Description

Technical Field

[0001] This disclosure relates to the field of battery material drying technology, and in particular to an electrode material drying apparatus. Background Technology

[0002] With the development of clean energy, the demand for batteries, as key components for energy storage and conversion, is exploding. Whether it's the power batteries for electric vehicles or the energy storage batteries used in energy storage systems, battery performance is crucial. Electrode material drying plays a vital role in the battery production process. The performance of battery cathode materials determines the battery's energy density and cycle life, and the drying process is a key step in the production of battery cathode materials. Currently, spray drying technology is widely used for drying battery cathode materials due to its high drying efficiency and uniform particle size. However, existing spray drying devices always spray material at a fixed angle, making it difficult to flexibly adjust the spray direction according to actual needs. This results in uneven drying, poor drying efficiency, and is not conducive to meeting the production requirements for high-quality cathode materials. Utility Model Content

[0036] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0037] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0038] The electrode material drying device in this embodiment is as follows: Figures 1-3 As shown, it includes a tower body 1, an atomizer 2, a drive assembly 3, an angle adjustment assembly 4, and a drying air assembly 5. The bottom of the tower body 1 has a material outlet 10, through which the dried material is uniformly discharged. In this embodiment, the material refers to battery positive electrode material. The atomizer 2 is fixedly installed inside the tower body 1 and is used to spray the material. The atomizer 2 in this embodiment is an existing device in the field, capable of atomizing wet material and spraying it evenly inside the tower body 1. For the specific structural form and implementation principle of the atomizer 2, please refer to existing technology; this embodiment will not elaborate further. Figure 3 As shown, in this embodiment, the atomizer 2 is specifically supported and fixed inside the tower body 1 by the support arm 22. The specific structure of the drive assembly 3 can be found in [reference needed]. Figure 3It includes a drive motor 31, a drive member 32, and a driven member 33 that is driveably connected to the drive member 32. The driven member 33 is fitted outside the atomizer 2 and rotatably connected to the atomizer 2. The drive motor 31 is connected to the drive member 32 to drive the driven member 33 to rotate. In this embodiment, the drive motor 31 has a rotation output end, and the drive member 32 is connected to the rotation output end of the drive motor 31. When the drive motor 31 is started, it can drive the drive member 32. Since the drive member 32 is driveably connected to the driven member 33, when the drive member 32 rotates, it will drive the driven member 33 to rotate around the axis of the atomizer 2. In this embodiment, the atomizer 2 and the driven member 33 are rotatably connected. Specifically, as shown in the figure... Figure 3 As shown, in this embodiment, a boss 21 protrudes from the outer periphery of the atomizer 2. The driven member 33 is fitted onto the atomizer 2, and the boss 21 abuts against the bottom surface of the driven member 33 to limit and support the driven member 33, allowing the driven member 33 to rotate circumferentially around the atomizer 2. Alternatively, a groove can be formed on the outer periphery of the atomizer 2, and a slider can be fixedly installed on the inner wall of the driven member 33, allowing the slider to be inserted into the groove and slidably connected to it. This also achieves the purpose of allowing the driven member 33 to rotate circumferentially relative to the atomizer 2. There are also other implementation methods, which will not be listed in this embodiment. Any conversion method falls within the scope of protection of this application. An angle adjustment component 4 is fixedly installed below the driven member 33, specifically as shown... Figure 3 As shown, the angle adjustment assembly 4 includes a telescopic rod 41, a connecting rod 42, and an adjusting plate 43. The telescopic rod 41 is a common electric telescopic rod device in the field, with one end fixedly connected to the lower end face of the driven member 33 and the other end rotatably connected to the adjusting plate 43. One end of the connecting rod 42 is fixedly connected to the lower end face of the driven member 33, and the other end rotatably connected to the adjusting plate 43. The adjusting plate 43 is located below the atomizer 2, specifically below the nozzle of the atomizer 2, and is used to control the spray angle of the material. The adjusting plate 43 is bent into a "U" shape. The telescopic rod 41 can extend and retract to drive the adjusting plate 43 to rotate around the rotatable connection between the connecting rod 42 and the adjusting plate 43 to achieve pitch angle adjustment. The drying air assembly 5 is used to supply drying air into the tower body 1 to dry the material sprayed from the atomizer 2. The dried material is discharged uniformly through the material outlet 10.

[0039] The electrode material drying device has a simple overall structure. The direction of the material sprayed from the atomizer 2 is adjustable. The drive motor 31 drives the driven component 33 to rotate via the drive component 32. When the drive component 32 rotates, it drives the driven component 33 and the adjusting plate 43 installed below the driven component 33 to rotate synchronously. Since the adjusting plate 43 is located below the nozzle of the atomizer 2, when the drive motor 31 is started, the adjusting plate 43 can rotate around the circumference of the atomizer 2 below the nozzle. Under the guidance of the adjusting plate 43, the angle of the material sprayed from the atomizer 2 is adjusted. The angle is adjustable, and under the telescopic adjustment of the telescopic rod 41, the adjusting plate 43 can rotate around the rotating connection between the connecting rod 42 and the adjusting plate 43 to further adjust the pitch angle of the adjusting plate 43, and further adjust the angle of the material sprayed by the atomizer 2, so as to achieve flexible adjustment of the angle of the material sprayed by the atomizer 2, and flexibly adjust the contact angle and range between the sprayed material and the drying air, so that the material can be fully mixed and contacted with the drying air, improving the drying efficiency and effectively preventing uneven drying of the material, which affects the consistency of the material quality.

