Description

[0001] The present invention relates to a silo containing a discharge device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silo including a dispensing apparatus, and more particularly to a silo including a dispensing apparatus in which a load concentrated on a motor can be uniformly distributed.

BACKGROUND ART Conventionally, a silo for storing powdered materials such as coal, coke, and limestone includes a storage silo for storing a powdered material, and a shute for moving the powdered material in a downward direction is provided at a lower portion of the storage silo And includes a cone portion inside the shute.

At this time, a certain region of the chute includes a groove portion, and the cone portion is provided with a dispensing device so that the powdered material is placed under the shute through the groove portion by the dispensing device It is discharged to the belt conveyor.

In addition, the powdered material discharged to the belt conveyor is conveyed to a predetermined place outside the storage silo by the belt conveyor.

At this time, the dispensing apparatus includes a blade curved in an arcuate shape which rotates in a horizontal plane, the blade scraping the storage located in the chute, discharging the scraped storage toward the groove , The stored matter discharged to the groove portion is discharged onto the belt conveyor.

At this time, the dispenser can move along the cone portion, and such a moving dispenser dispenses the stored product while moving inside the storage silo, so that a large storage difference (uneven height) is generated in the storage in the storage silo .

1 is a schematic view for describing a silo including a dispensing apparatus according to the prior art.

Referring to FIG. 1, a silo including a dispensing apparatus according to the related art includes a storage silo 1, and a plurality of chutes 7, (2).

The storage silo 1 includes a shute 7 for moving the storage material in a downward direction and a cone portion 7 is provided in the shute 7, 2).

In this case, as described above, a certain area of the chute 7 includes a groove 3 for taking out the stored material located in the storage silo. When the stored material is discharged to the groove 3, And a discharging device 4 for discharging the liquid.

At this time, the dispenser 4 is coupled with the cone portion 2 and travels along the groove portion 3, and the powdery material, that is, the storage material 6).

On the other hand, as described above, the conventional dispensing apparatus includes a blade curved in an arcuate shape that rotates in a horizontal plane, and scrapes the storage located in the chute by the blade, To the groove portion.

When the driving direction of the dispenser and the moving direction of the blades are in the same direction as each other, the load applied to the blades is set to be greater than the load applied to the blades There is a problem that it becomes very large.

2 is a schematic view for explaining a running direction of a dispenser and a moving direction in accordance with rotation of the blades.

Referring to FIG. 2, the blade portion 10 of the dispenser may include a first blade 11a and a second blade 11b disposed to face the first blade 11a.

At this time, as shown in FIG. 2, it is assumed that the dispenser is traveling in the X direction of FIG. 2, and that the blade unit 10 rotates clockwise as shown in FIG.

In this case, that is, when the dispenser travels in the X direction and the blade portion rotates in the clockwise direction, the moving direction corresponding to the rotation of the first blade 11a corresponds to Y1, and the second blade 11b ) Corresponds to Y2.

That is, in the moving direction Y1, it corresponds to the same direction as the running direction of the dispenser, and in the moving direction Y2 corresponds to the direction opposite to the running direction of the dispenser.

At this time, since a load corresponding to the traveling direction of the dispenser in the moving direction Y1 is further received, the load applied to the blade, that is, the first blade 11a becomes much larger than in the moving direction Y2.

Of course, in the case where the first blade 11a moves in the direction of the second blade 11b and the second blade 11b moves in the direction of the first blade 11a, , The load applied to the second blade 11b becomes very large.

As a result, in the conventional dispensing apparatus of the type using the blades, the loads applied to the regions where the blades are located differ from each other, so that the load concentrated on the motor for rotating the blade portion is also biased to either side , The efficiency of the motor is deteriorated.

In addition, when the load concentrated on the motor is deviated to either side, it leads to failure of the motor and shortening of the life of the motor.

Further, as described above, in the dispenser of the type using a conventional blade, the storage material located in the chute is scraped off by the blade, and the scraped storage material is discharged toward the groove portion.

At this time, the chute may have a region in which the stored product exists, while the stored product may not exist in the chute.

That is, since the blade rotates and scrapes the stored material and discharges it to the groove, there is no storage material to be scratched in a region where the stored material does not exist, so that the storage material can not be scraped by the blade.

Therefore, due to the interval in which the storage material can not be scraped by the blade, the continuity of the stored material dispensed to the groove portion is lowered. As a result, the discharge device of the type using the conventional blades has a problem .

Since this is a general matter, a detailed description will be omitted below.

As described above, in a general blade-type dispensing apparatus, the loads applied to the areas where the blades are placed are different from each other, and the load concentrated on the motor for rotating the blade is also biased to one side, There is a problem that the efficiency of the motor is deteriorated. In addition, a deviation of the load concentrated on the motor leads to failure of the motor and shortening of the life of the motor.

However, in the present invention, the screw type, that is, the first screw part 241 located in the first chute part 221 and the second screw part 242 located in the second chute part 222, The load concentrated on the motor due to the blades can be prevented from being biased to one side by replacing the blades in the common discharge device.

More specifically, in a general blade-type dispensing apparatus, by rotating the first blade and the second blade, the stored material placed on the chute is scraped off and the scraped storage material is discharged toward the groove.

5, by rotating the first driving shaft 241a of the first screw portion 241, the stored substance located on the first plate surface 221b is rotated by the first driving shaft 241a, And can be discharged along the screw 241b toward the groove portion 223 (direction A).

By rotating the second driving shaft 242a of the second screw portion 242, the stored matter located on the second plate surface 222b is moved along the second screw 242b to the groove portion 223, (Direction B).

Since the first screw 241b and the second screw 242b are arranged symmetrically with respect to the driver unit 230, the first drive shaft 241a and the second drive shaft 242a The storage moves in the A direction in the first chute portion 221 and the storage moves in the B direction in the second chute portion 222. In this case, . ≪ / RTI >

In the present invention, even if the dispenser travels in a predetermined direction, since the loads applied to the first screw portion 241 and the second screw portion 242 are equally applied, the first screw portion 241 And the load concentrated on the motor for rotating the second screw part 242 are uniformly distributed.

Therefore, in the present invention, by replacing a general blade type dispensing apparatus with a screw type dispensing apparatus, it is possible to prevent the deviation of the load concentrated on the motor to one side, thereby improving the efficiency of the motor and shortening the life of the motor .

In addition, as described above, in the conventional dispenser of the type using a blade, since the blade rotates to scrape the stored product and discharge it to the groove, there is no product to be scraped off in the area where the product is not present , There arises a section where the storage material can not be scraped off by the blade, so that it is difficult to continuously discharge the storage material.

However, in the screw dispenser of the present invention, since the stored product moves along the screw and is discharged to the groove, a uniform amount of the stored product moving along the above-mentioned skew flows, Not only the burning out is possible but also the amount of the stock which is discharged to the above-mentioned conveyor can be uniformly discharged through the groove portion.
