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 field, be specifically related to by hot blast, waste and old plastics be carried out carrying out after heating and melting the method for extruding pelletization.
Background technology
The premium properties such as plastics are light with its quality, intensity is high, corrosion-resistant, easy processing, in economic construction every field, play an important role, 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 the waste of resource, especially packing plastics, account for waste or used plastics significant proportion simultaneously.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 processed field at present, then by screw extruder, carry out granulation, pulverizing noise is large, dust is many, worker laboring environment is poor, and Screw Extrusion is, by friction and electrical heating, waste or used plastics is carried out to melting, and therefore whole process energy consumption is large.
Summary of the invention
The object of the invention is the defect for prior art, a kind of method of waste and old recycled plastic granulation is provided, by hot blast, waste or used plastics heated and carry out extruding pelletization by screw rod, hot blast reusable edible, the waste or used plastics reclaiming is without pulverizing, by controlling hot blast temperature, can prevent that plastics excess Temperature in melting process from degrading, recycling of hot blast reduced energy consumption.
The present invention is achieved by the following technical solutions: provide and realize hot blast melting recovery prilling device for waste plastic of the present invention, its structure comprises the chamber of getting the raw materials ready, shaft, upper melter, frame, puddler, grid, spacer, lower melter, helical blade, screw rod, recyclegas entrance one, heating element heater, recyclegas entrance two, blower fan, extrusion neck ring mold, transmission mechanism.
Waste or used plastics enters the top melter of machine from charging aperture, the hot blast entering from heating clamber by waste or used plastics heating melting, has puddler turning over materials in melter in melter, and the material after melting flows down from melter bottom; Spacer is arranged at the bottom of melter, and gas enters heating clamber from spacer sucking-off and carries out circulating-heating under the effect of blower negative pressure, and the plastic melt of melting is extruded through screw rod through screw extrusion from extrusion neck ring mold, the cut plastic pellet that is cooled to of material after extruding.
Concrete technology step is as follows:
(1) waste or used plastics of recovery is dropped into and got the raw materials ready chamber from dog-house, close dog-house door, open the chamber Di Men that gets the raw materials ready, material enters melter;
(2) in melter, under fan action, hot blast enters melter from heating clamber material is heated, the simultaneously stirring of puddler makes material constantly make the part of top layer melting fall into the bottom of melter with the grid friction of puddler and melter bottom, and puddle continues to heat in the above;
(3) in the bottom of melter, have spacer, gas sucks heating clamber from spacer and carries out circulating-heating under the effect of blower fan, and the melt of melting is extruded enter screw extruding under the effect of helical blade after from mouth mould;
(4) material of extruding becomes plastic pellet through cutting after cooling.
The invention has the beneficial effects as follows: by hot blast, waste or used plastics is heated and melting, plastic melt after melting carries out extruding pelletization by screw rod, and the waste or used plastics of recovery is without pulverizing, therefore, avoid flying upward of noise and dust, improved workman's working condition; By controlling hot blast temperature, can prevent that plastics excess Temperature in melting process from degrading, hot blast reusable edible, it recycles and has reduced energy consumption.
Accompanying drawing explanation
Accompanying drawing 1 is hot blast melting recovery prilling device for waste plastic structure diagram of the present invention.
1. chambers of getting the raw materials ready in figure, 2. shaft, 3.Shang melter, 4. frame, 5. puddler, 6. grid, 7. spacer, 8.Xia melter, 9. helical blade, 10. screw rod, 11. recyclegas entrances one, 12. heating element heaters, 13. recyclegas entrance two, 14. blower fans, 15. extrusion neck ring molds, 16. transmission mechanisms.
The specific embodiment
By reference to the accompanying drawings, be described as follows:
Material first drops into gets the raw materials ready behind chamber, to get the raw materials ready after chamber cap is closed and open the chamber bottom door of getting the raw materials ready, material falls into melter, the hot-air that the Shang melter chamber of being heated enters heats, be stirred bar stirs simultaneously, material after melting enters lower melter by the grid between upper and lower melter, and under Action of Gravity Field, the melt of melting falls on the blade of lower melter, and gas is sucked to enter after heating clamber heats by blower fan by spacer and reenters upper melter.Melt enters screw rod and extrudes from extrusion neck ring mold by screw rod under the extruding of blade, the cooling plastic pellet that becomes after cutting.
Claims (1)
1. a method for pelletizing recovered waste plastic, is characterized in that: the structure of the hot blast melting recovery prilling device for waste plastic in described method comprises the chamber of getting the raw materials ready, shaft, upper melter, frame, puddler, grid, spacer, lower melter, helical blade, screw rod, recyclegas entrance one, heating element heater, recyclegas entrance two, blower fan, extrusion neck ring mold, transmission mechanism;
Concrete technology step is as follows:
(1) waste or used plastics of recovery is dropped into and got the raw materials ready chamber from dog-house, close dog-house door, open the chamber Di Men that gets the raw materials ready, material enters melter;
(2) in melter, under fan action, hot blast enters melter from heating clamber material is heated, the simultaneously stirring of puddler makes material constantly make the part of top layer melting fall into the bottom of melter with the grid friction of puddler and melter bottom, and puddle continues to heat in the above;
(3) in the bottom of melter, have spacer, gas sucks heating clamber from spacer and carries out circulating-heating under the effect of blower fan, and the melt of melting is extruded enter screw extruding under the effect of helical blade after from mouth mould;
(4) material of extruding becomes plastic pellet through cutting after cooling.
