DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes an anti-icing and high-efficiency clean gas filter, comprising:

[0023] The housing 1 has a detachable upper cover 4 and a lower cover 16 installed at the upper and lower ends of the housing 1, respectively. The upper cover 4 and the lower cover 16 are connected to the housing 1 by bolts, which can ensure the stability of the connection therebetween and facilitate the disassembly of the upper cover 4 and the lower cover 16 so as to disassemble and replace the conical net 12; an air inlet pipe 2 and an air outlet pipe 3 are installed on the housing 1, the air inlet pipe 2 is located below the conical net 12, and the air outlet pipe 3 is located above the conical net 12, so that the conical net 12 can be used to filter the gas, and the air inlet pipe 2 and the air outlet pipe 3 are installed with connecting flanges so as to be connected to external pipelines;

[0024] A self-cleaning gas filter assembly; the gas filter assembly comprises a motor 5 mounted on an upper cover 4, the output end of the motor 5 is fixedly connected to a sleeve 6, a connecting rod 7 which can rotate synchronously and is movably arranged is arranged in the sleeve 6, the inner wall of the sleeve 6 is a rectangular groove 14, a rectangular block 15 is slidably connected in the rectangular groove 14, the rectangular block 15 is fixedly connected to the connecting rod 7, when the sleeve 6 is driven by the motor 5, the rectangular block 15 and the connecting rod 7 are driven to rotate, and the rectangular block 15 can also slide in the rectangular groove 14, wherein a through hole is arranged on the sleeve 6 so that air can enter or be discharged from the sleeve 6;
