Fully-automatic plasticizing rubber powder premixer

Abstract

The invention discloses a fully-automatic plasticizing rubber powder premixer which comprises an adjuvant supplying device, a waste rubber powder supplying device and a blending device, wherein the adjuvant supplying device comprises an adjuvant homogenizing box in which an adjuvant stirring device and an adjuvant heating device are mounted, wherein the viscosity of various adjuvants such as a softener and an activator is decreased in a heating state, so that the adjuvants are evenly mixed in the adjuvant homogenizing box; only a homogenized adjuvant waste rubber powder dough is just formed in a stirrer after the hot adjuvants are added, so that the adjuvants can be homogenized in the waste rubber powder dough in a stirring manner; meanwhile, the homogenized adjuvants added into the stirrer are hot, namely, the hot homogenized adjuvants can be used for transferring the heat into the waste rubber powder, so that the fluidity of the homogenized adjuvants is maintained. Thus, the adjuvants are fully homogenized in the waste rubber powder. Therefore, the waste rubber powder can fully react in a desulfurizing process. As a result, the quality of regenerated rubber powder is greatly improved, namely, the regenerated rubber powder has a wider application prospect.

Description

Technical field [0001] The invention relates to an equipment for processing waste rubber. Background technique [0002] In recent years, my country’s annual production of waste tires has increased by 8% to 10%. In 2012, the amount of waste tires produced in my country reached about 300 million, and the recycling rate was only about 50%, less than 30% of Western developed countries, resulting in a huge waste of resources. Desulfurization of waste rubber to make recycled rubber is one of the best treatment methods. [0003] The disadvantages of traditional high-pressure desulfurization tanks are: continuous production is not possible, production efficiency is low, and safety accidents are easy to occur; there are also continuous desulfurization equipment, such as patent 201210419638.X discloses an automatic desulfurization machine, which solves the shortcomings of high-pressure desulfurization tanks. However, the quality of the reclaimed rubber powder produced during the use proces...

In 2012, my country's waste tire production amounted to about 300 million pieces, and the recycling rate was only about 50%, which was less than 30% of that in western developed countries, resulting in a huge waste of resources

[0003] The disadvantages of traditional high-pressure desulfurization tanks are: continuous production is not possible, production efficiency is low, and safety accidents are prone to occur; there are also continuous desulfurization equipment, such as patent 201210419638. However, the quality of reclaimed rubber powder produced during use is not high. The reason is that
