The pay-as-you-go bag (B) is generally formed of plastic. In the present disclosure, if the garbage bag (B) is a bag containing garbage, it may be referred to as a garbage bag (B) regardless of the material of the bag.

Waste (T) may include household waste, recyclables and organic food waste.

The conveyor belt 200 moves at a constant speed, and delivers the shredded garbage bag (B) and waste (T).

Separator 300, if waste (T) is buried in the volume-based garbage bag (B), the volume-based garbage bag (B) wraps the waste (T), so that the waste (T) may not be separated from the volume-based garbage bag (B). Therefore, the waste (T) and the volume-based waste bag (B) are separated. In other words, the waste (T) is shaken from the volume-based waste bag (B).

The trommel screen device 400 may further sever the volume-based garbage bag (B) that is not ruptured by the shredder 100, and classifies the volume-based garbage bag (B) and the waste (T) by size. The volume-based waste bag (B) and waste (T) separated by the separator 300 enter both the trommel screen device 400. The trommel screen device 400 separates the volume-based garbage bag (B) and the waste (T) based on the size of the hole 411 (FIG. 7) of the cylindrical housing 410 (FIG. 7). It is preferable that the size of the hole 411 is 50 to 80 mm.

The disk screen device 500 sorts again according to the size and weight of the volume-based waste bag (B) and waste (T) that have passed through the hole 411 of the trommel screen device 400.

The waste treatment system 1000 is for separating organic matter contained in the waste (T) enclosed in the volume-based waste bag (B), and the organic matter in the volume-based waste bag (B) and waste (T) has a lot of moisture and has a constant size. It does not, and may have a characteristic of being brittle.

The specific gravity of the waste T wrapped in the volume-based waste bag B supplied to the waste treatment system 1000 may have about 0.08 to 0.1.

4 is a diagram illustrating an example of a waste treatment system according to the present disclosure.

The waste treatment system 1000 may include a shredder 100, a separator 300, a trommel screen device 400, a disk screen device 500, a conveyor belt 200 and a loading bin 600.

The volume-based waste bag (B) containing the waste (T) is put into the shredder (100).

The conveyor belt 200 is provided between the shredder 100, the separator 300, the trommel screen device 400, the disk screen device 500, and the loading bin 600.

In the trommel screen device 400, the size of the waste (T) passing through the hole 411 (FIG. 7) and the volume-based waste bag (B) is a conveyor belt 430 provided under the trommel screen device 400; 8) is delivered to the disk screen device 500.

The waste (T) and the volume-based waste bag (B) that did not pass through the hole 411 of the trommel screen 500 come out through the outlet 413 (FIG. 7) and are accumulated in the loading bin 600.

The waste T that has fallen below the disk screen device 500 can be moved to the next process or collected in the loading box 600, and the waste T suspended on the disk screen device 500 is the conveyor belt 200. It can be put in the loading bin 600.

5 is a diagram illustrating an example of a waste treatment apparatus according to the present disclosure.

5 is a view showing an example of the shredder 100, the conveyor belt 200, and the separator 300.

The waste treatment apparatus for processing the waste T wrapped in the volume-based waste bag B may include a shredder 100, a conveyor belt 200, and a separator 300.

The shredder 100 has a funnel-shaped side wall 110, a first rotary blade 101 and a second rotation for crushing the volume-based garbage bag (B) by rotating, and crushing the volume-based garbage bag (B) and the waste (T). Including blade 102. The side wall 110 is provided on the first rotation blade 101 and the second rotation blade 102, and prevents the volume-based garbage bag (B) and waste (T) from going out of the side wall 110, and the volume-based garbage bag (B) and waste (T) can be guided to be crushed by the first rotary blade 101 and the second rotary blade 102. The first rotating blade 101 and the second rotating blade 102 face each other.

