Description
The present invention relates to the polymeric material process field, particularly, relate to the equipment that produces powder from the waste product regeneration of high-strength polymer material.This equipment can be to use in the waste disposal of product of base substance at polymer with rubber, these products contain metal wire, wire netting and high strength fibre, fabric etc., for example, when recycling automobile and aero tyre, metal is separated from rubber with synthetic thread.
Known have a kind of equipment usable polymers manufacture of materials powder, particularly from the waste product of rubber product, produce powder, this equipment comprises a cylinder, there is the continuous coaxial empty chamber that is used for pushing with grinding cylinder inside, a charger, a heater and a grinding attachment, comprise the first and second grinding parts, these two grinding parts can relatively rotate, a gap (Japan Patent 05337943 that utilizes the frictional force grinding is arranged in the middle of them, B 29 B 17/00 class, priority on June 11st, 1992).
Yet this known device is not outstanding aspect productivity ratio, owing to use friction surface to carry out grinding, thereby greatly reduce its productivity ratio.In fact this equipment can not be handled the polymer of being strengthened by metal wire and high strength fibre, because sheet metal is plugged slots, i.e. and grinding gap.In a nearlyer step,, make that this equipment and even whole technique flow process are more complicated owing to must use microwave device that the rubber waste product is heated.
A kind of known equipment of producing powder from polymer, this equipment comprises a cylinder block with reinforced and discharging opening.A compression screw rod is housed in this cylinder body compressional zone, helicla flute is arranged on the screw surface.Profile is revolving body and rotary rotor, and inboard wall of cylinder block forms an annular gap relatively, and gap and compression screw coaxial place in the grinding area.Be processed with a looping pit on the surface of compression screw rod, there is 1～8 millimeter the degree of depth at the shallow place in hole, and its end and rotor adjoin and/or be positioned on the rotor surface and end and compression screw rod adjoin.In grinding area, this equipment also is provided with rotor and/or cylinder body cooling device (Russ P 205701, B 29 B17/00 classes in 7, on February of priority-1994, were announced on March 27th, 1996).
