Description

Technical Field

[0001] This invention relates to the field of conveying mechanism technology, specifically to a feeding assembly and method for a horizontal ribbon mixer. Background Technology

[0002] As a key upstream unit of the horizontal ribbon mixer, the feeding assembly is responsible for conveying and distributing the various raw materials to be mixed into the mixer. Its performance directly determines the efficiency, quality and stability of the entire production system.

[0003] In the production of battery materials, especially high-value-added and highly active materials such as cathode materials, more stringent requirements are placed on the feeding process: First, it is essential to effectively remove any ferromagnetic or other metallic impurities that may be mixed into the raw materials to prevent them from puncturing the battery separator and causing safety hazards such as short circuits; second, since cathode material raw materials are mostly micron or nano-sized powders, they are highly susceptible to moisture absorption, oxidation, and bridging and clumping due to van der Waals forces during transportation, which not only affects transportation efficiency but also leads to a decrease in the mixing uniformity of the final product; in addition, to ensure the consistency of battery performance, cross-contamination between batches must be avoided during the production process.

[0004] Currently, existing feeding technologies typically employ independent screw conveyors, pneumatic conveying systems, or simple gravity discharge methods. These traditional solutions have significant drawbacks: First, the iron removal process is often separate from the conveyor line, requiring additional iron removal equipment, resulting in a long process flow, large equipment footprint, and the risk of secondary contamination during material transfer. Second, while conventional pneumatic conveying can achieve closed-loop transport, it is ineffective for easily agglomerated nanoparticles, which tend to adhere to and remain on the inner wall of the pipe, causing material loss and cleaning difficulties. Furthermore, it lacks effective inert gas protection for the material during transport. Third, a common solution to the powder bridging problem is to install a mechanical stirring and arch-breaking device in the silo, but this device has a complex structure and carries the risk of introducing abrasive particles. Fourth, after feeding, existing systems often leave material residue in the pipes, causing waste and potentially leading to cross-contamination between different batches of products, affecting product purity. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding assembly and method for a horizontal ribbon mixer, so as to achieve the purpose of safely conveying raw materials for battery processing and to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding assembly for a horizontal ribbon mixer, comprising: Mounting base for fixing on a horizontal ribbon mixer; The main feed pipe is installed on the mounting base. Its inlet is used to receive materials, and its outlet is connected to the feed pipe via a magnetic separator. The outlet of the feed pipe leads to the mixing chamber of the horizontal ribbon mixer. The gas supply system includes a main gas pipe connected to the main feed pipe, used to introduce inert gas into the main feed pipe to form pneumatic conveying. The ball circulation system includes a recirculating ball, an inclined screen plate installed in the feed pipe, a guide pipe, and a quick-connect mechanism. The ball is installed in the main feed pipe and moves with the material and airflow to break up material agglomeration. The inclined screen plate is used to separate the ball from the material flow. The guide pipe is used to transport the ball separated by the inclined screen plate from the feed pipe back to the main feed pipe to form a circulation path. The quick-connect mechanism is used to realize the quick connection and disconnection between the guide pipe, the main feed pipe, and the feed pipe. The cleaning and recycling system includes a recycling pipe located at the lowest point of the main feed pipe and a backflushing pipe connected to the feed pipe. The gas supply system can introduce gas into the pipeline through the main gas supply pipe and the backflushing pipe, so that the residual material is discharged through the recycling pipe.

[0007] The mounting base includes an isolation support plate, a enclosure, and a top seat. The isolation support plate and the top seat are fixed to the upper and lower sides of the enclosure, respectively. The isolation support plate is used to fix the top of the horizontal ribbon mixer and close its mixing chamber.

[0008] The main feeding pipe has an arc-shaped bend structure with its inlet set vertically upward and its outlet set horizontally towards the inlet after turning through the pipeline, so that the material is conveyed by swirling upward within the pipe.

[0009] The iron remover is an electromagnetic iron remover, and its bottom is equipped with a drain port for removing adsorbed impurities.

[0010] The ball is a hollow, rigid plastic ball.

[0011] The quick-connect mechanism includes rings fixed to both ends of the guide tube, springs sleeved on the guide tube, and sealing sleeves connected to the springs and movable along the ends of the guide tube. Under the action of the spring, the sealing sleeve can extend outward and form a sealed connection with the joints provided on the feed pipe and the main feed pipe.

[0012] The connector is equipped with a valve, and a gear is installed on the valve stem. The sealing sleeve is equipped with a rack that meshes with the gear; when the sealing sleeve is connected to the connector, the rack drives the gear to rotate, thereby opening the valve.

[0013] The guide tube is fixed to the mounting base by a mounting bracket; the mounting bracket is provided with an end seat, and a pin is slidably mounted on the end seat. The mounting base is equipped with a fixed seat with holes; when the quick-connect mechanism completes the connection, the pin is inserted into the hole of the fixed seat under the drive of the linkage mechanism to achieve quick fixation of the mounting bracket.

