Description

Technical Field

[0001] The utility model belongs to the technical field of wire production, and more specifically, relates to a metal solution stirring and degassing device. Background Art

[0002] During the production of hot-dip tin wire, when the copper strip passes through the tin pot, alloy elements such as copper and zinc in the copper alloy will displace the liquid tin. As production continues, the content of impurity elements in the tin liquid accumulates due to the displacement reaction. The addition of elements such as copper and zinc will continuously increase the melting point of the tin liquid, resulting in increased production energy consumption and threatening the stability of the hot-dip quality. Moreover, once the content of impurity elements in the tin liquid exceeds the standard, the entire pot of tin liquid cannot be used for hot-dip production; in addition, during the melting of tin ingots and the production process, the gas generated by impurities is not easily precipitated in the viscous metal solution and is easily carried by the tin liquid to the strip coating during production and ruptures, causing quality problems. Therefore, after a period of production, the tin pot needs to be hoisted to the hot-dip holding furnace to cool down so that the impurity elements in the tin liquid crystallize and separate from the tin liquid. During this process, it is necessary to continuously stir to make the bubbles in the tin liquid float up, rupture and overflow, and the impurity elements deposited at the bottom come into contact with the air to form slag. The slag is suspended in the tin liquid, and the operator uses a slag ladle to fish out the slag to achieve the purpose of improving the quality of the tin liquid. Defects of the prior art: The formation of slag requires continuous stirring of the tin liquid to contact with the air. However, the specific gravity of tin is relatively large, and manual stirring has a high labor intensity. The physical strength of personnel is limited, and continuous and uniform stirring cannot be achieved, resulting in poor purification of the tin liquid and degassing effects, and unstable tin plating quality.

[0023] As shown in the attached Figure 1 - Attached Figure 4As shown in the figure, the present utility model is a metal solution stirring and degassing device. The first rotating motor 1 is connected to the frame 2. A linear guide rail 3 is provided on the frame 2. The swing arm 4 is movably sleeved on the frame 2 through a notch 5.

The second rotating motor 9 is connected to a rotating shaft 10. The lower end of the rotating shaft 10 is connected to an impeller 11. With the above structure, in view of the deficiencies in the prior art, an improved technical solution is proposed. When the structure is set up, it includes the frame 2, the swing arm 4, the rotating shaft 10, the impeller 11, etc. The first rotating motor 1 is connected to the frame 2. When the first rotating motor 1 rotates, it can drive the frame 2 to rotate, thereby realizing the horizontal swing of the swing arm 4 and realizing the rotational movement between the standby position (away from the solution crucible) and the working position (above the solution crucible). A linear guide rail 3 is provided on the frame 2. The swing arm 4 is movably sleeved on the frame 2 through a notch 5. The linear guide groove 6 on the inner surface of the notch 5 is movably clamped on the linear guide rail 3. A lifting motor 7 is provided on the side of the frame 2. The lifting motor 7 is connected to one end of the swing arm 4 through a chain 8. In this way, when controlling the rotation of the lifting motor 7, the lifting motor drives the chain to rotate, and the chain 8 drives the swing arm to move up and down along the frame. The cooperation of the linear guide groove and the linear guide rail ensures that the swing arm can only move up and down relative to the frame and cannot rotate. A second rotating motor 9 is provided at the other end of the swing arm 4. The second rotating motor 9 is connected to the rotating shaft 10. The lower end of the rotating shaft 10 is connected to the impeller 11. In this way, when the second rotating motor 9 rotates, it drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the impeller 11 to rotate. When it is necessary to stir the metal solution, by controlling the rotation of the first rotating motor 1, the swing arm 4 is driven to rotate in one direction, and it rotates and moves from the standby position (away from the solution crucible) to the working position (above the solution crucible). Then, control the rotation of the lifting motor 7 to drive the swing arm 4 to descend relative to the frame 2, and the impeller 11 descends into the metal solution in the solution crucible 17. Then, control the rotation of the second rotating motor 9 to drive the impeller 11 to rotate through the rotating shaft 10, realizing the stirring of the metal solution. The stirring function stirs the tin solution through the controlled rotating shaft and impeller. According to the on-site requirements, the rotation speed can be adjusted to achieve the stirring purpose, so as to purify the molten solution and make the composition uniform. When stirring is not required, control the second rotating motor 9 to stop rotating. Then, control the rotation of the lifting motor 7 to drive the swing arm 4 to rise relative to the frame 2. Then, control the rotation of the first rotating motor 1 to drive the swing arm 4 to rotate horizontally in the other direction, and the swing arm 4 moves from the working position (above the solution crucible) to the standby position (away from the solution crucible). The metal solution stirring and degassing device described in the present utility model has a simple structure and can conveniently and automatically realize the stirring of the metal solution, enabling the bottom impurities to contact the air to form tin slag, and increasing the stirring uniformity, achieving the purpose of purifying the molten solution and making the composition uniform. During operation, manual stirring is not required, reducing the labor intensity, and there is no need for personnel to only operate, effectively reducing the risk of personnel being injured.

