Description

Technical Field

[0001] The utility model relates to the technical field of powder conveying equipment, in particular to a mechanical overturning and unloading device. Background Art

[0002] Carbonization is one of the primary processing steps in producing positive and negative electrode materials. Carbonization can be achieved through high-temperature heat treatment or chemical reactions. High-temperature heat treatment is typically performed under an inert atmosphere, often in a closed furnace or at high temperatures. At high temperatures, the carbon atoms in the raw material rearrange, forming a graphite structure. The temperature and duration of carbonization directly affect the structure and performance of the positive and negative electrode materials. Chemical carbonization is also a common method, which involves adding a carbon source and heating the reaction to achieve carbonization.

[0003] Currently, mainstream manufacturers generally use protective gas roller kilns for carbonization. The saggers containing the materials are stacked into multiple layers and then enter the roller kiln. After passing through the heating, insulation, and cooling sections, they flow out to the carbonization external circulation line, where they are sorted and processed, and the materials are poured out by flipping. The flipping process requires effective position limiting of the saggers containing the materials. Existing flipping and unloading machines mostly achieve this through the combination of positioning cylinders and sensors. The limit reliability is low, and the saggers may fall off during the flipping process.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0037] The following is combined with Figure 1-8 The utility model is further described.

[0038] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0039] Reference Figures 1 to 5 The present invention provides a mechanical turning and unloading device for turning and unloading carbonized positive and negative electrode materials, which includes a closed shell 1, a frame 2, a turning mechanism 3 and a limiting mechanism 4. The frame 2, the turning mechanism 3 and the limiting mechanism 4 are all arranged in the closed shell 1. The closed shell 1 isolates the inside of the shell from the external environment, and can effectively reduce the dust of the material powder from drifting into the external environment when the sagger 6 is turned. The closed shell 1 is provided with an inlet 11 and an outlet (not shown in the figure). The sagger 6 enters the closed shell 1 from the inlet 11 during the transportation process, and leaves the closed shell 1 from the outlet after being turned and unloaded by the turning mechanism 3. The inlet 11 and the outlet are both provided with an openable and closable lifting door 13. When the sagger 6 enters the closed shell 1, the lifting door 13 is closed to achieve the closure of the closed shell 1. The frame 2 is used to install and support various components, and its specific structural form is not limited here. The turning mechanism 3 is mounted on the frame 2 and is used to turn the sagger 6 to achieve material dumping. The limiting mechanism 4 is used to position and limit the sagger 6 on the turning mechanism 3 to ensure smooth turning. The frame 2 is provided with a hopper 21, located below the turning mechanism 3, to receive material dumped from the sagger 6.

[0040] Reference Figures 3 to 5The turning mechanism 3 includes several rollers 31, a mounting plate 32 and a turning drive assembly 33. Several rollers 31 are rotatably arranged on the mounting plate 32 along the horizontal conveying direction of the sagger 6. Specifically, there are two mounting plates 32, and the two mounting plates 32 are symmetrically arranged. Several rollers 31 are rotatably arranged between the two mounting plates 32. Several rollers 31 cooperate with the mounting plates 32 on both sides to form a turning station; the turning drive assembly 33 is arranged on the frame 2, and the mounting plate 32 is connected to the turning drive assembly 33. The turning drive assembly 33 is used to drive the mounting plate 32 to turn over, thereby driving the rollers 31 and the sagger 6 on the rollers 31 to turn over.

[0041] The flipping drive assembly 33 includes a flipping motor 331, a rotating shaft 332 and a bearing 333. The flipping motor 331 is fixedly connected to the frame 2. One end of the rotating shaft 332 is connected to the output end of the flipping motor 331. The end of the rotating shaft 332 away from the flipping motor 331 is fixedly connected to the mounting plate 32. The bearing 333 is sleeved on the outer peripheral side of the rotating shaft 332 and fixedly connected to the frame 2. The mounting plate 32 is rotatably connected to the frame 2 through the rotating shaft 332 and the bearing 333.

