Fully automatic plasticized 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 a device for processing waste rubber. Background technique [0002] In recent years, the annual waste tires produced in my country have been increasing at a rate of 8% to 10%. 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. 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 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 the softener, activator, and waste rubber powder are respectively...

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 the softener, activator, and waste rubber powder are respectively added to the stirring device and stirred and mixed at room temperature, because the viscosity of the softener and activator is relatively high. , will form softener waste rubber powder and activator waste rubber powder, even if it is fully stirred, it will be difficult to fully homogenize, so that the automatic desulfurization machine will not react fully during the desulfurization process, and the quality of reclaimed rubber powder is not high, which is also a constraint on waste Major Technical Difficulties in Rubber Treatment
