Description

[Technical field]

[0001] The present invention relates to an incineration material feeding device for feeding incineration material into an incinerator. [Background technology]

[0002] The inlet for feeding materials to be incinerated into an incinerator is generally provided at the top of the incinerator, but in large incinerators, the inlet is provided at a high position above the ground. In order to feed materials to be incinerated from such an inlet at a high position, a device for feeding materials to be incinerated that is equipped with a bucket lifting device is known (see Patent Document 1 below).

[0003] The bucket lifting device is installed beside the incinerator and lifts and lowers the bucket. When the bucket is at the lowest position of the bucket lifting device, the bucket has materials to be incinerated inside. The bucket lifting device lifts the bucket containing the materials to be incinerated to the inlet of the incinerator, and after the materials are incinerated from the inlet, lowers the bucket to the lowest position.

[0004] This makes it easy to load materials to be incinerated even into an incinerator with an inlet located at a relatively high position. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2004-69250 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, with the above-mentioned conventional incineration material feeding device, especially in the case of a large incinerator, the distance from the lowest position of the bucket lifting device to the feeding port becomes long, and the time it takes for the bucket to lift and lower becomes long. In particular, when it is necessary to feed the incineration material to the incinerator multiple times, the bucket lifting operation is performed multiple times, which is inefficient and the feeding time becomes long. Moreover, since the incineration operation of the incinerator must be stopped while the incineration material is being fed, the operating efficiency of the incinerator also decreases.

[0007] In view of the above, an object of the present invention is to provide an incineration material feeding device capable of efficiently feeding incineration material into an incinerator. [Means for solving the problem]

[0008] In order to achieve this object, the present invention provides an incinerator feeding device that feeds incinerated materials from a feeding position provided in the incinerator, the incinerated materials being provided with a bucket that stores the incinerated materials inside so that they can be freely inserted and removed, a bucket holding device that holds the bucket in a releasable manner, a bucket transport path that allows a plurality of bucket holding devices holding the buckets to rotate endlessly at intervals, a bucket connection section where the bucket holding device of the bucket transport path connects to the bucket and begins holding it, and a bucket connection release section where the bucket holding device of the bucket transport path releases the connection to the bucket, the incinerator feeding position being provided at a predetermined position along the bucket transport path, and the incinerator feeding position being provided with an incinerated material feeding mechanism that removes the incinerated materials from the buckets of the bucket transport path and feeds them into the incinerator.

[0009] The bucket holding device connects the buckets at the bucket connecting section and starts transporting the buckets. In this way, by storing materials to be incinerated in multiple buckets and sequentially supplying each bucket to the bucket connecting section, multiple buckets can be efficiently supplied to the bucket transport path.

[0010] The bucket conveying path is provided with a loading position for the incinerator. When the bucket is conveyed to the loading position by the bucket holding device, the incineration material feeding mechanism feeds the incineration material in the bucket into the incinerator.

[0011] The bucket, which has now been emptied by dumping the materials to be incinerated into the incinerator, is transported by the bucket holding device along the bucket transport path downstream of the incinerator's loading position toward the bucket disconnecting section.

[0012] The bucket connection portion and the bucket disconnection portion may be provided at the same position on the bucket transport path. By providing the bucket connection portion and the bucket disconnection portion at the same position, the bucket transport path can be configured to be relatively short.

[0013] In the present invention, a bucket holding device movement path may be interposed between the bucket connection portion and the bucket connection releasing portion, the bucket holding device being connected to the bucket transport path and used to move the bucket holding device that is not holding the bucket.

[0014] The bucket holding device releases its hold on the bucket at the bucket disconnecting section and moves toward the bucket connecting section without holding the bucket. Meanwhile, the bucket that has been disconnected from the bucket holding device at the bucket disconnecting section is discharged on the bucket discharge path and becomes capable of storing materials to be incinerated inside. During this time, the multiple bucket holding devices that rotate endlessly on the bucket transport path sequentially connect and hold the bucket at the bucket connecting section, feed materials to be incinerated into the incinerator using the materials to be incinerated feeding mechanism, and disconnect the empty bucket at the bucket disconnecting section.

