1. The cyclone separation recovery device makes the powder flow rotate, and under the action of centrifugal force, the purpose of separating the powder coating from the air flow is achieved. According to the structure of the cyclone separation type powder recovery device, in order to meet the environmental protection requirements, separate finer powder particles and ensure the cleanness of the exhaust air flow, a secondary filter device needs to be added at the discharge end of the cyclone separation type recovery device.
2. The filter type powder recovery device is to pass the powder airflow through the filter material with certain micropores to achieve the purpose of gas and solid separation, but because the micropores in the filter material are easily blocked, the recovery airflow is reduced, and the recovery effect is reduced. In order to overcome this problem, a pulse backflushing filter device has appeared, which uses pulse backflushing to regularly clean the particles adsorbed in the micropores of the filter material, so as to keep the airflow smooth and maintain a constant recovery effect. According to the size of the powder particles, select the appropriate filter element. Materials, the powder recovery rate can generally reach 98%.
The application of the recovery device of powder coating equipment improves the automation degree of the powder coating process, improves the effective utilization rate of the powder, reduces the pollution of the powder to the atmosphere during the powder coating process and when cleaning the spray booth, and greatly reduces the powder coating process. The labor intensity of the painting process has significantly improved the painting labor productivity.
