Description

Technical Field

[0001] This utility model belongs to the field of crucible cleaning technology, and in particular relates to a device for cleaning the inside of a negative electrode material crucible. Background Technology

[0002] Anode material crucibles are containers used for melting and refining liquid metals, as well as for solid-liquid heating and reactions. Crucibles are high-temperature resistant containers widely used in scientific experiments and industrial production. They come in a variety of materials and types, and specific specifications must be followed when using them to ensure safety and efficiency.

[0003] An existing patent (publication number: CN206997299U) discloses a quartz crucible cleaning device, including a workbench. The upper surface of the workbench has a through hole in the center. Two sets of clamps are spaced apart on one side of the upper surface of the workbench. An electric telescopic rod is fixed on the other side of the upper surface of the workbench. A sleeve is rotatably connected to the inner cavity of the through hole through a hinge. A support plate is vertically welded to the bottom end face of the sleeve. A water inlet pipe is inserted into the inner cavity of the sleeve through a bearing.

[0004] The aforementioned comparative documents have the effect of cleaning the inner and outer walls of the crucible. However, the automatic loading and unloading of the crucible and the process of picking up and placing the crucible still require manual operation. Since the crucible has a certain weight, manual handling greatly increases the workload of workers and leads to increased labor intensity. Therefore, a negative electrode material crucible internal cleaning device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an internal cleaning device for negative electrode material crucibles, which has the advantages of automatic loading and unloading, automatic and efficient crucible collection and cleaning, and reduced manual labor intensity. This solves the problem pointed out in the aforementioned comparative documents that manual handling greatly increases the workload of workers and leads to increased manual labor intensity.

[0006] To achieve the above objectives, this application provides the following technical solution: a cleaning device for the inside of a negative electrode material crucible, comprising a cleaning tank, a support frame fixedly connected to the outer surface of the cleaning tank, a lifting drive device provided at the top of the support frame, a horizontal push drive device fixedly connected to the back of the lifting drive device, a connecting frame fixedly connected to the output end of the horizontal push drive device, a first drive mechanism fixedly installed on the outer surface of the connecting frame, a clamping mechanism threadedly connected to the output end of the first drive mechanism, the clamping mechanisms being symmetrically arranged outside the first drive mechanism, a second drive mechanism fixedly installed at the bottom of the cleaning tank, a cleaning brush mechanism threadedly connected to the output of the second drive mechanism, a rotating device engaged on one side of the second drive mechanism, the top of the rotating device extending into the interior of the cleaning tank, and a nozzle fixedly connected to the inner wall of the cleaning tank.

[0007] With the above scheme, when the negative electrode material crucible needs to be cleaned, the first drive mechanism drives the clamping mechanism to move towards the center to clamp the crucible. At this time, the horizontal push drive mechanism extends and retracts, causing the connecting frame to reset, so that the clamping mechanism and the crucible are located above the cleaning position inside the cleaning tank, thus realizing the automatic material handling process. In conjunction with the lifting drive device, the connecting frame and the horizontal push drive device move downward together to place the crucible on the top of the operating device. At this time, the second drive mechanism drives the cleaning mechanism to rotate to clean the crucible, while driving the operating device to rotate the crucible on the inner wall of the clamping mechanism. This combination achieves a rapid cleaning effect. After cleaning, the lifting drive device drives the horizontal push drive device to rise in the opposite direction, and then the horizontal push drive device pushes the clamping mechanism to move to the outside of the cleaning tank and unfolds to both sides to loosen, thus completing the automatic unloading process. This realizes automatic loading and unloading of crucibles for automatic and efficient cleaning, reducing the intensity of manual labor.

[0008] Furthermore, the lifting drive device includes a lifting cylinder, the output end of which is provided with a telescopic drive shaft, one end of which is fixedly connected to a lifting frame, and the inner wall of the support frame is fixedly connected to a limit rod, the lifting frame passing through the outside of the limit rod and slidably connected to it.

[0009] The above scheme uses a lifting cylinder to drive the telescopic drive shaft to extend and retract, thereby driving the lifting frame to rise and fall along the vertical direction of the support frame. This provides a lifting drive source for components such as the horizontal push drive device and the connecting frame, indirectly enabling the clamping mechanism to flexibly lift and lower the crucible to pick it up.

[0010] Furthermore, the horizontal push drive device includes a horizontal push cylinder, the output end of which is provided with a horizontal push shaft, the horizontal push cylinder is fixedly connected to the outside of the lifting frame, the first drive mechanism includes a first drive motor, the output end of which is fixedly connected to a threaded shaft, and the clamping mechanism passes through the outside of the threaded shaft and is threadedly connected to it.

