Description

Technical Field

[0001] This utility model relates to the field of melting equipment technology, and more specifically to a high-temperature melting device for non-ferrous metal powder. Background Technology

[0002] During the melting of non-ferrous metal powders, the liquid properties of the metal require that the molten metal in the melting pool maintain a uniform temperature and composition distribution. This is because the liquid physical properties and thermal conductivity of metals are relatively poor, and any non-uniformity in temperature or composition can affect the quality and stability of the final molten metal. Especially when melting non-ferrous metal powders, the problem of uneven stirring is particularly prominent, which may lead to the following issues:

[0003] 1. Large temperature fluctuations: If the molten metal in the melting pool is not uniformly stirred, some areas of the metal may overheat while other areas may remain at a lower temperature. Excessive temperature fluctuations not only affect the stability of the melting process but can also lead to localized condensation or overheating of the metal, and may even cause defects such as crystallization or porosity, ultimately affecting the physical properties and machinability of the metal.

[0004] 2. Uneven composition distribution: Different components of a metal must be uniformly mixed during the melting process. Uneven mixing can lead to excessively high concentrations of certain elements in the molten metal, while other areas may have excessively low concentrations, resulting in inconsistent composition of the metal alloy. This uneven composition distribution not only affects the metal's strength, hardness, and other mechanical properties, but may also cause problems in subsequent processing, such as casting defects or unstable material properties.

[0005] 3. Low alloying efficiency: Alloying is an indispensable part of the high-temperature melting process. Metal powders often need to be alloyed with other metal elements during melting. Uneven stirring will reduce alloying efficiency, making it impossible to accurately control the alloy composition, which in turn affects the performance of the molten metal and its subsequent applications.

[0006] 4. Reduced melting efficiency: Due to uneven stirring, some metals may not be completely melted or stirred to the appropriate temperature. This not only affects the efficiency of the melting process, but also leads to longer heating time or higher energy consumption.

[0007] Therefore, there is an urgent need for a new type of high-temperature melting machine for non-ferrous metal powders that can ensure the uniformity of temperature and composition of molten metal during the melting process by optimizing the stirring mechanism, thereby further improving melting efficiency and metal quality and solving the problem of uneven stirring in traditional equipment. Utility Model Content

[0008] To address the aforementioned issues, this invention provides a high-temperature melting device for non-ferrous metal powders. By optimizing the stirring mechanism and insulation system, it effectively solves the problems of traditional equipment in terms of stirring, temperature uniformity, and metal oxidation, thereby improving melting efficiency and stability, and ensuring the quality of the metal.

[0009] To achieve the above objectives, this utility model provides the following technical solution, mainly including:

[0010] A high-temperature melting device for non-ferrous metal powder includes the following key components:

[0011] Support: The external structure of the melter is equipped with a support to support the entire high-temperature melter, ensuring the stability of the equipment and operational safety.

[0012] Heating Chamber: The heating chamber is the core component of the melter, containing highly efficient heating elements that can rapidly increase the temperature through electromagnetic induction or resistance heating. The heating chamber is supported by a bracket to ensure stable operation under high-temperature conditions.

[0013] Sealing cover and heat insulation cover: A sealing cover is installed above the heating chamber, and a heat insulation cover is installed at the lower end of the sealing cover. A certain gap is formed between the heat insulation cover and the sealing cover, and the gap is filled with an insulating layer to effectively prevent heat loss and improve heating efficiency. A feed inlet is provided on the upper side of the sealing cover. The feed inlet is funnel-shaped to facilitate the rapid entry of metal powder into the heating chamber.

[0014] Melting Pool: A melting pool is installed inside the heating chamber to hold metal powder and heat it to a molten state. A through channel is located at the center of the melting pool for installing a ring-shaped stirring mechanism. The inner wall of the melting pool is made of high-temperature resistant material, capable of withstanding the working pressure under high-temperature environments.

[0015] Annular stirring mechanism: The annular stirring mechanism is a key innovation of this utility model, ensuring the uniformity of metal powder during the melting process. This stirring mechanism includes components such as a motor, rotating shaft, heat insulation sleeve, rotating arm, internal gear ring, gears, and a stirrer.

[0016] Motor and rotating shaft: A motor is installed at the lower end of the heating chamber. The motor drives the rotating shaft through the output shaft. The rotating shaft passes through the channel in the center of the melting pool and drives the operation of the entire stirring system.

[0017] Heat insulation sleeve: A heat insulation sleeve is installed between the shaft and the central channel of the melting pool to prevent heat from being conducted to the shaft, thereby protecting the shaft and motor from high temperature.

[0018] Rotating arm and stirrer: A rotating arm is located at the upper end of the rotating shaft, and the far end of the rotating arm is connected to the stirrer. A gear is installed at the upper end of the stirrer, which meshes with an internal gear ring to achieve the rotation of the stirrer.

[0019] Internal gear ring and gear: An internal gear ring is located on the underside of the sealing cover, meshing with a gear on the rotating arm. When the motor starts and drives the shaft to rotate, the meshing of the gear and the internal gear ring drives the stirrer to rotate, thereby uniformly stirring the molten metal in the molten pool.

[0020] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. Improved temperature uniformity: The molten metal in the melting pool is uniformly stirred by a ring-shaped stirring mechanism, eliminating local overheating or undercooling and ensuring the consistency of the molten metal temperature during the melting process.

[0022] 2. Reduce metal oxidation: The design of the sealing cover and heat insulation cover effectively isolates oxygen in the air, reduces the risk of metal oxidation, and improves the purity and quality of the metal.

