Description

Technical Field

[0001] The invention relates to the technical field of graphite mixers, in particular to a multifunctional graphite mixer. Background Art

[0002] In the field of graphite processing, multifunctional graphite mixer, as a key equipment, plays a vital role in the uniform mixing of graphite raw materials. Its performance directly affects the quality and production efficiency of subsequent graphite products. With the continuous growth of the application demand of graphite materials in high-end fields such as new energy, electronic information, aerospace, etc., more stringent requirements are put forward for the uniformity, efficiency and process adaptability of graphite mixing. At present, there are many kinds of multifunctional graphite mixers on the market, but they generally adopt the more traditional stirring method. Such mixers are usually equipped with a single rotating shaft, on which a stirring blade of a specific shape is installed. During the stirring process, the stirring blade makes a single-direction circular motion around the rotating shaft, relying on the relative movement between the blade and the graphite raw material to generate shear force, friction force and other forces, pushing the raw material to flow in the stirring container, thereby achieving the purpose of mixing. In order to enhance the mixing effect, some equipment will set multiple layers of stirring blades on the stirring shaft. Through the synergistic effect of blades of different heights, the flow of the raw material in the vertical direction is increased, trying to improve the mixing uniformity; The stirring force generated by the existing traditional stirring method is relatively single, mainly concentrated in the circular motion in the horizontal direction, and the stirring range and stirring intensity of the graphite raw material are limited. During the stirring process, it is difficult to achieve full mixing of the graphite raw material in a short time, especially when processing a large amount of raw materials or high-viscosity graphite slurry. The stirring time is significantly extended, resulting in low production efficiency. Moreover, since the motion trajectory of the stirring blade is relatively fixed, there is an obvious stirring dead angle in the stirring container. Some raw materials are in a low-speed flow or static state for a long time and cannot be fully contacted and mixed with the surrounding raw materials, further reducing the overall stirring efficiency; Moreover, during the stirring process, due to the characteristics of the graphite raw materials themselves, such as the density difference of particles of different particle sizes and the uneven viscosity of the raw materials, stratification of the upper and lower layers is very likely to occur. The stirring blades of the traditional mixer are difficult to effectively break this stratification state, and cannot achieve sufficient convection and exchange of the upper and lower layers of raw materials. The upper light raw materials and the lower heavy raw materials circulate in their respective areas, resulting in uneven distribution of the components of the mixed graphite raw materials and obvious fault problems. This uneven mixing state will seriously affect the performance of subsequent graphite products, such as the charging and discharging performance of battery electrode materials and the physical properties of graphite molds, thereby reducing the quality and consistency of the products. Summary of the invention

[0007] As a further preferred embodiment of the present technical solution, a circular ring is fixedly connected to the bottom of the cross bar, a knocking rod is slidably connected to the mounting plate in the vertical direction, the top of the knocking rod slides in contact with the side wall of the first cam, the positions of the knocking rod and the top of the circular ring are matched with each other, a limiting block is fixedly connected to the outer wall of the knocking rod, and a second damping spring mounted on the knocking rod is arranged between the limiting block and the mounting plate.

[0008] As a further preferred embodiment of the present technical solution, a guide rod is slidably connected to one side of the cross bar, the other end of the guide rod is fixedly connected to the scraper, and a first damping spring sleeved on the guide rod is provided between the cross bar and the scraper.

[0009] As a further preferred embodiment of the present technical solution, vertical grooves are provided around the outer wall of the rotating rod, a rectangular groove is provided on one side of the vertical rod, a reciprocating screw rod is fixedly connected to the inner wall of the rectangular groove, and the thread directions of the two sets of reciprocating screw rods are opposite.

[0010] As a further preferred embodiment of the present technical solution, a rectangular block is threadedly connected to the reciprocating screw, and the rectangular block is slidably installed in the rectangular groove. A movable rod is rotatably connected to one side of the rectangular block, and the other end of the movable rod is slidably installed in the vertical groove, and a cross stirring plate is fixedly installed on the movable rod.

