[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: an argon dehydrogenation device for molten aluminum, including an argon dehydrogenation device body 1, an argon cylinder 2 is provided on one side of the argon dehydrogenation device body 1, a connecting pipe 3 is connected to the top of the argon cylinder 2, a first control valve 4 is connected to one end of the connecting pipe 3, a heating component is connected to one end of the first control valve 4, a second control valve 5 is provided on one side of the heating component, a gas pump 6 is connected to one end of the second control valve 5, a delivery pipe 7 is connected to the output end of the gas pump 6, one end of the delivery pipe 7 passes through the argon dehydrogenation device body 1 and is connected to a diversion pipe 8, anti-corrosion pipes 9 are connected to both ends of one side of the diversion pipe 8, and multiple nozzles 10 are evenly distributed on the outer side of the anti-corrosion pipes 9.

[0022] In this embodiment, a fixed amount of argon gas can be stored in argon cylinder 2. The first control valve 4 controls the argon gas in argon cylinder 2 to enter the heating assembly through the connecting pipe 3. The heating assembly heats the argon gas, while the second control valve 5 prevents leakage of argon gas during the heating process. The gas pump 6 can extract the heated argon gas from the heating assembly and deliver it through the delivery pipe 7 to the diversion pipe 8 and then to the anti-corrosion pipe 9. Multiple nozzles 10 spray the argon gas to ensure full contact between the argon gas and the aluminum liquid, thereby increasing the range of bubble action, improving overall working efficiency, increasing argon gas utilization, and meeting actual usage requirements.

[0023] Example 2: As Figures 1-4 As shown, the heating assembly includes a heating box 11, with three electric heating rods 12 on the top of the heating box 11. The heating ends of the three electric heating rods 12 are inserted into the interior of the heating box 11. A motor 13 is installed on the top of the argon dehydrogenation device body 1. The output end of the motor 13 passes through the argon dehydrogenation device body 1 and is connected to a stirring shaft 14. Multiple stirring paddles 15 are installed on the outside of the stirring shaft 14. Mounting brackets 16 are symmetrically arranged at both ends of the bottom of the argon dehydrogenation device body 1. Electric heating plates 17 are installed on the top of the two mounting brackets 16. An inlet 18 is installed at one end of the argon dehydrogenation device body 1. A third control valve 19 is installed at the bottom of one end of the argon dehydrogenation device body 1. One end of the third control valve 19 is connected to an outlet 20. Legs 21 are installed at the four corners of the bottom of the argon dehydrogenation device body 1. Anti-slip pads 22 are installed on the bottom of the legs 21.

[0024] In this embodiment, a portion of the argon gas can be temporarily stored in the heating box 11. The argon gas inside the heating box 11 is heated by the electric heating rod 12, bringing its temperature closer to that of the molten aluminum. This reduces the temperature difference between the argon gas and the molten aluminum, thereby accelerating the bubble-forming process and further improving efficiency. The stirring shaft 14, driven by the motor 13, rotates the stirring paddle 15, stirring the molten aluminum in the argon dehydrogenation device body 1. This further accelerates the bubble-forming process between the argon gas and the molten aluminum, further improving the utilization rate of the argon gas. (The last sentence appears to be incomplete and possibly refers to a different embodiment.) 16 allows the electric heating plate 17 to be attached to the bottom of the argon dehydrogenation device body 1, and the electric heating plate 17 is used to heat the aluminum liquid inside the argon dehydrogenation device body 1 to maintain a relatively stable temperature. The aluminum liquid can be added into the argon dehydrogenation device body 1 through the feed port 18, and the dehydrogenated aluminum liquid can be discharged from the discharge port 20 through the third control valve 19. The foot bracket 21 can provide stable support for the argon dehydrogenation device body 1, and the anti-slip pad 22 can increase the friction and prevent the argon dehydrogenation device body 1 from shaking.

[0025] The working principle of the embodiment is as follows: in use, first, the molten aluminum is added into the argon hydrogen removal device body 1 from the feeding port 18, and the molten aluminum is heated by the electric heating plate 17 to maintain a relatively stable temperature, then the first control valve 4 is opened, the argon stored in the argon cylinder 2 is introduced into the heating box 11 through the connecting pipe 3, the argon is heated by the electric heating rod 12 to be heated to a temperature close to that of the molten aluminum, then the second control valve 5 is opened and the air pump 6 is started, the heated argon is pumped out from the heating box 11 and is transported to the shunt pipe 8 through the conveying pipe 7, the argon is shunted to the two corrosion-resistant pipes 9 through the shunt pipe 8, and the argon is sprayed to the molten aluminum in the argon hydrogen removal device body 1 through the plurality of nozzles 10, at the same time, the motor 13 is started to drive the stirring shaft 14 to drive the stirring paddle 15 to stir the molten aluminum, so that the argon is rapidly contacted with the molten aluminum and the gas bubble effect is generated to remove the hydrogen in the molten aluminum, finally, the third control valve 19 is opened, the molten aluminum after hydrogen removal is discharged from the discharging port 20, so that the use of the argon hydrogen removal device for molten aluminum is completed.

[0026] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments still fall within the protection scope of the present application.