[0023] 3. Improve alloying efficiency: Uniform stirring allows elements in the molten metal to mix better, improving the efficiency of the alloying process and ensuring the stability of the molten metal composition.

[0024] 4. Improve melting efficiency: Uniform stirring of molten metal not only ensures uniform temperature but also shortens melting time, reduces energy consumption, and improves overall melting efficiency.

[0025] 5. Extend equipment life: The heat insulation sleeve design effectively blocks the impact of high temperature on the rotating shaft, reduces thermal fatigue of the equipment, and thus extends the service life of the melter. Attached Figure Description

The following description, in conjunction with the appendix... Figure 1-3 The specific embodiments of this utility model are described in detail below:

[0034] 1. Bracket 1:

[0035] Support bracket 1 is located on the outside of the entire high-temperature melter, and its main function is to support heating chamber 2 and other related components. Support bracket 1 is made of high-strength steel, capable of withstanding the thermal expansion and mechanical stress of the high-temperature melter during operation. The design of the support bracket not only ensures the stability of the melter but also facilitates the installation and transportation of the equipment.

[0036] The support frame 1 is fixed to the heating chamber 2 by welding or bolting, supporting its weight and providing a solid foundation for the equipment. The bottom of the support frame is equipped with a shock absorption device, which can effectively absorb the vibration generated during the operation of the equipment, ensuring that the melter will not shift or become unstable due to vibration during operation.

[0037] 2. Heating chamber 2:

[0038] Heating chamber 2 is one of the core components of the entire melting unit, primarily used to contain non-ferrous metal powder and provide the high-temperature environment required for melting the metal. The outer shell of heating chamber 2 is made of high-temperature resistant steel or alloy materials, capable of withstanding the pressure of prolonged high-temperature operation. To improve heating efficiency and extend the service life of heating chamber 2, the inner wall is coated with heat-resistant material.

[0039] Heating chamber 2 is equipped with heating elements such as electric heating tubes and electromagnetic heaters, which can provide uniform heat and ensure stable temperature during the melting process. The temperature control system includes temperature sensors and an automatic adjustment and control system, which can monitor the temperature changes inside heating chamber 2 in real time to ensure that the heating temperature is always kept within the set range.

[0040] 3. Sealing cover 3 and heat insulation cover 301:

[0041] The sealing cover 3 is located above the heating chamber 2, and its main function is to seal the heating chamber 2 and prevent heat from escaping during the melting process. A heat insulation cover 301 is provided at the lower end of the sealing cover 3, and an insulation layer 302 is provided between the heat insulation cover 301 and the sealing cover 3. This design not only effectively isolates heat loss but also prevents external air from contacting the molten metal, thereby reducing the risk of metal oxidation.

[0042] The sealing cover 3 is designed with high-temperature heat-resistant materials to ensure its long-term stable operation in high-temperature environments. The heat insulation cover 301 can further reduce heat loss, reduce equipment energy consumption, and help maintain a stable temperature within the melting pool 5.

[0043] 4. Feed inlet 4:

[0044] A funnel-shaped feed inlet 4 is provided on the upper side of the sealing cover 3 to facilitate the accurate and uniform entry of metal powder into the heating chamber 2. The funnel design of the feed inlet 4 allows the powdered metal material to flow quickly into the melting pool 5 and enter the heating chamber 2 by gravity, ensuring uniform distribution of the metal material during the melting process. A filter device can also be installed at the feed inlet 4 to filter out any large particles of impurities, ensuring high purity of the metal powder entering the heating chamber 2 and preventing impurities from affecting the melting process and subsequent processing.

[0045] The feed inlet 4 is reasonably designed to accommodate different types of metal powders, effectively avoiding blockage or jamming during feeding.

[0046] 5. Melting pool 5 and channel:

[0047] Heating chamber 2 contains a melting pool 5, which is the area where the metal powder is actually melted. The melting pool 5 is made of high-strength refractory material, capable of withstanding extremely high temperatures and not easily undergoing chemical reactions. A slag discharge port or a liquid discharge port can be installed at the bottom of the melting pool 5 to discharge impurities or excess molten metal generated during the melting process.

[0048] A through channel is provided in the center of the melting pool 5 for the passage of the annular stirring mechanism 6. This channel design ensures that the stirring mechanism can accurately pass through the center of the melting pool 5 and perform effective stirring. The uniformity of temperature distribution and the fluidity of the molten metal within the melting pool 5 depend to some extent on the effectiveness of the stirring mechanism; therefore, this part of the design is particularly critical.

[0049] 6. Circular stirring mechanism 6:

[0050] The annular stirring mechanism 6 is one of the key technologies of this utility model, mainly including a motor 6, a rotating shaft 601, a heat insulation sleeve 602, a rotating arm 603, an internal gear ring 604, a gear 605, and a stirrer 606. The annular stirring mechanism 6 drives the stirrer 606 to rotate by the rotation of the rotating shaft 601, thereby achieving uniform stirring of the molten metal.

[0051] Motor 6: Motor 6 is a high-efficiency motor that can precisely adjust the speed of the rotating shaft 601, ensuring that the agitator 606 can uniformly stir the molten metal at the set speed. Motor 6 is connected to the rotating shaft 601, providing the necessary power output to ensure that the rotating arm 603 and the agitator 606 can work efficiently.

[0052] Rotating shaft 601 and heat insulation sleeve 602: The rotating shaft 601 passes through the channel in the center of the melting pool 5, and a heat insulation sleeve 602 is provided between the rotating shaft 601 and the melting pool 5.
