Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to a lithium battery positive pressure pneumatic conveying device. Background Technology

[0002] Powder pneumatic conveying is a technology that uses airflow energy to transport powdery or granular materials in a closed pipeline along the airflow direction. It uses compressed air or gas as power to transport materials from one location to another. Driven by airflow, it eliminates the need for mechanical transmission components, significantly reducing the frequency of equipment maintenance and replacement, resulting in low operating costs and advantages such as high efficiency, safety, and environmental friendliness.

[0003] In the lithium battery production process, the conveying and transfer of various electrode powders, conductive agents, binders, and other powdered raw materials is a critical step. Pneumatic conveying, with its advantages of closed conveying, low material loss, and strong adaptability, has become the mainstream method for conveying lithium battery powder materials. Positive pressure pneumatic conveying uses compressed air to propel the powder movement, enabling long-distance and large-volume material conveying. The equipment has a simple structure and few mechanical transmission parts, which can effectively reduce material crushing and breakage, meeting the requirements of lithium battery raw material processing and production.

[0004] Existing conventional positive pressure conveying equipment for lithium battery powder has significant shortcomings in practical applications. Lithium battery powder has a fine texture and is highly prone to adsorption, agglomeration, and adhesion to the inner walls of conveying pipes. Long-term operation can easily lead to pipe blockages, forcing production shutdowns for maintenance, severely reducing production continuity and increasing maintenance costs. Traditional equipment has a centralized feeding point, making it difficult for auxiliary materials to fully integrate with the main material, resulting in poor material uniformity and directly affecting the consistency of subsequent battery performance. Furthermore, most conveying devices on the market have a constant feeding rate, unable to flexibly adjust the feeding speed according to the mixing conditions, making it difficult to control the mixing quality. Separate and independent drives for mixing, anti-blocking, and feeding mechanisms result in numerous power components, high overall energy consumption, and a higher mechanical failure rate. In addition, the equipment's simple sealing and protection structure makes it prone to dust emission during operation, causing not only raw material waste but also pollution of the workshop environment and even dust safety hazards, failing to meet the high standards of clean, stable, and safe conveying operations required for lithium battery production.

[0005] Therefore, a lithium-ion battery positive pressure pneumatic conveying device needs to be designed to solve the above problems. Summary of the Invention

[0006] The purpose of this application is to provide a lithium battery positive pressure pneumatic conveying device to solve the above-mentioned problems.

[0007] The above-mentioned technical objective of this application is achieved through the following technical solution: a lithium battery positive pressure pneumatic conveying device, comprising: A conveying pipe, wherein an anti-clogging mixing mechanism is provided on the conveying pipe; The anti-clogging mixing mechanism includes a lithium battery powder tank, a top frame, a power motor, a reciprocating lead screw, a reciprocating lead screw sleeve, a sleeve plate, a connector, a crossbar, and a rubber ball; The top frame is fixedly installed on the top of the lithium battery powder tank, the power motor is fixedly installed on the top of the top frame, the output end of the power motor is fixedly connected to the reciprocating lead screw, the reciprocating lead screw is driven by the reciprocating lead screw sleeve, the sleeve plate is fixedly installed on the reciprocating lead screw sleeve, the connecting piece is fixedly connected to the sleeve plate and the crossbar, and the rubber ball is fixedly installed at the bottom of the crossbar.

[0008] Optionally, the anti-clogging mixing mechanism further includes a first shaft, a second shaft, a stirring blade, a sealed bearing, a tube, a storage tank, a first seal, a second seal, a guide tube, and a discharge pipe. The first shaft is fixedly installed at the bottom of the reciprocating screw, the stirring blade is fixedly installed on the outside of the second shaft, both the first and second shafts are equipped with sealed bearings, the tube is installed between the two sealed bearings, the storage tank is fixedly installed on the lithium battery powder tank, the guide tube is fixedly installed on the storage tank and the tube, both the first and second seals are slidably and sealingly installed on the lithium battery powder tank, the second seal is in sealing contact with the guide tube, and the discharge pipe is fixedly installed on the second shaft.

[0009] Optionally, the top of the shaft body is provided with a circular hole, which is connected to the inside of the tube body, and the discharge pipe is connected to the inside of the tube body.

[0010] By adopting the above technical solution, the flow of powder is facilitated.

