Description

Technical Field

[0001] This invention belongs to the field of transportation equipment technology, and specifically relates to a transmission device for a high-solids alumina mixture. Background Technology

[0002] High-solids alumina mixtures are suspensions or slurries with a high volume or mass fraction of alumina particles. They have significant application value in high-end manufacturing fields such as new energy battery substrates and precision ceramics. Their transport stability directly affects the microstructure forming quality of high-density ceramics / composite materials. Due to their extremely high solids content, these mixtures are prone to particle sedimentation and tank wall scaling during transportation. Improper control can lead to material stratification, performance degradation, and even pipeline solidification and scrapping.

[0003] Various solutions have been developed for the transfer of high-solids alumina mixtures, including insulation structures and stirring systems. However, existing equipment is prone to creating flow dead zones and stirring blind zones when transferring high-viscosity, high-solids alumina mixtures, leading to problems such as particle settling and tank wall scaling during the transfer process.

[0004] Therefore, it is necessary to study a high-solid-phase alumina mixture that can stir the mixture by axial flow and low-speed scraper to avoid crystal damage while preventing the formation of low-speed flow dead zones and stirring dead angles, and prevent tank wall scaling and deposition by using wall vibration technology.

The switching component is fixedly connected to the end of the outer shaft away from the vibration component. The first motor is connected to the inner shaft. The central shaft is fixedly connected to the inner shaft via a switching component to achieve synchronous rotation of the central and inner shafts, and the fixed connection between the central shaft and the switching component locks the inner shaft. The stirring mechanism includes a scraper, a stirring shaft, and blades. The scraper is connected to a vibration assembly and fits against the inner wall of the inner tank. The stirring shaft is fixedly connected to an inner shaft, and blades are provided on the inner shaft.

[0007] Furthermore, the connecting mechanism includes an inner flange, a guide rod, a spring, and an outer flange. The inner flange is fixedly connected to the outer wall of the inner tank, and the outer flange is fixedly connected to the inner wall of the outer tank. A guide rod is provided on the inner flange, and the guide rod is slidably engaged with the outer flange. The spring is arranged around the guide rod, and both ends of the spring are connected to the inner flange and the outer flange, respectively.

[0008] Furthermore, the switching assembly includes a bracket, a lead screw, a sliding plate, a sliding sleeve, and a second motor. The bracket is fixedly connected to the outer shaft, the lead screw is rotatably mounted on the bracket, the second motor is connected to the lead screw, the sliding sleeve is slidably mounted on the inner shaft, the sliding sleeve is slidably mounted on the bracket, the sliding plate cooperates with the lead screw, and the sliding sleeve is rotatably mounted on the sliding plate.

[0009] Furthermore, the outer wall of the central shaft near the switching component is provided with external teeth, and the inner wall of the sliding sleeve is provided with internal teeth, with the external teeth cooperating with the internal teeth.

[0010] Furthermore, the bracket is provided with a first connecting tooth, and the sliding sleeve is provided with a second connecting tooth that meshes with the first connecting tooth on the side near the storage tank.

[0011] Furthermore, the inner shaft is provided with a third connecting tooth at the end away from the storage tank, and the sliding sleeve is provided with a fourth connecting tooth that mates with the third connecting tooth on the side away from the storage tank.

[0012] Furthermore, the vibration assembly includes a housing, a balance wheel, and a connecting flange.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention discloses a high-solids alumina mixture transfer device. Through the mechanical linkage of the scraper and the vibration component, while the scraper rotates at low speed to scrape off the scale layer on the inner tank wall, it drives the inner tank to vibrate slightly. This allows the alumina particles attached to the tank wall to be efficiently peeled off under the combined action of shear force and inertial force. Combined with the spring energy storage and release mechanism of the connecting mechanism, the radial force of the scraper is converted into the axial vibration energy of the inner tank as a whole. This effectively eliminates the deposition blind spots on the curved surface and corners of the inner tank, and solves the scaling and sedimentation problems in the transfer of high-solids alumina mixture from the root.

