DETAILED DESCRIPTION

[0018] The present application is further described in conjunction with the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present application and not to limit the scope of the present application. In addition, it should be understood that after reading the content taught by the present application, those skilled in the art can make various modifications or modifications to the present application, and these equivalent forms also fall within the scope defined by the present application.

[0019] Example: A novel tilting resistance melting furnace like Figures 1-5 As shown, a novel tilting resistance melting furnace has the following specific structure: A support frame 10 and a smelting furnace body 20 hinged to its top are provided. Two symmetrically arranged support seats 101 are fixedly installed on one side of the top surface of the support frame 10. One side of the top of the smelting furnace body 20 is hinged to the upper end of the opposite support seats 101. A heat-insulating furnace cover 30 is hinged to the top of the smelting furnace body 20. A first sealing packing is provided between the heat-insulating furnace cover 30 and the smelting furnace body 20. A blow-off port 301 is opened at the center of the top surface of the heat-insulating furnace cover 30. A sealing cover 302 that mates with the blow-off port 301 is hinged to the top surface of the heat-insulating furnace cover 30. A second sealing packing is provided between the blow-off port 301 and the sealing cover 302. The smelting furnace... A crucible 40 is fixedly installed inside the main body 20. The upper edge of the crucible 40 is fixedly connected to the top opening of the main body 20. A heating chamber 201 is formed between the outer periphery of the crucible 40 and the inner wall of the main body 20. Several evenly distributed electric heating wires 50 are provided in the heating chamber 201. The electric heating wires 50 are fixedly installed on the inner wall of the main body 20. A discharge assembly 60 is provided on the upper end of the main body 20 near the support base 101. An emergency aluminum discharge port 204 communicating with the interior is fixedly installed at the bottom of the outer side of the main body 20. The emergency aluminum discharge port 204 is located below the discharge assembly 60. A valve is provided at the emergency aluminum discharge port 204.

[0020] The working principle described above is as follows: In use, the support frame 10 provides fixed support for the entire device. Two symmetrical support seats 101 on one side of its top surface are hinged to one side of the top of the smelting furnace body 20, forming a rotating basis for tilting the furnace body and ensuring that the smelting furnace body 20 can rotate stably around the hinge point. The heat-insulating furnace cover 30 is hinged to the top of the smelting furnace body 20. The first sealing packing between the two forms a seal when the heat-insulating furnace cover 30 is closed, reducing heat loss and the entry of external gases. The blowhole 301 on the top surface of the heat-insulating furnace cover 30 is used for subsequent degassing operations. The second sealing packing between the sealing cover 302 and the blowhole 301 can close the blowhole 301 during non-degassing stages, maintaining a sealed environment inside the furnace. The crucible 40 is fixed to the smelting furnace body. Inside the furnace body 20, the electric heating wire 50 in the heating chamber 201 formed by its outer periphery and the inner wall of the furnace body generates heat when energized, and the heat is transferred to the crucible 40 to achieve the melting of non-ferrous metals (such as aluminum alloys and magnesium alloys). The upper edge of the crucible 40 is fixedly connected to the top opening of the furnace body 20 to ensure the stability of the crucible 40 during melting and tilting. The discharge assembly 60 is set on the upper end of the furnace body 20 near the support base 101, and works with the crucible 40 to discharge the molten metal after melting. The emergency aluminum discharge port 204 at the bottom of the outer side of the furnace body 20 is connected to the furnace, which can quickly discharge leaking aluminum in case of sudden events such as crucible breakage, reduce the risk of equipment damage and safety hazards, and ensure production safety. An insulation layer 202 is fixedly installed on the inner wall of the smelting furnace body 20. A high-temperature resistant layer 203 is provided on the surface of the insulation layer 202, and a plurality of evenly distributed electric heating wires 50 are densely arranged on the surface of the high-temperature resistant layer 203. The insulation layer 202, fixedly installed on the inner wall of the smelting furnace body 20, can prevent the heat generated by the electric heating wires 50 in the heating chamber 201 from being transferred to the outside of the furnace, reducing heat loss. The high-temperature resistant layer 203 on the surface of the insulation layer 202 is in direct contact with the heating chamber 201 and can withstand the high temperature of the electric heating wires 50 during operation, preventing damage to the insulation layer 202 due to high temperature. At the same time, it fixes the electric heating wires 50 to the surface of the high-temperature resistant layer 203, ensuring stable heating wire position, more uniform heat transfer, and preventing the heating wires from loosening or being damaged due to damage to the insulation layer, thus extending the overall service life of the equipment.

