Description

Technical Field

[0001] This utility model belongs to the field of metal smelting technology, specifically a metal smelting liquid lifting device. Background Technology

[0002] In modern industrial production, metal smelting is a crucial step, especially the smelting of aluminum and aluminum alloys, which has wide applications in many fields such as aerospace, automobile manufacturing, and electronics. After aluminum is smelted in an aluminum melting furnace, in order to ensure the temperature and fluidity of the molten aluminum for subsequent casting, processing and other processes, the molten aluminum needs to be lifted from the aluminum melting furnace and transported to a holding furnace for heat preservation. Traditionally, the lifting and lowering of molten aluminum is generally done manually, which results in high labor intensity, low efficiency and safety hazards.

[0003] Chinese patent CN216274318U discloses an aluminum liquid lifting device that draws molten aluminum into a riser pipe and discharges it through a chute outlet, eliminating the need for height differences. This device is simple, compact, low-cost, has few vulnerable parts, and is easy to operate. However, this lifting device requires adjusting the cantilever to determine the working height of the riser pipe each time it is used, making operation complex and inefficient. Furthermore, the chute outlet of this device is an open design, resulting in significant heat loss during the transport of the molten aluminum, which is detrimental to maintaining its good fluidity and processing performance.

[0004] Therefore, there is an urgent need for a metal smelting liquid lifting device, which improves the automation level of aluminum liquid transportation, ensures the continuity and stability of the aluminum smelting production process, and can reduce heat loss during aluminum liquid transportation, maintaining its good fluidity and process performance. Utility Model Content

[0005] The purpose of this invention is to provide a metal smelting liquid lifting device to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A metal smelting molten material lifting device, comprising: Aluminum melting furnaces and holding furnaces; The aluminum melting furnace is provided with a support base at the top, and a first conveying pipe is provided between the inner wall of the top of the support base and the bottom of the aluminum melting furnace, and is connected to the aluminum melting furnace; The support base is provided with a driving mechanism at the top, a push plate is provided on one side of the driving mechanism, a push rod is provided at the bottom of the push plate, the push rod extends into the first delivery pipe, and a liquid extraction mechanism is provided at the bottom of the push rod; The section of the first conveying pipe located on the support base is equipped with a guide pipe, and the aluminum melting furnace is connected to the holding furnace through the guide pipe; The guide pipe is located at one end of the aluminum melting furnace, which is higher than the end of the guide pipe located in the holding furnace.

[0007] The metal smelting liquid lifting device according to the present invention has at least the following technical effects: This molten aluminum lifting device, through a drive mechanism that sequentially drives a push plate, a push rod, and a pumping mechanism, enables the molten aluminum in the aluminum melting furnace to flow upwards. The molten aluminum is then transported to the holding furnace via an inclined guide pipe using its own gravity, eliminating the need for additional power equipment to propel the flow within the guide pipe. Compared to traditional aluminum melting furnace lifting devices, this application eliminates the need to adjust the working height of the cantilever and the riser pipe; simply activating the drive mechanism is sufficient to lift the molten aluminum via the pumping mechanism. This significantly improves the automation level of molten aluminum transport, ensuring the continuity and stability of the aluminum melting production process. Furthermore, it reduces heat loss during transport, maintaining good fluidity and process performance, thus meeting the production and usage requirements of metal smelting.

[0008] As a further embodiment of this utility model: the top of the heat preservation furnace is connected to a second conveying pipe, and one end of the guide pipe is connected to the second conveying pipe.

[0009] Because the top of the holding furnace is connected to a second conveying pipe, and one end of the guide pipe is connected to the second conveying pipe; that is, the molten aluminum lifted from the aluminum melting furnace is transported to the holding furnace through the guide pipe and then through the second conveying pipe, the conveying path of the molten aluminum can be adjusted more flexibly, making the arrangement of the positions of the aluminum melting furnace and the holding furnace more reasonable, avoiding the impact of space constraints on equipment installation and the smoothness of the production process, and minimizing heat loss of the molten aluminum during the conveying process, ensuring that the molten aluminum enters the holding furnace at a higher temperature, maintaining its good fluidity and process performance.

