Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is intended for long-term or incineration of combustible waste such as waste paper, newspapers, cardboard, household waste, plastic containers, dishes, etc. (hereinafter simply “garbage”). The present invention relates to a combustible waste compression packing block that can be temporarily stored.

[0002]

[Prior art]

 Conventionally, garbage is compressed to a high specific gravity with a large compression device having a strong compression capacity, and the compressed block is bound vertically and horizontally with an iron wire or a polypropylene resin band (for example, Japanese Utility Model Publication No. 57-30248). ) And compressed waste blocks formed by this equipment are known, and these compressed waste blocks are dumped in landfills, and there is no land subsidence even after a long period of time, and they are effectively used as high-quality ground.

[0003] In the most common conventional example, refuse discharged from each household is directly transported to a landfill by a refuse transport truck, and after being discharged, the garbage is covered with soil. Some wastes are incinerated as they are in incinerators.

[0004] Furthermore, the problem of dioxin has recently been highlighted in incineration of garbage, and as a countermeasure, it is necessary to keep the incineration temperature of the incineration equipment at a high temperature state. Has been found to be effective. To this end, wide-area local governments have proposed that a large amount of garbage be incinerated in a large-scale incinerator that can operate continuously for 24 hours and maintain a high temperature state continuously. ing. Furthermore, such an incinerator that operates continuously for 24 hours has a concept of generating heat energy using garbage as fuel and supplying it to a centralized heating system, or a concept of supplying hot water to a bath or swimming pool. Proposed. In fact, there is a case in northern Europe where the heat energy of the central heating system in winter is supplied from refuse incinerators.

[0005]

[Problems to be solved by the invention]

 However, large-scale compression packing equipment is effective for compressing combustible waste to a high specific gravity in order to build landfills into solid ground, but it requires high running costs and is slow in operating speed. There was a limit in treating combustible waste. For landfills, it is necessary to compress to a high specific gravity.However, due to circumstances such as renovation of refuse incinerators, household refuse can only be stored for a long period of time or temporarily unavailable. It is not necessary to compress with a conventional large-sized compression packing device.

[0006] In addition, it is difficult to secure landfill sites at present using conventional landfill and incineration methods. Only a small amount of garbage can be carried, and return trucks are empty trucks. Uncertainties in the future may include hazardous substances contained in garbage entering groundwater, and garbage spoiling to produce toxic gases, harming the environment.

In order to concentrate garbage from a wide area into a large incinerator that operates 24 hours a day, it is natural that the garbage should be transported from a wide area local government by a garbage transport truck. As the trucks pass through a large area, there is a problem of odor generated from the garbage, so it is difficult to get the consent of the residents in the area where trucks pass. Furthermore, as in the case of northern Europe mentioned above, there is no problem in supplying heat energy to the centralized heating system using garbage as a fuel in winter, but it is not necessary to operate the centralized heating system. The problem is how to save fuel.

[0008] Therefore, an object of the present invention is to prevent the generation of odor from garbage, to store the garbage for a long time or temporarily, and to use flammable garbage that can be used as fuel for incinerators. To provide a compressed packing block.

[0009]

[Means for Solving the Problems] The feature of the compressed packing block for combustible waste according to the present invention is that the combustible waste is compressed into a cylindrical shape to form a block, and the outer peripheral surface of the cylinder excluding both end surfaces is made of polyethylene as a primary packing member. In addition, the entire outer peripheral surface of the cylindrical block is packed in a sealed state with polyethylene film as a secondary packing member to keep the inside and outside shut off. The degree of compression of the blocked cylindrical shape is such that the primary and secondary packaging members can be easily restored to the normal state by cutting.

[0010]

[Embodiment of the invention]

 The feature of the combustible waste compression packing block W according to the present invention is that, as shown in FIG. 1, the combustible waste G is compressed into a cylindrical shape to form a block, and the outer peripheral surface of the cylinder excluding both end surfaces is made of polyethylene as a primary packing member. And the entire outer peripheral surface of the cylindrical block is sealed with a polyethylene film F as a secondary packing member so that the supply of oxygen is stopped and the leakage of gas inside is also stopped. The degree of compression of the blocked cylindrical shape is such that the primary and secondary packing members can be easily restored to the normal state by cutting off the primary and secondary packing members. belongs to. For this purpose, it is most desirable that the specific gravity of the compressed packing block W be compressed to about 0.25 to 0.35. Therefore, when the compressed packing block W is conveyed to an incinerator and incinerated, the polyethylene net N is used. If a part of the polyethylene film F is cut, the compressed garbage G is easily released from the compressed state, and is easily decomposed and restored to a normal state and easily burned.

