Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid transfer, and in particular to a forklift-type aluminum liquid transfer ladle. Background Technology

[0002] After the aluminum is melted in the aluminum melting furnace, the molten aluminum is transferred to the holding furnace. The holding furnace then conveys the high-temperature molten aluminum to the aluminum transfer ladle through a trough. The transfer ladle is a large ladle that transports molten metal. The aluminum molten metal direct supply transfer ladle is an important component of the aluminum molten metal direct supply system. Currently, aluminum molten metal transfer ladles are often transferred using forklifts. Forklift operators use forklifts to add the transfer ladles one by one to the holding furnace of the die-casting machine. However, in this process, the aluminum molten metal loses heat, creating a temperature difference with the temperature required by the production process.

[0003] To ensure that process requirements are met, forklift operators need to measure the temperature of the molten aluminum at regular intervals to ensure that the temperature meets the requirements. If the temperature does not meet the requirements, it needs to be heated by a special heater for the ladle. In the prior art, Chinese utility model patent with authorization announcement number CN 211135511 U provides a new type of molten aluminum transfer ladle, including a ladle body with an internal cavity. Two sets of identical heating components are arranged in the middle of the ladle body. The two sets of heating components are welded to the outer walls of the left and right sides of the ladle body respectively through flanges. The heating components are electric heating tubes.

[0004] Using the above technical solution, the aluminum liquid can be heated by the heating component without the need for external heating equipment. However, the heating speed of the electric heating tube is relatively slow. The aluminum liquid has a large specific heat capacity, and it takes a long time for the electric heating tube to complete the heating process, especially when processing a large amount of aluminum liquid. This greatly increases the transfer time of the ladle and affects the production efficiency of the blank. Utility Model Content

[0005] To address the technical problem of low heating rate of molten aluminum in the existing technology of transfer ladles, this invention provides a forklift-type molten aluminum transfer ladle, which can improve the heating rate of molten aluminum, shorten the time the ladle is occupied, and improve production efficiency.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a forklift-type aluminum liquid transfer ladle, including a ladle body, and further including: a refractory layer, the refractory layer being disposed on the inner wall of the ladle body, the refractory layer being made of silicon carbide; an induction heating component, the induction coil of the induction heating component being embedded inside the refractory layer, the induction coil being coaxially disposed with the refractory layer, and the power connector of the induction heating component being disposed on the ladle body.

[0007] This invention heats molten aluminum by embedding an induction heating component. It utilizes the principle of electromagnetic induction to generate heat directly inside the molten aluminum, eliminating the need for external heat conduction. Furthermore, the alternating magnetic field penetrates deep into the molten aluminum, causing it to heat up rapidly as a whole. The heating speed is much faster than that of an electric heating tube, allowing the molten aluminum to reach a higher temperature in a short time. Moreover, the eddy currents generated by the alternating magnetic field in the molten aluminum are relatively evenly distributed, resulting in a more uniform temperature distribution inside the molten aluminum.

[0008] Furthermore, it also includes a temperature detection component, which includes an electrically connected temperature sensor and a display. The temperature sensor is disposed inside the package body, and the display is disposed on the outer surface of the package body. It also includes a mobile power supply that is electrically connected to the induction heating component.

[0009] This invention, by adding a temperature detection component and a mobile power source, enables automatic heating when the temperature of the molten aluminum is lower than the set temperature, eliminating the need for manual temperature measurement and heating at a fixed location. This extends the heat preservation time of the transfer ladle, making it more flexible and suitable for long-distance transportation.

[0010] Furthermore, the induction heating component employs medium-frequency induction heating.

[0011] This invention utilizes medium-frequency induction heating to achieve more uniform temperature changes throughout the molten aluminum, thereby improving the uniformity of the temperature field and enhancing product quality.

[0012] Furthermore, the package includes an energy storage layer, which is adjacent to and located outside the refractory layer, and the energy storage layer is made of a high-temperature phase change material.

[0013] This invention utilizes a high-temperature phase change material to store the energy lost by molten aluminum at high temperatures and release the absorbed energy at low temperatures, thus preventing excessive heat loss from the molten aluminum to the outside world and avoiding significant temperature changes, which helps to shorten the heating time.

[0014] Furthermore, the package also includes a thermal insulation layer located outside the energy storage layer, and the thermal insulation layer is made of fire-resistant asbestos.

[0015] This invention reduces heat loss from molten aluminum by incorporating an insulation layer.

[0016] Furthermore, the package also includes an insulating layer disposed outside the insulation layer, and the insulating layer is made of ceramic fiber material.

[0017] This invention provides a heat-preventing effect by setting an insulating layer, thereby improving safety during use.

[0018] Furthermore, a vacuum interlayer is provided between the insulation layer and the energy storage layer.

[0019] This invention further enhances the heat preservation effect on molten aluminum by setting up a vacuum interlayer.