[0042] In this embodiment, the rotating shaft 332 on only one side of the mounting plate 32 is connected to the flip motor 331, with the side equipped with the flip motor 331 being the driving side. During operation, the flip motor 331 is activated, driving the rotating shaft 332 to rotate relative to the frame 2, thereby causing the flip station to flip and unload the sagger 6 at the flip station. In other embodiments, the flip motor 331 can be installed on both sides of the rotating shaft 332, and the flip motors 331 on both sides can be used to synchronize the operation of the flip motors 331 to achieve flipping of the flip station.

[0043] Reference Figure 2 and Figure 5The frame 2 is also provided with a roller drive assembly 5, which is used to drive the roller shaft 31 to rotate, so as to realize the transmission of the sagger 6 on the overturning and unloading equipment. The roller drive assembly 5 includes a roller motor 51, a driving gear 511 and a main shaft 52. The roller motor 51 is slidably arranged on the frame 2, and the driving gear 511 is fixedly arranged at the end of the output shaft of the roller motor 51. The main shaft 52 is rotatably connected to the mounting plate 32. The end of the main shaft 52 is fixedly connected to a driven gear 521, and the driven gear 521 is meshed with the driving gear 511. The ends of the roller shaft 31 are fixedly connected to the first bevel gear 311, and the main shaft 52 is fixedly connected to the second bevel gear 522 corresponding to the first bevel gear 311. The first bevel gear 311 corresponds to the second bevel gear 522 and meshes with each other. When the roller motor 51 is started, it drives the driving gear 511 to rotate. The driven gear 521 rotates synchronously with the driving gear 511, thereby driving the main shaft 52 to rotate. The first bevel gear 311 on the main shaft 52 drives the second bevel gear 522 to rotate, thereby achieving synchronous rotation of the multiple rollers 31. The use of bevel gears for transmission effectively ensures the reliability of the roller 31 driving process and the precise transmission ratio.

[0044] In this embodiment, a mounting bearing is fixedly connected to the mounting plate 32 , and the main shaft 52 is fixedly connected to the mounting plate 32 via the mounting bearing; the roller motor 51 , the driving gear 511 and the driven gear 521 are all arranged on the driving side of the turning mechanism 3 .

[0045] Furthermore, the roller motor 51 is slidably mounted on the frame 2. Specifically, a slide cylinder 53 is fixedly connected to the frame 2, and the roller motor 51 is mounted on the slide cylinder 53. The slide cylinder 53 can drive the roller motor 51 to move axially along the roller shaft 31 toward or away from the main shaft 52. Before the flipping station performs the flipping action, the slide cylinder 53 drives the roller motor 51 to move away from the main shaft 52, so that the driving gear 511 and the driven gear 521 are disengaged; when the sagger 6 is tilted, the slide cylinder 53 drives the roller motor 51 to move toward the main shaft 52, so that the driving gear 511 and the driven gear 521 are engaged again. By arranging the slide cylinder 53 to drive the roller motor 51 to move, the possibility of mechanical failure caused by the flipping station driving the roller motor 51 to flip together during the flipping process can be effectively avoided.

[0046] Reference Figures 4 to 7The limiting mechanism 4 is used to position and limit the sagger 6 located on the turning mechanism 3. The limiting mechanism 4 includes a height limiting block 41, a horizontal positioning block 42, a horizontal limiting block 43 and a limiting drive assembly 44. The height limiting block 41 is arranged on the mounting plate 32 to limit the height direction of the sagger 6; the horizontal positioning block 42 is axially slidably arranged on the mounting plate 32 along the roller shaft 31 to position the sagger 6 and cooperate with the horizontal limiting block 43 to achieve the limitation of the sagger 6; the limiting drive assembly 44 is used to drive the horizontal positioning block 42 and the horizontal limiting block 43 to position and limit the sagger 6.

[0047] Specifically, the height limit block 41 is fixedly mounted on the mounting plate 32 and has a "7"-shaped structure. When the sagger 6 enters the turning mechanism 3, the height limit block 41 can fasten the sagger 6 in the height direction of the sagger 6, thereby limiting the height direction of the sagger 6. The horizontal positioning blocks 42 are arranged on both sides of the horizontal conveying direction of the sagger 6, and the horizontal positioning blocks 42 are located on the side of the turning mechanism 3 close to the bowl outlet. The horizontal limit blocks 43 are arranged on both sides of the conveying direction of the sagger 6, and are located on the side of the turning mechanism 3 close to the bowl inlet 11. In this embodiment, the horizontal positioning blocks 42 and the horizontal limit blocks 43 both have an "L"-shaped structure, and the length of the portion of the horizontal positioning block 42 extending into the roller conveyor is greater than the length of the portion of the horizontal limit block 43 extending into the roller conveyor. The two horizontal positioning blocks 42 and the two horizontal limit blocks 43 cooperate to respectively limit the four corners of the sagger 6 while also mechanically positioning the movement of the sagger 6.

