A waste tire recycling device

Abstract

The invention relates to a waste tire recovery device. The waste tire recovery device comprises a crushing device, a collecting device and a waste gas purifying device; the collecting device is arranged at the tail end of the crushing device; the crushing device and the collecting device are both connected with the water gas purifying device; the crushing device comprises a crushing tank; the crushing tank is connected with a driving device capable of driving the crushing tank to rotate around self axis; a heating mechanism is arranged on the crushing tank; multiple crushing cones are formed on the inner wall of the crushing tank; a cover body is arranged at the top end of the crushing tank, and is provided with an exhaust port; the waste gas purifying device is connected with the exhaust port; a discharge port is formed in the bottom of the crushing tank; a valve is arranged in the discharge port; and the collecting device is arranged below the discharge port. The waste tire recovery device crushes waste tires after rubber softening under high-temperature environment, is high in crushing efficiency, long in device life and convenient in use, and cannot cause environmental pollution.

Description

technical field [0001] The invention relates to the field of resource recycling equipment, in particular to a waste tire recycling device. Background technique [0002] Tires are rubber products, which are difficult to degrade under natural conditions. The accumulation of waste rubber occupies land, pollutes the environment, affects the health of residents and is easy to cause fires. Therefore, the disposal of waste rubber products has become a practical problem to be solved urgently by the environmental protection industry and the rubber industry in various countries. Moreover, my country is the world's largest rubber consumer and the world's largest rubber importer. In 2013, my country's tire output was 490 million, and it showed a trend of year-by-year growth. At present, my country has become the second largest rubber manufacturer after the United States. Scrap tire producing countries. Therefore, how to efficiently and environmentally friendly recycle waste tires has b...

AI Technical Summary

Problems solved by technology

[0003] At present, there are generally the following methods for processing waste tires: retreading, burning, thermal splitting, and recycling rubber powder; among them, recycling rubber powder is widely valued by people. To recycle rubber powder, waste tires need to be crushed first, and the rubber fragments and steel wires should be collected separately. Existing waste tire crushing devices usually crush waste tires at room temperature. Since waste tires are relatively hard at room temperature, the crushing efficiency is low, and the wear and tear on the crushing tools is relatively large, so the service life of the crushing device is not long. Frequent replacement of crushing rollers or crushing knives is troublesome, affects production efficiency, and increases production costs
