As shown in the figure, the device configuration of the present invention is installed so that the ultra-high molecular PE screen 1 into which the primary sorted waste is put is located on the top of the fine foreign matter separating device.

The ultra high molecular PE screen 1 is installed to be inclined low on one side and low on the other side.

In addition, the rotation direction of the ultrahigh molecular PE drive body 11 constituting the ultrahigh molecular PE screen 1 rotates the shaft 12 equipped with the ultrahigh molecular PE drive body 11 so as to rotate from the inclined low side to the high side. Rotation of the shaft 12 connects the neighboring shafts with a connecting means such as a chain (not shown), and rotates it with a motor (not shown) that transmits a driving force to the chain.

The principle of sorting the ultra-high molecular PE screen 1 is to install a plurality of ultra-high molecular PE drives 11 at regular intervals on one shaft, and to install a plurality of ultra-high-molecular PE drives 11 installed on neighboring shafts 12. Is installed by adjusting the interval so as to stagger between the ultra-high molecular PE drive body 11 is installed in the adjacent shaft (12). At this time, the interval between the ultra-high molecular PE drive unit 11 may be installed by adjusting the interval so as to have an appropriate interval according to the type of waste to be sorted. Similarly, the spacing between neighboring shafts may be adjusted according to the type of waste to be sorted.

The gap adjusting method may be performed by inserting spacers having various gaps between the ultrahigh molecular PE drive bodies 11 or by setting an arbitrary gap without the spacers to fix the ultrahigh molecular PE drive bodies 11 inserted into the shaft. do.

When the suction nozzle 52 suctioned through the suction port is installed and the suction force is provided by the operation of the blower 51, the moving speed of the conveyor belt of the lower conveyor 4 is accelerated (high speed). ) Is transferred to the upper side through the lower conveyor (4) and is discharged to the lower side, foreign substances (vinyl, styro product, etc.) that are relatively light in weight are not discharged and the eccentric type through the suction nozzle (52) by the suction force of the blower (51). It is configured to be sucked into the cyclone (5).

In this case, a blower (not shown) having a wind power of about the fan level is installed on the upper part of the lower conveyor to prevent foreign substances (styrofoam, vinyl, etc.) that are light in weight from being discharged through the lower conveyor. The load is prevented, and the suction power of the suction nozzle is too strong to prevent suction to the recycled aggregate.

On the other hand, the eccentric cyclone (5) is a device for inhaling and discharging fine foreign matter in the waste dropped to the lower conveyor lower part of the lower garbage box (6) in which the vacuum is maintained while rotating downward by the rotational force of the eccentric cyclone (5) After being separated and stored in the air, the air is sent to the garbage storage, and the air from which the foreign matter is removed is sent to the blower 51 through the upper passage, and the wind is generated in the blower 51 to pass through the ultra high molecular weight PE screen (1). It is configured to separate the foreign matter by blowing the waste away from the end.