[0011] As a further preferred embodiment of the present technical solution, a fourth gear is fixedly connected to one side of the movable rod, a gear rod is meshingly connected to one side of the fourth gear, and the gear rod is fixedly mounted on the vertical rod.

[0012] As a further preferred embodiment of the present technical solution, a fifth gear is fixedly connected to the bottom of the reciprocating screw rod, and a positioning seat fixedly installed at the bottom of the inner cavity of the mixing tank is rotatably connected to the bottom of the rotating rod. A gear ring meshing with the fifth gear is fixedly connected to the outside of the positioning seat through a connecting rod.

[0013] Compared with the prior art, it has the following beneficial effects: The middle cross stirring plate rotates synchronously under the drive of the servo motor, and can also move up and down reciprocatingly under the cooperation of the third gear and the gear ring. This combination of rotation and up and down reciprocating motion makes the stirring range no longer limited to a fixed plane, but forms a three-dimensional stirring space, which can stir the raw materials in all directions and without dead ends, greatly improving the uniformity of stirring. The up and down reciprocating motion can promote stronger convection and circulation of the raw materials in the stirring container. When the cross stirring plate moves downward, it will squeeze the raw materials at the bottom upward; when it moves upward, it will squeeze the raw materials on the upper part. The material is driven downward, thereby speeding up the flow rate of the raw material, shortening the time required for stirring, and improving the stirring efficiency. The combination of rotation and up and down reciprocating motion will also produce stronger shear force in the raw material, which can effectively break up the lumps and particles in the raw material, make the particle size of the raw material more uniform, and further promote the stirring. While the scraper moves up and down, it can also scrape the inner wall of the stirring container and scrape off the raw material adhering to the inner wall. This can not only prevent the raw material from scaling and agglomerating on the inner wall of the container, affecting the stirring effect and product quality, but also reduce the waste of raw materials and reduce production costs.

[0014] When the first cam rotates, the convex structure of the first cam periodically pushes the knocking rod downward, thereby generating a greater impact force on the ring. This mechanical knocking force can effectively shake off the raw materials, impurities, etc. adhering to the scraper surface. Compared with simple physical scraping or natural falling off, the cleaning effect is more significant, and the amount of residual adherents on the scraper surface can be greatly reduced. The ring transmits the vibration generated by the knocking to the cross bar and the scraper, causing the entire scraper structure to vibrate. The vibration effect can loosen and fall off impurities adhering to the scraper gaps, corners and other hard-to-reach areas, further improving the comprehensiveness and thoroughness of the cleaning.

[0015] A set of reciprocating screws drives the rectangular block, movable rod and cross stirring plate to move upward, and another set of reciprocating screws drives the rectangular block, movable rod and cross stirring plate to move downward. At the same time, due to the meshing of the fourth gear and the toothed rod, the movable rod and the cross stirring plate rotate when moving up and down, so that the two sets of cross stirring plates rotate positively and negatively correspondingly, so that the upper layer of raw materials can be pushed downward and the lower layer of raw materials can be pushed upward, which improves the stirring efficiency and avoids the problem of fault type of raw materials after mixing. The cross stirring plate can rotate synchronously driven by the rotating rod to stir in the horizontal direction, and can also be driven by the reciprocating screw to move up and down. At the same time, it rotates positively and negatively during the up and down movement due to the meshing of the fourth gear and the toothed rod. This multi-directional movement combination makes the raw materials in the stirring container subject to the composite forces in the horizontal, vertical and rotational directions. The materials can be mixed more fully with each other, which greatly shortens the mixing time and improves the mixing efficiency. During the mixing process, due to differences in raw material density, viscosity, etc., stratification of the upper and lower layers is likely to occur. The two sets of cross stirring plates perform corresponding forward and reverse rotations to respectively realize the downward movement of the upper layer of raw materials and the upward movement of the lower layer of raw materials, breaking the stratified state of the raw materials and promoting the convection and exchange between the upper and lower layers of raw materials. This convection effect can fully mix the raw materials at different levels, avoid the problem of fault-type raw materials after mixing, and ensure the consistency of product quality. Continuous up and down convection and forward and reverse rotation stirring can keep the mixing system in a dynamic equilibrium state at all times, preventing the raw materials from being re-stratified during the mixing process. Even if new raw materials are added or the process conditions change during the mixing process, this stirring method can quickly adapt to maintain the stability of the mixing system.

