In addition: the zone of A, B, C indication is respectively transportation section, fluxing zone and melt zone.
The specific embodiment
As shown in Figure 1, extruder of the present invention, comprise: frame 1, frame 1 is provided with barrel 8 and power set, barrel 8 is provided with heater 9, is provided with screw rod 7 in the barrel 8, and described power set comprise: motor 10 and reductor 12, the output shaft of motor 10 links to each other with the power shaft of reductor 12 by shaft coupling 11, and the output shaft of reductor 12 is that the output shaft of power set is connected with an end of screw rod 7; Be provided with corresponding transportation section A, fluxing zone B and melt zone C on barrel 8 and the screw rod 7, the transportation section A of barrel 8 is provided with charging aperture 85---referring to feeding hopper 4 shown in Figure 3 and that match with charging aperture 85, be respectively arranged with steam vent 81 and 82 on the fluxing zone B of barrel 8 and the melt zone C---referring to shown in Figure 2, in the fluxing zone B of screw rod 7 and melt zone C, be respectively arranged with mixing refining head 72 and 73; In the transportation section A of barrel 8 and screw rod 7, be provided with the compression water squeezing structure that cooperatively interacts, its concrete structure is: the end that the transportation section A of screw rod 7 is front fine and rear thick structure and thick section is provided with damping block 71, is provided with between the thickness section to be used to compress the compression cone 74 of material to extrude moisture content---referring to shown in Figure 2; As shown in Figure 3, on the barrel of the transportation section of barrel 8 A, offer many axial rhones 83, be provided with several osculums 84 in every rhone 83---referring to Fig. 4, shown in Figure 5, every rhone 83 all is tilting to be arranged, the direction that makes direction and the material of current advance is opposite.In addition, in order to improve the output of extruder, the length L of described charging aperture 85 is not less than three pitch sums of screw rod 7, and the diameter of its width and barrel 8 is suitable.As Fig. 1, Fig. 6, shown in Figure 7, if the lighter materials such as plastic sheeting of processing bulk density, the a pair of feeding roller that is parallel to each other 6 can be set in described feeding hopper 4, the roll surface of feeding roller 6 is provided with some pointed tooth bars 61, the rotating shaft 62 difference expansion bearings at feeding roller 6 two ends are on the sidewall of the both sides of feeding hopper 4, wherein the rotating shaft 62 of a feeding roller 6 links to each other with the output shaft of reductor 3, and the power shaft of reductor 3 links to each other with the output shaft of motor 2.
Operation principle of the present invention is: waste or used plastics enters into barrel 8 continuously from the charging aperture 85 of feeding hopper 4 process barrels 8, then, entering into fluxing zone B from transportation section A under the promotion of screw rod 7 plastifies, and then enter into melt zone C from fluxing zone B and carry out homogenizing, extrude needed plastic pellet at last.Waste or used plastics is in the course of conveying of transportation section A, because the direction of in the A of transportation section, advancing along waste or used plastics, the diameter of screw rod 7 is by thin chap, cause accumulation during compression cone 74 places of waste or used plastics in arriving screw rod 7, make waste or used plastics by compression cone 74 time, be compressed, extruding, moisture content in the waste or used plastics is extruded, and, screw rod 7 has aggravated extrusion process between waste or used plastics and screw rod 7 and the barrel 8 especially at the damping block 71 of transportation section A end, make more thorough to the extrusion drainage of waste or used plastics, thereby make the water content of waste or used plastics be lower than 5%, satisfy the technological requirement of fluxing zone B; The rightabout that the water that extruding is come out is advanced to waste or used plastics along the rhone 83 on the barrel 8 flows, and discharges in the osculum from be arranged in rhone 83 84.
Because described barrel 8 and screw rod 7 are provided with the compression water squeezing structure that cooperatively interacts in the A of transportation section, make and shortened waste or used plastics greatly from being recovered to the cycle of processing granulating by the wet feed that extruder of the present invention can processing belt water; And make that whole process is safe and reliable.In addition, longer charging aperture 85 can increase and enters into the waste or used plastics amount of barrel 8 from feeding hopper 4 in the unit interval, thereby can improve the output of extruder of the present invention.
