Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, specifically to a portable degassing device for aluminum and aluminum alloy melts. Background Technology

[0002] Aluminum and aluminum alloys, as lightweight and high-strength metallic materials, are widely used in many fields such as aviation, aerospace, construction, automotive, rail transportation, shipbuilding, machinery manufacturing, power, electronics, instrumentation, chemical industry, building decoration, packaging, and sporting goods. Their excellent physical and mechanical properties, as well as good corrosion resistance, make aluminum and aluminum alloys indispensable materials in modern industry.

[0003] However, during the production of aluminum and aluminum alloys, impurities such as gases (e.g., hydrogen) and inclusions (e.g., oxides, nitrides) are often introduced into the melt. The presence of these impurities severely affects the mechanical properties, processing performance, and corrosion resistance of the material, reducing product quality and reliability, and even leading to an increase in scrap rates. Therefore, the purification treatment of aluminum alloy melts has become a crucial step in the aluminum alloy production process.

[0004] Currently, there are various methods for purifying molten aluminum alloys, including gas purification, flux purification, filtration purification, vacuum purification, electromagnetic purification, ultrasonic purification, and combined purification. Among these, inert gas purification methods are widely used due to their advantages such as high efficiency, environmental friendliness, and ease of control.

[0005] Among inert gas purification methods, SNIF and ALPUR are two commonly used industrial technologies. They purify the melt by introducing an inert gas (such as argon) into it, utilizing the buoyancy and agitation of the bubbles to remove gases and inclusions. However, both methods are suitable for continuous online processing of aluminum alloy melts, handling large volumes, requiring complex and costly equipment, and are not portable, making them unsuitable for small-batch laboratory or intermittent small-batch production.

[0006] To address this issue, it is particularly important to develop a portable, efficient, and economical degassing device for aluminum and aluminum alloy melts. Utility Model Content

Detailed Implementation

[0033] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] Example 1

[0035] A portable degassing device for molten aluminum and aluminum alloys, as shown in the attached document. Figure 1-4As shown in Figure 9, the enclosure includes a housing 1. Two fixing plates 2 are symmetrically fixed at one end of the housing 1 (the number of fixing plates 2 can be determined according to actual needs; in this embodiment, two plates are used to better limit and fix the gas cylinder 23). Two fixing holes 20 are symmetrically opened on the fixing plates. Two gas cylinders 23 are installed on one end of the bottom inner wall of the housing 1 via the two symmetrical fixing plates 2. One gas cylinder 23 serves as a spare gas cylinder 23. The use of one gas cylinder in use and one in reserve allows for continuous gas supply. These two gas cylinders 23 are respectively engaged in the symmetrically opened fixing holes 20 on the fixing plates 2 for storing inert gas. (e.g., argon); the other end is fixed with two lifting rods 3 (the number of lifting rods 3 can be determined according to the specific production situation). Here, an electric push rod 22 is used. The top of the lifting rod 3 is fixedly connected to a support rod 4. The support rod 4 is rotatably connected to a storage rod 6 by bolts 5. The storage rod 6 is fixed to the support rod 4 by pin I 7, and can also be fixed to the support rod 4 by pin II 8. The end of the storage rod 6 away from the bolt 5 is fixedly connected to a degassing component. The storage rod 6 is designed to facilitate the storage of the degassing component when not in use, saving space. The degassing component is connected to one of the gas cylinders 23 through a gas pipe 9.

[0036] The degassing assembly includes a gas supply chamber 10, within which a gas cylinder 11 is fixedly connected for receiving inert gas from a gas cylinder 23. The gas cylinder 11 is connected to a gas pipe 9, and a gas supply rod 12 is rotatably connected to the gas cylinder 11. The gas supply rod 12 extends out of the gas supply chamber 10 and is rotatably connected to it. A nozzle 13 is fixedly connected to one end of the rod extending out of the gas supply chamber 10. The nozzle 13 is a graphite nozzle, with an outlet hole I 17 at its bottom and a bevel 18 at its bottom. Several nozzles are evenly distributed along the bevel 18. The air outlet II19 is designed to allow inert gas to be sprayed more evenly into the molten aluminum alloy, improving the degassing effect. The air supply rod 12 is located inside the air supply chamber 10 and is fixedly sleeved with gear I14. A rotary motor 15 is fixedly installed on one side of the air supply chamber 10. The output end of the rotary motor 15 is fixedly connected to gear II16. Gear II16 meshes with gear I14. By starting the rotary motor 15, the air supply rod 12 can be driven to rotate in the air cylinder 11 and the air supply chamber 10, thereby driving the nozzle 13 to rotate and achieving all-round degassing of the molten aluminum alloy.

