Technical Field

[0002] In the production of copper strips and rods, the addition of rare earth elements can significantly improve the mechanical properties, electrical properties, and corrosion resistance of copper materials. Traditional rare earth wire feeders use open-type wire feeding tubes to deliver rare earth wires into the furnace. However, this method generally suffers from the following problems: 1) Open-type wire feeding tubes easily lead to partial oxidation of the rare earth wires before they enter the furnace, forming oxide inclusions and reducing rare earth utilization; 2) The wire feeding speed cannot be adjusted in real time, easily causing fluctuations in rare earth concentration; 3) The lack of a stirring function easily leads to uneven distribution of rare earth elements within the furnace; 4) The melting and holding furnace itself lacks a degassing device, making it difficult to remove oxygen and hydrogen from the molten copper; 5) The contact points between the wire feeding tube and the molten copper require frequent replacement due to high-temperature oxidation and erosion, resulting in a short service life. Therefore, these problems urgently need to be solved. Utility Model Content

The rotation direction of each pressure roller 10 is consistent with the forward direction of the rare earth wire 3, and the rare earth wire 3 is pressed tightly onto the drum 4 by the pressure rollers 10, thereby ensuring that the rare earth wire 3 is fed in an orderly manner.

[0035] This utility model also features symmetrically arranged vertical lifting components 6 on the lower surface of the housing 1, with the lifting actions of the two lifting components 6 synchronized.

Each lifting component 6 includes a housing 61, a threaded rod 62, a main bevel gear 63, a driven bevel gear 64, a second motor 65, a second sleeve 66, a slide rod 67, and a guide rail 68.

Each box 61 is a hollow cuboid structure, and a circular hole is embedded in the middle of its upper surface. Each circular hole is connected to the interior of the corresponding box 61. A threaded rod 62 is vertically installed in the middle of the interior of each box 61. The diameter of each threaded rod 62 is smaller than the diameter of the corresponding circular hole.

Each second sleeve 66 is screwed to the corresponding threaded rod 62, and its upper end extends vertically upward through the circular hole to the upper surface of the corresponding housing 61, and is fixedly connected to the lower surface of the housing 1 at the corresponding position. Then, driven by the second motor 65, the housing 1 is driven to move vertically up and down through the meshing of the main bevel gear 63 and the driven bevel gear 64. The upper limit position of the housing 1 must ensure that the ceramic blade 16 is removed from the copper liquid surface, and the lower limit position must ensure that the lower half of the inclined section of the graphite shaft 14 is inserted into the copper liquid.

[0038] The working principle of this utility model:
[0039] First, the ceramic blade 16 is inserted into the copper liquid, and the depth of the graphite shaft 14 inserted into the copper liquid is adjusted under the drive of the lifting component 6. Then, inert gas enters through the air inlet pipe 11 and escapes through the channel II 19, through hole II, annular hole and air hole 17 in sequence, driving the ceramic blade 16 to rotate and stir, thereby removing gas from the copper liquid. At the same time, under the drive of the first motor 2, the rare earth wire 3 on the drum 4 is fed through the channel I 18. During this process, the stirring of the ceramic blade 16 ensures that the rare earth elements are evenly distributed, and the rare earth wire 3 is protected during the feeding process by the cooperation of the protective roller 12 and the support roller 13. The rare earth wire 3 can be fed in an orderly manner by the cooperation of the electric push rod 8, the pressure claw 9 and the pressure roller 10.

[0042] (2) By cooperating with the first motor 2 and the drum 4, the feeding speed of the rare earth wire 3 can be controlled in real time, thereby avoiding fluctuations in rare earth concentration and improving the uniformity of rare earth distribution.
[0043] (3) By setting the lifting component 6, the depth of the graphite shaft 14 inserted into the copper liquid can be controlled;
