Description

Technical Field

[0001] This utility model relates to a lithium deposition reactor, and more particularly to a double-bladed lithium deposition reactor, belonging to the field of lithium battery material preparation technology. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. The lithium metal battery was first proposed and researched by Gilbert N. Lewis in 1912. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become mainstream. They can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, the lithium metal battery, was developed in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to lithium-ion batteries. Due to its high technical requirements, only companies in a few countries produce lithium metal batteries. The production of lithium-ion batteries involves using a lithium-ion deposition reactor for material preparation.

[0003] A search revealed a lithium deposition reactor for high-efficiency separation of lithium battery materials, with publication number CN212040446U.

[0004] The existing lithium deposition reactor uses a rotating shaft to drive a rotating rod on its surface to rotate, mixing the lithium battery materials inside the reactor. This mixing method is relatively simple and cannot evenly mix the lithium battery materials inside the reactor. Moreover, during discharge, the lithium battery materials easily adhere to the inner wall of the reactor, seriously affecting the discharge effect.

[0005] Therefore, it is urgent to improve the existing lithium precipitation reactor to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a dual-paddle lithium deposition reactor that can solve the problem that existing lithium deposition reactors use a rotating shaft to drive a rotating rod on its surface to rotate and mix the lithium battery materials inside the reactor. This mixing method is relatively simple and cannot evenly mix the lithium battery materials inside the reactor. Moreover, during discharge, the lithium battery materials easily adhere to the inner wall of the reactor, seriously affecting the discharge effect.

[0007] To achieve the above objectives, the main technical solution adopted by this utility model includes: a double-paddle lithium deposition reactor, comprising a reactor body, a rotating shaft rotatably mounted inside the reactor body, stirring structures provided on both sides of the rotating shaft, a support base fixedly mounted on the upper end of the reactor body, a motor mounted on the upper end of the support base, the upper end of the rotating shaft movably inserted inside the support base, the upper end of the rotating shaft being drively connected to the output end of the motor, and an anti-sticking structure provided on one side of the reactor body.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figures 1 to 4 As shown, this embodiment provides a dual-blade lithium deposition reactor, including a reactor body 1. A rotating shaft 15 is rotatably installed inside the reactor body 1. Stirring structures are provided on both sides of the rotating shaft 15. A support base 5 is fixedly installed at the upper end of the reactor body 1. A motor 6 is installed at the upper end of the support base 5. The upper end of the rotating shaft 15 is movably inserted inside the support base 5. The upper end of the rotating shaft 15 is connected to the output end of the motor 6. An anti-sticking structure is provided on one side of the reactor body 1. The lower end of the reactor body 1 is conical. A discharge pipe 2 is provided at the lower end of the reactor body 1. A control valve 3 is provided on the surface of the discharge pipe 2. A feed pipe 4 is provided at the upper end of the reactor body 1.

[0026] In this invention, lithium battery material enters the interior of the reactor body 1 through the feed pipe 4. The motor 6 drives the rotating shaft 15 to rotate. The rotating shaft 15 can uniformly stir the lithium battery material through the stirring structure. After stirring, the control valve 3 is opened, and the mixture can be discharged through the discharge pipe 2. Under the action of the anti-sticking wall structure, the mixture can be prevented from adhering to the inner wall of the reactor body 1, which would affect the discharge effect.

[0027] like Figure 3 and Figure 4 As shown in the figure, this embodiment provides a dual-paddle lithium deposition reactor. The stirring structure includes rotating rods 16, which are fixedly installed on both sides of the rotating shaft 15. A movable scraper 17 is fixedly installed between the two rotating rods 16 located on the same vertical line. The movable scraper 17 is in contact with the inner wall of the reactor body 1. The movable scraper 17 is perpendicular to the rotating rods 16, and the rotating rods 16 are perpendicular to the rotating shaft 15. Stirring racks 18 are provided on both sides of the lower end of the rotating rods 16. The stirring racks 18 are connected to the inner wall of the reactor body 1. The two sides of the lower end of the vessel body 1 are attached to each other. A stirring rod is provided on both sides of the rotating shaft 15. The stirring rod is located between two rotating rods 16. A rotating rod 19 is rotatably installed between the two rotating rods 16 located on the same vertical line. A meshing gear 20 is fixedly installed on the upper end of the rotating rod 19. A meshing tooth ring 21 is provided on both sides of the upper end of the vessel body 1. The meshing gear 20 meshes with the meshing tooth ring 21. A stirring plate 22 is provided on both sides of the rotating rod 19. A material leakage groove 23 is opened on both sides of the stirring plate 22.

[0028] In this invention, the motor 6 drives the rotating shaft 15 to rotate, which in turn rotates the stirring rod and the stirring frame 18, thus stirring the materials. The rotating shaft 15 drives the movable scraper 17 to rotate via the rotating rod 16, which scrapes the inner wall of the vessel body 1 to prevent materials from adhering to the inner wall. When the rotating rod 16 rotates inside the vessel body 1, the meshing gear 20 rotates inside the meshing tooth ring 21. Under the action of the meshing tooth ring 21, the meshing gear 20 drives the rotating rod 19 to rotate, which in turn drives the stirring plate 22 to rotate, further enhancing the mixing effect.

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a dual-paddle lithium deposition reactor with an anti-sticking structure including a contact plate 10. The contact plate 10 is fixedly installed on one side of the reactor body 1. Mounting plates 7 are fixedly installed at both ends of one side of the contact plate 10. An adjusting crankshaft 8 is rotatably installed between the two mounting plates 7. The adjusting crankshaft 8 is connected to the rotating shaft 15. Mounting rods 11 are fixedly installed at both ends of the contact plate 10. A stop block 12 is fixedly installed at one end of the mounting rod 11. A buffer spring 13 is sleeved on the surface of the mounting rod 11. One end of the buffer spring 13 is connected to the stop block 12. A vibrating plate 14 is movably installed between the two mounting rods 11. The vibrating plate 14 is connected to the buffer spring 13. Two movable connecting rods 9 are movably installed on one side of the vibrating plate 14. The movable connecting rods 9 are movably connected to the adjusting crankshaft 8.

[0030] In this invention, when the rotating shaft 15 rotates, the rotating shaft 15 drives the adjusting crankshaft 8 to rotate through the transmission sprocket and transmission chain. The adjusting crankshaft 8 drives one end of the movable connecting rod 9 to make a circular motion. The movable connecting rod 9 drives the vibrating plate 14 to move repeatedly along the mounting rod 11, so that the vibrating plate 14 can repeatedly strike the contact plate 10, causing the reactor body 1 to vibrate, avoiding the adhesion of mixed material inside the reactor body 1, and enhancing the discharge effect.
