Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and more specifically, to a double-chamber material suction device for the negative electrode material of a lithium battery. Background Art

[0002] Lithium batteries are a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. With the development of science and technology, lithium batteries have become the mainstream. Graphitization, as one of the important links in the production of lithium batteries, uses electric heating to graphitize coke powder at about 3000 degrees to become graphite powder. While producing the graphite negative electrode material, a by-product recarburizer is also generated. During charging and discharging, a double-beam overhead crane and a material suction overhead crane are used, and the screening of the recarburizer with the negative electrode powder filling box is also equipped with automated equipment to achieve automated production, which can reduce labor intensity and reduce the number of personnel. However, when the existing device sucks materials during the processing of the graphite negative electrode material, the discharge pipe extends through the distribution plate and the orientation plate, and the orientation plate is close to the distribution plate, so that the orientation plate and the distribution plate form a material guiding end to guide the negative electrode material discharged from the discharge pipe to both sides, realizing multi-position feeding of the negative electrode material. However, each time material is sucked, an operator needs to hold the discharge pipe by hand and insert it into the negative electrode material barrel for feeding. Due to the high requirements for the material suction processing of the lithium battery negative electrode material, the discharge pipe is cumbersome to use, consumes the physical energy of the user, and is not conducive to industrial automated production, resulting in low production efficiency.

[0003] Regarding the above problems, in terms of the technical problems that the discharge pipe is cumbersome to use, consumes the physical energy of the user, is not conducive to industrial automated production, and results in low production efficiency, after a large number of searches, a double-chamber material suction device for the negative electrode material of a lithium battery with the patent application number 202323018187.1 was found, belonging to the field of lithium batteries, including a double-chamber feeder, a base, and a material suction mechanism. The double-chamber feeder is fixedly installed on the base, and a material suction mechanism is arranged beside the double-chamber feeder on the base. With the function of the blower set in this utility model, the lithium battery negative electrode material is sucked from the feeding hopper, and through the guidance of the stainless steel material pipe and the hose, the lithium battery negative electrode material is sucked and automatically sucked into the double-chamber feeder for processing, realizing the convenience of using the material suction device, reducing the trouble of manually holding the device for material suction, and realizing the automation of the lithium battery negative electrode material suction. However, the technical solution provided by this patent has the following problems:

[0004] When feeding materials, it is necessary to connect the connecting block to the pipeline and then feed the materials in the silo. When feeding another cavity, it is necessary to disconnect the connecting block from the pipeline and then pull the handle to move the chassis to another place to feed the materials. This feeding method is prone to wasting time and having low feeding efficiency. When feeding one cavity, the other cavity is in a waiting state and cannot feed materials simultaneously, resulting in a slower production rhythm. Moreover, each time of switching requires operations such as reconnecting and moving the chassis again, which makes there be interruptions in the feeding process and unable to maintain a stable feeding speed. The discontinuity of feeding may also cause unstable flow of materials in the pipeline, increasing the risk of blockage and further reducing the feeding efficiency.

[0005] The utility model can achieve alternate or simultaneous feeding of two cavities, greatly improving the feeding speed and efficiency. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the technical problems raised in the above background technology and provide a double - cavity material suction device for lithium - battery negative electrode materials.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: A double - cavity material suction device for lithium - battery negative electrode materials, comprising: a base, on the upper front side of the base, first blowers are fixedly installed on both the left and right sides above, a transfer table is fixedly installed outside each first blower, a second blower is fixedly installed on the rear side of each transfer table, a double - cavity feeder is fixedly installed on the rear side of the upper end of the base, a feed bin is fixedly installed on the front side of the upper end of the base, the first blower is behind the feed bin, a discharge pipe is fixedly installed at the rear end of the feed bin, and distribution pipes are fixedly installed on both the left and right sides at the upper end of the discharge pipe.

[0008] Further preferred scheme: a feed inlet is opened at the upper end of the feed bin, and the distribution pipes are respectively fixedly connected to the first blowers on both the left and right sides behind the feed bin.

[0009] Further preferred scheme: a transfer pipe is fixedly installed inside each first blower, and the transfer pipes are respectively fixedly connected to the distribution pipes.

[0010] Further preferred scheme: a conveying pipe is fixedly installed at the other end of each first blower, the other end of the conveying pipe is fixedly connected to the transfer table, a transfer bin is fixedly installed inside the transfer table, and the conveying pipe is fixedly connected to the upper end of the transfer bin.

[0011] Further preferred scheme: support legs are fixedly installed at the four corners of the bottom of the transfer table, foot pads are fixedly installed at the bottoms of the support legs, conveying pipes are fixedly installed at the rear ends of the transfer bins, and the other ends of the conveying pipes are fixedly connected to the second blowers.