[0015] This allows buckets containing materials to be incinerated to be continuously supplied from the bucket supply path without waiting for the return of empty buckets, making it possible to feed the materials to be incinerated into the incinerator extremely efficiently.

[0016] In addition, in the present invention, the bucket transport path includes an ascending transport path for raising the bucket, a lateral transport path for moving the bucket laterally continuous with the terminal end of the ascending transport path, and a descending transport path for lowering the bucket continuous with the terminal end of the lateral transport path, and the loading position of the incinerator is provided at a predetermined position along the lateral transport path.

[0017] Generally, the loading position of the incinerator is set at the top of the incinerator. Therefore, in the present invention, the bucket conveying path is composed of an ascending conveying path, a lateral conveying path, and a descending conveying path. This allows the lateral conveying path to be set at a height corresponding to the loading position of the incinerated part without reducing the efficiency of the loading work of the incinerator, and allows the smooth loading work of the incinerated material to be performed.

[0018] In addition, the present invention is characterized in that each of the input positions of multiple incinerators is arranged along the bucket transport path, and is equipped with a control device that controls the incineration material input mechanism to selectively input incineration materials from the bucket at each input position.

[0019] According to the present invention, by arranging a plurality of incinerators in parallel along the bucket transport path, the incineration materials can be input by the incineration materials input mechanism at the input position of each incinerator. At this time, the input of the incineration materials to each incinerator can be selectively performed by the control device. That is, for example, while continuously transporting a plurality of buckets, it is possible to input the incineration materials to an incinerator other than the incinerator that is performing incineration. Also, the incinerator to which the incineration materials are input can be selected according to the amount of the incineration materials input inside the incinerator.

[0020] Furthermore, the control device is characterized in that it comprises an incinerator information collection unit that collects information from within each incinerator, a discrimination unit that identifies the materials to be incinerated contained in the bucket, and an incinerator selection unit that selects from among a plurality of incinerators an incinerator to which the materials to be incinerated in the bucket are to be dumped based on the information from within each incinerator collected by the incinerator information collection unit and the materials to be incinerated in the bucket discriminated by the discrimination unit.

[0021] According to this, the control device has an incinerator selection unit that selects an incinerator for incinerating the materials to be incinerated in accordance with the results of the discrimination of the materials to be incinerated in the bucket by the discrimination unit. Therefore, by simply supplying buckets from the bucket supply path, it is possible to eliminate the need to check the materials to be incinerated in each bucket in advance, and it is possible to carry out the work of feeding the materials to be incinerated extremely efficiently.

[Diagram 2] FIG. 4 is an explanatory diagram showing a hanger frame and a bucket. [Diagram 3] FIG. 2 is an explanatory diagram showing a schematic diagram of the state in which materials to be incinerated are placed in the bucket. [Figure 4] FIG. 4 is an explanatory plan view showing a bucket supply path and a bucket discharge path. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] An embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, the incineration material input device of this embodiment is provided with a ring-shaped conveying path 4 that is provided so as to surround a plurality of (three in this embodiment) incinerators 1, 2, 3 arranged in parallel. Each of the incinerators 1, 2, 3 is provided at its upper position with an input section 1a, 2a, 3a such as a hopper for inputting the incineration material.

[0024] The conveying path 4 has an endlessly rotating chain 5 stretched around a number of sprockets 6. Each sprocket 6 is intermittently rotated by a driving source (not shown). Thus, the chain 5 intermittently rotates along the conveying path 4.

[0025] A plurality of hanger frames 7 are supported at predetermined intervals by the endlessly rotating chain 5. Each hanger frame 7 releasably connects and holds a bucket 8, and corresponds to the bucket holding device in the present invention.

