Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0016] Such as figure 2 As shown, the exhaust fan 2 installed above or on the side of the spray chamber 1 draws the air floating with 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 pass it through the pipe 4. In the powder settling chamber 5, at the upper end of the powder settling chamber 5, one or more humidifiers 6 are installed to continuously spray water vapor to the gas and powder entering the chamber, so that the powder agglomerates and sinks to the bottom of the settling chamber, and then through The pipeline 7 enters the drying room 8 where it is heated and dried to obtain dry powder paint for reuse.

[0017] The exhaust fan 2 is installed above or on the side of the spray chamber 1 and has a trumpet shape and opens to the spray chamber to increase the a...

Abstract

The invention discloses a recycling system in a thermosetting powder coating spray chamber. The recycling system in the thermosetting powder coating spray chamber comprises an air draft device, a cyclone centrifugation device, a powder settling chamber, a humidifier and a drying chamber, the inlet of the air draft device is connected with the spray chamber, the outlet of the air draft device is connected with the inlet of the cyclone centrifugation device, the outlet of the cyclone centrifugation device is connected with the inlet of the powder settling chamber, the humidifier is located at the upper end of the powder settling chamber, and the outlet of the powder settling chamber is connected with the inlet of the drying chamber. The recycling system in the thermosetting powder coating spray chamber recycles the residual powder coating in spraying and separates the powder which can be used again, the residual powder coating is avoided from being directly discharged into the atmosphere, the repeating utilization factor of the product is effectively improved, and the environmental protection property of the product is improved in constructing.

Description

technical field [0001] The invention relates to a powder paint recovery technology, in particular to a recovery and reuse system in a thermosetting powder paint spray chamber. Background technique [0002] During the spraying process of thermosetting powder coatings, most of the powders are charged and attached to the workpiece, and some powders are floating in the air, which are not effectively utilized, and even directly discharged into the atmosphere, polluting the environment, so it is necessary to deal with them during the spraying process. The powder coating remaining in the air is 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...
