Abstract

PURPOSE:To continuously discharge stored goods in a silo without clogging by covering a discharge opening portion of a flat bottom plate blocking up the lower opening portion of a hopper with a conical structure, and disposing a horizontal rotary arm above the flat bottom plate at a space therebetween. CONSTITUTION:The lower end opening portion circular in section of a hopper portion 2 reducing in sectional area as it is downward is blocked up with a flat bottom plate 3 having a plurality of discharge ports opened. A conical structure 6 for covering the discharge ports 4 is disposed above the flat bottom plate 3 at a space therebetween. Stored goods dropping in a silo are distributed to the right and left by the conical structure 6, temporarily received on the flat bottom plate 3, sweeped down from the flat bottom plate 3 through the discharge port 4 by rotation of a horizontal rotary arm 7 disposed above the flat bottom plate 3 at a space therebetween, and dropped on a belt conveyer 9 through a chute 10 to be discharged.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a storage silo for coal, coke, etc.

(Prior Art) Conventionally, in this type of storage silo, discharging is performed directly from the lower end opening of a hopper provided at the lower end of the silo using a dispensing feeder or the like.

(Problems to be Solved by the Invention) However, in the conventional storage silo, the weight of the stored material in the silo is directly applied to the dispensing feeder, etc., so the dispensing machine becomes larger, and accordingly, the power becomes large. There were five problems in that clogging easily occurred inside the storage silo.

(Means for Solving the Problems) The present invention was proposed to solve these problems, and the present invention is to seal the lower end opening of the hopper provided at the lower end of the silo with a flat bottom plate having a dispensing opening. A chevron-shaped structure is disposed within the same hole to cover the upper part of the dispensing opening of the flat-bottomed plate, and a device for dispensing stored materials in the silo is disposed below the flat-bottomed plate, This relates to a storage silo characterized in that a horizontal rotary arm is disposed at an upper portion thereof at a distance and sweeps the stored material in the silo on the flat bottom plate through the dispensing opening and into the dispensing device. .

(Function) Since the present invention is configured as described in 5 above, the stored material in the silo is placed in the hopper provided at the lower end of the silo, and The liquid is sorted and falls by the chevron-shaped structure that covers the upper part of the dispensing opening of the bottom plate, and is once caught on the flat-bottomed plate without flowing down uncontrollably through the opening of the flat-bottomed plate.

The stored materials once received on the flat-bottomed plate are moved from the dispensing opening of the flat-bottomed plate to the silo by the rotation of the horizontal rotary arm disposed above the flat-bottomed plate at a distance from the stored items. The stored items are swept into a dispensing device and discharged from the same dispensing device.

(Effects of the Invention) According to the present invention, as described above, the stored material in the silo is once received on the flat bottom plate that closes the lower end opening of the hopper, and the stored material on the flat bottom plate is discharged by the rotation of the horizontal rotating arm. The stored material in the silo is quantitatively swept through the opening to a dispensing device disposed below, and the stored material is discharged by the dispensing device, and the stored material in the silo is disposed of through a flat surface that closes the opening at the lower end of the hopper. Since the material is supplied to the dispensing device through the dispensing opening in the bottom plate without causing clogging, it is possible to continuously dispense the stored materials in the silo.

Furthermore, according to the present invention, the stored material in the silo is discharged only by horizontal rotation of the horizontal rotating arm, so the mechanism is extremely simple, and the horizontal rotating arm only moves the stored material on the hopper flat bottom plate in the horizontal direction. is sufficient, and less power is required from the electric motor.

Furthermore, since the dispensing device can be manufactured in a factory in combination with a silo and transported to the site, the construction period can be shortened and costs can be reduced.

(Example) The present invention will be described below with reference to the illustrated embodiments.

(1) is a cylindrical silo main body, (2) is a hopper part that is connected to the lower end of the main body (1) and gradually changes into a circular shape with a smaller cross-sectional area as it goes downward; The cross-sectional opening is closed by a flat-bottomed plate (3), and several dispensing ports (4) are opened in the flat-bottomed plate (3).

In the figure, (5) is the support of the silo body (1).

A chevron-shaped structure (6) that is spaced apart from the top of the flat-bottomed plate (3) and covers the dispensing port (4) is provided on the top of the flat-bottomed plate (3).
), and is arranged so that the stored material in the silo does not fall directly through the outlet (4) in an uncontrolled manner.

Additionally, on the flat bottom plate (3), several arm pieces with a concave planar shape are radially branched out, oriented in the direction of forward motion due to rotation, at a distance from the horizontal rotating arm (sword). It is configured to be rotated horizontally via a vertical rotation shaft by an electric motor (8), which is installed in an angle-shaped structure (6) and is optionally combined with a reduction gear. It is configured to sweep the stored material on the bottom plate (3) through the dispensing port (4).

A dispensing device such as a belt conveyor (9) is disposed directly below the flat bottom plate (3), and a shoe is provided at the dispensing opening (4) to ensure that the stored items fall onto the belt conveyor (9). Ql is arranged.

Note that a maintenance/inspection entrance/exit aυ is provided on the side surface of the hopper (2) to facilitate maintenance/inspection.

Since the illustrated embodiment is configured as described above, the stored items falling inside the silo are distributed to the left and right by the chevron-shaped structure (6), are once received on the flat bottom plate (3), and are then received by the electric motor ( 8) (Therefore, the horizontal rotating arm (7)
) from the flat-bottomed plate (3) through the outlet (4), falls onto the belt conveyor (9) via the chute (11), and is discharged by the conveyor (9).

Therefore, the stored materials in the silo are always stored in the outlet (4) of the flat bottom plate (3).
) is supplied onto the belt conveyor (9) in a fixed amount, making it possible to continuously dispense stored agricultural products.

According to the illustrated embodiment, it is possible to continuously dispense stored items in the storage silo, and the mechanism is significantly simplified since the stored items are removed only by the rotation of the horizontal rotating arm (force). Also, since the horizontal rotating arm (force) is sufficient to move the stored items on the flat bottom plate (3) in the horizontal direction, the power of the electric motor can be reduced.

Furthermore, by combining a dispensing device such as a belt conveyor (9) with a silo,
Construction time is shortened and costs are saved.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
