Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for aluminum smelting, and in particular to a vacuum tube coiling device. Background Technology

[0002] In the aluminum electrolysis production process, a vacuum aluminum tapping machine is needed to extract high-temperature molten aluminum from the electrolytic cell to a ladle. During this process, the vacuum aluminum tapping machine is connected to the ladle via a vacuum tube, removing gas from the ladle to create negative pressure, thereby enabling the aluminum tapping operation. However, in practical applications, we have found that this optimized solution still has a pressing practical problem to be solved: the storage and convenient management of the vacuum tube.

[0003] To accommodate the relative positions of different electrolytic cells and ladle, and to facilitate equipment transfer after aluminum tapping, the vacuum tube connecting the vacuum tapping machine and the ladle needs to be of considerable length. Currently, this long tube is typically coiled haphazardly on the ground or simply suspended, which presents the following significant drawbacks: 1. Before and after each aluminum extraction operation, it is necessary to manually drag and coil this heavy and potentially hot vacuum tube, which is time-consuming and labor-intensive and affects the efficiency of the operation. 2. Vacuum tubes that are placed haphazardly are easily stepped on by vehicles or people or scratched by sharp objects, which can cause wear and tear and breakage of the tubes. This not only shortens their service life but may also damage the vacuum seal, affect the aluminum extraction effect, and even cause leakage risks. 3. The scattered piping makes the work site messy. Furthermore, when the vacuum aluminum tapping machine needs to be moved, the scattered piping becomes an obstacle, reducing the overall flexibility and ease of movement of the equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problems of cumbersome operation of vacuum tube winding and unwinding, chaotic on-site management, and easy wear and damage of the pipeline in the existing vacuum aluminum tapping machine, and to propose a vacuum tube winding and coiling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vacuum tube coiling device includes a coiling wheel, the coiling wheel including a central shaft, spokes and a support base, the spokes being used to support and coil the vacuum tube; The central shaft has an inner cavity, and an exhaust pipe communicating with the inner cavity is provided on the central shaft. The exhaust pipe is used to connect one end of the vacuum tube.

[0006] In some embodiments, the support base rotatably supports the central shaft via bearings; the support base is provided with a fixed frame independent of the equipment, and the coil wheel is placed on the ground via the fixed frame; or the coil wheel is integrated with the equipment, and the coil wheel is located on the side, top, or bottom of the equipment.

[0007] In some embodiments, the exhaust pipe is rotatably connected to the air inlet of the device via a seal; the seal is a packing seal or a mechanical seal.

[0008] In some embodiments, the seal is disposed at the air inlet of the device; or the seal is disposed at the exhaust pipe of the coil wheel.

[0009] In some embodiments, the seal includes a base and an end cap; The base is fixedly installed, and the end cap is movably sleeved on the circumference of the exhaust pipe. The base and the end cap are connected by fasteners. The base is equipped with packing or a mechanical seal. The end cap is provided with a compression ring on the side near the base. When the end cap is fastened to the base, the compression ring presses against the packing or mechanical seal for sealing.

[0010] In some embodiments, the coil wheel is driven manually; or the coil wheel is driven by a rotating assembly.

[0011] In some embodiments, the rotating assembly includes a drive motor that drives the disc wheel to rotate via a transmission unit; the drive object of the transmission unit is a central shaft or a wheel spoke.

[0012] In some embodiments, when the transmission unit drives the central shaft, the transmission method is friction transmission or meshing transmission; The friction drive is a transmission of force through friction between the belt and the pulley fixed on the central shaft; The meshing transmission is a transmission between a chain and a gear fixed on a central shaft, or between a synchronous belt and a synchronous pulley.

[0013] In some embodiments, when the transmission unit drives the wheel spokes, the transmission method is friction transmission or meshing transmission; The friction drive is achieved by pressing the outer side of the wheel spokes with a rotating wheel, thereby utilizing frictional force for transmission; The meshing transmission is a transmission through the meshing between a gear and a ring rack disposed on the outer side of the spokes.

[0014] Compared with the prior art, the present invention provides a vacuum tube coiling device, which has the following beneficial effects.

[0015] 1.

[0016] 2. This utility model has both manual and electric drive modes. In actual use, operators can more easily control the rotation of the coil wheel manually or by driving the motor as needed to quickly complete the vacuum tube loading and unloading operations, which greatly reduces labor intensity and improves the preparation and finishing efficiency of aluminum extraction operations.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-10 A vacuum tube winding and coiling device includes a coiling wheel 1, which is rotatably connected to a vacuum aluminum output machine 6 for winding up vacuum tubes.

[0033] The coil wheel 1 can be integrated with the vacuum aluminum tapping machine 6; or the coil wheel 1 can be fixedly connected to the vacuum aluminum tapping machine 6 via the fixing frame 2 on both sides, or it can be placed separately on the ground via the fixing frame 2 and used in conjunction with the vacuum aluminum tapping machine 6.

[0034] The coil wheel 1 includes a central shaft 101, and spokes 102 are provided on the outer side of the central shaft 101. The spokes 102 provide a limit for the vacuum tube to prevent the vacuum tube from coming out, and at the same time provide support for the vacuum tube. When the vacuum tube is wound up, the body of the vacuum tube is coiled in the space of the spokes 102.

