Description

Technical Field

[0001] The utility model belongs to the technical field related to the sintering of high-nickel positive electrode materials, and particularly relates to a sintering device for high-nickel positive electrode materials. Background Art

[0002] With the scarcity of resources caused by the over-exploitation of non-renewable energy sources such as coal and oil, and the huge pollution caused by the use of these resources to our living environment, people are gradually paying attention to new energy sources with sustainable development and environmental friendliness. Electric energy is a widely used clean energy. With the development of urbanization, people's requirements for the environmental friendliness of transportation tools will become higher and higher, and environmentally friendly new energy vehicles such as electric vehicles will become the first choice for people to travel. Lithium-ion batteries have gradually attracted widespread attention due to their advantages such as low cost, environmental protection, low toxicity, no memory effect and high energy density. High-nickel ternary materials used in lithium-ion batteries are the preferred positive electrode materials for current and future automotive power batteries due to their low cost, high energy density, high reversible capacity and environmental friendliness. When processing high-nickel positive electrode materials, corresponding sintering devices are required.

[0003] However, when the existing sintering device is in use, it is not possible to quickly place or remove the high-nickel material on or from the bearing structure because it does not have the function of pulling the bearing structure used in the sintering device, which increases the strength of the staff and reduces the sintering efficiency. At the same time, when the bearing structure is pulled, friction will be generated between the bearing structure and the inner wall of the furnace body, and it is easy to cause the high-nickel material to fall off the bearing structure, resulting in structural damage or material waste. To this end, we provide a sintering device for high-nickel positive electrode materials to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a sintering device for high-nickel positive electrode materials, which limits the material on the upper end of the carrier plate through the coordinated use of a positioning strip plate and a roller drum, and improves the sliding efficiency of the carrier plate and the sealing plate inside the sintering furnace. At the same time, the tooth plate drives the rotation of the rack, so as to facilitate the pulling of the carrier plate and the sealing plate and improve the efficiency of taking and placing materials.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model relates to a sintering device for a high-nickel cathode material, which comprises a sintering furnace, a heater fixed on the peripheral side of the upper part of the sintering furnace, an exhaust fan communicated with the right end of the sintering furnace, and an oxygen delivery rack communicated with the inside of the sintering furnace; a sealing plate is arranged at the left end of the sintering furnace, a bearing plate is fixed at the middle position of the right end face of the sealing plate, positioning strip plates are fixed on the right end face of the sealing plate in front and behind the bearing plate, a plurality of rotation openings are linearly and uniformly arranged on the side walls of the positioning strip plates, roller cylinders connected with the inner side wall of the sintering furnace are rotatably arranged inside the rotation openings, a rack located below the sintering furnace is fixed on the peripheral side of the lower end of the sealing plate, and a motor is arranged at the position below the rack on the left side of the sintering furnace, and a gear plate meshed with the rack is fixed at the rotating shaft end of the motor.

[0007] The utility model is further arranged that shaft rods are fixed between the upper and lower surfaces inside the rotation openings, and the roller cylinders are rotatably sleeved on the peripheral sides of the shaft rods.

[0008] The utility model is further arranged that a bottom plate is arranged directly below the sintering furnace, and L-shaped plates are fixed at the front and rear positions of the left and right parts of the sintering furnace.

[0009] The utility model is further arranged that support plates are fixed on the upper end surfaces of the L-shaped plates, and the upper end surfaces of the support plates are attached to the peripheral side walls of the sintering furnace.

[0010] The utility model is further arranged that the motor, the oxygen delivery rack and the exhaust fan are all fixedly connected to the upper end surface of the bottom plate, the oxygen delivery rack is located behind the sintering furnace, and the exhaust fan is located on the right side of the sintering furnace.

[0011] The utility model is further arranged that the motor, the oxygen delivery rack and the exhaust fan are all fixedly connected to the upper end surface of the bottom plate.

[0012] The utility model is further arranged that a limiting plate is fixed at the lower part of the right end of the rack, and a limiting hole is arranged at the middle position of the side wall of the limiting plate.

[0013] The utility model is further arranged that a baffle is fixed on the upper end surface of the bottom plate directly below the sealing plate, and a limiting rod slidably passing through the inside of the limiting hole is fixed on the right end surface of the baffle.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the present utility model is in use, the motor directly drives the electric rack through the toothed plate to move leftward, and the rack drives the sealing plate to disengage from the left end face of the sintering furnace. Moreover, the sealing plate drives the bearing plate to move out of the interior position of the sintering furnace. Then, the user can place the high-nickel cathode material on the bearing plate and control the motor to reverse. As a result, the sealing plate will be driven to reconnect with the left end face of the sintering furnace and seal it. At this time, the bearing plate has completely moved into the sintering furnace, and thus the high-nickel cathode material can be sintered, thereby facilitating the extraction and insertion of the bearing plate and the sealing plate and improving the material loading and unloading efficiency.

[0016] 2. When the present utility model is in use, when the sealing plate moves, the sealing plate will drive the positioning strip plate to slide inside the sintering furnace. And when the roller cylinder is driven, there will be friction between the roller cylinder and the inner side wall of the sintering furnace. At the same time, the use of the positioning strip plate and the roller cylinder can facilitate the sliding efficiency of the sealing plate and limit the front and rear parts of the bearing plate, thereby ensuring the sliding stability of the sealing plate and the bearing plate.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Specific embodiment 1

[0028] Please refer to Figures 1-5 , the present invention is a sintering device for high-nickel cathode materials. By the cooperation between the positioning strip plate 402 and the roller cylinder 403, the materials on the upper end of the bearing plate 401 are limited, and the sliding efficiency of the bearing plate 401 and the sealing plate 4 inside the sintering furnace 1 is improved. At the same time, the rotation of the tooth plate 501 drives the rack 406, so as to facilitate the extraction of the bearing plate 401 and the sealing plate 4 and improve the material loading and unloading efficiency.

