It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a dry dust removal filter element, such as... Figures 1-5 As shown, it includes:

[0028] Cylinder 1, with an air inlet 2 at the top;

[0029] Multiple arc-shaped plates 10 are arranged circumferentially along the axis of the cylinder 1. The side wall of the cylinder 1 is provided with a mounting slot for mounting the arc-shaped plates 10. One end of the arc-shaped plate 10 is rotatably connected to the cylinder 1.

[0030] The arc-shaped filter layer 5 is installed inside the arc-shaped plate 10. The arc-shaped filter layer 5 is inserted into the arc-shaped plate 10 from the top. The inner and outer walls of the arc-shaped plate 10 are provided with through holes for air to pass through the arc-shaped filter layer 5.

[0031] A drive mechanism for synchronously rotating multiple curved plates 10;

[0032] During operation, dusty air enters the cylinder 1 through the air inlet 2, is filtered by the arc-shaped filter layer 5, and is then discharged. After the set time has elapsed, the drive mechanism can drive multiple arc-shaped plates 10 to rotate out of the cylinder 1 at the same time, leaving the cylinder 1 in an open state. This facilitates cleaning of the dust inside the cylinder 1 and on the arc-shaped filter layer 5, and also makes it easy to disassemble and replace the arc-shaped filter layer 5.

[0033] The drive mechanism includes:

[0034] The rotating ring 7, which is rotatably mounted on the bottom of the cylinder 1 along a coaxial line, can be rotatably mounted via a bearing. The rotating ring 7 can be fixedly connected to the bottom of the cylinder 1 via fastening bolts 9.

[0035] A connecting rod 6 is hinged to the middle of the lower surface of each arc plate 10, and the end of the connecting rod 6 away from the arc plate 10 is hinged to the rotating ring 7.

[0036] When cleaning or replacement is required, loosen the fastening bolt 9, rotate the rotating ring 7, and the rotating ring 7 drives the arc plate 10 to rotate through the connecting rod 6. The arc plate 10 rotates out of the range of the cylinder 1. After cleaning or replacement, rotate the rotating ring 7 to reset the arc plate 10, and tighten the fastening bolt 9 to fix the rotating ring 7.

[0037] Preferably, a sealing layer 13 is provided between the arc-shaped plate 10 and the side wall of the cylinder 1 to improve the sealing performance.

[0038] In this embodiment, the bottom of the cylinder 1 is funnel-shaped and has an outlet. A dust collection bottle 8 is detachably connected to the outlet and can be connected by threads to collect falling dust.

[0039] In a specific implementation, the cylinder 1 is provided with a hollow tube 3 with an open top. The hollow tube 3 is rotatably connected to the top of the cylinder 1 and communicates with the air inlet 2. It can be rotatably connected by a bearing. Preferably, the air inlet 2 and the hollow tube 3 are arranged coaxially with the cylinder 1. Multiple air outlets 4 are opened along the length direction of the hollow tube 3. Dust-laden air enters the hollow tube 3 from the air inlet 2 and is then sprayed out from the air outlets 4, dispersing the air throughout the cylinder and making full use of the filtration area of ​​the arc-shaped filter layer 5.

[0040] Furthermore, a mounting shaft 12 is coaxially arranged inside the hollow tube 3. The mounting shaft 12 is fixed to the bottom end of the hollow tube 3 in an integrated manner. At least one set of fan blades 11 is fixed on the mounting shaft 12. When air enters the hollow tube 3, it blows the fan blades 11, causing the fan blades 11 to drive the hollow tube 3 to rotate through the mounting shaft 12, thereby causing the hollow tube 3 to rotate and exhaust air, making the air more dispersed.

[0041] In summary, this utility model provides a dry dust removal filter element, the working principle of which is as follows:

[0042] Dust-laden air enters the hollow tube 3 through the air inlet 2, blowing the fan blades 11. The fan blades 11 drive the hollow tube 3 to rotate via the mounting shaft 12, and then spray out from the air outlet 4, dispersing the air throughout the entire cylinder. After being filtered by the arc-shaped filter layer 5, the air is discharged. When cleaning or replacement is required, loosen the fastening bolts 9 and rotate the rotating ring 7. The rotating ring 7 drives the arc-shaped plate 10 to rotate via the connecting rod 6. The arc-shaped plate 10 rotates out of the range of the cylinder 1. After cleaning or replacement, rotate the rotating ring 7 to reset the arc-shaped plate 10, and tighten the fastening bolts 9 to fix the rotating ring 7.