[0021] The insulation layer 202 is made of aluminum silicate fiberboard, and the high-temperature resistant layer 203 is made of mullite. The aluminum silicate fiberboard used in the insulation layer 202 has excellent thermal insulation performance, which can significantly reduce the rate of heat conduction from the furnace to the outside and maintain the temperature stability inside the heating chamber 201. The mullite used in the high-temperature resistant layer 203 has high strength and high temperature resistance (can withstand temperatures above 1600℃), and can directly withstand the high-temperature environment when the electric heating wire 50 is working. At the same time, its structural stability can ensure the stable fixation of the electric heating wire 50 and prevent the heating wire from shifting during the heating process.

[0022] The crucible 40 includes a U-shaped part 401 and a V-shaped part 402. The V-shaped part 402 is integrally fixedly installed on the side of the U-shaped part 401, and the V-shaped part 402 extends outward along the bottom tangent direction of the U-shaped part 401. The side of the V-shaped part 402 is provided with a liquid outlet 403, and the shape of the melting furnace body 20 is adapted to the shape of the crucible 40. The discharge assembly 60 is connected to the liquid outlet 403. The U-shaped section 401 of the crucible 40 provides a space for non-ferrous metal smelting, used to hold metal raw materials and molten metal. The V-shaped section 402 is integrally fixed with the U-shaped section 401 and extends outward along the tangential direction of the bottom of the U-shaped section 401, avoiding the fluctuation of molten metal transport caused by the upward displacement of the outlet of the traditional crucible, reducing the absorption of air and slag formation of molten metal during the transport process, and improving the purity of molten metal. The outlet 403 on the side of the V-shaped section 402 is connected to the discharge assembly 60. The shape of the smelting furnace body 20 is adapted to the crucible 40, ensuring that the heat generated by the electric heating wire 50 in the heating chamber 201 can be evenly transferred to all parts of the crucible 40. At the same time, when the furnace body is tilted, the molten metal in the crucible 40 can flow smoothly along the tangential direction of the V-shaped section 402 to the outlet 403, and then be discharged through the discharge assembly 60.

[0023] The discharge assembly 60 includes: Connector 601: The upper part of the smelting furnace body 20 near the support base 101 is integrally and fixedly installed with the connector 601, which communicates with the interior of the furnace body 20. The inner side of the connector 601 is fixedly connected to the liquid outlet 403. Fixed connector 602, one end of fixed connector 602 is fixedly connected to the outer side of connector 601; Rotary joint 603 is fixedly installed at the other end of the fixed joint 602.

[0024] In the discharge assembly 60, the connector 601 is integrally fixed to the furnace body 20 and communicates with the furnace interior. Its inner side is fixedly connected to the liquid outlet 403 of the crucible 40, ensuring that the molten metal can flow smoothly from the liquid outlet 403 into the connector 601. The fixed joint 602, together with the connector 601 and the rotary joint 603, forms a channel for conveying molten metal. The rotary joint 603 can rotate slightly with the furnace body when the furnace body is tilted, and at the same time connects to the production line chute to ensure that the channel for molten metal is always unobstructed during the conveying process, avoiding the twisting or breakage of the discharge channel due to the tilting of the furnace body.