[0014] The ball circulation system also includes an anti-clogging mechanism, which includes a swing arm rotatably mounted on the inclined screen plate, a traction rope connected to the swing arm, and a suspension component connected to the traction rope. The lifting component is suspended in the material flow channel of the feed pipe. It swings under the impact of airflow and material. The swing arm swings through the traction rope, which pushes the rolling ball towards the inlet of the guide pipe.

[0015] A method for using the feeding assembly of a horizontal ribbon mixer includes the following steps: S1, feeding: Inert gas is introduced into the main feeding pipe through the gas supply system to form a pneumatic conveying flow, which drives the material and the rolling ball to move in the main feeding pipe. During this process, the material enters the feed pipe and is finally sent into the mixing chamber of the horizontal ribbon mixer after the iron remover removes ferromagnetic impurities. S2, Ball Separation and Circulation: In the feed pipe, the balls that have completed the arch-breaking action are separated from the material flow by the inclined screen plate. The separated balls are returned to the main feed pipe through the guide pipe and the quick-connect mechanism in the connected state to form the circulation path of the balls. S3, Cleaning and Recycling: After the feeding process is completed, gas is simultaneously introduced into the main gas pipe and the backflushing pipe through the gas supply system. The bidirectional airflow is used to flush the main feeding pipe and the feed pipe, so that the residual material in the pipeline is discharged from the system through the recycling pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By introducing inert gas protection and the synergistic effect of rigid plastic rolling balls in the main feed pipe, not only is the oxidation and deterioration of battery materials during transportation effectively prevented, but the mechanical collision of the rolling balls also efficiently solves the problems of powder bridging and agglomeration. The unique annular pipe layout combined with the electromagnetic iron separator constitutes a continuous iron removal system, which simultaneously completes the deep purification of ferromagnetic impurities during transportation, fundamentally eliminating the harm of metallic foreign objects to battery safety.

[0017] 2. The automatic ball recycling mechanism of the present invention achieves closed-loop recycling of the balls through inclined screen plate separation, pneumatic trigger quick-connect guide tube and swing rod actuation system, which avoids external pollution and ensures clean production.

[0018] 3. The system achieves self-cleaning through the combination of bidirectional airflow flushing and recycling pipelines, significantly reducing residual materials while improving production stability between different batches; the entire system achieves multi-functional integration of feeding, iron removal, recycling, and cleaning without the need for complex electrical control through precise coordination of mechanical linkage and airflow control, greatly improving the reliability, safety, and production efficiency of the horizontal ribbon mixer in battery material production, while reducing energy consumption and maintenance costs.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 10 This invention provides a technical solution: a feeding assembly for a horizontal ribbon mixer, which can be used in an intelligent heat treatment production line for battery material processing. The feeding assembly has a basic installation structure, including an isolation support plate 1, a enclosure 2, and a top seat 3. The isolation support plate 1 and the top seat 3 are welded and fixed to the upper and lower sides of the enclosure 2, respectively. Both the isolation support plate 1 and the top seat 3 are flat plate structures, and the enclosure 2 serves as a support and connection between the two. The isolation support plate 1 can be fixed to the top of the horizontal ribbon mixer with screws and can seal the internal mixing chamber of the horizontal ribbon mixer. This horizontal ribbon mixer is mainly used for the mixing and preparation of positive electrode materials and can mix powder raw materials such as active materials and conductive agents.

[0032] The main feed pipe 4 is installed through the top seat 3 by screws. The main feed pipe 4 has an arc-shaped bend structure. Its inlet is set vertically upward, and after the pipe turns, the outlet is set horizontally towards the inlet. Therefore, the powder raw materials for battery processing can be conveyed by spiraling upward in the main feed pipe 4.

[0033] Furthermore, a magnetic separator 5 is fixedly installed at the outlet of the main feed pipe 4 via a flange. Electrode processing materials can pass through the magnetic separator 5. The magnetic separator 5 adopts an electromagnetic structure, which can effectively remove ferromagnetic impurities from the powder raw materials. The bottom of the magnetic separator 5 is provided with a drain port to remove impurities, preventing metal impurities from mixing with the positive electrode material, ensuring the quality of battery processing, and preventing metal impurities from piercing the battery separator and causing a short circuit. At the outlet of the magnetic separator 5, an inlet pipe 6 is fixedly installed at the outlet via a flange. The inlet pipe 6 is fixed to the top seat 3 in a vertical manner. The powder raw materials after impurity removal can enter the inlet pipe 6. The bottom of the inlet pipe 6 is integrally formed with a branched distribution pipe 7. The distribution pipe 7 can be staggered from the main feed pipe 4, and the distribution pipe 7 passes through the isolation support plate 1 and enters the mixing chamber of the horizontal ribbon mixer, so that the powder raw materials entering the inlet pipe 6 can be finally transported into the mixing chamber for mixing processing.