[0026] The bucket 8 has an open upper surface and, as shown in FIG. 2, has a bottom plate 8a whose lower surface is closed so as to be freely opened and closed.

[0027] 1 and 2, each hanger frame 7 is suspended from the hanging member 5a of the chain 5 via a pivot 7a so as to be able to swing freely, and the up-down direction is maintained no matter what position the hanger frame 7 is in due to the rotation. As a result, the hanger frame 7 moves intermittently in accordance with the intermittent rotation of the chain 5 along the conveying path 4.

[0028] As shown in Fig. 1, the transport path 4 is composed of a bucket transport path 9 and a hanger frame moving path 10. The bucket transport path 9 is a path along which the bucket 8 is transported by the hanger frame 7, and the hanger frame moving path 10 is a path along which the hanger frame 7 moves when not holding the bucket 8. The hanger frame moving path 10 corresponds to the bucket holding device moving path in this invention.

[0029] The bucket conveying path 9 includes an ascending conveying path 11, a lateral conveying path 12, and a descending conveying path 13. In the ascending conveying path 11, the hanger frame 7 is raised by the chain 5 moving (rotating) upward, thereby raising the bucket 8 held by the hanger frame 7.

[0030] The lateral conveying path 12 moves (rotates) the chain 5 in the lateral direction (approximately horizontal in this embodiment) continuing from the end of the ascending conveying path 11, thereby moving the bucket 8 held by the hanger frame 7 in the lateral direction. The input parts 1a, 2a, 3a of the incinerators 1, 2, 3 are disposed at predetermined intervals along the lateral conveying path 12. The input parts 1a, 2a, 3a correspond to the input positions in the present invention.

[0031] In the downward conveying path 13, the chain 5 moves (rotates) downwardly continuous to the end of the lateral conveying path 12, whereby the hanger frame 7 is lowered, and the bucket 8 held by the hanger frame 7 is lowered.

[0032] The hanger frame moving path 10 moves the hanger frame 7 not holding a bucket from the terminal end (lower end) of the downward conveying path 13 toward the starting end (lower end) of the bucket conveying path 9.

[0033] 1 and 4, a bucket connecting section 14 is provided at the start end of the ascending conveying path 11 of the bucket conveying path 9. At the bucket connecting section 14, the bucket 8 is connected to the hanger frame 7. The bucket 8 is supplied to the bucket connecting section 14 with the material to be incinerated contained therein.

[0034] Buckets 8 containing materials to be incinerated are stocked in the bucket supply path 15 and are sequentially fed toward the bucket connecting section 14. The bucket supply path 15 is extended so that its end is continuous with the beginning of the ascending conveying path 11 of the bucket conveying path 9, and is composed of a conveyor or the like.

[0035] A bucket disconnecting section 16 is provided at the end of the downward conveying path 13 of the bucket conveying path 9. At the bucket disconnecting section 16, the bucket 8 is disconnected from the hanger frame 7. The bucket 8 that has been disconnected from the hanger frame 7 is discharged from the conveying path 4 along a bucket discharge path 17. The bucket discharge path 17 is extended so that its starting end continues to the end of the downward conveying path 13 of the bucket conveying path 9, and is composed of a conveyor or the like.

[0036] As shown in Fig. 1, as described above, the input sections 1a, 2a, and 3a of the incinerators 1, 2, and 3 are arranged along the horizontal conveying path 12. An incineration material input mechanism 18 is provided at a position on the horizontal conveying path 12 corresponding to each of the input sections 1a, 2a, and 3a.

[0037] Each bucket 8 moves sequentially above each of the input sections 1a, 2a, 3a. When the bucket 8 is transported to one of the input sections 1a, 2a, 3a, the bottom plate 8a is opened by the incineration material input mechanism 18, so that the incineration material inside the bucket 8 is input from the input section.

