Description

Technical Field

[0001] The utility model relates to the technical field of powder coating dust removal, in particular to a powder coating dust removal device for production. Background Art

[0002] Powder coating refers to a new type of solvent-free 100% solid powder coating. Different from the form of general coating, it exists in the state of fine powder. Since no solvent is used, it is called powder coating. Powder coating is harmless, efficient, resource-saving and environmentally friendly. Powder coating will inevitably generate a lot of dust during the production process. In the dust removal process, the existing dust removal device absorbs the air containing dust particles in the production workshop and the powder particles on the production equipment into the dust removal device. In the patent with application number 202022423530.0, "a dust removal device for powder coating production is disclosed, including a device shell, a dust collecting port is opened on one side of the device shell, a dust collecting hood is fixedly installed on the outside of the dust collecting port, a fan is fixedly installed on the inner side of the device shell located on the dust collecting port, a filter plate is obliquely installed in the dust collecting hood, a dust collecting box is fixedly installed at the bottom of the dust collecting hood, and the dust collecting box is connected to the dust collecting hood."

[0003] The above-mentioned document facilitates the direct recycling of dust particles and powder particles. However, when collecting dust particles, the clogging of the filter plate is not taken into consideration, and the dust removal effect is inefficient. In addition, the air flow into the device housing cannot come out quickly, so that the dust particles and powder particles absorbed at the dust collecting port cannot be brought into the device housing with the air in time. Therefore, improvements are needed. Utility Model Content