[0029] Specifically, a sintering furnace 1, a heater 2 fixed on the peripheral side of the upper part of the sintering furnace 1, an exhaust fan connected to the right end of the sintering furnace 1, and an oxygen delivery rack 3 connected to the inside of the sintering furnace 1; a sealing plate 4 is arranged at the left end of the sintering furnace 1, a bearing plate 401 is fixed at the middle position of the right end face of the sealing plate 4, positioning strip plates 402 are fixed on the right end faces of the sealing plate 4 in front and behind the bearing plate 401, a plurality of rotating ports 404 arranged linearly are opened on the side walls of the positioning strip plates 402, roller cylinders 403 connected to the inner side wall of the sintering furnace 1 are rotatably arranged inside the rotating ports 404, a rack 406 located below the sintering furnace 1 is fixed on the peripheral side of the lower end of the sealing plate 4, a motor 5 is arranged at the position below the rack 406 on the left side of the sintering furnace 1, a tooth plate 501 meshing with the rack 406 is fixed at the rotating shaft end of the motor 5, a shaft rod 405 is fixed between the upper and lower surfaces inside the rotating port 404, and the roller cylinder 403 is rotatably sleeved on the peripheral side of the shaft rod 405. The motor 5, the oxygen delivery rack 3 and the exhaust fan 7 are all fixedly connected to the upper end face of the bottom plate 6. The oxygen delivery rack 3 is located behind the sintering furnace 1, and the exhaust fan 7 is located on the right side of the sintering furnace 1.

[0030] The operation process of this embodiment is as follows: Through the use of the above structure, when controlling the heater 2, the oxygen delivery rack 3, and the exhaust fan to work, sintering work is carried out inside the sintering furnace 1. Therefore, when processing the high-nickel cathode material, the motor 5 can be controlled to rotate forward. Thus, the motor 5 directly moves the electric rack 406 to the left through the toothed plate 501, and the rack 406 drives the sealing plate 4 to disengage from the left end face of the sintering furnace 1. And the sealing plate 4 drives the bearing plate 401 to move out of the interior position of the sintering furnace 1. Then, the user can place the high-nickel cathode material on the bearing plate 401 and control the motor 5 to rotate in reverse. Therefore, it will drive the sealing plate 4 to reconnect with the left end face of the sintering furnace 1 and seal it. At this time, the entire bearing plate 401 has moved into the sintering furnace 1, and thus the high-nickel cathode material can be sintered. At the same time, when the sealing plate 4 moves, the sealing plate 4 will drive the positioning strip 402 to slide inside the sintering furnace 1. And when the roller cylinder 403 is driven, friction will be generated between the roller cylinder 403 and the inner side wall of the sintering furnace 1. At the same time, the use of the positioning strip 402 and the roller cylinder 403 can facilitate the sliding efficiency of the sealing plate 4 and limit the front and rear parts of the bearing plate 401. Specific Embodiment Two

[0032] Please refer to Figure 5 , on the basis of Specific Embodiment One, through the support of the L-shaped plate 604 for the support plate 601, multiple points on the periphery of the sintering furnace 1 are limited to ensure the stable position of the sintering furnace 1.

[0033] Specifically, a bottom plate 6 is provided directly below the sintering furnace 1. L-shaped plates 604 are fixed at the front and rear positions of the left and right parts of the sintering furnace 1. Support plates 601 are fixed on the upper end surfaces of the L-shaped plates 604, and the upper end surfaces of the support plates 601 are in contact with the peripheral side wall of the sintering furnace 1.

[0034] The operation process of this embodiment is as follows: Through the support treatment of the L-shaped plate 604 for the support plate 601, the support plate 601 is stably connected to the periphery of the sintering furnace 1, so that the support plate 601 supports the sintering furnace 1, and the sintering furnace 1 is stably located on the upper end surface of the bottom plate 6. Specific Embodiment Three

[0036] Please refer to Figure 3 , 4 , 5, on the basis of Specific Embodiment One, by ensuring that the limiting rod 603 is located inside the limiting hole 408, the sealing plate 4 and the bearing plate 401 are prevented from rotating.

[0037] Specifically, a limiting plate 407 is fixed to the lower part of the right end of the rack 406. Limiting holes 408 are formed in the middle positions of the side walls of the limiting plate 407. A baffle 602 is fixed to the upper end surface of the bottom plate 6 directly below the sealing plate 4. A limiting rod 603 that slidably passes through the inner position of the limiting hole 408 is fixed to the right end surface of the baffle 602.

[0038] The operation process of this embodiment is as follows: When the rack 406 is driven by the toothed plate 501, the rack 406 will drive the limiting plate 407 to slide on the upper end surface of the bottom plate 6, and the limiting plate 407 will slide along the limiting rod 603 through the limiting hole 408. At the same time, the baffle 602 will limit the limiting plate 407, restricting the movement range of the limiting plate 407, so that the bearing plate 401 is limited, ensuring that the bearing plate 401 will not completely come out of the sintering furnace 1. And the limiting rod 603 is located inside the limiting hole 408, thereby ensuring that the sealing plate 4 and the bearing plate 401 will not rotate.