The shapes of the first rotary blade 101 and the second rotary blade 102 are different from each other. For example, the first rotating blade 101 may include at least one or more blades 111, and the second rotating blade 102 may be formed to be round. The first rotating blade 101 may include a plurality of blades 111, and the plurality of blades 111 may be provided along the first rotating blade 101 at regular intervals. It is preferable that the shape of the wing 111 is formed in the shape of a hook whose end is bent toward the direction of rotation. The hook-shaped wing 111 rotates while tearing the volume-based garbage bag (B) containing the waste (T), so that the volume-based garbage bag (B) can be easily broken.

The second rotating blade 102 may push the waste T between the first rotating blade 101 and the second rotating blade 102. The second rotary blade 102 is formed in a round shape, so that the blades 111 of the first rotary blade 101 are contained in the garbage bag B between the second rotary blade 102 and the first rotary blade 101. It is possible to push the waste (T) wrapped in the waste (T) and the volume-based waste bag (B) toward the first rotating blade 101 so that the waste (T) can be destroyed.

In detail, a plurality of the first rotating blades 101 may be provided in a row to be integrally formed, and a plurality of the second rotating blades 102 may be provided in a row to be integrally formed. A first rotating blade 101 and a second rotating blade 102 may be provided between the plurality of second rotating blades 102 so that the blades 111 of the first rotating blade 101 can enter. The rotation radius of the first rotation blade 101 and the rotation radius of the second rotation blade 102 may be positioned to partially overlap each other. Through this, the waste (T) and the volume-based waste bag (B) can be crushed efficiently.

In addition, the first rotary blade 101 and the second rotary blade 102 are each rotated, and can be controlled at different speeds. The rotational speed of the first rotational blade 101 and the rotational speed of the second rotational blade 102 may be differently formed. The rotational speed of the first rotational blade 101 and the rotational speed of the second rotational blade 102 may be adjusted according to the size of the volume-based waste bag (B) and waste (T), and may be adjusted according to the season, It can be adjusted according to the organic matter content. For example, when a waste containing a lot of organic matter (T) is wrapped in a volume-based trash bag (B), the first rotating blade depending on the case where a waste (T) that does not contain a large amount of organic matter is wrapped in a volume-based waste bag (B). The speed of 101 and the second rotary blade 102 may be different. In the case of waste T containing a large amount of organic matter, it is preferable that the speed of the first rotary blade 101 is higher than the speed of the second rotary blade 102, and in the case of the waste T containing little organic matter, the It is preferable that the speed of the first rotary blade 101 is slower than the speed of the second rotary blade 102.

It is preferable that the size of the first rotating blade 101 is formed smaller than the size of the second rotating blade 102. The first rotating blade 101 is formed to have a saw blade, and the second rotating blade 102 is preferably formed in a circular shape.

In addition, as the waste T passes between the first rotation blade 101 and the second rotation blade 102, the large waste T may be crushed small. As the speeds of the first rotary blade 101 and the second rotary blade 102 are rotated differently, it is possible to efficiently tear the waste (T) and the volume-based waste bag (B).

The conveyor belt 200 passes the shredder 100 to deliver the shredded waste (T) and the waste mass rate bag (B). The conveyor belt 200 may move at a constant speed.

The separator 300 includes a first rotating body 301 and a second rotating body 302 for separating the delivered waste T and the waste mass-rate bag B. Separator 300 shakes off the waste (T) buried in the garbage bag (B). The first rotating body 301 serves to first shake off the waste (T) from the volume-based garbage bag (B), and the second rotating body 302 secondarily removes the waste (T) from the volume-based garbage bag (B). It serves to shake off. Since the first and the second are shaken twice, the volume-based garbage bag (B) and the waste (T) can be mostly separated. This will be described in detail in FIG. 6. In particular, food waste, which is an organic matter, is well adhered to the volume-based garbage bag (B), household waste and recyclables, among wastes (T), and separates household waste and recyclables and food waste.

6 is a view showing another example of the waste treatment apparatus according to the present disclosure.

6(a) is an example of a plan view of the crusher 100. In the crusher 100, the first rotary blade 101 and the second rotary blade 102 can each rotate at different speeds, which means that the first rotary blade 101 is connected to the first motor 121, and This is because the 2 rotary blade 102 is connected to the second motor 122. It can be seen that the rotation radius of the first rotation blade 101 and the rotation radius of the second rotation blade are formed to overlap each other.