[0034] A recovery pipe 8 is connected at the lowest position of the main feed pipe 4. The recovery pipe 8 is inclined and equipped with a solenoid valve. When the feeding assembly conveys raw materials, the recovery pipe 8 can be closed. After the conveying is completed, the solenoid valve can be opened to open the recovery pipe 8 so as to recover the powder raw materials that have not been processed by the iron remover 5 from this position.

[0035] This invention utilizes high-pressure protective gas for the swirling conveying and recovery of powder raw materials. A main gas supply pipe 9 is connected near the inlet of the main feed pipe 4, and a backflushing pipe 10 is connected near the iron separator 5 in the feed pipe 6. Both the main gas supply pipe 9 and the backflushing pipe 10 are externally connected to a high-pressure protective gas tank. When the powder raw materials are conveyed into the horizontal ribbon mixer through the feeding assembly, protective gas is input into the main feed pipe 4 through the main gas supply pipe 9. The protective gas is usually an inert gas such as nitrogen, which serves to prevent oxidation of the raw materials and generate sufficient pressure to move the powder raw materials along the direction of the main feed pipe 4, overcoming gravity to move into the iron separator 5 for impurity removal. After the conveying is completed, considering the presence of raw material residue in the main feed pipe 4, the recovery pipe 8 can be opened, and the main gas supply pipe 9 and the backflushing pipe 10 work simultaneously to generate gas to flush the residue, allowing the residual powder to be recovered through the recovery pipe 8.

[0036] Considering that active materials and conductive agents contain materials such as carbon black that are prone to sticking and bridging, which affect the gas conveying effect and easily cause raw material residue, hollow hard plastic balls are added to the main feed pipe 4. These balls can move with the powder raw materials, impacting and breaking up the agglomerated and bridging materials, promoting their swirling conveying. Furthermore, a separate ball channel is set between the feed pipe 6 and the main feed pipe 4 to prevent the balls from entering the distribution pipe 7 and then into the mixer.

[0037] An L-shaped upper connector 11 is installed on one side of the feed pipe 6 by welding, and a vertical lower connector 12 is installed at the bottom of the main feed pipe 4 by welding. The openings of the upper connector 11 and the lower connector 12 are arranged on the same straight line. A guide pipe 13 can be installed between the upper connector 11 and the lower connector 12. In the vertical pipe of the feed pipe 6, an inclined screen plate 28 is fixedly installed by screws. The bottom end of the inclined screen plate 28 is set close to the upper connector 11. The powder raw material can pass through the screen hole, and the rolling ball can roll down along the inclined screen plate 28 into the upper connector 11, so that the rolling ball enters the main feed pipe 4 from the upper connector 11, the guide pipe 13, and the lower connector 12.

[0038] The guide tube 13 is provided with a movable quick-connect docking structure at both ends, which includes a ring sleeve 14 fixedly installed at both ends of the guide tube 13. A spring 15 is installed on the ring sleeve 14 by a pin. The spring 15 is sleeved on the guide tube 13. A sealing sleeve 16 is movably installed at both ends of the guide tube 13. The sealing sleeve 16 is connected to the spring 15 by a pin. Therefore, under the action of the spring 15, the sealing sleeve 16 can extend to both ends. The two sealing sleeves 16 can be sealed and connected to the upper connector 11 and the lower connector 12 respectively to prevent the powder raw material and the ball from being lost.

[0039] Meanwhile, valves 17 are also installed in the upper connector 11 and the lower connector 12. When the guide tube 13 is not installed, the connector can be closed by the valve 17. A gear 18 is fixedly installed on the valve stem of the valve 17, and a rack 19 is correspondingly installed on the sealing sleeve 16. When the sealing sleeve 16 is fitted on the upper connector 11 and the lower connector 12, the rack 19 can drive the gear 18 to open the valve 17, so that when the guide tube 13 is installed, the upper connector 11, the guide tube 13, and the lower connector 12 are automatically connected.

[0040] In addition to using movable quick-release upper and lower connectors, the guide tube 13 is fixedly installed in the mounting bracket 20 with screws, and can be quickly fixed to the top seat 3 for use via the mounting bracket 20.

[0041] The mounting bracket 20 is horizontally positioned, and the guide tube 13 is vertically mounted at its front end. The rear end of the mounting bracket 20 is integrally formed with an end seat 21. A pin 22 is mounted on the end seat 21 by means of a sliding groove. A fixed seat 23 with a hole is fixedly mounted on the top seat 3. The pin 22 can be inserted into the fixed seat 23 for fixation. An inclined push surface 24 is provided on the side of the pin 22 facing away from the fixed seat 23. The pin 22 is controlled by the inclined push surface 24.

