Description

Technical Field

[0001] This utility model relates to the field of refining equipment technology, and in particular to a metal alloy refining equipment. Background Technology

[0002] Metal alloy refining refers to the process of removing harmful impurities (such as gases, non-metallic inclusions, and harmful metallic elements) from metal alloys through a series of physical, chemical, or metallurgical processes, adjusting the alloy composition to a target range, and improving the internal structure and properties of the alloy, thereby obtaining alloy materials with higher purity and better performance. Refining can remove impurities such as hydrogen (which causes hydrogen embrittlement), oxygen (which forms oxides), and nitrogen (which affects toughness). It can also remove oxides, sulfides, silicates, etc. (which reduce the alloy's strength, plasticity, and corrosion resistance), lead, tin (which affects the hot brittleness of steel), and phosphorus (which causes cold brittleness).

[0003] In existing technologies, refining agents are required when refining metal alloys (e.g., aluminum alloy refining agents, which are usually white powders or granules, composed of a mixture of various inorganic salts, some of which contain organic compounds, mainly used for degassing (such as hydrogen) and removing slag (such as oxide inclusions), while improving the fluidity of molten aluminum). The refining agent is added and mixed evenly with the melt, and then left to stand for a period of time to allow impurities to fully react and float to the surface, thereby achieving the refining effect. However, in existing technologies, it is impossible to control the amount of refining agent added, resulting in inaccurate dosage and incomplete purification. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1 to 4 A metal alloy refining apparatus includes a refining furnace body 1, a feed pipe 2 installed above the refining furnace body 1, and a feeding device provided above the refining furnace body 1.

[0029] The feeding device is equipped with:

[0030] The rotating feeding component has a discharge trough 10 on its surface for receiving refining agent (powder or granules);

[0031] A quantitative limiting component is located on one side of the rotating feeding component;

[0032] When the rotary feeding component rotates to the position corresponding to the quantitative limiting component, the quantitative limiting component scrapes off the excess refining agent in the discharge trough 10 that exceeds the preset amount, so as to limit the amount of refining agent in the discharge trough 10; when the rotary feeding component continues to rotate to the lower position, the refining agent in the discharge trough 10 is fed into the feed pipe 2.

[0033] In use, this device employs a feeding system consisting of a rotating feeder and a quantitative limiting device, positioned above the refining furnace body 1. The discharge trough 10 on the surface of the rotating feeder accommodates the refining agent, while the quantitative limiting device scrapes away excess refining agent during rotation. This achieves precise quantitative feeding of the refining agent, effectively avoiding the quantity discrepancies that easily occur with manual feeding and ensuring the consistency of the refining agent input for each batch. This improves the stability of the refining quality of the metal alloy. The feeding device directly feeds the quantitatively measured refining agent into the feed pipe 2, allowing the refining agent to quickly enter the refining furnace body 1. This reduces the spillage and loss of the refining agent during the feeding process, lowers raw material waste, and avoids pollution caused by excess refining agent accumulating inside the device.

[0034] Furthermore, brackets 3 are installed on both sides of the top of the refining furnace body 1, and the feeding device is set on the brackets 3. The brackets 3 provide stable installation support for the feeding device, so that the feeding device can be firmly in the working position, avoiding the impact of device shaking on the feeding accuracy during the rotating feeding process, and ensuring the stability of the feeding device operation.

[0035] Furthermore, each of the two brackets 3 has a slot 4 at its top, and L-shaped connectors 5 are provided on both sides of the feeding device. The connectors 5 are movably inserted into the corresponding slots 4 and can be secured within the slots 4 by bolts or friction. This movable connection between the connectors 5 and the slots 4 facilitates the installation and disassembly of the feeding device. When the feeding device needs inspection, maintenance, or replacement, it can be easily removed from the brackets 3, making the operation simple and quick, reducing the difficulty and cost of equipment maintenance. At the same time, the plug-in structure ensures the connection stability of the feeding device during operation.

