Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a silo capable of simultaneously performing loading and discharging.

[Conventional technology]

A conventional silo will be described with reference to FIG. 1 showing an embodiment of the present invention. In the center, a ring-shaped disk 2 is provided in multiple stages to provide a disk column 3, and a space between the cylindrical upright side wall 1 and a load (powder or the like) 20 is provided. In the upper part of the storage space, the beam 5 is installed so as to be able to turn horizontally.
The beam 5 is provided with a winch (not shown). In the winch, a screw conveyor 7 is installed via a rope 8 so as to be vertically movable. The screw conveyor 7 is composed of two screw conveyors installed horizontally and in parallel. Ten
Is a conveyor for storage, and 12 is a screw conveyor.
Reference numeral 15 denotes a delivery port, and reference numeral 16 denotes a delivery conveyor.

Describing the case of loading in the storage space, the load supplied from the conveyor 10 is the entrance 11 and the screw conveyor 1
2, is supplied to the screw conveyor 7 through the chute 13. Since the screw conveyor 7 rotates so as to convey the load from the disk column 3 side to the side wall 1 side, the load is conveyed in the same direction. In addition, since the beam 5 is turning horizontally, the load is stacked flat. Beam 1
When rotated, the position of the screw conveyor 7 is slightly elevated. In this way, the position of the screw conveyor 7 is raised and stowed.

Explaining the discharging of the loaded cargo, the screw conveyor 7 is rotated in a direction opposite to the direction in which the cargo is loaded. The load is moved from the side wall 1 side to the disk column 3 side, falls into the disk column 3 between the disks 2 and reaches the conveyor 16. Further, the beam 5 is horizontally turned in a direction opposite to the direction at the time of stacking. The screw conveyor 7 is lowered with the dispensing.

A case in which stowage and payout are performed simultaneously, that is, a case of direct delivery will be described. In this case, the material is supplied to the screw conveyor 7 via the chute 13 as in the case of the stowage. The screw conveyor 7 is rotated in the dispensing direction.

Such a silo is disclosed in JP-A-58-17021.

[Problems to be solved by the invention]

When the loading and unloading are performed simultaneously, that is, in the case of direct feeding, the screw conveyors 1 and 7 need to be operated. That is, in this case, although the operation does not substantially perform the stowage, it is necessary to operate the two screw conveyors 12 and 7, which requires much power cost.

Further, when any of the operation of the screw conveyor 7, the lifting and lowering of the screw conveyor 7, and the operation of the screw conveyor 12 fails, there is a case where it is desired to supply the load to the demand destination. In this case, the upstream end of the conveyor 10 and the downstream end of the conveyor 16 may be connected by a conveyor. That is, it may be sent directly. However, adding this conveyor requires the conveyor and the site.

An object of the present invention is to make it possible to perform direct sending at a low cost with a simple configuration.

[Means for solving the problem]

The present invention provides that a passage communicating the entrance and the upper part of the disk column is provided, and switching means for switching the supply of the load of the entrance to the conveyor installed at the lower part or the supply to the passage is provided. Features.

[Action]

During the loading operation, the passage is closed. At the time of direct delivery, the passage is opened by the switching means. The load at the entrance falls through the passage into the disk column.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. A passage switching means 30 is provided between the screw conveyor 12 and the lower part of the entrance 11. The switching means 30 includes two rotatable dampers 31, 31, and a driving device 32 for rotating the dampers 31. A passage 33 is formed outside the guide case 12a of the screw conveyor 12, and the entrance 10 and the upper part of the disk column 3 are connected. When the two dampers 31, 31 are moved inward, the tips of the dampers 31, 31 come into contact. At this time, the load at the entrance falls through the passage 33 into the disk column 3. When the two dampers 31, 31 are opened, the passage 33 is closed, and the load at the entrance 11 falls onto the screw conveyor 12. On the other hand, the tip 31a of the damper 31 projects inward, and closes the gap at the tip when the two dampers 31, 31 are tilted inward.

Reference numeral 12b denotes a screw, and 12c denotes a driving device for driving the screw 12b. Other configurations are the same as the conventional one.

In such a configuration, a description will be given of a case where the stowage operation is performed. When the dampers 31, 31 are tilted outward, the passage 33 is closed. Other operations are the same as the conventional operation.

When the loading and the discharging are performed at the same time, that is, when the direct feeding is performed, the dampers 31 are closed inward, and the passage to the screw conveyor 12 is closed. In this way, conveyor 1
0, the load passing through the storage opening 11 falls into the disk column 3 through the passage 33 and is supplied to the conveyor 16. The operation of the screw conveyors 12, 7 is unnecessary.

According to this, since the operation of the screw conveyors 12 and 7 is not required, energy can be saved, and the driving operation and the like can be simplified. Further, since the load of the incoming conveyor 10 is supplied to the outgoing conveyor 16, there is no variation in the amount of the load supplied to the outgoing conveyor 16.

By operating the screw conveyor 7 at the same time,
A large amount of cargo can be carried out.

When loading a part of the load supplied by the receiving conveyor 10, open the required amount of the dampers 31, 31, and set the screw conveyor 12,
Drive 7 mag.

If any of the operation of the screw conveyor 7, the elevation of the screw conveyor 7, or the operation of the screw conveyor 12 fails, if direct feeding is required, the dampers 31, 31 are closed as described above, and the direct feeding operation is performed. I do. According to this, no new conveyor is required, it can be inexpensive, and no site is required.

In the embodiment shown in FIG. 3, the bottom surface 12c of the guide case 12a of the screw conveyor 12 is fixed to the guide case 12a by bolts 36.
It is provided detachably. Reference numeral 37 denotes a door for entering the passage 33. The bottom plate 12c is below the storage opening 11.

At the time of direct shipment, open the door 37, remove the bolt 36, and
except for.

This is sufficient if the emergency needs to be sent directly in a few cases.

〔The invention's effect〕

ADVANTAGE OF THE INVENTION According to this invention, in the case of a direct delivery, driving | operation of a conveyer for stowage can be made unnecessary and it can save energy.