[0017] 2. The present invention discloses a high-solids alumina mixture transfer device, which is based on the combination of axial flow blades and low-speed scrapers to achieve comprehensive stirring while avoiding damage to the crystal structure. The axial flow generated by the axial flow blades effectively eliminates the dead zone of flow, while the periodic oscillation of the scraper enhances the material exchange in the near-wall area. Furthermore, the switching component can lock the central axis, which not only protects the alumina crystals from high-speed shearing damage, but also ensures the structural stability of the equipment under complex working conditions, significantly improving the reliability of transmission.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0022] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0023] Please see Figures 1 to 7 As shown, a transfer device for a high-solids alumina mixture includes: A transfer device for a high-solids alumina mixture includes: a storage tank 1 for storing and transferring the high-solids alumina mixture; a connecting mechanism 2 for dynamically connecting an outer tank 11 and an inner tank 12; a driving mechanism 3 for driving a stirring mechanism 4; and a stirring mechanism 4 for stirring the high-solids alumina mixture and driving the inner tank 12 to vibrate within the outer tank 11.

[0024] The storage tank 1 includes an outer tank 11 and an inner tank 12. The inner tank 12 is installed inside the outer tank 11 via a connecting mechanism 2. Sliding grooves 111 are provided on the inner walls at both ends of the outer tank 11. Connecting pipes 122 are provided at both ends of the inner tank 12, and these connecting pipes 122 are slidably disposed within the sliding grooves 111. This means that the connecting pipes 122 can slide within the sliding grooves 111. Preferably, the gap between the outer tank 11 and the inner tank 12 is evacuated using a vacuum device to enhance the insulation effect of the storage tank 1.

[0025] Preferably, the inner tank 12 is provided with an anti-corrosion layer 121. In this embodiment, the anti-corrosion layer 121 is an alumina ceramic liner or a silicon carbide ceramic coating.

[0026] The connecting mechanism 2 includes an inner flange 21, a guide rod 211, a spring 22, and an outer flange 23. The inner flange 21 is fixedly connected to the outer wall of the inner tank 12, and the outer flange 23 is fixedly connected to the inner wall of the outer tank 11. The guide rod 211 is provided on the inner flange 21, and the guide rod 211 is slidably engaged with the outer flange 23. The spring 22 is arranged around the guide rod 211, and its two ends are respectively connected to the inner flange 21 and the outer flange 23. It can be understood that when the scraper 41 is working, the radial force of the scraper 41 acts on the inner wall of the inner tank 12, specifically on the anti-corrosion layer 121, driving the inner tank 12 to slide in the radial direction. During this process, the connecting pipe 122 slides back and forth in the groove 111 of the outer tank 11. The spring 22 of the connecting mechanism 2 is compressed and released by the relative displacement of the inner flange 21 and the outer flange 23, thereby forming a slight axial vibration of the inner tank 12 relative to the outer tank 11.

[0027] Specifically, the outer tank 11 is provided with a first inlet pipe 112, and the inner tank 12 is provided with a second inlet pipe 123. The first inlet pipe 112 and the second inlet pipe 123 are connected by a flexible connecting pipe 13. This means that the stirring mechanism 4 can operate normally during the feeding and discharging processes, preventing particle sedimentation and scaling on the tank wall of the high-solids alumina mixture during feeding and discharging. In particular, it prevents the stirring mechanism 4 from malfunctioning during feeding, which could lead to severe particle sedimentation and scaling on the tank wall, preventing the high-solids alumina mixture from becoming unusable after feeding.

