Abstract
The utility model discloses an exhaust-type single-screw waste plastic reclamation extruder comprises a power device (1), a feed hopper (2), a machine barrel (3), and an air-cooler (4). The reclamation extruder is characterized in that an exhaust-type single screw (8) is arranged in the machine barrel (3); an exhaust section (9) is arranged at the middle part of the exhaust-type single screw (8); and an exhaust hole (10) is formed on the wall of the machine barrel (3) in the position corresponding to the exhaust section (9). The exhaust-type single screw waste plastic reclamation extruder has the advantages that the exhaust-type single screw adopts a larger length-diameter ratio, so that the depth of the screw channel of the screw exhaust section is larger, thereby improving the exhaust effect; the melt is extruded after the exhaust process, thereby having high density and meeting the requirement of directly producing agricultural trickle irrigation tapes through reclaimed plastic materials or powders; and the waste plastics are used to produce the trickle irrigation tapes, thereby reducing the manufacturing cost, and solving the problems that the waste plastics can not be recycled and the environment is polluted.
Description
Technical field
The utility model relates to a kind of technics of reclaim of plastic waste machine-shaping device, and particularly a kind of exhaust list screw rod technics of reclaim of plastic waste extruder is applicable to that the drip irrigation zone produces.
Background technology
Be used for the plastic processing extruder that the drip irrigation zone produces at present, comprise power set, loading hopper, machine barrel, screw rod, fuselage, air-cooler constitutes, power set are located at feed end, and fix with machine barrel, connect the drip irrigation zone former at the discharge end of machine barrel, the discharge end of machine barrel is fixed by gripper shoe, outside machine barrel, be surrounded by the electrical heating cover, screw rod is located in the machine barrel, after fixing material adds in the loading hopper, under the effect of screw rod rotation, rubbing action by machine tube inner wall and screw surface, material is fed forward and compacting, and material produces frictional heat in the process of advancing, and material is progressively raise along machine barrel temperature forward.Under the effect of machine barrel dispatch from foreign news agency heating jacket, make material become the fluid state of fusion, enter drip irrigation zone former moulding again.The extruder that is used to reclaim plastic processing at present mostly is twin-screw greatly, film fragments is pressed into by screw compulsory, the deficiency of this extruder is: because the length of twin-screw is short, screw thread is shallow, draw ratio is little, so can not effectively discharge moisture, make to extrude to occur pore on the drip irrigation zone, influence the quality of drip irrigation zone; For preferably the moisture in the waste or used plastics being got rid of, prevent to extrude and occur quality problems such as pore, bubble on the drip irrigation zone, normal at present the plastics extrusion screw rod that adopts with exhaust structure, but the present single-screw extruder that uses, the draw ratio of its single screw rod is also less, in 30: 1,, can not make and reclaim plastics or the agricultural drip irrigation zone of the direct production of powder so cause exhaust effect not ideal enough.
Summary of the invention
The utility model purpose is to provide a kind of and has good exhaust effect, can improve the exhaust list screw rod technics of reclaim of plastic waste extruder of the drip irrigation zone quality of production.
For reaching above purpose, the technical scheme that the utility model adopted is: this exhaust list screw rod technics of reclaim of plastic waste extruder, comprise power set, loading hopper, machine barrel, air-cooler constitutes, power set are located at feed end, and fix with machine barrel, connect the drip irrigation zone former at the discharge end of machine barrel, the discharge end of machine barrel is fixed by gripper shoe, be surrounded by the electrical heating cover in the outside of machine barrel, it is characterized in that in machine barrel, being provided with exhaust list screw rod, middle part at exhaust list screw rod is provided with exhaust section, with the wall of the corresponding position of exhaust section machine barrel on be provided with steam vent, the draw ratio of exhaust list screw rod is 40: 1-60: 1.The utility model is also implemented by following measure: described steam vent is a bar hole, its length be exhaust list screw rod pitch 2-4 doubly, its width is the 1/2-1/4 of the diameter of exhaust list screw rod.
The beneficial effects of the utility model are: compare with the technics of reclaim of plastic waste extruder of present use, because exhaust list screw rod adopts bigger draw ratio, screw rod exhaust section spiral groove depth is bigger, after the plastics of basic plasticizing are entering the screw rod exhaust section, because the unexpected intensification of screw channel, pressure is sharply reduced to negative pressure state, in the melt original by compression gas and the volatile ingredient of having vaporized in melt, foam, effect therapeutic method to keep the adverse qi flowing downward follicular rupture at the screw rod exhaust section, overflow by steam vent, thus exhaust effect improved, after the melt of pump-down process is extruded again, the density height can be fit to directly produce with plastics recovery material or powder the requirement of agricultural drip irrigation zone; With waste or used plastics production drip irrigation zone, production cost is reduced, simultaneously, solved also that waste plastics can not be recycled, the shortcoming of contaminated environment.
Description of drawings
Fig. 1 is the utility model structure office cross-sectional schematic.
Fig. 2 overlooks enlarged diagram for the utility model exhaust list screw rod.
The specific embodiment
Make the utility model with reference to accompanying drawing 1,2.This exhaust list screw rod technics of reclaim of plastic waste extruder, comprise power set 1, loading hopper 2, machine barrel 3, air-cooler 4 constitutes, power set 1 are located at feed end, and it is fixing with machine barrel 3, connect drip irrigation zone former 5 at the discharge end of machine barrel 3, the discharge end of machine barrel 3 is fixing by gripper shoe 6, be surrounded by electrical heating cover 7 in the outside of machine barrel 3, it is characterized in that in machine barrel 3, being provided with exhaust list screw rod 8, middle part at exhaust list screw rod 8 is provided with exhaust section 9, with the wall of exhaust section 9 corresponding position machine barrels 3 on be provided with steam vent 10, the draw ratio of exhaust list screw rod 8 is 40: 1-60: 1.Described steam vent 10 is a bar hole, its length be exhaust list screw rod 8 pitch 2-4 doubly, its width is the 1/2-1/4 of the diameter of exhaust list screw rod 8.
Claims (2)
1, a kind of exhaust list screw rod technics of reclaim of plastic waste extruder, comprise power set (1), loading hopper (2), machine barrel (3), air-cooler (4) constitutes, power set (1) are located at feed end, and it is fixing with machine barrel (3), discharge end at machine barrel (3) connects upward drip irrigation zone former (5), the discharge end of machine barrel (3) is fixing by gripper shoe (6), be surrounded by electrical heating cover (7) in the outside of machine barrel (3), it is characterized in that in machine barrel (3), being provided with exhaust list screw rod (8), be provided with exhaust section (9) at the middle part of exhaust list screw rod (8), with the wall of exhaust section (9) corresponding position machine barrel (3) on be provided with steam vent (10), the draw ratio of exhaust list screw rod (8) is 40: 1-60: 1.