[0011] Through the above scheme, the horizontal push cylinder and the horizontal push shaft work together to make the forward and reverse extension of the horizontal push shaft push the connecting frame to move laterally. In this way, the first drive motor and the clamping mechanism on the threaded shaft can move laterally together to achieve the effect of moving laterally to collect or place the crucible.

[0012] Furthermore, the clamping mechanism includes a spring clamping plate, a back plate is fixedly connected to the back of the spring clamping plate, a threaded plate is fixedly connected to the top of the spring clamping plate, the threaded plate passes through the outside of the threaded shaft and is threadedly connected to it, an inner limiting rod is fixedly installed on the inner wall of the connecting frame, and the threaded plate passes through the inner limiting rod and is slidably connected to it.

[0013] With the above scheme, after the horizontal push shaft drives the connecting frame to move to the appropriate position, the first drive motor starts the drive threaded shaft to rotate. The two sides of the threaded shaft have opposite threads, which can drive the two sets of threaded plates to move closer or further apart outside the threaded shaft. Together with the spring clamping plate, it provides clamping and loosening effect for the crucible, realizing the automatic clamping, picking up and loosening of materials during the crucible cleaning process, thereby reducing manual labor. The inner limit rod can provide a limiting effect for the displacement of the threaded plate.

[0014] Furthermore, the second drive mechanism includes a second drive motor, and a drive gear is fixedly installed at the output end of the second drive motor. The cleaning mechanism includes a cleaning frame, and cleaning brushes are arrayed on the outer surface of the cleaning frame. The cleaning frame is sleeved on the output shaft end of the second drive motor.

[0015] With the above scheme, when the crucible is placed on top of the operating device, the second drive motor and the drive gear work together to drive the cleaning brush frame and the cleaning brush to rotate, so that the cleaning plug can continuously generate friction with the outer surface of the crucible to achieve a high-efficiency cleaning effect. At the same time, the drive gear provides synchronous driving force for the operating device.

[0016] Furthermore, the operating device includes a rotating gear, the driving gear meshing with the rotating gear, and a rotating platform fixedly mounted on the top of the rotating gear, the rotating platform extending into the interior of the cleaning tank.

[0017] With the above scheme, when the drive gear is running, it drives the rotating gear to rotate, which in turn drives the rotating platform and crucible at the top to rotate. This allows the cleaning brush to clean the crucible while the crucible rotates and changes its surface for cleaning, thereby improving cleaning efficiency.

[0018] Furthermore, a water outlet pipe is fixedly installed at the bottom of the cleaning tank, and a baffle plate is provided at the top of the cleaning tank.

[0019] The above solution provides a convenient outlet pipe for wastewater inside the cleaning tank, allowing for timely discharge of the wastewater.

[0020] Furthermore, a receiving platform is fixedly installed on the outer surface of the cleaning tank.

[0021] With the above solution, the receiving platform can be close to the automatic conveying equipment. After the crucible is cleaned, the connecting frame is driven by the horizontal push shaft to move closer to the receiving platform, thereby driving the spring clamping plate to move closer to the top of the receiving platform, so as to temporarily store the crucible.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] 1. This internal cleaning device for negative electrode material crucibles, when cleaning is required, drives a first driving mechanism to move a clamping mechanism towards the center to clamp the crucible. Simultaneously, a horizontal pushing driving mechanism extends and retracts, resetting the connecting frame so that the clamping mechanism and crucible are positioned above the cleaning position inside the cleaning chamber, thus achieving automatic material handling. A lifting driving device extends and retracts, pushing the connecting frame and the horizontal pushing driving device downwards together to place the crucible on top of the operating device. A second driving mechanism then drives a cleaning mechanism to rotate, cleaning the crucible while simultaneously driving the operating device to rotate the crucible on the inner wall of the clamping mechanism, achieving rapid cleaning. After cleaning, the lifting driving device drives the horizontal pushing driving device to rise in the opposite direction, pushing the clamping mechanism to the outside of the cleaning chamber and then unfolding to both sides to complete the automatic unloading process. This achieves automatic loading and unloading of crucibles for efficient cleaning, reducing manual labor intensity.

[0024] 2. This internal cleaning device for a negative electrode material crucible, after the horizontal push shaft drives the connecting frame to move to the appropriate position, starts the drive threaded shaft to rotate via the first drive motor. The threaded shaft has opposite threads on both sides, enabling two sets of threaded plates to move closer or further apart outside the threaded shaft. This, combined with spring clamping plates, provides clamping and releasing effects for the crucible, achieving automatic clamping, picking up, and releasing during the crucible cleaning process. This reduces manual labor. The inner limit rod provides a limiting function for the displacement of the threaded plates.

