Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulk storage facility for storing bulk materials such as coal.

[0002]

2. Description of the Related Art Conventionally, bulk materials such as coal used as fuel for power generation have been carried out from a transport ship, then loaded on the ground near the power plant, and supplied to the power plant as needed. However, in such landing, there is a problem that coal is deteriorated by being exposed to wind and rain, and dust (coal dust) is scattered.

In order to solve such a problem, FIG. 5 (A)
Provide a circular silo (round silo) as illustrated in
The storage of bulk materials such as coal has become part of the practice. As shown in FIG. 5B, a plurality of the round silos 1 are usually arranged adjacent to each other, and the receiving conveyor 2 is arranged so as to pass through the top center of the plurality of the round silos 1. Bulk materials are dropped inside from the center of the top of the pile 1 to be accumulated inside, and are sent out from the round silo 1 to a power plant or the like by a payout conveyor 3 that passes under the round silos 1. Further, by providing the receiving conveyor 2 and the payout conveyor 3 in parallel with each other, it is possible to simultaneously receive two or more types of bulk materials and simultaneously dispense two or more types of bulk materials.

[0004]

However, since the round silo is a fixed point product in which the bulk material is dropped from the center of the top and accumulated inside, the bulk material silo has a silo as illustrated in FIG. 5 (A). It accumulates in a conical shape inside, creating a large dead space (useless space) at the top of the silo, and because it is round (circular), there is a large dead space around the circle compared to the rectangle, and Even if the mold silos are closely arranged, the space between the silos becomes a dead space, which causes a problem of low storage efficiency of the silos. Further, since the payout facility is located below the silo, there is a problem that the total height of the silo is high, the facility cost is large, and a dead space is also formed in the lower part.

The present invention was devised to solve such problems. That is, an object of the present invention is to provide a bulk material storage facility having a small dead space and a high storage efficiency.

[0006]

According to the present invention, a storage facility (12) having a rectangular cavity (11) having an open upper portion and extending in a horizontal longitudinal direction, and a storage facility (12) which moves substantially horizontally in the longitudinal direction.

It is possible to perform “two types of simultaneous receiving” in which two or more types of bulks are simultaneously received via the receiving conveyors A, B, C and D, and two bulk discharge devices 18 are used to remove the bulks 4 from the two rectangular cavities 11. By carrying out, “two types of simultaneous payout” can be performed via the payout conveyors E, F, G, and H.

FIG. 3 is a sectional view (A) and a sectional view (B) of FIG. As shown in FIG. 1 and FIG. 3, the stowage device 16 includes a transfer conveyor 22 that conveys the bulk material 4 from the tripper device 20 to the center of the opening of the storage facility, and a shuttle disposed below the transfer conveyor 22. A conveyor 24,
Consists of. Further, the tripper device 20 is capable of independently traveling in the longitudinal direction, and is configured to move the bulk material 4 carried in by the receiving conveyor 14 to the storage facility side.

The tripper device 20 includes a pulley 20a for partially raising the endless belt 13 of the receiving conveyor 14 and a bulk material 4 falling from the raised belt 13.
Side chute 20b for transferring the vehicle to the transfer conveyor 22
Have and. The transfer conveyor 22 is the edge 12a of the storage facility.
To the center of the opening of the storage facility.

The shuttle conveyor 24 extends horizontally in the width direction of the storage equipment and can reciprocate in the width direction.
That is, the frame 16a of the stowage device 16 is provided with two rails 16b extending in the width direction, and the wheels 24a of the carriage supporting the shuttle conveyor 24 travel on the rails 16a and can reciprocate in the width direction. It has become. In addition, the endless belt 24b that constitutes the shuttle conveyor 24
Also, it is designed to rotate forward and backward in the width direction.

With the above-described structure, the tripper device 20 moves the bulk material 4 from the receiving conveyor 14 to the opening side of the storage facility, and the transfer conveyor 22 horizontally transports the bulk material 4 to the central portion of the opening of the storage facility. The shuttle conveyor 24 reciprocates in the width direction of the carriage and the shaft conveyor 2
By rotating the shuttle conveyor 24 in the forward and reverse directions, it is possible to deposit the bulk material from the both ends of the shuttle conveyor 24 in the rectangular cavity 11 of the storage facility 12 almost uniformly over the entire surface. Therefore, unlike conventional round silos, bulk material is not deposited in a conical shape inside the silo to create a large dead space above the silo, and storage efficiency can be improved.

In FIGS. 1 and 3, the storage facility 12 is
It has a plurality of horizontal covers 26 spanning the opening in the width direction and divided in the longitudinal direction. The stacking device 16 further includes a cover removing device 28. The cover removing device 28 includes a suction portion 28 that sucks onto the upper surface of the cover 26.
a and a cylinder 28b for vertically moving the suction portion 28a. The attraction unit 28a may be a magnet or a vacuum attraction plate. With such a configuration, as shown in FIG. 2, the suction portion 28a is sucked onto the upper surface of the cover 26 so that the cylinder 2
8b lifts the cover 26, and the adjacent cover 26
The cover 26 can be removed only at a necessary portion of the storage facility 12 by placing it on the above or in an appropriate storage location, and the intrusion of rainwater can be minimized even in the operation such as rainy weather.

FIG. 4 is a view similar to FIG. 1 showing the load unloading device 18. As shown in this figure, the load unloading device 18 is
It is a bucket conveyor type. By the endlessly rotating bucket conveyor 18a of the unloading device 18, the bulk material 4 inside is moved from the upper side of the storage facility to the horizontal conveyor 18b in the unloading device 18, and the unloading conveyor 29a provided below the unloading device 18 is moved. , 29b can be supplied to a power plant or the like. Therefore, it is not necessary to provide the dispensing facility below the storage facility, and it is possible to reduce the height of the entire storage facility and reduce the facility cost. The storage facility 12 is
It may be installed on the ground, or may be installed underground or semi-underground.

Further, this cargo unloading device 18 is
More preferably, it is an L-shaped bucket conveyor unloader as disclosed in No. 24694. As a result, even the loose articles 4 located under the load unloading device 18 and the unloading conveyors 29a, 29b can be easily carried out, and the strength of the opening 11 at the bottom of the edges 12a, 12b of the storage facility 12 is allowed. As wide as possible, the storage efficiency can be further increased.

Further, the lower end frame (not shown) of this cargo unloading device is provided with the above-mentioned cover removing device 28. As a result, the cover 26 can be lifted and placed on the adjacent cover 26 or the like by the cargo unloading device 18 as well, and as shown in FIG. 2, the cover 26 can be removed only at a necessary portion of the storage facility 12. It is possible to minimize the intrusion of rainwater even during rainy weather.
