Drying equipment

Abstract

According to the drying equipment, the two ventilation partition plates are adopted to divide the interior of the box body into the air inlet area, the drying area and the air exhaust area, so that hot air from a heat pump unit reaches the drying area through a plurality of small round holes in the ventilation partition plates, and hot air in the drying area enters the air exhaust area through a plurality of small round holes in the ventilation partition plates, and therefore the drying efficiency is improved. Hot air in the drying area can flow more slowly and uniformly; due to the fact that the multiple draught fans are further arranged on the upper portion of the drying area, the air outlet direction of the draught fans is consistent with the hot air circulation direction of the heat pump, the circulation air volume in the drying area can be increased, and therefore the temperature and the humidity in the whole drying area can be more uniform. When the drying equipment is used for drying the paper, due to the fact that the temperature and the humidity in the whole drying area are more uniform, a better drying effect can be achieved, the conditions that the paper is curled, wrinkled and the like in the drying process are effectively avoided, and the yield of the paper is improved.

Description

technical field [0001] The invention belongs to the technical field of material drying, and in particular relates to a drying equipment. Background technique [0002] In the production process of paper, it is necessary to dry the produced paper to fully evaporate the moisture in the wet paper, so as to obtain a flat and dry finished paper. In the prior art, the wet paper is usually placed on the assembly line and passed through The electric heating wire and the fan form hot air, and the wet paper is dried by the hot air. [0003] Although the existing equipment can dry paper, there are still many problems: first, the wet paper on the assembly line is often heated unevenly, and some paper will appear wrinkled, resulting in a low yield; second, the paper has A variety of different types and different thicknesses need to be dried by different processes. When switching the type of paper to be dried, manual monitoring and adjustment is often required, which is time-consuming and...

[0003] Although the existing equipment can dry paper, there are still many problems: first, the wet paper on the assembly line is often heated unevenly, and some paper will appear wrinkled, resulting in a low yield; second, the paper has A variety of different types and different thicknesses need to be dried by different processes. When switching the type of paper to be dried, manual monitoring and adjustment is often required, which is time-consuming and laborious and affects production efficiency; third, during the drying process, the blown out Hot air is exhausted into the air, causing waste of heat energy
