Hot-air drier

Abstract

The invention discloses a hot-air drier, comprising a heat-retaining housing, and drying cylinder columns, hollow drying cylinders, a radiator, a circulating blower fan, a circulating wind adapter, a hot-air channel, a pipe and an electrostatic dehydrator which are arranged in the heat-retaining housing. The heat-retaining housing has a feed inlet and outlet. More than one pair of drying cylinder columns are distributed in the heat-retaining housing, two rows of high-low staggered hollow drying cylinders are arranged between each pair of drying cylinder columns. The hollow drying cylinders are driven by a transmission mechanism. At least one radiator for heat generation is arranged in the heat-retaining housing. The circulating blower fan driven by the motor frequency conversion control is arranged on the radiator. The hot-air channel is hollow and provided with a hot-air nozzle. The circulating wind adapter is connected with the circulating blower fan and the hot-air channel. The electrostatic dehydrator is connected with the radiator through the pipe, the electrostatic dehydrator is used for absorbing the stream, filtering out water and sending air to the radiator by the pipe to form a circulation. The invention has lower cost, environmental protection, energy conservation, safety and the like.

Description

technical field [0001] The invention relates to textile drying technology, in particular to a hot air dryer. Background technique [0002] Existing dryers for weaving generally adopt steam dryers. The steam dryer has a plurality of drying cylinder columns, and a plurality of steam drying cylinders are respectively fixedly arranged with bearings between the drying cylinder columns. The steam dryer is a hollow cylinder that holds high-temperature steam, so it is made of materials with strong pressure resistance and good heat transfer, and the wall of the cylinder has a certain thickness. The cloth is sequentially conveyed on the steam dryer, and the cloth is dried by the high temperature of the steam dryer. [0003] The steam dryer is an open structure, and the steam drying cylinders are all exposed, so that the whole working process can be directly observed. However, each steam cylinder of the steam dryer is in a high temperature state, and the entire steam dryer emits a l...

AI Technical Summary

Problems solved by technology

However, each steam cylinder of the steam dryer is in a high temperature state, and the entire steam dryer emits a lot of heat, resulting in extremely high temperatures in the entire workshop, especially in hot summer, when the physical strength of the staff is high. And long-term exposure to harsh environments is not conducive to health

[0004] At the same time, so much heat is dissipated, virtually causing serious waste of resources

For enterprises, increased cost investment

[0005] In addition, the steam is in a state of high temperature and high pressure, and the staff need to be very careful. If there is a slight misoperation, they will be scalded by the steam or the steam dryer. Therefore, the existing steam dryer still has potential safety hazards.
