Description

Technical Field

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

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. The dust scattered during the powder discharge process of the powder coating outlet is directly discharged to pollute the environment, and a dust recovery device is needed to recover the dust.

[0003] A Chinese patent discloses a dust recovery device for a powder coating outlet (authorization announcement number CN213558215U). This patented technology is not only provided with a pretreatment device, which can pre-treat large particles of dust and improve the efficiency of dust separation in the later stage, but also uses electrostatic equipment to adsorb dust in the air, and the recovery efficiency is higher. At the same time, an alarm device is installed. When the device is full of dust, it can remind the staff to recycle, avoiding the staff from repeatedly checking the dust storage box, reducing the workload.

The gas after dust recovery is directly discharged, and a small amount of dust in the gas is discharged to pollute the environment. The completeness of dust recovery is low, and the dust removal on the dust collecting component is inconvenient, which affects the smoothness of dust recovery. Therefore, a person skilled in the art provides a dust recovery device for a powder coating outlet to solve the problems raised in the above background technology. Utility Model Content