[0025] 3. The internal cleaning device for a negative electrode material crucible, when the drive gear is running, drives the rotating gear to rotate, thereby causing the rotating platform and crucible at the top to rotate, so that while the cleaning brush cleans the crucible, the crucible can rotate and change its surface for cleaning, thereby improving the cleaning efficiency.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a negative electrode material crucible internal cleaning device includes a cleaning tank 1. A support frame 2 is fixedly connected to the outer surface of the cleaning tank 1. A lifting drive device 3 is provided on the top of the support frame 2. A horizontal push drive device 4 is fixedly connected to the back of the lifting drive device 3. A connecting frame 5 is fixedly connected to the output end of the horizontal push drive device 4. A first drive mechanism 6 is fixedly installed on the outer surface of the connecting frame 5. A clamping mechanism 7 is threadedly connected to the output end of the first drive mechanism 6. The clamping mechanisms 7 are symmetrically arranged outside the first drive mechanism 6. A second drive mechanism 8 is fixedly installed at the bottom of the cleaning tank 1. A cleaning brushing mechanism 9 is threadedly connected to the output of the second drive mechanism 8. A rotating device 10 is engaged on one side of the second drive mechanism 8. The top of the rotating device 10 extends into the interior of the cleaning tank 1. A nozzle 11 is fixedly connected to the inner wall of the cleaning tank 1. When it is necessary to clean the negative electrode material crucible, the first drive mechanism 6 drives the clamping mechanism 11. The holding mechanism 7 moves towards the center to clamp the crucible. At this time, the horizontal push drive device 4 extends and retracts, causing the connecting frame 5 to reset, so that the clamping mechanism 7 and the crucible are located above the cleaning position inside the cleaning tank 1, thus realizing the automatic material handling process. The lifting drive device 3 extends and retracts, pushing the connecting frame 5 and the horizontal push drive device 4 downward together to place the crucible on the top of the operating device 10. At this time, the second drive mechanism 8 drives the cleaning mechanism 9 to rotate to clean the crucible, while driving the operating device 10 to rotate, causing the crucible to rotate on the inner wall of the clamping mechanism 7. This combination achieves a rapid cleaning effect. After cleaning, the lifting drive device 3 drives the horizontal push drive device 4 to rise in the opposite direction, and then the horizontal push drive device 4 pushes the clamping mechanism 7 to move to the outside of the cleaning tank 1 and unfolds and loosens to both sides, thus completing the automatic unloading process. This realizes automatic loading and unloading of crucibles for automatic and efficient cleaning, reducing the intensity of manual labor.

[0034] Please see Figure 1 ,and Figure 2 The lifting drive device 3 includes a lifting cylinder 301. The output end of the lifting cylinder 301 is provided with a telescopic drive shaft 302. One end of the telescopic drive shaft 302 is fixedly connected to a lifting frame 303. A limit rod 12 is fixedly connected to the inner wall of the support frame 2. The lifting frame 303 passes through the outside of the limit rod 12 and is slidably connected to it. The lifting cylinder 301 drives the telescopic drive shaft 302 to extend and retract, thereby driving the lifting frame 303 to rise and fall along the vertical direction of the support frame 2. This provides a lifting drive source for components such as the horizontal push drive device 4 and the connecting frame 5, indirectly enabling the clamping mechanism 7 to flexibly lift and lower the crucible to pick it up.

[0035] Please refer to the figure. Figure 2 and Figure 3The horizontal push drive device 4 includes a horizontal push cylinder 401, and a horizontal push shaft 402 is provided at the output end of the horizontal push cylinder 401. The horizontal push cylinder 401 is fixedly connected to the outside of the lifting frame 303. The first drive mechanism 6 includes a first drive motor 601, and a threaded shaft 602 is fixedly connected at the output end of the first drive motor 601. The clamping mechanism 7 passes through the outside of the threaded shaft 602 and is threadedly connected to it. Under the cooperation of the horizontal push cylinder 401 and the horizontal push shaft 402, the forward and reverse extension of the horizontal push shaft 402 can push the connecting frame 5 to move laterally. Thus, the first drive motor 601 and the clamping mechanism 7 on the threaded shaft 602 can move laterally together to achieve the effect of laterally moving to collect or place the crucible.

