Description

Technical Field

[0001] This utility model relates to the technical field of aluminum liquid treatment equipment, and in particular to an ultrasonic purification device for high-purity aluminum liquid. Background Technology

[0002] Aluminum and its alloys are widely used in aerospace, automotive manufacturing, construction, and other fields. However, during the production of molten aluminum, impurities such as hydrogen and oxides may appear. If these impurities are not treated, they will seriously affect the mechanical and processing properties of the material. Hydrogen will cause porosity within the material, reducing its strength and shortening its fatigue life, while oxides will cause stress concentration and reduce its ductility. Existing purification equipment mostly uses inert gases to remove hydrogen and oxides, which can ensure purification effects, but the purification efficiency is not high. Utility Model Content

[0003] The purpose of this invention is to provide an ultrasonic purification device for high-purity aluminum liquid. This device utilizes ultrasonic vibration to accelerate the diffusion rate of inert gas, enabling the inert gas bubbles to quickly adsorb hydrogen and oxides, thereby improving purification efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-purity aluminum liquid ultrasonic purification device, comprising a lifting mechanism and an aluminum liquid tank. The lifting mechanism includes a fixed frame, a lifting frame vertically slidably connected to the fixed frame, a cylinder installed between the lifting frame and the fixed frame, a servo motor fixedly connected to the lifting frame, the output shaft of the servo motor being vertically downward and fixedly connected to a mounting plate, an ultrasonic generator and a ventilation pipe being installed at the bottom of the mounting plate; an aluminum liquid inlet is provided at the upper part of the aluminum liquid tank, and an aluminum liquid outlet is provided at the lower part of the aluminum liquid tank.

[0005] Optionally, a reel is fixedly connected to the output shaft of the servo motor. The reel has wire holes on both sides. The lifting frame has two through holes, in which an electric wire and a gas hose are placed respectively. The electric wire passes through the wire hole and connects to the ultrasonic generator, and the gas hose passes through the wire hole and connects to the ventilation pipe.

[0006] Optionally, the ventilation pipeline includes a main gas transmission pipeline and several branch gas pipelines, with the main gas transmission pipeline installed vertically and the branch gas pipelines evenly distributed at the bottom of the main gas transmission pipeline.

[0007] Optionally, the mounting plate is larger than the opening of the molten aluminum tank, and an air vent is provided at the top of the molten aluminum tank.

[0008] Optionally, a sealing gasket is provided on the bottom of the mounting plate.

[0009] The ultrasonic purification device for high-purity aluminum liquid of this invention has the following advantages:

[0010] (1) Inert gas is introduced into the aluminum liquid tank through the ventilation pipe. The ultrasonic generator generates high-frequency mechanical vibration, which breaks the bubbles of inert gas into micron-sized bubbles, allowing the bubbles to diffuse rapidly and adsorb hydrogen and oxides in the aluminum liquid. At the same time, the high-frequency vibration can also induce cavitation effect, break dendrites and promote bubble floating, further improving the purification efficiency.

[0011] (2) The servo motor can drive the mounting plate to rotate 180° clockwise and counterclockwise, so that the inert gas is evenly filled into the aluminum liquid. The ultrasonic generator can also uniformly vibrate and diffuse the inert gas, thereby improving the purification effect of the bubbles.

[0012] (3) The mounting plate is placed on the top of the aluminum liquid tank to provide a certain sealing effect. After the bubbles rise from the aluminum liquid and are released, they are discharged from the air outlet and collected. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, an ultrasonic purification device for high-purity molten aluminum includes a lifting mechanism and an aluminum liquid tank 1. The upper part of the aluminum liquid tank 1 has an aluminum liquid inlet 2, and the lower part has an aluminum liquid outlet 3. The lifting mechanism includes a fixed frame 4, on which a lifting frame 5 is vertically slidably connected. A cylinder is installed between the lifting frame 5 and the fixed frame 4, and the cylinder drives the lifting frame 5 to move vertically. A servo motor 6 is fixedly connected to the lifting frame 5. The output shaft of the servo motor 6 is vertically downward and fixedly connected to a mounting plate 7. An ultrasonic generator 8 and a ventilation pipe are installed at the bottom of the mounting plate 7. A winding reel 9 is also fixedly connected to the output shaft of the servo motor 6. Wire holes are opened on both sides of the winding reel 9, which is located between the lifting frame 5 and the mounting frame. The lifting frame 5 has two through holes, in which an electric wire 10 and a gas hose 11 are respectively placed. The electric wire 10 passes through the through hole and connects to the ultrasonic generator 8, while the gas hose 11 passes through the through hole and connects to the ventilation pipe. The electric wire 10 and the gas hose 11 are arranged in a crisscross pattern to provide sufficient space for the retraction and extension of the pipelines. The servo motor 6 can drive the mounting frame to rotate 180° clockwise and counterclockwise, allowing the ultrasonic generator 8 and the ventilation pipe to cover the entire aluminum liquid tank 1. When the mounting frame rotates, the electric wire 10 and the gas hose 11 can be retracted and extended on the reel 9, preventing the pipelines from becoming tangled or pulled.

[0016] The size of the mounting plate 7 is larger than the opening size of the aluminum liquid tank 1. A sealing gasket 12 is provided at the bottom of the mounting plate 7. When the lifting frame 5 lowers the mounting plate 7 to the top of the aluminum liquid tank 1, the mounting plate 7 can play a certain sealing role. An air outlet 13 is provided at the top of the aluminum liquid tank 1 to collect the gas overflowing from the aluminum liquid. The collected gas can be reused after separation, saving costs.

[0017] The ventilation system includes a main gas supply pipe 14 and several branch gas pipes 15. The main gas supply pipe 14 is vertically arranged, and the branch gas pipes 15 are evenly arranged in a circular structure at the bottom of the main gas supply pipe 14. Nitrogen gas enters the ventilation system through a gas hose 11 and then is rapidly injected into the molten aluminum through the branch gas pipes 15. A protective cover 16 is installed on the outside of the branch gas pipes 15 to improve their stability. Simultaneously, the ultrasonic generator 8 generates high-frequency mechanical vibrations, breaking the nitrogen bubbles into micron-sized bubbles. These bubbles rapidly diffuse and adsorb hydrogen and oxides from the molten aluminum. The high-frequency vibrations also induce cavitation, breaking dendrites and promoting bubble bubbling. The servo motor 6 can drive the mounting bracket to rotate 360°, ensuring that the nitrogen gas and vibration cover the entire molten aluminum tank 1, improving the purification effect.

[0018] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
