(1), by the junked tire of recovery through the broken broken apart rubber grain for obtaining 1-8mm of train line of full-automation, pass through Feed bin wind delivers to feed plasticizing apparatus charging aperture, and rubber grain is delivered in feed plasticizing apparatus by agitating auger, and is passed through Single screw rod is conveyed and electromagnetic heater realizes that first-level transport is plastified, and feeding speed is 100-400kg/h, and agitating auger rotating speed is 100-200r/min, single screw rod rotating speed is 200-400r/min, and Electromagnetic Heating temperature is 50-100 DEG C, first-level transport plastics processing Time is 3-5min;
(2), through step(1)First-level transport plastifying material restores anti-by being fed plasticizing apparatus discharging opening into millstone type scrap rubber Device charging aperture is answered, is then entered between fixed millstone and movable grinding disc through material distributing cone, movable grinding disc is subject to millstone type scrap rubber to restore reaction Under the drive of device motor rotate and material is carried out screw-type extrusion, ring shearing, stretching action, material is worn into powdery While also achieve the disconnected sulfur regeneration of two grades of greens, the control of movable grinding disc rotating speed is cooled down by cooler pan and tied in 300-400r/min By temperature control at 150-190 DEG C, the material of regeneration is delivered to millstone type and is given up through the rotation of scraper blade in gap between structure and mill Rubber restores reactor discharging opening;
(3), through step(2)The regeneration feed of discharge enters cyclone separator by the passage closed, and regenerative process is produced Waste gas delivers to exhaust treatment system from upper end exhaust outlet, and regeneration feed is then discharged by cyclone separator lower end discharging opening;
(4), cyclone separator discharging opening discharge reclaimed rubber by closed channel enter cool down mixing and filtrating device charging aperture, It is cooled in conveying and mixing process after device is cooled to 50-60 DEG C by twin-screw, the motive force by twin-screw makes Cooling reclaimed rubber crude product after the impurity such as filter removing steel wire and the particulate matter not regenerated completely by obtaining required regeneration Rubber semi-finished product, twin-screw rotating speed is controlled in 130-270r/min;
(5), reclaimed rubber semi-finished product after filtering by granulation packing device treatment, realize that automatic granulating is packaged to be regeneration rubber Glue finished product.
9. scrap rubber green according to claim 8 restores regeneration integrated production method, it is characterised in that:The rubber The preferred 2-4mm of glue particle size, it is 75 DEG C that the Electromagnetic Heating temperature is optimal, and it is 200kg/h that the feeding speed is optimal, described It is 146r/min that agitating auger rotating speed is optimal, and it is 320r/min that the single screw rod rotating speed is optimal, and the movable grinding disc rotating speed is optimal to be 365r/min, it is 210 r/min that the twin-screw rotating speed is optimal.
