Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor storage facility for bulk material, which stores bulk material indoors.

[0002]

2. Description of the Related Art Grain terminals, coal terminals, power plants, steel mills, etc. are equipped with a bulk storage facility for storing bulk materials such as grains, coal, ores and the like.

This kind of bulk storage facility is provided with a discharging mechanical device for discharging the bulk at the lower part of the storage tank, and to guide the bulk by sliding it directly above the dispensing mechanical device. Most of them have a skeleton structure provided with a hopper (a linear slit-shaped hopper, a cone hopper, etc.).

[0004]

However, if the hopper and the discharging mechanical equipment are provided in the lower portion of the storage tank in this manner, the structure of the skeleton becomes complicated and the cost is increased economically. However, there is a problem that the storage efficiency of the bulk material is poor. In addition, in this type of indoor storage facility for loose goods, passages are provided for maintenance and inspection of hoppers and mechanical equipment for delivery, but the atmosphere in the underground underdrain part where hoppers etc. are Because it ’s bad, disaster prevention,
Special attention needs to be paid to safety and security.

An object of the present invention is to provide an indoor storage facility for bulk material, which has high storage efficiency and high safety.

[0006]

In order to achieve the above object, the present invention forms a storage tank for bulk materials in the shape of a bottomed cylinder with a flat bottom wall and side walls surrounding the flat bottom wall. A slidable roof is provided so that the opening can be opened and closed, and mechanical equipment for loading bulk material is provided outside the storage tank to load bulk material into the storage tank through the opening, and the bulk material is loaded from the storage tank through the opening. It is equipped with mechanical equipment for dispensing bulk materials to dispense.

[0007]

Since there is no mechanical equipment for discharging bulk material or other security equipment in the lower part of the storage tank as in the conventional case, the volume of the storage chamber can be expanded correspondingly and the storage efficiency can be improved. In addition, it becomes possible to inspect the mechanical equipment for loading bulk material and the mechanical equipment for bulk material discharge outside the storage tank, and it is possible to improve safety in maintenance work.

Regarding the loading and unloading of bulk materials, the roof is slid to open the opening, and mechanical equipment for loading bulk materials,
The operation is performed by operating the mechanical equipment for discharging the bulk material, and the storage of the bulk material is performed by sliding the roof and closing the opening.
