[0056] S3, then the staff need to start the motor 27 according to the actual situation through the top cover 8 in the support of the support plate 25 and the support 26, make the motor 27 drive the lead screw 28 to rotate with bearing as the center, make the lead screw 28 push the push plate 31 to move down under the guide cooperation of the guide groove 29 and the T plate 30, make the push plate 31 can move down through the perforated hole 32 under the action of the external force, make the hanging ring 33 can scrape off the dust adhered to the outside of the cloth bag 20 in the moving process, and the inner ring 34 will move down under the action of the external force through the supporting ring 35 to drive the brush 36 to adhere to the outside of the cloth bag 20, make the brush 36 can use its elasticity to sweep down the residual dust adhered to the outside of the cloth bag 20 under the action of the external force, so that the device can be self-cleaning;

[0057] S4, then the staff can hold the handle 54 according to the actual situation, and push the rotating column 50 to one side through the connecting rod 53, make the rotating column 50 drive the rubber ring 49 to move to the inside of the discharge pipe 7 under the action of the external force, and make the rotating column 50 drive the tapered head 51 to insert into the inside of the discharge pipe 7, at this time the tapered head 51 will insert into the dust blocked in the inside of the discharge pipe 7 by using its sharp end and external force, and push away the dust by using the inclination angle, then the staff need to rotate the connecting rod 53 through the handle 54, make the connecting rod 53 drive the tapered head 51 and the disturbance plate 52 to rotate through the rotating column 50 under the action of the external force, make the disturbance plate 52 can disturb the dust in the inside of the discharge pipe 7 under the action of the rotating power, and dredge the blockage.

[0058] S5, when the staff need to climb on the platform 23 to maintain the work, can first place the tools needed for maintenance to the inside of the storage barrel 58, then move the connecting belt 59 under the support of the storage barrel 58, make the connecting ring 60 move to the waist position of the staff, then the staff need to put the connecting ring 60 on the outside of the own trouser belt, make the storage barrel 58 can be connected with the waist of the staff through the connecting belt 59, the connecting ring 60 and the trouser belt of the staff, then the staff can climb up to the top of the platform 23 through the ladder 22, at the same time the waist trouser belt of the staff will move the storage barrel 58 up through the connecting ring 60 and the connecting belt 59 under the action of the external force in the climbing process, make the storage barrel 58 drive the tools needed for maintenance placed in the inside to move up under the support of the positioning plate 55 and the guide cooperation of the sleeve 57 and the guide rod 56, when moving to the position of the platform 23, the staff can take out the tools from the inside of the storage barrel 58 and separate the connecting ring 60 from the own trouser belt.

[0059] Further, in step S3, the following steps are further included:

[0060] S31. When the device is self-cleaning, the operator needs to stop the dusty gas from entering the inside of the air inlet pipe 10, and at the same time start the ash discharge pump 6 under the support of the ash hopper 5 to perform ash discharge work, so that the dust inside the ash hopper 5 can be discharged to the inside of the discharge pipe 7, and then discharged through the discharge pipe 7 to the connected ash discharge pipeline for transportation.

[0061] S32. When dust falls into the inner side of the ash hopper 5, some of the dust will fall to the top of the inclined plate 37 under the action of gravity. Supported by the main body 4, the inclined plate 37, with its own tilt angle, allows the dust to slide down its slope to one side of the interceptor plate 38, and then slide along the interceptor plate 38 around the air inlet pipe 10 to the inner side of the ash hopper 5. This prevents dust from falling into the opening of the air inlet pipe 10 and being difficult to expel. Simultaneously, when gas enters the inner side of the ash hopper 5 through the air inlet pipe 10, the gas will pass through the baffle 42 under the action of impact and the support of the interceptor plate 38. Pushing the valve stem 40 to one side causes the valve stem 40 to push the air valve 41 away from the interceptor plate 38 under the action of external force. At the same time, the spring 44 is compressed and contracted under the support of the interceptor plate 38, which opens the movable hole 39, allowing gas to pass through the air hole 43 and the movable hole 39 into the inner side of the ash hopper 5. When the gas supply stops, the spring 44 will use its rebound force to push the valve stem 40 and the air valve 41 through the baffle 42, so that the air valve 41 engages with the movable hole 39, closing the movable hole 39, allowing the dust to slide down the interceptor plate 38 around the air inlet pipe 10 to the bottom.

[0062] Working principle: Before using the device, the operator should check whether there are any problems that may affect its use. When the operator needs to use the device, the device should be securely installed at the work site from the fixed plate 1 using the fixing parts. Then, the pipe for conveying dusty gas is connected to the inlet pipe 10 using the fixing parts, and the pipe for conveying filtered gas is connected to the exhaust pipe 12. At the same time, the discharge pipe 7 is connected to the ash discharge pipe using the fixing parts. The device is then powered on. The start interval of the pulse valve 15 is set according to the actual needs. Finally, the dusty gas enters the inside of the inlet pipe 10 and the fan 11 is started to exhaust the gas. At the same time, the ash discharge pump 6 is started to discharge the ash.
