Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an apparatus for compressing and solidifying various domestic wastes, industrial wastes, etc., including wood chips, paper, plastics, metal pieces, etc.

(Prior Art) Various household wastes and industrial wastes include various miscellaneous pieces of wood, paper, plastics, metal pieces, and the like. These wastes are incinerated, landfilled, recycled, or the like. In this case, bulky materials are crushed in advance to make them into fine or coarse particles and then subjected to the above-mentioned treatment.

(Problem that the invention aims to solve) By the way, it is natural that waste must be collected, stored, and transported before the above treatment, but if it is left in the state in which it is disposed of, it is extremely dangerous. Because it is bulky, it is difficult to handle and has poor storage and transportation properties. In addition, when disposing in a landfill, the space in the landfill is limited, so it is desirable that the volume be as low as possible. On the other hand, although the bulk of the crushed waste is somewhat reduced, it is not sufficient to eliminate the above problems, and therefore, drastic improvements in the above waste treatment have been desired.

The present invention was developed in view of the above circumstances, and aims to compress and solidify waste at the source to improve workability, storage, transportability, etc. for subsequent processing, and is particularly powerful. The solid material is compressed to increase the volume reduction rate, and the solid material can be easily and efficiently discharged simply by moving the pressurizing plate.

(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 a longitudinal sectional front view showing an example of the device of the present invention, and FIG. 2 is a lateral plan view of the same embodiment. That is, the waste compression solidification apparatus of the present invention includes a waste storage hopper 1, a compression chamber 2 having a supply port 21 and a take-out port 22 communicating with the hopper 1, and a front and rear slider in the compression chamber 2. It is composed of a pair of front and rear pressure plates 3 and 4 that are movably fitted and operate opposite each other toward the compression position, and the top and bottom surfaces of the pressure plates 3 and 4 are provided with upper and lower surfaces along the width direction, respectively. Sharp edge portions 31, 41 and central concave portions 32, 42 are formed so that when they are mated in the compressed position, a cylindrical molding cavity 20 along the width direction is formed between the mating surfaces. In the apparatus for compressing and solidifying waste, the outlet 22 is located on the lower surface of the compression chamber 2 away from the supply port 21 and in front of the compression position, and the outlet 22 is located on the lower surface of the compression chamber 2 that corresponds to the outlet 22. A pair of left and right compression members 5, 5 are arranged on both side walls of the press plate 3, 4 to perform compression work within the cylindrical molding cavity 20 by being reciprocally driven toward and away from the pressure plates 3, 4 in the lateral direction. The pair of pressurizing plates 3 and 4 are characterized in that they are configured to move backward after the compressing members 5 and 5 are compressed above the outlet 22.

The waste to be compressed by the device of the present invention can be any of various household wastes and industrial wastes, including wood chips, paper, plastics, metal pieces, etc. Although it is preferable to use one that is somewhat bulky, it can also be processed. Furthermore, when the compressed and solidified processed material is to be reused, for example, as solid fuel, recycled pulp, recycled plastics, etc., it is desirable that waste be sorted in advance.

(Function) The procedure for processing waste using the compression solidification device will be briefly described. At the start of processing, the pressure plate 3 on the supply side
is located behind the supply port 21 , and the other take-out side pressure plate 4 is set so that its front end surface is located at the front opening edge 211 of the supply port 21 . In this state, waste A is supplied from the hopper 1 into the compression chamber 2 through the supply port 21. Then, the pressure plate 3 starts to move forward, and the waste A is supplied into the compression chamber 2.
is pushed forward and compressed at the compression position in the compression chamber 2, and is brought into contact with the other pressurizing plate 4. At this time,
A cylindrical molding cavity 20 along the width direction is formed by concave portions 32 and 42 on the opposing surfaces of both pressure plates 3 and 4, and the waste A is compressed and solidified within this cavity 20. Further, when the pressurizing plate 3 moves forward, the waste A is densely compressed by the upper and lower edge portions 31, 31 under the action of the centripetal direction without remaining in the compression chamber 2. When the upper edge portion 31 reaches the opening edge portion 211, the waste and large objects protruding upward are cut and separated by the shearing action between the two, and a certain amount of waste is compressed into a columnar shape within the molding cavity 20. be done. Therefore, the pressure plate 3 can smoothly move forward without being subjected to a large load. Thereafter, the pressurizing plates 3 and 4 in this opposed state simultaneously move forward and reach above the outlet 22. Here, the compression members 5, 5 arranged on the left and right actuate, and the columnar compressed waste A in the molding cavity 20 is compressed from its longitudinal direction and further densified. After the compression members 5, 5 are retracted to their original positions, when the pressure plate 3 is retreated, the waste becomes a compressed solidified material B and falls from the outlet 22. By repeating this operation, the compressed solidified material B is sequentially discharged from the outlet 22. In addition, when only paper is compressed and solidified, in order to maintain the shape of the resulting compressed solidified product B, water or other binder is required in the hopper 1 or the compression chamber 2, although it is not shown in the figure. It is desirable to make the input according to the situation.

