Description

Technical Field

[0001] The present application relates to the technical field of mixing equipment, and in particular to explosion-proof silicone mixing equipment. Background Art

[0002] In the production of high-tear resistant silicone rubber cable material products, fumed silica is the main raw material. Mixing equipment is required for the production of fumed silica. When the equipment is running, the liquid base rubber and fumed silica powder rub against each other under extremely high shear force, generating high temperature. The high temperature will destroy the chemical structure of the silicone and release combustible gas and heat. When these conditions accumulate to a certain extent, it may cause an explosion.

[0003] In order to solve the above problems, the Chinese patent with the authorization announcement number CN209237753U discloses a silicone kneader for silicone processing, which discloses that a cooling layer is processed inside the kneading shell, and a cooling device is provided in the cooling layer. The cooling device includes a group of cooling pipes, which are spirally arranged in the cooling layer inside the kneading shell. One end of the cooling pipe is connected to a cooling water source through a pipe, and the other end of the cooling pipe is connected to a recovery box. The cooling device is provided inside the kneading shell to quickly cool the kneading shell, and the kneader is cooled by water circulation cooling to reduce the risk of explosion. However, after the water is heated, scale is easily generated inside the water. These scales will enter the recovery box with the water flow when the water circulates. When reused, these scales will enter the cooling layer again. Some scales are easily attached to the inner wall of the cooling layer, affecting its heat dissipation effect. Therefore, an explosion-proof silicone mixing equipment is proposed to solve the above problems. Summary of the Invention
