Air pipe, drying device using same and drying technology thereof

Abstract

The invention discloses an air pipe. The air pipe comprises a first pipe body and a second pipe body which are mutually communicated and not positioned in a same thread. A communicating place of the first pipe body and the second pipe body is provided with a pressure feeding box. The interior of the pressure feeding box is provided with a cavity, and the cavity comprises an air inlet. The air inlet is provided with a pressurizing fan. A box body of the pressure feeding box is provided with a high-temperature heat source. Through the pressure feeding box installed at the communicating place ofthe first pipe body and the second pipe body and the high-temperature heat source on the box body, heat and cold wind is exchanged, wherein there are multiple sources of the high-temperature heat source, for example steam heating, conduction oil heating, and natural gas direct-fired heating, there are multiple modes, operation is conventional and easy, a generated high-temperature gas is used as the high-temperature heat source, a pressure is increased by operation of the matched pressurizing fan so as to form a high-temperature high-pressure wind source, and the high-temperature gas is directly conveyed to the air outlet through pipes of a first air outlet pipe and a second air outlet pipe on the first pipe body and the second pipe body, finally the high-temperature gas is sprayed from atool bore of an air nozzle under a high pressure.

Description

technical field [0001] The invention relates to the field of printing and dyeing drying, in particular to an air duct, a drying device using the air duct and a drying process thereof. Background technique [0002] In traditional printing and dyeing, there is a kind of dyeing technology called "rolling color". Because the traditional color rolling technology is formed by dipping the fabric from the rolling groove by the padding car and rolling off the remaining liquid by the padding car, it is formed by a sizing machine or Other drying equipment is for drying hair color formation. This method is currently the simplest and most effective, but in the subsequent high-temperature color development process, it will cause the finished product to form a color, and the darker the color, the easier it is to form. The main reason is that the plush or gram weight of the high-temperature color development is relatively high. The thick fabric has high humidity, and the surface of the ter...

Problems solved by technology

This method is currently the simplest and most effective, but in the subsequent high-temperature color development process, it will cause the finished product to form a color, and the darker the color, the easier it is to form. The main reason is that the plush or gram weight of the high-temperature color development is relatively high. The thick fabric has high humidity, and the surface of the terry or thick fabric has a high liquid content (traditional drying equipment cannot quickly dry the fabric in a short period of time), it is easy to use the setting machine or other drying equipment. The staining of the chain track or the guide belt forms the color matching of the fabric, so in order to avoid color matching, the traditional color rolling is generally a color rolling line to make a color or several light colors of the same color, so it is urgent for those skilled in the art to solve this problem. question
