Description
Technical field
The present invention relates to a kind of plastic processing device, relate in particular to a kind of new polyester reclaiming use device, belong to the resource regeneration field.
Background technology
Continuous growth along with World Economics, particularly China's economic tells development, countries in the world are to being that the demand that has constantly increases, to hold at high price, China is chemical fibre producing country the biggest in the world, the rise of oil price, and chemical fibre raw material is followed rise, loss appears in domestic chemical fibre manufacturer large tracts of land, so countries in the world are all reclaimed waste material in the active research exploitation and are used for producing again.
Process from the polyester bottle slice to the chemical fibre is the field of reclaiming polyester use amount maximum, owing to reclaiming the quality problems of polyester bottle slice itself, the use that is used at present the chemical fibre field only limits to short silk aspect, be mainly used in three aspects, that is: be used for the weaving three-dimensional and control the fiber-filled material, be used for making low and middle-grade nonwoven raw materials, be used for the low-grade chemical fabric of cotton mill weaving.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 substantially profitless saying of short silk.
In these cases, polyester bottle slice is improved the grade, increase value-added content of product, this is a problem that is placed under China's standing state, domestic many manufacturers all are used for polyester filament production in research with polyester bottle slice at present, namely spin the POY long filament, but also do not have successful precedent.
With polyester bottle slice by special in granulation; reach and spin the terylene POY filament requirement; have a high potential; reach and spin the terylene POY filament requirement, must solve a key issue---viscosity, if polyester bottle slice by the section out of general comminutor; the viscosity of bottle sheet not only can not improve; can descend on the contrary, this phenomenon is called in chemical fibre production falls Jie, so do not make reduced viscosity in the granulation process or be that the viscosity increase is the subject matter of current solution in granulation process.
Summary of the invention
In order to address the above problem, the invention provides a kind of polyester bottle slice reclaiming device.Increase the viscosity that reclaims polyester bottle slice, substantially reach the requirement of 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 the barrel front end, heat block evenly is arranged on around the barrel, and with heat-insulation layer heat block is fixed in the barrel outer wall, and screw rod is arranged at barrel inside, screw axis and barrel axis are overlapping, gear-box is arranged at the anterior top of barrel, and is connected with screw rod, and barrel is fixed in working foundation with support.
Further, described feed hopper is horn-like, and the slot end accesses barrel with tangential direction, and the level inclination of described feed hopper is the 40-60 degree.
Further, described barrel is cylindrical, and is terminal to barrel at barrel 1/2 place, and 3-5 above exhaust hole is set, and the exhaust hole internal diameter is 20mm-80mm, especially 30mm-50mm; Exhaust hole is connected with vavuum pump.
Further, in order to guarantee the work negative pressure, described vavuum pump work produces negative pressure and is not more than 200pa, and the vavuum pump duty be intermittence, twice start-up time the interval be not more than 30min.
Further, described screw rod is double-screw structure, and directly than being 1:0.4-0.7, draw ratio is 1:38-45 for twin-screw spacing 20-50mm, the root of screw rod, and material is SUS304, SUS316 material.
Further, described double-screw structure, twin-screw spacing 20-50mm, the 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.

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: 1, can effectively increase the viscosity of polyester bottle slice raw material, the section after the granulation can be used for spinning terylene POY filament production, improves added value of product; But 2 Effective Raise inlet amount and disposal abilities, control outpours the thickness of tape; But 3 Effective Raise mixed effects, kinetic equation loss is little, prolongs the service life of screw rod.
Description of drawings
Fig. 1 is the schematic diagram of a kind of new polyester reclaiming of the present invention device:
Among the figure: 1, feed hopper, 2, barrel, 3, heat block, 4, muff, 5, steam drain, 6, support, 7, screw rod, 8, gear-box.
The specific embodiment
The 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 installed in barrel 2 front ends, and feed hopper 1 is horn-like, and the slot end is with tangential direction access barrel 2, and the level inclination of feed hopper 1 is 50 degree.
Heat 3 and be evenly arranged in around the barrel 2, and with heat-insulation layer 4 heat block 3 is fixed in barrel 2 outer walls, heat-insulation layer 4 selects silicate heat insulation glass cotton to be incubated, and barrel 2 all outer walls are incubated.
Gear-box 8 is arranged at 1/2 place of barrel 2, and 3 exhaust hole is set, and the exhaust hole internal diameter is 40mm, and enterprise's roller box internal gear is connected gear rotational speed 200r/min with decelerator.
With support 6 barrel 2 is fixed on the working foundation at last.
After the preliminary pulverizing of pending polyester bottle slice, entered by the tangential direction of feed hopper 1 from barrel 2, enter because charging and barrel 2 are tangent line this moment, under the drive of screw rod 7, homogeneous band feeding cylinder 2 inside, avoided stopping up and inhomogeneous charging phenomenon, can improve to a great extent device treatment effeciency stability.
After waste material entered barrel 2,3 pairs of barrels 2 of heat block heated 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, rotating speed with 200r/min pushes, and makes the moisture in the polyester bottles break away from the polyester bottles strand.
Simultaneously, vavuum pump starts, exhaust hole 5 is formed 200Pa with interior negative pressure, and with the moisture sucking-off of barrel 2 interior existence, sucking-off is complete, vavuum pump quits work, again there is water to be squeezed out the polyester bottle slice molecule in the barrel 2, again starts vavuum pump, and so forth, until polyester bottle slice is finished processing procedure, discharge barrel 2.
Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
