is fixedly connected to the top cover 4 through the bolt 3, improving the stability of the device during operation.

[0033] Working principle: First, the filter element body 6 is snap-fitted into the installation hole 41 and abuts against the surface of the support plate 11. The rotating plate 12 is rotated to an appropriate angle to fix the filter element body 6. The top cover 4 and the outer shell 1 are fixed through the bolt 3, facilitating the disassembly and assembly of the top cover 4 to clean the inside of the outer shell 1. Polluted gas is filled into the device through the intake valve 5. The exhaust valve 8 is opened, and the gas is discharged through the exhaust valve 8 after being filtered by the filter element body 6. After the device has been working for a long time, a large amount of dust may adhere to the surface of the filter element body 6. At this time, the intake valve 5 and the exhaust valve 8 are closed, and the backflush valve 9 and the drain valve 10 are opened. At this time, clean air is filled through the backflush valve 9. The air rushes towards the base 14 rotatably connected to the mounting frame 13 directly below the backflush valve 9. Through the frustum-shaped base 14 and the equally-angled inclined plates 15, the air is evenly blown towards the filter element body 6, and the dust is discharged through the conical bottom of the outer shell 1, reducing the possibility of dust accumulation and improving the cleanliness of the device.
