Guide roller type hot air dryer

Abstract

The invention discloses a guide roller type hot air dryer, which comprises a front heating room, a drying room, a rear heating room, a support column, a feeding roller, a sending roller, a centrifugal circulating fan, a steam heater, a drying room wind cover, Active upper guide rollers, passive lower guide rollers, air ducts, air nozzles and exhaust outlets, a drying room is installed on the right side of the front heating room, and a rear heating room is installed on the right side of the drying room. The air cover of the drying room is installed, and the active upper guide roller and the passive lower guide roller are fixed in the drying room. There is an air duct between the active upper guide roller and the passive lower guide roller, and spray nozzles are arranged on both sides of the air duct. The air nozzle is provided with an exhaust port on the right side of the air cover of the drying room. The active upper guide roller and the passive lower guide roller of the guide roller hot air dryer are spread out in the horizontal direction, and the upper and lower center distances are shortened, so that the fabric runs in a W shape in the drying room, with uniform air spray and high drying efficiency. , easy to control, high degree of automation, no need for manual operation, reducing workload and labor.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to a guide roller type hot air dryer. Background technique [0002] In the printing and dyeing industry, because the dye is dissolved in water, the surface of the fabric dyeing liquid contains a large amount of free water, and the dye is prone to "swimming" in the water, which will cause the color difference and defect of the fabric, so it is necessary to use drying equipment , to process the fabric, the defect of the traditional textile drying machine currently used is that the traditional drying equipment cannot fully and thoroughly dry the fabric, the drying efficiency is low, and the air spray is uneven, which reduces the quality of the material. Contents of the invention [0003] The object of the present invention is to provide a guide roller type hot air dryer to solve the problems raised in the above background technology. [0004] In order to achieve the above object, the...
