The problem of use was raised.

Accordingly, various technologies for collecting and recycling synthetic resins that are discarded in recent years have been provided.

Looking briefly at the configuration of the treatment device used to recycle waste synthetic resin as described above, there is a melt transfer unit installed with a hopper for inputting waste synthetic resin including waste vinyl on one side, and inside the melt transfer unit to transfer the waste synthetic resin. Screws with a number of blade pieces are installed on the outer circumferential surface. In addition, a heating chamber with a burner is installed at the lower end of the melt conveying unit, and the waste synthetic resin conveyed along the screw is heated to melt into a gel shape, and then discharged to the outside through an outlet.

However, in the conventional treatment apparatus as described above, the peeling of vinyl or paper contained in the injected synthetic resin is put together, and it is melted together during the melting process and the quality is degraded. there was.

In addition, in order to solve the above problems, various sorting and processing devices have been proposed, and most of these devices have problems such as having to perform each process separately, since most of these devices are configured separately.

Thereafter, referring to FIG. 8 again, in the second transfer unit 500, the crushed material 20 stored in the second storage hopper 510 is separated through the second transfer pipe 520 by the operation of the second transfer screw 521. (600) It is transferred upward to the top and is supplied to the sorting part input hopper 624 of the sorting part input means 620 of the sorting part 600.

Thereafter, in the sorting part 600, referring to FIG. 11, first, the crushed material 20 input from the sorting part input means 620 through the input screw 623 is transferred and put into the upper part inside the sorting part main body 610. .

At this time, the crushed material 20 injected into the upper part of the sorting part main body 610 is dropped by the rotational separator 630 and separated into a synthetic resin piece 21 and a peeling layer 22, and the synthetic resin pieces 21 and the peeling material ( When the crushed material 20 mixed with 22) falls onto the rotating separation plate 631, it is hit by the rotating separation blades 632 and 632', and the synthetic resin pieces 21 and the skin 22 are scattered and separated from each other. It will be.

At this time, the synthetic resin piece 21 having a heavy specific gravity among the synthetic resin pieces 21 and the peeling 22 separated as described above is moved to the bottom by the inclination and centrifugal force of the rotating separator 631 and inside the separating unit main body 610. By being hit on the side, the hitted synthetic resin piece 21 falls to the bottom through the piece dropping space G, and is discharged through the piece discharge port 611 to be collected in a separate collection means.

Meanwhile, a small amount of peeling 22 may be included in the synthetic resin piece 21 falling into the piece dropping space G as described above. In this case, in the present invention, a fall prevention blade 633 formed on the bottom surface of the rotating separation plate 631 ) (633') to generate wind around the perimeter or hit the peeling (22) to prevent the peeling (22) from falling downward through the piece dropping space (G), which is a piece of falling space by the wind. The peeling 22 discharged to (G) is raised by the suction force of the suction blower 640 together with the air introduced into the air inlet hole 613.

And the peeling 22 of paper or vinyl having a small specific gravity is moved upward with the air introduced into the air inlet hole 613 by the suction force of the suction blower 640 and discharged through the suction blower 640 ( 641), which is then collected in a separate collection means.

At this time, in the present invention, a suction amount control damper 612a is configured inside the skinning outlet 612, and the type of the skinning 22 by controlling the opening and closing amount of the skinning outlet 612 by the suction amount adjusting damper 612a. It is configured to be able to adjust the suction amount according to.

On the other hand, in the present invention, with reference to FIG. 7, when a guide protrusion 615 is further included on the inner circumferential surface of the sorting unit main body 610 to reach the end of the skinning outlet 612, the suction force of the suction blower 640 The air introduced into the air inlet hole 613 by the spiral guide protrusion 615 forms a swirling flow at the top of the rotary separation unit 630, whereby the peeling 22 is a swirling flow with air. It is guided and discharged quickly and smoothly to the top along the line.

Meanwhile, in an embodiment of the present invention, the input conveyor 100, the crushing part 200, the first conveying part 300, the friction separation part 400, the second conveying part 500, and the sorting part ( Although the continuous operation of 600) has been described, this is not limited and it is natural that each operation can be performed through each drive.

As described above, the waste synthetic resin peeling removal and sorting system of the present invention enables efficient crushing and separation of waste synthetic resin through the continuous construction of the crushing part, the friction separation part, and the sorting part.In particular, paper or vinyl attached to the waste synthetic resin through the sorting part. With the effective separation of, only pure synthetic resin pieces can be obtained.
