Description

Technical Field

[0001] The utility model belongs to the technical field of rubber temperature control, and particularly relates to an automatic temperature control device for a rubber raw material drying room. Background Art

[0002] Rubber is a very important industrial material, widely used in many fields such as tires, rubber shoes, hoses, tapes, seals, etc. In the production process of rubber products, the drying of raw materials is a very important step. The main reasons are as follows: Rubber raw materials need to be dried before production to remove moisture. Because rubber is a highly hygroscopic material, if the raw materials contain too much moisture, it will cause deformation, cracking, aging and other problems in the products, affecting the quality and service life of the products. Drying can improve the processing performance of rubber raw materials. Because moisture affects the plasticity and viscosity of rubber, it makes it difficult to process rubber into the required shape and size. During the production process of rubber products, they will be affected by various external factors, such as temperature, humidity, oxygen, etc., which may cause aging and degradation of rubber. Through drying treatment, the hygroscopicity of rubber products can be effectively reduced, and their durability and stability can be improved, thereby extending the service life of the products. The original radiator of the rubber drying room was installed below the ground, and an iron plate was laid on the top. The heat generated by the heating system was heated by the iron plate on the ground edge to dry the rubber. The existing drying method has the problems of large steam consumption, uneven temperature in the drying room, and affecting the heating quality of the rubber. Utility Model Content
