Description

Technical Field

[0001] This utility model belongs to the field of aluminum liquid conveying technology, and specifically relates to an aluminum liquid circulation guiding mechanism. Background Technology

[0002] In the aluminum processing industry, the circulation and transportation of molten aluminum is a crucial step. During the production of molten aluminum, in order to ensure the uniformity of the molten aluminum's quality and to smoothly transport the molten aluminum from the furnace to subsequent processing equipment (such as chutes), specialized mechanisms are needed to achieve the circulation and guiding of the molten aluminum.

[0003] Traditional methods of conveying molten aluminum typically rely on gravity or simple pumping devices, but these methods have many shortcomings. For example, gravity conveying makes it difficult to achieve efficient circulation and precise delivery of molten aluminum, and it cannot fully mix the molten aluminum in different locations within the furnace, resulting in uneven aluminum temperature. On the other hand, simple pumping devices have an unreasonable structural design, which may cause significant wear and tear on the conveying equipment during the transportation process, reducing the service life of the equipment, and the pumping efficiency is low, which cannot meet the needs of large-scale production.

[0004] Furthermore, existing aluminum molten metal pump assemblies also have some structural design problems. Some impellers lack lifting and lowering functions, making it difficult to flexibly adjust the impeller's depth in the molten aluminum according to actual production conditions. This significantly limits the pumping efficiency and adaptability. In actual production, the level of molten aluminum in the furnace changes continuously as production progresses. If the impeller lacks lifting and lowering functions, when the molten aluminum level drops, the impeller may be exposed above the liquid surface, resulting in the inability to pump molten aluminum normally or a significant decrease in pumping efficiency. Conversely, when the molten aluminum level rises, the impeller may be positioned too deep, increasing the load on the impeller, wasting energy, and potentially causing impeller damage.

[0005] In view of this, we propose an aluminum liquid circulation guiding mechanism that can improve the processing quality of subsequent aluminum products by adjusting the impeller height according to the aluminum liquid level and production needs. Utility Model Content

[0006] The present invention aims to solve the technical problem in the prior art where the impeller of the aluminum liquid pump cannot be adjusted according to the aluminum liquid level and production needs, which may lead to uneven stirring of the aluminum liquid during the pumping process, resulting in uneven distribution of temperature and composition of the aluminum liquid in the furnace, thereby affecting the quality of the aluminum liquid and consequently affecting the processing quality of subsequent aluminum products.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an aluminum liquid circulation guiding mechanism, comprising an aluminum liquid conveying tank and an aluminum liquid pump assembly, wherein the aluminum liquid conveying tank is used to guide and convey the aluminum liquid in the furnace to the chute; the aluminum liquid pump assembly is used to pump the aluminum liquid in the furnace into the chute after passing through the aluminum liquid conveying tank, for circulating the aluminum liquid in the furnace or lifting the aluminum liquid for easy conveying.

[0008] An aluminum liquid outlet is located on the left rear side of the aluminum liquid conveying trough, leading to the chute; and an aluminum liquid inlet is located on the front right side of the aluminum liquid conveying trough, leading to the furnace.

[0009] The aluminum liquid pump assembly includes a lifting platform, a drive shaft rotatably mounted on the lifting platform, and an impeller fixed at the bottom of the drive shaft and extending into the pumping chamber of the aluminum liquid conveying trough; the aluminum liquid in the furnace is pumped into the chute by the rotation of the impeller.

[0010] Preferably, the direction of the aluminum liquid inlet is perpendicular to the direction of the aluminum liquid outlet.

[0011] Preferably, the aluminum liquid outlet and aluminum liquid inlet are connected to the pumping chamber.

[0012] Preferably, the top of the aluminum liquid conveying tank is provided with three guide columns arranged in a triangular pattern, and the top of the three guide columns is provided with a fixed platform.

[0013] Preferably, a vertical lead screw is rotatably provided between the fixed platform and the aluminum liquid conveying tank. The lifting platform is connected to the vertical lead screw through a lead screw nut and the lifting platform slides through a sliding guide sleeve fixed on it in cooperation with three guide columns. A servo reduction motor that drives the vertical lead screw to rotate is provided on the top of the fixed platform.

