Abstract

The present invention relates to a treatment method for regenerating waste and used rubber scraps and its equipment. The waste rubber scraps, polyalkylphenoldisulfide and softening agent pine tar are placed in a dynamic heating devulcanizing pan to implement direct desulfurization-regeneration method. Said dynamic heating devulcanizing pan is a metal cylindrical pan composed of driving gear portion, pan body, baffle plate of internal wall of the pan and temp.-measuring device. Said invention is simple in equipment, rational in technological process, low in cost, and only has need of devulcanizing pan and mixing machine.

Description

Waste old comer blocks clout direct desulfurization method of reproduction and device thereof

The present invention relates to a kind of organic high molecular compound, particularly a kind of waste old comer blocks clout manipulation of regeneration method and device thereof.

At present, China produces reclaimed rubber two kinds of oil process and water/oil methods, uses the machinery mill to grind to its cutting (powder process) and finishes.Adopt separator to separate to the natural and synthon in the sizing material, desulfurization is finished for steam with boiler.Its problems referred to above are:

1, must possess primary crusher, fine crusher, spiral conveyer, vibratory screening apparatus, winnowing machine, magnetic separator, steam boiler, digester, mix equipment such as oily machine, stirred pot, rubber mixing machine and oven dry extruding, complex process, investment is big, and a whole set of processing unit need be invested more than 100 ten thousand yuan;

2, the cycle of operation long, labour intensity is big, power consumption is big;

3, technical indicator is the end of than, the grinding particle size inequality;

4, contaminate environment and being detrimental to health.

No. 921062109 contents of the patent of announcing according to the Chinese patent communique are: " cutting sizing material, heating, the softening regenerator of adding, discharging, go up the rubber mixing machine slice of plasticating." waste old tailing direct desulfurization method and device thereof.Be to yield poorly with the problem that this method produced, effect is not good enough.

The present invention has developed a kind of new waste old tailing direct desulfurization method and used device thereof for overcoming the problems referred to above.This method has:

1, the sizing material of Sheng Chenging can be as industrial raw material;

2, present device is simple, and technology is reasonable, and cost is low, only needs digester and rubber mixing machine, and regenerated sizing material technical indicator satisfies industrial requirements;

3, the present invention is easy to operate, reduces overweight labour intensity;

4, the present invention saves the energy, instant effect, and profit is big.

The purpose of this invention is to provide a kind of waste old comer blocks clout direct desulfurization method of reproduction and used device thereof of utilizing.

The present invention is achieved in that waste old comer blocks clout is cut, washes, and places in the dynamic heat digester, adds tenderizer, activator.This jar is a round metal cartridge type structure, and mainly by transmitting gear part, tank body, jar inner wall baffle-plate, turnover bin gate and blast inlet, exhaust smoke outlet and carriage, support roller, temperature measuring equipment constitutes.Jar is rotated heating simultaneously, and through regular hour and temperature, sizing material changes original physical condition, crosslink portion fracture, swelling, softening, take out sizing material and place and stir cooling in the material container, treat that the sizing material temperature is reduced to room temperature after, last rubber mixing machine is plasticated, thin-pass, slice.

Processing method of the present invention and device:

One, processing method:

1, sizing material is handled

Waste rubber is cut into 10 * 10cm left and right sides flap, and the waste rubber product of band fiber should fall its fiber treatment, as autotyre casing etc.Sizing material washing back after the cutting is stand-by.

2, desulfurization regeneration

With sizing material 98-95%, polyalkylbenzene phenol disulphide (activator 420) 2.5-1%, tenderizer Stockholm tar 2.5-1%, weight is all by 100%, place in the dynamic heat digester, tank body is heated and makes tank body rotation, because a jar inwall has baffle plate, sizing material is in vacant state all the time during the tank body rotation.10-30 rev/mins of its jar revolutions, about 130 ℃-280 ℃ of temperature when its a kind of sizing material is risen to certain temperature, stop heating, be incubateds 5-10 minutes, stop jar, sizing material goes out jar." elasticity " is softened, activates and lost to sizing material being changed in jar, at preheating, crosslink portion fracture, swelling.Go out behind the jar its sizing material placed to add a cover in the container to stir and make its cooling, treat that the sizing material temperature drops to room temperature after, can place on the rubber mixing machine plasticate, thin-pass, slice.

Two, device

Device of the present invention is a round metal cartridge type jar, and by transmitting gear part, tank body, jar inner wall baffle-plate, turnover bin gate and air intake exhaust smoke outlet and carriage support roller, temperature measuring equipment constitutes.

The unusual effect that the present invention had is:

1, technology of the present invention is simple, and is easy to operate, owing to adopt waste old comer blocks and goods through simply cutting as raw material, save flouring technology, so cost is low, instant effect, and profit significantly improves.

2, eliminated heavy expensive a complete set of processing unit, the reclaimed rubber of being through with over must be processed into the backward technology of rubber powder with putting in order glue limit piece.

3, equipment is simple, invests for a short time, only needs bale splitter, dynamic heat digester and rubber mixing machine, and power consumption is few, reduces labour intensity and pollution.

4, Economic and Efficiency Analysis: China scrap rubber material source is sufficient, and annual generation reaches more than 50 ten thousand tons approximately, and it is low to sell the pin cost, and fabulous prospect is arranged.As Application and Development, will be country and society's creation great riches.

Embodiment 1:
