Description

Technical Field

[0001] The utility model relates to the technical field of air selection and drying equipment, in particular to air selection and drying equipment for powder type coatings. Background Art

[0002] Powder coating is a solid granular coating, usually composed of resin, pigment, additives and filler. It is adsorbed to the surface of the coated object through the action of static electricity or friction charge, and then melts during the baking process to form a solid coating. Air separation and drying is an important step in the powder coating coating process, but traditional air separation and drying equipment has a single function and a simple structure. On the one hand, it cannot maintain a certain temperature inside the device to save energy for the next drying work. On the other hand, it cannot adjust the falling speed of the powder coating to adjust the amount of dried powder coating. Therefore, those skilled in the art provide an air separation and drying device for powder coating to solve the problems raised in the above background technology. Utility Model Content

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. Turn the sealing cover to separate it from the feed pipe, then pour the powder coating from the feed pipe into the feed box, and then turn the sealing cover again to combine it with the feed pipe. This operation is beneficial to prevent the entry of external dust on the one hand, and to prevent the loss of internal heat on the other hand. The powder coating in the feed box enters the interior of the discharge box through the third filter plate, and then enters the interior of the lower movable ring and the upper end of the second filter plate through the first filter plate on the upper fixed ring, and finally falls into the interior of the insulation box.
