Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, the exhaust fan 2 installed above or on the side of the spray booth 1 draws the air floating in the powder coating into the recycling system, and uses the centrifugal effect of the cyclone centrifuge 3 to separate the powder from the air, and passes through the pipeline 4 In the powder settling chamber 5, one or more humidifiers 6 are installed on the upper end of the powder settling chamber 5, continuously spraying water vapor to the gas and powder entering the chamber, allowing the powder to agglomerate and sink to the bottom of the settling chamber, and then The pipeline 7 leads to a drying chamber 8, where heating and drying are carried out to obtain dry powder coatings for repeated use.

[0015] The exhaust fan 2 is installed on the top or side of the spray chamber 1, and is trumpet-shaped, with the open...

Abstract

The invention discloses powder coating recycling and reusing equipment. The powder coating recycling and reusing equipment comprises an air suction device, a cyclonic centrifugal device, a powder sedimentation chamber, a humidifier and a drying chamber, an inlet of the air suction device is connected with a spraying chamber, and an outlet of the air suction device is connected with an inlet of thecyclonic centrifugal device. An air outlet of the cyclonic centrifugal device is connected with an inlet of the powder sedimentation chamber, the humidifier is located at the upper end of the powdersedimentation chamber, and an outlet of the powder sedimentation chamber is connected with an inlet of the drying chamber. According to the powder coating recyclingand reusing equipment, residual powder coating in the coating process is recovered, reusable powder is separated out and prevented from being directly discharged into the atmosphere, the product repeated utilization rate is effectivelyincreased, and environmental friendliness in the product construction process is improved as well.

Description

technical field [0001] The invention relates to the fields of mechanical design and electricity, in particular to a powder coating recovery and reuse equipment. Background technique [0002] During the spraying process of powder coatings, most of the powders are charged and attached to the workpiece, and some powders float in the air and are not effectively utilized, or even directly discharged into the atmosphere, polluting the environment, so the remaining in the air should be dealt with during the spraying process. The powder coatings in it are recycled and reused. At present, the recovery of powder coatings mostly adopts the pulse blowback filter element filter device. The structure of the device is simple, and the filter element needs to be cleaned by a pulse blowback system, which is prone to blockage and seriously affects the recovery efficiency; the filter element is easy to be damaged, and it is often replaced. Cost recovery. Contents of the invention [0003] I...
