Description

[Detailed description of the invention] This invention relates to a coal discharge device for a coal bin.

Normally, when discharging coal from the bottom opening of a hopper-shaped coal storage tank, there is no problem when discharging coal continuously, but when discharging coal intermittently, a bridging phenomenon occurs and the dispensing becomes difficult. becomes.

Therefore, the present invention forms a first discharge port in a circular bottom plate at the lower end of a hopper-shaped coal storage tank, and provides a dispensing body located below the coal storage tank and having a partition plate parallel to the bottom plate for supplying coal to a coal discharging device. It is rotatably supported on the hopper and on the same axis as the bottom plate, a second discharge port corresponding to the first discharge port is formed in the partition plate, and an upper part of the bottom plate is formed in the center of the partition plate. A shaft inserted therethrough and located in the coal storage tank is fixed, and a guide vane for guiding the coal to the first discharge port is attached above the bottom plate of the shaft, and a guide vane is attached to the upper part of the shaft. An injection nozzle for ejecting compressed gas is provided, and a compressed air supply pipe for supplying compressed gas to the injection nozzle is connected to the lower part of the shaft body through a rotary joint. Coal can be reliably discharged from the coal storage tank even when

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is a hopper-shaped coal storage tank,
The lower end circular bottom plate (hereinafter simply referred to as the bottom plate) 2 is provided with two sector-shaped first coal discharge ports 3 at symmetrical positions with respect to each other. Reference numeral 4 denotes a dispensing body located below the coal storage tank 1 and having a partition plate 5 parallel to the bottom plate 2.
It is rotatably supported on the same axis as the That is,
The dispensing body 4 is supported by the upper end of the supply hopper 7 via wheels 9 attached to a plurality of locations on the outer circumference of the outer cylinder 8. Further, the dispensing body 4 is configured to be rotated in a predetermined direction A. That is, an external gear body 10 is attached to the outer periphery of the outer cylinder 8, and a drive gear 14 is attached to the output shaft of a rotary drive device 13 via first and second gears 11 and 12. is linked to. The partition plate 5 has
Two fan-shaped second discharge ports 15 corresponding to the first discharge ports 3 are provided at symmetrical positions, and in the center of the partition plate 5, the upper part passes through the bottom plate 2 and is inserted into the coal storage tank 1. A positioned and spire-shaped shaft 16 is fixed. In addition, 17 is the shaft body 16 and the bottom plate 2.
This is the seal part interposed between the Above shaft body 1
Coal is placed above the bottom plate 2 of No. 6 and on the lower side of the rotational direction A of the second discharge port 15, respectively.
A guide vane 18 is attached to guide the discharge port 3. Furthermore, a plurality of injection nozzles 19 for ejecting compressed gas (for example, compressed air, inard gas, etc.) are bored in the upper part of the shaft 16, and these injection nozzles 19 are provided at the center of the shaft 16 and in the direction of the shaft. Compressed gas a is supplied through a hole 20 drilled in the center direction and a rotary joint 21 attached to the lower end of the hole 20.
A supply pipe 22 is connected thereto.

Therefore, in the above configuration, when discharging the coal b in the coal storage tank 1 to the coal discharging device 6, the rotation drive device 13 is operated to rotate the dispensing body 4 in the direction of arrow A. Then, the guide vane 18 rotates in the direction of arrow A and guides the coal b above the partition plate 6 to the first discharge port 3, and as a result, the first discharge port 3 and the second discharge port 15 are connected. The coal b is overlapped with each other, and is discharged into the supply hopper 7 through the first and second discharge ports 3 and 15, and the coal b is discharged from the screw 6a of the coal discharge device 6.
It is carried out to a predetermined location by. If a bridging phenomenon occurs during coal discharging, the bridging can be easily broken by spouting compressed gas a from the injection nozzle 19 at the top of the shaft 16.

As described above, according to the coal dispensing device for a coal storage tank of the present invention, the coal in the coal storage tank can be discharged not only continuously but also intermittently.
Furthermore, even if a bridging phenomenon occurs during coal discharging, the bridging can be broken and the coal can be reliably delivered to the coal discharging device.
