Purpose of the present invention can realize by following measure: this method is carried out as follows:
Waste old is ground into the particle of 1～10mm, join in the microwave oven through screening, magnetic separation, feeding device, utilize micro-wave energy that rubber grain is carried out desulfurization, directly enter the forcing machine opening for feed by the microwave oven discharge port, after plastifying, filter by forcing machine, produce and to utilize rubber raw materials.
Device of the present invention is the equipment that comprises in the following order: pulverizer, sifting machine, magnetic separator, feeding machine, microwave oven, forcing machine, filtration unit and packing apparatus, see Fig. 1.
The design feature of microwave oven: (1) vertical type; (2) according to the assimilation effect difference of different rubber, microwave oven is divided into several zones to microwave energy; (3) every district microwave energy can be regulated and control; (4) temperature in every district can be measured, and according to the difference of rubber clone, each distinguishes Controllable Temperature built in 160～350 degrees centigrade; (5) discharge port of microwave oven is directly connected to the forcing machine opening for feed.Microwave oven structure sees Fig. 2 for details.
Forcing machine comprises following equipment: power section, transmission system, speed change system, extruder screw, extruding machine barrel, forcing machine opening for feed, heating system, cooling system, Controlling System and forcing machine filtration unit; Wherein power section links to each other with transmission system, speed change system is between transmission system and forcing machine, extruder screw and heating system are arranged in the extruding machine barrel, the forcing machine charging is positioned at the upper left side of extruser, Controlling System is positioned at the extruser top, and the forcing machine filtration unit is positioned at outlet of extruder; Wherein, the design feature of forcing machine: (1) feed inlet end belongs to the forcing machine heating system and partly begins the position, belongs to high temperature section, accounts for 2/3rds of extruding machine barrel length overall, and temperature is controlled at 160～350 degrees centigrade; (2) the forcing machine cooling system partly belongs to low-temperature zone, accounts for 1/3rd of extruding machine barrel length overall, and temperature is controlled at 160～80 degrees centigrade; (3) forcing machine discharge gate place is provided with the quick net exchanging filtration unit.The structure of forcing machine sees Fig. 3 for details.
Used other the equipment of the present invention:
A rubber crusher, a b material sifting machine, c magnetic force sorting machine, d feeder, e desulphurization microwave stove, f forcing machine and filtration unit, g packaging facilities.In the above equipment, microwave oven and forcing machine belong to the present invention and design creation equipment.
The present invention compared with prior art has following advantage:
But 1, little, the big continuous production of output of equipment volume;
2, the particle of 1～10mm can directly be processed;
3, energy consumption is low, and current consumption per ton is about 300 degree;
4, low cost of manufacture need not be added any auxiliary agent in sweetening process;
5, efficient height, labour intensity are low;
6, low, the mechanize of dependable performance, failure rate, level of automation height;
7, pollution-free, the whole process of production custody transfer, no obnoxious flavour is revealed, and noise is low;
8, sweetening effectiveness is good, and quality is even, but the utility value height.