[0036] Please see Figure 2 and Figure 4 The clamping mechanism 7 includes a spring clamping plate 701. A back plate 702 is fixedly connected to the back of the spring clamping plate 701, and a threaded plate 703 is fixedly connected to the top of the spring clamping plate 701. The threaded plate 703 passes through the outside of the threaded shaft 602 and is threadedly connected to it. An inner limit rod 13 is fixedly installed on the inner wall of the connecting frame 5. The threaded plate 703 passes through the inner limit rod 13 and is slidably connected to it. When the horizontal push shaft 402 drives the connecting frame 5 to move to an appropriate position, the first drive motor 601 starts the drive to rotate the threaded shaft 602. The two sides of the threaded shaft 602 have opposite threads, so that the two sets of threaded plates 703 can move closer or further away from each other outside the threaded shaft 602. Together with the spring clamping plate 701, they provide clamping and loosening effects for the crucible, realizing the automatic clamping, picking up and loosening of materials during the crucible cleaning process, thereby reducing manual labor. The inner limit rod 13 can provide a limiting effect for the displacement of the threaded plate 703.

[0037] Please see Figure 2 and Figure 5 The operating device 10 includes an operating gear 1011, a drive gear 802 meshing with the operating gear 1011, and a rotating platform 1012 fixedly mounted on the top of the operating gear 1011. The rotating platform 1012 extends into the interior of the cleaning tank 1. When the drive gear 802 operates, it drives the operating gear 1011 to rotate, thereby driving the rotating platform 1012 and the crucible to rotate. This allows the cleaning brush 902 to clean the crucible while the crucible rotates and changes its surface for cleaning, thereby improving cleaning efficiency.

[0038] In this embodiment, an internal cleaning device for a negative electrode material crucible uses a lifting cylinder 301 to drive a telescopic drive shaft 302 to extend and retract, thereby driving a lifting frame 303 to rise and fall along the vertical direction of the support frame 2. This provides a lifting drive source for components such as the connecting frame 5, indirectly enabling the spring clamping plate 701 to flexibly lift and lower to pick up the crucible. A horizontal push cylinder 401 drives a horizontal push shaft 402 to extend and retract, allowing the forward and reverse extension of the horizontal push shaft 402 to push the connecting frame 5 to move laterally. This allows the first drive motor 601 and the spring clamping plate 701 on its threaded shaft 602 to move laterally together, achieving the effect of laterally moving to collect or place the crucible. The first drive motor 601 drives the threaded shaft 602 to rotate, and the two sides of the threaded shaft 602 have opposite threads, driving two sets of threaded plates 703. The threads 602 move closer or further apart from each other, and the spring clamping plate 701 provides clamping and loosening for the crucible, realizing the automatic clamping, picking up and loosening of materials during the crucible cleaning process, thereby reducing manual labor. The inner limit rod 13 can provide a limiting function for the displacement of the threaded plate 703. When the drive gear 802 is running, it drives the cleaning brush 902 to rotate and clean the crucible. At the same time, it drives the rotating gear 1011 to rotate the rotating table 1012 and the crucible. The nozzle continuously sprays water to rinse the back of the crucible, so that while the cleaning brush 902 is cleaning the crucible, the crucible can rotate and change its surface for cleaning, improving cleaning efficiency. After cleaning, the wastewater is discharged through the water outlet pipe 14. The baffle plate 15 can reduce the occurrence of water splashing to the outside of the cleaning tank 1.

[0039] It should be noted that...

[0040] The working principle of the above embodiments is as follows:

[0041] The lifting cylinder 301 drives the telescopic drive shaft 302 to extend and retract, thereby driving the lifting frame 303 to rise and fall along the vertical direction of the support frame 2, providing a lifting drive source for components such as the connecting frame 5. The horizontal push cylinder 401 drives the horizontal push shaft 402 to extend and retract, pushing the connecting frame 5 to move laterally. After the horizontal push shaft 402 drives the connecting frame 5 to the appropriate position, the first drive motor 601 starts the drive threaded shaft 602 to rotate. The threaded shaft 602 has opposite threads on both sides, enabling it to drive two sets of threaded plates 703 to move in opposite directions outside the threaded shaft 602. The crucible is clamped or released by the spring clamping plate 701 when it moves closer or further away from the other side. When the crucible is placed on the top of the rotating table 1012, the second drive motor 801 and the drive gear 802 drive the cleaning brush frame 901 and the cleaning brush 902 to rotate, so that the cleaning brush 902 can continuously generate friction with the outer surface of the crucible. When the drive gear 802 is running, it drives the rotating gear 1011 to rotate, which in turn drives the rotating table 1012 and the crucible to rotate, so that the cleaning brush 902 can clean the crucible while the crucible can rotate and change its surface for cleaning.
