Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell furnace technology, and in particular to a high-efficiency graphitization intelligent integrated electrolytic cell furnace device. Background Technology

[0002] Against the backdrop of rapid development in the new energy, high-end carbon materials, and advanced composite materials industries, the demand for powdered materials such as lithium battery anode materials, high-end graphite product raw materials, and basic raw materials for the carbon industry continues to rise. High-temperature graphitization of these materials has become a core step in improving their performance. High-efficiency graphitization intelligent furnace integrated electrolytic cell devices, due to their combined functions of high-temperature graphitization and electrolytic refining, and their ability to achieve precise temperature control and automated traceability of process parameters through an intelligent control system, have become key equipment for the deep processing of powdered carbonaceous materials. They are widely used in the mass production of lithium battery anode materials, the preparation of special graphites, and the processing of carbon electrodes for metal smelting. However, existing graphitization intelligent furnace integrated electrolytic cell devices often employ a traditional vertical hopper gravity feeding design, which is prone to overfeeding. When overfeeding occurs, the material accumulates too thickly inside the furnace, leading to uneven local temperature conduction, incomplete graphitization reaction, and severely affecting the performance of the finished product. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing graphitization intelligent furnace integrated electrolytic cell furnace device mainly adopts the traditional design of vertical hopper with gravity feeding, which is prone to overfeeding. Therefore, we propose a high-efficiency graphitization intelligent furnace integrated electrolytic cell furnace device.

[0004] To achieve the above objectives, this application adopts the following technical solution: A high-efficiency graphitization intelligent integrated electrolytic cell furnace device, comprising an electrolytic cell furnace body and a control panel installed on the outer wall of the electrolytic cell furnace body. An installation block is provided on one side of the electrolytic cell furnace body, and a feed pipe is installed on the inner wall of the installation block. One end of the feed pipe leads to the inner cavity of the electrolytic cell furnace body, and the end of the feed pipe away from the electrolytic cell furnace body is connected to a feed hopper. A motor is installed on the outer wall of the feed hopper, and a rotating rod body is fixedly connected to the output end of the motor. The rotating rod body is rotatably connected to the inner wall of the feed hopper, and a dispersing roller is fixedly connected to the outer wall of the rotating rod body. A partition body is axially connected to the inner wall of the feed hopper.

[0005] Furthermore, the partition body is located at the lower end of the rotating rod body, and the outer wall of the dispersing roller is fixedly connected to the top rod body, which is used to push open the partition body for material feeding. Through the synchronous rotation of the top rod body and the dispersing roller, intermittent opening and feeding is achieved, replacing the traditional gravity continuous feeding mode.

[0006] Furthermore, a rotating shaft assembly is installed at one end of the connecting shaft of the partition body. The rotating shaft assembly provides stable support for the rotation of the partition body, ensuring that the partition always rotates around a fixed axis during the pushing and resetting process of the top rod body.

[0007] Furthermore, the rotating shaft assembly includes an inner shaft body fixedly connected to a connecting shaft at one end, and an outer shaft body fixedly connected to the inner wall of the feed hopper, wherein the outer shaft body is sleeved on the outer wall of the inner shaft body.

[0008] Furthermore, a reset torsion spring is fixedly connected to the inner wall of the outer shaft body, and a central connecting rod is fixedly connected to one end of the reset torsion spring. The end of the central connecting rod away from the reset torsion spring is fixedly connected to the inner shaft body. Automatic reset of the partition body can be achieved without additional power, simplifying the control process and reducing energy consumption. The elasticity of the reset torsion spring is stable and durable, ensuring that the partition can quickly and tightly reset and seal after each push rod is removed.

[0009] Furthermore, in the relaxed state of the reset torsion spring, the partition body is sealed in the inner cavity of the feed hopper. This state is the initial standby state of the device. At this time, the partition body completely blocks the connection between the feed hopper and the feed pipe, and the material cannot fall by itself. It only opens to discharge when the push rod body actively pushes.

