Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontally rotatable wheel connected to a driving device on a bottom plate located below a bulk storage tank, and rotating the wheel to form the bottom plate. The present invention relates to a rotary bulk discharging apparatus for discharging bulk materials in a storage tank onto a conveyor disposed below a bottom plate through a slit-shaped discharging port.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a horizontally rotatable wheel 5 is placed on a bottom plate 11 of a storage tank 1 in which bulk materials 2 such as coal, slag, iron ore, etc. are stored.
Is installed, and by rotating the wheel 5, the loose objects 2 in the storage tank 1 are discharged onto the conveyor 7 arranged below the bottom plate 11 through the slit-shaped discharge port 10 formed in the bottom plate 11. 2. Description of the Related Art Rotary bulk dispensing devices for dispensing are known, and are widely used, for example, in ships and steelworks.

As shown in FIG. 4, for example, storage tanks 1a and 1b on which different kinds of bulk materials 2a and 2b are loaded are arranged side by side, and a tunnel 30 is communicated with a lower portion of the storage tanks 1a and 1b. Each of the blades 51 forming the wheel 5 in the case where the wheel 5 is installed on the bottom plate 11 located along the bottom of the tunnel 30 so as to be able to rotate horizontally and run in a parallel direction. The bulk material 2a in the storage tank 1a that has been paid out is deposited on the upper surface 52 of the container, and the deposited bulk material 2a is deposited.
However, it may be shaken off in the storage tank 1b where the payout operation is performed next, and may be mixed with the loose objects 2b in the storage tank 1b.

[0004] If the loose material 2a deposited on the upper surface 52 of the blade 51 is left for a long time, the loose material 2a sticks to the blade 51, and the blade 51 is rusted or adhered to the loose material 2a. In some cases, the load for rotation was increased, and the operating efficiency of the wheel 5 was reduced.

[0005] In order to prevent such a situation, conventionally, the blade 51 has been manually cleaned to remove the loose material 2 a deposited on the upper surface 52. However, cleaning work in a narrow place such as the tunnel 30 is extremely inefficient, and requires a great deal of labor and time. In addition, every time one storage tank is dispensed, cleaning must be manually performed, resulting in extremely low work efficiency.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a rotary bulk dispensing apparatus in which the bulk dispensing operation of a storage tank storing different types of bulk is continuously performed by the same wheel. If you do this, loose material from the storage tank that has been dispensed accumulates on the upper surface of the blade of the wheel and mixes with the next loose material in the storage tank to be dispensed, or if the accumulated loose material is left Conventionally, the blade is manually cleaned because the blade sticks to the blade and deforms the blade or deteriorates the operation efficiency. However, it is extremely inefficient.

[0007]

Therefore, in the present invention, a scraper whose tip is in contact with the entire upper surface of the blade of the wheel is fixed to the lower part of the dispensing machine main body in which the driving device is installed.

[0008] During the dispensing operation, when the wheel rotates and the blade of the wheel passes below the scraper, the tip of the scraper sweeps out and removes loose materials deposited on the upper surface of the blade.

Therefore, since the upper surface of the blade can be cleaned at the same time as the dispensing operation, even if the blade is not cleaned by human power, different kinds of loose materials deposited on the blade are not mixed.

[0010] When the scraper is installed so as to be located above the payout port, the bulk material swept out by the scraper is directly delivered to the conveyor.

[0011]

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

As shown in FIG. 4, storage tanks 1a and 1b storing different kinds of bulk materials 2a and 2b are arranged side by side. A rotatable wheel 5 is installed.

As shown in FIG. 1, a payout opening 10 extends continuously in a slit-like shape at the center of the bottom plate 11 in the longitudinal direction at the lower part of the storage tank 1 storing the bulky materials 2. Further, below the bottom plate 11, a conveyor 7 for receiving the loose materials 2 paid out from the payout port 10 and transporting the same to a predetermined place is provided.

On the bottom plate 11, a tunnel 30 surrounded by a cover 3 having a mountain-like top is continuous in the longitudinal direction. This is because the cover 3 covers the upper portion of the payout port 10 so that the bulk 2 in the storage tank 1 does not flow out of the payout port 10 naturally.

