Description

Technical Field

[0001] This utility model relates to the field of aluminum molten metal transfer, and in particular to a cast aluminum transfer and heat preservation device. Background Technology

[0002] The teapot-type molten aluminum ladle is a commonly used aluminum molten metal transfer device in aluminum casting workshops. It is typically suspended and transported within the workshop. The teapot-type ladle generally has a barrel-shaped structure with tubular or spout-shaped outlets on the side. The pouring method resembles that of a teapot; the molten aluminum is poured out and injected into the mold by tilting the barrel. The top of the teapot-type ladle has a hook, allowing it to be hung on an overhead crane or a horizontal conveyor cable for movement during transport. It is mainly used for short- to medium-distance transfer of molten aluminum from the furnace to the processing workshop, and is suitable for various casting processes such as die casting and sand casting, meeting the aluminum molten metal transfer needs of different production scales and process requirements.

[0003] As described in patent CN222242629U, the teapot-type aluminum water tank has a simple structure, usually consisting of only a separate tank and an insulation layer. Its design operating temperature is 650-800℃, while the melting point of aluminum is 660℃. The operating temperature of the teapot-type aluminum water tank is close to the melting point of aluminum. Due to the way the teapot-type aluminum water tank is used, it cannot be equipped with a heating and insulation structure like a vehicle-mounted transport bag. This is because transporting the teapot-type aluminum water tank as a single unit would increase its weight if it were equipped with additional equipment. Furthermore, the high temperature of the aluminum water tank makes it too dangerous to install batteries on it.

[0004] It is evident that traditional teapot-style aluminum molten ladle can only achieve passive insulation through its own insulation layer. However, its design temperature is close to the melting point of aluminum, which is also the freezing point of molten aluminum. As a result, the portion of molten aluminum near the wall of the ladle is prone to solidification during transportation and pouring. Summary of the Invention

[0005] This invention addresses the problem of molten aluminum adhering to the wall of a teapot-shaped aluminum ladle easily solidifying by providing a cast aluminum transfer and insulation device with better heat preservation performance.

[0006] To address the aforementioned problems, this utility model employs a technical solution: a cast aluminum transfer and insulation device, comprising a hanging cable and an aluminum molten ladle. The aluminum molten ladle is suspended below the hanging cable. It also includes a positive electrode transmission line and a negative electrode transmission line, which are arranged parallel to the hanging cable. A heater is installed within the aluminum molten ladle, and the heater is connected to two power-collecting components. Each power-collecting component includes a power-collecting hook, which is respectively hooked onto the positive and negative electrode transmission lines. The power-collecting hooks are electrically connected to the heater. This solution utilizes external power supply, with the positive and negative electrode transmission lines supplying power to the heater via the power-collecting hooks. This keeps the power supply equipment away from the aluminum molten ladle, significantly reducing the risk. Furthermore, by adding only a heater to the aluminum molten ladle, it maintains a relatively light weight, thus achieving active insulation for the teapot-shaped aluminum molten ladle, greatly improving its insulation performance and preventing the aluminum molten ladle from solidifying.

[0007] As a preferred embodiment of the cast aluminum transfer and insulation device, the power-taking component further includes a mounting base. The bottom of the mounting base is fixedly connected to the aluminum molten ladle, and a spring is mounted on the top of the mounting base. An mounting plate is provided at the upper end of the spring, and a power-taking hook is disposed on the upper surface of the mounting plate. A first through hole is provided in the center of the mounting plate, and the connecting wire between the power-taking hook and the heater passes through the first through hole and the spring. The mounting plate is made of insulating material. The spring ensures the stability of the contact between the power-taking hook and the power transmission line, reducing the problem of power supply interruption to the heater due to poor contact and improving the reliability of the device operation. The orderly arrangement of the wires reduces the risk of wire wear and breakage, extending the service life of the wires. The insulating mounting plate enhances the safety performance of the device, preventing accidental electric shock to operators.

