[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will elaborate on various embodiments of the present invention in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in various embodiments of the present invention, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in each claim of the present application can still be achieved.

[0040] The first embodiment of the present invention relates to a ternary lithium powder distributor, as Figure 2 and Figure 3 shown, including:

[0041] The cylinder 1 is used to hold the ternary lithium molten salt; it serves as a buffer for the ternary lithium molten salt during dripping; it cannot directly cause the dripping of the ternary lithium molten salt to be out of control;

[0042] The droplet control device 100 is provided with a plurality of droplet control devices 100 from top to bottom above the cylinder 1. The droplet control device 100 is mainly used to control the falling speed of the droplets of the ternary lithium molten salt.

[0043] In the first embodiment of the present invention, the liquid inlet 2 is arranged above the cylinder 1; the ternary lithium molten salt enters the cylinder 1 from the liquid inlet 2, and the droplet control device 100 is used to control the speed of the droplets of the ternary lithium molten salt.

[0044] The anti-blocking pipe 3 is arranged below the cylinder 1. The anti-blocking pipe 3 extends into the cylinder 1. In the first embodiment of the present invention, the anti-blocking pipe 3 serves to observe whether the droplet control device 100 is blocked. When the droplet control device 100 is blocked, the ternary lithium molten salt will overflow from the anti-blocking pipe 3 and fall. When the droplet control device 100 is normal, under the control of the droplet control device 100, the ternary lithium molten salt entering the cylinder 1 and the ternary lithium molten salt dripping out of the cylinder 1 reach an equilibrium state. The droplet control device 100 in the first embodiment of the present invention can achieve the technical effect of controlling the falling speed of the droplets of the ternary lithium molten salt.

[0045] In addition, the droplet control device 100 in the first embodiment of the present invention, as Figure 2 and Figure 3 shown, further includes:

[0046] A liquid guiding needle 4 is penetrated through the cylinder body 1, and one end of the liquid guiding needle 4 penetrates into the liquid dripping hole 5 opened below the cylinder body 1; one end of the liquid guiding needle 4 penetrates through the cylinder body 1, and the liquid guiding needle 4 and the liquid dripping hole 5 constitute a liquid drop control device 100. The ternary lithium molten salt drips out between the liquid guiding needle 4 and the liquid dripping hole 5, forming the liquid drop control device 100, thereby achieving the technical effect of controlling the falling speed of the ternary lithium molten salt droplets.

[0047] Further, for the liquid drop control device 100 in the first embodiment of the present invention, as Figure 2 , Figure 3 , Figure 4 shown, a section of thread 6 is provided at the other end of the liquid guiding needle 4 for fixed connection with the cylinder body 1, and a thread head 7 is provided at the rear end of the thread 6 for tightening the liquid guiding needle 4. The liquid guiding needle 4 is fixed to the cylinder body 1 by using the thread 6, and a thread head 7 is provided at the rear end of the thread 6 for tightening the liquid guiding needle 4, forming the liquid drop control device 100.

[0048] In addition, in the second embodiment of the present invention, as Figure 5 shown, the other end of the liquid guiding needle 4 is set to a smooth surface and fits and seals with the through hole 8 on the cylinder body 1. In this way, the liquid guiding needle 4 can slide in the through hole 8, providing a basis for the subsequent control of the liquid drop control device 100.

[0049] In the second embodiment of the present invention, as Figure 5 shown, the liquid guiding needle 4 further includes:

[0050] A needle-shaped valve core 9 is provided at the inner wall of the liquid guiding needle 4 near the lower part of the cylinder body 1. The needle-shaped valve core 9 is set to be conical and fits with the conical inclined surface provided on the liquid dripping hole 5. If the liquid drop control device 100 needs to be closed, as long as the needle-shaped valve core 9 and the liquid dripping hole 5 are completely fitted, the liquid drop control device 100 can be closed. As long as the opening between the needle-shaped valve core 9 and the liquid dripping hole 5 is controlled, the falling speed of the ternary lithium molten salt droplets can be controlled.

[0051] In the second and third embodiments of the present invention, as Figure 5 , Figure 7 shown, a stroke control device is connected to the rear side of one end of the liquid guiding needle 4. The stroke control device is connected to one end of the liquid guiding needle 4 through a thread. The stroke control device is used to control the stroke of the liquid guiding needle 4, control the opening size between the liquid guiding needle 4 and the liquid dripping hole 5, and control the speed of the ternary lithium molten salt droplets.

[0052] As Figure 6As shown, in the second embodiment of the present invention, the stroke control device is a cylinder 10. The cylinder 10 is controlled by a pneumatic valve 11. The pneumatic valve 11 controls the stroke operation of the cylinder 10. The pneumatic valve 11 is electrically connected to a control system (not shown in the figure). The cylinder 10 controls the stroke of the liquid guide needle 4. In this embodiment, the cylinder 10 drives the liquid guide needle 4 to move, thereby controlling the opening size between the liquid guide needle 4 and the liquid dripping hole 5. Whether the liquid guide needle 4 is a smooth rod or is provided with a needle-shaped valve core 9, the speed of the droplets of the ternary lithium molten salt can be controlled.

