Description
Technical field
The present invention relates to a kind of plastic processing device, particularly relate to a kind of new polyester recovery and reusing and recycling device, belong to resource regeneration field.
Background technology
Along with the continuous growth of World Economics, particularly China's economic tell development, countries in the world are to being that the demand had constantly increases, hold at high price, China is experimental branch line state the biggest in the world, the rise of oil price, and chemical fibre raw material follows rise, there is loss in domestic chemical fibre manufacturer large area, therefore waste material is all reclaimed for regenerative ratio in active research exploitation in countries in the world.
Process from polyester bottle slice to chemical fibre is the maximum field of Pillar recovery use amount, due to the quality problems of Pillar recovery bottle sheet itself, use at present for chemical fibre field is only limitted to short silk aspect, be mainly used in three aspects, that is: for controlling fiber-filled material in three-dimensional of weaving, for making low and middle-grade non-woven fabrics raw materials, to weave low-grade chemical fabric for cotton mill.Domestic feed back spins that short silk actual consumption is substantially saturated, and each producer is in low-grade race condition substantially, and feed back spins that short silk is substantially profitless to be sayed.
In these cases, polyester bottle slice is improved the grade, increase value-added content of product, this is the problem be placed under China's standing state, polyester bottle slice is all used for polyester filament in research and produces by current domestic Duo Jia manufacturer, namely spins POY long filament, but does not also have successful precedent.
By polyester bottle slice by special in granulation; reach and spin terylene POY filament requirement; have a high potential; reach and spin terylene POY filament requirement, a key issue must be solved---viscosity, if polyester bottle slice by the section out of general comminutor; the viscosity of bottle sheet not only can not improve; can decline on the contrary, this phenomenon is called in experimental branch line falls Jie, so do not make viscosity reduce in granulation process or the subject matter of to be viscosity increase in granulation process be current solution.
Summary of the invention
In order to solve the problem, the invention provides a kind of polyester bottle slice reclaiming device.Increase the viscosity of Pillar recovery bottle sheet, substantially reach the requirement spinning terylene POY filament.
Technical scheme of the present invention is: a kind of polyester bottle slice reclaiming device, comprise feed hopper, gear-box, barrel, heat block and screw rod, feed hopper is arranged on barrel front end, heat block is evenly arranged on around barrel, and with heat-insulation layer, heat block is fixed on barrel outer wall, and screw rod is arranged at barrel inside, screw axis is overlapping with barrel axis, gear-box is arranged at cartridge front portion top, and is connected with screw rod, and barrel is fixed on working foundation with support.
Further, described feed hopper is horn-like, and slot end accesses barrel with tangential direction, and the level inclination of described feed hopper is 40-60 degree.
Further, described barrel is cylindrical, and at barrel 1/2 place to barrel end, arrange the exhaust hole of more than 3-5, exhaust hole internal diameter is 20mm-80mm, especially 30mm-50mm; Exhaust hole is connected with vavuum pump.
Further, in order to ensure work negative pressure, described vavuum pump work produces negative pressure and is not more than 200pa, and vavuum pump duty be intermittently, twice start-up time interval be not more than 30min.
Further, described screw rod is double-screw structure, twin-screw spacing 20-50mm, and the root footpath of screw rod is than being 1:0.4-0.7, and draw ratio is 1:38-45, and material is SUS304, SUS316 material.
Further, described double-screw structure, twin-screw spacing 20-50mm, screw flight angle is 55 degree.
Further, described inner gear of the gear box is connected with decelerator, gear driven screw speed 100-300r/min.
Polyester bottle slice reclaiming method, import department's temperature of barrel is 275-285 DEG C; The outlet temperature 260-270 DEG C of barrel.Twin-screw spacing 20-50mm, screw flight angle is 55 degree.Barrel 1/2 place is to barrel end, and arrange the exhaust hole of more than 3-5, exhaust hole internal diameter is 20mm-80mm, especially 30mm-50mm; Described vavuum pump work produces negative pressure and is not more than 200pa, and vavuum pump duty be intermittently, twice start-up time interval be not more than 30min.
Described inner gear of the gear box is connected with decelerator, gear driven screw speed 100-300r/min.
The invention has the beneficial effects as follows: the viscosity that 1, effectively can increase polyester bottle slice raw material, the section after granulation can be used for spinning terylene POY filament and produces, and improves added value of product; 2, can effectively improve inlet amount and disposal ability, control the thickness outpouring tape; 3, effectively can improve mixed effect, kinetic equation loss is little, extends the service life of screw rod.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of new polyester reclaiming of the present invention device:
In figure: 1, feed hopper, 2, barrel, 3, heat block, 4, muff, 5, steam drain, 6, support, 7, screw rod, 8, gear-box.
Detailed description of the invention
Below with reference to the accompanying drawings and specific embodiment, the present invention is further illustrated:
As shown in the figure, a kind of polyester reclaiming device, comprises feed hopper 1, barrel 2, heat block 3 and screw rod 7, and feed hopper 1 is arranged on barrel 2 front end, and feed hopper 1 is horn-like, and slot end is with tangential direction access barrel 2, and the level inclination of feed hopper 1 is 50 degree.
Heat 3 pieces to be evenly arranged in around barrel 2, and with heat-insulation layer 4, heat block 3 is fixed on barrel 2 outer wall, heat-insulation layer 4 selects silicate heat insulation glass cotton to be incubated, and is incubated by all for barrel 2 outer walls.
It is inner that screw rod 7 is arranged at barrel 2, and screw rod 7 axis is overlapping with barrel 2 axis, and screw rod is double-screw structure, twin-screw spacing 50mm, and root footpath is than being 1:0.5, and draw ratio is 1:40, and material is SUS316 material, twin-screw spacing 40mm, and screw rod angle is 55.
Gear-box 8 is arranged at 1/2 place of barrel 2, arranges the exhaust hole of 3, and exhaust hole internal diameter is 40mm, and enterprise's roller box internal gear is connected with decelerator, gear rotational speed 200r/min.
Finally with support 6, barrel 2 is fixed on working foundation.
After pending polyester bottle slice is tentatively pulverized, entered by the tangential direction of feed hopper 1 from barrel 2, now because charging and barrel 2 enter in tangent line, under the drive of screw rod 7, homogeneous band feeding cylinder 2 is inner, avoid blocking and uneven charging phenomenon, device treatment effeciency stability can be improved to a great extent.
After waste material enters barrel 2, heat block 3 pairs of barrels 2 heat up, and under the effect of muff 4, reduce heat-energy losses, the reaction temperature of constant waste material, screw rod 7 is under the drive of gear-box 8, extrude with the rotating speed of 200r/min, make the moisture in polyester bottles depart from polyester bottles strand.
Simultaneously, vavuum pump starts, form the negative pressure within 200Pa to exhaust hole 5, by the moisture sucking-off existed in barrel 2, sucking-off is complete, vavuum pump quits work, again there is water to be squeezed out polyester bottle slice molecule in barrel 2, again start vavuum pump, and so forth, until polyester bottle slice completes processing procedure, discharge barrel 2.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