[0008] As a preferred embodiment of a cast aluminum transfer and insulation device, the mounting base includes a rotating base and two bases. The rotating base is hinged between the two bases, and the rotation axis between the rotating base and the bases is parallel to the rotation axis of the molten aluminum ladle during pouring. The bases are mounted on the molten aluminum ladle, and the spring is mounted on the rotating base. A second through hole is provided in the rotating base, through which the connecting wire between the power-taking hook and the heater passes. The hinged structure between the rotating base and the bases allows the power-taking component to adapt to the rotation of the molten aluminum ladle, reducing wear on the power-taking hook and the power transmission line caused by relative movement and extending their service life. Simultaneously, it avoids excessive stretching or twisting of the wires caused by the rotation of the molten aluminum ladle, further ensuring the stability of the circuit connection.

[0009] As a preferred embodiment of a cast aluminum transfer and insulation device, a lifting beam is provided at the top edge of the molten aluminum ladle, and a hook is located at the midpoint of the lifting beam along its length. The hook is hooked onto a hanging cable. Two power-collecting components are located at opposite ends of the lifting beam, and the positive and negative power transmission lines are located on opposite sides of the hanging cable. The midpoint suspension method of the lifting beam improves the balance of the molten aluminum ladle during transfer, reduces the risk of spillage, and enhances operational safety. The symmetrical arrangement of the power-collecting components ensures uniform force on the hooks, further guaranteeing stable power supply, and also makes the overall structure of the device more rational and compact.

[0010] As a preferred embodiment of a cast aluminum transfer and insulation device, in the height direction, the hinge shaft between the base and the rotating seat is flush with the hook, the positive and negative power transmission lines are higher than the hanging cable, and the spring is in a stretched state. The flush alignment of the hinge shaft with the hook reduces the impact of the power-taking component on the overall stability of the device when the aluminum ladle is flipped, making operation smoother; the stretched state of the spring ensures the pressure between the power-taking hook and the power transmission lines, further improving the reliability of electrical contact and avoiding heating interruptions due to poor contact.

[0011] As a preferred embodiment of a cast aluminum transfer and insulation device, the molten aluminum ladle includes an inner barrel and an outer barrel. The heater is a coil heater, located between the inner barrel and the outer barrel, and arranged around the inner barrel. The double-barrel structure enhances the insulation performance of the molten aluminum ladle and reduces heat loss. The surrounding arrangement of the coil heater ensures uniform heating of the molten aluminum, avoids solidification caused by localized low temperatures, improves the insulation effect, and ensures the fluidity of the molten aluminum.

[0012] As a preferred embodiment of a cast aluminum transfer and insulation device, the inner surface of the outer barrel is provided with an insulation layer, and the heater is located inside the insulation layer. The insulation layer further enhances the insulation capacity of the aluminum ladle, reduces energy consumption, improves the heating efficiency of the heater, and simultaneously reduces the temperature rise of the outer barrel, thus enhancing operational safety.

[0013] As a preferred embodiment of a cast aluminum transfer and insulation device, the inner tank is made of stainless steel. This allows it to withstand the high-temperature environment of molten aluminum, extending the service life of the inner tank. Its corrosion resistance reduces the erosion of the tank by the molten aluminum, ensuring the structural integrity of the molten aluminum ladle, while also preventing contamination of the molten aluminum by corrosion of the tank, thus guaranteeing the purity of the molten aluminum.

[0014] As can be seen from the above technical solutions, the advantages of this utility model are as follows: This solution adopts an external power supply method, keeping the power supply equipment away from the molten aluminum ladle, significantly reducing the risk. Simultaneously, the addition of a heater achieves active heat preservation, improving heat preservation performance, preventing molten aluminum from solidifying, and keeping the molten aluminum ladle relatively lightweight. The spring in the power supply assembly ensures stable contact between the power hook and the transmission line, reducing power interruptions and improving device reliability. The orderly arrangement of the wires reduces the risk of wear and breakage, extending service life. The insulating mounting plate enhances safety. The hinged structure between the rotating seat and the base adapts to the molten aluminum ladle's flipping motion, reducing wear on the power hook and transmission line, extending their lifespan, preventing excessive stretching and twisting of the wires, and ensuring stable circuit connections. The midpoint suspension of the lifting beam improves transport balance, reduces the risk of molten aluminum spillage, and enhances operation. For safety, the symmetrical arrangement of the power-taking components ensures uniform force on the power-taking hook, guaranteeing stable power supply and making the device structure more reasonable and compact. The hinge shaft is flush with the hook, reducing the impact of the power-taking components on the stability of the device and making operation smooth. The spring tension ensures the pressure between the power-taking hook and the power transmission line, improving the reliability of electrical contact and avoiding heating interruption. The double-layer tank enhances the heat preservation performance and reduces heat loss. The coil heater is arranged around the molten aluminum to ensure uniform heating, prevent solidification, and ensure fluidity. The heat preservation layer on the inner surface of the outer tank further enhances the heat preservation capacity, reduces energy consumption, improves heating efficiency, reduces the temperature rise of the outer tank, and enhances safety. The stainless steel inner tank is adapted to high-temperature environments, extends service life, and its corrosion resistance reduces aluminum erosion, ensuring the integrity of the aluminum ladle structure and the purity of the molten aluminum.

