Clearer production process and preparation system for junked tire

Abstract

The invention discloses a clearer production process and a preparation system for junked tire. The process mainly comprises the following steps: (1) collecting junked tires as raw materials; (2) weighing the raw materials, and automatically recording weight and dimension; (3) cleaning the raw materials by treating each tire by a low-pressure multi-direction water curtain; (4) cutting raw material: after treatment by the low-pressure multi-direction water curtain, selecting a processing efficiency mode, aligning with a set center line and sending the tires one by one into a semi-closed three unit cutting and processing intelligent system; and after the intelligent positioning, cutting each tire into three independent units through a PLC model; (5) pulverizing the raw materials; and (6) treating semi-finished products. According to the invention, each junked tire is directly cut into a ring tire and two sidewalls to form three units. The process has no requirement on tires, simplifies the key process steps and reduces machines; the process is different from prior art, in which a cover tire surface is first peeled off, and then an inner tube is treated; therefore, the process provided by the invention greatly improves the processing capacity and efficiency.

Description

technical field [0001] The invention relates to the field of waste tire treatment, in particular to a clean production process of waste tires and a preparation system thereof. Background technique [0002] Due to the development of the automobile and motorcycle industry driven by economic prosperity, the number of motor vehicles in the world has increased rapidly, and about two to three billion waste tires are produced every year, and my country also produces hundreds of millions of waste tires every year. Scrap tires are mainly composed of vulcanized rubber, which is very stable and can last for more than 100 years in the natural environment without decay. In addition, waste tires have good elasticity and toughness, and cannot be compacted by mechanical force. Therefore, they occupy a large amount of space in traditional landfills and shorten the service life of landfills, so they are not suitable for burial with general waste. If it is piled up randomly and encounters rai...

Problems solved by technology

[0010] The crushed waste tire rubber blocks can be used as auxiliary fuel, or obtain government subsidies for waste disposal, with low economic value

The crushed fine rubber powder can be recycled and sold, but because additional equipment must be purchased for screening operations, the cost will naturally increase

[0011] In addition, in the traditional processing technology, after the long-term operation of the primary and secondary crushers, the potential thermal effect problem plagues the decomposition process, resulting in large consumption of crushing tools and poor economic benefits

Furthermore, the primary and secondary crushers have input caliber restrictions and cannot directly process tires with a diameter exceeding 24 inches

When running into this situation, the steel wire of the bead of the waste tire must be pulled out first, and then cut into smaller pieces of waste tire and put into the coarse shredder for processing. However, the steel wire contained in the waste tire above 24 inches is relatively large. Many and thick, it is easy to cause rapid loss of the reamer of the primary crusher and secondary crusher

Therefore, it is not economical to dispose of waste tires larger than 24 inches, and they are often not included in the disposal items of waste disposal sites.

[0012] In addition, tire blowouts for heavy trucks or waste tires with steel wire layers exposed due to severe tread wear caused by excessive use of tires are common problems, and they will inevitably occur in large numbers

At the same time, during the implementation process, it was also confirmed that the previous manufacturing process was limited by the problems of tire selection caused by defective tires, punctured tires, ruptured tires, and overused waste tires, which greatly limited the processing capacity and efficiency of the manufacturing process.

The crux of this problem is that the previous method of stripping the outer tread first, and then processing the inner tread will cause the complete mechanical behavior of the waste tire to be destroyed, the tire rigidity will be greatly reduced, and the deformation will increase, so that the structural deformation under the action of external force cannot allow The active force effectively exerts the due work effect, that is, produces virtual work, wastes electric energy in vain, and leads to the so-called tire picking phenomenon, so that subsequent processing operations cannot be carried out effectively. In order to solve this problem, the present invention is based on Significant changes have been made in the practice and processing organization to meet the needs of commercial operations, especially for the needs of tire manufacturers in the processing of defective tires that will inevitably occur during the production process