[0011] Optionally, there may be multiple discharge pipes, and the lengths of the multiple discharge pipes may be different.

[0012] By adopting the above technical solution, this device uses multiple discharge pipes of different lengths to divert the discharge, allowing the auxiliary powder to be dispersed and sprinkled from different depths and positions inside the tank, replacing the traditional single-point centralized feeding method. This results in a wider feeding coverage and more uniform material distribution, effectively avoiding the problems of concentrated accumulation of auxiliary materials and local high proportions. It improves the mixing foundation of main materials and auxiliary materials from the source of feeding, and significantly reduces the probability of material stratification and agglomeration.

[0013] Optionally, a discharge pipe is fixedly installed at the bottom of the lithium battery powder tank, the discharge pipe is fixedly installed on the conveying pipe, and a solenoid valve is installed on the discharge pipe.

[0014] By adopting the above technical solution, the solenoid valve is opened, which facilitates the transportation of the mixed materials to the conveying pipe for processing. The discharge pipe is arranged above the stirring blades, and the spilled auxiliary materials can fall directly into the stirring and agitation area. During the falling process, they can fully contact and mix with the main materials. With the rotation and stirring action of the stirring blades, the material falling, mixing and homogenization are carried out simultaneously, resulting in higher mixing efficiency and better material uniformity. This effectively ensures that the lithium battery powder ratio is consistent and the texture is uniform in each batch, thus ensuring the performance stability of subsequent battery products.

[0015] Optionally, the sleeve is slidably fitted onto the outside of the top frame.

[0016] By adopting the above technical solution, the sleeve plate can move stably vertically. The sleeve plate is slidably sleeved on the outside of the top frame, and the top frame is used to realize vertical sliding limit guidance, effectively limiting the horizontal swaying and displacement of the sleeve plate, and ensuring that the sealing element pushes accurately and stably.

[0017] Optionally, a Roots blower is fixedly installed at the end of the conveying pipe.

[0018] By adopting the above technical solution and using the end Roots blower to provide a stable positive pressure air source, the pneumatic conveying power is sufficient and the airflow is uniform, which can realize the closed, continuous and stable conveying of lithium battery powder, with stable conveying flow and no material retention, effectively improving the powder conveying efficiency.

[0019] Optionally, the top of the lithium battery powder container is provided with an L-shaped hole, and both sealing element one and sealing element two are slidably sealed in the L-shaped hole, which is filled with hydraulic oil.

[0020] By adopting the above technical solution, through the L-shaped hole at the top of the lithium battery powder tank and the internal hydraulic oil pressure transmission design, the reciprocating motion of the sleeve plate can drive the linkage displacement of seal one and seal two, automatically and dynamically adjust the feed flow of the conduit, and realize the adaptive change of the feed rate with the stirring rhythm.

[0021] Optionally, an addition tube is fixedly installed on the top of the storage tank, and a threaded cap is threadedly connected to the addition tube.

[0022] Optionally, the discharge pipe is located above the stirring blades.

[0023] The beneficial effects of this application are: The present application uses a motor to drive a reciprocating screw, which causes a rubber ball to repeatedly impact the wall of the conveying pipe. The vibration breaks up the powder that adheres and accumulates, effectively preventing pipe blockage, reducing the frequency of downtime for unblocking, and greatly improving the continuity of lithium battery powder conveying operations. The different lengths of the discharge pipes in this application allow for multi-point decentralized feeding, and with the high-speed stirring of the mixing blades, the main materials and auxiliary materials can be fully mixed; the feeding speed is dynamically adjusted by hydraulic transmission and linkage between sealing component one and sealing component two, resulting in high material mixing uniformity and ensuring stable quality of lithium battery powder finished products. The device integrates feeding, mixing, anti-clogging, and positive pressure conveying functions, eliminating the need for material transfer. The Roots blower provides a stable positive pressure airflow to push the material, simplifying the production process, shortening the operation time, and effectively improving the overall production and conveying efficiency.