6(b) is a view showing a cross-section AA′ of FIG. 5(a).

The first rotating body 301 of the separator 300 is provided to have a height lower than that of the conveyor belt 200, and the second rotating body 302 is preferably formed higher than the first rotating body 301. Because, by the speed of the conveyor belt 200, the waste (T) and the garbage bag (B) fall while drawing a parabolic line, and the falling impact and the rotational speed of the first rotating body 301 and the first rotating body 301 The uneven surface of the can be used to create a gap between the compressed or stuck waste (T) and the volume-based waste bag (B). The second rotating body 302 can rotate in a counterclockwise direction (Rb) or a clockwise direction (Ra). In the case of rotation in the counterclockwise direction (Rb), when the waste (T) and the volume-based garbage bag (B) pass between the first and second rotors 301 and 302, and rotates in a clockwise direction (Ra). At the top of the second rotating body 302, the waste (T) and the volume-based waste bag (B) passes.

The second rotating body 302 may include a plurality of blades 302-1. The plurality of wings (302-1) may be formed of a piano steel wire with elasticity. The length of the plurality of wings 302-1 may be about 35 to 80 mm, and the thickness may be about 25 to 50 mm.

When the shredded waste (T) and the volume-based garbage bag (B) enter the trommel screen device 400 (FIG. 4) without passing through the separator 300, the waste (T) and the volume-based garbage bag (B) can be separated well. It doesn't work. This is because the waste (T) and the volume-based waste bag (B) are crushed and compressed at the same time. It is difficult to separate the waste (T) and the volume-based waste bag (B) that have entered the trommel screen device 400 without passing through the separator 300 while rotating and are aggregated into a large volume and rolled around and fall into the hole 411 (FIG. 4). Can not fall out of organic matter that can be aggregated and rolled around.

The plurality of wings (302-1) has elasticity, so that the second rotor (302) rotates to push the waste (T) and the volume-based garbage bag (B), and the long shredded garbage bag (B) is a plurality of wings. You may be temporarily caught in (302-1). If the waste (T) is agglomerated between the plurality of wings (302-1) can be broken and escaped.

In addition, the first rotating body 301 and the second rotating body 302 may rotate at different speeds, respectively. For example, the rotation speed may be different according to the waste T containing a lot of organic matter and the waste T containing a lot of organic matter. For example, in the case of waste T containing a large amount of organic matter, the rotation speed of the second rotation body 302 may be faster than the rotation speed of the first rotation body 301. In the case of waste T that does not contain a lot of organic matter, the rotation speed of the second rotation body 302 may be slower than the rotation speed of the first rotation body 301. The first and second rotors 301 and 302 may also be connected to a motor (eg, an inverter motor, not shown), respectively.

It is preferable that the first rotating body 301 rotates in a clockwise direction, and the second rotating body 302 may rotate in a clockwise direction (R) and a counterclockwise direction (R').

The first rotating body 301 is preferably rotated in a clockwise direction because the waste (T) and the volume-based waste bag (B) transferred from the conveyor belt 200 must be transferred to the second rotating body 302. When the second rotating body 302 rotates in a clockwise direction, the transferred waste T and the volume-based waste bag B are transferred onto the second rotating body 302. When the second rotation body 302 rotates in a counterclockwise direction, the transferred waste T and the volume-based waste bag B are transferred to the lower side of the second rotation body 302.

7 is a diagram illustrating an example of a trommel screen device according to the present disclosure.

The trommel screen device 400 may include a cylindrical housing 410 and a cover 420. The cylindrical housing 410 includes an inlet 412, an outlet 413 and a hole 411 formed in the cylindrical housing 410. The waste (T) and the volume-based waste bag (B) entering the cylindrical housing 410 through the inlet 412 are classified according to the size of the hole 411 of the cylindrical housing 410. The cylindrical housing 410 can rotate the center of the inlet 412 and the outlet 413 with a rotational axis, and the cylindrical housing 410 uses the centrifugal force generated by the rotation to use the waste (T) and the volume-based garbage bag (B). Can be classified according to size. Waste T smaller than the size of the hole 411 passes through the hole 411 of the cylindrical housing 410 and is discharged to the outside, and the waste T larger than the size of the hole 411 is discharged to the outlet 413 do. Waste T smaller than the size of the hole 411 may be collected and discharged in one place by the cover 420 surrounding the cylindrical housing 410.