The movable rod 42, the cross rod 43, the scraper 44, the vertical rod 45, and the cross stirring plate 46 rotate synchronously, so that the cross stirring plate 46 stirs the raw materials, and when the worm 415 rotates, it can drive the meshing worm wheel 417 to rotate synchronously, and the worm wheel 417 drives the first cam 418 to rotate synchronously through the first positioning shaft 416, so that the first cam 418 drives the second cam 421, the second positioning shaft 419, and the third gear 420 to reciprocate through the transmission rod 422, so that the reciprocating third gear 420 cooperates with the meshing gear ring 410 to drive the rotating rod 42, the cross rod 43, the scraper 44, the vertical rod 45, the cross stirring plate 46 to stir the raw materials, and when the worm 415 rotates, it can drive the meshing worm wheel 417 to rotate synchronously, and the worm wheel 417 drives the first cam 418 to rotate synchronously through the first positioning shaft 416, so that the first cam 418 drives the second cam 421, the second positioning shaft 419, and the third gear 420 to reciprocate through the transmission rod 422. The stirring plate 46 moves up and down reciprocatingly. While the middle cross stirring plate 46 rotates synchronously and stirs under the drive of the servo motor 412, it can also move up and down reciprocatingly under the cooperation of the third gear 420 and the gear ring 410. This combination of rotation and up and down reciprocating motion makes the stirring range no longer limited to a fixed plane, but forms a three-dimensional stirring space, which can stir the raw materials in all directions and without dead ends, greatly improving the uniformity of stirring. The up and down reciprocating motion can promote stronger convection and circulation of the raw materials in the stirring container. When the cross stirring plate 46 moves downward, the raw materials at the bottom will be squeezed upward;When it moves upward, it will drive the upper raw materials downward, thereby accelerating the flow speed of the raw materials, shortening the time required for stirring, and improving the stirring efficiency. The combination of rotation and up and down reciprocating motion will also generate stronger shear force in the raw materials. This shear force can effectively break up the lumps and particles in the raw materials, making the particle size of the raw materials more uniform, and further promoting the stirring. While the scraper 44 moves up and down, it can also scrape the inner wall of the stirring container and scrape off the raw materials adhering to the inner wall. This can not only prevent the raw materials from scaling and agglomerating on the inner wall of the container, affecting the stirring effect and product quality, but also reduce the waste of raw materials and reduce production costs. The bottom of the cross bar 43 is fixedly connected with a circular ring 438, and the mounting plate 411 is slidably connected with a knocking rod 423 in the vertical direction. The top of the knocking rod 423 slides in contact with the side wall of the first cam 418, and the knocking rod 423 and the top of the circular ring 438 are adapted to each other. The outer wall of the knocking rod 423 is fixedly connected with a limiting block 424, and a second damping spring 425 sleeved on the knocking rod 423 is provided between the limiting block 424 and the mounting plate 411. Under the elastic force of the second damping spring 425, the limiting block 424 is cooperated to push the knocking rod 423 to move upward, so that the top of the knocking rod 423 slides in contact with the first cam 418. When the first cam 418 rotates, when the convex surface of the first cam 418 rotates downward, it can push the knocking rod 423 to move downward and compress the second damping spring 425, so that the knocking rod 4 23. The ring 438 is knocked, so that the ring 438 transmits the vibration to the cross bar 43 and the scraper 44, so that the scraper 44 can be cleaned. When the first cam 418 rotates, the knocking rod 423 is periodically pushed downward by its convex structure, which generates a large impact force on the ring 438. This mechanical knocking force can effectively shake off the raw materials and impurities adhering to the surface of the scraper 44. Compared with simple physical scraping or natural falling off, the cleaning effect is more significant, and the residual amount of the adhering material on the surface of the scraper 44 can be greatly reduced. The ring 438 transmits the vibration generated by the knocking to the cross bar 43 and the scraper 44, so that the entire scraper 44 structure vibrates. The vibration effect can loosen and fall off the impurities adhering to the gaps, corners and other hard-to-reach parts of the scraper 44, further improving the comprehensiveness and thoroughness of the cleaning. A guide rod 47 is slidably connected to one side of the cross bar 43, and the other end of the guide rod 47 is fixedly connected to the scraper 44, and a first damping spring 48 sleeved on the guide rod 47 is arranged between the cross bar 43 and the scraper 44. Under the elastic force of the first damping spring 48, the scraper 44 is pushed to move toward the inner wall of the mixing tank 2, so that the scraper 44 acts on the inner wall of the mixing tank 2. When the rotating rod 42 drives the cross bar 43 and the scraper 44 to rotate, the scraper 44 scrapes the inner wall of the mixing tank 2. The first damping spring 48 pushes the scraper 44 to stick to the inner wall, and the scraper 44 is continuously rotated and scraped under the drive of the rotating rod 42, which can effectively prevent the raw materials from staying on the inner wall for a long time and agglomerating or forming dead zones, ensuring that all raw materials can fully participate in the stirring and mixing process, and improving the uniformity of mixing. The scraping action of the scraper 44 makes the raw materials on the inner wall return to the main stirring area, forming a good raw material circulation. This circulating flow helps to break the stratification and agglomeration between the raw materials, accelerate the mutual penetration and fusion between different components, shorten the mixing time, and improve the mixing efficiency.

