イロに関する。Detailed Description of the Invention The present invention is an underground or semi-underground silo for storing a large amount of coal (including coal, iron ore, and other granular materials, hereinafter collectively referred to as coal), and is a first-in first-out coal silo. This invention relates to a coal storage silo that can be easily handled.

従来、石炭等を貯蔵するサイロは、地上に高
い槽として建設されるのが通例であつた（例え
ば実開昭54―146576号）。Conventional Technology In the past, silos for storing coal, etc. were usually constructed as tanks high above the ground (for example, Utility Model Application Publication No. 146576/1983).
一部に、地下に深く掘つた地下式又は半地下

がかかり、高価につく欠点がある。Problems to be Solved by the Present Invention () The above-mentioned silo constructed as a tank high above the ground has the advantage that coal, etc. can be put in and taken out first, and therefore there is no permanent storage of coal, etc. However, due to its structure, the capacity of the silo could not be made very large, and its storage capacity was limited, making it unsuitable for large-scale coal storage. Furthermore, since this silo is a facility high above the ground, it is time-consuming and expensive to construct.

品質が劣化するばかりでなく自然発火の原因と
なり易い。() On the other hand, silos constructed underground or semi-underground can be easily constructed with a fairly large capacity due to their structure, and are advantageous for storing large amounts of coal. However, when handling the loading and unloading of coal, it is necessary to input it from above the silo and take it out from above.
That is, since it is not possible to handle the coal in a first-in or first-out manner, there is a drawback that coal is likely to be permanently stored. Incidentally, permanently stored coal not only deteriorates in quality but also tends to cause spontaneous combustion.
従つて、従来の地下式又は半地下式サイロは、

搬入、搬出は行なえないので、サイロの運用効率
が甚だしく悪いという欠点があつた。 Therefore, conventional underground or semi-underground silos are
Normally, new coal is not brought in until the tank has been emptied. In other words, since coal could not be brought in and taken out at the same time, the silo's operational efficiency was extremely poor.

It is about providing silos.

As shown in the example shown in FIG. 3, the cylindrical outer circumferential wall 1a of the silo was formed below the ground to a desired depth to configure it as an underground or semi-underground type. Further, the bottom plate portion 1b was inclined at an angle θ greater than the angle of repose of the coal. A plurality of supports 1c are provided upward from the deepest part of the bottom plate 1b with a cylindrical caisson 3 having a height reaching at least the coal lateral unloading device 7, and are connected to the cylindrical outer peripheral wall 1a of the silo. It was supported and installed by... Inside the hollow part of this caisson 3, a coal transport device 5 such as a screw conveyor was installed to transport the stored coal upward. Furthermore, between the lower end of the caisson 3 and the bottom plate 1b, there is a gap h that allows the storage coal to be taken in, which serves as a coal takeout port, and also breaks the arching of the stored coal to encourage its movement (collapse). A device 4 for stirring or shaking was installed.
