Various processing equipment will be used in this preparation process.

[0003] For example, the utility model with the existing patent application number: 202321899208.2 relates to the technical field of sodium ion battery positive electrode production, and specifically discloses a special mixing tank for sodium ion battery positive electrode materials. A special mixing tank for sodium ion battery positive electrode materials, including a tank body, a drive motor, and a controller, wherein a stirring shaft is fixedly installed at one end of the output shaft of the drive motor. In the utility model, when the lifting seat moves upward to pull out the decontamination plate and the decontamination brush from the groove, the lifting seat is plugged into the card block, and then the rotation of the stirring shaft can drive the lifting seat and the decontamination plate to rotate, clean the inner wall of the tank body, and remove the residual electrode slurry inside the tank body. The lifting seat moves downward, the card block is separated from the card slot, and the decontamination plate and the decontamination brush are inserted into the groove. When the stirring shaft rotates, the lifting seat will not rotate with it.

[0004] During the use of the mixing tank, in order to ensure the internal sealing of the mixing tank, the valve body is often required as a discharge control. However, when discharging materials with hard particles from the mixing tank, the valve plate is easily stuck, resulting in poor sealing of the mixing tank, and the valve plate wears quickly, causing damage to the valve body.

[0024] The utility model embodiment provides a sodium ion battery positive electrode material preparation device.

[0025] See also Figure 1 , Figure 2 , Figure 3and Figure 4 , including a tank body 1 and a driving motor 2, the tank body 1 has a discharge port fixedly connected to a discharge pipe 17, a flared pipe 18 fixedly connected inside the discharge pipe 17, a rubber thin-walled tube 19 fixedly connected to the bottom of the flared pipe 18, a rotating disk 9 is arranged at the bottom of the discharge pipe 17, a transmission structure is arranged between the rotating disk 9 and the driving motor 2, two circular holes 12 and two grooves 14 are arranged on the top of the rotating disk 9, and rubber tubes 13 are arranged inside the two circular holes 12.

[0026] When the utility model is in use: the first pulley 4 in the transmission structure is fixedly connected with a one-way bearing 5 inside, and the first pulley 4 and the one-way bearing 5 are both rotatably connected to the bottom of the tank body 1, and the first pulley 4 and the one-way bearing 5 sleeved on the outside of the output end of the drive motor 2 can rotate. When the drive motor 2 is working in the forward direction, the direction of rotation of the output end of the drive motor 2 is the self-rotation direction of the inner and outer rings of the one-way bearing 5, and the inner ring of the one-way bearing 5 rotates while the outer ring does not rotate, so the first pulley 4 with the outer ring of the one-way bearing 5 fixed does not rotate, and the drive motor 2 normally provides power for the internal structure of the tank body 1. When the drive motor 2 is working in the reverse direction, the direction of rotation of the output end of the drive motor 2 is the self-locking direction of the inner and outer rings of the one-way bearing 5, so the one-way bearing 5 rotates as a whole, driving the first pulley 4 to rotate.

[0027] The transmission structure also has a vertical shaft 6 installed in it, which is rotatably connected between the rotating disk 9 and the tank body 1. The second pulley 7 fixedly sleeved outside the vertical shaft 6 and the first pulley 4 form a transmission relationship through the belt 8, so the rotating first pulley 4 drives the second pulley 7 to rotate through the belt 8, so that the second pulley 7 drives the rotating disk 9 to rotate through the vertical shaft 6. The working time of the driving motor 2 is controlled to make the rotating disk 9 rotate 90°, and a rubber tube 13 fixed on the top of the rotating disk 9 moves between the discharge pipe 20 and the discharge pipe 17. Since one end of the discharge pipe 20 is set at the bottom of the discharge pipe 17, the discharge pipe 17, the rubber tube 13 and the discharge pipe 20 fixedly connected to the tank body 1 now form a discharge channel. A rubber thin-walled tube 19 is fixedly connected to the bottom of the expanded tube 18 fixedly connected inside the discharge tube 17. The expanded tube 18 with a larger inner diameter at the top and a smaller inner diameter at the bottom collects the materials, and the rubber thin-walled tube 19 guides the materials. The bottom of the rubber thin-walled tube 19 is located at the bottom of the rubber tube 13, which can prevent the materials from entering the position where the rubber tube 13 contacts the discharge tube 17 and the discharge tube 20, prevent the movement of the rotating disk 9 from being stuck by the materials, and reduce the wear rate of the rotating disk 9.

[0028] After unloading is completed, the control driving motor 2 is reversed once again, so that the rotating disk 9 rotates 90°, and the pad 15 is placed inside the groove 14 opened in the rotating disk 9, so that the pad 15 enters between the discharge pipe 17 and the discharge pipe 20, seals the discharge pipe 17, seals the inside of the tank body 1, and the discharge channel is in a sealed state. The two rubber tubes 13 are symmetrically arranged on both sides of the top of the rotating disk 9, so when the control driving motor 2 is reversed for the third time, after the rotating disk 9 rotates 90°, another rubber tube 13 enters between the discharge pipe 17 and the discharge pipe 20, and the discharge channel is in an open state. The two grooves 14 are symmetrically arranged on both sides of the top of the rotating disk 9, and when the control driving motor 2 is reversed for the fourth time, the discharge channel enters a sealed state. According to the above mode, the discharge control structure composed of the transmission structure, the rotating disk 9, and the rubber tube 13 can meet the processing and discharge work of the tank body 1, and avoid the situation where the particles in the material cause the discharge pipe 17 to be unable to be sealed.

[0029] A plurality of supporting bottom plates 11 are arranged at the bottom of the rotating disk 9, and fixed vertical rods 10 are fixedly connected between the plurality of supporting bottom plates 11 and the tank body 1. The rotating disk 9 is supported by the fixed vertical rods 10 and the plurality of supporting bottom plates 11 to ensure the working stability of the rotating disk 9. A supporting vertical rod 21 is fixedly connected to the bottom of one of the supporting bottom plates 11, and the bottom of the supporting vertical rod 21 is fixedly connected to the discharge pipe 20, so the position of the discharge pipe 20 is also fixed.

[0030] Since the rubber thin-walled tube 19 made of elastic material can be deformed, the rotation of the rotating disk 9 will cause the rubber thin-walled tube 19 to deform. When the rubber thin-walled tube 19 loses its obstruction and returns to its original shape, a sampling container 16 can be placed inside the groove 14, so that the sampling container 16 rotates into the rubber thin-walled tube 19. In this case, after controlling the tank body 1 to discharge materials briefly, the drive motor 2 is controlled to drive the rubber tube 13 fixed by the rotating disk 9 to the bottom of the discharge pipe 17, and then complete the discharge. A part of the material stored in the sampling container 16 is taken out, and a part of the processed material can be directly extracted from the discharge position of the tank body 1 to complete the material sampling work, avoiding the situation where most of the material in the tank body 1 can be discharged before sampling, and reducing the cost investment required for material rework.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