[0048] Reference Figure 5 and Figure 8 The limit drive assembly 44 includes a limit motor 441, a pulling rack 443, and an elastic driving member. The limit motor 441 is fixedly arranged on the frame 2, and the pulling rack 443 is slidably connected to the frame 2. The output shaft of the limit motor 441 is fixedly connected to the limit gear 442, which is engaged with the pulling rack 443. A connecting plate 421 is fixedly connected between the horizontal positioning block 42 and the horizontal limit block 43. The pulling rack 443 is engaged with the connecting plate 421 on the side close to the connecting plate 421. The pulling rack 443 is used to pull the connecting plate 421 away from the flipping station, thereby driving the horizontal positioning block 42 and the horizontal limit block 43 to move away from the flipping station. The elastic driving member is used to drive the horizontal positioning block 42 and the horizontal limit block 43 to move toward the flipping station to limit the sagger 6.

[0049] Specifically, the side of the pulling rack 443 close to the connecting plate 421 is rotatably connected to the hook 444, and the hook 444 is a gravity self-resetting structure, that is, the hook 444 is always in a downward state without external force, and a hook portion 4211 is provided on the connecting plate 421. The hook 444 can hook with the hook portion 4211. When the limit motor 441 rotates to drive the pulling rack 443 to slide on the frame 2 in the direction away from the flipping station, the hook 444 pulls the hook portion 421 1 drives the connecting plate 421 to slide in the direction away from the flipping station, thereby driving the horizontal positioning block 42 and the horizontal limiting block 43 to move in the direction away from the flipping station; when the limiting motor 441 drives the pulling rack 443 to slide in the direction of clamping the flipping station, the hook 444 separates from the hooking portion 4211. At this time, the elastic driving member is elastically released, driving the horizontal positioning block 42 and the horizontal limiting block 43 to move toward the flipping station until the hook 444 is hooked on the hooking portion 4211 again.

[0050] The connection between the pulling rack 443 and the connecting plate 421 is achieved by setting a structural form in which the hook 444 cooperates with the hook portion 421. When flipping at the flipping station, the pulling rack 443 can be disengaged from the connecting plate 421 without interfering with the flipping action.

[0051] In this embodiment, the top of the rack 2 is fixedly connected to the guide rail 23, the pulling rack 443 is fixedly connected to the pulling slider 4431, and the pulling slider 4431 is slidably connected to the guide rail 23 to achieve a sliding connection between the pulling rack 443 and the rack 2.

[0052] In this embodiment, the mounting plate 32 is fixedly connected to a top plate 321, to which a positioning rail 322 is fixedly connected. The positioning rail 322 is located on the side of the top plate 321 near the bowl outlet. The horizontal positioning block 42 is fixedly connected to a positioning slider 422. The positioning slider 422 slides on the positioning rail 322, thereby enabling the horizontal positioning block 42 to slide. The top plate 321 is also fixedly connected to a limiting rail 323. The limiting rail 323 is located on the side of the top plate 321 near the bowl inlet 11. The horizontal limiting block 43 is fixedly connected to a limiting slider 431. The limiting slider 431 is slidably connected to the limiting rail 323, thereby enabling the horizontal limiting block 43 to slide.

