DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe conveyor suitable for use in a dross recovery apparatus for recovering dross generated during melting by separating it from molten metal.

[0002]

2. Description of the Related Art Conventionally, dross (metal oxide floating on a molten metal) generated in a melting furnace during melting has been recovered by scooping.

[0003]

However, as described above, when the dross is scooped, there is a problem in that when the dross is scooped, the molten metal is scooped together. In particular, when the viscosity of the molten metal is high, the dross and the molten metal are difficult to separate, and the amount of the molten metal that is scooped together with the dross increases, and the production amount of the molten metal decreases by that much, thereby increasing the yield. There was a problem that it caused deterioration. In addition, since dross and molten metal are collected in a entangled state, it is impossible to separate dross and molten metal even after solidification and cooling, and all molten metal is disposed of in the same manner as dross. There was a problem of increasing. Therefore, the present inventors have conducted intensive studies to solve the above problems, and as a result, a shooter that drops dross, a transfer vibrator that is provided below an outlet of the shooter, and applies vibration to the dross, Developed a new dross collection device equipped with a pipe conveyor connected to the conveyor vibrator and rotating around the axis, and a collection box provided below the discharge end of the pipe conveyor and containing the dross. did. In this case, if a normal pipe conveyor is used, the dross discharged from the discharge end of the pipe conveyor falls to a certain position in the collection box, so only that portion rises, and the dross is uniformly distributed in the collection box. There is a problem that it is not stored and collection efficiency is poor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to drop a conveyed object from a discharge end of a rotating pipe so as to be uniformly distributed.
An object of the present invention is to provide a pipe conveyor capable of efficiently and reliably collecting a conveyed object.

[0005]

In order to achieve the above object, the present invention relates to a pipe conveyer for feeding a conveyed article into a rotatable pipe rotatably provided around an axis and conveying the conveyed article. Is formed with a notch at the discharge end.

[0006]

According to the pipe conveyor of the present invention, the notch formed at the discharge end of the rotating rotary pipe is provided.
The conveyed material introduced into the rotating pipe does not fall from the unloading end of the rotating pipe to a certain position, but is dispersed to each part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIGS. 1 to 3 show one embodiment of the present invention. In these drawings, reference numeral 1 denotes a gutter. A tundish 2 is installed below the tip of the gutter 1, and a mold is installed below the tundish 2. Above the base end of the gutter 1, a furnace body 3 is installed so as to be tiltable. And the said gutter 1 is provided movably in the direction orthogonal to the longitudinal direction,
It can be moved by a power cylinder (not shown) connected to the gutter 1. Further, a bracket 4 is provided on the side of the base end (pool section) 1a of the gutter 1.
The shooter 5 is provided rotatably in the up and down direction by a pin 6 through the
a is inserted in a state of being in contact with the storage tank 70 of the transport vibrator 7. The bottom of the storage tank 70 of the transport vibrator 7 is inclined downward toward the tip, and both ends of the storage tank 70 are supported by a vibration support member 71 so as to be able to vibrate. 70 is configured to be vibrated by a vibration motor 72 provided on the back surface thereof. Furthermore, the tip of the storage tank 70 is inserted into the carry-in end of the rotating pipe 80 of the pipe conveyor 8, and the rotating pipe 80 is connected to a rotating support member 82
Thereby, it is rotatably supported with the carry-out end side inclined downward. A rotating machine 83 installed on a base 81 is connected to the rotating pipe 80, and the rotating machine 83 controls the rotating direction and the number of rotations of the rotating pipe 80. . Further, as shown in FIG. 3, a half cut-out 80a is formed at the discharge end of the rotary pipe 80. Below the unloading end of the rotary pipe 80, a collection box 9 is mounted on a traveling cart 100 of an inclined conveyor 10, and the traveling cart 100 is moved along a guide rail 101 in FIG. It is configured to run in a direction perpendicular to the paper surface.

