Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical screw conveyor provided in an unloader device or the like for unloading bulk materials.

This is the first vertical screw conveyor installed at the tip of an unloader device for unloading bulk materials from ships.
Something like the one shown in the figure has been conventionally implemented. That is, in the conventional vertical screw conveyor, the tip of the conveying screw (&) protrudes from the outer cylinder (α), and this protrusion is protected by the cage (1).

When the tip of such a vertical screw conveyor is immersed into a bulk material, the fluidity of the bulk material causes the bulk material to form a cage (
c), and unloading and transport is performed by the rotating transport screw (b).

However, with this method, even if the rotational speed of the conveying screw (b) is increased in an attempt to increase the conveying capacity, the loose objects are blown away by the conveying screw (b), resulting in a significant increase in the conveying capacity. I can't.

The present invention was made to solve the problems of the conventional method, and includes a plurality of cargo intake ports opening in the same rotation direction at equal intervals on the outer circumference at the end of the bulk material handling side of the screw conveyor. and has a disk shape with a load supply port in the center, and is arranged between the load intake port and the load supply port so that loose materials from the load intake port can be sent to the load supply port side during rotation. A load receiving device is provided at the bottom and has a load removal plate capable of sending loose objects in the center toward the outer periphery, and a load supply port of the load receiving device is connected to the load receiving device. The present invention relates to a vertical screw conveyor characterized by:

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 2, a screw conveyor (3) consists of a conveying screw (1) and an outer cylinder (2) surrounding the outer periphery of the screw conveyor (1).
) is provided with a load discharge port (4) connected to a conveyor means of an unloader device (not shown) and a screw drive motor (5) for rotationally driving the conveyance screw (1). In addition, the lower end of the outer cylinder (2) of the screw conveyor (3) is equipped with a loading device (rotatably installed) via a rotation joint (6), and a loading device installed on the outer periphery of the outer cylinder (2). The drive motor (8) rotates the load taking device (power) through the drive rondo (9), drive wheel QO) and large gear aυ. This shows the details of the circular upper and lower side plates (12
1 (a plurality of loading ports 04 opening facing the same direction of rotation) are provided at equal intervals on the outer periphery of the main body of the device, which has an approximately water disk shape as a whole, and A feeding flow path Q having the same curved shape for sending the bulk materials taken in at each of the above-mentioned cargo intake ports αa to the rotation center side! 19 is formed between the upper and lower side plates (12) and (13), and furthermore, a direction change guide part (rising cone) o61 is provided at the center of rotation, and the feed flow is provided in the outer peripheral space of the direction change guide part 06). The passage a9 is made into a connecting opening, and a load supply port αD is provided in the upper plate a2 at the upper part of the outer circumferential space of the direction change guide part αe. Cargo supply port a'7)
is connected to the lower end of the outer cylinder (2) of the screw conveyor (3) via the rotary joint (6), and the upper end of the direction change guide section αe is connected to the shaft (1') of the conveying sled (1).
It is formed to have the same diameter as the shaft (1') and is located close to the lower end of the shaft (1'). The feeding flow path αQ transports loose materials taken in from the cargo intake port α when the cargo intake device (7) is rotated as shown by arrow a8 in Fig. 4. It is configured in a shape that causes an action to send toward the center of the force, and this action causes loose objects to be moved along the outer periphery of the load supply port (I7).
It is now possible to lead to the side.

In addition, a plurality of load removal plates αl having a curved shape bent in the opposite direction to the feeding flow path a9 are provided between the outer periphery and the center of the lower surface of the lower plate α, and When the device (7) is rotated in the direction of arrow QE11 (at the time of load loading), as shown by the arrow in Fig. That's what I do.

The loading device (7) is driven by the loading device drive motor (8).
horizontally rotated in the direction indicated by the arrow in Fig. 5,
The conveying screw (1) is driven by the screw drive motor (5).
) are rotated in the same direction (reverse rotation is also acceptable), place the loading device (7) on top of the bulk material, and the load is lifted by the weight of the loading device (7) and the screw conveyor (3). The taking-in device (7) is buried in the bulk material, or by applying a predetermined pressing force. Then, the loading device (
7), the bulk materials are simultaneously taken in from all the loading ports 04), and the taken in bulk materials are accelerated and sent toward the center by the feeding action of the feeding channel 09, and are fed into the direction change guide section ( 1
It is turned upward at e, and the conveying screw (1) continues as it is.
The cargo is conveyed vertically upward by the cargo discharge port (4) and sent to other conveyor means of the unloader device. Also, at this time, the load removal plate Ql provided on the lower surface of the load taking device (7) is effective because it sends out the loose objects at the bottom of the load taking device (7) toward the load receiving port 04) on the outer periphery. It is possible to take in bulk materials and advance the loading of the load taking device (7).

According to the above, it is possible to continuously take in a large amount of loose materials by rotating the load taking device (7), and the amount taken in can be freely adjusted by adjusting the rotation speed. By being integrated into the conveyor (3), vertical conveyance can be easily and reliably carried out continuously, but the drawback of the screw conveyor (3), which has a problem in stably taking in bulk materials, can be solved, and the screw conveyor ( Loading device (7) corresponding to the transport capacity of 3)
By adjusting the rotation speed of the machine, very effective vertical conveyance of bulk materials is possible.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but if the rotation of the conveyance screw and the load conveyance device can be made the same, it is also possible to directly connect them and drive them to rotate with one drive motor. Of course, various other changes may be made without departing from the gist of the present invention.

According to the above-mentioned vertical screw conveyor of the present invention, the end of the bulk material handling side of the screw conveyor has a disk shape so that the bulk material can be taken in simultaneously and continuously from the plurality of cargo intake ports on the outer periphery. By being equipped with a cargo loading device,
It is possible to effectively take in and transport bulk materials by eliminating the problem of reduced capacity for taking in bulk materials when the screw conveyor is placed vertically. It can produce excellent effects such as being able to take in loose objects without problems even when the burial depth of the taking-in device is small.
