11. Internal epoxy powder coating equipment:

In the spraying operation, after the upper part of the workpiece, the inner spray gun is inserted into the steel pipe until the entrance position of the spray chamber, and the inclined wheel rotates to make the workpiece rotate and advance horizontally. After the intermediate frequency is heated to about 200 °C and reaches the position of the spray chamber, the inner and outer spray guns are sprayed. The workpiece is sprayed and the heat is applied to solidify the powder. When the workpiece exits the spray chamber for about 1.5-2 minutes, it enters the water cooling station, and after cooling, it is transported to the lower part of the lower platform by the inclined wheel. After the workpiece is sprayed, the inner spray gun retreats by about 14m , and the upper part repeats the work. The excess powder generated during the external spraying process is reused in the recovery system, and the cyclone + capped filter recovery device is used for recycling. The recovery fan is 4-72-4#/5.5KW . The recycling is secondary recovery, the cyclone collects most of the powder, and a small amount of powder enters the filter recovery, which not only reduces the filter load, but also ensures the discharge environment.
