Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy melt purification, in particular to an aluminum alloy melt purification treatment device. Background Art

[0002] Aluminum alloy is a common metal material, widely used in the automotive, industrial, construction and other industries. It is rust-resistant and strong. During the production process, aluminum alloy is made by cooling the solution. In order to ensure the quality of the aluminum alloy material, it needs to be purified in the solution state. During the purification, a purification device is needed.

[0003] When purifying aluminum alloy melt, an inert gas purification method is usually used. The inert gas purification method generally involves first adding a prepared degassing agent solution into a solvent furnace, then placing the aluminum alloy into the solvent furnace for smelting, and finally, when the temperature of the aluminum alloy melt reaches the boiling point of the degassing agent, introducing an inert gas (such as nitrogen or argon) into the melt for degassing. In order to ensure that the melt can be better degassed, a degassing agent must be added to the solvent furnace first. In the prior art, the degassing agent is generally injected directly into the solvent furnace. After entering the solvent furnace, the degassing agent will directly flow into the bottom of the solvent furnace. After the aluminum alloy is melted, it will be difficult for the degassing agent solution at the bottom to contact the furnace wall. This will result in a slower purification rate for the aluminum alloy solution located at the furnace wall.

[0004] Therefore, we disclose an aluminum alloy melt purification treatment device to meet people's needs. Utility Model Content

After the aluminum alloy is melted, it will be difficult for the position located at the furnace wall to contact with the degassing agent solution at the bottom, which will cause the aluminum alloy solution located at the furnace wall to be purified at a slower rate.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an aluminum alloy melt purification treatment device, comprising a furnace, a base is installed on the upper side of the furnace, a lifting assembly is installed on the upper side of the base, a furnace cover is installed on the base through the lifting assembly, a gas injection hole is opened on one side of the furnace, a discharge port is opened on the surface of the furnace, a sealing plate is rotatably installed in the discharge port, a rotating hole is opened on the upper side of the furnace cover, a stirring assembly is installed in the rotating hole, the stirring assembly comprises a driving pipe, a transmission pipe is installed at the bottom end of the driving pipe, a plurality of material guide holes are opened on the surface of the transmission pipe, stirring pipes are installed in each of the plurality of material guide holes, the surface driving unit of the driving pipe, and an injection assembly is installed on the top of the transmission pipe.

[0026] Based on the above structure, the base 2 is installed in the upper area of ​​the surface of the furnace 1. The lifting assembly can drive the furnace cover 3 to move vertically up and down to open and close the furnace 1. A corresponding heating plate is arranged inside the furnace 1, and the aluminum alloy inside is heated by the heating plate arranged inside the furnace 1. When the furnace 1 is performing preparatory work, it is necessary to connect the gas injection hole 19 to an inert gas, and the injection assembly also needs to be connected to an external degassing agent. The stirring assembly is installed on the furnace cover 3. The driving pipe 9, the transmission pipe 10 and the stirring pipe 11 in the stirring assembly are all hollow structures and are connected. The connection is sealed to facilitate the delivery of the degassing agent. The stirring pipe 11 is staggered and installed on the surface of the transmission pipe 10 to facilitate stirring of the melt.

[0027] Example 2

[0028] like Figure 3 As shown, the driving unit includes a primary bevel gear 16, which is installed on the surface of the driving tube 9. A stirring motor 17 is installed on the upper side of the furnace cover 3, and a secondary bevel gear 18 is installed on the output end of the stirring motor 17. The primary bevel gear 16 is meshed with the secondary bevel gear 18. The rotation of the primary bevel gear 16 drives the secondary bevel gear 18 to rotate, thereby driving the driving tube 9 to rotate, providing stirring power for the stirring tube 11.

[0029] Example 3

[0030] like Figure 3 As shown, the injection assembly includes an injection pipe 14, two fixed columns 12 are installed on the upper side of the furnace cover 3, the same fixed plate 13 is installed on the upper side of the two fixed columns 12, the injection pipe 14 is installed on the fixed plate 13, a valve 15 is installed on the injection pipe 14, the bottom end of the injection pipe 14 is rotatably connected to the top end of the driving pipe 9, a spray unit is installed on the inner wall of the stirring pipe 11, and the connection between the injection pipe 14 and the driving pipe 9 is sealed with rubber, and no leakage will occur during the rotation process.

An arc-shaped nozzle is opened on one side of the piston 22, and one end of the arc-shaped nozzle is located on one side of the piston 22, and the other end is located on the surface of the piston 22 and penetrates the piston 22. When the arc-shaped nozzle is located outside the stirring tube 11, the degassing agent will be directly sprayed out through the arc-shaped nozzle. Due to the shape characteristics of the nozzle design, when the stirring tube 11 moves, the degassing agent will be sprayed in a fountain-like manner. When the supply of degassing agent is stopped, the piston 22 is retracted by the reaction force of the spring 23; the degassing agent enters the transmission tube 10 through the driving tube 9, and then enters the stirring tube 11 installed on the surface of the transmission tube 10. The piston 22 is pressed by the pressure of the liquid flow itself. The piston 22 slides along the inner wall of the stirring tube 11 after being pressed. When the arc-shaped nozzle on the surface of the piston 22 is separated from the inner wall of the stirring tube 11, the degassing agent is sprayed out through the arc-shaped nozzle and sprayed onto the inner wall of the furnace 1. After ensuring that the inner wall of the furnace 1 is evenly sprayed, the control valve 15 closes the injection tube 14. At this time, the piston 22 is no longer under pressure. Under the reaction force of the spring 23, the piston 22 is pulled back into the stirring tube 11 to prevent the arc-shaped nozzle from being blocked.
