[0002] Sodium-ion battery is a secondary battery that mainly relies on the movement of sodium ions between the positive and negative electrodes to work. Similar to the working principle of lithium-ion batteries, the electrolyte is an important component structure in sodium-ion batteries. During the processing of sodium-ion batteries, a stirring device is required to stir and mix the sodium battery electrolyte materials.

[0003] Then, during the stirring process of the sodium battery electrolyte material, the raw materials will precipitate, and the materials precipitated at the bottom and edge of the stirring tank are not easy to be stirred up, which leads to uneven mixing and poor mixing effect. In addition, the setting of the stirring mechanism inside the stirring tank is easy to block the flushing pipe during subsequent cleaning, making the cleaning more troublesome and the effect poor. For this reason, we propose a stirring device for sodium battery electrolyte materials. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 - Figure 4 The utility model provides a stirring device for sodium battery electrolyte material, comprising a stirring tank 1, a motor 3 is arranged on the upper surface of the stirring tank 1, a feed port is provided on the left side of the upper end of the stirring tank 1, so that the sodium battery electrolyte material can be put into the stirring tank 1 from the feed port, a discharge port is provided on the lower right end of the stirring tank 1, and a valve is arranged inside the discharge port, so that the sodium battery electrolyte after stirring is discharged from the discharge port for use, a sealing bottom plate 6 is fixedly installed inside the lower end of the stirring tank 1 by bolts 2, a rotating shaft 4 is connected to the power output end of the motor 3, and a circumferential surface of the rotating shaft 4 is provided with a sealing bottom plate 6, a sealing bottom plate 6 is fixedly installed inside the lower end of the stirring tank 1 by bolts 2, a rotating shaft 4 is connected to the power output end of the motor 3, and a sealing bottom plate 6 is fixedly installed inside the lower end of the stirring tank 1 by bolts 2, ... A stirring rod 5 is arranged, and a bottom stirring mechanism 7 is arranged at the upper end of the sealing bottom plate 6. The bottom stirring mechanism 7 includes a screw 701, and the screw 701 is threadedly connected to the middle of the sealing bottom plate 6, so that when the screw 701 rotates, it can move up and down inside the sealing bottom plate 6, and a ball 702 is arranged at the upper end of the screw 701, and a push rod 703 is abutted against the circumferential side wall of the ball 702, and a C-shaped block 704 is arranged at the end of the push rod 703 away from the ball 702, and a return spring 706 is arranged on the inner side wall of the C-shaped block 704, and a strip brush 705 is inserted at the outer end of the C-shaped block 704;

[0019] It should be noted that the ball 702 is rotatably mounted on the upper end of the screw 701. Therefore, when the push rod 703 rotates, the push rod 703 will always be in contact with the ball 702, so that the C-shaped block 704 can always clamp the slat brush 705, so that the slat brush 705 can smoothly stir the sediment at the bottom of the mixing tank 1.

[0020] A transmission mechanism 8 is provided at the upper end of the screw rod 701, and the transmission mechanism 8 includes a rotating rod 801. A cross slot is provided at the lower end of the rotating shaft 4. A cross plug-in block 802 matching the cross slot is provided at the upper end of the rotating rod 801. After the cross plug-in block 802 is plugged into the cross slot, when the rotating shaft 4 rotates, the rotating rod 801 can be driven to rotate through the cross plug-in block 802. A transmission gear 803 is provided on the circumferential surface of the lower end of the rotating rod 801. The left side of the transmission gear 803 is meshedly connected with a driven gear 804. The lower end of the driven gear 804 is rotatably installed on the sealing bottom plate 6 through a positioning rod. The left side of the driven gear 804 is meshedly connected with a rotating sleeve block 805 through a gear ring, and the lower end of the rotating sleeve block 805 is rotatably installed inside the sealing bottom plate 6. The arrangement can stably mount the driven gear 804 on the sealing bottom plate 6 without affecting the rotation of the driven gear 804, and through the transmission of the driven gear 804, the rotation directions of the rotating shaft 4 and the rotating sleeve 805 are opposite, and then the rotation directions of the stirring rod 5 and the strip brush 705 are opposite, so that the bottom of the stirring tank 1 can produce a more intense stirring effect, so that the sediment deposited at the bottom of the stirring tank 1 is stirred more smoothly, and the electrolyte is mixed more evenly and the quality is better. One end of the strip brush 705 close to the rotating sleeve 805 is hinged to the circumferential outer surface of the rotating sleeve 805, and the inner side wall of the rotating sleeve 805 is provided with a movable groove 9, and the inner end of the C-shaped block 704 and the return spring 706 are both arranged inside the movable groove 9.

[0021] It should be noted that the rotating rod 801 is rotatably connected to the rotating sleeve 805. Therefore, when the rotating rod 801 rotates, it will not directly drive the rotating sleeve 805 to rotate, but will drive the rotating sleeve 805 to rotate through the transmission gear 803, the driven gear 804 and the gear ring. The movable groove 9 is arranged in four groups in a circular array, so the push rod 703, the C-shaped block 704, the slat brush 705 and the return spring 706 are all arranged in four groups. The arrangement of multiple slat brushes 705 can stir the sediment at the bottom of the stirring tank 1 and the edge of the stirring tank 1 more violently, thereby preventing the sediment from being deposited at the bottom of the stirring tank 1 and affecting the mixing quality of the electrolyte.

[0022] The working principle and use process of the utility model are as follows: when the sodium battery electrolyte material needs to be stirred and mixed, the raw materials are first added into the stirring tank 1 through the feed port, and then the motor 3 is started, the motor 3 drives the rotating shaft 4 to rotate, the rotating shaft 4 rotates to drive the stirring rod 5 and the rotating rod 801 to rotate, the stirring rod 5 rotates to stir and mix the electrolyte material, the rotating rod 801 rotates to drive the rotating sleeve 805 to rotate through the transmission gear 803 and the driven gear 804, and then the rotating sleeve 805 drives the strip brush 705 to rotate, the strip brush 705 rotates to clean and stir the bottom of the stirring tank 1, so that the materials deposited at the bottom of the stirring tank 1 are stirred, thereby improving the mixing effect and mixing quality of the electrolyte, and after the electrolyte is mixed, the valve of the discharge port is opened to discharge the mixed electrolyte for use;

[0023] After all the electrolyte is discharged, the bolt 2 is unscrewed from the inside of the stirring tank 1, so that the sealing bottom plate 6 loses its fixing effect on the stirring tank 1, and then the screw rod 701 is rotated so that the screw rod 701 drives the ball 702 to move downward. At this time, the push rod 703 loses its limiting abutment effect, and the elastic force of the reset spring 706 is released, pushing the push rod 703 and the C-shaped block 704 toward the inside of the rotating sleeve block 805, thereby causing the C-shaped block 704 to lose its clamping and fixing effect on the strip brush 705. At this time, the sealing bottom plate 6 will move vertically downward. When the sealing bottom plate 6 moves downward, the strip brush 705 will rotate upward, and then the sealing bottom plate 6 and the components above it can be smoothly taken out from the inside of the stirring tank 1, which is convenient for cleaning the inside of the stirring tank 1 and the structure on the sealing bottom plate 6.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
