Description

Two continuously mixing feeding units of a kind of automobile-used waste and old GMT material recovery granulation
Technical field
The utility model relates to a kind of automobile-used waste and scrap retracting device, specifically, is two continuously mixing feeding units of a kind of automobile-used waste and old GMT material recovery granulation.
Background technology
Along with automobile is to lightweight, energy-saving and emission-reduction, Comfortable attractive future development, plastics grow with each passing day at the consumption of automotive field, and its consumption and application technology thereof have often become the important indicator weighing a national auto industry level.But unexpectedly, just because of the extensive application of these plastics, cause it after use or consumption, become the durable rubbish be stale-proof, accumulate over a long period, will increase the weight of " white pollution " problem in the whole world further, the quality of life directly affecting people even threatens the physical and mental health of people.Thus recycling process is carried out to waste or used plastics, have important meaning to the economic benefit and minimizing plastic pollution improving Plastics Industry.
Glass fiber mat reinforced thermoplastic composite (Glass Mat Reinforced Thermoplastic) is called for short GMT, it is a kind of is matrix with thermoplastic resin, with the composite that long glass fibres or continuous glass-fiber felt are reinforcing material, generally make sheet material with semi-finished product supply.Due to its there is high specific strength, high impact properties, lightweight, the plurality of advantages such as molding cycle is short, production efficiency is high, processing cost is low, and become the favor person of auto industry.Compared with same with thermosetting compound material, the matrix of GMT material is thermoplastic resin, is heated to more than the fusing point of matrix resin and can makes material softening.Thus damaged goods in the waste product caused time shaping, leftover pieces and use procedure, through melting down heating, reshaping process, can regain new goods.The regeneration advantage of GMT material is that same with thermosetting compound material cannot be mentioned in the same breath with it, and thus it is called as " the green industry material " of 21 century.
Research at present about GMT MAT'L recycling has many reports, now tests in automobile industry with the scale of batch production, and has achieved good result.Method is substantially as follows: (1) is reclaimed part and is ground into chip, as raw material again for semi-finished product sheet production.As the Azdel GMT material for Jaguar 300 car bumper that U.S. GE Plastics and PPG company produce jointly, be that waste and old bumper uses in 20/80 ratio blending with GMT green wood after reclaiming and pulverizing, then be composited.(2) discarded or broken parts are pulverized, blending is as supporting material together with short glass fiber, makes modified particle through melt extruding, for injection moulding or extruded product.The recovery method about automotive upholstery TRPP composite as mentioned in domestic patent CN1651502A and CN1651503A all have employed this technique.Above-mentioned two kinds of technical schemes are traditional melting regeneration technology, melting reshaping after its Process ba-sis is all and first pulverizes, but this technique still has many deficiencies in concrete implementation and operation process.
With the addition of a large amount of glass composition in 1.GMT material, in crushing process, not only noise is large, and easily produces a large amount of dust pollution, worsens and produces sublimity, cause very large harm to health;
2. disintegrating process is not suitable for light GMT, and when light GMT material is subject to applied shock load, the approach of apparatus with shock absorbing and ability are higher than heavy GMT material.For heavy GMT material, material by collision rift, easily ftractures, broken, in brittle fracture, and deformation to a certain degree can occur light GMT, to resist fracture;
3.GMT material glass composition is large, melt shear resistance is high, and plastics recovery production equipment majority when melt pelletization of prior art does not consider GMT material modification technology, often because of mixing inequality, and cause recycled product poor performance, generally can only make more low-grade plastic products;
4. processing variety is single, and when the machine as reclaimed flexible article reclaims hard product, feeding inconvenience, often damages motor, even screw rod reduction gearbox, and when the machine of common recovery hard product then reclaims flexible article, output is very low.
If use for reference the mixing Characteristics of banbury, first material is carried out fusion plastification by banbury, thus guarantee uniformity and the stability of mixing of materials, again the material after mixing is clamp-oned extruder by force through forced feed machine and carries out extruding pelletization, then effectively can improve that waste or used plastics is plasticated, melting and modification evenness.But in existing banburying extruding technology, banbury and extruder are all separate devices, process respectively separately, not only occupation of land and cost of investment are greatly, and specific energy consumption is many; Simultaneously again because banbury belongs to batch-mixed equipment, be not only difficult to form serialization processing, and different batches material is difficult to reach identical mixing.
Utility model content
The purpose of this utility model is exactly the two continuously mixing feeding units proposing the granulation of a kind of automobile-used waste and old GMT material recovery, this feeding unit not only solves the problem that banbury and extruder can not form serialization processing, but also plasticate effectively improve waste or used plastics, melting, the material feeding ability of equipment is improve while modification evenness, it is made not only to have adapted to feeding in raw material without automobile-used GMT manufacture of materials leftover pieces broken in advance, but also adapted to the reinforced of the waste and old automobile-used GMT recovery part of bulk, thus without the need to pulverizing waste or used plastics, because of noise when avoiding fragmentation, the harm that dust etc. cause labourer, also save processing step simultaneously, reduce production cost.
For achieving the above object, the utility model is achieved through the following technical solutions:
The utility model discloses two continuously mixing feeding units of a kind of automobile-used waste and old GMT material recovery granulation, primarily of the mixing part of material feeding and discharge transport portion composition.Wherein, material feeding kneading part divides and comprises speed-changing driving device, feeding device, two mixing machine barrel, three block rotors, attemperating unit; Discharge transport portion comprises drive screw, singe screw and attemperating unit; And the charging aperture of the discharging opening of the mixing part of material feeding and the single screw extrusion machine of discharge transport portion connects.
