Abstract
The invention provides a coating dryer and an air nozzle special for the coating dryer. The air nozzle special for the coating dryer comprises an air chamber and a straight section, one end of the straight section is communicated with the air chamber, and an air outlet is formed in the other end of the straight section. Compared with a scattered air outlet mode used in an air outlet of a common air nozzle, the coating dryer and the air nozzle special for the coating dryer have the advantages that the straight section is arranged in front of the air outlet of the air nozzle, so that fluid is led to pass through a section of flat channel, due to the fact that sudden size variation of the ventilation section area does not exist in the straight section, eddies can not be caused, a pressure equalizing area can be formed in the straight section instead, and the stability of the speed of air blown out from the air outlet finally is guaranteed. When the air nozzle is applied to the coating dryer, due to the fact that the air speed after pressure equalizing is stable, the air speed enables upward pushing force formed by the air blown out from the air nozzle to foil materials to be stable, the chattering phenomenon of the foil materials can not happen in a drying oven, and the problem that the thicknesses of coatings are not consistent is solved.
