Description

Technical Field

[0001] The utility model relates to the technical field of battery material mixers, and particularly relates to a high-speed battery material mixer based on centrifugal regulation. Background Technique

[0002] The main constituent materials of a battery include a positive electrode material, a negative electrode material, an electrolyte, and a separator. The selection of each material has an important impact on the performance, safety, and cost of the battery. A battery material mixer is a device or system used to prepare the materials required for battery components. It is usually used to mix various raw materials and chemical substances to form the mixtures required for parts such as the positive electrode, negative electrode, and electrolyte.

[0003] Chinese Patent Publication No. CN220443610U discloses a "lithium battery negative electrode material mixer", which includes a support frame and a conical mixing cylinder installed on the support frame. The upper end of the conical mixing cylinder is detachably connected with a cylinder cover, and the lower end is fixedly connected with a discharge valve. A rotating rod is rotatably connected between the inner walls at both ends of the conical mixing cylinder. A stirring mechanism is arranged on the outer side of the rotating rod, and an anti-blocking mechanism is linked at one end of the stirring mechanism close to the discharge valve. The anti-blocking mechanism includes a spiral blade and an L-shaped stirring rod. This patent drives the stirring mechanism to rotate through the rotation of the rotating rod to stir and mix the materials. When the rotating rod rotates, it drives the spiral blade to rotate synchronously, thereby providing a downward movement force for the mixed lithium battery negative electrode material, accelerating the flow rate of the mixed materials, thereby increasing the outflow rate of the mixed materials, and continuously scraping the discharge port of the conical mixing cylinder through the L-shaped stirring rod linked with the stirring mechanism, thereby preventing foreign objects from blocking the discharge port of the conical mixing cylinder.

[0004] During the conception process, the applicant retrieved a large number of patent documents on the patent network. For example, Chinese Patent Publication No. CN220443610U discloses a "lithium battery negative electrode material mixer". During the stirring process, since the battery material contacts the air while being stirred, some air is incorporated into the battery material, resulting in the appearance of tiny bubbles in the battery material, which affects the quality of the battery material. Therefore, a high-speed battery material mixer based on centrifugal regulation is proposed to solve the above-mentioned problems. Content of the Utility Model

To achieve the above objectives, the present utility model is realized through the following technical solutions: A high-speed battery material mixer based on centrifugal regulation includes a tank body, and a stirring assembly is arranged inside the tank body. The stirring assembly includes a motor, the motor is installed on the tank body, the output end of the motor is connected to a rotating shaft, the bottom of the rotating shaft is connected to a turntable, four small gears are rotatably installed on the turntable, an outer cylinder is connected to the small gears, an inner cylinder is arranged inside the outer cylinder, four large gears are rotatably installed on the turntable, and a toothed ring is installed on the inner wall of the tank body.

