Description

Technical Field

[0001] This invention relates to the field of high-viscosity material dispersion equipment, specifically a dual planetary dispersion feeder. Background Technology

[0002] The dual planetary disperser feeder evolved from the traditional dual planetary mixer. It is specifically designed for continuous production lines and is used to process slurries with high viscosity and high solids content.

[0003] These slurries include lithium battery electrode slurries, photovoltaic silver pastes, and specialty coatings. Their function is to efficiently disperse and mix the slurries, while also ensuring a stable and continuous supply of materials to downstream processes, and the supplied materials must have a uniform composition.

[0004] The main component of the dual planetary disperser is a movable material hopper with an integrated drive system above it. This system simultaneously drives the central stirring paddle and two symmetrical dispersing shafts. These components perform compound movements. The purpose of this equipment is to achieve integrated mixing, dispersing, and feeding.

[0005] In terms of specific device structure, existing technologies have typical designs, such as the design shown in authorized patent CN 202070307 U. It mainly includes a fixed or lifting body, on which a dual-motor drive mechanism is mounted. It also includes a planetary gearbox, a central stirring shaft, and two dispersing shafts on either side. Multiple dispersing discs are fixedly mounted on the dispersing shafts, typically two discs.

[0006] Its operation is as follows: One motor drives the planetary gearbox to revolve. Simultaneously, an internal gear system drives the dispersion shaft to rotate. Another independent motor drives the central stirring shaft to rotate. The material container can be moved in and out via guide rails or a lifting mechanism.

[0007] However, in this classic structure, all the dispersion disks are rigidly fixed. Their spacing is not adjustable. Once installed, the shear field intensity distribution formed within the hopper is fixed, and its flow field structure is static and immutable.

[0008] This fixed-spacing structure leads to several key technical problems. First, the equipment cannot be adjusted according to different processing stages of the material, including wetting, coarse dispersion, and fine dispersion. It also cannot adapt to the differences in rheological properties of different formulations, and cannot dynamically adjust the shear strength and range of action.

[0009] Secondly, it easily creates mixing dead zones and axial stratification. Fixed multi-layered discs form stable laminar shear zones. Material circulates between layers, but vertical convection is weak. For materials that easily settle, this makes it difficult to ensure the uniformity of composition across the longitudinal section of the hopper. This affects the quality stability of continuous feeding.

[0010] Furthermore, the equipment cannot optimize in real time based on online monitoring data, including material viscosity or torque, which may lead to energy waste under inefficient operating conditions or excessive shear heating of heat-sensitive materials.

[0011] Therefore, we propose a dual planetary dispersion feeder to address the problems mentioned above. Summary of the Invention

[0012] This invention provides a dual planetary dispersing feeder, which can solve the problem that all dispersing discs in the existing dispersing feeder are rigidly fixed, which easily leads to mixing dead zones and axial delamination.

[0013] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A dual planetary dispersion feeder includes a material hopper, a movable base at the bottom of the material hopper, a support frame between the bottom of the material hopper and the movable base for stable support of the material hopper, a hopper cover at the top of the material hopper, a planetary gear box inside the hopper cover, a planetary gear transmission mechanism installed inside the planetary gear box, two planetary shafts on the side of the hopper cover near the material hopper, the planetary gear transmission mechanism driving the two planetary shafts to rotate and revolve, and a dispersion shaft fixedly installed on the side of the planetary shafts near the inside of the material hopper; The dispersing shaft is provided with a coarse shearing disc, a medium shearing disc, and a fine shearing disc from top to bottom. The dispersing shaft is a hollow rod with a hydraulic telescopic rod installed inside. The inner telescopic rod of the hydraulic telescopic rod is tightly slidably engaged with the inside of the dispersing shaft. A sliding groove is provided on one side of the dispersing shaft. A sliding block is fixedly installed on the inner telescopic rod of the hydraulic telescopic rod. The sliding block is slidably connected inside the sliding groove. The medium shearing disc is slidably sleeved on the outside of the dispersing shaft and fixedly connected to the sliding block.

