Description

Useless PET polyester circular regeneration product line

Technical field

The utility model relates to macromolecule recycling utilization fields, especially useless PET polyester circular regeneration production Line.

Background technique

Anti-grass cloth, insulation quilt quilt cover, sun net, ton bag, the plastic woven bag etc. manufacture, sell both at home and abroad, using at present are knitted Making its material of the raw materials used flat filament of cloth is polypropylene PP or polythene PE, defect be PP or PE ultraviolet resistance difference and intolerant to High temperature, service life is short, and environmental pollution is serious, and PET polyester material has extremely strong anti-ultraviolet property and high temperature resistance, Woven cloths long service life, but that there are glass transition temperatures is higher for its raw material PET polyester, and melt viscosity is smaller, and strand rigidity is big, Molecular rearrangement is slow, to moisture and the great sensibility of temperature during manufacture PET polyester flat, so that professional technique people both at home and abroad Member is not possible to PET polyester being drawn into PET polyester flat at present, makes in particular with useless PET polyester such as waster terylene cloth corner material etc. It is even more extremely difficult to make woven cloths, beyond example, the markets discarding amount such as waster terylene cloth corner material and old terylene clothes material is big, according to related 30,000,000 tons of old clothes amount or more can be recycled in report, China every year at present, and wherein waster terylene clothes doses accounts for 30% or more, adds Woven dacron angle leftover bits and pieces when upper manufacture clothes, annual terylene waste material reaches 10,000,000 tons or more, as can with state-of-the-art Terylene waste material is carried out recycling by process equipment, is the large-engineering benefited the nation and the people.

Utility model content

The purpose of the utility model is to overcome drawbacks described above, using useless PET polyester circular regeneration product line, using useless PET polyester such as Industry Waste woven dacron corner material, spinning waste silk, waster terylene dress material etc. produces various polyester products, and useless PET polyester follows Ring reconstituted product production line has been sequentially arranged granule machine 2 by process flow, conveyer 3, feed bin 4, feeder 5, has exempted from dry screw rod Extruder 6, grade one filter 8, liquid-phase tackifying reaction kettle 9, Melt Pump 14 and secondary filter 13 exempt from dry screw extruder 6 It is connect with vacuum pump A7, liquid-phase tackifying reaction kettle 9 is connect with vacuum pump B11.

Preferably, the granule machine 2 is pulverizer.

Preferably, the conveyer 3 is belt conveyor.

Preferably, the conveyer 3 is air conveyer.

Preferably, described exempt from dry screw extruder 6 to exempt from dry double screw extruder.

The beneficial effects of the utility model are: using useless PET polyester such as Industry Waste woven dacron corner material, spinning factory waste silk, giving up Terylene clothes material etc. viscosifies filtered recycled polyester melt by melting extrusion, can directly manufacture a variety of PET polyester products, If directly manufacture polyester flat is for producing woven cloths, polyester plastic-steel belt is directly manufactured, directly manufacture spunbond staple fiber, directly made Polyester circle silk etc. is made, has that process is short, equipment is terse, less energy consumption, advantage at low cost realize salvage property recycling, have Conducive to the fundamental state policy for economizing on resources and protecting environment is implemented, there is the economic benefit of far-reaching social benefit and enterprise, for The sustainable development important in inhibiting of economy and society.

Detailed description of the invention

Fig. 1 is the production line schematic diagram of the utility model one embodiment；

Specific embodiment

Embodiment is further described below in conjunction with attached drawing:

Referring to Fig.1: 1- feeder, 2- granule machine, 3- conveyer, 4- feed bin, 5- feeder, 6- exempt from dry Screw Extrusion Machine, 7- vacuum pump A, 8- grade one filter, 9-liquid-phase tackifying reaction kettles, 10- heating jacket, 11- vacuum pump B, 12- melt point Piping, 13- secondary filter, 14- Melt Pump；Waster terylene cloth corner material, waster terylene dress material or spinning waste silk, through go-no-go by upper Material machine 1 is manually fed into granule machine 2 or pulverizer, is ground into particle through granule machine 2 or is ground into particle using pulverizer, It is sent to feed bin 4 through conveyer 3, conveyer 3 uses belt conveying or vacuum handling, and the terylene particulate material in feed bin 4 is through feeding The feeding of material machine 5 exempts from dry screw extruder 6, and terylene particulate material melted by heating in exempting from dry screw extruder 6 is exempting from dry spiral shell Air and aqueous vapor are taken away by vacuum pump A7 in bar extruder 6, melt extrusion, which filters off inorganic contaminants by grade one filter 8, to be become PET polyester is come into being melt, this nascent melt viscosity is relatively low, containing more organic impurities, is unable to satisfy manufacture PET polyester The requirement of flat filament and other PET polyester articles, therefore the nascent melt of PET polyester is sent into liquid-phase tackifying reaction kettle 9, liquid-phase tackifying It is connected with vacuum pump B11 on reaction kettle 9 to vacuumize, liquid-phase tackifying reaction kettle 9 is equipped with heating jacket 10, nascent to PET polyester Melt is heated, PET polyester come into being melt in liquid-phase tackifying reaction kettle 9 under the action of high temperature and condition of high vacuum degree, melt The moisture of middle remnants and the lower-molecular substance of organic decomposition object are extracted, in the condition of high temperature and condition of high vacuum degree, PET polyester point Son, which carries out polycondensation reaction, increases regenerative PET PET conglutination, and the PET polyester fondant after viscosifying is pressurized through Melt Pump 14 again through two Grade filter 13 filters off subtle inorganic impurity, and the PET polyester fondant after this thickening is close to or up to primary PET polyester slice Then the performance of melt goes out to carry out various subsequent PET polyester products again from melt distribution pipe 12 into melt distribution pipe 12 Production, such as produce spunbond staple fiber, melt is directly entered numerous spinning nozzles from melt distribution pipe 12, such as produces PET polyester Flat filament can be directly entered flat film die, and round silk spinneret die can be directly entered by such as producing PET polyester circle silk, and such as producing plastic-steel belt can It is directly entered flat poroid die head, this pre-crystallized, dry, the melting that can directly save when complicated polyester slice makees raw material is squeezed Equal processing apparatus out, this technique saves many equipment and power consumption, while avoiding the secondary degradation of PET polyester, raw Production is short with process, equipment is terse, less energy consumption, advantage at low cost, realizes salvage property recycling.