[0013] (1) By setting up the stirring assembly, the four inner cylinders can rotate around a common center and rotate on their own axes simultaneously. The centrifugal force generated by the revolution and the centrifugal force generated by the rotation enable the battery materials inside the inner cylinders to be fully and evenly mixed. During the mixing process, due to the effect of the centrifugal force, the tiny bubbles contained in the battery materials move in the direction of the centrifugal force, thus separating from the battery materials, achieving the effect of removing bubbles, and improving the quality of the battery materials.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1-4 As shown, a high-speed battery material mixer based on centrifugal regulation includes a tank body 1. A stirring assembly 4 is arranged inside the tank body 1. The stirring assembly 4 includes a motor 41. The motor 41 is installed on the tank body 1. The output end of the motor 41 is connected to a rotating shaft 42. The bottom of the rotating shaft 42 is connected to a turntable 43. Four small gears 44 are rotatably installed on the turntable 43. An outer cylinder 45 is connected to the small gears 44. An inner cylinder 46 is arranged inside the outer cylinder 45. Four large gears 47 are rotatably installed on the turntable 43. A toothed ring 48 is installed on the inner wall of the tank body 1. The four small gears 44 are arranged in a circular shaft array. The four large gears 47 are respectively meshed with the four small gears 44. The four large gears 47 are all meshed with the toothed ring 48. When the motor 41 is started, the motor 41 drives the turntable 43 to rotate through the rotating shaft 42. The turntable 43 drives the four small gears 44 to revolve. The four small gears 44 drive the four outer cylinders 45 to revolve. While the turntable 43 rotates, it drives the four large gears 47 to revolve. While the four large gears 47 revolve, they rotate by the drive of the toothed ring 48. The four large gears 47 drive the four small gears 44 to rotate. The four small gears 44 drive the four outer cylinders 45 to rotate. A plurality of mounting strips are arranged on the inner wall of the outer cylinder 45. A plurality of mounting grooves are arranged on the outer wall of the inner cylinder 46. The plurality of mounting grooves of the inner cylinder 46 are respectively slidably connected with the mounting strips of the outer cylinder 45. The inner cylinder 46 can be taken out of the outer cylinder 45. After the staff takes out the inner cylinder 46, the battery materials to be stirred and mixed are proportioned and then put into the inner cylinder 46. The staff needs to ensure that the weights of the battery raw materials put into the four inner cylinders 46 are equal. The inner cylinder 46 containing the battery raw materials is put back into the outer cylinder 45. The mounting grooves of the inner cylinder 46 and the mounting strips of the outer cylinder 45 play a limiting role, enabling the inner cylinder 46 to rotate with the outer cylinder 45, so that the four inner cylinders 46 can rotate while revolving. The battery raw materials in the inner cylinder 46 are mixed due to the influence of the revolution centrifugal force and the rotation centrifugal force, and the bubbles in the mixture will be discharged due to the influence of the centrifugal force. Four support plates 2 are hinged to the outer wall of the tank body 1. A shock-absorbing rod 3 is hinged to the support plate 2. The four shock-absorbing rods 3 are all hinged to the outer wall of the tank body 1. During the stirring process, the tank body 1 will generate a certain vibration, and the four support plates 2 and the four shock-absorbing rods 3 can play a certain shock-absorbing role.

[0026] In this embodiment, through the setting of the stirring assembly 4, the four inner cylinders 46 can rotate around a common center and rotate on their own axes simultaneously. The centrifugal force generated by the revolution and the centrifugal force generated by the rotation enable the battery materials inside the inner cylinder 46 to be fully and evenly mixed. During the mixing process, due to the action of the centrifugal force, the small bubbles contained in the battery materials move in the direction of the centrifugal force, thereby separating from the battery materials, achieving the effect of removing bubbles, and thus improving the quality of the battery materials. Through the cooperation of the support plate 2 and the shock-absorbing rod 3, a certain shock-absorbing effect can be achieved, avoiding large vibrations and excessive noise generated by the tank body 1 during the stirring process.

[0027] Embodiment 2

[0028] Please refer to Figures 5-6 As shown, a cooling assembly 5 is provided inside the tank body 1. The cooling assembly 5 includes a hollow shaft 51. The hollow shaft 51 is installed at the bottom of the turntable 43. A condensation box 52 is installed inside the tank body 1. The hollow shaft 51 is rotatably connected to the inner wall of the condensation box 52. A guide plate 54 is installed inside the turntable 43. An inner pipe 55 is installed on the guide plate 54. The inner pipe 55 is located inside the hollow shaft 51. A condensation mesh 56 is installed inside the condensation box 52. An impeller 53 is installed on the inner wall of the hollow shaft 51. When the turntable 43 rotates, the turntable 43 drives the hollow shaft 51, the guide plate 54, and the inner pipe 55 to rotate synchronously. When the hollow shaft 51 rotates, it drives the impeller 53 to rotate. When the impeller 53 rotates, it pumps the coolant in the condensation box 52 into the hollow shaft 51. The hollow shaft 51 transports the coolant to the turntable 43. The coolant in the turntable 43 flows along the guide plate 54 into the inner pipe 55. The coolant in the inner pipe 55 flows into the bottom of the condensation box 52. Since the coolant circulates, the coolant at the bottom of the condensation box 52 will flow upward. During the upward flow of the condensate, it is cooled by contacting the condensation mesh 56, achieving the effect that the condensate can cool the turntable 43 by circulating. The turntable 43 cools the inside of the tank body 1 through heat exchange.