[0014] Preferably, the planetary gear transmission mechanism includes a planet carrier, a main shaft is provided on the upper part of the planet carrier, the main shaft is rotatably connected to the planetary gear box, and a bearing disk is installed between the outside of the main shaft and the planetary gear box, and a central shaft is rotatably sleeved inside the main shaft.

[0015] Preferably, a reduction motor is fixedly installed at the middle of the upper end of the bucket lid, the shaft of the reduction motor is fixedly connected to the central shaft, and a central gear is fixedly installed at the end of the central shaft away from the reduction motor.

[0016] Preferably, a gear ring is fixedly installed inside the planetary gearbox, and the gear ring is coaxially arranged with the central gear.

[0017] Preferably, the two planetary shafts are installed at opposite ends of the planet carrier, and each planetary shaft is equipped with a planetary gear that meshes between the gear ring and the central gear.

[0018] Preferably, the central shaft passes through the interior of the central gear, and an installation groove is provided inside the end of the central shaft away from the reduction motor. A stirring motor is installed inside the installation groove, and a stirring paddle is installed on the rotating shaft of the stirring motor.

[0019] Preferably, a multi-channel rotary slip ring is installed between the geared motor and the central shaft. The multi-channel rotary slip ring is used to supply power to the stirring motor and to deliver oil to the hydraulic telescopic rod.

[0020] Preferably, the bottom of the material bin is provided with an arc-shaped bottom, and an electromagnetic switch valve is installed at the center of the arc-shaped bottom, with a feeding pipe fixedly connected to the electromagnetic switch valve.

[0021] Preferably, the movable base includes a flat plate, casters mounted on the bottom of the flat plate, and a push handle mounted on one end of the flat plate. A feeding pump is mounted on the flat plate, the feed inlet of the feeding pump is fixedly connected to the feeding pipe, and a feeding connector is fixedly connected to the upper side of the material bucket. The feeding connector is provided with multiple interfaces.

[0022] Preferably, the diameters of the coarse shearing disc, the medium shearing disc, and the fine shearing disc decrease sequentially from top to bottom, and the tooth density of the shearing teeth on their disc edges increases sequentially from top to bottom.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are: I. This invention, a dual planetary dispersing feeder, utilizes a hydraulic telescopic rod installed inside the dispersing shaft during its compound motion. This rod drives the telescopic inner rod up and down, causing the middle shear disc, fixed to the sliding block, to rise and fall between the coarse and fine shear discs. This dynamically adjusts the spacing of the shearing layers, fundamentally solving the process rigidity problem caused by the fixed dispersing discs in existing technologies. This equipment can dynamically adjust the shear disc spacing in real-time and online according to the different stages of material dispersing from wetting to fine dispersion, automatically matching the shearing intensity required by different formulations and processes. Simultaneously, the periodic up-and-down movement of the middle shear disc actively disrupts the originally stable laminar flow field, greatly enhancing the forced convection of materials in the axial direction. This effectively eliminates mixing dead zones and vertical stratification, ensuring absolute uniformity of material from the top to the bottom of the hopper, thus guaranteeing excellent stability in continuous feeding quality.

[0024] Second, this invention detects viscosity signals using speed and torque sensors on the geared motor and stirring motor. The system can automatically optimize the position and operating parameters of the shear discs, avoiding energy waste under inefficient operating conditions. This also prevents excessive shearing and heating of heat-sensitive materials. Furthermore, the diameter and tooth density of the three shear discs are gradient-distributed, achieving precise graded utilization of energy. The multi-channel rotating slip ring ensures stable transmission of electricity and hydraulic pressure, the arc-shaped barrel bottom ensures residue-free material discharge, and the integrated mobile feeding base design allows for flexible equipment deployment. Ultimately, this equipment achieves ultra-uniform dispersion and mixing. It also enables more economical and controllable continuous feeding and can adapt to the needs of flexible production.