[0014] The servo reducer motor drives the vertical lead screw to rotate, which in turn drives the lifting platform to move up or down, allowing the impeller to extend into or move away from the pumping chamber.

[0015] Preferably, the lifting platform is equipped with a sprocket box, and a large sprocket fixedly connected to the top of the drive shaft is installed in the sprocket box. The output shaft end of the drive motor fixedly installed at the top of the sprocket box is connected to the small sprocket in the sprocket box. The small sprocket and the large sprocket are driven by a chain.

[0016] The small sprocket is driven by a drive motor to rotate, and the small sprocket drives the large sprocket to rotate via a chain, which in turn drives the drive shaft and impeller to rotate, thereby enabling the impeller to pump the molten aluminum in the furnace into the chute.

[0017] Preferably, an arc-shaped protective cover is provided between the fixed platform and the aluminum liquid conveying tank to protect the vertical lead screw, and an arc-shaped guide hole is provided on the lifting platform to guide the sliding of the arc-shaped protective cover.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are:

[0019] In this aluminum liquid circulation guiding mechanism, the aluminum liquid inlet and outlet are vertically aligned, altering the flow direction of the aluminum liquid within the conveying tank. This avoids direct, linear impacts and effectively reduces wear on the tank walls. The aluminum liquid inlet is located slightly to the right of the front, and the outlet is slightly to the left and rear. This arrangement creates a rational flow path for the aluminum liquid within the conveying tank. This promotes aluminum liquid circulation, improves its uniformity, and consequently enhances the quality of subsequent aluminum products. The pumping chamber, serving as the working area of ​​the aluminum liquid pump assembly, connects the aluminum liquid inlet and outlet, effectively concentrating the impeller's pumping action within this area.

[0020] 2. Three guide columns arranged in a triangle provide stable guidance for the lifting platform. The stability of the triangle ensures that the lifting platform will not sway or deviate during the lifting process, ensuring that the impeller can accurately enter or leave the pumping chamber. The use of a screw drive provides high transmission accuracy and large load-bearing capacity, allowing precise control of the lifting platform's position and thus accurately adjusting the depth of the impeller within the pumping chamber. This enables the equipment to adapt to different aluminum liquid pumping needs, improving production flexibility and adaptability.

[0021] 3. The sprocket box provides a relatively enclosed working environment for the large and small sprockets, preventing splashing aluminum, dust, and other impurities from entering the sprocket drive system. This ensures the normal operation of the chain and sprockets, extends their service life, and reduces equipment maintenance costs. The arc-shaped protective cover, installed between the fixed platform and the aluminum molten material conveying tank, protects the vertical lead screw, preventing aluminum molten material from splashing onto it, avoiding high-temperature damage and corrosion from the aluminum molten material, extending the lead screw's service life, and ensuring the reliability of the lead screw drive.

[0027] 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.

[0028] The following combination Figures 1 to 4 This application will be described in further detail.

[0029] This application discloses an aluminum liquid circulation guiding mechanism, including an aluminum liquid conveying tank 1 and an aluminum liquid pump assembly. The aluminum liquid conveying tank 1 is used to guide and convey the aluminum liquid in the furnace to the chute; the aluminum liquid pump assembly is used to pump the aluminum liquid in the furnace into the chute after passing through the aluminum liquid conveying tank 1, for circulating the aluminum liquid in the furnace or lifting the aluminum liquid for easy conveying.

[0030] Aluminum liquid outlet 2 is located on the left rear of aluminum liquid conveying tank 1 to lead to the chute, and aluminum liquid inlet 3 is located on the front right of aluminum liquid conveying tank 1 to lead to the furnace. The direction of aluminum liquid inlet 3 is perpendicular to the direction of aluminum liquid outlet 2. A pumping chamber 4 is provided on aluminum liquid conveying tank 1, and aluminum liquid outlet 2 and aluminum liquid inlet 3 are respectively connected to pumping chamber 4.

