Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid transfer technology, and in particular to an aluminum liquid lifting device. Background Technology

[0002] To transfer molten aluminum from a smelting furnace to an induction furnace, a height difference technique is typically used. Currently, two main methods are employed: one involves designing the smelting furnace at a higher position, allowing the molten aluminum to be transferred naturally from top to bottom; the other uses a lifting platform and transfer containers to transport the molten aluminum to a higher location for transfer. Both methods require significant investment in equipment and occupy a large area. Therefore, there is an urgent need for an aluminum molten metal lifting device that can transfer molten aluminum from a smelting furnace to an induction furnace without relying on the height difference between the smelting furnace and the transfer furnace. This would not only reduce equipment investment but also effectively reduce the equipment's footprint. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-4 This utility model discloses an aluminum liquid lifting device, including a support plate 1. A lifting component for controlling the height of the support plate 1 is fixedly connected to one side of the bottom surface of the support plate 1. A cylinder 4 for extending into the melting furnace is fixedly connected to the other side of the bottom surface of the support plate 1. A guide pipe 5 for guiding the aluminum liquid into the induction furnace is fixedly connected and communicated with the cylinder 4. A guide component for guiding the aluminum liquid in the melting furnace into the guide pipe 5 is provided inside the cylinder 4.

[0025] This invention uses a flow-guiding component installed inside the cylinder 4 to guide the molten aluminum in the smelting furnace to the flow-guiding pipe 5, and then guides the molten aluminum to the induction furnace through the flow-guiding pipe 5. This allows the molten aluminum in the smelting furnace to be transferred to the induction furnace without relying on the height difference between the smelting furnace and the transfer furnace. This not only reduces the investment in the equipment, but also effectively reduces the footprint of the equipment.

[0026] The design is further optimized so that the lifting assembly includes a hydraulic cylinder 2. The fixed end of the hydraulic cylinder 2 is fixedly installed on the ground on the side of the smelting furnace away from the induction furnace via a bracket, and the piston end of the hydraulic cylinder 2 is fixedly connected to the support plate 1. The bracket allows the hydraulic cylinder 2 to be stably installed on the ground on the side of the smelting furnace away from the induction furnace, enabling the hydraulic cylinder 2 to stably drive the support plate 1 to rise and fall.

[0027] The hydraulic cylinder 2 is mainly composed of external and internal structures.

[0028] The external structure includes:

[0029] Cylinder (cylinder block): The main structure, usually made of high-strength steel tubing, with precision internal machining, used to house the piston and hydraulic oil.

[0030] Front end cap (guide sleeve): Installed at the front end of the cylinder, it supports the piston rod and prevents contaminants from entering. It has a built-in guide ring and seal.

[0031] Rear end cover (bottom cover): Seals the rear end of the cylinder and is fixed to the cylinder by bolts or welding, bearing oil pressure.

[0032] Mounting supports: used to fix hydraulic cylinders, common types include cleat type, flange type or hinge type.

[0033] The internal structure includes:

[0034] Piston: Divides the cylinder into two chambers (rod chamber and rodless chamber) and prevents oil leakage through seals.

[0035] Piston rod: One end is connected to the piston, and the other end extends out of the front end cap and is connected to the load. The surface is plated with hard chrome to improve wear resistance.

[0036] Sealing system: Piston seal (such as Glyd ring, Step seal): Prevents oil leakage between the two chambers.

[0037] Rod seals (such as Y-rings, dust seals): prevent oil leakage and contaminant intrusion.

[0038] Guide ring: Reduces friction and wear between the piston rod and the front cover.

[0039] The working principle of hydraulic cylinder 2: Hydraulic cylinder 2 is based on Pascal's principle, and drives the piston to move through oil pressure; when pressurized oil enters the rodless chamber, it pushes the piston to move outward, and the oil in the rod chamber flows back to the oil tank, completing the extension stroke; when pressurized oil enters the rod chamber, the piston rod retracts, and the oil in the rodless chamber is discharged, completing the retraction stroke; hydraulic cylinder 2 has high control precision and is suitable for engineering machinery, industrial equipment, etc.

[0040] Features of hydraulic cylinder 2:

[0041] High load capacity: By increasing the oil pressure (e.g., above 21MPa), huge thrust can be output.

[0042] Adjustable speed: The flow rate of the oil is controlled by a flow valve to achieve stepless speed regulation.

[0043] Compact structure: smaller in size than electric actuators with the same power.

[0044] High reliability: Mature sealing technology and long service life.

