[0002] When manufacturing lithium-ion battery cathode materials, appropriate amounts of lithium carbonate and precursors need to be added to the mixing chamber of a mixing device and mixed thoroughly. After uniform mixing, the mixture is discharged and sintered to form the cathode material. However, during discharge, some material adheres to the cylinder baffle at the discharge port of the mixing device, causing a poor seal between the cylinder baffle and the discharge port. This results in some material falling off during subsequent mixing, affecting the cathode material's proportions and reducing its electrical performance. Utility Model Content

[0044] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, a mixing device is provided, comprising: a mixing component 1 having a mixing cavity, with a discharge port 101 on one side of the mixing cavity; a discharge component 2 having a first hollow cavity, one end of the discharge component 2 being fixedly connected to the discharge port 101, and the other end being used to output material; a sealing component 3 having a closed state of sealing the discharge port 101 and an open state fixed within the first hollow cavity; and a cleaning component 4 fixedly disposed within the first hollow cavity and adapted to the position of the sealing component 3 in the open state, the cleaning component 4 having a second hollow cavity and having an air inlet 401 and an air outlet 402, the cleaning component 4 being used to introduce cleaning gas through the air inlet 401 and blow air onto the sealing component 3 through the air outlet 402 to clean the sealing component 3.

[0046] By setting the mixing component 1, the materials can be mixed and mixed evenly; by setting the discharge component 2, the sealing component 3 and the cleaning component 4 can be supported and the discharge direction can be guided; by setting the sealing component 3, the discharge time and discharge speed of the materials can be controlled; by setting the cleaning component 4 in the first hollow cavity, the sealing component 3 can be blown with air to clean it, thereby preventing some materials from adhering to the surface of the sealing component 3 during discharge, causing gaps to form between the sealing component 3 and the discharge port 101, which would prevent the discharge port 101 from being sealed. This would cause some materials to fall through the gaps when the mixing component 1 mixes materials again, affecting the material ratio; the cleaning component 4 has good compatibility with the discharge component 2 and is easy and quick to install.

[0047] The material used is a lithium battery cathode material, and the cleaning gas is compressed air. As an alternative implementation, the material can be other materials that require mixing; this is not a limitation. Similarly, the cleaning gas can be helium or nitrogen, etc.; this is not a limitation either.

[0048] like Figure 5 As shown, in one embodiment, both the outlet 101 of the mixing component 1 and the sealing component 3 have circular cross-sections. When the sealing component 3 extends into the outlet 101 and abuts against the inner wall of the outlet 101, the sealing component 3 forms a closed state, and the materials are mixed; when the sealing component 3 is removed from the outlet 101, the sealing component 3 forms an open state, and the materials are discharged. As an alternative implementation, the cross-sections of the outlet 101 and the sealing component 3 can also be arc-shaped or square, and no further restrictions are imposed here.

The cleaning component 4 is made of stainless steel. By making the cleaning component 4 annular and disposed on the outer periphery of the sealing component 3, it can be adapted to the shape of the sealing component 3, resulting in a wider cleaning range, more thorough cleaning, and no missed areas. As an alternative implementation, the cleaning component 4 can also be made of PVC material or other non-magnetic materials; no further restrictions are imposed here.

By providing two inlets 401 and four vents 402, gas flow can be accelerated, thereby improving cleaning efficiency. As an alternative implementation, there may be one or three inlets 401, without further limitation. As an alternative implementation, there may be three or five vents 402, without further limitation.

There are two air outlets 7, one end of which is connected to the air storage component 5, and the other end is correspondingly positioned with the air inlet 401. Two first control components 6 are also provided. By providing the air outlets 7, the air storage component 5 does not need to be tightly attached to the air inlet 401, allowing for convenient adjustment of the position of the air storage component 5. As an alternative implementation, there may be one or three air outlets 7; no further limitations are imposed here.

[0054] like Figures 4-5As shown, in one embodiment, the gas storage component 5 is provided with an air inlet 8 for supplying clean gas to the gas storage component 5. There is one air inlet 8. Providing an air inlet 8 facilitates the supply of clean gas into the gas storage component 5. As an alternative implementation, there may also be two or three air inlets 8; no further limitation is made here.

[0055] like Figures 4-5 As shown, in one embodiment, a second control element 9 is connected between the gas storage component 5 and the air inlet component 8. The second control element 9 is a second solenoid valve, and one is provided. By providing the second control element 9, leakage of clean gas from the opening end of the air inlet component 8 can be prevented. As an alternative implementation, the second control element 9 can also be a second valve; no further limitations are imposed here.

Specifically, the drive assembly 10 includes a drive member 1001 fixedly mounted on the discharge member 2; and a transmission member 1002, one end of which is connected to the drive member 1001 and the other end of which is connected to the sealing member 3. The drive member 1001 is a hydraulic cylinder, and the transmission member 1002 is a connecting rod. By setting the drive assembly 10, the position of the sealing member 3 can be automatically adjusted, saving labor. As an alternative implementation, the transmission member 1002 can also be a lead screw, and the position of the sealing member 3 can be adjusted by driving the lead screw to rotate.

[0057] like Figure 5 As shown, in one embodiment, the drive member 1001 is connected to the third control member 11 for controlling the movement of the drive member 1001. The third control member 11 is a third solenoid valve. By setting the third control member 11, the movement of the drive member 1001 can be controlled according to the mixing state of the materials in the mixing chamber. As an alternative implementation, the third control member 11 can also be a switch; no further limitations are imposed here.

[0058] The working principle of the mixing device in this embodiment is as follows:

[0059] Step 1: Open the first solenoid valve to store compressed air into the air storage unit 5 through the air intake 8, and then close the first solenoid valve.

[0060] Step 2: After the materials in the mixing chamber are mixed, the third solenoid valve controls the movement of the hydraulic cylinder and drives the sealing component 3 to move to the open state.

[0061] Step 3: Open the second solenoid valve to introduce cleaning gas into the cleaning component 4 and blow it towards the sealing component 3 through the air outlet 402 to clean the material on the surface of the sealing component 3. Then close the second solenoid valve.