[0020] In the embodiment of the present invention, the servo motor 412 drives the connecting rod 413 to rotate synchronously, the connecting rod 413 drives the second gear 414 and the worm 415 to rotate synchronously, and the second gear 414 drives the meshing first gear 49 to rotate in the opposite direction, so that the first gear 49 drives the sleeve rod 41, the rotating rod 42, the cross bar 43, the scraper 44, the vertical rod 45, and the cross stirring plate 46 to rotate synchronously, so that the cross stirring plate 46 stirs the raw materials, and when the worm 415 rotates, it can drive the meshing worm wheel 417 to rotate synchronously, and the worm wheel 417 The first cam 418 is driven to rotate synchronously by the first positioning shaft 416, so that the first cam 418 drives the second cam 421, the second positioning shaft 419, and the third gear 420 to reciprocate through the transmission rod 422, so that the reciprocating third gear 420 cooperates with the meshing gear ring 410 to drive the rotating rod 42, the cross rod 43, the scraper 44, the vertical rod 45, and the cross stirring plate 46 to reciprocate up and down. While the middle cross stirring plate 46 is driven by the servo motor 412 to rotate synchronously and stir, the third gear 420 and the meshing gear ring 410 can also be used to rotate synchronously. The gear ring 410 is cooperated with to move up and down reciprocatingly. This combination of rotation and up and down reciprocating motion makes the stirring range no longer limited to a fixed plane, but forms a three-dimensional stirring space, which can stir the raw materials in an all-round and dead angle-free manner, greatly improving the uniformity of stirring. The up and down reciprocating motion can promote the raw materials to produce stronger convection and circulation in the stirring container. When the cross stirring plate 46 moves downward, it will squeeze the raw materials at the bottom upward; when it moves upward, it will drive the upper raw materials downward, thereby accelerating the flow speed of the raw materials, shortening the time required for stirring, and improving the stirring efficiency. The combination of rotation and up and down reciprocating motion will also produce stronger shear force in the raw materials. This shear force can effectively break up the lumps and particles in the raw materials, make the particle size of the raw materials more uniform, and further promote the stirring. While the scraper 44 moves up and down, it can also scrape the inner wall of the stirring container and scrape off the raw materials adhering to the inner wall. This can not only prevent the raw materials from scaling and agglomerating on the inner wall of the container, affecting the stirring effect and product quality, but also reduce the waste of raw materials and reduce production costs. When the convex surface of the first cam 418 rotates downward, it can push the knocking rod 423 to move downward and compress the second damping spring 425, so that the knocking rod 423 knocks the ring 438, so that the ring 438 transmits the vibration to the cross bar 43 and the scraper 44, so that the scraper 44 can be cleaned. When the first cam 418 rotates, its convex surface structure periodically pushes the knocking rod 423 to move downward, generating a large impact force on the ring 438. This mechanical knocking force can effectively shake off the raw materials, impurities, etc. adhering to the surface of the scraper 44. Compared with simple physical scraping or natural falling off, the cleaning effect is more significant, and the residual amount of the adhering material on the surface of the scraper 44 can be greatly reduced. The ring 438 transmits the vibration generated by the knocking to the cross bar 43 and the scraper 44, so that the entire scraper 44 structure vibrates. The vibration effect can loosen and fall off the impurities adhering to the hard-to-reach parts such as the gaps and corners of the scraper 44, further improving the comprehensiveness and thoroughness of the cleaning. Under the elastic force of the first damping spring 48, the scraper 44 is pushed to move toward the inner wall of the mixing tank 2, so that the scraper 44 acts on the inner wall of the mixing tank 2. When the rotating rod 42 drives the cross bar 43 and the scraper 44 to rotate, the scraper 44 scrapes the inner wall of the mixing tank 2. The first damping spring 48 pushes the scraper 44 to stick to the inner wall. Driven by the rotating rod 42, the scraper 44 continues to rotate and scrape, which can effectively prevent the raw materials from staying on the inner wall for a long time and forming lumps or dead zones, ensuring that all raw materials can fully participate in the stirring and mixing process, improving the uniformity of mixing, and the scraping action of the scraper 44 makes the raw materials on the inner wall return to the main stirring area, forming a good raw material circulation. This circulating flow helps to break the stratification and agglomeration between the raw materials, accelerate the mutual penetration and fusion between different components, shorten the mixing time, and improve the mixing efficiency.

