The objective of the invention is to realize by the following technical solutions:

A kind of waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing method, it is characterized in that: start alternating current machine and drive the agitator rotation, successively with waste vulcanized rubber powder, regenerator is added to and is provided with outer cooling chuck, in the digester of vertical paddle turbine agitator, stirring velocity is 350r/min, stirred 20 minutes, when temperature reaches 70~75 ℃, material in the digester cools off the discharge opening of the worm conveyor of chuck outside having, put to container or on the ground quiet put 2~5 days after, again this material is added in the digester and stirred 40 minutes, after being warming up to 75 ± 4 ℃, in described its cooling jacket, be connected with in the worm conveyor of water coolant and cool, obtain plastifying rubber powder and deliver to kneading in the mill to below 50 ℃.

Above-mentioned waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing method, vertical paddle turbine agitator in its described digester is a three-decker, be to be 45 ° straight tiltedly paddle by its horizontal sextant angle that turns forward that is equipped with successively from bottom to top on the main shaft, have down, in, go up the turbine of three-decker, its horizontal sextant angle that recedes is that 10 ° fan blade constitutes.

Above-mentioned waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing method is established condenser on its described digester upper cover.

Above-mentioned waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing method, it is described to have down, in, go up the turbine of three-decker, its lower floor be by be welded with on the axle sleeve three each other the straight horizontal paddle of hexagonal angle constitute, its described three straight horizontal paddles turn forward, and its level inclination is 15 °; Its middle layer is by the outer end that is welded on three straight horizontal paddles on the axle sleeve in described turbine lower floor, is welded with three vertical paddles and constitutes; Its middle layer is to be welded on the axle sleeve three hexagonal angle straight horizontal paddle outer ends each other by the lower floor at described turbine, being welded with three vertical paddles that turn forward constitutes, be welded with annulus on these three vertical paddles, the inboard tangent line angle with annulus of described vertical paddle is 15 °; Described annulus upper surface slopes inwardly, and its horizontal sextant angle is 15 °; Its upper strata be welded with by described annulus and this annulus outside three each other the straight horizontal paddle of hexagonal angle constitute, described three straight horizontal paddles turn forward, its horizontal sextant angle is 15 °.

A kind of waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing device is characterized in that: this device mainly by alternating current machine, vertical paddle turbine agitator is housed and cool off the digester of chuck outward, the worm conveyor that has an outer cooling chuck is formed; Described alternating current machine links to each other with the power wheel that is in digester bottom main shaft by belt; Link to each other with pipeline between digester discharge port and the described worm conveyor; Worm conveyor links to each other with the direct connection speed reduction unit; Be provided with discharge opening near on the worm conveyor of direct connection speed reduction unit one side.

Above-mentioned a kind of waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing device, its described vertical paddle turbine agitator is a three-decker, is to be that straight tiltedly paddle, the turbine with three-decker, its horizontal sextant angle that recedes of 45 ° is that 10 ° fan blade constitutes by its horizontal sextant angle that turns forward that is provided with successively from bottom to top on the main shaft.

Above-mentioned a kind of waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing device, its described digester upper cover is provided with condenser, and recovered steam water of condensation circulation is in order to the activator in the preparation regenerator, environment polluted preventing.

Above-mentioned a kind of waste or used vulcanized rubber atmospheric cryochemistry ageing effect desulfurizing device, it is described to have down, in, go up the turbine of three-decker, its lower floor be by be welded with on the axle sleeve three each other the straight horizontal paddle of hexagonal angle constitute; These three straight horizontal paddles turn forward, and its level inclination is 15 °; Its middle layer is to be welded on the axle sleeve three hexagonal angle straight horizontal paddle outer ends each other by the lower floor at described turbine, being welded with three vertical paddles that turn forward constitutes, be welded with annulus on these three vertical paddles, the inboard tangent line angle with annulus of described vertical paddle is 15 °; Described annulus upper surface slopes inwardly, and its horizontal sextant angle is 15 °; Its upper strata be welded with by described annulus and this annulus outside three each other the straight horizontal paddle of hexagonal angle constitute, described three straight horizontal paddles turn forward, its horizontal sextant angle is 15 °.

Above-described three its horizontal sextant angles that turn forward that are welded on the annulus outside are 15 ° of straight horizontal paddles, can be in the optional position in the annulus outside, need only isogonism each other.

Start alternating current machine and drive vertical paddle turbine agitator rotation, then waste vulcanized rubber powder and regenerator are added in the digester successively, rubber powder and regenerator are stirred rapidly.The straight horizontal paddle of straight tiltedly paddle, formation turbine promotes rubber powder and regenerator moves in a circle, under the tank skin constraint, rotate around main shaft, and vertical paddle on the turbine and annulus can destroy the laminar flow regime of rubber powder, rubber powder is being disturbed when main shaft rotates, has aggravated the friction between friction, rubber powder and the desulfurization tank skin between friction, rubber powder and the described agitator of rubber powder inside.In addition, be installed in the fan blade on described agitator top, recede, and the straight horizontal paddle turns forward, and the two vergence direction is opposite, and rubber powder is concentrated to agitator, the diffusion that rubber powder is made progress suffers restraints, play the baffling effect, making the rubber powder that suspend concentrate on described agitator around, violent friction is risen the temperature of rubber powder.The rubber powder of a lot number just can be raised to 70~75 ℃ in about 20 minutes in stirring, thereby rubber powder and regenerator are stirred.After the ageing treatment, carry out about 40 minutes stirring for the second time, temperature is raised to 75 ± 4 ℃, finishes the vulcanized rubber powder desulfurization regeneration.

Stirring is warmed up to 70~75 ℃ rubber powder and places and to carry out ageing treatment in 2~5 days, and tenderizer, activator are continued to rubber powder internal penetration, infiltration, makes rubber powder softening and mould and separate, and helps the low-temp desulfurization second time.Can reach the purpose that reduces desulfurization temperature by ageing treatment.

Desulfurization for the second time need feed intake at normal temperatures, because temperature can violently rise after the digester temperature feeds intake than relative superiority or inferiority, do not guarantee the needed time of desulphurization reaction, and feed intake at normal temperatures, just can feed intake about the 40 minutes time of stirring, temperature is raised to 75 ± 4 ℃.For this reason, on digester, be provided with external cooling water jecket.After the first lot number desulfurization finished, logical water coolant lowered the temperature of digester tank body, and lot number is fed intake at normal temperatures.

In order to realize that desulfurization works continuously, two digesters that all have cooling jacket can be set.Finish the rubber powder after the desulfurization, be put into worm conveyor Nei Shibian and carry the limit cooling, temperature of charge has dropped to about 50 ℃ when discharging worm conveyor, and rubber powder has not had flue gas, can not pollute environment.
