Abstract

The present invention relates to an apparatus for removing top dross of a plating pot where a snout and an air knife are arranged, the snout being arranged between the front end region and the rear end region of a plating pot. The present invention provides an apparatus for removing top dross of a plating pot, the apparatus comprising: a first wiping means which is mounted on the plating pot and is arranged between the snout and the air knife so as to be movable in the width direction of the plating pot; a second wiping means which is mounted on the plating pot and is rotatably arranged between the air knife and the first wiping means so as to transfer, to the rear end region, the top dross transferred by the first wiping means; and a third wiping means which is mounted on the plating pot and is rotatably arranged between the air knife and the front end region so as to transfer the top dross to the front end region. Thereby, the present invention provides an advantageous effect of effectively removing dross.

First claim

The invention claimed is:

1. An apparatus for removing top dross of a plating pot comprising:
a first magnetic wheel mounted in the plating pot;
a second magnetic wheel mounted in the plating pot; and
a third magnetic wheel mounted in the plating pot;
wherein the first magnetic wheel is arranged to linearly reciprocate in the width direction of the plating pot between a snout and air knives based on a longitudinal direction of the plating pot such that a top dross in front of the snout is transferred to both sides of the plating pot,
the second magnetic wheel is arranged to be pivotable on one side based on the width direction of the plating pot behind the air knives based on the longitudinal direction of the plating pot, so that the top dross transferred by the first magnetic wheel is transferred around a rear sidewall of the plating pot, and
the third magnetic wheel is arranged to be pivotable on the other side based on the width direction of the plating pot in front of the air knives based on the longitudinal direction of the plating pot, so that a top dross in front of and on a side of the air knives is transferred around a front sidewall of the plating pot.

2. The apparatus of claim 1 , further including a plurality of motors connected to the first magnetic wheel, the second magnetic wheel and the third magnetic wheel, respectively.

3. The apparatus of claim 1 , wherein the second magnetic wheel is disposed on one side based on a virtual reference line that passes a center in the lateral direction of the plating pot, and the third magnetic wheel is disposed on the other side of the reference line.

4. The apparatus of claim 3 , wherein the second magnetic wheel is disposed at a corner of the plating pot.

5. The apparatus of claim 4 , wherein the third magnetic wheel is disposed at a corner of the plating pot.

6. The apparatus of claim 1 , wherein each of the first magnetic wheel, the second magnetic wheel and the third magnetic wheel comprise a shaft and a magnet combined with an outer circumferential surface of the shaft, respectively.

7. The apparatus of claim 2 , wherein each of the first magnetic wheel, the second magnetic wheel and the third magnetic wheel comprise a housing that covers each of the magnetic wheels.

8. The apparatus of claim 7 , wherein each of the housings are formed in a shape that surrounds the magnetic wheel to allow the magnetic wheel to be rotatably combined therewith and wherein each of the housings comprise a body with an upper cover combined with an open top surface of the body, and a lower cover combined with an open bottom surface of the body.

9. The apparatus of claim 8 , wherein the lower cover for each of the magnetic wheels comprises a cylindrical surface corresponding to a surface of each of the magnetic wheels.

10. The apparatus of claim 9 , wherein the upper cover and the lower cover for each of the housings are formed of a stainless material through which uplift force and drag for each of the magnetic wheels penetrate.

11. The apparatus of claim 10 , further comprising a first body accommodating a motor to rotate the first magnetic wheel, a second body accommodating a motor to rotate the second magnetic wheel and a third body accommodating a motor to rotate the third magnetic wheel, wherein the first body, the second body, and the third body each comprise an inlet and an outer connected to the outside, the apparatus further comprising a supply tube connected to the inlets and a cooling fluid supplier connected to the supply tube to supply a cooling fluid to the supply tube.

12. The apparatus of claim 11 , wherein the supply tube is formed of a flexible material and comprises a plurality of blades that induces a vortex of the cooling fluid, in the supply tube.