[0010] As a further embodiment of this utility model, the first conveying pipe, the guide pipe, and the second conveying pipe are each made of ceramic material independently.

[0011] During the aluminum melting process, the temperature of the molten aluminum is usually very high. By independently selecting ceramic materials for the first conveying pipe, the guide pipe, and the second conveying pipe, the ceramic material can effectively resist high temperature and corrosion, enabling the first conveying pipe, the guide pipe, and the second conveying pipe to withstand the long-term scouring and erosion of the high-temperature molten aluminum without deformation or damage. This ensures that the conveying pipes work stably in a high-temperature environment and guarantees the continuity and safety of the molten aluminum conveying process.

[0012] As a further embodiment of this utility model, a pad is provided between the top of the first conveying pipe and the inner wall of the top of the support base.

[0013] As a further improvement of this utility model, the pad is made of carbon fiber.

[0014] By setting a pad between the top of the first conveying pipe and the inner wall of the top of the support base, and the pad is made of carbon fiber; carbon fiber material has extremely high strength, which can provide reliable support for the first conveying pipe, prevent the first conveying pipe from being damaged due to excessive local stress, and ensure the structural stability of the first conveying pipe during operation.

[0015] As a further embodiment of this invention: the liquid extraction mechanism includes a connecting rod, the top of which is connected to the bottom of the push rod.

[0016] As a further embodiment of this utility model: a partition is provided at the bottom of the connecting rod, and the outer diameter of the partition is adapted to the inner diameter of the first conveying pipe.

[0017] The pumping mechanism includes a connecting rod, the top of which is connected to the bottom of a push rod. A partition is located at the bottom of the connecting rod, its outer diameter matching the inner diameter of the first conveying pipe. When the molten aluminum needs to be kept warm, the drive mechanism is activated. This mechanism lifts the push plate and push rod upwards, causing the connecting rod to move the partition upwards simultaneously. At this time, the molten aluminum flows into the first conveying pipe from the bottom. As the partition rises, the volume of molten aluminum in the first conveying pipe increases. When the molten aluminum reaches the guide pipe, it flows into the guide pipe. Due to the inclined design of the guide pipe, the molten aluminum flows to the other end of the guide pipe by its own gravity and then enters the holding furnace after passing through the second conveying pipe. This achieves the conveying of molten aluminum from the aluminum melting furnace to the holding furnace for heat preservation. This device effectively improves the convenience and efficiency of molten aluminum conveying, reduces the labor intensity and safety hazards of manually lifting molten aluminum, and eliminates the need for additional power equipment during the stage of conveying molten aluminum from the guide pipe to the holding furnace, saving energy consumption and reducing the complexity and cost of the equipment.

[0018] As a further improvement of this utility model, a gasket is provided between the connecting rod and the partition block.

[0019] By placing a gasket between the connecting rod and the spacer, the connection strength between the connecting rod and the spacer can be effectively improved, and the molten aluminum can be prevented from seeping into the connecting rod during the lifting process. The gasket can fill the tiny gap between the connecting rod and the spacer, forming a good sealing effect. At the same time, it helps to maintain the pressure stability in the first conveying pipe, ensuring that the molten aluminum can be smoothly drawn into the first conveying pipe, thereby improving the pumping and conveying efficiency.

[0020] As a further improvement of this utility model, the connecting rod, the spacer, and the gasket are each made of carbon fiber.

[0021] Because the connecting rod, partition, and gasket are each made of carbon fiber, the push rod can withstand greater tensile and compressive forces without deformation or breakage when it drives the connecting rod, partition, and gasket to move. Furthermore, carbon fiber has a relatively low thermal conductivity, which reduces the transfer of heat to other components and prevents damage to other parts of the equipment due to high temperatures. At the same time, carbon fiber has good thermal stability, especially in inert gas environments, where it can withstand temperatures above 2000℃. This ensures that there will be no significant deformation or performance degradation at high temperatures, guaranteeing stable operation of the pumping mechanism under high-temperature conditions.