[0025] Lubricating sealing gaskets, made of stainless steel mesh and pressed flake graphite, are provided between the fixed joint 602 and the rotary joint 603, and between the fixed joint 602 and the connector 601. The stainless steel mesh skeleton of the lubricating sealing gasket ensures structural strength, while the flake graphite body provides excellent sealing and lubrication. The stainless steel mesh skeleton enhances the gasket's resistance to pressure and deformation, and the elastic deformation properties of the flake graphite can accommodate slight misalignment between the joints, ensuring a good sealing effect even during long-term use of the equipment or when temperature changes cause minor deformation of the components. During the metal molten material transport process, the sealing gasket fills the gaps between the joints, preventing metal molten material leakage and the entry of external air. At the same time, it provides lubrication when the rotary joint 603 rotates, reducing friction and wear between the joints.

[0026] A support plate 70 is integrally fixedly installed at the upper edge of the smelting furnace body 20. The upper ends of the support bases 101 are rotatably connected to the support plate 70 through corresponding hinge seats. Support beams 701 are fixedly installed on the front and rear sides of the bottom surface of the support plate 70. First hydraulic cylinders 702 are fixedly hinged on the front and rear sides of the top surface of the support frame 10. The ends of the movable rods of the first hydraulic cylinders 702 are hinged to the bottom of the support beams 701 on the same side. The first hydraulic cylinders 702 are located on the side close to the discharge assembly 60. The support plate 70 at the upper edge of the smelting furnace body 20 is rotatably connected to the support base 101 through a hinge, forming a pivot point for tilting the furnace body. The support beams 701 on the front and rear sides of the bottom of the support plate 70 provide connection points for the first hydraulic cylinder 702. When the movable rod of the first hydraulic cylinder 702, which is hinged to the top surface of the support frame 10, extends or retracts, it can push the support beam 701, causing the support plate 70 and the smelting furnace body 20 to tilt around the hinge point of the support base 101, thereby realizing the pouring of molten metal or the resetting of the furnace body.

[0027] The rear side of the heat-insulating furnace cover 30 is hinged to the rear part of the top surface of the support plate 70. A second hydraulic cylinder 80 is hinged to the center of the rear side of the top surface of the support frame 10. An extension plate 801 is hinged to the end of the movable rod of the second hydraulic cylinder 80. One end of the extension plate 801 is fixedly connected to the top surface of the heat-insulating furnace cover 30. The rear side of the heat-insulating furnace cover 30 is hinged to the rear part of the top surface of the support plate 70, forming a rotating base for opening or closing the furnace cover. When the movable rod of the second hydraulic cylinder 80 on the rear side of the top surface of the support frame 10 extends or retracts, it can drive the extension plate 801 to rotate, thereby pulling or pushing the heat-insulating furnace cover 30 to rotate around the hinge point, realizing the opening or closing of the heat-insulating furnace cover 30. The operation is simple and convenient. Both the first hydraulic cylinder 702 and the second hydraulic cylinder 80 are equipped with a complete hydraulic control system.

[0028] An air inlet pipe 90 is fixedly installed on the top surface of the heat-insulating furnace cover 30, and a connecting flange is fixedly provided at the upper end of the air inlet pipe 90. The air inlet pipe 90 on the top surface of the heat-insulating furnace cover 30 communicates with the interior of the smelting furnace body 20, and the connecting flange at its upper end can be connected to the gas circuit control cabinet. During the smelting process, the gas circuit control cabinet introduces protective gases such as argon into the furnace through the air inlet pipe 90 to fill the furnace space, exhaust air, and form an inert atmosphere environment to prevent the molten metal from oxidizing upon contact with air.

[0029] The junction box 501 on the side of the smelting furnace body 20 away from the discharge assembly 60 has several evenly distributed terminals for electric heating wires 50 and circuit protection devices inside. The external power supply line is electrically connected to the electric heating wires 50 through the junction box 501 to realize the power control of the electric heating wires 50. At the same time, the junction box 501 can protect the terminals from external dust and moisture corrosion and prevent short circuits or poor contact.