[0038] As shown in FIG. 3, the bucket 8 has the bottom plate lock 8b on one side released and rotates about the bottom plate hinge 8c on the other side as an axis, thereby opening the bottom side and allowing the materials to be incinerated inside to fall out.

[0039] The incineration material feeding mechanism 18 is provided on the transporting track of the bucket 8 and is a mechanism for opening and closing the bottom plate 8a of the bucket 8 which has been transported to any of the feeding sections 1a, 2a, 3a. In this embodiment, although not shown in detail, it is equipped with an unlocking section which releases the bottom plate lock 8b of the bucket 8 and an opening / closing guide section which guides the opening and closing of the bottom plate 8a of the bucket 8.

[0040] In this embodiment, the bottom plate 8a of the bucket 8 is structured to open and close by swinging one side, so the incineration material feeding mechanism 18 of the above configuration is adopted, but the incineration material feeding mechanism of the present invention is not limited to this. For example, although not shown, if the bottom side of the bucket does not open and close, a mechanism that turns the entire bucket upside down may be used.

[0041] The incineration material feeding device configured as described above is equipped with a control device 20, as shown in Fig. 1. The control device 20 is equipped with an incineration information collecting section 21 that is attached to each incinerator 1, 2, 3 and collects internal information of each incinerator 1, 2, 3, and a discrimination section 22 that is attached to the bucket connecting section 14 and discriminates the type of incineration material inside the bucket 8 supplied to the bucket connecting section 14.

[0042] Furthermore, although not shown, the control device 20 has a function of an incinerator selection unit that selects an incinerator to which the material to be incinerated inside the bucket 8 is to be thrown. The incinerator selection unit selects one of the incinerators 1, 2, 3 based on the information inside the incinerators 1, 2, 3 collected by the incinerator information collection unit 21 and the type of material to be incinerated inside the bucket 8 identified by the identification unit 22.

[0043] When a bucket 8 containing materials to be incinerated corresponding to an incinerator is transported above the incinerator's incineration section, the control device 20 activates the incineration material injecting mechanism 18 to inject the materials to be incinerated.

[0044] In addition, the control device 20 can also collect the amount of incinerated material inside each incinerator 1, 2, 3 from the incinerator information collection unit 21, and can also control the bucket 8 to dump the materials to be incinerated into the incinerator 1, 2, 3 that has the least amount of materials to be incinerated.

[0045] As described above, the incineration material feeding device of this embodiment not only allows incineration materials to be fed smoothly from each of the multiple buckets 8 into each of the multiple incinerators 1, 2, and 3 in succession, but also automatically determines which of the incinerators 1, 2, and 3 the incineration materials inside the bucket 8 should be fed into, thereby dramatically improving the work efficiency of feeding the incineration materials.

[0046] In this embodiment, the case where materials to be incinerated are fed into the three incinerators 1, 2, and 3 has been described as an example, but the number of incinerators is not limited to this.

[0047] In addition, in this embodiment, the bucket connection part 14 and the bucket connection releasing part 16 are provided at different positions, but in addition, although not shown, the bucket connection part 14 and the bucket connection releasing part 16 may be provided at the same position. This makes it possible to eliminate the need for the hanger frame moving path 10.

[0048] In addition, the bucket connection part 14 and the bucket connection release part 16 can be switched with each other by reversing the operation. This allows the rotation direction of the conveyor path 4 to be changed between forward and reverse depending on the situation, making it possible to more efficiently input the materials to be incinerated.

[0049] In this embodiment, the bucket conveying path 9 including the ascending conveying path 11, the lateral conveying path 12, and the descending conveying path 13 is used to correspond to an incinerator having an input portion at a relatively high position, but the present invention is not limited to this. For example, although not shown, the conveying path may be rotated horizontally, and the bucket 8 may be conveyed horizontally by the bucket conveying path 9. [Explanation of symbols]