[0018] 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.

[0019] A casting aluminum transfer and insulation device includes a hanging cable 1 and an aluminum molten ladle 2. The aluminum molten ladle 2 is suspended below the hanging cable 1 and driven by a traction device in the workshop (this is a conventional auxiliary structure for a teapot-type aluminum molten ladle, which will not be described in detail here). Specifically, a hanging beam 10 is provided on the top edge of the aluminum molten ladle 2. The hanging beam 10 is arranged along one diameter of the aluminum molten ladle 2. A hook 11 is provided at the midpoint of the length direction of the hanging beam 10. During operation, the hook 11 is hooked onto the hanging cable 1, and the aluminum molten ladle 2 is transferred by the movement of the hanging cable 1. This method of suspending the aluminum molten ladle at the midpoint of the hanging beam can improve the balance of the aluminum molten ladle during transfer, reduce the risk of aluminum spillage, and enhance operational safety. The device also includes a positive electrode transmission line 3 and a negative electrode transmission line 4. The positive electrode transmission line 3 and the negative electrode transmission line 4 are arranged parallel to the hanging cable 1 and are located on both sides of the hanging cable 1, respectively.

[0020] The aluminum molten ladle 2 includes an inner barrel 21 and an outer barrel 22. The inner barrel 21 is used to hold the molten aluminum, while the outer barrel 22 protects the internal structure. The double-barrel structure enhances the insulation performance of the aluminum molten ladle and reduces heat loss. The inner barrel 21 is made of stainless steel, which can withstand the high-temperature environment of molten aluminum, extending its service life. Its corrosion resistance reduces the erosion of the barrel by the molten aluminum, ensuring the structural integrity of the aluminum molten ladle and preventing contamination of the molten aluminum by corrosion, thus ensuring the purity of the molten aluminum. The inner surface of the outer barrel 22 is provided with an insulation layer, which further enhances the insulation capacity of the aluminum molten ladle, reduces energy consumption, improves the heating efficiency of the heater, and reduces the temperature rise of the outer barrel 22, enhancing operational safety. A heater 5 is provided between the inner barrel 21 and the insulation layer (outer barrel 22). The heater 5 is a coil heater, which is located on the inner side of the insulation layer, between the inner barrel 21 and the outer barrel 22, and is arranged around the inner barrel 21. When working, the heat generated by the heater 5 is evenly transferred to the molten aluminum in the inner barrel 21. The surrounding arrangement of the coil heater makes the molten aluminum heated evenly, avoids the phenomenon of molten aluminum solidification caused by local low temperature, and ensures the fluidity of molten aluminum.

[0021] Power-collecting components are installed at both ends of the lifting beam 10. Each power-collecting component includes two hooks 6, which are respectively hooked onto the positive electrode transmission line 3 and the negative electrode transmission line 4. The hooks 6 are made of conductive material or have a conductive contact layer (such as graphite) on their surface. The hooks 6 are connected to the heater 5 via wires and supply power to it. During transport, the hooks 6 remain in contact with the transmission lines. The symmetrical arrangement of the power-collecting components ensures uniform force on the hooks, guaranteeing stable power supply and making the overall structure of the device more reasonable and compact. The hooks 6 are electrically connected to the heater 5 located in the aluminum ladle 2. During operation, current forms a circuit through the positive electrode transmission line 3, hooks 6, heater 5, the other hook 6, and the negative electrode transmission line 4, supplying power to the heater 5. This external power-collecting method keeps the power supply equipment away from the aluminum ladle, significantly reducing the risk. Simultaneously, by adding a heater only inside the aluminum ladle, active insulation is achieved, ensuring the aluminum ladle remains lightweight while improving insulation performance and preventing the molten aluminum from solidifying.

