Abstract
The invention relates to a method for recovering and granulating a waste plastic. The method comprises the following steps: allowing the waste plastic to enter an upper fusion chamber of a machine from the feed inlet, heating and fusing the waste plastic in the upper fusion chamber with a hot wind from a heating chamber, stirring a material (the plastic) in the fusion chamber with a stirring rod, and allowing the fused material to flow down from the bottom of the upper fusion chamber; and sucking out air under the effect of a negative pressure of a fan from spacer sleeves which are arranged on the lower part of the fusion chamber to enter the heating chamber for circulating heating, screw pressing the fused plastic and extruding from an extrusion die by going through a screw, cutting the extruded material, and cooling to plastic particles.
Description
Technical field
The invention belongs to technics of reclaim of plastic waste and utilize the field, be specifically related to waste and old plastics to be carried out carrying out behind the heating and melting method of extruding pelletization by hot blast.
Background technology
Plastics are with premium properties such as its light weight, intensity height, corrosion-resistant, easy processing, bringing into play important effect in the economic construction every field, but along with the extensive use of plastics, waste and old process in plastics becomes a difficult problem, waste or used plastics can cause the pollution of environment on the one hand, also can cause simultaneously the waste of resource, especially packing is used plastics, accounts for the waste or used plastics significant proportion.The plastic refuse recycling is one turns waste into wealth, and solves the important channel of ecological environmental pollution.
Technics of reclaim of plastic waste is pulverized after waste or used plastics is handled the field at present, carry out granulation by screw extruder then, the pulverizing noise is big, dust is many, the worker laboring environment is poor, and it is by friction and electrical heating waste or used plastics to be carried out fusion that screw rod is extruded, and therefore whole process energy consumption is big.
Summary of the invention
The objective of the invention is defective at prior art, a kind of method of waste and old recovery plastic granulating is provided, waste or used plastics is heated and carry out extruding pelletization by hot blast by screw rod, the hot blast reusable edible, the waste or used plastics that reclaims need not to pulverize, can prevent too high degraded of plastics temperature in melting process, the recycling energy consumption that reduced of hot blast by the control hot blast temperature.
The present invention is achieved by the following technical solutions: provide and realize that hot blast fusion pelletizing recovered waste plastic device of the present invention, its structure comprise the chamber of getting the raw materials ready, shaft, last melter, frame, puddler, grid, spacer, following melter, helical blade, screw rod, recyclegas inlet, heating element heater, recyclegas inlet, blower fan, extrusion neck ring mold, transmission mechanism.
Waste or used plastics enters the top melter of machine from charging aperture, and the hot blast that enters from heating clamber with waste or used plastics heating and fusion, has puddler to stir material in melter in the melter, and the material after the fusion flows down from the melter bottom; Spacer is arranged at the bottom of melter, and gas enters the heating clamber heating that circulates from the spacer sucking-off under the effect of blower fan negative pressure, and the plastic melt of fusion is extruded from extrusion neck ring mold through screw rod through screw extrusion, and the material after extruding is cut and is cooled to plastic pellet.
Concrete processing step is as follows:
(1) with the waste or used plastics that reclaims from the dog-house input is got the raw materials ready the chamber, close the dog-house door, open the Di Men of feeder compartment, material enters melter;
(2) in the melter, hot blast enters melter from heating clamber material is heated under fan action, the stirring of puddler is simultaneously constantly stirred material, and the aperture plate of the bottom of melter makes not molten part continue heating in the above, and the melt after the fusion falls into the bottom of melter;
(3) in the bottom of melter spacer is arranged, gas sucks the heating clamber heating that circulates from spacer under the effect of blower fan, and the melt of fusion enters the screw rod extruding and then extrudes from the mouth mould under the effect of helical blade;
(4) material of extruding becomes plastic pellet after the cutting cooling.
The invention has the beneficial effects as follows:By hot blast waste or used plastics is heated and fusion, the plastic melt after the fusion carries out extruding pelletization by screw rod, and the waste or used plastics of recovery need not to pulverize, and therefore, has avoided flying upward of noise and dust, has improved workman's working condition; Can prevent too high degraded of plastics temperature in melting process, hot blast reusable edible, its recycling energy consumption that reduced by the control hot blast temperature.
Description of drawings
Accompanying drawing 1 is a hot blast fusion pelletizing recovered waste plastic apparatus structure sketch of the present invention.
The chambers of getting the raw materials ready 1. among the figure, 2. shaft is 3. gone up melter, 4. frame, 5. puddler, 6. grid, 7. spacer 8. descends melter, 9. helical blade, 10. screw rod, 11. recyclegas inlet, 12. heating element heater, 13. recyclegas inlet, 14. blower fans, 15. extrusion neck ring molds, 16. transmission mechanisms.
The specific embodiment
In conjunction with the accompanying drawings, be described as follows:
After material drops into the chamber of getting the raw materials ready earlier, to get the raw materials ready and open the chamber bottom door of getting the raw materials ready after chamber cap is closed, material falls into melter, the hot-air that enters in the last melter chamber of being heated heats, being stirred bar simultaneously stirs, material after the fusion enters down melter by the grid between the upper and lower melter, and on the blade of melter, gas is sucked to enter by blower fan by spacer and reenters melter after heating clamber heats under the melt of fusion under the gravity effect falls into.Melt enters screw rod and extrudes from extrusion neck ring mold by screw rod under the extruding of blade, through cutting back cooling becoming plastic pellet.
Claims (1)
1. the method for a pelletizing recovered waste plastic is characterized in that: the structure of the hot blast fusion pelletizing recovered waste plastic device in the described method comprises the chamber of getting the raw materials ready, shaft, goes up melter, frame, puddler, grid, spacer, melter, helical blade, screw rod, recyclegas inlet, heating element heater, recyclegas inlet, blower fan, extrusion neck ring mold, transmission mechanism down;
Concrete processing step is as follows:
(1) with the waste or used plastics that reclaims from the dog-house input is got the raw materials ready the chamber, close the dog-house door, open the Di Men of feeder compartment, material enters melter;
(2) in the melter, hot blast enters melter from heating clamber material is heated under fan action, the stirring of puddler is simultaneously constantly stirred material, and the aperture plate of the bottom of melter makes not molten part continue heating in the above, and the melt after the fusion falls into the bottom of melter;
(3) in the bottom of melter spacer is arranged, gas sucks the heating clamber heating that circulates from spacer under the effect of blower fan, and the melt of fusion enters the screw rod extruding and then extrudes from the mouth mould under the effect of helical blade;
