Description

Technical Field

[0001] This utility model belongs to the field of cable material processing technology, and in particular relates to a vacuum dryer for manufacturing cable materials. Background Technology

[0002] A vacuum dryer is a low-temperature device that heats materials under vacuum. Vacuum dryers are used for dehydrating and drying high-value-added and heat-sensitive agricultural and sideline products, health products, food, medicinal herbs, fruits and vegetables, and chemical raw materials; for low-temperature concentration of chemical products, removal of water of crystallization, drying of enzyme preparations, and vacuum extraction of traditional Chinese medicine; and are suitable for experiments in scientific research institutions. In the manufacturing process of cable materials, a step requires vacuum drying of the cable material particles, which necessitates the use of a vacuum dryer.

[0003] However, existing vacuum dryers typically heat and evaporate or sublimate the moisture in cable materials, and the water vapor is then condensed and recovered by a condenser. This means that the heat in the water vapor is directly transferred to the condensate in the external condenser, which not only makes this part of the heat unusable but also wastes it. To address this, we propose a vacuum dryer for manufacturing cable materials. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum dryer for manufacturing cable materials. By setting up a recovery section, specifically due to the setting of a one-way valve, water vapor only enters the second pipe. The heat in the water vapor is transferred to the cable material through the one-way valve and the drying cylinder. The water vapor first flows from the top to the bottom of the second pipe, then from the bottom to the top of the one-way pipe, and re-enters the second pipe. When the water vapor cools down, the outlet valve is opened, and cooling water flows out. The heat in the water vapor is reused, effectively avoiding the waste of heat. This solves the problem that in existing vacuum dryers, after heating and evaporating or sublimating the moisture in the cable material, the water vapor is condensed and recovered by a condenser. In this case, the heat in the water vapor is directly transferred to the condensate in the external condenser, which not only makes this part of the heat unusable but also wastes this part of the heat.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
