Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powder storage device, that is, a storage device having the function of storing and discharging incoming goods.

Stackers and reclaimers used for open storage and unloading in circular yards are conventionally known.

The present invention has a rotating stacker rotatably supported on a shaft installed at the center of the silo, and a discharging conveyor provided under the bottom for discharging the stored powder and granules to the outside, thereby performing the functions of receiving, storing, and discharging powder particles. The purpose is to provide a body storage device.

The present invention will now be described in detail with reference to embodiments illustrated in the accompanying drawings.

In FIGS. 1 and 2, a pillar 2, which is a columnar shaft, is erected at the center of a silo 1 surrounded by a circular peripheral wall 20. As shown in FIG. In the embodiment, the support column 2 is extended to the roof 3,
The upper end is in contact with the periphery of an opening 21 formed at the center of the roof 5.

The openings 21 in this roof are aligned with the central cavities 22 of the columns 2, and the chutes 5 are arranged in these openings 21 and in the central cavities 22. This chute (or ladder)
Reference numeral 5 is for receiving powder, such as coal, from the incoming conveyor 4 provided above the roof.

The bottom of the chute 5 terminates in the upper part of the column, in which an opening 6 is formed, and surrounding this opening 6, a pivoting hopper 7 is pivotably arranged around the column 2. Immediately below the rotating hopper 7, a stacker 9 consisting of a belt conveyor needle and extending horizontally to the peripheral wall 20 is rotatably mounted as a stacker support 11 of the column 2.

The structure in this vicinity is enlarged and shown in detail in FIGS. 3 and 4. That is, the chute or rudder 5 terminates in a conical chute bottom 23, flanked by five openings 6 as shown in FIG. A rotating topper is provided outside these openings 6, and its chute 8 is located above the belt conveyor 9I of the stacker 9. Stacker 9
is the stacker abutment 1 of the column 2 via the bearings 24 and 241.
It is supported on 1. Therefore, the rotating hopper 7 can be rotated together with the stacker 9.

A reclaimer pedestal 15 is provided at the bottom of the pillar 2 having a tower-like structure, that is, in the vicinity of the hopper bottom surface 25, and the reclaimer 12 is rotatably supported on the reclaimer pedestal 15 via a bearing 26.

The reclaimer 12 extends horizontally from the base of this support 2 to a peripheral wall 20.
◎ As shown in the enlarged cross-sectional view of the main part in FIG.
has an internalized belt conveyor 12 and a trolley 28 on its upper part, which can traverse over the claimer from the peripheral wall 20 to the column 2. The trolley 28 is provided with a harrow 27 and a packet wheel 29 that rotates around the reclaimer.

The pillar 2 side of the reclaimer 12, that is, the belt conveyor 1
A hopper 16 is provided at the end of the hopper 2', and directly below the hopper 16 there is a scraping device 17 disposed circumferentially, which is rotated by a scraping device drive unit 14. As shown in FIG. 6, the scraping device 17 consists of a number of plates fixed to a support frame in a vertical and radial direction. This is to collect the granules and drop them onto the delivery belt conveyor 19 buried under the bottom surface 25 of the silo through a chute for one day. The delivery conveyor 3 further sends out the powder and granules on the belt conveyor 19 to the outside.
It is 0.

Next, the operation of this embodiment will be described.

When storing the incoming goods, the powder and granules are fed from the incoming conveyor 4 to the rotating hopper 7 via the chute 5.

The stacker 9, which acts together with the rotating hopper, receives the powder from the rotating hopper and transports it to the tripper 10.
Here, it is dropped into the silo.◎The dropped powder and granules form a pile as shown by the broken line 31. When the pile reaches a certain limit, the stacker 9 rotates, for example, 4 degrees and stops. Make the next pile at this angular position. Such 4-degree turns are repeated to create a continuous pile, but when the relative angle with the reclaimer reaches, for example, 60 degrees, the above-mentioned operation is stopped at that limit position. This is the arrival cycle.

Then, in the dispensing cycle, the reclaimer 12 is activated. That is, the harrow 27 of the reclaimer 12 is brought into contact with the slope of the pile (which has an angle of repose), and the trolley 28 is caused to travel sideways in this state. The slope of the pile is shaken by the claws of the harrow 27, and the powder particles flow down the slope gently under their own weight, and are collected onto the belt conveyor 121 by the action of the packet wheel 29 attached to the trolley 28. In this process, the powder and granules are blended.

The collected powder is transferred from the belt conveyor 121 to the hopper 1.
6 to a scraping device 17, from where it is dispensed via a chute 18 through a dispensing conveyor 19,20. The rotation of the reclaimer 12 is controlled according to the experience of the powder to be discharged.The present invention is not limited to the illustrated embodiment, and many changes and modifications can be made without departing from the spirit of the present invention. Of course.

For example, although the illustrated cross-sectional shape of the roof is arcuate, it may also be linearly inclined, or the chute 5 may be omitted and the coal may be dropped directly into the rotating hopper 7.
Alternatively, the reclaimer may be of a type that does not include a mixing function section and a scraping device and simply scrapes the powder and granules that have fallen on the bottom of the silo. Further, the granular material to be stored means any granular material such as coal, limestone, and grain.

The present invention has the above-described configuration, and is a powder/granular material storage that can effectively perform the functions of receiving, storing, and discharging powder/granular materials.