[0028] The drive mechanism 3 includes a vibration assembly, an outer shaft 32, a central shaft 33, an inner shaft 34, a switching assembly, and a first motor 36. The outer shaft 32 is fixedly connected to the outer tank 11, with one end extending through the outer tank 11 and a connecting pipe 122 into the inner tank 12. A gap exists between the outer shaft 32 and the inner wall of the connecting pipe 122. This gap effectively prevents the connecting pipe 122 from colliding with the outer shaft 32 during slight axial vibrations of the inner tank 12, thus preventing damage to the equipment. The vibration assembly is fixedly mounted on the outer shaft 32, and the central shaft 33 is rotatably mounted within the outer shaft 32, cooperating with the vibration assembly. The central shaft 33 is fixedly connected to the inner shaft 34 via the switching assembly, enabling synchronous rotation of the central shaft 33 and the inner shaft 34. The fixed connection between the central shaft 33 and the switching assembly locks the inner shaft 34.

[0029] Specifically, the vibration assembly includes a housing 311, a balance wheel 312, and a connecting flange 313. The housing 311 is fixedly connected to the outer shaft 32. The balance wheel 312 is disposed within the housing 311. The cross-sectional profiles of the balance wheel 312 and the housing 311 are equidistant lines of a pair of conjugate incycloids. The connecting flange 313 is provided on the balance wheel 312 and is connected to the scraper 41. Correspondingly, a cam 331 is provided on the central shaft 33, and the cam 331 slides in engagement with the balance wheel 312.

[0030] This can be understood as follows: the rotation of the central shaft 33 drives the cam 331 to rotate synchronously. The cam 331 and the swing wheel 312 are pressed together, driving the swing wheel 312 to periodically deflect and swing around the axis of the outer shaft 32 while rotating. This, in turn, drives the scraper 41 to periodically deflect and swing around the axis of the outer shaft 32 while rotating through the connecting flange 313. This allows the scraper 41 to scrape away the alumina scale adhering to the inner wall while rotating. At the same time, it works with the inner tank 12 to drive the inner tank 12 to vibrate slightly, preventing the occurrence of low-speed flow dead zones and stirring dead angles, and effectively preventing the particle sedimentation of alumina and the scaling of the tank wall on the inner wall of the inner tank 12.

[0031] The inner shaft 34 is rotatably mounted in the central shaft 33. One end of the inner shaft 34 extends through the vibration assembly into the inner tank 12. The switching assembly is fixedly connected to the end of the outer shaft 32 away from the vibration assembly. The first motor 36 is connected to the inner shaft 34.

[0032] Specifically, the switching assembly includes a bracket 351, a lead screw 353, a sliding plate 354, a sliding sleeve 355, and a second motor 37. The bracket 351 is fixedly connected to the outer shaft 32. The lead screw 353 is rotatably mounted on the bracket 351. The second motor 37 is connected to the lead screw 353. The sliding sleeve 355 is slidably mounted on the inner shaft 34 and the bracket 351. The sliding plate 354 cooperates with the lead screw 353, and the sliding sleeve 355 is rotatably mounted on the sliding plate 354. In essence, the second motor 37 drives the lead screw 353 to rotate, causing the sliding plate 354 to reciprocate along the lead screw 353, thereby driving the sliding sleeve 355 to reciprocate along the central shaft 33 without affecting its rotation.

[0033] Specifically, the outer wall of the central shaft 33 near the switching component is provided with external teeth 332, and the inner wall of the sliding sleeve 355 is provided with internal teeth 356. The external teeth 332 and the internal teeth 356 engage. It can be understood that the central shaft 33 drives the sliding sleeve 355 to rotate synchronously through the meshing of the external teeth 332 and the internal teeth 356.

[0034] Specifically, the bracket 351 is provided with a first connecting tooth 352, and the sliding sleeve 355 is provided with a second connecting tooth 357 that meshes with the first connecting tooth 352 on the side near the storage tank 1. This can be understood as follows: when the second motor 37 drives the sliding sleeve 355 to slide towards the storage tank 1 via the lead screw 353 and the sliding plate 354, until the first connecting tooth 352 meshes with the second connecting tooth 357, the central shaft 33 is connected to the bracket 351 via the sliding sleeve 355. At this time, the central shaft 33 cannot rotate, thus locking the central shaft 33.

