A system for producing fine rubber powder from waste tires

Abstract

The invention discloses a system for preparing fine rubber powder by utilizing a waste tire. The system comprises a tire pulverizing unit, a regenerative restoration unit and a plasticizing unit, wherein a tire circle cutting machine, a tire crusher, a rubber block shredding machine, an exciting magnetic separator, a colloidal particle shredding machine and a rubber pulverizer, which are sequentially connected with one another, are arranged on the tire pulverizing unit; the regenerative restoration unit comprises an ingredient metering mechanism, a material mixing mechanism, a forcible quantitative feeding mechanism, a heating mechanism and a desulfurization mechanism; the plasticizing unit comprises a refiner and a rubber filtering forming machine; a storage unit is arranged between the pulverizing unit and the regenerative restoration unit, and comprises at least three storage tanks which are arranged in the vertical direction; a buffer unit for controlling the feeding speed of the plasticizing unit is arranged between the regenerative restoration unit and the plasticizing unit, and comprises a tank body; a transmission shaft is arranged in the tank body; a spiral blade for advancing the material to the plasticizing unit is arranged on the transmission shaft. According to the system, continuous operation is realized; the layout is reasonable; the work efficiency is improved; and the quality is also ensured.

Description

technical field [0001] The invention belongs to the technical field of manufacturing equipment for processing waste tires and rubber, and in particular relates to a system for preparing fine rubber powder from waste tires. Background technique [0002] With the improvement of living standards, more and more people use cars to travel, and the number of cars is increasing year by year. After the replacement of cars, a large number of waste tires are produced. Recycling waste tires can not only alleviate the pollution pressure on the environment, but also can Realize the reuse of resources. The existing waste tire recycling method is mainly to mechanically crush waste tires into rubber powder. The processed rubber powder cannot be made into recycled rubber production sheets without desulfurization treatment, and its application range is narrow. At present, the desulfurization system of rubber powder is usually set up separately, which cannot realize continuous production. Duri...

Problems solved by technology

The existing waste tire recycling method is mainly to mechanically crush waste tires to make rubber powder. The processed rubber powder has not been desulfurized and cannot be made into recycled rubber production sheets. The application range is narrow

At present, the desulfurization system of rubber powder is usually set up separately, which cannot realize continuous production. During the transfer of rubber powder, there will be loss or even quality decline, and the production efficiency is low.