[0020] Furthermore, aluminum foil is provided on the surface of the insulation layer opposite to the energy storage layer.

[0021] This invention uses aluminum foil to reflect heat radiation, which greatly reduces the amount of heat radiation from the molten aluminum, thus achieving a heat preservation effect.

[0022] Furthermore, both the package and the cavity of the refractory layer have an ellipsoidal structure.

[0023] This invention, by setting the cavity of the ladle and the refractory layer as an ellipsoidal structure, can reduce the contact area between the molten aluminum and the inner wall of the transfer ladle within the same volume, thereby further reducing heat loss.

[0024] Furthermore, it also includes a cover, which is connected to the bag body via a hinge assembly.

[0025] As can be seen from the above technical solutions, this utility model has the following advantages:

[0026] This invention provides a forklift-type aluminum molten transfer ladle. It utilizes an embedded induction heating component to heat the aluminum molten metal using electromagnetic induction. Heat is generated directly within the molten metal, eliminating the need for external heat conduction. The alternating magnetic field penetrates deep into the molten metal, causing rapid heating throughout, much faster than electric heating elements. This allows the molten metal to reach a high temperature quickly. Furthermore, the eddy currents generated by the alternating magnetic field within the molten metal are relatively evenly distributed, resulting in a more uniform internal temperature distribution. By adding a temperature detection component and a mobile power supply, automatic heating can be initiated when the molten metal temperature falls below a set temperature, eliminating the need for manual temperature measurement and heating at a fixed location. This extends the holding time of the ladle, making it flexible and suitable for long-distance transport. The use of medium-frequency induction heating ensures consistent temperature throughout the molten metal. The temperature variation is more uniform, improving the uniformity of the aluminum liquid temperature field and enhancing product quality. The use of high-temperature phase change materials stores energy lost from the aluminum liquid at high temperatures and releases absorbed energy at low temperatures, preventing excessive heat loss and significant temperature fluctuations, thus shortening heating time. An insulation layer reduces heat loss from the aluminum liquid. An insulating layer prevents scalding and improves safety. A vacuum interlayer further enhances insulation. Aluminum foil reflects heat radiation, significantly reducing heat radiation and providing insulation. An ellipsoidal structure for the ladle and refractory layer, compared to a cylindrical structure, reduces the contact area between the aluminum liquid and the inner wall of the ladle within the same volume, further minimizing heat loss.

[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0032] like Figure 1 and Figure 2 As shown in the figure, this specific embodiment provides a forklift-type aluminum molten transfer ladle, including a ladle body 1, a refractory layer 8, and an induction heating component. The refractory layer 8 is disposed on the inner wall of the ladle body 1. The refractory layer 8 is made of silicon carbide, which has minimal impact on the magnetic field and excellent corrosion resistance and high mechanical strength. To avoid adverse effects from the aluminum molten material, the induction coil 9 of the induction heating component is embedded inside the refractory layer 8. The induction coil 9 is coaxially arranged with the refractory layer 8, and the power connector 2 of the induction heating component is disposed on the ladle body 1. During heating, the induction coil 9 is energized with alternating current to generate electromagnetic fields. These electromagnetic fields pass through the refractory layer 8 and reach the aluminum molten material inside, causing an eddy current effect in the aluminum molten material, which can heat the aluminum molten material.

[0033] This specific embodiment heats molten aluminum by embedding an induction heating component. It utilizes the principle of electromagnetic induction to heat the molten aluminum. Compared with heating with an electric heating tube, the molten aluminum generates heat directly inside, without the need for heat transfer from the outside through heat conduction. Moreover, the alternating magnetic field can penetrate deep into the molten aluminum, causing the entire molten aluminum to heat up rapidly. The heating speed is much faster than that of an electric heating tube, and the molten aluminum can be heated to a higher temperature in a short time. Furthermore, the eddy currents generated by the alternating magnetic field in the molten aluminum are relatively evenly distributed, making the internal temperature of the molten aluminum more uniform, which is beneficial to improving product quality.

[0034] like Figure 1 and Figure 2As shown, to avoid manual temperature measurement and heating at designated locations, this specific embodiment also includes a temperature detection component. The temperature detection component includes an electrically connected temperature sensor and a display 5. The temperature sensor is located inside the ladle body 1, and the display 5 is located on the outer surface of the ladle body 1. It also includes a portable power supply, which is electrically connected to the induction heating component. During forklift transport, the portable power supply can be placed on the forklift. The portable power supply has an inverter module that outputs AC power and is electrically connected to the induction heating component via a three-phase power line. In this specific embodiment, the temperature sensor is a K-type thermocouple. By adding the temperature detection component and the portable power supply, automatic heating can be achieved when the aluminum liquid temperature is lower than the set temperature, eliminating the need for manual temperature measurement and heating at fixed locations. This increases the heat preservation time of the transport ladle, making it more flexible and suitable for long-distance transport. In this specific embodiment, the portable power supply is an industrial-grade portable power supply, such as a diesel generator portable power supply or an aluminum-hydrogen chemical battery emergency power supply, capable of outputting power of over 20kW to meet heating needs. During use, the portable power supply can be used only for the transport ladle during the transport process, improving utilization and reducing investment costs.