[0045] Further optimization of the scheme: after the piston end of the hydraulic cylinder 2 extends, the bottom of the cylinder 4 is positioned above the smelting furnace and the guide pipe 5 is positioned above the induction furnace.

[0046] After the piston end of the hydraulic cylinder 2 extends, the bottom of the cylinder 4 can be positioned above the smelting furnace, allowing the furnace lid to be closed. At the same time, the guide pipe 5 can also be positioned above the induction furnace, allowing the induction furnace lid to be closed as well.

[0047] Further optimization of the scheme allows the bottom of the cylinder 4 to be close to the bottom of the melting furnace after the piston end of the hydraulic cylinder 2 retracts, and the end of the guide pipe 5 away from the cylinder 4 to be close to the induction furnace.

[0048] After the piston end of the hydraulic cylinder 2 retracts, the bottom of the cylinder 4 can be extended into the melting furnace and close to the bottom of the melting furnace, so that the molten aluminum can enter the cylinder 4; at the same time, the end of the guide pipe 5 away from the cylinder 4 can be brought close to the liquid inlet of the induction furnace, so that the molten aluminum flows into the induction furnace along the guide pipe 5.

[0049] The design was further optimized by setting the guide pipe 5 at an angle, with the higher end of the guide pipe 5 facing the cylinder 4 and the lower end of the guide pipe 5 facing the induction furnace.

[0050] Further optimization of the scheme: the drainage component includes a drainage column 6 rotatably connected inside the cylinder 4. The top surface of the drainage column 6 is provided with a threaded hole 8. A transmission rod is threadedly connected to the threaded hole 8. A motor 3 is connected to the end of the transmission rod away from the threaded hole 8. The motor 3 is fixedly connected to the top surface of the support plate 1.

[0051] When the drainage column 6 is severely worn and needs to be replaced, it can be easily disassembled through the threaded hole 8.

[0052] Motor 3 drives the transmission rod to rotate, and the transmission rod drives the diversion column 6 to rotate, so that the diversion column 6 can rotate stably inside the cylinder 4.

[0053] To further optimize the design, the drainage column 6 is provided with several spiral grooves 7 on the circumferential direction facing the inner wall of the cylinder 4, and the threads of the spiral grooves 7 are opposite to the threads of the threaded holes 8.

[0054] The spiral groove 7 on the guide column 6 has a thread that is opposite to that of the threaded hole 8. This not only allows the threaded hole 8 to separate from the transmission rod, but also allows the spiral groove 7 to drive the molten aluminum in the melting furnace to move upward along the spiral groove 7 when the guide column 6 rotates.

[0055] The design was further optimized by creating several spiral grooves 7 at equal intervals. This allows the molten aluminum to move effectively upwards along the spiral grooves 7.

[0056] The design was further optimized so that the top surface of the guide column 6 is flush with the bottom surface of the end of the guide pipe 5 that extends into the cylinder 4. This allows the molten aluminum to flow effectively into the guide pipe 5 after the spiral groove 7 moves the molten aluminum upward.

[0057] The design was further optimized so that the bottom surface of the guide column 6 is flush with the bottom surface of the cylinder 4. This allows the spiral groove 7 on the guide column 6 to effectively drive the molten aluminum in the melting furnace to move upward along the spiral groove 7.

[0058] Working process: When the molten aluminum in the smelting furnace needs to be transferred to the induction furnace, the furnace covers of the smelting furnace and the induction furnace are opened. Then, the piston end of the hydraulic cylinder 2 retracts, causing the support plate 1 to descend. The support plate 1 causes the cylinder 4 to extend into the smelting furnace. When the bottom of the cylinder 4 is close to the bottom of the smelting furnace, the hydraulic cylinder 2 stops working. At this time, the liquid outlet end of the guide pipe 5 approaches the liquid inlet of the induction furnace. Then, the motor 3 is turned on. The motor 3 drives the transmission rod to rotate, and the transmission rod drives the guide column 6 to rotate. The molten aluminum in the smelting furnace will move upward along the spiral groove 7. When the molten aluminum flows past the top surface of the guide column 6, the molten aluminum will flow into the guide pipe 5. The molten aluminum flows into the induction furnace through the guide pipe 5. When the guide pipe 5 stops flowing out of the molten aluminum, the furnace cover of the induction furnace is closed. At the same time, the piston end of the hydraulic cylinder 2 extends, so that the bottom of the cylinder 4 is above the smelting furnace. At this time, the next batch of molten aluminum can be produced.
