After the installation is completed, start the burner body (1) to spray fire. At the same time, the dust filter (7) can control the airflow entering the inside of the device. perform filtering; S3: When the dust filter (7) is blocked, the staff can start the motor (14), and the motor (14) will drive the switching plate (6) to rotate under the cooperation of the active rotating shaft (13) and the belt transmission structure, thus immediately The dust-proof net (7) that needs to be cleaned outside the air inlet chamber (4) can be rotated into the cleaning box (8), and the brush plate (10) can be rotated into the cleaning box (8) when the dust-proof net (7) rotates into the cleaning box (8). Make contact with it, so that the filtered dust brush on the dust filter (7) can be swept off; S4: The backflush fan (11) will rotate to the inside of the dust filter (7) during the rotation of the dust filter. Then the backflush fan (11) will blow back the dust filter (7), thereby making it easier to clean the dust filter. (7) For further cleaning, on the other hand, a set of dust screens (7) previously located in the cleaning box (8) will rotate to one side of the air inlet chamber (4) to continue dust filtration. 10. A dust-proof self-cleaning heat-resistant steel boiler burner and its use method according to claim 9, characterized in that: the use method of the adjustment mechanism (22) includes the following steps: S1: The fan (2203) continues to exhaust air into the air supply hood (2204) through the pipe. The wind in the air supply hood (2204) will be discharged to the air inlet silo (4) through the exhaust port above it, improving the air intake. The air inlet volume of the chamber (4) and the flame injection volume of the burner body (1); S2: When the lowest flame injection volume of the burner body (1) is still too large to meet the actual use needs, the staff can control the electric telescopic rod (2202) to push the adjustment top (2201) and stretch the return spring. (2207) drives the adjusting baffle (2206) to move upward, and uses the adjusting baffle (2206) to adjust the fire volume of the flame tube (2); S3: When the adjusting top (2201) moves upward, it will drive the air supply hood (2204) to move upward and away from the air inlet bin (4), reducing the air inlet volume inside the burner body (1).
