Problems solved by technology

[0002] The existing production process of radial tires has the following shortcomings and deficiencies: 1. Complex structure, long production line, high equipment failure rate
The existing rubber production line for radial tires includes two crushers, one extrusion machine, ten crepe machines, three granulators, two rubber pumps, five floating washing tanks, one drying system, Two hydraulic balers and a metal detector constitute a relatively complex production line. When all production equipment is turned on at the same time, the failure rate increases accordingly.
2. High production cost and low work efficiency
When the existing production line is started, a total of 8 people are required to be deployed from single-stage crushing to rubber loading. The labor cost is relatively high. Due to the large number of equipment and complex configuration, the maintenance and repair costs are high. If any equipment in the production line Failure will lead to production stoppage, and the overall failure rate of equipment will increase and work efficiency will be reduced
3. High energy consumption
The sum of the main equipment power of the existing production line is 1826KW, and at least 1826 kwh of electricity must be consumed per hour during production, and some crepe machines are in an idling state during equipment operation, which does not have the effect of removing impurities, and some crepe

Embodiment 1

[0032] Divide the recycled rubber raw materials into two grades according to the evaluation results of "Dehong Gaoshen Rubber Industry Development Co., Ltd. Raw Material Control Quality Requirements", remove the sundries on the surface of the recycled rubber raw materials, and break them into rubber blocks of 44cm×13cm×16cm. The graded rubber raw materials after impurity removal are mixed in a weight ratio of 1:3 and sent to the crushing process. The mixed rubber material is crushed in the first stage to make a rubber block of 15cm×13cm×6cm, and the rubber block is stirred and mixed evenly in the floating washing water, and the floating washing time is 12 minutes; then the mixed rubber material is crushed in the second stage to make 7cm×7cm×4cm rubber block, and make the rubber block mix evenly in the floating washing water. The floating washing time is 13min. Further, the mixed rubber material is first squeezed by double rollers, floated and washed, and then squeezed by single...

[0036] The recycled rubber raw materials are divided into two grades according to the evaluation results of "Dehong Gaoshen Rubber Industry Development Co., Ltd. Raw Material Control Quality Requirements", and the sundries on the surface of the recycled rubber raw materials are removed, and they are broken into rubber blocks of 40cm×10cm×8cm. The graded rubber raw materials after impurity removal are mixed in a weight ratio of 1:1 and sent to the crushing process. The mixed rubber material is crushed in the first stage to make a rubber block of 10cm×10cm×4cm, and the rubber block is stirred and mixed evenly in the floating washing water, and the floating washing time is 11 minutes; then the mixed rubber material is crushed in the second stage to make 5cm×5cm×2cm rubber block, and make the rubber block mix evenly in the floating washing water. The floating washing time is 12min. Further, the mixed rubber material is first squeezed by double rollers, floated and washed, and then ...

Embodiment 3

[0040] Divide the recycled rubber raw materials into two grades according to the evaluation results of "Dehong Gaoshen Rubber Industry Development Co., Ltd. Raw Material Control Quality Requirements", remove the sundries on the surface of the recycled rubber raw materials, and break them into rubber blocks of 50cm×15cm×20cm respectively. The graded rubber raw materials after impurity removal are mixed in a weight ratio of 1:2 and sent to the crushing process. The mixed rubber material is crushed in the first stage to make a rubber block of 25cm×15cm×10cm, and the rubber block is stirred and mixed evenly in the floating washing water, and the floating washing time is 10 minutes; then the mixed rubber material is crushed in the second stage to make 10cm×10cm×5cm rubber block, and make the rubber block mix evenly in the floating washing water. The floating washing time is 11min. Further, the mixed rubber material is first squeezed by double rollers, floated and stirred, and then s...

Abstract

The invention discloses a processing method of rubber special for radial tires. The method includes the steps that recycled raw rubber is divided into two grades according to assessment results of quality detection standards of enterprises and is crushed into rubber blocks with the sizes ranging from 40cm*10cm*8cm to 50cm*15cm*20cm, and the purified graded raw rubber is mixed according to the weight ratio of 1-3 to 1-3; the mixed rubber sequentially undergoes primary crushing, floatation stirring, secondary crushing and floatation stirring with the total floatation time greater than or equal to 20 minutes, then undergoes two-stage extrusion flotation with the floatation time greater than or equal to 12 minutes and finally forms micelles; the rubber undergoes crumpling treatment from the stage one to the stage three and undergoes primary granulating treatment, and manufactured rubber particles are made into rubber sheets with the thickness being 6-12 mm through crumpling treatment from the stage four to the stage six and then are made into rubber particles with the diameters being 6-12mm through secondary granulating treatment; and the rubber particles undergo rubber pumping and vibrating treatment, then are dried at 82-106 DEG C according to the 4-6 t/h standard of the rubber and finally are cooled to indoor temperature. According to the method, the purification rate of equipment is increased, the phenomenon that the structure of the rubber is damaged due to excessive processing is avoided, the equipment layout of a production line is simplified, the total failure rate is lowered, the amount of rubber scraps is reduced, and the production efficiency is improved.
