Description

Technical Field

[0001] The utility model relates to the technical field of rubber production, in particular to a rubber raw material heating device used in rubber production. Background Art

[0002] In the process of rubber preparation, the rubber raw materials need to be proportioned first, then the proportioned raw materials are preheated and mixed, and then processed and formed through cable extrusion equipment.

[0003] The utility model patent with the publication (announcement) number CN213500144U solves the problem of the existing heating and mixing device, which is that the feeding and discharging are inconvenient, and the mixing effect is poor, and it is difficult to meet the requirements of mixing and uniform preheating. The utility model patent adopts a conveyor belt to feed the rubber raw materials at a uniform speed. When the rubber raw materials move slowly and uniformly along the conveyor belt to one side of the flip door, the flip door flips under the push of the rubber raw materials, so that the rubber raw materials enter the reactor. Among them, the excess heat generated by the heating in the reactor is sequentially discharged from the suction hood along the air pipe to the outlet hood. Internal blowing can better preheat the rubber raw materials in the feed box. Stirring paddles are symmetrically welded on the outside of the rotating shaft, and scrapers are welded between the stirring paddles. One side of the scraper is in friction contact with the inner wall of the reactor, which can reduce the adhesion of the rubber raw materials to the inner wall of the reactor. This method has a simple structure, but in actual use, part of the rubber raw materials will accumulate in the discharge pipe. This part of the rubber raw materials cannot be heated and stirred, which leads to poor heating effect. Therefore, it is necessary to design and modify the rubber raw material heating equipment for rubber production to effectively prevent the phenomenon of poor heating effect. Utility Model Content
