Description

Technical Field

[0001] The invention relates to the field of mechanical equipment, and in particular to a waste tire comprehensive treatment system based on ultra-high pressure water jet technology. Background Art

[0002] my country is a major tire manufacturer and consumer. The amount of rubber consumed in tire production accounts for 70% of the country's total rubber consumption each year. 80% of natural rubber and 30% of synthetic rubber required by the rubber products industry rely on imports. As the industry develops, a large number of waste tires are produced. According to statistics, more than 60% of my country's waste rubber comes from waste tires, and only 20% of the recycled waste rubber is from waste tires. The increasing amount of waste tires not only occupies space resources, but also easily causes environmental pollution. Therefore, the recycling of waste tires is of great significance to the sustainable development of industry.

[0003] The main methods for recycling waste tires include retreading, thermal energy utilization and making rubber powder. Among them, retreading technology is generally used for bias tires, while there are still great difficulties in retreading radial tires, which are the most commonly used tires on the market. Thermal energy technology utilization will cause secondary pollution to the environment during the recycling process due to the immaturity of the technology and the recycling value is very low.

[0004] Waste tires are crushed into rubber powder and then used in industrial production. The recycled products in this way are of high value and have no secondary pollution. Therefore, making rubber powder from waste tires is a very promising recycling method. In the prior art, the methods for processing waste tires into rubber powder mainly include freezing method, chemical method, mechanical method and water jet method. Due to the high cost, freezing method and chemical method are rarely used in industrial production; the rubber powder produced by mechanical method has limited mesh size, and it is difficult to obtain high-value recycled products, and the development space is greatly limited. As a purely physical process, high-pressure water jet technology will not destroy the internal structure of the material. It can fully crack the tires under a certain pressure to obtain high-value rubber powder with high mesh size. At the same time, the water used can be recycled and reused. The whole process is pollution-free and waste-free. Therefore, the water jet method is the most promising method for recycling waste tires.

[0005] At present, there are many related technologies, such as the published Chinese patents 200610096128.8, a method and equipment for preparing rubber powder using waste tires based on water jet technology, 200820073797.8, equipment for preparing rubber powder using waste tires, 201310611880.1, waste tire recycling method and mechanism, etc. These devices only mention the process of making waste tires into rubber powder, and do not consider the reasonable operation and layout of the entire system in the production process.

[0006] Therefore, it is necessary to provide a waste tire comprehensive treatment system based on ultra-high pressure water jet technology to overcome the above-mentioned defects. Summary of the invention