[0027] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0028] Example 1: Please see Figure 1-5 The present invention provides a technical solution: A dual planetary dispersion feeder includes a material hopper 1, a movable base 2 at the bottom of the material hopper 1, a support frame 3 between the bottom of the material hopper 1 and the movable base 2 for stable support of the material hopper 1, a hopper cover 4 at the top of the material hopper 1, a planetary gear box 5 inside the hopper cover 4, a planetary gear transmission mechanism installed inside the planetary gear box 5, two planetary shafts 10 on the side of the hopper cover 4 near the material hopper 1, the planetary gear transmission mechanism drives the two planetary shafts 10 to rotate and revolve, and a dispersion shaft 17 is fixedly installed on the side of the planetary shafts 10 near the inside of the material hopper 1. The dispersing shaft 17 is provided with a coarse shearing disc 18, a medium shearing disc 19, and a fine shearing disc 20 arranged sequentially from top to bottom. The dispersing shaft 17 is a hollow rod with a hydraulic telescopic rod 21 installed inside. The telescopic inner rod of the hydraulic telescopic rod 21 is tightly slidably engaged with the inside of the dispersing shaft 17. A sliding groove 22 is provided on one side of the dispersing shaft 17. A sliding block 23 is fixedly installed on the telescopic inner rod of the hydraulic telescopic rod 21. The sliding block 23 is slidably connected inside the sliding groove 22. The medium shearing disc 19 is slidably sleeved on the outside of the dispersing shaft 17 and fixedly connected to the sliding block 23.

[0029] In the above design, the dispersing shaft 17 is designed as a hollow rod, with a hydraulic telescopic rod 21 installed inside. The inner telescopic rod of the hydraulic telescopic rod 21 is connected to the intermediate shear plate 19 via a sliding block 23. During operation, the hydraulic system can drive the inner telescopic rod to move up and down within the dispersing shaft 17, thereby causing the intermediate shear plate 19 to rise and fall between the coarse shear plate 18 and the fine shear plate 20. This action enables online and dynamic adjustment of the shear plate spacing.

[0030] Firstly, it solves the problem of poor process flexibility, enabling the equipment to automatically match the optimal shear strength and range of action according to the different stages of material from wetting to fine dispersion, or the characteristics of different formulations. Secondly, the up-and-down movement of the middle shear disc 19 actively breaks the stable laminar flow zone formed by the fixed disc, forcing the material to generate strong axial convection, thereby eliminating mixing dead zones and axial stratification, ensuring the uniformity of material from the top to the bottom of the hopper, and improving the stability of the feeding quality. At the same time, this structure allows for optimization of the working state based on real-time monitored torque or viscosity signals, avoiding energy waste under inefficient operating conditions, and preventing excessive shearing and heating of heat-sensitive materials, achieving a more economical and controllable dispersion feeding process.

[0031] In some specific embodiments, the planetary gear transmission mechanism includes a planet carrier 6, with a main shaft mounted on top of the planet carrier 6. The main shaft is rotatably connected to the planetary gearbox 5, and a bearing disk 9 is installed between the main shaft and the planetary gearbox 5. A central shaft 12 is rotatably sleeved inside the main shaft. The planet carrier 6 provides overall support for the central gear 13 and planetary gears 11. The main shaft on the planet carrier 6 is rotatably connected to the planetary gearbox 5 via the bearing disk 9, ensuring smooth operation. The central shaft 12 is independently rotatably sleeved inside the main shaft, forming a coaxial nested structure. This design allows the main shaft to drive the entire mechanism to revolve, while the central shaft 12 can independently transmit stirring power, thus facilitating the subsequent dual-power compound motion.

