Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for temporarily storing particulate matter, powder, sludge and the like of a water treatment device, and more particularly to improvement of its discharge mechanism.

[0002]

2. Description of the Related Art After storing the above-mentioned granular materials in a hopper or the like,
As a storage device that discharges from its lower portion to a vehicle, a moving container, or the like, for example, a storage device having a configuration shown in FIG. 12 has been conventionally known.

This storage device comprises a pedestal 1 installed on the ground.
While the hopper 3 is suspended via the link mechanism 2, the weighing device 4 is suspended at the other end of the lever 2a of the link mechanism 2. Therefore, from the supply device 5 to the hopper 3
When the contents such as granules are supplied therein, the contents are once stored in the hopper 3, and the weight of the contents is measured by the weighing device 4 via the link mechanism 2. A discharge device 8 having a pair of lids 7 which are driven by a pair of hydraulic cylinders 6 to open and close by being driven by a pair of hydraulic cylinders 6 is attached to the lower part of the hopper 3. The pair of lids 7 covers the opening formed in the lower part of the hopper 3, and by opening the lid 7, the contents in the hopper 3 are discharged downward from the opening.

[0004]

In the conventional storage device, the pair of lids 7 of the discharging device 8 are attached to the lower part of the hopper 3 as described above. If the lid 7 becomes large, it is driven. The hydraulic cylinder 6 for doing so also needs to be large. Therefore, in order to prevent the discharge device 8 from increasing in size, the opening at the bottom of the hopper 3 cannot be made so large. Therefore, as shown in FIG. 12, the shape of the main body 9 of the hopper 3 from the upper supply device 5 to the lower lid 7 must be a pyramid shape whose cross section becomes gradually smaller from the upper part to the lower part.

However, such a conical hopper 3
In the above, there is a problem that when the lid 7 is opened and the contents are discharged, a so-called bridging phenomenon in which the contents 10 are stagnated in a bridge state near the lower outlet portion as shown in the drawing is likely to occur. The occurrence of this bridging phenomenon is
It is already known that the shape of the lower part of the hopper 3 as well as the internal temperature, the flow characteristics of the particles of the contents, and the like are greatly affected.

Further, even if the bridging phenomenon does not occur, there is a problem in that a part of the content adheres to the wall of the hopper 3 and remains and is not discharged.
Further, a discharge device 8 including a hydraulic cylinder 6 and a lid 7
Has a problem that a large-scale hydraulic system is required, each component is expensive, and the structure is complicated.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a storage device having a simple structure and free from the phenomenon of bridging or residual of contents.