[0035] Specifically, the inner shaft 34 is provided with a third connecting tooth 341 at the end away from the storage tank 1, and the sliding sleeve 355 is provided with a fourth connecting tooth 358 that engages with the third connecting tooth 341 on the side away from the storage tank 1. This can be understood as follows: when the second motor 37 drives the sliding sleeve 355 to slide away from the storage tank 1 via the lead screw 353 and the sliding plate 354, until the third connecting tooth 341 and the fourth connecting tooth 358 mesh, the central shaft 33 is connected to the inner shaft 34 via the sliding sleeve 355, at which point the central shaft 33 and the inner shaft 34 rotate synchronously.

[0036] The stirring mechanism 4 includes a scraper 41, a stirring shaft 42, and a paddle 421. The scraper 41 is connected to a vibration assembly and fits against the inner wall of the inner tank 12. The stirring shaft 42 is fixedly connected to an inner shaft 34, and the paddle 421 is mounted on the inner shaft 34. Specifically, the paddle 421 is an axial flow paddle. The rotation of the paddle 421 can drive the high-solid-phase alumina mixture to flow axially, effectively preventing the occurrence of low-speed flow dead zones and stirring dead angles.

[0037] It should be noted that there is a gap between the blade 421 and the scraper 41, and the blade 421 will not collide with the scraper 41 when the scraper 41 is periodically deflected and oscillated.

[0038] The working principle of this invention is as follows: During the transfer of the high solid phase alumina mixture, the first motor 36 drives the inner shaft 34 to rotate, and the inner shaft 34 drives the blade 421 to rotate through the stirring shaft 42. The blade 421 stirs the high solid phase alumina mixture in the inner tank 12. The second motor 37 of the switching component rotates. The second motor 37 drives the sliding sleeve 355 to slide away from the storage tank 1 through the lead screw 353 and the sliding plate 354. After the third connecting tooth 341 and the fourth connecting tooth 358 mesh, the central shaft 33 is connected to the inner shaft 34 through the sliding sleeve 355. At this time, the central shaft 33 and the inner shaft 34 rotate synchronously. The rotation of the central shaft 33 drives the cam 331 to rotate synchronously. The cam 331 and the swing wheel 312 are pressed together, driving the swing wheel 312 to periodically deflect and swing around the axis of the outer shaft 32 while rotating. This drives the scraper 41 to periodically deflect and swing around the axis of the outer shaft 32 while rotating through the connecting flange 313. This allows the scraper 41 to scrape away the alumina scale adhering to the inner wall while rotating. At the same time, it works with the inner tank 12 to drive the inner tank 12 to vibrate slightly, preventing the occurrence of low-speed flow dead zones and stirring dead angles. This effectively prevents the alumina particles from settling and the tank wall from forming scale on the inner wall of the inner tank 12.

[0039] When passing through bumpy sections, the first motor 36 drives the inner shaft 34 to rotate, and the inner shaft 34 drives the blades 421 to rotate through the stirring shaft 42. The blades 421 stir the high solid phase alumina mixture in the inner tank 12. The second motor 37 of the switching component rotates in the opposite direction. The second motor 37 drives the sliding sleeve 355 to slide towards the storage tank 1 through the lead screw 353 and the sliding plate 354. After the first connecting tooth 352 and the second connecting tooth 357 are engaged, the central shaft 33 is connected to the bracket 351 through the sliding sleeve 355. At this time, the central shaft 33 cannot rotate, thus locking the central shaft 33. At this time, the scraper 41 no longer rotates. Because the scraper 41 and the inner tank 12 are squeezed together, the relative sliding between the inner tank 12 and the outer tank 11 is restricted, preventing the equipment from being damaged by impact force during the transmission of high solid phase alumina mixture on bumpy road sections.
