AI Technical Summary
The existing wet air hood is prone to blockage on the outside of the dryer of the paper machine due to moisture bonding, and after the wet air condenses and dews, it may fall on the paper to form drip, affecting the quality of the paper.
Design a kind of wet air mask anti -tie -free dew, including the main body of drying cylinder, the inner wall of the airmaker, the cylinder spray box, the removable activity of the curtain box and the wet box. The second is to use the hot air to blow out the moisture to reduce dripping and increase the ability to absorb moisture.
Effectively isolate airflow inner and outer airflows, prevent wet air from entering the air mask, reduce exposure and dripping water, improve the quality of paper products, and facilitate cleaning inside the air duct to prevent blockage.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A device for preventing condensation and dripping of a wet part air hood comprises a drying cylinder body and an inner wall of the air hood, a plurality of cylinder spray boxes are arranged between the drying cylinder body and the inner wall of the air hood, a detachable movable air curtain box is installed at the bottom between the drying cylinder body and the inner wall of the air hood, a dehumidification box is arranged on the lower surface of the movable air curtain box, and a dehumidification duct is opened on the front side of the dehumidification box.
[0006] As a preferred technical solution of the utility model, a portal axis type fixing frame is provided on the right side of the movable air curtain box, and the movable air curtain box is installed on the outer surface of the drying cylinder body through the portal axis type fixing frame.
[0007] As a preferred technical solution of the utility model, a lock hole is provided on the left side of the movable air curtain box, and a latch for fixing the movable air curtain box is inserted into the lock hole.
[0008] As a preferred technical solution of the utility model, the upper surface of the movable air curtain box is provided with a plurality of first air ducts in a straight line shape.
[0009] As a preferred technical solution of the utility model, the dehumidifier box is specifically an inverted trapezoidal structure, and second air ducts are opened on both the left and right sides of the dehumidifier box.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The device isolates the air flow inside and outside the air hood, and also blocks the possibility of water vapor entering the air hood to form dripping; the movable air curtain box is easy to open, which increases the convenience for cleaning the inner air duct in the future; after the movable air curtain box and the dehumidification box are combined into one, dripping is reduced and the ability to absorb moisture is increased. In summary, the device is convenient for cleaning the inside of the air duct, preventing the blockage of the spray hole and the flow channel, avoiding the entry of wet air into the air hood, and preventing the wet air from condensing and dripping on the paper, thereby improving the product quality of the paper.
