Detailed Implementation
[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0023] like Figure 1 As shown, the mixing device 100 in one embodiment of this utility model includes a frame 10, a mixing tank 20, a drive assembly, and an adjustment assembly 40. The mixing tank 20 is fixed to the frame 10, and a rotatable drive shaft 21 is provided inside it. A stirring blade 22 for stirring raw materials is provided on the drive shaft 21. The drive assembly is fixed to the frame 10 and includes a drive motor 31, a drive wheel 32, a driven wheel 33, and a belt 34. The driven wheel 33 is fixedly connected to the drive shaft 21, and the drive wheel 32 is fixed to the output shaft of the drive motor 31 and connected to the driven wheel 33 via the belt 34. The adjustment assembly 40 is fixed to the frame 10 and is used to adjust the tension of the belt 34.
[0024] After the raw materials are put into the mixing tank 20 in this embodiment, the drive motor 31 drives the drive wheel 32 to rotate. The drive wheel 32 drives the driven wheel 33 to rotate via the belt 34, which in turn drives the transmission shaft 21 and the stirring blade 22 to rotate, thus mixing the raw materials. During operation, the tension of the belt 34 is adjusted by the adjusting component 40 to prevent the belt from loosening and slipping after prolonged use, thereby ensuring the normal operation of the equipment.
[0025] Specifically, the adjustment assembly 40 includes an electric cylinder 41 and a contact element. The electric cylinder 41 is fixed on the frame 10, and the contact element is fixed to the output end of the electric cylinder 41. Under normal working conditions, the contact element does not contact the belt 34. When the belt 34 is too loose, the electric cylinder 41 drives the contact element to approach and contact the belt 34, and pushes the belt 34 in a direction perpendicular to the transmission direction of the belt 34 at the contact position, so that the belt 34 is tensioned and maintains normal friction between the belt 34 and the drive wheel 32 and the driven wheel 33.
[0026] In such Figure 2 In the embodiment shown, the adjustment component 40 is disposed between the drive wheel 32 and the driven wheel 33, that is, on the inner side of the belt 34, and the electric cylinder 41 drives the contact member to move to the outer side of the belt 34.
[0027] In one embodiment, such as Figure 3 As shown, the electric cylinder 41 is connected to a mounting bracket 42, and the aforementioned contact element is a movable roller 43 fixed on the mounting bracket 42. The movable roller 43 and the belt 43 are in rolling contact, which results in less friction and less heat generation compared to sliding contact. Therefore, the belt 34 has a longer service life, further ensuring the stable operation of the equipment for a long time.
[0028] Preferably, a pressure sensor 44 is also provided between the electric cylinder 41 and the mounting bracket 42 to monitor the squeezing force between the movable roller 43 and the belt 34 in real time, so as to assist in adjusting the position of the movable roller 43, so that the belt 34 and the drive wheel 32 and the driven wheel 33 always maintain a relatively stable friction force, and avoid the situation that the belt 34 is too loose and therefore the friction force is insufficient, or the belt 34 is too tight and therefore the friction force is too large.
[0029] In one embodiment, a vibration assembly 50 is provided on the mixing tank 20. The vibration assembly 50 includes a fixed seat 51 fixed on the outer wall of the mixing tank 20 and a vibration mechanism provided on the fixed seat 51. The vibration mechanism is used to drive the fixed seat 51 to generate high-frequency vibration on the mixing tank 20 to prevent raw materials from adhering.
[0030] Specifically, such as Figure 4 As shown, the vibration mechanism for driving the fixed base 51 to vibrate includes a protective shell 52, an eccentric wheel 53, and a servo motor 54. The protective shell 52 is fixed on the fixed base 51, the eccentric wheel 53 is disposed inside the protective shell 52, and the servo motor 54 is mounted on the protective shell 52. It is connected to and drives the eccentric wheel 53 to rotate inside the protective shell 52. In this way, the vibration assembly 50 can generate high-frequency vibration on the mixing barrel 20, thereby preventing the raw materials from adhering to the inner wall of the mixing barrel 20.