[0036] Furthermore, the feeding device includes a discharge box body 7, with an installation groove 8 on the top of the discharge box body 7 extending from the top to the bottom. The rotating feeding component and the quantitative limiting component are both disposed within the installation groove 8. The installation groove 8 extends from the top to the bottom through the discharge box body 7. The rotating feeding component includes a feeding cylinder 9 rotatably disposed within the installation groove 8 and a rotary motor 16 disposed on one side of the discharge box body 7. The discharge groove 10 is located on the outer surface of the feeding cylinder 9. The drive end of the rotary motor 16 movably passes through the discharge box body 7 and is fixedly connected to one side of the feeding cylinder 9. The rotary motor 16 drives the feeding cylinder 9 to rotate. The discharge groove 10 on the outer surface of the feeding cylinder 9 can accommodate the refining agent. As the feeding cylinder 9 rotates, the process of material collection, quantitative measurement, and feeding is completed. The degree of automation is high, improving the feeding efficiency. Moreover, the driving method of the rotary motor 16 is stable and reliable, ensuring the continuity of the feeding process.

[0037] Furthermore, the discharge troughs 10 are provided in a plurality of them, and are arranged in a ring array on the outer surface of the feeding cylinder 9. The plurality of discharge troughs 10 arranged in a ring array enable the rotating feeding component to continuously perform feeding operations during rotation, thereby improving the frequency and efficiency of feeding. The design of multiple discharge troughs 10 can add more refining agent within a certain period of time (while ensuring the quantitative amount per trough), meeting the feeding speed requirements of different refining processes. At the same time, the ring array layout makes the feeding process more uniform and stable.

[0038] Furthermore, the quantitative limiting component includes two guide blocks 11 fixedly installed in the mounting groove 8, with a discharge port 12 formed between the two guide blocks 11. The feeding cylinder 9 is rotatably positioned at the discharge port 12. A limiting block 13 is provided on one side of the bottom end of each guide block 11. The limiting block 13 is in contact with the outer periphery of the feeding cylinder 9 and is used to scrape off excess refining agent exceeding the preset amount in the discharge trough 10 when the feeding cylinder 9 rotates to discharge material. The structure of the quantitative limiting component, with the discharge port 12 formed by the two guide blocks 11 providing limiting and guiding functions for the rotation of the feeding cylinder 9, and the limiting block 13 in contact with the outer periphery of the feeding cylinder 9, can accurately scrape off excess refining agent exceeding the preset amount in the discharge trough 10, further ensuring the accuracy of each feeding amount. This structural design is simple and effective, with high precision in quantitative control of the refining agent, ensuring the consistency of the refining effect of the metal alloy.

[0039] Furthermore, the feeding cylinder 9 is integrally molded from polyethylene. Polyethylene material has good chemical stability and wear resistance, and is not prone to chemical reaction with refining agents, thus ensuring the purity of the refining agents. Its smooth surface reduces the residue of refining agents in the discharge tank 10, while extending the service life of the feeding cylinder 9 and reducing the frequency of equipment replacement.

[0040] Furthermore, the discharge box body 7 is provided with two guide plates 14. The two guide plates 14 are inclinedly arranged inside the discharge box body 7 and are located below the feeding cylinder 9. They are used to guide the refining agent into the first feed inlet 6. Through the two inclined guide plates 14, the refining agent fed from the feeding cylinder 9 can be smoothly guided into the first feed inlet 6, avoiding the refining agent from scattering or accumulating in the discharge box body 7, ensuring the full utilization of the refining agent and reducing waste. The inclined design of the guide plates 14 uses gravity to guide the flow of the refining agent without the need for additional power, thus saving energy.

[0041] Furthermore, an inclined plate 15 is also provided inside the discharge box body 7. The inclined plate 15 is located above the feeding cylinder 9. By positioning the inclined plate 15 above the feeding cylinder 9, it can guide the refining agent fed into the discharge box body 7, so that the refining agent can flow accurately to the discharge trough 10 of the feeding cylinder 9, avoiding the accumulation of refining agent above the feeding cylinder 9 and affecting the normal operation of the feeding process, thereby improving the utilization rate of the refining agent and the smoothness of the feeding.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