[0022] As a further embodiment of this utility model: a mounting base is provided on one side of the aluminum melting furnace, and an inclined surface is provided on the top of the mounting base. The inclination angle of the inclined surface is adapted to the inclination angle of the guide pipe. A limiting pipe is provided on the top of the inclined surface, and the guide pipe passes through the limiting pipe.

[0023] An installation base is set on one side of the aluminum melting furnace, and an inclined surface is set on the top of the installation base. The inclination angle of the inclined surface is adapted to the inclination angle of the guide tube. A limiting tube is set on the top of the inclined surface, and the guide tube passes through the limiting tube. The limiting tube can provide stable support for the guide tube, preventing the drive mechanism and the impact force when the aluminum liquid flows through the guide tube from causing the guide tube to vibrate or shake, thus ensuring the stability and reliability of the guide tube when transporting aluminum liquid.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] like Figure 1-3The present invention, as shown in this embodiment, provides a metal smelting liquid lifting device, comprising: an aluminum melting furnace 1 and a holding furnace 2; a support base 3 is provided on the top of the aluminum melting furnace 1, and a first conveying pipe 4 is provided between the inner wall of the top of the support base 3 and the bottom of the aluminum melting furnace 1, and is connected to the aluminum melting furnace 1; a driving mechanism 5 is provided on the top of the support base 3, a push plate 6 is provided on one side of the driving mechanism 5, a push rod 7 is provided at the bottom of the push plate 6, the push rod 7 extends into the first conveying pipe 4, and a liquid extraction mechanism 8 is provided at the bottom of the push rod 7; a guide pipe 9 is provided on the section of the first conveying pipe 4 located in the support base 3, and the aluminum melting furnace 1 is connected to the holding furnace 2 through the guide pipe 9; the end of the guide pipe 9 located in the aluminum melting furnace 1 is higher than the end of the guide pipe 9 located in the holding furnace 2.

[0034] Specifically, the molten aluminum lifting device, driven by the drive mechanism 5, sequentially drives the push plate 6, the push rod 7, and the pumping mechanism 8, enabling the molten aluminum in the aluminum melting furnace 1 to flow upwards. The molten aluminum is then transported to the holding furnace 2 via an inclined guide pipe 9 using its own gravity, eliminating the need for additional power equipment to propel the molten aluminum within the guide pipe 9. Compared to traditional aluminum melting furnace lifting devices, this application eliminates the need to adjust the working height of the cantilever and the riser pipe; simply activating the drive mechanism 5 is sufficient to lift the molten aluminum via the pumping mechanism 8. This significantly improves the automation level of molten aluminum transport, ensuring the continuity and stability of the aluminum melting production process. Furthermore, it reduces heat loss during molten aluminum transport, maintaining its good fluidity and process performance, thus meeting the production and usage requirements of metal smelting.

[0035] Furthermore, the top of the heat preservation furnace 2 is connected to a second conveying pipe 10, and one end of the guide pipe 9 is connected to the second conveying pipe 10.

[0036] Specifically, since the top of the holding furnace 1 is connected to the second conveying pipe 10, and one end of the guide pipe 9 is connected to the second conveying pipe 10; that is, the aluminum liquid lifted up from the aluminum melting furnace 1 is conveyed to the holding furnace 2 through the guide pipe 9 and then through the second conveying pipe 10. This allows for more flexible adjustment of the conveying path of the aluminum liquid, making the arrangement of the positions of the aluminum melting furnace 1 and the holding furnace 2 more reasonable, avoiding the impact of space constraints on equipment installation and the smoothness of the production process, and minimizing heat loss of the aluminum liquid during the conveying process, ensuring that the aluminum liquid enters the holding furnace at a higher temperature, maintaining its good fluidity and process performance.

[0037] Furthermore, the first conveying pipe 4, the guide pipe 9, and the second conveying pipe 10 are each made of ceramic material independently.

[0038] Specifically, during the aluminum melting process, the temperature of the molten aluminum is usually very high. By independently selecting ceramic materials for the first conveying pipe 4, the guide pipe 9, and the second conveying pipe 10, the ceramic material can effectively resist high temperatures and corrosion, enabling the first conveying pipe 4, the guide pipe 9, and the second conveying pipe 10 to withstand the long-term scouring and erosion of the high-temperature molten aluminum without deformation or damage. This ensures that each conveying pipe works stably in a high-temperature environment and guarantees the continuity and safety of the molten aluminum conveying process.