[0036] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] See Figures 1-10 This application provides a lithium battery positive pressure pneumatic conveying device, comprising: Conveying pipe 1, which is equipped with an anti-clogging mixing mechanism; The anti-clogging mixing mechanism includes a lithium battery powder tank 2, a top frame 3, a power motor 4, a reciprocating screw 5, a reciprocating screw sleeve 11, a sleeve plate 12, a connector 13, a crossbar 14, and a rubber ball 15; The top frame 3 is fixedly installed on the top of the lithium battery powder tank 2. The power motor 4 is fixedly installed on the top of the top frame 3. The output end of the power motor 4 is fixedly connected to the reciprocating screw 5. The reciprocating screw 5 is driven by the reciprocating screw sleeve 11. The sleeve plate 12 is fixedly installed on the reciprocating screw sleeve 11. The connecting piece 13 is fixedly connected to the sleeve plate 12 and the cross bar 14. The rubber ball 15 is fixedly installed at the bottom of the cross bar 14.

[0038] With the above structure, during equipment operation, the power motor 4 is started, continuously driving the reciprocating screw 5 to rotate at a uniform speed. Utilizing the special thread trajectory of the reciprocating screw 5, the rotational motion is precisely converted into the vertical linear reciprocating motion of the reciprocating screw sleeve 11. The reciprocating screw sleeve 11 drives the sleeve plate 12 to slide smoothly and vertically along the outer side of the top frame 3, and then drives the crossbar 14 to perform regular up-and-down reciprocating motion through the connecting piece 13. This causes the rubber ball 15 at the bottom of the crossbar 14 to continuously, repeatedly, and evenly strike the outer wall of the conveying pipe 1. Through the high-frequency vibration and striking action, the lithium battery micro-powder adhering, accumulating, and agglomerated on the inner wall of the conveying pipe 1 can be shaken off in real time, effectively breaking up agglomerated materials and preventing powder accumulation, bridging, and pipe blockage from the source. This ensures that the material channel inside the conveying pipe 1 is unobstructed throughout, significantly improving the continuity and overall conveying efficiency of the positive pressure conveying of lithium battery powder.

[0039] By adopting the above technical solution, the reciprocating screw 5 is driven to rotate by the power motor 4, which in turn drives the reciprocating screw sleeve 11, sleeve plate 12, and crossbar 14 to continuously and repeatedly strike the outer wall of the conveying pipe 1 with the rubber ball 15. The mechanical vibration cleans the fine lithium battery powder adhering to the pipe wall in real time, which can effectively avoid the problem of fine powder agglomeration and blockage due to moisture. There is no need for manual shutdown for unblocking, ensuring the long-term smooth operation of the conveying pipe 1. The rubber ball 15 is used as the striking part, which has flexible buffering characteristics. While effectively shaking off the powder, it will not cause hard impact damage to the pipe wall of the conveying pipe 1. It can protect the structural integrity of the conveying pipe 1, reduce the risk of pipe wear and cracking, extend the overall service life of the equipment, and reduce maintenance and replacement costs. The entire anti-blocking mechanism can achieve continuous reciprocating striking operation with only a single power motor 4. There is no need to add an additional vibration motor or unblocking auxiliary equipment. The power utilization rate is high and the overall energy consumption is low.

[0040] Specifically, the anti-clogging mixing mechanism also includes shaft 1 (6), shaft 2 (7), stirring blade (8), sealed bearing (9), pipe (10), storage tank (16), seal 1 (17), seal 2 (18), conduit (19), and discharge pipe (20). Shaft 1 (6) is fixedly installed at the bottom of the reciprocating screw 5. Stirring blade 8 is fixedly installed on the outside of shaft 2 (7). Sealed bearing 9 is installed on both shaft 1 (6) and shaft 2 (7). Pipe 10 is installed between the two sealed bearings 9. Storage tank 16 is fixedly installed on lithium battery powder tank 2. Conduit 19 is fixedly installed on storage tank 16 and pipe 10. Seals 1 (17) and 2 (18) are both slidably sealed on lithium battery powder tank 2. Seal 2 (18) is in sealing contact with conduit 19. Discharge pipe 20 is fixedly installed on shaft 2 (7).

