Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for separating household waste.

Generally, household waste includes food scraps, iron glass, plastics, etc., and if these wastes are separated and sorted, they can be reprocessed. In particular, if the garbage in the waste is fermented and composted using a composting device, it can be used as compost.

The present invention makes it possible to separate and take out food waste from household waste, for example, and embodiments thereof will be described below with reference to the drawings.

Reference numeral 1 denotes a conveyor for transporting waste crushed by a crusher, and the iron pieces are separated by a magnetic separator 2 provided at the tip of the conveyor 1 and stored in a first storage box 3. The others are discharged onto the vibrating feeder 4, where they are separated into large and small shapes. This feeder 4 has an upper sliding surface 5 and a lower sliding surface 6 in which sorting holes are bored, and plastic pieces that are difficult to crush with a crusher remain on the upper sliding surface 5.
This plastic piece is received into the second storage box 7 from the tip of the upper sliding surface 5. Other small objects fall through the sorting hole onto the lower sliding surface 6, and are quantitatively transferred to the chute 8, which will be described later, due to the vibration effect.
guided by.

The chute 8 is inclined at about 45 degrees in the opposite direction to the feeder 4, and a repulsion wheel 9 rotatably driven by a motor M is provided below the chute 8, and the chute 8 is oriented toward the central axis of the repulsion wheel 9. It is located in The repulsion wheel 9 is provided with a plurality of repulsion plates 11, 11, . . . arranged at equal intervals on the circumferential surface of a drum 10.
Reference numeral 12 denotes a separation chamber formed in front of the repulsion wheel 9. This separation chamber 12 is mainly formed by an arcuate guide plate 13 forming an upper wall and a front wall. extends in the tangential direction of the repulsion wheel 9, that is, in the direction perpendicular to the surface of the chute 8, and the tip of the guide plate 13, which serves as the front wall, has a small radius of curvature and is reversed approximately 180 degrees and inclined rearward. ing.

14 is a partition plate vertically installed in front of the separation chamber 12;
This partition plate 14 separates the separation chamber 12 into a first separation chamber 15 at the front and a second separation chamber 16 at the rear, and the front and rear chambers 15 and 16 communicate with each other at the upper part. In the lower part of the first separation chamber 15, a first
A separation port 17 is opened, and a second separation port 18 is opened at the bottom of the second separation chamber 16. Said first
Separation flow passages 19 whose inclination directions are alternately changed are connected to the separation port 17 , and one end of a duct 21 that communicates with a blower 20 is opened in the middle of this flow passage 19 , and the air from the blower 20 is passed through the ducts 21 , 21 , and 21 . It flows into the second separation chamber 16 through the separation flow passage 19 and the first separation chamber 5 .

A third storage box 22 for storing glass pieces with a high coefficient of repulsion is connected to the lower end of the separation flow passage 19, and a fourth storage box 23 for storing garbage with a low coefficient of repulsion is connected to the second separation port 18. A duct 25 communicating with the cyclone 24 is connected to the upper part of the fourth storage box 23.

26 is a fin provided at the upper end of the partition plate 14;
The fins 26 are provided so as to be inclined forward and upward, and change the flow of air rising vertically from the first separation port 17 into the first separation chamber 15 to the front and upward direction. turbulence is generated in the flow.

The present invention has the above configuration, and when the waste crushed by the crusher is discharged onto the conveyor 1, the iron pieces in the waste are accommodated in the first storage box 3 with the magnetic separator 2. Others are discharged onto the feeder 4.

In the feeder 4, a large plastic piece remains on the upper sliding surface 5, and this plastic piece falls from its tip and is stored in the second storage box 7. Smaller shapes of other shapes fall through the sorting holes onto the lower sliding surface 6, which are quantified by the vibration action and discharged onto the chute 8.

Waste discharged onto chute 8
It falls along the top onto the repulsion wheel 9 below. The waste that has fallen onto the repulsion wheel 9 is removed by the rotating repulsion plates 11,1.

guided by.

On the other hand, food waste with a small coefficient of restitution falls in front of the partition plate 14 without passing over the partition plate 14, and
It is stored in the fourth storage box 23 through the separation port 18. Glass pieces are mainly guided to the first separation port 17 described above, but some of these glass pieces have garbage attached to them, and at this time, they are exposed to the air flow rising from the first separation port 17. Therefore, the surface area of the glass piece to which garbage has adhered becomes considerably large compared to its weight, so that it is blown forward and upward by the action of the rising air flow and the partition plate 14.
At this time, the glass to which the garbage has adhered collides with the guide plate 13 on the front wall, and is again guided to the first separation port 17 along the slope of the guide plate 13, thereby moving in an annular manner.

During the movement, garbage adhering to the glass pieces is separated due to the impact when it collides with the guide plate 13 and the turbulence of the air, and the glass pieces alone move against the air flow. Since it falls, it passes through the separation flow path 19 and is accommodated in the third storage box 22 .

On the other hand, since the garbage separated from the garbage pieces becomes lighter, it is guided to the second separation port 18 by the air flow. As described above, in the present invention, the waste to be separated is bounced off by the rotating repulsion wheel, and the waste is separated based on the difference in flying distance, so that separation can be ensured. In particular, those with a large coefficient of repulsion are guided along an arc-shaped guide plate to a predetermined separation port, making it possible to reduce the size of the separation chamber.Furthermore, the base of the guide plate is placed in the tangential direction of the repulsion wheel. When the waste is guided to the separation port by the guide plate, there is no turbulent repulsion, and the target material can be reliably guided to the predetermined separation port.

In addition, since air is allowed to flow in from the first separation port and air is allowed to flow out from the second separation port, the heavy waste that has been blown into the first separation chamber can be further sorted using air, allowing for highly accurate separation. A sorting effect can be obtained.