When the rotation axis of the cylindrical housing 410 of the trommel screen device 400 is formed to have an inclination with the floor, the cylindrical housing 410 rotates at 20 to 25 RPM, and it is difficult to rotate at a high speed above 25 RPM, and the weight on one side Since the is pulled, there is a disadvantage that the frictional load of the roller 415 on one side is increased and must be replaced frequently.

To solve this, the rotation axis C of the cylindrical housing 410 of the trommel screen device 400 is formed horizontally with the floor. When the rotation axis (C) of the cylindrical housing 410 is formed horizontally, the internal waste (T) and the volume-based waste bag (B) may not move from the inlet 412 to the outlet 413, so the cylindrical housing 410 ) From the inlet 412 to the outlet 413 along the inner surface of the screw 414 and the blade 416 (see Fig. 9) may be provided. The screw 414 is formed along the inner surface from the inlet 412 to the outlet 413, and the screw 414 is to be transferred from the inlet 412 to the outlet 413 in the waste (T) and the volume-based waste bag (B). I can push it so that I can do it. The blade 416 may further sever the volume-based garbage bag (B), which is not ruptured by the shredder 100, when the volume-based garbage bag (B) is moved to the trommel screen device (400). The blade 416 may be provided in the screw 414 and may be provided in the cylindrical housing 410. In addition, the rotation axis (C) of the cylindrical housing 410 is formed horizontally with the floor, so that it can rotate at high speed at 30 to 50 RPM (maximum 60 RPM). The rotation shaft C of the cylindrical housing 410 is formed horizontally with the floor and can rotate at high speed, thereby increasing the amount of waste T processed per unit time.

8 is a diagram illustrating another example of a trommel screen device according to the present disclosure.

FIG. 8A is a view showing the trommel screen device 400 to the bottom, and a conveyor belt 430 of the trommel screen device 400 is provided below. The waste (T) and the volume-based waste bag (B) passing through the hole 411 of the cylindrical housing 410 of the trommel screen device 400 are formed by the cover 420 of the trommel screen device 400 by a conveyor belt ( It falls on 430, and can move to the disk screen 500 (see FIG. 6) through the conveyor belt 200.

8(b) and 8(c) are views showing that the cylindrical housing 410 of the trommel screen device rotates and the waste T is separated into the hole 411.

As the cylindrical housing 410 of FIG. 8(b) rotates at a high speed, the waste (T) and the volume-based waste bag (B) rise and fall to the top of the cylindrical housing 410, while organic matter in the waste (T) is Small in size and can be broken. Particularly, as it rotates at a high speed, the waste (T) moves to a higher place by the rotational force, and the waste (T) is more impacted as it falls from a higher place, so that it can be easily broken.

As the cylindrical housing 410 of FIG. 8(c) rotates at high speed, organic matters in the waste T may better exit the hole 411 of the cylindrical housing 410. Since the rotational force is increased by the high-speed rotation of the cylindrical housing 410, it is the same as pushing the organic material into the hole 411 by using the rotational force. Since the organic material can be easily broken in shape, it is possible to pass the hole 411 through the rotational force.

9 is a diagram illustrating another example of a trommel screen device according to the present disclosure.

9(a) is an example in which the blade 416 is provided on the screw 414. 9(b) is an example in which the blade 416 is provided around the screw 414.

When the unsealed garbage bag B reaches the screw 414, it may be smashed by the blade 416 provided in the screw 414 at the same time. In addition, the unsealed garbage bag B may be rotated by the cylindrical housing 410 and then broken by the blade 416. Although the shape of the blade 416 is shown in a triangular shape in the drawing, the shape of the blade 416 is not limited as long as it is a blade 416 capable of breaking.

