[0001] The present invention relates to the technical field of dust removal equipment, and in particular to a spraying dust removal equipment for explosion protection in a dust spraying workshop. Background Art

[0002] The dust spraying workshop is mainly used to evenly coat the surface of workpieces with powder coatings through electrostatic spraying technology, and is widely used in industries such as metal products, household appliances, and automotive parts.

[0003] Electrostatic spraying refers to a coating method in which atomized paint is negatively charged under the action of a high-voltage direct current electric field by using the principle of corona discharge and is adsorbed on the surface of a positively charged substrate for discharging. The electrostatic spraying equipment consists of a spray gun, a spray cup, an electrostatic spraying high-voltage power supply, etc.

[0004] However, the dust generated during the current powder spraying process not only affects the workshop environment but may also cause safety accidents such as explosions. At the same time, the spraying workshop often uses simple ventilation fans for ventilation. After the ventilation fans are used for a long time, powder will adhere to the surface of the fan blades, which is prone to clogging, greatly reducing the ventilation efficiency, being unfavorable for powder dust removal, and greatly increasing the danger coefficient of the workshop.
