Rotary screen dryer

Abstract

The invention relates to a rotary screen dryer which comprises a rack and a rotary screen, wherein the rotary screen is mounted in the rack through a rotating shaft, a suction fan is arranged at the right end of the rotary screen and mounted on the rack, an opening is formed in the right end of the rotary screen, an air guide pipe is mounted at the opening, upper and lower ventilation openings are formed in the air guide pipe, air uniformizing plates are arranged at the upper end and the lower end of the rotary screen, a plurality of through holes are formed in the air uniformizing plates, air deflectors are arranged between the upper end and of the rack and one air uniformizing plate as well as between the lower end of the rack and the other air uniformizing plate, and radiators are arranged at the upper and lower ventilation openings of the air guide pipe. The rotary screen dryer is simple in structure, the air deflectors are arranged outside the air uniformizing plates, so that hot air can blow to fabric uniformly, and the quality stability of the fabric is guaranteed.

Description

technical field [0001] The invention relates to a rotary screen dryer, which belongs to the technical field of drying devices for nonwoven fabric processing equipment. Background technique [0002] Rotary mesh dryer is one of the main equipment in the production process of nonwoven fabrics. It is widely used in drying and setting in various nonwoven fabric production processes such as spunlace, spunbond, hot rolling, and needle punching. It is also used for Drying of loose fibers and knitted fabrics. It uses the principle of hot air penetration to wrap the fabric on the surface of the rotary screen, the hot air blows to the fabric and penetrates the fabric into the rotary screen, and then the hot and humid air in the rotary screen is sucked away by the suction fan, and the hot and humid air is radiated After being heated by the device, it is blown to the fabric again, and the hot air can be recycled. [0003] The existing rotary screen dryer is only equipped with a uniform...

AI Technical Summary

Problems solved by technology

[0003] The existing rotary screen dryer is only equipped with a uniform air plate, the opening ratio of the air uniform plate is uniform, and the hot air is unevenly distributed at the left and right ends of the rotary screen and in the middle, resulting in different penetration capabilities of the hot air, resulting in hot air generation Different pressure blows to the fabric, resulting in uneven drying at the left and right ends of the fabric and in the middle, resulting in unstable product quality
