A line of drying equipment

Abstract

The invention relates to a drying device for a row line. The drying device comprises an oven used for drying the row line. An exhaust pipeline of the oven extends upwards from the top of the oven. The drying device further comprises a preheating unit which is arranged on the side where a feeding port of the oven is formed and can conduct preheating air drying on the surface of the part, entering the oven in advance, of the row line, a branch pipe used for diverting hot air in the exhaust pipeline to the preheating unit, a containing cavity formed in the periphery of the exhaust pipeline in a surrounding manner, a medium contained in the containing cavity and heated by the hot air in the exhaust pipeline to generate steam, and a transmission pipe communicated with the containing cavity and used for connecting generated steam to other equipment. The containing cavity is close to an air outlet of the oven. According to the drying device for the row line, on one hand, the surface of the row line is preheated and air-dried before entering the oven, meanwhile, waste gas generated in the process of drying the row line through the oven can also be reduced, and therefore a positive circle is formed; and on the other hand, heat energy can be converted into steam to be led into needed equipment, energy is fully utilized, energy saving and emission reduction are reduced, and cost is reduced.

Description

technical field [0001] The invention relates to a line drying equipment. Background technique [0002] As we all know, after the heat treatment of the line, the water on the surface needs to be dried to realize the processing of the line. At present, most of them use an oven, and put the processed line directly into the oven for regular drying. At this time, a large amount of hot gas is generated in the oven, which is directly used as waste gas and discharged to the atmosphere, resulting in a waste of energy. , does not comply with the relevant national regulations on energy conservation and emission reduction, and at the same time, the processing cost of the line is also relatively high. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the object of the present invention is to provide an improved line drying equipment. [0004] In order to achieve the above object, the present invention provides a line drying equipment, which i...
