Rubber powder is the intermediate product that regenerating waste or used rubber utilizes, and it is a valuable source of producing reclaimed rubber.Therefore its quality is determining the quality of reclaimed rubber.

At present the main dynamic vulcanization process that adopts is handled in the desulfurization of rubber powder, be that the rubber powder and a certain proportion of regenerator (being activator and tenderizer) that need desulfurization to handle are put into the pressurized vessel of sealing, pressurize, heat, add water and carry out the desulfurization processing, there is following defective:

1, pressure is big, and the operating pressure during desulfurization is 2.2~4.0MPa, and dynamically digester need adopt II class pressurized vessel, and life-time service or improper use, can cause potential safety hazards such as tank skin attenuation, even cause equipment and fatal accident.

2, Jia Shui and exhaust gas emission is arranged, for preventing under the hot conditions, rubber powder is heated inequality and charing will add a certain amount of water to form steam or directly feed water vapour as heat-transfer medium when desulfurization, yet water vapor with; Produce complicated reaction with the tenderizer that adds, the waste gas that causes difficulty to be smelt produces, and causes serious environmental to pollute.Though existing processing the, contaminated solution problem fundamentally still at present.

3, production process is that the gap produces, and hand-fed, can not continuous production, and productivity is low, labour intensity height, the effort of taking a lot of work.

4, power consumption is high, owing to be that the gap produces, and all in vain the discharging wastes of high pressure, steam, and production cost height.

5, the quality instability is wayward; Owing to be that the gap produces, quality fluctuation between each batch is big, wayward, and owing to be under the working condition of high pressure, high temperature, high humidity, to carry out complicated reaction, the quality of each batch only just can be known the quality of product behind release, discharge of steam, so the also bad control of the quality of each batch.

6, the rubber powder after handling must carry out just being used for after the processed production of reclaimed rubber products; And the complex process of processed needs a whole set of equipment, and investment is big, energy consumption height, cost height.

Three, summary of the invention

We have developed a kind of rubber powder plasticizing process recently, be waste old to be crushed to 10~40 purpose rubber powders add a certain proportion of activator and tenderizer, behind the uniform mixing, be heated to 180~320 ℃, be incubated 8~15 minutes, carry out the desulfurization plasticizing, promptly get the plasticizing rubber powder after plastifying after the cooling.This technology has can realize automatic continuous production, and no pressure, non-exhaust emission, pollution-free are safe and reliable, steady quality is easy to control, and the plasticizing rubber powder after the processing need not to dewater and both can be directly used in the production of rubber item, and is energy-saving and cost-reducing, less investment, characteristics such as cost is low.

The purpose of this utility model is to provide a kind of automatic continuous producing device for this rubber powder plasticizing process.This device can satisfy the needs of rubber powder desulfurization plastics processing, can realize automatic continuous production, and is simple in structure, easy to operate, steady quality, and easy to control, cost is low.