[0041] With the above structure, when the equipment is running, the starter motor 4 drives the reciprocating screw 5 to rotate continuously, and the reciprocating screw 5 synchronously drives the shaft 6 at the bottom to rotate as well. With the support and transmission of the sealed bearing 9, the shaft 6 drives the shaft 7 to rotate synchronously, and the stirring blade 8 on the outside of the shaft 7 rotates continuously inside the lithium battery powder tank 2, stirring and mixing the accumulated and agglomerated lithium battery powder in all directions, preventing the powder from stratifying and clumping due to prolonged standing. At the same time, the reciprocating screw 5 drives the reciprocating screw sleeve 11 and the sleeve plate 12 to perform vertical reciprocating motion, and the sleeve plate 12 synchronously drives the seal 17 to slide vertically back and forth along the inner wall of the lithium battery powder tank 2. The storage tank 16, the conduit 19 and the pipe body 10 are filled with transmission hydraulic oil. The reciprocating motion of the seal 17 squeezes the hydraulic oil in the cavity, and uses hydraulic transmission power to push the seal 18 to move laterally back and forth. The sealing element 18 continuously changes the effective flow cross section of the conduit 19, causing the auxiliary powder feeding rate to alternate between fast and slow, thus achieving dynamic variable speed feeding. Different component powders are mixed in stages and at varying speeds, and with the forced stirring of the stirring blade 8, the uniformity of the various powders is further improved. Finally, the mixed powder is sent into the conveying pipe 1 through the discharge pipe 20 at the bottom of the shaft 7. Combined with the anti-clogging action of the front rubber ball 15, the entire mechanism simultaneously completes multiple operations such as powder mixing, dynamic batching, and pipeline anti-clogging.

[0042] By adopting the above technical solution, shaft 6 and shaft 7 are assembled with pipe 10 through sealed bearing 9, which not only provides stable support for the rotating shaft and reduces rotational friction resistance, making the transmission smoother, but also achieves reliable sealing of moving and stationary parts, preventing lithium battery powder from entering the transmission gap and causing jamming and wear, while avoiding internal hydraulic oil leakage and ensuring long-term stable operation of the hydraulic transmission system. Relying on the hydraulic adjustment circuit composed of seal 17, seal 18, conduit 19, and storage tank 16, the reciprocating motion of sleeve 12 is converted into hydraulic driving force, automatically controlling the reciprocating movement of seal 18, dynamically changing the flow area of ​​conduit 19, and allowing the auxiliary powder feeding speed to alternate between fast and slow. Variable speed feeding combined with forced stirring by stirring blade 8 can achieve thorough mixing of multi-component powders.

[0043] Specifically, the top of the shaft 2 7 has a round hole that is connected to the inside of the tube 10. The discharge pipe 20 is connected to the inside of the tube 10. There are multiple discharge pipes 20, and the lengths of the multiple discharge pipes 20 are all different.

[0044] Through the above structure, during operation, the auxiliary powder inside the storage tank 16 is smoothly introduced into the tube body 10 via the conduit 19, and then diverted into multiple discharge pipes 20 through the round hole at the top of the shaft body 7. Relying on the staggered arrangement of the discharge pipes 20 of varying lengths, the auxiliary powder is sprinkled and fed from multiple points at different heights and radial positions inside the lithium battery powder tank 2, breaking the problem of concentrated accumulation from traditional single-point feeding. This achieves uniform, dispersed feeding of auxiliary materials across the entire area, providing a good material distribution foundation for subsequent mixing. Simultaneously, the discharge pipes 20 are positioned above the stirring blades 8, allowing the auxiliary materials falling into the tank to diffuse and distribute in advance. Combined with the rotational disturbance of the stirring blades 8 below, this further enhances the uniformity of mixing between the main and auxiliary materials.

[0045] Specifically, a discharge pipe 21 is fixedly installed at the bottom of the lithium battery powder tank 2. The discharge pipe 21 is fixedly installed on the conveying pipe 1. A solenoid valve 22 is installed on the discharge pipe 21. A sleeve plate 12 is slidably sleeved on the outside of the top frame 3. A Roots blower 23 is fixedly installed at the end of the conveying pipe 1.

[0046] With the above structure, a Roots blower 23 is fixedly installed at the end of the conveying pipe 1 as a positive pressure pneumatic conveying power source. After the equipment completes the powder mixing process, the solenoid valve 22 is opened, and the qualified mixture in the tank falls into the conveying pipe 1 through the discharge pipe 21. The Roots blower 23 is started to generate a stable high-pressure positive pressure airflow, which uses compressed air as power to carry the powder material along the conveying pipe 1 for closed directional conveying.

[0047] Specifically, the top of the lithium battery powder tank 2 is provided with an L-shaped hole, and both the first seal 17 and the second seal 18 are slidably sealed in the L-shaped hole. The L-shaped hole is filled with hydraulic oil. The top of the storage tank 16 is fixedly provided with an addition pipe, and a threaded cap is threadedly connected to the addition pipe. The discharge pipe 20 is located above the stirring blade 8.