[0035] Preferably, to ensure uniform heating of the molten aluminum, the induction heating component adopts medium-frequency induction heating.

[0036] like Figure 2 As shown, to reduce energy loss and shorten the heating time of molten aluminum, in this specific embodiment, the package 1 adopts a layered structure. The package 1 includes an energy storage layer 10 and a heat insulation layer 13, with a vacuum interlayer 11 between the heat insulation layer 13 and the energy storage layer 10. Specifically, the energy storage layer 10 is adjacent to and located outside the refractory layer 8. The energy storage layer 10 uses a high-temperature phase change material. The high-temperature phase change material can store the energy lost by the molten aluminum at high temperatures and release the absorbed energy at low temperatures, preventing the molten aluminum from losing too much heat to the outside. In this specific embodiment, the high-temperature phase change material uses a chloride-fluoride mixed salt. The insulation layer 13 is located outside the energy storage layer 10. The insulation layer 13 is made of refractory asbestos. An aluminum foil 12 is provided on the surface of the insulation layer 13 opposite to the energy storage layer 10. Through the action of the vacuum interlayer 11, the aluminum foil 12 and the insulation layer 13, the heat loss of the aluminum liquid can be reduced, the rate of temperature drop can be slowed down, and the heating time can be shortened or even eliminated, thereby improving the heat preservation performance of the ladle. Furthermore, the ladle body 1 also includes an insulating layer 14. The insulating layer 14 is located outside the insulation layer 13. The insulating layer 14 is made of ceramic fiber material. The insulating layer 14 plays a role in preventing scalding and improving the safety of use.

[0037] like Figure 2As shown, to further reduce heat loss, the cavities of the package 1 and the refractory layer 8 are ellipsoidal structures. By setting the cavities of both the package 1 and the refractory layer 8 to ellipsoidal structures, compared with cylindrical structures, the ellipsoidal structure has a smaller area under the same volume, which can reduce the contact area between the aluminum liquid and the inner wall of the transfer ladle, further reducing heat loss. The induction coil 9 is arranged around the ellipsoidal cavity, the center line of the induction coil 9 is coaxial with the cavity, and the diameter of the induction coil 9 decreases from top to bottom along the axial direction.

[0038] This specific embodiment also includes a cover 4, which is connected to the bag body 1 via a hinge assembly 3. The bag body 1 is also connected to an aluminum liquid channel 6, and a forklift groove 7 is provided at the bottom of the bag body 1.

[0039] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0040] 1. By using an embedded induction heating component, the aluminum liquid is heated by electromagnetic induction. The heat is generated directly inside the aluminum liquid without the need for heat conduction from the outside. The alternating magnetic field can penetrate deep into the aluminum liquid, causing the entire aluminum liquid to heat up quickly. The heating speed is much faster than that of an electric heating tube. It can heat the aluminum liquid to a higher temperature in a short time. In addition, the eddy currents generated by the alternating magnetic field in the aluminum liquid are relatively uniformly distributed, making the temperature inside the aluminum liquid more uniform.

[0041] 2. By adding temperature detection components and a mobile power supply, automatic heating can be achieved when the temperature of the molten aluminum is lower than the set temperature, eliminating the need for manual temperature measurement and heating at a fixed location. This increases the heat preservation time of the transfer ladle, making it more flexible and suitable for long-distance transportation.

[0042] 3. By using medium-frequency induction heating, the temperature change of the aluminum liquid can be more uniform, improving the uniformity of the temperature field of the aluminum liquid and improving the quality of the product.

[0043] 4. By using high-temperature phase change materials, the energy lost by molten aluminum can be stored at high temperatures and the absorbed energy can be released at low temperatures, thus preventing excessive heat loss from the molten aluminum to the outside world and avoiding large temperature changes in the molten aluminum, which helps to shorten the heating time.

[0044] 5. The heat loss of molten aluminum is reduced by setting the insulation layer 13; the insulation layer 14 is set to prevent scalding and improve the safety of use.

[0045] 6. The heat preservation effect on the molten aluminum is further enhanced by setting up a vacuum interlayer 11;

[0046] 7. By setting aluminum foil 12, heat radiation can be reflected, which greatly reduces the amount of heat radiation from the molten aluminum, thus playing a heat preservation role.

[0047] 8. By setting the cavity of the ladle body 1 and the refractory layer 8 as an ellipsoidal structure, compared with the cylindrical structure, the contact area between the aluminum liquid and the inner wall of the transfer ladle can be reduced under the same volume, thereby further reducing heat loss.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