[0032] In some specific implementations, a geared motor 8 is fixedly installed at the middle of the upper end of the bucket lid 4. The shaft of the geared motor 8 is fixedly connected to the central shaft 12. A central gear 13 is fixedly installed at the end of the central shaft 12 away from the geared motor 8. The geared motor 8 is fixedly installed on the upper end of the bucket lid 4, and its output shaft is directly connected to the central shaft 12. A speed and torque sensor is installed on the shaft of the geared motor 8. The geared motor 8 and the speed and torque sensor work together to adjust the speed and torque of the central shaft 12. The central gear 13 installed at the end of the central shaft 12 serves as the sun gear input of the entire planetary gear system, transmitting power to the subsequent gear train, ensuring a stable and adjustable power source for the central stirring system.

[0033] In some specific embodiments, a gear ring 14 is fixedly installed inside the planetary gearbox 5. The gear ring 14 is coaxially arranged with the central gear 13. The gear ring 14 is fixedly installed inside the planetary gearbox 5 and remains coaxial with the central gear 13. This fixed gear ring 14, as an internal gear, cooperates with the rotating central gear 13 to jointly form the spatial frame of the planetary transmission. The presence of the fixed gear ring 14 forces the planetary gears 11 to generate a revolution motion while rotating on their own axis, which is key to realizing the planetary compound motion.

[0034] In some specific embodiments, two planetary shafts 10 are respectively mounted at both ends of the planet carrier 6. Each planetary shaft 10 is equipped with a planetary gear 11, which meshes between a gear ring 14 and a central gear 13. The two planetary shafts 10 are mounted at both ends of the planet carrier 6, and the planetary gear 11 on each planetary shaft 10 simultaneously meshes with both the central gear 13 and the fixed gear ring 14. When the central gear 13 rotates, it drives the planetary gear 11 to rotate. Since the other side of the planetary gear 11 meshes with the fixed gear ring 14, this meshing relationship forces the planetary gear 11 to roll along the gear ring 14, thereby driving the planet carrier 6 and the planetary shafts 10 to revolve around the central axis 12. Through this gear meshing relationship, the combined motion of the planetary shafts 10's rotation and revolution is ultimately achieved.

[0035] In some specific embodiments, the central shaft 12 passes through the interior of the central gear 13, and a mounting groove is formed inside the end of the central shaft 12 away from the reduction motor 8. A stirring motor 15 is installed inside the mounting groove, and a stirring paddle 16 is mounted on the shaft of the stirring motor 15. The central shaft 12 extends through the interior of the central gear 13, and its end has a mounting groove for installing the stirring motor 15. The shaft of the stirring motor 15 directly drives the stirring paddle 16 to rotate. This compact design, which integrates the stirring motor 15 into the end of the central shaft 12, achieves independent power transmission of the stirring system, making the rotation of the stirring paddle 16 completely independent of the revolution of the planetary gearbox 5. This allows for independent control of its speed and direction, enabling more flexible stirring operations.

[0036] Example 2: Please see Figure 1-5 Furthermore, in conjunction with Embodiment 1, a multi-channel rotary slip ring 7 is installed between the geared motor 8 and the central shaft 12. The multi-channel rotary slip ring 7 supplies power to the stirring motor 15 and delivers hydraulic fluid to the hydraulic telescopic rod 21. Installed between the geared motor 8 and the central shaft 12, its function is to provide a continuous power supply to the built-in stirring motor 15 while simultaneously supplying pressurized oil to the hydraulic telescopic rod 21 inside the dispersing shaft 17. This design ensures stable and continuous transmission of electricity and hydraulic fluid during continuous operation of the equipment, thereby supporting the normal operation of the stirring and dynamic adjustment functions.

