Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an apparatus for breaking the packaging material of municipal waste packed in plastic bags, cardboard boxes, etc. and discharged.

(Prior Art) General municipal waste includes many items that can be recycled, such as empty cans, empty bottles, and other plastic packaging materials for food. Some local governments ask residents to dispose of these items separately on garbage collection days, but in many cases they are packaged in plastic bags or cardboard boxes along with food waste, etc., and the above-mentioned The reality is that even local governments do not make this distinction thoroughly. For this reason, the packaging of the collected rubber is manually torn apart one by one at a processing plant, and the recyclable waste is sorted out.

(Problem to be solved by the invention) However, the breaking of packaging materials at the above-mentioned processing plant is an extremely troublesome and inefficient work that requires manpower, so mechanization of this work is strongly desired. It was rare.

The present invention was developed in view of the above, and aims to improve the efficiency of the above-mentioned work by mechanically breaking the packing materials for urban waste packed in plastic bags, cardboard boxes, etc., and distinguishing it from the waste inside. That is.

(Means for Solving the Problems) The configuration of the present invention for achieving the above object will be explained based on the attached embodiment drawings. FIG. 1 is an overall vertical sectional view showing one embodiment of the breaking device of the present invention, and FIG. 2 is a sectional view taken along the line -- in FIG. That is, the packing waste breaking device of the present invention has a spiral feeding blade 1 on the inner surface.
1 and provided with a plurality of centripetal gourds 12 projecting along the edges of the sending blades 11; A rotating body 2 that rotates on its axis and has centrifugal claws 21 projecting from it, an inlet 3 for the material to be processed provided at one end of the drum 1, and an inlet 3 provided at the other end of the drum 1. It is characterized by comprising a discharge port 4 for the processed material.

(Function) In the device having the above configuration, municipal waste packed in a plastic bag, a cardboard box, or the like is directly input into the input port 3. The input waste is transferred to rotating drum 1.
Due to the rotation of the rotating body 2 and the rotating body 2, the packaging material is broken by the shearing action of the claws 12..., 21... attached to both. A wide variety of miscellaneous waste spilled from the packaging material accumulates in the groove 110 formed between the feed blades 11, and is discharged to the discharge port 4 side together with the fragments of the packaging material under the action of the feed blades 11 as the drum 1 rotates. and is discharged from the discharge port 4. The discharged waste is sorted manually, or iron scraps and the like are automatically sorted using magnets, and are temporarily stored in respective stockyards.

(Example) Next, an example will be described. In FIGS. 1 and 2, the rotating drum 1 is open at both ends,
A pair of front and rear tires 13, 13 are encircled around the circumferential body, and a receiving roller 14 is inserted through the tires 13, 13.
...It is rotatably placed on top in an almost horizontal position.
Further, a gear 15 is further encircled around the circumference of the drum 1, and the drum 1 receives a driving force from a motor (not shown) through the gear 15, and is rotated on the receiving rollers 14. Both ends of the drum 1 are provided with hoods 30, 40.
The hood 30 on the input side is provided with an input port for the material to be processed and an intake port 5, and the input port 3 is connected to an input shutter 31. On the other hand, the lower part of the discharge side hood 40 serves as the discharge port 4, and the upper part thereof is provided with an exhaust port 6, which is connected to a suction blower (not shown). The suction system using the exhaust port 6, the suction port 5, and the suction blower (not shown) exhausts the odor inside the rotating drum 1, and also quickly transports light objects such as broken packaging materials to the discharge side. It is functional and should be adopted. In addition, a plurality of through holes 16 are bored in the middle wall of the rotating drum 1, and furthermore, the drilled portions of the through holes 16 are covered with an intermediate hood 17 having an intermediate discharge port 171 at the bottom thereof. . The through hole 1
6. As a result of the breaking treatment of the packaging material as described above, fine iron scraps, glass scraps, etc. contained in the waste transported in the groove 110 are allowed to pass through and fall from the intermediate discharge port 171. This is intended to be used to distinguish in advance from what is discharged from the discharge port 4 to aid in subsequent sorting, and this is also preferably adopted as described above.

The rotating body 2 is comprised of a cone portion 22 on the input side and a straight portion 23 on the discharge side, and is rotatably mounted within the rotating drum 1 via a rotating shaft 20. The cone portion 22 is preferably adopted because it secures a wide space between it and the inner wall of the rotary drum 1 and allows even large packaging waste to be thrown in smoothly. It is not excluded that the entire rotating body 2 may be straight as long as it has a relatively low bulk. Further, although the rotating body 2 is shown to be a solid body in the illustrated example, it may be hollow, and the cross section is not limited to a circular shape but may also be polygonal. A spiral blade 24 is wound around the circumferential body of the rotating body 2 from the straight portion 23 to the cone portion 22, and the claws 21 are provided on the edge of the spiral blade 2 at intervals. There is. The illustrated example shows an example in which the spiral blade 24 is wound,
Providing claws 21 directly protruding from the circumferential body of the rotating body 2;
Alternatively, it is not excluded that a plurality of disk plates may be spaced apart in the longitudinal direction and the claws 21 may be provided protruding from the peripheral edges of the disk plates. When the spiral blade 24 is wound as shown in the figure, the rotating direction of the rotating body 2 should be set in such a direction that the processed material is pushed out to the discharge side by the spiral blade 24. For example, the spiral blade 24 as shown in the figure should be Regarding the winding mode, see arrow x in Fig. 2.
The direction shown is desirable. As for the direction of rotation of the rotary drum 1, it will be easily understood that the direction indicated by the arrow y in FIG. 2 is appropriate when the feeding blades 11 are disposed as shown in the figure. In this way, the claws 1 attached to each of the rotating drum 1 and the rotating body 2 as they rotate.
The packaging material of the waste thrown in is broken due to the shearing action between 2..., 21..., but the spiral blades 22...
Depending on the arrangement of the sending blades 11, both may rotate in the same direction for the above reason. In this case, by making the rotational speed of the rotating body 2 higher than that of the drum 1, efficient breaking can be ensured.

In the embodiment, an example is shown in which the rotating body 2 is disposed coaxially with the rotating drum 1, but the present invention is not limited to this, and a case in which the rotating body 2 is slightly eccentric downwardly or to the left or right is not excluded. It goes without saying that other changes may be made without departing from the scope of the present invention.

(Effect of the invention) As described above, according to the packaging waste breaking device of the present invention, the waste packed in a plastic bag or a cardboard box, etc., which is inputted from the input port 3, is destroyed by the rotating drum 1 and the rotating drum 1 that rotate with each other. The packaging material is broken by the shearing action of the claws 12..., 21... attached to the rotating body 2, and the waste spilled from the packaging material is transferred to the drum 1.
It is conveyed within the drum 1 by the action of the feeding blades 11 provided on the inner surface of the drum 1, and is discharged from the discharge port 4.
Therefore, if this device is installed before the sorting process in a processing plant, packaging materials can be broken very easily with almost no human effort, and the efficiency of such processing work can be dramatically improved. As described above, although the device of the present invention has a simple structure, the benefits obtained are extremely large.