(Example) Next, an example will be described. In the figure, a table feeder 11 is installed inside the hopper 1,
A chute portion 12 is connected between the discharge port of the table feeder 11 and the supply port 21, and the waste A in the hopper 1 is transferred to the table feeder 1.
1 is sequentially supplied into the compression chamber 2 through the chute section 12 and the supply port 21.

The pressure plates 3 and 4 can be driven back and forth in the compression chamber 2 by hydraulic cylinders 30 and 40, and the stroke of the pressure plate 3 on the supply side is at least equal to that of the supply port 21, as is clear from the above explanation of the operation. It is necessary to reach the upper part of the outlet 22 from the edge (right edge in the figure), and the stroke of the pressure plate 4 on the outlet side is similarly from the upper part of the outlet 22 to the front opening edge 211 of the supply port 21. up to the compressed position is required, but
By changing this stroke appropriately, the amount of waste A supplied into the compression chamber 2 changes, and if the compression force of the compression members 5, 5 is kept constant, it will also be related to the rotation speed of the table feeder 11. outlet 22
Size (length) of compressed solid material B discharged from
can be changed arbitrarily. The concave portions 32 and 42 formed on the tip surfaces of the pressure plates 3 and 4 have a substantially triangular cross section in the illustrated example, and therefore the molding cavity 20 formed by pairing them has a cylindrical shape with a rectangular cross section. However, the present invention is not limited to this, and it is not excluded that the recessed portions 32, 42 may be formed in a circular or other polygonal shape.

In addition, a pair of left and right compression members 5, 5 disposed on both side walls of the compression chamber 2 corresponding to the outlet 22 are reciprocated by hydraulic cylinders 50, 50, and the corners compressed in the molding space 20 are reciprocated by hydraulic cylinders 50, 50. The columnar solidified material is further compressed from its longitudinal direction. The cross-sectional shape of the compression members 5, 5 is similar to that of the columnar molding cavity 2.
It has a shape that can be inserted into 0, and is diamond-shaped in the illustrated example. Moreover, projections 51, 51 are formed on the front end surfaces of the compression members 5, 5, so that the compression of the central portion is made stronger during the above-mentioned compression.

The lower part of the outlet 22 serves as a discharge platform 6 for the solidified product, and a scraper 61 that interlocks with the pressure plate 3 is installed on the discharge platform 6. The scraper 61 operates forward at the same time as the pressure plate 3 moves forward, and functions to successively push the compressed solidified material B falling from the outlet 22 forward.

Reference numeral 7 in the drawing denotes an oil tank, into which operating oil for the hydraulic cylinders 30, 40, and 50 is circulated and supplied. These operating members have heat due to their characteristics, so
A large capacity tank as shown in the figure is preferably used to cool the circulating oil.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and for example, means other than a hydraulic cylinder may be used as the driving means for the pressure plates 3, 4 and the compression member 5.

(Effects of the invention) As described above, the waste compaction and solidification device of the present invention is installed at the waste discharge source and strongly compresses and solidifies the waste from all sides one after another to significantly reduce its bulk. Therefore, the workability when transporting and storing the obtained compressed solidified product is dramatically improved, and space and labor can be effectively saved. In addition, it requires less space to dispose of this waste in a landfill, and if the waste to be treated is sorted in advance, it can be easily recycled as solid fuel, recycled pulp raw material, or recycled plastic raw material. Furthermore, since sharp edges are formed on the tip of the pressurizing plate that compresses the waste, even if the supplied waste is excessive or large, it will not be removed during compression. It is possible to solidify a fixed amount by cutting, and the solid material can be discharged simply by the movement of the pressure plate.The structure of the device is extremely simple, requires less power, and has fewer breakdowns and is easy to maintain. . As described above, the device of the present invention improves the efficiency and labor saving of waste treatment, and furthermore promotes the reuse of waste, and its social value is extremely large.