[0040] Optionally, such as Figure 3 In this embodiment, the driving component 32 is a worm gear, and the driven component 33 is a turbine. The worm gear meshes with the turbine for transmission. The turbine is mounted on the atomizer 2 and placed on the boss 21. The radial dimension of the boss 21 is smaller than the radial dimension of the turbine. The telescopic rod 41 and the connecting rod 42 are both fixedly connected to the lower end face of the turbine. The rotation output end of the drive motor 31 is connected to the worm gear. When the drive motor 31 starts, it can drive the turbine and the telescopic rod 41, connecting rod 42, and adjusting plate 43 below it to rotate synchronously. Alternatively, the driving component 32 can also be a gear, and the driven component 33 can also be a gear ring. The gear meshes with the gear ring for transmission. The gear ring is mounted outside the atomizer 2 and placed on the boss 21. The gear ring can rotate relative to the atomizer 2. When the drive motor 31 passes through the gear, it can drive the gear ring to rotate. When the gear ring rotates, it drives the gear ring and the telescopic rod 41, connecting rod 42, and adjusting plate 43 below it to rotate synchronously. This can also achieve the same purpose, and can be selected according to the actual situation.

[0041] Furthermore, the electrode material drying apparatus also includes a storage tower assembly 6 for storing materials, such as... Figure 4 As shown, the storage tower assembly 6 includes a storage tower 61, a drive pump 62, and a material pipeline 63. The material pipeline 63 is connected to the storage tower 61 and the atomizer 2. The drive pump 62 is mounted on the material pipeline 63 and is used to pump the material. It is understood that in this embodiment, the wet electrode material is uniformly stored in the storage tower 61, which includes a detachably connected storage tower body and a storage tower cover. In this embodiment, the drive pump 62 is a centrifugal pump, which is used to pump the wet material in the storage tower 61 to the atomizer 2 via the material pipeline 63.

[0042] Furthermore, such as Figure 1As shown, the drying air assembly 5 includes a fan 51 and a drying air duct 52. One end of the drying air duct 52 is connected to the fan 51, and the other end is connected to the tower body 1. The fan 51 is used to draw outside air through the drying air duct 52 to the tower body 1 to form drying air. Optionally, the drying air assembly 5 in this embodiment may also include a heating module. The heating module can be used to heat the outside air drawn by the fan 51 to form hot drying air, further improving the drying efficiency of wet materials. The heating module can be a conventional heating component such as an electric heating wire, selected as appropriate. This embodiment does not specifically limit this.

[0043] Furthermore, such as Figure 1 As shown, the drying air assembly 5 also includes a guide box 53, which is connected between the drying air duct 52 and the tower body 1. The guide box 53 has one air inlet 531 and several air outlets 532. The drying air duct 52 is connected to the air inlet 531, and the several air outlets 532 are connected to the tower body 1. In this embodiment, the guide box 53 has a rectangular structure, with three air outlets 532 spaced vertically on its upper surface. The drying air entering through the air inlet 531 is divided into three streams by the guide box 53 and enters the tower body 1, so as to make the air intake in the tower body 1 uniform and improve the drying effect.

[0044] Optionally, such as Figure 1 As shown, the electrode material drying device in this embodiment also includes a collection box 7. The collection box 7 is an open-top box structure with a handle and rollers at the bottom to facilitate pulling the collection box 7. When the electrode material drying device is started, the collection box 7 is pushed and pulled below the material outlet 10 to collect the dried material in a unified manner.

[0045] Furthermore, such as Figure 2 As shown, the tower body 1 includes a tower body 11, a guide pipe 12, a cover plate 13, and a support frame 14. The cover plate 13 is rotatably connected to the tower body 11. The guide pipe 12 is located at the bottom of the tower body 11 and is connected to the tower body 11. The bottom of the guide pipe 12 has a material outlet 10. The support frame 14 is used to support the tower body 11. In this embodiment, the guide pipe 12 is funnel-shaped so that the dried and settled material can slide along the wall of the guide pipe 12 to the material outlet 10, preventing material accumulation. The cover plate 13 is rotatably connected to the tower body 11 and can be opened at any time to check the internal condition of the tower body 1 or to inspect the internal structure of the tower body 1. The support frame 14 can lift the tower body 11 to a certain height to facilitate the placement of the collection box 7 below the material outlet 10.

[0046] Optionally, the tower body 1 further includes a first adapter rod 15 and a second adapter rod 16 rotatably connected. The first adapter rod 15 is rotatably connected to the tower body 11, and the second adapter rod 16 is rotatably connected to the cover plate 13. In this embodiment, the cover plate 13 is rotatably connected to the tower body 11 through the first adapter rod 15 and the second adapter rod 16. Alternatively, the cover plate 13 can be directly rotatably connected to the tower body 11, including but not limited to the method shown in the accompanying drawings of this embodiment. Preferably, the cover plate 13 is provided with a handle to facilitate opening the cover plate 13.
