[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0018] This utility model embodiment provides an automatic aluminum molten metal conveying screw pump, such as... Figure 1-2 As shown, the automatic aluminum molten material conveying screw pump includes: a pump base 1; a first mounting base 2 bolted to the pump base 1; a support frame 3 mounted to the first mounting base 2 via a pin, with a second mounting base 4 fixed on the support frame 3; a mounting base 5 fixed on the second mounting base 4, with an Archimedes screw 16 mounted on the mounting base 5 via a first bearing seat 6 for conveying aluminum molten material in the electrolytic cell; and a drive mechanism mounted on the mounting base 5 for driving the Archimedes screw 16 to rotate.
[0019] In this embodiment, the spiral pump is placed at a suitable position next to the electrolytic cell, so that one end of the Archimedes spiral 16 is inserted into the molten aluminum in the electrolytic cell. The drive mechanism is started, and the drive mechanism drives the Archimedes spiral 16 to rotate. Utilizing the spiral structure characteristics of the Archimedes spiral 16, the molten aluminum in the electrolytic cell is transported along the spiral channel to a designated position, such as the preheating aluminum ladle.
[0020] This automatic aluminum molten material conveying screw pump effectively reduces safety risks, preventing operators from being burned by manually scooping molten aluminum. It also reduces the operator's exposure to high temperatures, dust, and harmful gases, ensuring the operator's health. It reduces labor intensity, eliminating the need for manual scooping of molten aluminum with long-handled spoons or other tools, and the automatic conveying method improves the efficiency of molten aluminum transfer. Compared to manual operation, automatic conveying reduces human interference, making the quality control during molten aluminum transfer easier.
[0021] In a further preferred embodiment of this utility model, the driving mechanism includes: a second bearing seat 8 fixed on the mounting base 5; a transmission rod 7 assembled on the second bearing seat 8, one end of the transmission rod 7 being fixedly connected to the Archimedes screw 16 via a coupling; a reducer 9 fixed on the mounting base 5, the output shaft of the reducer 9 being fixedly connected to the transmission rod 7 via a coupling; and a pneumatic motor 10 fixed on the mounting base 5, the output shaft of the pneumatic motor 10 being fixedly connected to the input shaft of the reducer 9 via a coupling.
[0022] In this embodiment, the pneumatic motor 10 is started, and the pneumatic motor 10 outputs power, which is transmitted to the input shaft of the reducer 9 through the coupling. After the reducer 9 reduces the power and increases the torque, the power is transmitted to the transmission rod 7 through the coupling from its output shaft. The transmission rod 7 rotates stably under the support of the second bearing seat 8, and drives the Archimedes screw 16 connected to it to rotate, thereby realizing the automatic conveying of aluminum water in the electrolytic cell.
[0023] The drive mechanism uses a combination of components such as a pneumatic motor 10, a reducer 9, and a transmission rod 7 to form a stable power transmission path, ensuring that the Archimedes screw 16 receives continuous and stable driving force. The second bearing seat 8 provides reliable support for the transmission rod 7, ensuring the smoothness of the transmission process, reducing component wear, and extending the service life of the equipment. Thirdly, the power can be adjusted by the reducer 9, allowing the speed of the Archimedes screw 16 to be adjusted according to actual needs, making the aluminum molten material conveying process more flexible and facilitating the control of conveying efficiency and quality. At the same time, the application of the pneumatic motor 10 is more suitable for the high-temperature and dusty environment of aluminum molten material operation compared with traditional drive methods, ensuring stable operation of the equipment.
[0024] In a further preferred embodiment of the present invention, a third mounting base 11 is fixedly installed on the top of the pump base 1, and a first cylinder 12 is mounted on the third mounting base 11 via a pin. The output rod of the first cylinder 12 is hinged to the support frame 3.
[0025] In this embodiment, when the output rod of the first cylinder 12 extends or retracts, it drives the support frame 3, which is hinged to it, to rotate around the pin on the first mounting base 2. Since the second mounting base 4, mounting base 5, and other components are fixed on the support frame 3, the angle of the Archimedes screw 16 can be adjusted, allowing it to adjust the angle and depth of insertion into the molten aluminum according to the actual position and height of the molten aluminum in the electrolytic cell.