[0012] A further preferred solution: a feed pipe is fixedly installed at the rear end of the second blower, a loading pipe is fixedly installed at the other end of the feed pipe, the loading pipe is inclined upward at 35 degrees, and the other end of the loading pipe is fixedly connected to the double-cavity loading machine.

[0013] Beneficial effects:

[0014] 1. The first blower and the second blower are provided as important power sources of the suction device, which generate strong airflow to promote the transmission of the negative electrode material. The first blower is mainly responsible for sucking the negative electrode material from the feed bin into the transfer table, and the second blower further provides power for the material transportation, ensuring that the negative electrode material can smoothly enter the double-chamber feeder;

[0015] 2. The material transfer table is provided to transfer and distribute materials. The material transfer bin can temporarily store the negative electrode materials transmitted from the first blower to avoid interruption or instability of the materials during the transmission process. At the same time, the material transfer table is connected to the second blower through the material transport pipe to accurately transport the materials to the next link.

[0016] 3. The feeding pipe is set at an upward inclination of 35 degrees. Compared with a completely vertical pipeline, it can save power. The inclination angle allows the material to move upward under the combined action of airflow and gravity, reducing the power consumption of the blower for vertical lifting simply relying on strong wind pressure. The material in a completely vertical pipeline is prone to unstable falling due to gravity, while the inclined feeding pipe allows the material to have a gradual upward process under the push of airflow, reducing the risk of sudden material falling or clogging the pipeline;

[0017] 4. In summary, the dual-chamber suction device for negative electrode materials of lithium batteries is provided with a distribution pipe, a first blower, a rotating material table, a second blower and a feeding pipe and other structures. The distribution pipe can evenly distribute the negative electrode materials coming out of the feed bin to the first blowers on the left and right sides, so as to ensure that when the two blowers work at the same time, they can absorb the materials evenly to avoid the situation where one side is overloaded and the other side is idle. Then the material is transported to the rotating material table through the first blower. The rotating material table plays the role of transferring and storing the negative electrode materials. The material sucked in from the first blower first enters the rotating material table, where it is temporarily stored and buffered. It transfers the material sucked in from the first blower to the second blower, and the airflow it generates pushes the material coming out of the rotating material table to the dual-chamber loader through the feeding pipe.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-3 drawings in the embodiments of the present utility model.

[0023] Please refer to Figures 1-3, in the embodiment of the present utility model, a double-chamber material suction device for the negative electrode material of a lithium battery includes: a base 1, on the upper front side of the base 1, two first blowers 2 are fixedly installed on both the left and right sides above, a transfer table 3 is fixedly installed on the outside of each first blower 2, a second blower 4 is fixedly installed on the rear side of each transfer table 3, a double-chamber feeding machine 5 is fixedly installed on the upper rear side of the base 1, a feeding bin 101 is fixedly installed on the upper front side of the base 1, the first blowers 2 are behind the feeding bin 101, a discharge pipe 103 is fixedly installed at the rear end of the feeding bin 101, two distribution pipes 104 are fixedly installed on both the left and right sides at the upper end of the discharge pipe 103, a feeding port 102 is opened at the upper end of the feeding bin 101, the distribution pipes 104 are respectively fixedly connected to the first blowers 2 on both the left and right sides behind the feeding bin 101, a transfer pipe 201 is fixedly installed on the inner side of each first blower 2, and the transfer pipes 201 are respectively fixedly connected to the distribution pipes 104. The first blowers 2 are located on both the left and right sides above the upper front side of the base 1 and are one of the important power sources in the material suction process. By generating a strong airflow, the negative electrode material is sucked from the feeding bin 101 into the transfer table 3 and subsequent pipes. The transfer table 3 is fixedly installed on the outside of the first blower 2 and functions as a transfer and distribution device for the material, ensuring the smooth flow of the negative electrode material therein and avoiding blockage and accumulation. Then, the material is transferred to the second blower 4 through the transfer table 3, which further provides power for the material transportation and works in cooperation with the first blower 2 to ensure that the negative electrode material can smoothly enter the double-chamber feeding machine 5. During use, first, the negative electrode material is loaded into the feeding bin 101 through the feeding port 102, the discharge pipe 103 transports the material in the feeding bin 101 to the distribution pipes 104, and then the distribution pipes 104 evenly distribute the material to the first blowers 2 on both the left and right sides. The first blowers 2 are started to generate a strong airflow, and the airflow enters the feeding bin 101 through the transfer pipes 201 and the distribution pipes 104, sucking the negative electrode material into the transfer table 3. The material in the transfer table 3 is transported to the second blower 4 under the action of the airflow. The second blower 4 further enhances the airflow and sends the material into the double-chamber feeding machine 5. The double-chamber feeding machine 5 receives the negative electrode material from the second blower 4 and transports it to subsequent production equipment. When it is not necessary to perform feeding and discharging simultaneously, only the first blower 2 and the second blower 4 on one side need to be started, so that the pipeline on one side transfers and feeds the negative electrode material on the feeding bin 101.