[0035] A support base 5 is provided between the coil wheel 1 and the vacuum aluminum tapping machine 6; Support base 5 includes bearing 503 connected to coil wheel 1; Optionally, the support base 5 also includes a bottom ring 501 and a top ring 502. The bottom ring 501 and the top ring 502 are respectively provided with threaded holes at both ends, and the bottom ring 501 and the top ring 502 are fixedly connected by bolts; the outer ring of the bearing 503 is fixed between the bottom ring 501 and the top ring 502. The end of the central shaft 101 is fixedly connected to the inner ring of the bearing 503; The central shaft 101 has an inner cavity 401, and an exhaust pipe 402 communicating with the inner cavity 401 is provided on one side of the central shaft 101. The exhaust pipe 402 is used to connect to one end of the vacuum tube. When the coil wheel 1 rotates to retract or extend the vacuum tube, the vacuum tube maintains normal gas flow.

[0036] The air inlet 601 and exhaust pipe 402 of the vacuum aluminum tapping machine 6 are rotatably connected by a seal to prevent gas leakage. The seal is either a mechanical seal or a packing seal. The seal is located at the air inlet 601 of the equipment or at the exhaust pipe 402 of the coil wheel 1.

[0037] For example, the sealing element includes a base 602 located on one side of the air inlet 601, an end cap 603 movably connected to the exhaust pipe 402 in the circumferential direction, the end cap 603 sliding horizontally along the exhaust pipe 402, and threaded holes on the base 602 and the end cap 603 for fixing by bolts; the base 602 is provided with a packing 604 or a mechanical seal inside, the packing 604 being wound axially along the exhaust pipe 402; the end cap 603 is provided with a compression ring 605 on the side near the base 602 that matches the inner diameter of the base 602, when the compression ring 605 is mated with the base 602, it presses the packing 604 or the mechanical seal to improve the sealing performance.

[0038] When using mechanical seals, standardized shaft mechanical seals known in the art can be selected. The stationary ring portion can be fixedly connected to the base 602 or the equipment inlet 601 via a flange, while the rotating ring portion is fixedly connected to the exhaust pipe 402 and rotates with it, achieving dynamic sealing through the spring-preloaded sealing end face.

[0039] In this invention, the vacuum tube is connected to the air inlet pipe 4. By rotating the coil wheel 1, the end of the vacuum tube near the central shaft 101 rotates synchronously with the central shaft 101, thereby winding and unwinding the vacuum tube and controlling the length of the vacuum tube extending outward.

[0040] The power source for the coil wheel 1 can be manual, electric, or remotely controlled. By controlling the clockwise or counterclockwise rotation of the coil wheel 1, the vacuum tube can be wound and unwound.

[0041] For example, by holding the spokes 102 and pushing, the coil wheel 1 can be rotated clockwise and counterclockwise to manually wind and unwind the vacuum tube.

[0042] As another way of rotating the coil wheel 1, the coil wheel 1 can be driven to rotate by the rotating component 3 to achieve automatic winding and unwinding, which is more labor-saving and convenient.

[0043] The rotating assembly 3 is used to control the rotation of the coil wheel 1 to wind up the vacuum tube by directly or indirectly driving the central shaft 101 or the spokes 102.

[0044] Specifically, the rotating component 3 includes a drive motor 304, which directly drives the central shaft 101 or the spokes 102 to rotate via a transmission unit.

[0045] As one embodiment of the transmission unit driving the central shaft 101 (not shown), the transmission unit includes a drive gear 305 fixedly connected to the rotating end of the drive motor 304, a chain, and external teeth provided on the central shaft 101. After the drive motor 304 is started, the drive gear 305 drives the central shaft 101 to rotate through the cooperation of the chain and the external teeth.

[0046] As another embodiment of the transmission unit driving the central shaft 101 (not shown), the transmission unit includes a drive wheel and a belt fixedly connected to the rotating end of the drive motor 304. The end of the belt away from the drive wheel is located on the central shaft 101. Utilizing the friction between the belt and the central shaft 101, the central shaft 101 is driven to rotate after the drive motor 304 is started.

[0047] As one embodiment of the transmission unit for the transmission of the spokes 102, the transmission unit includes a drive motor 304 located at the bottom of the fixed frame 2 and a support plate 301 fixedly connected to the fixed frame 2. A connecting shaft 302 is rotatably connected between the two support plates 301, and a rubber wheel 303 corresponding to the outer side of the spokes 102 is provided on the connecting shaft 302.

[0048] A transmission gear 306 is provided on the circumferential direction of the connecting shaft 302. The transmission gear 306 is connected to the drive gear 305 at the rotating end of the drive motor 304 via a synchronous belt 307. After the drive motor 304 is started, it drives the connecting shaft 302 and the rubber wheel 303 to rotate via the synchronous belt 307. The friction between the rubber wheel 303 and the outer side of the spoke 102 drives the spoke 102 to rotate. By controlling the rotation direction of the drive motor 304, the clockwise and counterclockwise rotation direction of the rotating coil wheel 1 is controlled, thereby realizing the automatic winding and unwinding of the vacuum tube.

[0049] As another embodiment of the transmission unit driving the spokes 102 (not shown), an annular gear ring is fixedly installed on the outer periphery of the spokes 102. The transmission unit includes a drive gear fixedly connected to the output shaft of the drive motor 304. After the drive motor 304 is started, the drive gear meshes with the annular gear ring, driving the entire coil wheel 1 to rotate.

[0050] In another embodiment (not shown) of the transmission unit driving the spokes 102, a rim is provided on the outer edge of the spokes 102. The transmission unit includes a drive motor 304 and a transmission belt. A pulley is provided on the rotating end of the drive motor 304, and the transmission belt is tensioned and sleeved on the pulley and the rim. After the drive motor 304 is started, the friction force generated by the transmission belt directly drives the spokes 102 to rotate, thereby realizing the winding and unwinding of the vacuum tube.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
