Description

[Detailed explanation of the invention] (A) Industrial application field This invention is applicable to the following steps:
This invention relates to an improvement in a supply device for supplying a powder such as Fe-Si to a pouring stream from a container attached to a ladle.

(B) Prior art Conventionally, a powder supply device in a ladle has a mechanism that opens and closes a shutter in some way at the supply port to supply or stop the supply of powder, but There were cases where the shutter malfunctioned due to this.

In addition, since this type of feeding device is installed on a tilting ladle, the feeding port must always be kept constant in order to maintain a constant supply amount, so the supporting mechanism of the device is complicated, such as using links. It used to be.

(C) Problems that the present invention aims to solve Therefore, in order to solve the above problems, the present invention aims to solve the above problems.
First, to prevent the powder from getting caught, do not use a shutter at the supply port and open and close the cover, which may result in malfunction of the powder supply, that is, the powder may not be supplied or the supply may not stop. Secondly, in order to quantify the supply amount, the supply port is placed in a plane perpendicular to the tilting direction of the supply device, that is, in a position that always maintains verticality even when the supply device is tilted. It is an object of the present invention to provide a device for supplying powder in a ladle which solves the above-mentioned problems by being able to always supply a constant amount even if the powder is tilted with the tilting of the ladle.

(D) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a powder supply device that is attached above the ladle and tilts with the tilting of the ladle. An opening/closing cover is opened on the side of the container body in a direction perpendicular to the supply port, and an opening/closing cover that contacts the supply port is attached to a rotating shaft at the top of the container body so as to be rotatable in the same direction as the opening direction of the supply port. It is an object of the present invention to provide a powder supply device in a ladle, which is characterized in that it is interlocked with a powder supply device in a ladle.

(E) Examples The following will explain the embodiments shown in the drawings.

The powder supply device 1 according to the present invention is shown in FIG.
and a mounting rod 3 on the ladle 2 as shown in FIG.
As shown in FIGS. 4A and 4B, when the ladle 2 is tilted, the feeding device 1 is also tilted.

In addition, 4 and 4' in the figure are operation wires.

The details of the structure of the supply device 1 are shown in FIGS. 1A and 1B. The supply device 1 consists of a container body 5 with a supply port 8 opened, an opening/closing cover 6 for closing the supply port 8, and a rotating shaft 7 for attaching the opening/closing cover 6 installed above the container body 5. Operation wire 4,
It is linked with 4'.

The supply port 8 is opened at the lower part of the side surface of the container body 5 in a direction perpendicular to the tilting direction of the ladle 2, that is, the side surface that always remains vertical even when the container body 5 is tilted at the same time as the ladle 2.

The opening/closing cover 6 is a long plate-shaped member whose lower part is located below the supply port 8 and whose upper part is located above the rotation axis 7 above the container body 5. It is attached to the rotating shaft 7 at a position slightly above, with the attachment portion of the upper operating wire 4 remaining above. The rotation direction of the opening/closing cover 6 is relative to the opening direction of the supply port 8 of the container body 5.

Regarding the relationship between the supply port 8 and the opening/closing cover 6, a concave fitting groove 9 is formed around the supply port 8 of the container body 5, and a fitting protrusion that matches the concave fitting groove 9 is formed on the opening/closing cover 6. 10 are formed, and the circular donut shapes are interlocked with each other to prevent the powder from spilling out from the gap between the opening/closing cover 6 and the container body 5.

The operating wire 4 is connected to the upper and lower parts of the attachment position of the opening/closing cover 6 to the rotating shaft 7, and is opened by pulling the upper wire 4 and pushing the lower wire 4'. It is closed by pulling 4', and the supply port 8
Supply and stop the powder.

In addition, 11 in the figure is a partition plate for making it easier to supply the powder agent in the container body 5.

(F) Effect Next, the operation of the present invention will be explained.

In the initial state shown in FIG. 4B, the opening/closing cover 6 is closed as shown in FIG. 1B, so no powder is supplied.

When the operating wires 4, 4' are operated, the opening/closing cover 6 opens and the powder starts to be supplied. This state is shown in FIG. 4A and FIG. 1A.

When the operating wires 4, 4' are moved in the opposite direction, the opening/closing cover 6 rotates counterclockwise around the rotating shaft 7, closes the supply port 8, and stops supplying the powder.
Return to initial state.

(G) Effects of the present invention The present invention is constructed and operates as described above, and thus exhibits the following effects.

First, the supply port 8 of the supply device 1 supplies and stops the powder by opening and closing the opening/closing cover 6, not by opening and closing the shutter, so there is no influence of powder getting caught, resulting in malfunction. All of them disappeared.

Second, even if the supply device 1 is tilted with the tilting of the ladle 2, the supply port 8 is provided in a place that maintains a vertical position, so that a constant amount of powder can be supplied at all times.