[0031] Preferably, a plurality of vibration components 50 are provided on the mixing barrel 20, and the vibration components 50 are evenly distributed on the outer wall of the mixing barrel 20 to create multiple vibration points on the entire mixing barrel 20, so that stable vibration can be generated at each position on the mixing barrel 20, thereby avoiding the situation where the vibration effect at some positions is insufficient and raw materials still adhere.
[0032] like Figure 1 As shown, the mixing tank 20 is provided with a feeding port 23 and a discharging port 24. The feeding port 23 is located at the top of the mixing tank 20, while the discharging port 24 is located at the bottom of the mixing tank 20. To facilitate the discharge of abrasive, an air pump 60 is provided on the frame 10 and connected to the mixing tank 20. When it is necessary to discharge abrasive, the air pump 60 is activated to blow air into the mixing tank 20 to discharge the abrasive from the discharging port 24.
[0033] Preferably, the air pump 60 is connected to the top of the mixing tank 20, and a solenoid valve 61 is provided on the pipe connecting the air pump 60 and the mixing tank 20. The solenoid valve 61 is opened only when air is needed, and closed at other times to prevent abrasive from entering the pipe.
[0034] In one embodiment, the frame 10 includes a top plate 11 and a bottom plate 12. The air pump 60 is fixed to the bottom plate 12, the aforementioned drive motor 31 and servo motor 54 are fixed to the upper surface of the top plate 11, and the drive wheel 32, driven wheel 33, and adjustment assembly 40 are fixed to the lower surface of the top plate 11. This arrangement can, to a certain extent, prevent foreign objects from entering between the belt 34 and the drive wheel 32 or driven wheel 33, thereby ensuring the stable operation of the equipment for a long time.
[0035] Preferably, a controller 13 is also fixed on the frame 10, which connects the air pump 60, the drive motor 31 and the servo motor 54. The controller 13 is fixed on the top plate 11, and the on and off of the air pump 60, the drive motor 31 and the servo motor 54 can be controlled by the controller 13 without separate control.
[0036] Taking the preparation of lithium manganese iron phosphate as an example, the doping and mixing device 100 in this embodiment will be further explained.
[0037] Lithium manganese iron phosphate (LMFP) is a novel phosphate-based lithium-ion battery cathode material formed by doping lithium iron phosphate with a certain proportion of manganese. It shares the same structure as lithium iron phosphate, both being ordered and well-organized olivine-type structures. LMFP is considered an upgraded version of lithium iron phosphate, possessing advantages such as chemical stability and excellent safety performance. The production of lithium manganese iron phosphate involves two methods: solid-phase and liquid-phase. The solid-phase method involves grinding and mixing raw materials such as lithium, iron, manganese, and phosphorus sources, followed by carbon coating and sintering.
[0038] First, raw materials such as lithium, iron, manganese, and phosphorus are added from the top feed port 23. The drive motor 31 drives the driven wheel 33 to rotate through the drive wheel 32 and belt 34, which in turn drives the transmission shaft 21 and the stirring blade 22 to rotate. The stirring blade 22 stirs the raw materials to make them fully mixed.
[0039] During the mixing process, the servo motor 54 drives the eccentric wheel 53 to rotate and generate vibration. The vibration is transmitted to the mixing barrel 20 through the protective shell 52 and the fixed base 51, so that it maintains a high frequency of slight vibration and prevents the abrasive from adhering to the inner wall of the mixing barrel 20.
[0040] As the raw materials are mixed, the discharge port 24 opens to discharge the material. The air pump 60 and the solenoid valve 61 start synchronously and continuously pump air into the mixing tank 20. The air pressure inside the mixing tank 20 increases, and the gas rushes out along the discharge port 24, pushing the powder to flow out quickly. At the same time, the wind can send out the residual powder inside the mixing tank 20.
[0041] During operation, the movable roller 43 presses against the belt 34, and the pressure sensor 44 senses the pressure from the belt to determine the tension. Based on the feedback of the tension, the electric cylinder 41 extends or retracts to adjust the tension, so that the transmission always remains in a stable state.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
