Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floating matter collection device for collecting foreign matter floating on a liquid surface.

2. Description of the Related Art Conventionally, foreign matter floating on the liquid surface, such as sludge 2 floating on the surface of the molten metal bath, was removed from the surface of the bath using a suction device or a ladle.

Problems to be Solved by the Invention However, foreign substances floating on the liquid surface are floating in fractions over the entire liquid surface, and in order to remove them, one suction port of the suction device, the so-called suction head, must be used. The object of suction must be moved to the required area of the liquid surface on which the foreign object is floating, and in the work of scooping up the foreign object with a ladle,
Workers had to move around, which caused problems in terms of work efficiency. However, V also poses a problem in terms of removal efficiency, as foreign matter floats in fractions on the liquid surface, resulting in a thin layer of foreign matter and the liquid being removed along with the foreign matter.

The present invention solves the above-mentioned problems, and an object of the present invention is to provide a floating object collecting device that collects only floating foreign objects on the liquid surface in order to efficiently remove foreign objects.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a Vr-spiral feed blade which is formed around the rotational axis in the horizontal direction, and which is interlocked and connected to the n1 rotational drive device at a 1d position. The screw that is
In addition to immersing the sending blade in the liquid surface where foreign objects are floating,
The distance from the liquid level to the rotational axis is set constant, and a side wall is arranged near -II of the screw to guide foreign matter conveyed by the screw in the direction of the rotational axis.

Effect In the above configuration, the screw is rotated by the rotary drive device. Then, the foreign matter and liquid corresponding to the feed blade are conveyed in the direction of the rotation axis while sliding on the surface of the feed blade. At this time, the foreign matter and liquid are sent out to the side wall II via the rotation axis by the holding angle of the feed vane, and are then guided by the inner wall and transported in the direction of the rotation axis. Further, foreign matter floating on the liquid surface adjacent to the screw sequentially flows into the surface side of the feed vane. This causes a flow of foreign matter toward the screw on the liquid surface, and attracts foreign matter floating on the liquid surface that has leaked from the screw. Therefore, the foreign matter floating on the liquid surface is attracted by the screw and is transported in the direction of the rotational axis, so that it is deposited on the downstream side in the transport direction.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings. 1 to 3, bath water 2 at the melting end is stored in a molten metal pot 1, and dross 4, which is a foreign substance, is floating on the molten metal surface 3 of this molten metal 2. On the molten metal surface 3 of the molten metal pot 1, the actual harvesting device main body 5 is arranged with its lower part immersed below the molten metal surface 3. The actual collection device main body 5 includes a box 6 whose upper and lower surfaces are open, and a guide plate 7 formed by extending one side wall of the box 6. The screw 8 is arranged with the rotating shaft 9 parallel to the guide plate 7, and the rotating shaft 9 has one end attached to the box body 6.
The other end is rotatably supported by a support plate 10 formed at the other end of the guide plate 7. Further, a spiral feeding blade 11 is formed around the rotating shaft 9, and the screw 8 positions the rotating shaft 9 with a gap between the molten metal 1ij3 and the feeding blade 11 below the molten metal surface 3. It is provided by being immersed in it. An opening 12 facing the screw 8VC is formed in the side wall of the box 6 that is located forward in the axial direction of the rotating shaft 9 and supports one end of the rotating shaft 9. However, the other end of the rotating shaft 9 is connected via a universal joint 13 to a motor 14 which is a rotational drive device.

Hereinafter, the effects of the above configuration will be explained.

First, the screw 8 is rotated by the motor 14 so that its feed blade 11 is sent toward the box body 6 side.

Then, while sliding the dross 4 and molten metal 2 corresponding to the feeding blades 11 on the surface of the feeding blades 11, the opening 14 of the box body 6
send it towards. Due to this 1￥f and the holding angle of the feed blade 11, the molten metal 2 and the dross 4 are urged in the direction of following the lower part of the rotary shaft 9, being sent to the guide plate 7 side, and separating from the screw 8. However, the guide plate 7 prevents the paper from separating, and the paper is transported along the guide plate 7. However, on the side opposite to the guide plate 7 via the rotating shaft 9, the dross 4 floating on the molten metal f:fJ3 adjacent to the screw 8iC sequentially flows into the back side of the feed blade 11. As a result, a flow 15 of dross 4 toward the screw 8 is generated on the bath surface 3, and the dross 4 floating on the bath surface is attracted away from the screw 8.

Then, the dross 4 and the molten metal 2 that have flowed into the box 6 from the opening 12 are separated by floating the dross 4 on the molten metal surface 3 within the box 6. At this time, the top surface of the box 6 is open, and the molten metal surfaces 3 inside and outside the box 6 are kept at the same level by atmospheric pressure, so the molten metal 2 that has flowed into the box 6 is
11E Next, the water flows out of the box 6 from the open bottom surface of the box 6. As a result, in the box body 6, only the amount of dross 4 that remains floating on the molten metal surface 3 increases, and the layer of dross 4 becomes thicker.
It becomes easy to remove the dross 4 without causing any damage. Therefore, according to this embodiment, I on the molten metal surface 3
Since the dross 4 that is idle at C1 is collected and collected in one place by V'c, it is possible to improve the work efficiency of the dross 4 collection work.
Moreover, since only the dross 4 is multiplied and stays in the box 6, the removal efficiency can be improved.

Further, in this embodiment, the guide plate 7 is arranged near the negative side of the screw 8, but the screw 8
It may be arranged in the vicinity of the inner wall 1a of the molten metal container 1 along the inner wall 1a, and the guide plate 7 may act on the inner wall 1a. Of course, in the above configuration, the guide plate 7 is unnecessary. In this example,
Although dross floating on the surface of molten metal has been described, it is clear that similar effects can be obtained with respect to foreign matter floating on the surface of other liquids. Next, FIG. 4 shows another embodiment of the present invention, and the same members as those in the previous embodiment are given the same numbers and the explanation thereof will be omitted. In this embodiment, a plurality of screws 17 are arranged in series along the opening periphery of the molten metal pot 1 so that the base and tip of each screw 1 are adjacent to each other, and the dross on the molten metal surface 3 is This is intended to be a complete collection of 4. Further, it is also possible to arrange the plurality of screws 17 in an L shape or a modified shape.

Effects of the Invention As described above, according to the present invention, foreign matter floating on the liquid surface can be collected in one place on the liquid surface, so it is possible to improve the work efficiency and removal efficiency of the collection work. Bring it in.