[0010] The technical effects and advantages of this utility model are as follows: In this invention, the motor-driven rotating rod body on the outer wall of the feed hopper drives the dispersing roller to rotate. The dispersing roller not only disperses the lumpy material in the hopper, but its outer wall push rod body also intermittently pushes the partition body connected to the lower shaft as it rotates. The material only enters the furnace intermittently through the feed pipe under the action of the push rod body. The opening and closing frequency and duration of the partition body are controlled by the motor speed to achieve precise control of the feed amount, avoiding excessive feeding from affecting the stability of the reaction in the furnace. This solves the problem that the feed structure of the existing graphitization intelligent furnace integrated electrolytic cell furnace device mostly adopts the traditional design of vertical hopper with gravity feeding, which is prone to the problem of excessive feeding.

[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0014] Reference Figures 1-4 As shown, in order to solve the problem that the traditional design of vertical hopper gravity feeding in existing graphitization intelligent furnace integrated electrolytic cell devices is prone to overfeeding, the following preferred technical solution is provided: An efficient graphitization intelligent integrated electrolytic cell furnace device includes an electrolytic cell furnace body 1 and a control panel 2 installed on the outer wall of the electrolytic cell furnace body 1. The device uses the electrolytic cell furnace body 1 as the core reaction carrier. The control panel 2 installed on its outer wall is used to regulate parameters such as furnace temperature and feeding frequency to achieve intelligent control. An installation block 3 on one side of the electrolytic cell furnace body 1 provides fixed support for the feed pipe 4. One end of the feed pipe 4 leads to the inner cavity of the electrolytic cell furnace body 1 and is responsible for conveying materials into the furnace. The other end is connected to the feed hopper 5. The feed hopper 5 serves as a material temporary storage container to receive the graphite raw materials. An electric motor 6 installed on the outer wall of the feed hopper 5 provides power for feeding control. The output end of the motor is fixedly connected to the rotating rod body 7, which is rotatably connected to the inner wall of the feed hopper 5 through bearings. The dispersing roller 8 fixed on the outer wall of the rotating rod body 7 rotates synchronously with the rotating rod to pre-treat the materials. The partition body 9, which is axially connected to the inner wall of the feed hopper 5, serves as a discharge switch to control whether the materials enter the feed pipe 4. The partition body 9 is located at the lower end of the rotating rod body 7. The outer wall of the dispersing roller 8 is fixedly connected to the push rod body 10, which is used to push open the partition body 9 for material feeding. When the motor 6 drives the rotating rod body 7 to rotate, the dispersing roller 8 rotates synchronously, and the push rod body 10 on its outer wall moves in a circular motion with the dispersing roller. When the push rod body 10 rotates to contact the partition body 9, it will push the partition body 9 outward, causing the partition to rotate around the connecting shaft and open the feeding channel. When the push rod body 10 rotates away from the partition body 9 with the dispersing roller, the partition body 9 closes the channel under the action of the reset structure. The intermittent opening and feeding is achieved by the synchronous rotation of the push rod body 10 and the dispersing roller 8, replacing the traditional gravity continuous feeding mode. The frequency and duration of the partition opening can be precisely controlled according to the speed of the motor 6, thereby controlling the amount of material fed at one time and fundamentally avoiding overfeeding. At the same time, when the dispersing roller 8 rotates, it can break up the lumps of graphite raw materials in the feed hopper 5, preventing the lumps of material from blocking the feed channel, ensuring smooth feeding, and avoiding uneven feeding or sudden overfeeding caused by blockage. A rotating shaft assembly 11 is installed at one end of the connecting shaft of the partition body 9. The rotating shaft assembly 11 provides stable support for the rotation of the partition body 9, ensuring that the partition always rotates around a fixed axis during the pushing and resetting process of the push rod body 10, avoiding poor sealing or jamming of the partition due to axis misalignment. This improves the rotational stability of the partition body 9, prevents material leakage caused by partition misalignment, ensures the reliability of feed control, and avoids overfeeding problems caused by material leakage. The rotating shaft assembly 11 includes an inner shaft body 111 fixedly connected to a connecting shaft at one end, and an outer shaft body 112 fixedly connected to the inner wall of the feed hopper 5. The outer shaft body 112 is sleeved on the outer wall of the inner shaft body 111. The inner shaft body 111 rotates synchronously with the connecting shaft of the partition body 9, while the outer shaft body 112 remains stationary. This nested structure provides stable rotation guidance for the inner shaft and encapsulates the reset structure between the inner and outer shafts, preventing material dust from entering the rotating shaft and affecting rotation. It also makes the overall structure more compact and saves space inside the feed hopper 5. This ensures that the inner shaft body 111 rotates without deviation, guaranteeing the sealing accuracy of the partition body 9. The encapsulated structure reduces dust wear on the rotating shaft assembly, extends its service life, prevents partition malfunction due to rotating shaft failure, and further prevents overfeeding. A reset torsion spring 113 is fixedly connected to the inner wall of the outer shaft body 112. One end of the reset torsion spring 113 is fixedly connected to a central connecting rod 114, and the end of the central connecting rod 114 away from the reset torsion spring 113 is fixedly connected to the inner shaft body 111. When the push rod body 10 pushes the partition body 9, the partition drives the connecting shaft and the inner shaft body 111 to rotate. The inner shaft twists the reset torsion spring 113 through the central connecting rod 114, causing the torsion spring to store force. When the push rod body 10 rotates away from the partition, the reset torsion spring 113 releases the stored force, and pulls the inner shaft body 111 to rotate in the opposite direction through the central connecting rod 114, causing the partition body 9 to reset. Automatic reset of the partition body 9 can be achieved without additional power, simplifying the control process and reducing energy consumption. The elasticity of the reset torsion spring 113 is stable and durable, ensuring that the partition can quickly and tightly reset and seal after each push rod leaves, avoiding continuous material falling due to reset delay, further controlling the feed rate and preventing overfeeding.