[0053] Furthermore, the elastic driving member includes a first nitrogen buffer rod 445 and a second nitrogen buffer rod 446. The top plate 321 has a first abutment portion 3211. The first nitrogen buffer rod 445 is fixedly mounted on the horizontal positioning block 42, and its piston rod is fixedly connected to the first abutment portion 3211. When the pulling rack 443 drives the horizontal positioning block 42 to move away from the flipping station, the piston rod of the first nitrogen buffer rod 445 is compressed. When the limit motor 441 drives the pulling rack 443 to slide toward the flipping station, the hook 444 separates from the hook portion 4211. At this time, the connecting plate 421 is released from the hooking effect of the pulling rack 443, and the piston rod of the first nitrogen buffer rod 445 extends to drive the horizontal positioning block 42 to move toward the flipping station until the hook 444 is hooked on the hook portion 4211 again. The top plate 321 also has a second abutment portion 3212. A second nitrogen buffer rod 446 is fixedly mounted on the horizontal stop block 43, and its piston rod is fixedly connected to the second abutment portion 3212. When the pull rack 443 drives the horizontal positioning block 42 away from the flipping station, the piston rod of the second nitrogen buffer rod 446 is compressed. When the connecting plate 421 is freed from the hook of the pull rack 443, the second nitrogen buffer rod 446 drives the horizontal stop block 43 toward the flipping station.

[0054] Since the buffer rod force of the nitrogen buffer rod is constant, the driving of the horizontal limit plate and the horizontal limit block 43 is achieved by setting the nitrogen buffer rod, which can ensure the smooth sliding of the horizontal limit plate and the horizontal limit block 43 without affecting the torque output of the limit motor 441.

[0055] Reference Figures 5 to 7The positioning and limiting process of the sagger 6 is as follows: the sagger 6 enters the flipping station from the bowl inlet 11 and drives the limiting motor 441 to rotate and drive the rack 443 to move a certain distance toward the flipping station. At this time, the piston rod of the elastic driving member partially extends to drive the horizontal positioning block 42 and the horizontal limiting block 43 to move a certain distance toward the flipping station. When the horizontal positioning block 42 partially extends into the roller table and the horizontal limiting block 43 has not yet extended into the roller table (state 2), the limiting motor 441 is stopped; the horizontal positioning block 42 positions the sagger 6. When the sagger When the sagger 6 moves to abut against the horizontal positioning block 42, the sagger 6 just enters the flipping station, and the height limit block 41 limits the height direction of the sagger 6; at this time, the limit motor 441 is started again to make the pulling rack 443 move further toward the flipping station. While the pulling rack 443 moves toward the flipping station, the elastic driving member drives the horizontal positioning block 42 and the horizontal limit block 43 to move synchronously until the four corners of the sagger 6 are simultaneously restricted by the horizontal positioning block 42 and the horizontal limit block 43 (state 1). At this time, the flipping and unloading action of the sagger 6 can be performed. When the flipping and unloading action is completed, the limit motor 441 is started to drive the pulling rack 443 to pull the connecting plate 421 in the direction away from the flipping station, driving the horizontal positioning block 42 and the horizontal limit block 43 to completely separate from the sagger 6 (state 3). At this time, the sagger 6 can flow out of the closed shell 1 along with the roller shaft 31 and the docking roller.

[0056] A horizontal positioning block 42 is provided to position the sagger 6, and a horizontal limit block 43 is provided to limit the sagger 6 in cooperation with the horizontal positioning block 42. The positioning of the sagger 6 is achieved by mechanical positioning. Compared with sensor positioning, the positioning is more accurate and reliable, and the overall structure is simpler.

[0057] Reference Figures 1 to 4 The mechanical turning and unloading equipment is also provided with a docking roller group 22, a material extraction pipe 211, and a fan filter 12. The two docking roller groups 22 are symmetrically arranged on the side of the turning mechanism 3 near the bowl outlet and the side near the bowl inlet 11. The docking roller group 22 is used to dock with the previous production line to guide the sagger 6 from the bowl inlet 11 to the turning station, or dock with the next production line to guide the sagger 6 from the turning station to the bowl outlet. The material extraction pipe 211 is connected to the hopper 21 and extends to the outside of the closed shell 1. The material extraction pipe 211 is used to connect to the external extraction equipment to extract the material in the hopper 21. The fan filter 12 is set at the top of the closed shell 1 to inject positive pressure into the closed shell 1 in real time. Since the material is prone to dust during the dumping process, the positive pressure is introduced into the closed shell 1 to suppress the dust inside the closed shell 1, allowing each mechanical component to operate in an environment with less dust, which can effectively ensure the service life of each mechanical component. A positive pressure instrument is also provided on the closed shell 1 to monitor the pressure inside the closed shell 1 in real time.