[0029] In this embodiment, through the setting of the cooling assembly 5, the turntable 43 maintains its own temperature through the coolant circulating in the hollow shaft 51, the guide plate 54, the inner pipe 55, and the condensation box 52. The turntable 43 absorbs the heat inside the tank body 1 through heat exchange, achieving the cooling effect, enabling the inside of the tank body 1 to maintain an appropriate temperature, and avoiding the temperature inside the tank body 1 rising after long-term use. Some battery materials may decompose or undergo irreversible chemical changes at high temperatures, resulting in a reduction in material performance and thus affecting product quality.

[0030] When a high-speed battery material mixer based on centrifugal regulation of the present utility model is in use, the inner cylinder 46 can be taken out from the outer cylinder 45. After the staff takes out the inner cylinder 46, the battery materials to be stirred and mixed are proportioned and then put into the inner cylinder 46. The staff needs to ensure that the weights of the battery raw materials put into the four inner cylinders 46 are equal. Then, the inner cylinder 46 filled with the battery raw materials is put back into the outer cylinder 45, and the motor 41 is started. The motor 41 drives the turntable 43 to rotate through the rotating shaft 42. The turntable 43 drives the four small gears 44 to revolve. The four small gears 44 drive the four outer cylinders 45 to revolve. While the turntable 43 is rotating, it drives the four large gears 47 to revolve. While the four large gears 47 are revolving, they rotate by the drive of the toothed ring 48. The four large gears 47 drive the four small gears 44 to rotate. The four small gears 44 drive the four outer cylinders 45 to rotate. Since the installation grooves of the inner cylinder 46 and the installation strips of the outer cylinder 45 play a limiting role, the inner cylinder 46 can rotate following the outer cylinder 45, so that the four inner cylinders 46 can rotate while revolving. The battery raw materials in the inner cylinder 46 are mixed due to the influence of the centrifugal force of revolution and the centrifugal force of rotation, and the bubbles in the mixture will be discharged under the influence of the centrifugal force. During the stirring process, the tank body 1 will generate a certain vibration, and the four support plates 2 and the four shock-absorbing rods 3 can play a certain shock-absorbing role; through the setting of the stirring assembly 4, the four inner cylinders 46 can revolve and rotate simultaneously. The centrifugal force generated by revolution and the centrifugal force generated by rotation enable the battery materials inside the inner cylinder 46 to be fully and evenly mixed. And during the mixing process, due to the action of the centrifugal force, the fine bubbles contained in the battery materials move in the direction of the centrifugal force, so as to separate from the battery materials, achieving the effect of removing bubbles, thereby improving the quality of the battery materials; through the cooperation of the support plates 2 and the shock-absorbing rods 3, a certain shock-absorbing effect can be achieved, avoiding the generation of excessive noise due to the large vibration of the tank body 1 during the stirring process.

[0031] When the turntable 43 rotates, the turntable 43 drives the hollow shaft 51, the flow guide plate 54 and the inner tube 55 to rotate synchronously. When the hollow shaft 51 rotates, it drives the impeller 53 to rotate. When the impeller 53 rotates, it pumps the coolant in the condensation box 52 into the hollow shaft 51. The hollow shaft 51 transports the coolant into the turntable 43. The coolant in the turntable 43 flows into the inner tube 55 along the flow guide plate 54. The coolant in the inner tube 55 flows into the bottom of the condensation box 52. Since the coolant circulates, the coolant at the bottom of the condensation box 52 will flow upward. During the upward flow of the condensate, it is cooled by contacting the condensation net 56, achieving the effect that the condensate can cool the turntable 43 by circulating. The turntable 43 cools the inside of the tank body 1 through heat exchange; through the setting of the cooling component 5, the turntable 43 maintains its own temperature through the coolant circulating in the hollow shaft 51, the flow guide plate 54, the inner tube 55 and the condensation box 52. The turntable 43 absorbs the heat in the tank body 1 through heat exchange, achieving the cooling effect, enabling the inside of the tank body 1 to maintain an appropriate temperature, and avoiding the temperature rise inside the tank body 1 after long-term use. Some battery materials may decompose or undergo irreversible chemical changes at high temperatures, resulting in a reduction in material performance and thus affecting product quality.