Next, an apparatus for compressing and packing the flammable waste G in the compression packing block W will be described with reference to FIGS. 2 to 8. The compression packing apparatus 1 used in the circular packing plant 2 includes a raw garbage G And a discharge unit 4 for receiving and compressing the compressed package 5.

In addition to the drive function and the sealing function at the openings on both sides of the compression chamber 6, the end disks 8, 9 provided so as to maintain the distance C from each other also function as a package lifting device. And serves to hold the compressed package 5 in the lifting step. For said lifting operation, the end disks 8, 9 are each pivotally supported by an arm structure 22 and are provided rotatably in a direction 20 towards the compression chamber 6 and in a direction 21 away from the compression chamber. Said arm structure 22 may consist of two arms 23, 24 connected together by a pivot joint 25. Further, the lift arm structure is given a length D as the length of the arm, and the end disks 8, 9 are moved to the closed position I for packing shown in FIG. 5 and the swing position II shown in FIG. Be movable between Here, the swing position II automatically performs the operation of wrapping the compressed package by the arms 23, 24 and the end disks 8, 9 with a plastic film or similar airtight cover. This is the position to send to the work station.

In order to hold the compressed packages 5 between the end disks 8, 9 during operation of the plant, the end disks 8, 9 are provided with a plurality of axially moving packages fixing means 25A, 26. Is provided. The package fixing means 25A, 26 consist of a plurality of spear-shaped members, each of which extends through the end discs 8, 9 and is driven by a drive disc 280 which can move in the axial direction, and is driven in the axial direction 27. Moving toward the interior of the compression chamber and protruding from the end disc and inserted into the package. In this way, by inserting the packing fixing means 25A, 26 into the packing inside the end disks 8, 9, the packing is sandwiched between the inner surfaces 8B, 9B of the end disks. It can be transported outside.

The drivable disk 280 is driven via a plurality of raceway means 30 received in radial grooves 29 located at the center thereof. The bearing ring means is connected to the spear members of the package fixing means 25A, 26. Therefore, the spear-shaped members of the package fixing means 25A, 26 are moved in the axial direction (27, 28) by driving the hydraulic action driving means 31, such as a hydraulic piston cylinder.

Furthermore, the compression endless mat 3 is shaped by the support of the movable guide frame 33 to form a substantially annular compression chamber 6. The movable guide frame 33 is divided into three parts 34, 35, 36 and is driven by, for example, a hydraulic drive jack (not shown) to open the package opened in the direction of 37, 38. It swings between a position III and a closed position I which is closed in the direction of 39,40. The storage means 41, 42 for the endless mat for compression, preferably roller bearings, are provided along the guide frame 33 and cooperate with the surface 3C on the back side of the surface on the compression chamber 6 side. .

The frame pieces 34 to 36 are formed in an arch shape like a banana, and are rotatably and laterally connected to each other, for example, together with a roll 43 pivotally supported between the frame bearing supports 44 and 45.

Although the function of the present invention is clear from the drawings and the above description, the function of the intended circular packaging plant will be briefly described. During the operation of the apparatus, the wastes are conveyed through a feeder 46 formed between the pre-compression bands 47 moving in the supply direction 48 to form the package 5 such as the wastes into a circular shape. Through the compression chamber 6. After the precompression, the waste is rolled and rolled inside the compression chamber 6, which is sealed laterally with end disks 8, 9. The end disk for compression rotates the endless mat 3 for compression in the driving direction 50. Before the guide frame 33 is reassembled and closed, the driving direction 50 of the endless mat 3 is reversed and rotated by the end disks 8, 9 in the driving direction 51. Here, the end disks 8, 9 are driven by suitable means, for example a hydraulic motor 52 provided on each disk. Waste is rotated until the pressure is at a maximum. Next, the net or the packing yarn 53 is wound around the packing 5 to fix the packing 5 in a compressed state. Here, the compression endless mat 3 for the package is opened, and the completed package 5 is pulled out by the rotatable arms 23 and 24. On the other hand, the compression chamber is closed, and a state in which supply of new waste to the circular packing plant 2 can be started.