[0048] With the above structure, when the sleeve 12 slides vertically back and forth with the reciprocating screw sleeve 11, it can continuously push the seal 17 to slide back and forth inside the L-shaped hole. By utilizing the characteristics of hydraulic oil being incompressible and transmitting pressure stably, the vertical mechanical displacement is accurately converted into lateral thrust, thereby driving the seal 18 to move back and forth synchronously inside the L-shaped hole, accurately changing the flow cross-sectional area of ​​the guide tube 19.

[0049] Working principle: During equipment operation, the operator unscrews the threaded cap on top of the storage tank 16 and adds various auxiliary powders required for the specified proportions into the storage tank 16 through the adding pipe. After adding, the threaded cap is tightened to ensure the cavity is sealed. The auxiliary powder inside the storage tank 16 flows smoothly into the pipe body 10 along the guide tube 19 under its own weight. Then, it is distributed through the round hole at the top of the shaft 7. The powder enters the discharge pipes 20 of different lengths and specifications in sequence. With the help of the staggered discharge pipe openings, the auxiliary materials are evenly sprinkled into the internal cavity of the lithium battery powder tank 2 from multiple directions, achieving full-area feeding without dead corners and avoiding the accumulation of auxiliary materials.

[0050] The power motor 4, fixedly installed above the top frame 3, is started. The output shaft of the power motor 4 drives the reciprocating screw 5 to maintain a uniform rotational motion. During the operation of the reciprocating screw 5, the shaft 6 fixed at its lower end rotates synchronously. Under the rotational support and transmission cooperation of the sealed bearing 9, it drives the shaft 7 to rotate synchronously. The stirring blade 8 fixed on the outside of the shaft 7 continuously stirs the material in the tank, fully mixing and stirring the lithium battery main material powder with the added auxiliary powder, effectively breaking up the agglomerated material particles, and ensuring that the material texture is loose and uniform. At the same time, the rotating reciprocating screw 5 and the reciprocating screw sleeve 11 form a threaded transmission cooperation, converting the rotary motion into linear reciprocating motion, driving the fixedly connected sleeve plate 12 to slide stably back and forth along the vertical guide rail structure on the outside of the top frame 3.

[0051] During the vertical reciprocating movement of the sleeve 12, it simultaneously pushes the sealing element 17 to slide vertically within the L-shaped hole at the top of the lithium battery powder tank 2. Pressure is transmitted via the hydraulic oil filling the cavity, which in turn drives the sealing element 18 to slide laterally within the hole. The sealing element 18 blocks the cross-section of the guide tube 19, intermittently regulating the flow rate of the auxiliary material, thus matching the feeding speed with the internal mixing rhythm and further improving the overall material mixing accuracy. As the sleeve 12 moves, it also drives the horizontal bar 14 to rise and fall synchronously via the connecting piece 13. The rubber ball 15 mounted at the bottom of the horizontal bar 14 then rhythmically and repeatedly strikes the outer wall of the conveying pipe 1, using vibration to dislodge powder material adhering to the inner wall of the pipe, breaking up accumulated blockages, preventing blockages in the conveying pipeline at the source, and ensuring smooth material flow.

[0052] Once the materials inside the lithium battery powder tank 2 are fully mixed to the required standard, the operator opens the solenoid valve 22 installed on the discharge pipe 21. The mixed powder material then smoothly falls from the tank through the discharge pipe 21 into the cavity of the conveying pipe 1. The Roots blower 23 at the end of the conveying pipe 1 is then started. The blower generates a stable, high-pressure positive airflow, using compressed air as the conveying power to carry the powder material along the internal channel of the conveying pipe 1 in a directional and stable manner. The entire material transfer operation is completed within a closed pipeline. This device integrates uniform feeding, dynamic speed-adjustable mixing, vibration anti-clogging, and positive pressure pneumatic conveying functions into one unit. All structures operate in a coordinated and interconnected manner, resulting in a smooth and compact workflow that can stably and efficiently complete the continuous conveying and processing of lithium battery powder.

[0053] The above provides a detailed description of a lithium battery positive pressure pneumatic conveying device.

These embodiments are merely illustrative and are intended to help understand the method and core concepts of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