[0053] As Figure 7 shown, in the second embodiment of the present invention, the stroke control device is a servo motor 12. The servo motor 12 is electrically connected to the control system. A lead screw device 13 is connected to the servo motor 12. The lead screw device 13 is connected to the rear side of one end of the liquid guide needle 4. The servo motor 12 drives the lead screw device 13 to control the stroke of the liquid guide needle 4. Similarly, in this embodiment, the servo motor 12 drives the liquid guide needle 4 to move, thereby controlling the opening size between the liquid guide needle 4 and the liquid dripping hole 5. Whether the liquid guide needle 4 is a smooth rod or is provided with a needle-shaped valve core 9, the speed of the droplets of the ternary lithium molten salt can be controlled.

[0054] Considering the second embodiment and the third embodiment of the present invention comprehensively, the droplet control device 100 in the embodiment can be arranged in a row or in multiple rows and columns side by side above the cylinder body 1, which can be determined according to the speed of the droplets of the ternary lithium molten salt and the production speed of ternary lithium molten salt powder making.

[0055] In the fourth embodiment of the present invention, a ternary lithium powder distributor device is further provided, as Figure 1 、 Figure 8 shown, including:

[0056] Among any one of the distributors in the first embodiment, the second embodiment and the third embodiment of the present invention, the structure of the distributor can be a combination of the embodiments of the present invention, with a total of 4 structural ways of the distributor;

[0057] The distributor in the above embodiment is fixed to the frame 14 through a fixing plate 15 provided on the distributor; the liquid dripping holes 5 on the distributor are located above the cooling drum 16;

[0058] Cooling drum 16, with first bearings 17 provided on both sides of the frame 14. A support shaft 18 of the cooling drum 16 is fixed within the first bearings 17. One end of the support shaft 18 is fixedly connected to the end face of the cooling drum 16, and the other end of the support shaft 18 is disposed outside the first bearings 17. The cooling drum 16 rotates within the first bearings 17 by means of the support shaft 18, enabling the cooling drum 16 to rotate within the frame 14. Thus, when the liquid drops of ternary lithium molten salt drip from the liquid dropping holes 5 on the distributor, the liquid drops of ternary lithium molten salt can be transferred to below the cooling drum 16 through the cooling drum 16 for convenient collection.

[0059] In this embodiment, as Figure 8 shown, the surface of the cooling drum 16 has a smooth structure, and the cooling drum 16 is cylindrical. The smooth structure of the surface of the cooling drum 16 helps the liquid drops of ternary lithium molten salt to smoothly separate from the cooling drum 16. The cylindrical shape of the cooling drum 16 is more conducive to rotation.

[0060] Second bearing 19, with the second bearing 19 fixed within the inner hole of the support shaft 18, and a cooling water pipe 20 fixedly connected within the inner hole of the second bearing 19. Thus, when the cooling drum 16 rolls, since the second bearing 19 is fixed within the inner hole of the support shaft 18 and the cooling water pipe 20 is fixedly connected within the inner hole of the second bearing 19, as long as the cooling water pipe 20 is fixed, the cooling water pipe 20 will not rotate along with the cooling drum 16. In this way, it is convenient to introduce cooling water into the cooling water pipe 20 to cool the cooling drum 16.

[0061] In addition, the cooling water pipe 20 extends into the cavity within the cooling drum 16. A cooling water circuit is connected to the cooling water pipe 20 for cooling the cooling drum 16, making the cooling of the cooling drum 16 more uniform. Thus, when the liquid drops of ternary lithium molten salt drip onto the cooling drum 16, they can be quickly cooled. At the same time, the cooling drum 16 is also rotating, and the liquid drops of ternary lithium molten salt dripping onto the cooling drum 16 are quickly cooled and separated from the cooling drum 16, thereby forming large particles of ternary lithium molten salt.

[0062] To achieve the above technical effects and to rotate the cooling drum 16, a passive wheel 21 is fixed on the support shaft 18 of the cooling drum 16;

[0063] The motor 22 is fixed on a motor mounting plate 23 fixedly connected to one side of the frame 14;

[0064] A driving wheel 24 is axially connected to the driving shaft of the motor 22; The driving wheel 24 and the passive wheel 21 are connected by a driving belt 25. In this way, the motor 22 drives the cooling drum 16 to rotate; Thus, a structure in which the motor 22 drives the cooling drum 16 to rotate is formed.

[0065] In order to prevent the droplets of ternary lithium molten salt on the cooling drum 16 from splashing during the rotation of the cooling drum 16, a protective cover 26 is provided above the cooling drum 16; the distributor is fixed in a square hole 27 opened on the protective cover 26; the cooling drum 16 is arranged below the square hole 27.

[0066] In this embodiment, when the droplets of ternary lithium molten salt in the liquid dropping holes 5 on the distributor drip down, the cooling drum 16 can cool the droplets of ternary lithium molten salt. At the same time, the cooling drum 16 is still rotating, and the droplets of ternary lithium molten salt dripping onto the cooling drum 16 are quickly cooled and separated from the cooling drum 16 to form large particles of ternary lithium molten salt. Since the protective cover 26 blocks the large particles of ternary lithium molten salt that may splash, the large particles of ternary lithium molten salt fall into a collection machine (not shown in the figure).

[0067] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present invention, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present invention.
