[0024] Please refer to Figure 2 With Figure 3 The lower end of air inlet 2 is fixedly connected with suction air duct 19 located below the spark catcher, and the end, away from air inlet 2, of suction air duct 19 is communicated with the inside of filter cartridge chamber 5.

[0025] The left and right sides of no.

[0026] Please refer to Figure 3 With Figure 4The fan assembly 10 comprises a motor 101 and an impeller 102, the lower end of the output shaft of the motor 101 is fixedly connected with the impeller 102, the motor 101 provides power for the rotation of the impeller 102, and the outer wall of the motor 101 is fixedly sleeved with the inner wall of the sound-absorbing plate 11.

[0027] The lower end surface of the ash bucket 16 is provided with universal wheels 17, and the rolling of the universal wheels 17 can realize the movement of the ash bucket 16. The ash bucket 16 is fixedly installed with a push rod 21 on one side.

[0028] Working principle: in use, first, six air supply openings 6 are formed on the left and right sides and the front of the shell 1, and the air supply louvers 7 are installed inside the air supply openings 6. The blade direction of the air supply louvers 7 is manually adjusted, and the air supply louvers 7 can realize air supply within an angle range of 270°. The smoke and dust gas generated by welding enters the inside of the shell 1 from the air inlet 2. The gas entering the inside of the air inlet 2 contacts the spark catcher first. The spark catcher is a stainless steel filament laminated woven structure, which can intercept large particles of dust in the dust-containing gas and also plays a role in isolating sparks. After the dust-containing gas passes through the spark catcher, it enters the inside of the air suction duct 19, and then passes through the fire-resistant filter 9. After the dust-containing and spark-containing gas enters the labyrinth structure of the fire-resistant filter, the large particles and sparks will collide with the labyrinth structure and be intercepted outside during the second bending. After further removing sparks, the gas enters the inside of the filter cartridge chamber 5. The gas in the filter cartridge chamber 5 is filtered by the filter cartridge 8. The filter cartridge 8 is made of nanometer fire-resistant filter paper folded and added with a cartridge bottom cover and a mounting chuck structure. The smoke and dust are intercepted outside by the filter cartridge 8. The filtered clean low-speed airflow is drawn away from the middle flow channel of the filter cartridge 8 by the fan assembly 10. The high-speed rotation of the impeller 102 throws out the airflow. The clean air passes through the sound-absorbing plate 11 and then enters the second air exhaust channel 20 through the first air exhaust channel 12. After passing through the second air exhaust channel 20, the air is sent into the workshop through the air supply louvers 7 on the side and the front for recirculation. Then, the filtered dust particles are adsorbed on the surface of the filter cartridge 8. The 0.45-0.6 MPa compressed air in the backflush valve 14 is blown out instantaneously to blow off the dust particles attached to the surface of the filter cartridge 8 under the automatic backflush cleaning function of the opening of the backflush valve 14. The dust particles fall into the ash bucket 16 at the bottom of the equipment. Finally, the worker pushes the ash bucket 16 through the push rod 21 and moves the air supply opening 6 by rolling the universal wheels 17, so that the dust in the ash bucket 16 can be cleaned.