[0037] Furthermore, to facilitate the movement of the device, four omnidirectional wheels 21 are symmetrically fixed to the bottom of the housing 1. These self-locking omnidirectional wheels lock in place during operation to maintain the stability of the device. To facilitate pushing the device when needed, a push rod 22 is rotatably connected to one side of the outer wall of the housing 1. A locking block 24 is fixed to the outer wall of the housing 1 on the same side as the push rod 22. The push rod 22 is locked to the outer wall of the housing 1 by the locking block 24, thus storing the push rod 22.

[0038] Working principle

[0039] In use, first move the device to the vicinity of the aluminum alloy molten material that needs to be degassed, lock the casters 21, and then adjust the height of the degassed component using the lifting rod 3. Next, pull out the pin II 8 and rotate the storage rod 6 to fix it to the support rod 4 using the pin I 7. Then, adjust the height of the nozzle 13 using the lifting rod 3 to maintain an appropriate distance from the surface of the molten material. Next, start the rotary motor 15 to make the nozzle 13 start rotating and open the valve of the gas cylinder 23. The inert gas will enter the gas cylinder 11 through the gas pipe 9 and then be evenly sprayed into the aluminum alloy molten material through the nozzle 13 to achieve degassed material. After degassed material is degassed, close the valve of the gas cylinder 23, stop the rotary motor 15, and store the degassed component using the storage rod 6. During this process, the lifting rod 3 is used to raise and lower the device to a suitable height to assist in storage. Then, push the device to the next working location.

[0040] Example 2

[0041] Further details are attached. Figure 5-8 As shown, to more stably fix the gas cylinder 23 and prevent positional displacement of the gas cylinder 23 during movement or operation, the difference from Embodiment 1 is as follows: a partition 25 is fixedly provided in the middle of the lower fixing plate 2, and clamping assemblies are symmetrically arranged along the partition 25 on the lower fixing plate 2. The clamping assembly includes a bracket 26, which is slidably connected to the top of the lower fixing plate 2. A spring I 27 is fixedly connected to one end of the bracket 26, and one end of the spring I 27 is fixedly connected to the lower fixing plate 2. A clamping block I 28 is fixedly connected to one side of the bracket 26, and a clamping block II 29 is slidably connected to the lower fixing plate 2. A spring II 30 is fixedly provided at one end of the clamping block II 29. One end of clamping block 20 is fixedly connected to partition plate 25. Clamping block II 29 is rotatably connected to bracket 26 via connecting rod 31. Clamping block I 28 and clamping block II 29 respectively abut against both sides of one of the gas cylinders 23 to clamp and fix the gas cylinder 23. The upper fixing plate 2 has a through groove 32. A connecting plate 33 is fixedly connected to bracket 26 below the through groove 32. The connecting plate 33 extends out of the upper fixing plate 2. A handle 34 is fixedly connected to one end of the connecting plate 33 extending out of the upper fixing plate 2 to facilitate manual operation of the clamping assembly. A cover plate 35 is provided above the clamping assembly. The cover plate 35 limits the clamping assembly to ensure that the function of the clamping assembly can be realized smoothly.

[0042] In this embodiment, when it is necessary to replace the gas cylinder 23, the handles 34 can be pulled in a direction away from each other. At this time, the bracket 26 and the connecting rod 31 respectively pull the clamping block I 28 and the clamping block II 29 to move away from each other. The clamping assembly loosens its clamping and fixing of the gas cylinder 23. At this time, the gas cylinder 23 is lifted upward and the new gas cylinder 23 is placed into the fixing hole 20 of the fixing plate 2. The handles 34 are released, and the springs I 27 and II 30 are reset, thereby realizing the re-clamping and fixing of the gas cylinder 23 by the clamping assembly.
