Problems solved by technology
[0007]1. The structure is relatively complex, requiring a large number of blowing pipe groups
[0008]2. Low utilization rate of hot air and high power consumption
[0009]3. Drying only by purging structure leads to poor drying effect, and cannot effectively dry the moisture on the surface of the strip, especially the electric furnace drying equipment
[0010]4. There are many and complicated air pipelines, and most of the existing equipment is open structure, resulting in loud noise during the drying process, especially the steam drying equipment

Abstract
The invention discloses a strip steel drying device, and belongs to the technical field of drying devices. The strip steel drying device comprises a box, a heating structure, a strip steel outlet and a strip steel inlet. The heating structure comprises a first flow guiding box, a second flow guiding box, a first circulating fan, a second circulating fan, a first air channel, a second air channel and a heater, wherein the first flow guiding box is arranged over strip steel, the second flow guiding box is arranged under the strip steel, the heater is arranged in the first flow guiding box, an air inlet of the first flow guiding box is communicated with the air outlet end of the first circulating fan through the first air channel, a first purging structure is arranged on the side, close to the strip steel, of the first flow guiding box, the air draft end of the first circulating fan is communicated with the box (1), an air inlet of the second flow guiding box is communicated with the air outlet end of the second circulating fan through the second air channel, a second purging structure is arranged on the side, close to the strip steel, of the second flow guiding box, the air draft end of the second circulating fan is communicated with the box, the second purging structure carries out forward air outlet, and the included angle between the air outlet direction of the second purging structure and the strip steel ranges from 30 degrees to 45 degrees.
Description
technical field [0001] The invention relates to the technical field of drying equipment, in particular to a strip steel drying device, in particular to a strip steel drying device with high efficiency, low energy consumption, low noise and simple structure. [0002] Background technique [0003] In the process steps of cold-rolled strip steel, the first link is to carry out shelling, pickling, neutralization, cleaning and drying processes on the hot-rolled strip steel. In the drying process, steam drying and electric furnace drying are mostly used at present. Steam drying and electric furnace drying equipment usually consist of a box body, at least one set of heating structures in the box body, and strip steel outlets and strip steel inlets for strip steel entry and exit on the front and rear side walls of the box body. The heating structure usually consists of structures such as heaters, fans and multiple air lines. [0004] For example, the patent application No. 2009202...
