Abstract

This invention relates to a decomposition method of tire scrap, comprising the following steps large crushing treatment, small crushing treatment, coarse degumming treatment, and fine degumming treatment. The large and small crushers are used to effectively crush the scraps into fine rubber fragments. The degumming machine is applied cooperatively to decompose the adulterated steel wires in the rubber fragments. Furthermore, the magnetic separator is applied cooperatively to attract and sieve the decomposed steel wires. Accordingly, the cut scrap during the manufacturing process of tire can be decomposed to form rubber for the industry to recycle.

Description

Decomposition method from tire scrap

The invention relates to a method for decomposing a scrap, in particular to a method for decomposing from a tire scrap.

According to the progress of the industrial age, tires are widely used in the transportation industry. In particular, vehicles are one of the main means of transportation in modern society, and are filled with all walks of life and daily life, making tires indispensable for today's life. When the material is consumed, and the tire is used for a long time, the internal structure will be aging. At this time, it cannot be used any more, so it will be replaced and the dealer will recover the decomposition action, so that the waste tire can be used by the pulverizer and The magnetic separator decomposes the rubber material and recycles it. However, in the manufacturing process of the tire, the main processes can be divided into five major processes: “refining→extruding→calendering→cutting→sulfurizing”. The tires are made of sulfur. Before the birth, the tire system must be cut off to remove the waste outside the size. The scraped scrap has steel wire and is not vulcanized, which makes the tire waste soft and not easily decomposed and recovered, and the manufacturer cannot directly recycle it. Recycling, the recycling of tires is limited to the decomposition of waste tires, and the scraps cut during the tire manufacturing process can only be discarded, resulting in the original Destroyer waste and environmental materials.

In view of this, the inventors have been engaged in the manufacture, development and design of related products for many years, and have made the invention effective in view of the above-mentioned target inspection, detailed design and prudent evaluation.

According to the tire, before the vulcanization, the green tire system must be cut and processed to remove the waste outside the size. The scraped scrap has steel wire and is not vulcanized, which makes the tire waste soft and not easily decomposed and recovered. However, the manufacturer cannot directly recycle and reuse the tires, and the recycling of the tires is limited to the decomposition of the waste tires. The wastes cut during the tire manufacturing process can only be discarded, resulting in waste of raw materials and environmental damage. The technical problem to be solved by the present invention is ascertained.

The invention relates to a method for decomposing from a tire scrap, which comprises the following steps: large breaking treatment, small breaking treatment, (coarse) degumming treatment, (fine) degumming treatment, wherein the large breaking treatment is performed after cutting the tire in the tire manufacturing process. Using the large crusher for the first decomposition, the scraps are formed into larger rubber fragments; after the small breaking treatment, the rubber scraps processed by the large crusher are secondly decomposed by the small crusher to make the rubber fragments Forming a relatively small piece of rubber; (coarse) degumming treatment, which is followed by large and small broken rubber pieces after being treated with steel wire due to the tire process, then the rubber pieces are separated from the steel wire by a degumming machine At least 80% of the rubber fragments are effectively separated from the steel wire, and then magnetically screened by the magnetic separator to concentrate the steel wire and the rubber fragments which are also doped with the steel wire, and the rubber material after the smooth degumming is additionally affected. Conveyor belt transport recycler; (fine) degumming treatment, which is also coated with rubber scraps after being screened by magnetic separator, and then degummed by degumming machine, so that the steel wire can be effectively broken From decomposition, and magnetic attraction by the magnetic separator, the rubber crumb thereby allowing the wire can be completely decomposed, and the compound formed is transported recycler; decomposition by the above method, Bineng Effectively decompose and recycle tire scraps.

The invention provides a method for decomposing a tire waste material, which utilizes a large and small crusher to effectively crush the waste material into relatively fine rubber fragments, and then cooperates with the degumming machine to disintegrate the steel wire doped in the rubber fragment. In addition, with the magnetic separator, the decomposed steel wire is adsorbed and screened, so that the cut material in the tire manufacturing process can be decomposed into a rubber material for the recycler to recycle.