[0015] With the reset torsion spring 113 relaxed, the baffle body 9 is sealed within the inner cavity of the feed hopper 5. This is the initial standby state of the device. At this time, the baffle body 9 completely blocks the connection between the feed hopper 5 and the feed pipe 4, preventing material from falling on its own. The material is only released when the push rod body 10 actively pushes, thus eliminating the problem of excessive material flow caused by natural slippage in traditional gravity feeding. This ensures zero material leakage during non-feeding stages, preventing material from accidentally falling into the furnace when the equipment is idle or being adjusted, ensuring accurate initial material quantity in the furnace. It also allows operators to adjust the motor 6 speed via the control panel 2 according to production needs, controlling the feeding rhythm as required, and improving feeding flexibility and accuracy.

[0016] Specifically, with the electrolytic cell furnace body 1 as the core reaction carrier, the operator sets the feeding parameters through the control panel 2 on the outer wall. The feeding pipe 4, supported by the mounting block 3 on one side of the electrolytic cell furnace body 1, connects the feeding hopper 5, which temporarily stores graphite raw materials, to the furnace. The motor 6 on the outer wall of the feeding hopper 5 drives the rotating rod body 7 to rotate the dispersing roller 8. The dispersing roller 8 disperses the lumpy material in the hopper, and its outer wall push rod body 10 intermittently pushes the partition body 9 connected to the lower shaft as it rotates. The partition body 9 is connected to the rotating shaft assembly 11 at one end of the shaft. The inner shaft body 111 and the outer shaft body 112 are nested. The return torsion spring 113 on the inner wall of the outer shaft body 112 is connected to the inner shaft body 111 via the intermediate connecting rod 114. When the push rod is pushed, the inner shaft body 111 drives the reset torsion spring 113 to store force, and the partition body 9 opens to discharge material. After the push rod body 10 rotates away, the reset torsion spring 113 resets and drives the partition body 9 to seal the feed hopper 5. When the reset torsion spring 113 relaxes, the partition always seals the hopper cavity. The material only enters the furnace intermittently through the feed pipe 4 under the action of the push rod body 10. The opening and closing frequency and duration of the partition body 9 are adjusted by the speed of the motor 6 to achieve precise control of the feed amount and avoid excessive feeding from affecting the stability of the reaction in the furnace. This solves the problem that the feeding structure of the existing graphitization intelligent furnace integrated electrolytic cell furnace device mostly adopts the traditional design of vertical hopper and gravity feeding, which is prone to excessive feeding.

[0017] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