In the inside of the tunnel 30, the dispensing machine main body 4 is connected to wheels 42 sliding on rails 31 which are continuously installed in the bottom of the cover 3 in the direction parallel to the storage tank 1 in the parallel direction. The dispensing machine body 4 includes a driving device 6
Is installed. Further, by connecting the wheel 5 to the tip of a shaft 41 extending vertically from the drive device 6, the wheel 5 is installed so as to be able to travel in the parallel direction.

In the wheel 5, a plurality of blades 51 are arranged at equal angular intervals with respect to a center support plate 53 connected to the shaft portion 41, and are arranged spirally in the planar direction in the same direction. It is installed at a position where an appropriate gap is provided above the bottom plate 11.

When the wheels 42 connected to the drive unit 6 slide on the rails 31, the wheels 5 can reciprocate in the direction parallel to the storage tank 1. Preferably, the rotation and running of the wheel 5 can be controlled independently of each other,
While the wheel 5 is moving along the payout port 10 or in a stationary state, the wheel 5 rotates horizontally along the bottom plate 11 around the shaft portion 41 to remove the bulk 2 in the storage tank 1 from the payout port 10 to the bottom plate 11. It is dropped on the conveyor 7 installed below.

Further, a pair of scrapers 8, 8 made of a material having appropriate rigidity and flexibility, such as hard rubber, are provided at the lower portion of the dispensing machine main body 4 as shown in FIGS. The mounting plates 81, 8 are opposed to each other with the shaft 41 therebetween.
1, and is attached by an attachment screw 82. As shown in FIG. 2, the scraper 8 is attached such that the side direction is exactly along the inclination of the upper surface 52 of one blade 51 of the wheel 5 and the tip lightly contacts the upper surface 52. As shown in FIG. 3, the plane direction has a length equal to or slightly larger than the length of the blade 51 so that the blade 51 can contact over the entire length when the blade 51 passes. Further, the scrapers 8, 8 are installed so as to extend in a direction along the longitudinal direction of the payout port 10, and to be entirely located above the payout port 10.

The scraper 8 is attached to the dispenser main body 4 without being directly connected to the driving device 6, so that the scraper 8 is synchronized with the running of the wheels 5 in the parallel direction, but does not rotate. Therefore, when the wheel 5 rotates and the blade 51 passes under the scraper 8, the tip of the scraper 8 contacts the upper surface 52 of each blade 51,
The loose material 2 deposited on the upper surface 52 of the blade 51 is swept away. At this time, since the scraper 8 is attached to the upper part of the payout port 10, the scraps 2 that have been swept down are discharged onto the conveyor 7 as they are.

By rotating the wheel 5 in this manner, the loose materials 2 deposited on the upper surface 52 of the blade 51 can be cleaned simultaneously with the dispensing operation, so that different types of loose materials can be continuously dispensed. However, there is no need to worry that the previously dispensed bulk material would be mixed in the dispensing storage tank.

In this embodiment, the storage tanks 1a and 1b storing different types of bulk materials 2a and 2b are stored.
1b is described as being in parallel, but the present invention can be similarly applied to a case where one type of storage tank is used to successively pay out different types of bulk goods after discharging a certain bulk material. it can.

The blade 51 such as the support plate 53 of the wheel 5
When the scraper 8 has a portion other than the upper surface 52 on which the bulk material 2 is deposited, the scraper 8 is shaped and installed so as to contact the upper surface of the portion together with the blade 51.

Further, in the above-described embodiment, the pair of scrapers 8, 8 are provided at opposing positions with the shaft portion 41 interposed therebetween. It does not matter.

[0024]

According to the present invention, when the wheel passes through the lower portion of the scraper while rotating, the loose material deposited on the upper surface of the blade of the wheel is swept out by the scraper, so that the scrap is automatically automatically discharged. The blade can be cleaned.
Therefore, even when the bulk materials in the storage tanks storing different types of bulk materials are successively paid out, other types of bulk materials are not mixed.

Therefore, it is not necessary to manually clean the blade, and the time and labor are greatly reduced and the efficiency is improved.

Also, since the loose material does not stick to the blade, the blade does not rust and the blade does not deform due to the adhesion resistance of the loose material, and the durability of the blade is improved.

In addition, since the load applied to the blades does not increase due to the accumulated loose objects, the operation efficiency of the wheel does not deteriorate, so that the power can be used efficiently.

Furthermore, when the scraper is installed above the dispensing opening, the loose materials deposited on the upper surface of the wheel blade are swept out and dropped on the conveyor, so that all the loose materials in the storage tank are removed without waste. Can be put out.