[0039] According to embodiments of the present invention, such as Figure 2 and 3 As shown, a pad 11 is provided between the top of the first conveying pipe 4 and the inner wall of the top of the support 3, and the pad 11 is made of carbon fiber.

[0040] Specifically, a pad 11 is provided between the top of the first conveying pipe 4 and the inner wall of the top of the support base 3, and the pad 11 is made of carbon fiber. The carbon fiber material has extremely high strength and can provide reliable support for the first conveying pipe 4, preventing the first conveying pipe 4 from being damaged due to excessive local stress, and ensuring the structural stability of the first conveying pipe 4 during operation.

[0041] According to embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the liquid extraction mechanism 8 includes a connecting rod 801, the top of which is connected to the bottom of the push rod 7; a partition 802 is provided at the bottom of the connecting rod 801, and the outer diameter of the partition 802 is adapted to the inner diameter of the first delivery pipe 4.

[0042] Specifically, the pumping mechanism 8 includes a connecting rod 801, the top of which is connected to the bottom of the push rod 7. A partition 802 is provided at the bottom of the connecting rod 801, and the outer diameter of the partition 802 matches the inner diameter of the first conveying pipe 4. When it is necessary to keep the molten aluminum liquid warm, the drive mechanism 5 is activated. The drive mechanism 5 drives the push plate 6 and the push rod 7 upwards, causing the connecting rod 801 to move upwards along with the partition 802. At this time, the aluminum liquid flows in from the bottom of the first conveying pipe 4, and as the partition 802 rises, the volume of aluminum liquid in the first conveying pipe 4 also increases. When the molten aluminum rises to the guide pipe 9, it flows into the guide pipe 9. Due to the inclined setting of the guide pipe 9, the molten aluminum flows to the other end of the guide pipe 9 by its own gravity, and enters the holding furnace 2 after passing through the second conveying pipe 10. This realizes the transportation of molten aluminum from the aluminum melting furnace 1 to the holding furnace 2, and performs heat preservation treatment on the molten aluminum. This device effectively improves the convenience and efficiency of molten aluminum transportation, reduces the labor intensity and safety hazards of manually lifting molten aluminum, and the stage of transporting molten aluminum from the guide pipe 9 to the holding furnace 2 does not require additional power equipment, which saves energy consumption and reduces the complexity and cost of the equipment.

[0043] Furthermore, a gasket 803 is provided between the connecting rod 801 and the spacer 802.

The gasket 803 can fill the tiny gap between the connecting rod 801 and the spacer 802 to form a good sealing effect. At the same time, it helps to maintain the pressure stability in the first conveying pipe 4, ensuring that the aluminum liquid can be smoothly drawn into the first conveying pipe 4, thereby improving the pumping and conveying efficiency.

[0045] Furthermore, the connecting rod 801, the spacer 802, and the gasket 803 are each made of carbon fiber.

[0046] Specifically, since the connecting rod 801, the spacer 802, and the gasket 803 are each made of carbon fiber, the push rod 7 can withstand greater tensile and compressive forces without deformation or breakage when it drives the connecting rod 801, the spacer 802, and the gasket 803 to move. Furthermore, carbon fiber has a relatively low thermal conductivity, which reduces the transfer of heat to other components and avoids damage to other parts of the equipment due to high temperatures. At the same time, carbon fiber has good thermal stability, especially in inert gas environments, where it can withstand temperatures above 2000℃. This ensures that there will be no significant deformation or performance degradation in high-temperature environments, guaranteeing stable operation of the liquid pumping mechanism under high-temperature conditions.

[0047] It should also be noted that, as Figure 3 As shown, a mounting base 12 is provided on one side of the aluminum melting furnace 1. The top of the mounting base 12 is provided with an inclined surface. The inclination angle of the inclined surface is adapted to the inclination angle of the guide pipe 9. A limit pipe 13 is provided at the top of the inclined surface, and the guide pipe 9 passes through the limit pipe 13.