[0031] The perpendicular orientation of the aluminum molten inlet and outlet alters the flow direction of the molten aluminum within the conveying tank, better guiding its flow and preventing direct linear impact during transport, thus reducing wear on the tank walls. Furthermore, the vertical inlet and outlet configuration allows for more efficient equipment layout within a limited space, improving space utilization.

[0032] The aluminum liquid inlet 3 is located at the front right side leading into the furnace, and the aluminum liquid outlet 2 is located at the left rear side leading into the chute. This arrangement allows the aluminum liquid to form a more reasonable flow path in the conveying trough, which is conducive to fully mixing the aluminum liquid in different positions in the furnace, promoting the circulation of the aluminum liquid, and improving the uniformity of the aluminum liquid.

[0033] The pumping chamber 4 serves as the working area of ​​the aluminum liquid pump assembly, connecting the aluminum liquid inlet 3 and outlet. This effectively concentrates the pumping action of the impeller 7 in this area, improving pumping efficiency and ensuring that the aluminum liquid can be stably and smoothly transported from the furnace to the chute.

[0034] The aluminum liquid pump assembly includes a lifting platform 5, a drive shaft 6 rotatably mounted on the lifting platform 5, and an impeller 7 fixed at the bottom of the drive shaft 6 and extending into the pumping chamber 4 on the aluminum liquid conveying trough 1; the aluminum liquid in the furnace is pumped into the chute by rotating the impeller 7.

[0035] The top of the aluminum liquid conveying tank 1 is provided with three guide columns 8 arranged in a triangular pattern, and the top of the three guide columns 8 is provided with a fixed platform 9. A vertical lead screw 10 is rotatably connected between the fixed platform 9 and the aluminum liquid conveying tank 1. The lifting platform 5 is connected to the vertical lead screw 10 through a lead screw nut 11, and the lifting platform 5 is slidably guided by the three guide columns 8 through a sliding guide sleeve 12 fixed on it. The top of the fixed platform 9 is provided with a servo reduction motor 13 that drives the vertical lead screw 10 to rotate.

[0036] The servo reducer motor 13 drives the vertical lead screw 10 to rotate, thereby driving the lifting platform 5 to rise and fall, so that the impeller 7 extends into or away from the pumping chamber 4.

[0037] Three guide columns 8 are arranged in a triangular pattern at the top of the aluminum liquid conveying tank 1, providing stable guidance for the lifting platform 5. The triangle shape ensures stability, preventing the lifting platform 5 from swaying or shifting during lifting, and ensuring the impeller 7 accurately enters or leaves the pumping chamber 4, thus improving the equipment's operational accuracy. The fixed platform 9 provides the mounting base for the vertical lead screw 10 and the servo geared motor 13, ensuring the stability of the entire lifting system. Simultaneously, it works with the guide columns 8 to further enhance the overall structural strength of the equipment. The lifting platform 5 is connected to the vertical lead screw 10 via the lead screw nut 11. The lead screw drive features high transmission accuracy and high load-bearing capacity. It can precisely control the lifting position of the lifting platform 5, thereby accurately adjusting the depth of the impeller 7 within the pumping chamber 4 to adapt to different aluminum liquid pumping requirements. The servo geared motor 13 has precise speed regulation and positioning functions, allowing flexible control of the rotation speed and direction of the vertical lead screw 10 according to actual production needs, thus achieving precise lifting of the lifting platform 5. This not only improves the automation level of the equipment but also effectively avoids errors caused by manual operation.

[0038] The lifting platform 5 is equipped with a sprocket box 14. A large sprocket fixedly connected to the top of the drive shaft 6 is installed in the sprocket box 14. The output shaft end of the drive motor 15 fixedly installed on the top of the sprocket box 14 is connected to the small sprocket in the sprocket box 14. The small sprocket and the large sprocket are driven by a chain.

[0039] The small sprocket is driven to rotate by the drive motor 15. The small sprocket drives the large sprocket to rotate through the chain, which in turn drives the drive shaft 6 and the impeller 7 to rotate. Thus, the impeller 7 pumps the aluminum liquid in the furnace into the chute.

