Abstract

The machine mainly comprises a prime moter, an abrasive machine and a rubber-powder collecting device. The prime moter is driven by the right motor and transmitted through the V-belt or a speed-reducer to make the waste tyre clockwise quickly rotate. The abrasive machine is driven by the left-motor and transmitted throug the V-belt or a speed reducer to make the two abrasive-wheel shafts eg. a set of four abrasive-wheel pieces quickly rotate and contact with the said tyre to make fine regerated rubber-powder. The grain size of said rubber-powder can be up to above 100-200 mesh.

Description

The production method of micro-fine regnerated rubber powder and equipment

The invention belongs to the regeneration techniques field of rubber for tire, system does not relate to the production and the equipment of fine raw rubber powder.

At present, producing regnerated rubber powder at home is to adopt the edging platen press, block rubber is used after the edging pressure, cross sieve classification with metallic screen, the rubber powder of not crossing sieve aperture pushes again, sieves, because rubber is plastic material, diminish during extruding, become big after the extruding again, even if repeat repeatedly, rubber powder granule can only reach 28 order to 40 orders.Can only be used for unessential product and be lower than 80 purpose rubber powders; For solving this difficult problem, State Scientific and Technological Commission will list current China brainstorm project in the equipment that can produce 80 purpose rubber powders.

The method of producing the raw rubber powder abroad is to adopt subcooled method, rubber for tire is refrigerated to below-200 ℃ becomes rigid vitreous humour, and then smashes or powder with crushing mill, and this equipment needs import and costs an arm and a leg, freezing environment is difficult to keep, and causes the production cost height.For addressing the aforementioned drawbacks, so propose the present invention.

The object of the invention, for handling junked tire, producing micro glue powder, the new tire and improve performance, save and to open right rubber, reduce import and a kind of new method and the equipment that propose of regenerating.

Production method of the present invention is: junked tire is cleaned up and inflates 2 to 3 pressure, rising machine with transportation is contained in tire on prime mover, moving more right motor, power change two junked tires per minute rotation along clockwise direction 2 to 50 through the right decelerator of V belt, final drive shaft; Then operate the transmission of manual control lever shaft, hinge wheel, chain, minor sprocket, leading screw, screw, make dolly move closer to two tires; Start left motor,, make 4 wheel sheet groups be rotated in a clockwise direction 500 to 2500 rev/mins, when emery wheel contact tire, then because of direction causes high-speed grinding mutually on the contrary, to produce ultra-fine rubber powder and to fall into blanking port through V belt or decelerator, grinding wheel spindle; The axial flow blower of starting rubber powder gathering-device makes the blanking port place produce negative pressure; Rubber powder is along with the absorption of distinguished and admirable sand removing hole sediment outflow through the material pipe, electric heater heating (110 ℃), static anode network and static cathode screen high-tension electricity (1.5 volts to 30,000 volts), arrive pure rubber powder bagging-off spout at last, when the fiber of cathode screen acquires a certain degree, then instantaneous shutdown, the negative electrode expanded metals has a power failure, and fiber is discharged through outlet; When grinding temperature is high, open water droplets device cooling grinding wheel group; When reaching the regulation fineness through being up to the standards before the rubber powder pack (100 order to 2000 order), warehouse-in is sealed in pack at last up for safekeeping.

Production equipment that the present invention adopts: mainly comprise prime mover, abrasive machine and rubber powder gathering-device, establish right motor, V belt decelerator in prime mover, power is passed to final drive shaft, junked tire is rotated at a high speed along ground pin direction reach 2 to 50 rev/mins; Establish left motor, V belt or decelerator in the abrasive machine, power is passed to two grinding wheel spindles and four grinding wheel groups, and can rotate its angular speed along clockwise direction at a high speed and reach 500-2500 rev/mins, above-mentioned parts is fixed on the movable trolleys, the four wheels of dolly is positioned on the light rail, the dolly bottom is provided with leading screw, screw, when the slewing maneuver dish, can make the emery wheel on the dolly touch tire by sprocket wheel, chain, leading screw, screw.The rubber powder of grinding enters the rubber powder gathering-device, and through axial flow blower suction streams feeding pipe, through sediment outflow, electrical heating, the absorption of high-pressure electrostatic net, last rubber powder flows to bagging-off spout, and useless fiber is discharged through floss hole, and the water droplets device can cool off emery wheel.

Advantage of the present invention:

A, handle junked tire, reduced pollution, the finance department also rewards the processing ground rubber in the mode of collecting taxes not.

The micro glue powder granularity of b, the production of employing this programme can reach 100 orders, even reaches 200 orders, in the epoch of the long-term dependence on import micro glue powder that is through with, can be country and has saved a large amount of foreign exchanges.

C, utilize ground rubber not only can save natural rubber, and send the life-span that also increases tire.
