[0030] When using the dust removal device, first put the workpiece that needs to be dusted on the vibrating conveying mechanism 5 on the dust removal workbench 1, and the vibrating conveying mechanism 5 drives the workpiece to move. After the workpiece enters the dust removal box 2, the control device 3 controls the dust removal mechanism 4 to remove dust from the workpiece. At the same time, the dust removal mechanism 4 drives the vibrating conveying mechanism 5. When the vibrating conveying mechanism 5 moves the workpiece, the vibrating conveying mechanism 5 drives the workpiece to vibrate, and the workpiece shakes off the dust on the surface. Then, when the workpiece passes through the dust removal mechanism 4, the dust removal mechanism 4 sucks away the dust on the workpiece, and then the workpiece is conveyed by the vibrating conveying mechanism 5. The workpiece is moved out of the dust removal box 2 under the action of the vibration conveying mechanism 5, and then moved to the spraying equipment for spraying operation. The workpiece is moved to the dust removal box 2 by utilizing the vibration conveying mechanism 5.

At the same time, under the vibration of the vibration conveying mechanism 5, the workpiece can vibrate during the movement, so that the dust on the surface of the workpiece can be shaken off, further improving the effect of removing dust from the workpiece.

[0032] When the workpiece moves into the dust removal box 2, the workpiece first passes through the soot blowing assembly 45, which blows off the dust on the surface of the workpiece. At the same time, the suction assembly 44 is used to allow the suction pipe 43 to generate suction, so that the dust suction nozzle 42 on the dust removal pipe 41 sucks the dust on the surface of the workpiece and the dust blown up by the soot blowing assembly 45. The workpiece passes through the dust suction nozzle 42 on the dust removal pipe 41, and then the workpiece moves out of the dust removal pipe 41, completing the removal of dust on the surface of the workpiece. When the workpiece enters the dust removal box 2, the workpiece passes through the dust suction nozzle 42 on the dust removal pipe 41, and the dust suction nozzle 42 sucks away the dust on the surface of the workpiece, so that the dust on the surface of the workpiece can be removed quickly and conveniently, reducing the possibility that dust adhering to the surface of the workpiece affects the spraying quality of the workpiece.

The soot blowing blades 454 suck the outside air into the air supply pipe 453, and then blow it out from the soot blowing nozzle 452 on the soot blowing pipe 451. The soot blowing nozzle 452 blows up or blows off the dust on the workpiece, and the soot blowing nozzle 452 faces the dust removal nozzle 42. When the dust is blown up or blown off, the dust removal nozzle 42 sucks the dust away. By using the soot blowing nozzle 452 to blow air on the surface of the workpiece when the workpiece passes through the soot blowing pipe 451, the dust on the surface of the workpiece can be easily blown up or blown off, thereby further reducing the possibility of dust adhering to the workpiece and improving the dust removal efficiency of the dust removal nozzle 42.