[0022] The power-collecting component also includes a mounting base 7, the bottom of which is fixedly connected to the aluminum ladle 2. The mounting base 7 includes a rotating seat 72 and two bases 71. The rotating seat 72 is hinged between the two bases 71. The rotation axis between the rotating seat 72 and the bases 71 is parallel to the rotation axis of the aluminum ladle 2 during pouring. The bases 71 are mounted on the aluminum ladle 2. When the aluminum ladle 2 is poured and rotated, the rotating seat 72 rotates synchronously around the hinge axis, allowing the power-collecting component to adapt to the rotation of the aluminum ladle. This hinge structure reduces wear on the power-collecting hook and transmission line caused by relative movement, extending their service life. It also prevents excessive stretching or twisting of the conductors due to the rotation of the aluminum ladle, ensuring stable circuit connection. Furthermore, in the height direction, the hinge axis between the bases 71 and the rotating seat 72 is flush with the hook 11, which reduces the impact of the power-collecting component on the overall stability of the device during aluminum ladle rotation, making operation smoother. The spring 8 is mounted on the rotating seat 72 and is in a stretched state. Its upper end is equipped with a mounting... During device operation, the elastic force of the spring ensures that the power-taking hook 6 remains tightly pressed against the surface of the power transmission line. Even if the aluminum ladle experiences slight shaking during transport, the spring's extension and contraction compensate for this, maintaining good electrical contact. The spring ensures the stability of the contact between the power-taking hook and the power transmission line, reducing power outages to the heater due to poor contact and improving the reliability of the device. The spring's tension ensures pressure between the power-taking hook and the power transmission line, further enhancing electrical contact reliability and preventing heating interruptions. The power-taking hook 6 is located on the upper surface of the mounting plate 9, which is made of insulating material to enhance device safety and prevent accidental electric shock to operators. It has a first through hole 12 at its center, and a second through hole 13 in the rotating seat 72. The connecting wire between the power-taking hook 6 and the heater 5 passes sequentially through the second through hole 13, the first through hole 12, and the spring 8. During device operation, this wire arrangement constrains and protects the wires, reducing the risk of wear and breakage and extending their service life. Furthermore, the positive power transmission line 3 and the negative power transmission line 4 are higher than the hanging cable 1.

[0023] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: This solution adopts an external power supply method, keeping the power supply equipment away from the molten aluminum ladle, significantly reducing the risk; at the same time, the addition of a heater achieves active heat preservation, improving heat preservation performance, preventing the molten aluminum from solidifying, and keeping the molten aluminum ladle relatively lightweight; the spring in the power supply component ensures stable contact between the power supply hook and the transmission line, reducing power interruptions and improving the reliability of the device; the orderly arrangement of the wires reduces the risk of wear and breakage, extending service life; the insulating mounting plate enhances safety; the hinged structure between the rotating seat and the base adapts to the flipping action of the molten aluminum ladle, reducing wear on the power supply hook and transmission line, extending service life, preventing excessive stretching and twisting of the wires, and ensuring stable circuit connection; the midpoint suspension of the lifting beam improves the balance of transportation, reduces the risk of molten aluminum spillage, and enhances the ease of operation. For safety, the symmetrical arrangement of the power-taking components ensures uniform force on the power-taking hook, guaranteeing stable power supply and making the device structure more reasonable and compact. The hinge shaft is flush with the hook, reducing the impact of the power-taking components on the stability of the device and making operation smooth. The spring tension ensures the pressure between the power-taking hook and the power transmission line, improving the reliability of electrical contact and avoiding heating interruption. The double-layer tank enhances the heat preservation performance and reduces heat loss. The coil heater is arranged around the molten aluminum to ensure uniform heating, prevent solidification, and ensure fluidity. The heat preservation layer on the inner surface of the outer tank further enhances the heat preservation capacity, reduces energy consumption, improves heating efficiency, reduces the temperature rise of the outer tank, and enhances safety. The stainless steel inner tank is adapted to high-temperature environments, extends service life, and its corrosion resistance reduces aluminum erosion, ensuring the integrity of the aluminum ladle structure and the purity of the molten aluminum.