10 is a diagram illustrating an example of a disk screen device according to the present disclosure.

The disk screen device 500 includes a plurality of side walls 510 and a plurality of rotating bodies 540 provided on the side walls 510. Each of the rotating bodies 540 may include a shaft 520 and a plurality of disks 530.

The plurality of sidewalls 510 are formed to face each other. The plurality of rotating bodies 540 may be fixed to be rotatable between the plurality of side walls 510. The plurality of rotating bodies 540 may each rotate, or the plurality of rotating bodies 540 may be connected to rotate together. The rotating body 540 includes a shaft 520 and a plurality of disks 530. The shaft 520 includes an inner space 521 (FIG. 11) and a hole 522. The plurality of disks 530 have a thickness and may be polygonal or circular. The plurality of disks 530 may be fixed to the shaft 520, and a predetermined distance is formed between the plurality of disks 530. It is preferable that the distance between the plurality of disks 530 is greater than the thickness of the disks 530. This is because the disk 530 of the other rotating body 540 must be able to rotate between the plurality of disks 530 provided in one rotating body 540.

The hole 522 formed in the shaft 520 is positioned between the plurality of disks 530. The hole 522 of the shaft 520 discharges air that has entered through the inner space 521 of the shaft 520. The holes 522 are formed at regular intervals along the circumference of the shaft 520, so that air from the shaft 520 can prevent the long strings of waste T from being curled on the shaft 520. Conventionally, when a long string or the like is dried on the shaft 520, the disk screen device 500 is stopped and the long string, etc., which is rolled on the shaft 520 must be manually removed, so it takes a long time and a load is applied to the shaft. there was.

Air is discharged at a constant rate. Vinyl, long strings, light waste (T), etc. can be moved to the rear end of the disk screen device 500 by floating and moving from the shaft 520. The disk 530 sends the raised waste T while rotating to the rear end of the disk screen device 500. It is preferable that the speed of air coming out through the hole 522 is between 0.5 and 1.0 m/min. If it is 0.5m/min or less, vinyl, long strings, light waste (T), etc. may not float well, and if it is 1.0m/min or more, the waste (T) falling below the disk screen device 500 is air Because it can be rich by.

When air constantly comes out through the hole 522, the rotational speed of the disk 530 is preferably between 50 ~ 60RPM. When the rotational speed of the disk 530 is 50RPM or less, vinyl, long strings, light waste (T), etc. may not float well, and when the rotational speed of the disk 530 is 60RPM or more, the disk screen device 500 This is because the waste (T) falling below the can be suspended by air. Light waste T is separated by the air, and heavy organic matter among the waste T may fall between the plurality of disks 530, so that the organic matter in the waste T may be separated once more.

A temperature control unit capable of adjusting the temperature of the air exiting through the hole 522 may be further provided. The temperature controller, for example, may allow air coming out through the hole 522 to have a higher temperature than room temperature. High temperature may be a temperature of 25 degrees or more. If the waste (T) has a lot of moisture, the moisture can be blown away by spraying hot air.

The spacing between the plurality of rotating bodies 540 may be 50 mm. The size of the waste T that goes down the disk screen device 500 is 50 mm or less. It is possible to adjust the size of the waste (T) and the volume-based waste bag (B) falling down by the gap between the end of the disk 530 and the shaft 520. The waste T smaller than the gap is separated from the bottom of the disk screen device 500, and the waste T and the garbage bag B, which are larger than the gap, are provided on the disk screen device 500.

An air supply unit (not shown) is provided inside the side wall 510, and the air supply unit supplies air to the rotating body 540.

11 is a diagram illustrating another example of a disk screen device according to the present disclosure.

11 is a view showing a cross-sectional view BB′ of FIG. 10(b).

It includes an inner space 521 of the shaft 520, and a plurality of holes 522 are formed in the shaft 520. Air may encounter between the plurality of shafts 520 and thus a portion in which air does not move may be generated. Then, while the movement of the light waste T stops, the aggregated light waste T may fall below the disk screen device 500 (see FIG. 10).