[0024] In the embodiment of the present utility model, a material conveying pipe 202 is fixedly installed at the other end of the first blower 2. The other end of the material conveying pipe 202 is fixedly connected to the material transfer table 3. A material transfer bin 301 is fixedly installed inside the material transfer table 3. The material conveying pipe 202 is fixedly connected to the upper end of the material transfer bin 301. A material transporting pipe 304 is fixedly installed at the rear end of the material transfer bin 301. The other end of the material transporting pipe 304 is fixedly connected to the second blower 4. The airflow generated by the first blower 2 conveys the negative electrode material from one side of the feeding bin 101 to the material transfer bin 301 inside the material transfer table 3 through the material conveying pipe 202. The material transfer bin 301 can temporarily store the negative electrode material transmitted from the first blower 2. Then, through the material transporting pipe 304 at the rear end of the material transfer bin 301 and the second blower 4, the material transporting pipe 304 conveys the negative electrode material in the material transfer bin 301 to the second blower 4, and then the second blower 4 conveys the negative electrode material backward.

[0025] In the embodiment of the present utility model, support legs 302 are fixedly installed at the four corners of the bottom of the material transfer table 3. Foot pads 303 are fixedly installed at the bottom of the support legs 302. The support legs 302 are located at the four corners of the bottom of the material transfer table 3, providing stable support for the material transfer table 3. They can bear the weight of the material transfer table 3 and the negative electrode material in the material transfer bin 301 inside it, ensuring that the material transfer table 3 does not shake or tilt during operation. The foot pads 303 are fixedly installed at the bottom of the support legs 302, playing a role in shock absorption and anti-slip. During the operation of the equipment, vibrations and impact forces may be generated. The foot pads 303 can absorb these vibrations and impact forces, reducing the impact on the equipment and the surrounding environment. Moreover, the foot pads 303 can also increase the friction between the support legs 302 and the ground, preventing the material transfer table from sliding during operation.

[0026] In the embodiment of the present utility model, a material feeding pipe 401 is fixedly installed at the rear end of the second blower 4. The other end of the material feeding pipe 401 is fixedly installed with a feeding pipe 402. The feeding pipe 402 is inclined upward at an angle of 35 degrees. The other end of the feeding pipe 402 is fixedly connected to the double-chamber feeding machine 5. When the negative electrode material reaches the material transfer table 3, the second blower 4 further provides power for the transmission of the negative electrode material. The negative electrode material coming out of the material transfer table 3 is continuously conveyed forward under the action of the airflow generated by the second blower 4 through the material feeding pipe 401, then enters the feeding pipe 402 through the material feeding pipe 301, and is transported upward into the double-chamber feeding machine through the feeding pipe 402. Since the feeding pipe 402 is inclined upward at an angle of 35 degrees, during upward transmission, compared with a completely vertical pipe, it saves more power. At the same time, it is more stable and reliable. In a completely vertical pipe, the material is likely to fall unstably due to the action of gravity, while the inclined feeding pipe 402 allows the material to have a gradually rising process under the push of the airflow, reducing the risk of the material suddenly falling or blocking the pipe.

[0027] Working principle: First, the negative electrode material is loaded into the feed bin 101 through the feed inlet 102. The discharge pipe 103 transports the material in the feed bin 101 to the distribution pipe 104. The distribution pipe 104 evenly distributes the material to the first blowers 2 on the left and right sides. The first blowers 2 are started to generate a strong air flow. The air flow enters the feed bin 101 through the transfer pipe 201 and the distribution pipe 104, sucking the negative electrode material into the transfer bin 301 in the transfer table 3. The transfer bin 301 temporarily stores the negative electrode material. In the transfer bin 301, under the action of the air flow, the material is transported to the second blower 4 through the material transportation pipe 304. The second blower 4 further enhances the air flow and transports the negative electrode material backward. The negative electrode material continues to be transported forward through the material delivery pipe 401. The negative electrode material enters the feeding pipe 402 which is inclined upward at 35 degrees through the material delivery pipe 301, and is transported upward from the feeding pipe 402 into the double-chamber feeding machine 5. The double-chamber feeding machine 5 transports the negative electrode material to the subsequent production equipment. When only single-sided feeding or non-simultaneous feeding is required, only the first blower 2 and the second blower 4 on one side need to be started, so that the pipeline on one side transfers and feeds the negative electrode material on the feed bin 101.
