Spiral mixing type carbon black granulator

Abstract

The invention relates to the technical field of carbon black pelletizers, in particular to a spiral mixing type carbon black pelletizer which comprises a base table, a pelletizing cylinder, a horn mouth, a stirring assembly and a screening assembly. Carbon black particles are screened through screening holes, hardened particles or particles with too large diameters can be effectively filtered out, and thus the quality of a product produced by the spiral material mixing type carbon black granulator is guaranteed. Carbon black particles are stir-fried through a stirring plate and are stirred and rounded again in the process of screening the carbon black particles, so that the carbon black particles are fuller, and a slide is arranged at the bottom end of a leaking hole, so that the processed carbon black particles can roll down along the slide, and the particles are prevented from directly falling off and being crushed, so that the protection of the spiral mixing type carbon black granulator on the produced particles is improved.

Description

technical field [0001] The invention relates to the technical field of carbon black granulators, in particular to a spiral mixing type carbon black granulator. Background technique [0002] Carbon black is a light, loose and extremely fine black powder, and has the characteristics of small particle size, large specific surface area, low hardness, low heat generation, high elasticity, small denaturation, flex resistance, and good processing performance. A large amount of filling can improve the processing performance of the rubber compound, shorten the mixing time, improve the dimensional stability of the product, reduce the compression permanent change, increase the adhesion between the rubber compound and other materials and improve the appearance quality of the product. Therefore, it is widely used Used in various natural rubber, styrene-butadiene rubber, nitrile rubber, butadiene rubber, butyl rubber, neoprene and other rubber products. However, in actual use, powdered ca...

Problems solved by technology

[0002] Carbon black is a light, loose and extremely fine black powder, and has the characteristics of small particle size, large specific surface area, low hardness, low heat generation, high elasticity, small denaturation, flex resistance, and good processing performance. A large amount of filling can improve the processing performance of the rubber compound, shorten the mixing time, improve the dimensional stability of the product, reduce the compression permanent change, increase the adhesion between the rubber compound and other materials and improve the appearance quality of the product. Therefore, it is widely used Used in various natural rubber, styrene-butadiene rubber, nitrile rubber, butadiene rubber, butyl rubber, neoprene and other rubber products. However, in actual use, powdered carbon black has poor fluidity and is easy to fly, which is not conducive to transportation And use, in order to solve this problem, carbon black needs to be granulated. At present, carbon black is usually granulated by a granulator

[0003] However, there is a big problem in the existing carbon black granulator in use. The existing carbon black granulator is not convenient enough to add raw materials, and it is easy to cause leakage of raw materials, increase the loss of raw materials, and increase the production cost. The use cost of the granulator. During the processing of the existing carbon black granulator, the feed port is not covered, which is easy to cause carbon black dust to scatter, causing dust pollution. The existing carbon black granulator cannot be added at any time Granulation water is not conducive to the flexible adjustment and control of the granulation process, thereby reducing the quality of the granules produced by the granulator. The existing carbon black granulator does not screen the completed granules, so that the products produced by the granulator quality varies
