[0002] Welding and grinding are both ways of processing workpieces. Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Grinding is to bring the workpiece into contact with a high-speed rotating friction plate to polish the surface of the workpiece. Oxygen will be produced during welding, and dust-containing gas will be produced during grinding, so a dust removal device is needed to treat the gas.

[0003] Patent document CN220920359U discloses a dust removal device.

[0022] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the utility model: a welding and grinding fume purification and dust removal device;

[0023] It includes a filter cartridge dust collector 8 and a purification component. The output end of the filter cartridge dust collector 8 is installed with a connecting pipe 6, one end of the connecting pipe 6 is connected to a fan 5, a chimney 7 is installed at the output end of the fan 5, and a purification component is installed inside the chimney 7. The purification component is used to purify harmful substances in the flue gas. The purification component includes a purification shell 9, a purification packing layer 10 and a mounting net 11. The purification shell 9 is supported inside the chimney 7, and the purification packing layer 10 is installed inside the purification shell 9. The mounting net 11 is respectively installed at the top and bottom of the purification shell 9, and a pull rod 12 is installed on the top of the purification shell 9;

[0024] The cartridge dust collector 8 is used to treat the gas generated by welding and grinding. After treatment, the gas enters the fan 5 through the connecting pipe 6. The fan 5 transmits the gas to the inside of the chimney 7 and discharges it through the chimney 7. The purification component inside the chimney 7 is used to treat harmful substances in the welding gas. When the gas is discharged from the chimney 7, it will pass through the inside of the purification shell 9. Since a purification filler layer 10 is installed inside the purification shell 9, the harmful substances in the welding gas can be purified through the purification filler layer 10 to avoid environmental pollution caused by gas discharge into the air. The installation net 11 allows the gas to enter the inside of the purification shell 9. Since the purification shell 9 is supported inside the chimney 7 by interlocking, the purification shell 9 can be pulled upward by the pull rod 12, which is convenient for replacing or cleaning the purification component.
