[0013] In the following description, embodiments of the lithium battery cathode material washing and drying apparatus of the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-5 This invention illustrates a washing and drying device for lithium battery cathode materials according to an embodiment of the present invention. The device includes a washing tank 1; a double-cone rotary vacuum dryer 2 is installed on the right side of the washing tank 1; a base support platform is installed at the bottom of the washing tank 1; a flanged water inlet pipe 13 is fixedly connected to the water inlet of the washing tank 1; an external water pipe is connected to the flanged water inlet pipe 13 via a water outlet valve 14 for easy water filling of the washing tank 1; an external drain pipe is connected to the water outlet valve 14 for easy subsequent wastewater discharge; a water outlet valve 14 is fixedly connected to the drain of the washing tank 1; a material basket 4 is installed on the top of the washing tank 1; the surface of the material basket 4 has several holes, the diameter of which is smaller than the diameter of the lithium battery cathode material; a rope is installed on the surface of the material basket 4; and hanging rings are installed on the surface of the rope. Fixed brackets 3 are provided on both the left and right sides of the material basket 4. A trapezoidal threaded rod 5 is rotatably connected between the two fixed brackets 3. A servo motor 6 is fixedly installed on the left side of one of the fixed brackets 3. The output shaft of the servo motor 6 is fixedly connected to one end of the trapezoidal threaded rod 5. A fixed steel plate 7 is fixedly connected between the two fixed brackets 3. A movable block 8 is sleeved on the surface of the trapezoidal threaded rod 5. The movable block 8 is threadedly connected to the trapezoidal threaded rod 5. A connector 9 is fixedly connected to the surface of the movable block 8. A slider 10 is fixedly connected to the surface of the connector 9. A limit rail 11 is fixedly connected to the surface of the fixed steel plate 7. The slider 10 is slidably connected to the limit rail 11. A lifting and hoisting assembly 12 is fixedly installed on the surface of the connector 9. The lifting and hoisting assembly 12 includes a motor, a reduction device, a braking device, a drum, a wire rope, and a hook.

[0015] Working Principle: In use, the user hangs the basket 4 containing the lithium battery positive electrode material on the hook of the lifting assembly 12, then starts the motor of the lifting assembly 12, causing the wire rope of the lifting assembly 12 to move the basket 4 downwards, so that the basket 4 enters the washing tank 1. The liquid in the washing tank 1 then enters the basket 4 through the holes on its surface to wash the positive electrode material. After washing, the lifting assembly 12 lifts the basket 4 out of the washing tank. The basket 4 is left to stand for a period of time to drain some of the water, and then the servo motor 6 is started, causing the output shaft of the servo motor 6 to drive the trapezoidal threaded rod 5 to rotate. The trapezoidal threaded rod 5 drives the moving block 8 to move to the right, so that the moving block 8 drives the slider through the connecting piece 9. 10 slides to the right on the surface of the limiting slide rail 11, thereby making the moving block 8 move more stably to the right. When the moving block 8 moves to the top of the feed inlet of the double cone rotary vacuum dryer 2, the servo motor 6 stops and the material basket 4 is lowered into the double cone rotary vacuum dryer 2 by the lifting and hoisting assembly 12. When the material basket 4 is lowered to the bottom, the hook on the wire rope of the lifting and hoisting assembly 12 is disengaged from the hanging ring on the material basket 4, and then it is lifted out of the double cone rotary vacuum dryer 2. Then the cover of the double cone rotary vacuum dryer 2 is sealed, so that the double cone rotary vacuum dryer 2 dries the positive electrode material in the material basket 4. This achieves the purpose of transferring the lithium battery positive electrode material from the washing pool to the dryer for drying through the moving lifting structure, thereby realizing and adapting to continuous production.

[0016] In summary, this lithium battery cathode material washing and drying device works by hanging the basket 4 on the hook of the lifting assembly 12, which then moves the basket 4 downwards into the washing tank 1 for washing. After washing, the lifting assembly 12 lifts the basket 4 out of the washing tank, causing the output shaft of the servo motor 6 to drive the moving block 8 to the right via the trapezoidal threaded rod 5. The moving block 8 moves to above the inlet of the double cone rotary vacuum dryer 2, and the lifting assembly 12 lowers the basket 4 into the double cone rotary vacuum dryer 2. When the basket 4 reaches the bottom, the hook on the wire rope of the lifting assembly 12 is released from the basket 4, and the cover of the double cone rotary vacuum dryer 2 is sealed. The double cone rotary vacuum dryer 2 then dries the cathode material in the basket 4. This achieves the goal of transferring lithium battery cathode materials from the washing tank to the dryer through a moving lifting structure, thus enabling continuous production.
