Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste plastic storage device for storing waste plastic collected for reuse.

[0002]

2. Description of the Related Art Conventionally, it has been general that industrial waste and waste plastic in municipal solid waste are either landfilled with other waste such as crockery and rubber, or incinerated. Since there is a problem of securing land for landfill and a problem of furnace improvement for incineration, it is considered to recycle waste plastic as fuel by heating and melting it into oil.

At present, a large amount of waste plastic collected for reuse is piled up in the open.

[0004]

The waste plastics collected for reuse include those contaminated with juice, leftover food, fish blood, etc., which is unsanitary and has an odor problem. However, there is a problem that if the waste plastic is piled up in the field, the waste plastic becomes dirty and hinders reuse. Moreover, the collected waste plastics include many bulky ones such as 1m-sized boxes and other large container-shaped ones, which requires a lot of land as a site for loading waste plastics. There was also.

The object of the present invention is to solve the above problems,
It is an object of the present invention to provide a waste plastic storage device that reduces the bulk of waste plastic collected for reuse so that it can be easily processed in the next step, and stores it in a hygienic manner.

[0006]

A waste plastic storage device according to the present invention stores a receiving tank for receiving waste plastic, a horizontal pusher and a vertical pusher for crushing the waste plastic in the receiving tank, and a crushed waste plastic. It is provided with a closed storage tank.

[0007]

According to the waste plastic storage device of the present invention,
The waste plastic collected by the car is put into the receiving tank and then crushed by the horizontal pusher and the vertical pusher, whereby the box and other large containers are crushed and the bulk thereof is reduced. The waste plastic whose volume has become low is stored in a storage tank. Since the storage tank is hermetically sealed, the waste plastic in the storage tank does not become dirty and the odor in the storage tank does not leak out.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show a waste plastic storage device according to the present invention. In the following description, the right side of FIG. 1 is referred to as the front and the left side is referred to as the rear.

The waste plastic storage device is a receiving tank (1) for receiving the waste plastic collected for reuse.
And a horizontal pusher (3) and a vertical pusher (4) for crushing the waste plastic in the receiving tank (1), and a storage tank that is provided in front of the receiving tank (1) and stores the crushed waste plastic. (2) and are provided. The bottom wall of the storage tank (2) is
Lower than the bottom wall of the receiving tank (1), the receiving tank (1)
A partition shutter (5) is provided between the storage tank (2) and the storage tank (2).

The receiving tank (1) is provided at a position lower than the surface of the floor (6) and has an opening upward so that waste plastic collected by a car can be directly put into the receiving tank (1). Receiving tank for waste plastic scattered around when throwing in (1)
It can be easily swept into.

Horizontal pusher (3) and vertical pusher
(4) is a plate-shaped pressing part (18) (20) and shaft part (19) (21)
The horizontal pusher (3) is movable back and forth with the lower end surface of the pressing part (18) in contact with the bottom wall of the receiving tank (1), and the vertical pusher (4) The front end surface of the part (20) is vertically movable while being in contact with the front wall of the receiving tank (1). The pressing surface of each pressing part (18) (20) has a diameter of 2
Hemispherical projections (18a) (20a) of 0 cm or more are provided. These protrusions (18a) and (20a) are for applying a concentrated load to a waste plastic box or container to facilitate the crushing of these. If the protrusions are rod-shaped or pyramid-shaped,
Waste plastic sticks to the pointed tip of the projection and interferes with the next operation, which is not preferable. The protrusion may have a shape other than hemispherical as long as it does not stick to the waste plastic. Each pusher (3) (4) is driven by a motor and can be stopped at a predetermined position.

The shaft portion of the horizontal pusher (3) is provided with a receiving tank (1).
It is slidably fitted into the cylinder chamber (14) extending rearward from the rear wall of the cylinder chamber (14), so that fragments of waste plastic do not enter the cylinder chamber (14). As shown in FIG. 2, a lip cover (15) is provided.

The partition shutter (5) is moved vertically by being guided by a vertical guide (16) for opening and closing the partition shutter. As shown in detail in FIGS. 2 and 3, the pressing force of the horizontal pusher (3) is used. The thickness of the lower part (5a) to be received is thicker than that of the upper part (5b), and also the vertical guide (16)
The lower part of is reinforced by a reinforcing member (17). The partition shutter may of course move to the left and right.

The bottom wall (2a) of the storage tank (2) is high in the center, and has a structure in which the drain flows toward the end of the bottom wall (2a). A gutter (7) for collecting drain is provided around the bottom wall (2a). The collected drainage is discharged from the outlet provided in the front side groove (7) and processed in the drain processing facility (8). Water for washing is supplied to the gutter (7). The inside of the storage tank (2) is equipped with a blower installed above the storage tank (2).
It is sucked by (9) and kept at negative pressure. Blower (9)
A deodorizing device (not shown) is installed in the suction pipe (10) connected to the tank, and the gas inside the storage tank (2) is deodorized and stored in the storage tank.
(2) It is designed to be released to the outside and prevent odors from leaking to the outside. The storage tank (2) is provided with a bucket crane (11) for taking out the waste plastic. Bucket crane
The (11) can be operated through the glass from the crane operation room provided adjacent to the upper part of the storage tank (2). Storage tank
The front wall of (2) is provided with a shutter (12) that opens and closes in conjunction with the bucket crane (11). In the reservoir (2)
Although not shown, a fire detector and a sprinkler are also provided.

According to this waste plastic storage device, the waste plastic collected by the car is first collected in the receiving tank (1).
Can be put inside. Then, with the partition shutter (5) closed, the horizontal pusher (3) is advanced, and the waste plastic is removed from the horizontal pusher (3) and the partition shutter.
(5) It is sandwiched between and and crushed. The horizontal pusher (3)
When the vertical pusher (4) is lowered, it is stopped in an unobtrusive position, then the vertical pusher (4) is lowered, and the waste plastic is put between the vertical pusher (4) and the bottom wall of the receiving tank (1). It is sandwiched and further crushed. As a result, the waste plastic box and other large containers are crushed, and the bulk of the waste plastic is reduced. Then the vertical pusher (4) is raised and the partition shutter (5) is opened. Next, the horizontal pusher (3) is further advanced, and the waste plastic whose volume has become low is dropped and stored in the storage tank (2). Storage (2)
The waste plastic stored inside is thrown into a crusher (13) for further crushing it, and is oiled through the required steps.

[0017]

According to the waste plastic storage device of the present invention, a box or other large container in the waste plastic is crushed to reduce its bulk, and the waste plastic having a reduced bulk is stored in the storage tank. Therefore, it is possible to effectively store and store a large amount of waste plastic collected. In addition, since the waste plastic in the storage tank is not contaminated and the odor in the storage tank does not leak outside, it is hygienic and the working environment is good.