[0021] Embodiment 2: Combination Figure 6 , Figure 7 , Figure 8As shown, on the basis of the first embodiment, vertical grooves 426 are provided around the outer wall of the rotating rod 42, and a rectangular groove 428 is provided on one side of the vertical rod 45. A reciprocating screw rod 429 is fixedly connected to the inner wall of the rectangular groove 428, and the thread directions of the two groups of reciprocating screw rods 429 are opposite, that is, one group of reciprocating screw rods 429 drives the rectangular block 430 and the cross stirring plate 46 to move upward, and the other group drives the rectangular block 430 and the cross stirring plate 46 to move downward, and the reciprocating screw rod 429 is threadedly connected with the rectangular block 430, and the rectangular block 430 is slidably installed in the rectangular groove 428, one side of the rectangular block 430 is rotatably connected with a movable rod 431, the other end of the movable rod 431 is slidably installed in the vertical groove 426, and the cross stirring plate 46 is fixedly installed on the movable rod 431; one side of the movable rod 431 is fixedly connected with a fourth gear 433, and one side of the fourth gear 433 is meshingly connected with a gear rod 434, and the gear rod 434 is fixedly installed on the vertical rod 45;The bottom of the reciprocating screw 429 is fixedly connected to a fifth gear 435, and the bottom of the rotating rod 42 is rotatably connected to a positioning seat 436 fixedly installed at the bottom of the inner cavity of the mixing tank 2. The outer side of the positioning seat 436 is fixedly connected to a gear ring 437 meshing with the fifth gear 435 through a connecting rod. When the rotating rod 42 drives the vertical rod 45 to rotate synchronously, the fifth gear 435 rotates around the gear ring 437, so that the gear ring 437 drives the reciprocating screw 429 to rotate synchronously, so that a group of reciprocating screws 429 drives the rectangular block 430, the movable rod 431, and the cross stirring plate 46 to move upward. The other set of reciprocating screw rods 429 drives the rectangular block 430, the movable rod 431, and the cross stirring plate 46 to move downward. At the same time, due to the meshing of the fourth gear 433 and the gear rod 434, the movable rod 431 and the cross stirring plate 46 rotate when moving up and down, so that the two sets of cross stirring plates 46 perform corresponding positive and negative rotations, thereby realizing the downward shifting of the upper layer of raw materials and the upward shifting of the lower layer of raw materials, improving the stirring efficiency while avoiding the problem of the fault type of the mixed raw materials. The cross stirring plate 46 can rotate synchronously under the drive of the rotating rod 42 to perform water mixing. The stirring in the horizontal direction can be driven by the reciprocating screw 429 to move up and down. At the same time, the fourth gear 433 and the gear rod 434 are meshed in the process of moving up and down, and the fourth gear 433 and the gear rod 434 rotate forward and reversely. This multi-directional movement combination makes the raw materials in the stirring container subject to the composite force in the horizontal, vertical and rotational directions, and can be more fully mixed with each other, greatly shortening the mixing time and improving the stirring efficiency. During the stirring process, due to differences in raw material density, viscosity, etc., the upper and lower layers are prone to stratification. The two groups of cross stirring plates 46 perform corresponding forward and reverse rotations to respectively realize the downward movement of the upper layer of raw materials and the upward movement of the lower layer of raw materials, breaking the stratified state of the raw materials and promoting the convection and exchange between the upper and lower layers of raw materials. This convection can fully mix the raw materials at different levels, avoid the problem of fault-type raw materials after mixing, and ensure the consistency of product quality. Continuous up and down convection and forward and reverse rotation stirring can keep the mixing system in a dynamic equilibrium state at all times, preventing the raw materials from being re-stratified during the stirring process. Even if new raw materials are added or the process conditions change during the stirring process, this stirring method can quickly adapt to maintain the stability of the mixing system. ;

