Extruder comprises following equipment: power section, transmission system, speed change system, extruder screw, extruding machine barrel, extruder charging aperture, heating system, cooling system, control system, extruder filter; Wherein power section links to each other with transmission system, speed change system is between transmission system and extruder, extruder screw and heating system are arranged in the extruding machine barrel, the extruder charging is positioned at the upper left side of extruser, control system is positioned at the extruser top, and the extruder filter is positioned at outlet of extruder; Wherein, the design feature of extruder: (1) feed inlet end belongs to the extruder 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 extruder 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) extruder discharge gate place is provided with the quick net exchanging filter.The structure of extruder sees Fig. 3 for details.
Method of the present utility model is that in the following order step is carried out:
Waste old is ground into the particle of 1～10mm, join in the micro-wave oven through screening, magnetic separation, feeding device, utilize microwave energy that rubber grain is carried out desulfurization, directly enter the extruder charging aperture by the micro-wave oven discharging opening, after plastifying, filter by extruder, produce and to utilize rubber raw materials.
Used other the equipment of the utility model:
A rubber crusher, a b material screening machine, c magnetic force sorting machine, d feeder, e desulphurization microwave stove, f extruder and filter, g packaging facilities.In the above equipment, micro-wave oven and extruder belong to the present invention and design creation equipment.
The utility model compared with prior art has following advantage:
1, equipment volume is little, output is big, can produce continuously;
2, the particle of 1～10mm can directly be processed;
3, energy consumption is low, and power 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 mechanization of dependable performance, fault rate, automaticity height;
7, pollution-free, the whole process of production closed conveying, no pernicious gas is revealed, and noise is low;