[0042] A pull rod 25 is slidably mounted in the mounting bracket 20. The front end of the pull rod 25 is positioned near the guide tube 13, and a pull rope 26 is fixedly connected to it. The pull rope 26 passes through the ring sleeve 14 and is connected to the sealing sleeve 16. The rear end of the pull rod 25 is fixedly mounted with a top plate 27 by screws. Under the action of the spring 15, the sealing sleeve 16 can connect with the upper and lower joints, and at the same time, the pull rope 26 is pulled. The pull rope 26 pulls the top plate 27, and the top plate 27 is movably connected to the inclined push surface 24 of the pin 22. Under the action of the top plate 27, the pin 22 can be pushed towards the fixed seat 23, so that it can be inserted into the fixed seat 23 to complete the fixation of the guide tube 13. When the guide tube 13 is initially inserted, the top plate 27 can be driven in the opposite direction by pushing the pin 22, which will cause the sealing sleeve 16 to retract, so as to avoid interference with the upper connector 11 and the lower connector 12. Finally, after the pin 22 is released, the sealing sleeve 16 can be connected to the two connectors, and the pin 22 is also connected to the fixed seat 23 at the same time.

[0043] Therefore, the guide tube 13 can be easily removed for cleaning, preventing powder from accumulating inside.

[0044] Furthermore, a swing rod 29 is rotatably mounted on the inclined screen plate 28. The swing rod 29 has an arc-shaped rod structure, with one end mounted on the inclined screen plate 28 near the upper connector 11 via a rotating shaft, and the other end being a movable end. A traction rope 30 is fixedly connected to the movable end of the swing rod 29. The traction rope 30 is connected to a suspension rope 31, which passes through the screen holes of the inclined screen plate 28 and enters the area below the inclined screen plate 28. A lifting component 32 is installed at the bottom end of the suspension rope 31. At the same time, an elastic rope 33 is connected to the suspension rope 31, and the other end of the elastic rope 33 is connected to... Connected to the upper connector 11, during the conveying of powder raw materials, the airflow and powder can generate fluctuating downward pressure on the lifting member 32, causing the lifting member 32 to intermittently pull down the lifting rope 31, thereby driving the swing arm 29 to swing and push the rolling ball towards the middle of the inclined screen plate 28, guiding it into the upper connector 11. At the same time, the movement of the lifting rope 31 can drive the elastic rope 33 to move. The elastic rope 33 provides a restoring elastic force on the one hand, and on the other hand, it can move the rolling ball when it moves, preventing the rolling ball from accumulating and blocking in the upper connector 11.

[0045] In use, this invention works as follows: First, high-pressure inert gas is introduced into the main feed pipe 4 through the main gas pipe 9, forming a pneumatic conveying system. The gas drives the battery material powder and hollow hard plastic balls to rotate and rise within the main feed pipe 4. During the conveying process, the balls continuously impact the agglomerated materials, breaking up bridging. The powder passes through the electromagnetic separator 5 during pneumatic conveying, where ferromagnetic impurities are strongly adsorbed and removed, ensuring the purity of the electrode material. The purified powder enters the feed pipe 6 with the airflow, and after being filtered and separated by the inclined screen plate 28, the powder falls through the sieve holes into the distribution pipe 7 and finally enters the mixing chamber. The balls roll along the inclined surface of the inclined screen plate 28 into the upper connector 11 for recirculation. At this time, the mounting bracket 20 is quickly locked to the fixing seat 23 by the pin 22, and the sealing sleeves 16 at both ends of the guide pipe 13 are locked to the upper and lower connectors by the action of the spring 15. The head forms a sealed connection, and at the same time, the rack 19 on the sealing sleeve 16 drives the gear 18 to automatically open the valve 17, establishing a complete ball return channel. Under the action of gravity, the ball returns to the inlet end of the main feed pipe 4 through the guide pipe 13 for recycling. When the conveying process ends, the main air supply pipe 9 and the backflushing pipe 10 are opened simultaneously, and the bidirectional airflow is used to thoroughly flush the main feed pipe 4 and the feed pipe 6. The residual powder is collected and recycled through the recovery pipe 8. During the entire working process, the airflow fluctuation causes the hanging part 32 to move up and down periodically. The traction rope 30 drives the swing arm 29 to swing back and forth, continuously pushing the ball towards the inlet of the guide pipe 13. At the same time, the elastic deformation of the elastic rope 33 generates continuous disturbance, effectively preventing the ball from accumulating and blocking at the upper joint 11, realizing the coordinated operation of automatic ball circulation and pipeline self-cleaning, and ensuring the continuous and stable operation of the system.