[0022] In the embodiment of the present invention, when the rotating rod 42 drives the vertical rod 45 to rotate synchronously, the fifth gear 435 rotates around the gear ring 437, so that the gear ring 437 drives the reciprocating screw rod 429 to rotate synchronously, so that one group of reciprocating screw rods 429 drives the rectangular block 430, the movable rod 431, and the cross stirring plate 46 to move upward, and the other group of reciprocating screw rods 429 drives the rectangular block 430, the movable rod 431, and the cross stirring plate 46 to move downward. At the same time, due to the engagement of the fourth gear 433 with the gear rod 434, the movable rod 431 and the cross stirring plate 46 rotate when moving up and down, so that the two groups of cross stirring plates 46 perform corresponding positive and negative rotations, so that the upper layer of raw materials can be pushed downward and the lower layer of raw materials can be pushed upward, thereby improving the stirring efficiency and avoiding the problem of fault type of the mixed raw materials. The cross stirring plate 46 can not only rotate synchronously under the drive of the rotating rod 42 to stir in the horizontal direction, but also can be driven by the reciprocating screw rod 429 to move up and down. At the same time, during the up and down movement, due to the engagement of the fourth gear 433 with the gear rod 434, the movable rod 431 and the cross stirring plate 46 rotate The four gears 433 mesh with the gear rod 434 and rotate forward and backward. This multi-directional movement combination causes the raw materials in the mixing container to be subjected to the combined forces in the horizontal, vertical and rotational directions, so that they can be mixed more fully with each other, greatly shortening the mixing time and improving the mixing efficiency. During the mixing process, due to differences in the density and viscosity of the raw materials, stratification of the upper and lower layers is likely to occur. The two groups of cross stirring plates 46 perform corresponding forward and reverse rotations to respectively realize the downward movement of the upper layer of raw materials and the upward movement of the lower layer of raw materials, breaking the stratified state of the raw materials and promoting convection and exchange between the upper and lower layers of raw materials. This convection effect can fully mix the raw materials at different levels, avoid the problem of fault-type raw materials after mixing, and ensure the consistency of product quality. Continuous up and down convection and forward and reverse rotation stirring can keep the mixing system in a dynamic equilibrium state at all times, preventing the raw materials from being re-stratified during the mixing process. Even if new raw materials are added or the process conditions change during the mixing process, this stirring method can quickly adapt to maintain the stability of the mixing system.
