Mouthful, it is connected with band check-valves hollow pin with high voltage bearing pipeline.
The corresponding melt zone of outer sleeve at single screw extrusion machine is suitable with ripening section (about 1/3rd of screw jacket cylinder overall length)
Arranging 3～5 sections, each section takes 6～12 holes symmetrically and evenly, and aperture is about the 12～1/20th of sleeve diameter,
And it is provided with screw thread.In the relevant position arranging section, the spiral shell rib of the driving screw in single screw extrusion machine is excised appropriate section, cuts
Should be than pin diameter big 4～6cm except the opening at position, it is to avoid with the pin generation mechanical collision goed deep in cavity when driving screw rotates.
The diameter of described band check-valves hollow pin is identical with the diameter of single screw extrusion machine perforate, and processes thread, it is simple to regulation
Go deep into the degree of depth of cavity with check-valves hollow pin, be allowed to adapt to the demand of the material characteristic of the different waste or used plastics of processing.
The through hole of the interior brill 6～8mm of pin of supplying gas, the center of circle in hole is concentric with pin, and ensures that wall thickness is at more than 2.5mm.If (machine

On improved chemical, comprise particulate material, powder material, lamellar material, can in modified formula design ratio, uniformly stir with on an equal basis
Ratio is even changed in the main frame cavity sending into comminutor.Controllable discharging opening is opened in the lower section of mixing tank, to ensure that material (i.e. changes
Property medicament) with metering feeding spiro rod feeding demand match.
The feed opening syndeton length of metering feeding spiro rod and improved chemical storage tank is depending on site space position, but is no less than 2m.Meter
The diameter of amount feeding spiro rod typically should be about 1/3rd of main frame diameter, buncher drive.By adjusting engine speed,
Adjustable feeding amount.At decompression end (i.e. in main frame at the melt lateral pressure minimum) opening of the diameter progressive screw of main frame, send with metering
Material screw rod docking, to ensure that improved chemical can enter in comminutor cavity smoothly, makes the melt of waste or used plastics and the molten of improved chemical
Physical ability is sufficiently mixed uniformly.

Fixed required melt temperature so that improved chemical concurrently form in course of conveying ripening, the preferable melt of the uniformity and send into master
In machine cavity body.
The present invention has an advantage highlighted below:
As previously described, because waste or used plastics is impure many, fusing point differs, and needs to clean before regeneration is processed, and raw material is aqueous
Rate is high, and in air, oxygen unavoidably enters comminutor melt.Traditional mode of production mode forms melt also for promoting different component plastics
Reduce melt internal friction, often processing temperature is improved to about 400 DEG C, the highest.Under the high temperature conditions, steam,
Oxygen is very big to the plastic damage of high molecular polymer, exceedes the cracking temperature of plastics, causes serious chain rupture, produces large quantity of exhaust gas
Polluting environment, product becomes fragile, low quality.Protective gas is sent into comminutor with certain pressure by pin of supplying gas by the present invention
In cavity, by point air pressure of protective gas, steam and oxygen are squeezed away, plastic melt is carried out inert gas shielding.From
And avoid the chain rupture of high molecular polymer, make quality be greatly improved.
Melted and the plasticizing uniformity coefficient of plastics depends on (one) processing temperature.During temperature height, plastics melt faster, but mistake
Causing plastics during heat, if the decomposition temperature of polyethylene is 310 DEG C, other plastics are the most substantially at about 310～350 DEG C.(2)
Mechanical friction, stirring, extrude the shear shinning of generation, also make plastics fusion plastification, the effect strengthening mechanical shearing thinning can phase
Processing temperature should be reduced, it is achieved the principle of the machining at low temperature extrusion in plastic processing.The hollow of band check-valves in the present invention is supplied gas
Pin insert in comminutor cavity 12～about 18mm (depending on comminutor spiro edge heights) and and spiral shell rib section have between 2～3mm
Gap.So entering the melt every revolution of the waste or used plastics of melt zone, fluxing zone, just the gap with hollow pin occurs once to squeeze
Pressure, rubbing, total generation tens times (identical with pin radical) is crumpled, is produced great shearing effect, make melt mixed equal
Even.To this end, processing temperature 100～about 150 DEG C can be reduced.(waste or used plastics sum is accounted for as a example by processing waste polyethylene
48%) can ensure that the actual temperature of melt is at 200～220 DEG C.Thus avoid the decomposition temperature of polyethylene 310 DEG C, improve greatly
The physical and chemical performance of regenerated plastics.
It has been observed that the complicated of waste or used plastics, after regeneration, product quality is inferior so that it is uses and is greatly limited.Cause
And modifying plastics development in recent years is swift and violent.By adding plasticizer, increasing flux, activeness and quietness agent etc., improve and improve the product of plastics
Matter is good developing direction.But modifying waste plastic can more uniform mix, often with waste or used plastics melt for making improved chemical
Use the traditional handicraft of " secondary granulation "." secondary granulation " is though can reach purpose that is modified and that improve plastics quality, but its shortcoming
It is:
(1) the waste or used plastics melt as the main body of regenerated plastics is cooled, is a granulated into particulate material, then with improved chemical altogether
Mixed, then hot melt granulation, then the energy consumption of first pass pelletize slatterns virtually.
(2) improved chemical is blended second melting, though can ensure that the percentage ratio of modified formula is effective in proportion with " primary material rice "
Rationally, but many improved chemicals are different with " primary expect rice " fusing point, are difficult to the temperature finding several composition all to adapt to, make modification
Effect must be given a discount, or increases the consumption of expensive improved chemical.
The present invention uses the metering feed system of band heating temperature control device, and improved chemical is pressed formula proportion pretreatment in the apparatus
The melt waste or used plastics melt again with pelleting main machine is become to be mixed in proportion.Collection " pelletize " disposably completes with " modified ", thus
Save the energy consumption of nearly 40%.And waste or used plastics melt temperature and the melt temperature of improved chemical in main frame can be controlled respectively, make
The two is had a role to play, and reaches optimum efficiency.
Why the present invention can realize once modified pelletize, the shear action of the stirring extruding rubbing of the hollow pin that has benefited from supplying gas.
Owing to the melt of improved chemical is to preheat into molten condition, the fusion plastification section at comminutor is clamp-oned, with the waste or used plastics of main frame
Melt mixed, the blended stroke of its mixing stroke ratio " secondary granulation " is short, and temperature is relatively low.But due to the hollow pins of tens
Effect cut off by nail, is equivalent to " rubbing " through tens times after two kinds of melt mixed, extruding, mixes, thus mix homogeneously, reach
Expected effect.And be to carry out under the conditions of gas shield in this mixing so that blending and modifying (include increase and decrease melt, connect skill,
Lightly crosslinked etc.) functioning efficiency is greatly improved.
Another main advantages of the present invention is wide applicability, be suitably adapted for the waste or used plastics such as PE, PP, PET coating materials,
The pretreated processing and fabricating of block.Small investment, good quality of product, energy-saving effect is obvious.(paper is included with polyethylene coating materials
Factory's waste material, booth plastic film for agricultural use, mulch film etc.) as a example by, its effect is as shown in table 1 (under conditions of improved chemical formula is identical).