[0024] The rotating shaft 10 and the impeller 11 are both of hollow structures. The hollow structures of the rotating shaft 10 and the impeller 11 form an inert gas supply channel 15, and air outlet holes are provided on the impeller 11. The upper part of the rotating shaft 10 is connected to an inert gas supply pipeline 16 through a rotary seal structure. With the above structure, the supply of inert gas is carried out while stirring. The pressurized inert gas is pressed into the tin liquid and will be broken into tiny bubbles, which are evenly dispersed in the tin liquid metal, and the partial pressure of the gas in the bubbles is zero. Since the partial pressure of the impurity gas in the tin liquid is high, the gas in the tin liquid continuously diffuses into the bubbles. At the same time, some non-metallic inclusions in the tin liquid are adsorbed on the surface of the bubbles, and the useless hydrogen gas and some non-metallic inclusions adhering to the inert gas bubbles float to the liquid surface, achieving the degassing effect. The rotating shaft 10 is connected to the inert gas supply pipeline 16 through a rotary seal structure. The rotary seal structure is a product in the prior art, which does not affect the rotation of the rotating shaft and ensures the sealing of gas supply at the same time.

[0025] The lower part of the described frame 2 is movably sleeved and connected with a rotary support 12.

With the above structure, when the lifting motor rotates, it drives the chain to continuously rotate, drives the swing arm to lift relative to the frame, realizes the height adjustment of the swing arm, and meets the use requirements.

[0028] The described metal solution stirring and degassing device is arranged close to the solution crucible 17. When carrying out stirring and degassing operations, the impeller 11 of the metal solution stirring and degassing device is located above the bottom of the solution crucible 17. With the above structure, it meets the requirements of stirring and degassing. When stirring and degassing are not required, the swing arm leaves the solution crucible 17, and then the impeller also leaves the solution crucible 17 and enters the standby position.

[0029] A first speed reducer 18 is arranged between the first driving gear and the first driven gear. A second speed reducer 19 is arranged between the second driving gear and the second driven gear. With the above structure, the speed reducer is configured between the motor and the corresponding gear to achieve speed reduction during control.

[0030] A belt is sleeved between the gear on the rotating shaft of the second rotating motor and the gear on the rotating shaft, so that the rotation of the rotating shaft 10 can be reliably driven by the rotation of the second rotating motor.

[0031] The metal solution stirring and degassing device described in the present utility model, when configured, includes a frame 2, a swing arm 4, a rotating shaft 10, an impeller 11, etc. The first rotating motor 1 is connected to the frame 2.

A linear guide rail 3 is provided on the frame 2. The swing arm 4 is movably sleeved on the frame 2 through a notch 5. The linear guide groove 6 on the inner surface of the notch 5 is movably clamped on the linear guide rail 3. A lifting motor 7 is provided on the side of the frame 2. The lifting motor 7 is connected to one end of the swing arm 4 through a chain 8. In this way, when controlling the rotation of the lifting motor 7, the lifting motor drives the chain to rotate, and the chain 8 drives the swing arm to move up and down along the frame. The cooperation of the linear guide groove and the linear guide rail ensures that the swing arm can only move up and down relative to the frame and cannot rotate. A second rotating motor 9 is provided at the other end of the swing arm 4. The second rotating motor 9 is connected to the rotating shaft 10. The lower end of the rotating shaft 10 is connected to the impeller 11. In this way, when the second rotating motor 9 rotates, it drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the impeller 11 to rotate. When metal solution stirring is required, by controlling the rotation of the first rotating motor 1, the swing arm 4 is driven to rotate in one direction, rotating and moving from the standby position (away from the solution crucible) to the working position (above the solution crucible). Then, by controlling the rotation of the lifting motor 7, the swing arm 4 is driven to descend relative to the frame 2, and the impeller 11 descends into the metal solution in the solution crucible 17.