[0037] In some specific implementations, the material bin 1 has an arc-shaped bottom, with an electromagnetic switch valve installed at the center of the arc-shaped bottom. A feed pipe 25 is fixedly connected to the electromagnetic switch valve. The arc-shaped bottom structure of the material bin 1, with the electromagnetic switch valve and feed pipe 25 installed at the center, facilitates residue-free material discharge. The arc-shaped bottom guides the material to naturally converge towards the center. The electromagnetic switch valve can quickly control the opening and closing of the discharge port, while the feed pipe 25 serves as a fixed channel for material flow, jointly ensuring a smooth and controllable feeding process.

[0038] In some specific implementations, the mobile base 2 includes a flat plate, casters mounted on the bottom of the flat plate, and a push handle mounted on one end of the flat plate. A feed pump 26 is mounted on the flat plate, with its inlet fixedly connected to a feed pipe 25. A feed connector 27 is fixedly connected to the upper side of the material tank 1, and the feed connector 27 has multiple interfaces. The mobile base 2 enables the equipment to move easily. The feed pump 26, mounted on the flat plate, has its inlet connected to a solenoid valve at the bottom of the material tank 1 via the feed pipe 25, responsible for pumping out the processed slurry from the tank. Simultaneously, the multiple feed connectors 27 at the upper end of the material tank 1 facilitate the connection of pipelines for different raw materials. This system has movement, feeding, and discharging functions, allowing the feeder to be flexibly arranged and integrated into the production line.

[0039] In some specific implementations, the diameters of the coarse shear disc 18, the medium shear disc 19, and the fine shear disc 20 decrease sequentially from top to bottom, while the tooth density of their edge shearing teeth increases sequentially from top to bottom. This stepped structural design, with its progressively decreasing diameter and increasing edge shearing tooth density, creates a gradually changing shear intensity field in the axial direction. The upper coarse shear disc 18 is primarily responsible for the initial crushing of large particles, while the lower fine shear disc 20 performs fine homogenization and dispersion. This structure optimizes energy distribution during the dispersion process, achieving a step-by-step dispersion effect from coarse to fine, thus improving overall dispersion efficiency.

[0040] The working principle of this dual planetary dispersing feeder is as follows: When the equipment is working, the reduction motor 8 drives the central shaft 12 to rotate, and the central gear 13 installed at the end of the central shaft 12 rotates accordingly. The central gear 13 drives the two planetary shafts 10 to rotate by meshing with the planetary gears 11; at the same time, since the planetary gears 11 also mesh with the gear ring 14 fixed inside the planetary gearbox 5, the planetary gears 11 are forced to drive the planetary carrier 6 and the planetary shafts 10 to revolve around the central shaft 12. In this way, the dispersing shaft 17 fixed at the end of the planetary shafts 10 obtains a combined motion of rotation and revolution.

[0041] Meanwhile, another independent stirring motor 15 directly drives the stirring paddle 16 to rotate, achieving independent stirring action. During the compound motion of the dispersion shaft 17, the hydraulic telescopic rod 21 installed inside it can receive pressure oil delivered from the multi-channel rotating slip ring 7, driving the telescopic inner rod to move up and down, thereby causing the middle shear plate 19, which is fixed to the sliding block 23, to rise and fall between the coarse shear plate 18 and the fine shear plate 20, dynamically adjusting the spacing of the shearing layers.

[0042] The material undergoes a gradient shearing process, from coarse to fine shearing, through a dispersion disc assembly with decreasing diameter and increasing tooth density. The processed material is guided by the arc-shaped bottom of the drum and pumped out by the feed pump 26 through the feed pipe 25. The entire equipment is supported by a movable base 2 with casters, facilitating movement and positioning.

[0043] The design of the liftable central shear disc 19 breaks the fixed flow field, enhances axial mixing, and eliminates stratification and dead zones. The dynamic adjustment capability of the spacing allows the equipment to adapt to different process stages and material formulations, improving process flexibility. Simultaneously, optimized control of shear intensity based on real-time monitoring signals avoids energy waste and material overheating. This system possesses mixing, dispersing, and conveying functions, achieving continuous, stable, and controllable material supply.

[0044] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