When a large amount of dross before and after the molten metal is discharged from the furnace body 3 is recovered by using the dross recovery apparatus configured as described above, the gutter 1 is placed directly below the outlet of the furnace body 3. To the gutter 1 via the bracket 4
The dross is scraped directly from the inside of the furnace body 3 into the shooter 5 while the shooter 5 connected by the above is positioned immediately below the tap hole of the furnace body 3. In addition, a small amount of dross generated during casting is once dropped into the gutter 1 from the tap hole of the furnace body 3, and is scraped into the shooter 5 from the pool 1 a of the gutter 1. The dross scraped into the shooter 5 in this manner is transferred by the shooter 5 to the transport vibrator 7.
Is received in the storage tank 70 from the discharge port 5a along the inclination of the shooter 5 under the vibration from the storage tank 70. Next, the dross stored in the storage tank 70 is finely separated by the vibration of the vibration motor 72 and is sent downward along the inclination of the bottom of the storage tank 70 while forming a lump of several tens of mm. Further, the dross introduced into the rotating pipe 80 from the tip of the storage tank 70 is rotated by the rotating pipe 80.
With the rotation of, the dross and the molten metal are dropped and collected into the collection box 9 from the discharge end of the rotating pipe 80 in a state where the dross and the molten metal are separated into fine particles of about several mm. In this case, a half-cut notch 80a is formed at the discharge end of the rotary pipe 80, so that the rotary pipe 8
With the rotation of 0, the discharge position of the dross is
a base end face portion 80b, both side face portions 80c and rotating pipe 8
0 and the collection box 9
The dross falling position is dispersed in each part, and the dross can be uniformly stored in the collection box 9. When the dross is full in the collection box 9, the collection box 9 is carried out by the inclined conveyor 10 and replaced with an empty collection box 9.

As described above, dross can be collected smoothly. In this case, since the dross is scraped into the shooter 5, the amount of the molten metal taken out together with the dross is extremely reduced, and only the dross can be recovered, so that the production amount of the molten metal increases and the yield can be improved. In addition, since the shooter 5 is connected to the movable gutter 1, the dross can be always collected regardless of before and after tapping or during casting, so that the collection operation can be efficiently performed. Further, since the shooter 5 is pin-coupled to the gutter 1 and is always in contact with the transport vibrator 7, the vibration of the transport vibrator 7 is transmitted to the shooter 5, and the shooter 5 is vibrated, so that the dross in the shooter 5 is removed. Falling is performed smoothly. Furthermore, Dross
Since it is decomposed into granules by the transport vibrator 7 and the pipe conveyor 8, the molten metal scraped out together with the dross can be easily separated from the dross, and only the dross can be collected, thereby reducing the amount treated as dross. be able to. Also, since a half cut-out 80a was formed at the discharge end of the rotating pipe 80 of the pipe conveyor 8,
By appropriately controlling the rotation direction and the number of rotations of the rotating pipe 80, the dross can be uniformly accommodated in the collection box 9 and the collection efficiency can be improved.

In this embodiment, a half cut-out 80a is formed at the discharge end of the rotary pipe 80 of the pipe conveyor 8.
However, the present invention is not limited to this, and the cutout portion can be appropriately selected, such as 1/3, 2/3, etc., instead of half (1/2). In addition, as shown in FIG. 4, a plurality of cutouts 80e may be formed around the circumference of the rotary pipe 80, and further, as shown in FIG.

[0012]

As described above, the present invention relates to a pipe conveyor for feeding and transporting a conveyed material into a rotary pipe provided rotatably around an axis, wherein a notch is provided at a discharge end of the rotary pipe. Since it is formed, by the notch, the conveyed material input into the rotating pipe does not fall to a fixed position from the discharge end of the rotating pipe, but is dispersed to each part, so that the conveyed material is uniformly distributed. The rotating pipe can be dropped from the discharge end so as to be distributed, and the conveyed material can be efficiently and reliably collected.