[0026] The angle of the Archimedes screw 16 can be easily adjusted by the first cylinder 12, reducing labor intensity and improving operational safety. It can flexibly adapt to different electrolytic cell conditions. Whether it is a change in the aluminum liquid level or a difference in the shape of the electrolytic cell, the attitude of the screw pump can be adjusted by the first cylinder 12 to ensure the effective delivery of aluminum liquid. The hinged and assembled method of the first cylinder 12 with other components ensures that the adjustment process is smooth and will not cause impact on the overall equipment structure, ensuring the stability and reliability of the equipment operation and extending the service life of the equipment.
[0027] In a further preferred embodiment of the present invention, a fourth mounting base 13 is fixedly installed on the support frame 3, a second cylinder 14 is mounted on the fourth mounting base 13 via a pin, a fifth mounting base 15 is mounted on the output rod of the second cylinder 14 via a pin, and the fifth mounting base 15 is fixedly connected to the mounting base 5.
[0028] In this embodiment, controlling the intake or exhaust of the second cylinder 14 causes its output rod to extend or retract. When the output rod extends or retracts, it drives the fifth mounting base 15, which is hinged to it, to move. Since the fifth mounting base 15 is fixed to the mounting base 5, and the mounting base 5 is equipped with the Archimedes spiral 16 and a drive mechanism, fine-tuning of the position and angle of the mounting base 5 can be achieved. Combined with the angle adjustment of the support frame 3 by the first cylinder 12, the attitude and position of the Archimedes spiral 16 within the electrolytic cell can be controlled more flexibly and precisely.
[0029] In a further preferred embodiment of the present invention, a transfer bag 17 is provided on one side of the pump base 1, and the transfer bag 17 is used to collect molten aluminum.
[0030] In this embodiment, since the transfer bag 17 is located on one side of the pump base 1, the molten aluminum is transported by the screw pump and flows directly into the transfer bag 17 for subsequent transfer of the molten aluminum.
[0031] In a further preferred embodiment of the present invention, the outer surface of the Archimedes spiral 16 is coated with a high-temperature resistant and non-stick coating, which is a silicon carbide ceramic coating.
[0032] In this embodiment, when the Archimedes screw 16 rotates to transport molten aluminum, the silicon carbide ceramic coating on its outer surface comes into play. Due to its high-temperature resistance, the coating protects the screw body from high-temperature corrosion in the high-temperature molten aluminum environment, maintaining the stability of the screw structure. Simultaneously, its anti-stick properties prevent molten aluminum from adhering to the screw surface, ensuring smooth transport of the molten aluminum along the screw channel. This allows the molten aluminum to flow smoothly from the electrolytic cell into the transfer bag 17 via the screw pump, completing the entire transport process.
[0033] In a further preferred embodiment of the present invention, an anti-slip pad is provided at the bottom of the pump base 1, and the anti-slip pad is made of rubber.
[0034] In this embodiment, the pump base 1 equipped with an anti-slip mat is placed on the working surface. The rubber anti-slip mat, due to its softness and high friction, maintains close contact with the ground. When the Archimedes screw 16 rotates to transport molten aluminum, the vibration generated by the equipment and the forces exerted during operation are transmitted to the anti-slip mat through the pump base 1. The anti-slip mat, relying on its own anti-slip properties, increases the friction with the ground, preventing the pump base 1 from sliding or shifting on the ground, thus ensuring the stability of the entire molten aluminum conveying screw pump during operation.
[0035] In summary, compared with related technologies, the automatic conveying of molten aluminum via the Archimedes spiral 16 and drive mechanism reduces safety risks and labor intensity while improving transfer efficiency. The first cylinder 12 and the second cylinder 14 work together to adjust the spiral posture to adapt to different working conditions. The transfer bag 17 simplifies the molten aluminum collection process. The silicon carbide ceramic coating protects the Archimedes spiral 16 and ensures smooth conveying. The rubber anti-slip pad ensures the stability of the pump base 1. Overall, these technologies effectively solve the drawbacks of manual transfer of molten aluminum and improve the safety, efficiency, and stability of molten aluminum transfer.