[0040] The sprocket box 14 provides a relatively enclosed working environment for the large and small sprockets, preventing splashes of molten aluminum, dust, and other impurities from entering the sprocket drive system. This ensures the normal operation of the chain and sprockets and extends their service life. Chain drives have advantages such as high transmission efficiency, simple structure, and low cost. The small sprocket is driven by the drive motor 15, which in turn drives the large sprocket via the chain, thereby rotating the drive shaft 6 and the impeller 7. This effectively transmits the power of the drive motor 15 to the impeller 7, achieving the pumping of molten aluminum. Simultaneously, the chain drive can buffer and absorb vibration to a certain extent, reducing noise and impact during equipment operation.

[0041] An arc-shaped protective cover 16 is provided between the fixed platform 9 and the aluminum liquid conveying tank 1 to protect the vertical lead screw 10. An arc-shaped guide hole 17 is provided on the lifting platform 5 to guide the sliding of the arc-shaped protective cover 16.

[0042] An arc-shaped protective cover 16 is installed between the fixed platform 9 and the aluminum liquid conveying tank 1 to protect the vertical lead screw 10. High temperatures and splashing occur during aluminum liquid conveying; the protective cover prevents aluminum liquid from splashing onto the lead screw, avoiding damage from high temperatures and corrosion from the aluminum liquid, extending the lead screw's service life, and ensuring the reliability of the lead screw drive. An arc-shaped guide hole 17 on the lifting platform 5 cooperates with the arc-shaped protective cover 16 for guiding sliding, further enhancing the stability and guidance of the lifting platform 5 during lifting. During lifting, the arc-shaped guide hole 17 slides along the arc-shaped protective cover 16, effectively limiting the lateral displacement of the lifting platform 5 and ensuring that the impeller 7 is accurately aligned with the pumping chamber 4.

[0043] In this aluminum liquid circulation guiding mechanism, the aluminum liquid inlet 3 and outlet are set perpendicularly, changing the flow direction of the aluminum liquid, avoiding straight-line impact, effectively reducing wear on the conveying tank wall, extending the service life of the conveying tank, and reducing equipment replacement costs. The aluminum liquid inlet 3 is located slightly to the right front, and the outlet is located slightly to the left rear, allowing the aluminum liquid to form a reasonable flow path within the conveying tank, promoting aluminum liquid circulation within the furnace, improving the uniformity of the aluminum liquid, and thus enhancing the quality of subsequent aluminum products.

[0044] In existing technologies, the impeller 7 may lack a stable lifting guide structure, making it prone to swaying or deviation during lifting. This mechanism provides stable guidance for the lifting platform 5 through three triangularly arranged guide columns 8. The stability of the triangle ensures that the lifting platform 5 will not sway, ensuring that the impeller 7 accurately enters or moves away from the pumping chamber 4, improving equipment operating accuracy and guaranteeing the accuracy of aluminum liquid pumping. The fixed platform 9 provides a mounting base for the vertical lead screw 10 and servo geared motor 13, further enhancing the overall structural strength of the equipment in conjunction with the guide columns 8. Compared to some loosely structured existing equipment, this mechanism is more stable and reliable during operation, can withstand greater workloads, and reduces the probability of failures due to structural instability.

[0045] Traditional equipment may struggle to precisely control the depth of the impeller 7 within the pumping chamber 4. This mechanism employs a screw drive, offering high transmission precision and load-bearing capacity. It can precisely control the lifting position of the lifting platform 5 and accurately adjust the depth of the impeller 7 to adapt to different aluminum liquid pumping requirements, thereby improving production flexibility and adaptability. The servo geared motor 13 has precise speed regulation and positioning functions, allowing for flexible control of the rotation of the vertical screw 10 according to actual production needs, achieving precise lifting of the lifting platform 5. This not only reduces manual operation and improves the automation level of the equipment but also avoids errors caused by manual operation, ensuring the stability and consistency of the production process.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
