[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0026] A vacuum dispersion mixing vessel for lithium battery electrode slurry includes a tank body 2 and a stirring component 3 for stirring the electrode slurry. The tank body 2 has a cavity for storing the electrode slurry. The stirring component 3 includes a stirring part and a second motor 35. The stirring part is rotatably connected to the tank body 2. Part of the stirring part is inside the cavity, and the top of the stirring part extends to the outside of the tank body 2. The top of the stirring part is open to form a slot 34. A top plate 27 is fixedly connected to the top of the tank body 2. The top plate 27 has a positioning hole 211 and two insertion holes 28. The positioning hole 211 is located between the two insertion holes 28. The output end of the second motor 35 is connected to a cross rod 36, and two insertion rods 37 are symmetrically fixedly connected to the bottom of the second motor 35. The cross rod 36 is located between the two insertion rods 37. The cross rod 36 matches the slot 34, and the insertion rods 37 match the insertion holes 28.

[0027] With the above technical solution, when personnel need to disperse and stir the lithium battery electrode slurry, the lithium battery electrode slurry is added into the cavity inside the tank 2. After the lithium battery electrode slurry is added, the second motor 35 is placed above the tank 2, so that the cross rod 36 on the second motor 35 passes through the positioning hole 211 and is inserted into the slot 34 at the top of the stirring part. At the same time, the insertion rod 37 on the second motor 35 is inserted into the insertion hole 28 on the top plate 27. The operation of the second motor 35 drives the cross rod 36 to rotate, which in turn drives the stirring part to rotate. The stirring part stirs and disperses the lithium battery electrode slurry inside the cavity. When personnel need to replace the second motor 35, the second motor 35 is pulled, which moves the cross rod 36, causing the cross rod 36 to separate from the slot 34 on the stirring part and the insertion rod 37 to separate from the insertion hole 28. The second motor 35 can then be removed for replacement.

[0028] After the insertion rod 37 is inserted into the locking hole 29, to prevent the insertion rod 37 from accidentally falling out, Figures 1-5 As shown, a flexible locking head 38 is installed on one side of the insertion rod 37, and a locking hole 29 is formed on one side of the top plate 27. The locking hole 29 is connected to the insertion hole 28, and the locking hole 29 matches the flexible locking head 38.

[0029] In this embodiment, when the insertion rod 37 is connected to the locking hole 29, the elastic locking head 38 on the insertion rod 37 engages with the locking hole 29 on the top plate 27, making the connection between the insertion rod 37 and the locking hole 29 more secure and preventing the second motor 35 from falling off accidentally.

[0030] Specifically, in one embodiment, regarding the aforementioned tank component 2, as... Figures 1-4As shown, the tank body 2 includes a tank body 21, a drain pipe 213 is fixedly connected to the bottom of the tank body 21, and a detachable top cover 24 is installed on the top of the tank body 21. A valve 212 is installed on the drain pipe 213. A buckle 22 is rotatably connected to one side of the tank body 21, and a groove 25 matching the buckle 22 is formed inward on the top cover 24.

[0031] In this embodiment, when personnel need to add lithium battery electrode slurry, they pull the buckle 22 to rotate around the tank body 21, thereby separating the buckle 22 from the slot 25 on the top cover 24, removing the top cover 24, and then adding the lithium battery electrode slurry into the tank body 21. After adding the lithium battery electrode slurry, the top cover 24 is placed on top of the tank body 21. After the top cover 24 is placed, the buckle 22 is pulled to rotate around the tank body 21, thereby engaging the buckle 22 with the slot 25 on the top cover 24, thus fixing the top cover 24 on top of the tank body 21, so that the subsequent stirring and dispersing of the lithium battery electrode slurry can be carried out. When personnel need to discharge the stirred and dispersed lithium battery electrode slurry, the valve 212 is opened, and the stirred and dispersed lithium battery electrode slurry is discharged through the drain pipe 213.

[0032] When personnel need to release the gas inside tank 21, such as Figures 1-4 As shown, a gas extraction pipe 210 for extracting gas is fixedly connected to the top of the top cover 24, and the gas extraction pipe 210 is connected to the inside of the tank body 21.

[0033] In this embodiment, when the stirring part stirs and disperses the lithium battery electrode slurry, the air inlet of the vacuum equipment is connected to the air extraction pipe 210. By operating the vacuum equipment, the gas inside the tank 21 is extracted through the air extraction pipe 210, thereby reducing the gas pressure inside the tank 21 and making the inside of the tank 21 relatively vacuum, making the stirring and dispersion of the lithium battery electrode slurry more efficient.

[0034] When the device discharges slurry, in order to ensure more thorough discharge, such as Figure 4 As shown, a guide slope 23 is formed at the bottom of the cavity, and the horizontal height of the guide slope 23 on the side near the drain pipe 213 is lower than the horizontal height on the other side.

[0035] In this embodiment, when the lithium battery electrode slurry is discharged from the drain pipe 213, the guide slope 23 facilitates the discharge of the lithium battery electrode slurry.

[0036] Regarding the stirring part mentioned above, as Figures 1-5 As shown, the top cover 24 has a through hole 26. The stirring part includes a connecting shaft 32, which is rotatably connected to the inside of the through hole 26. A slot 34 is formed on the top of the connecting shaft 32, and a dispersing disk 31 is fixedly connected to the circumference of the connecting shaft 32. The dispersing disk 31 is located inside the cavity.

[0037] In this embodiment, when the cross rod 36 is inserted into the slot 34 on the connecting shaft 32, the second motor 35 works to drive the cross rod 36 to rotate, which in turn drives the connecting shaft 32 to rotate, which in turn drives the dispersing disk 31 to rotate, thereby dispersing the lithium battery electrode slurry.

[0038] In order to thoroughly mix the slurry, such as Figure 5 As shown, multiple stirring rods 33 are fixedly connected in a ring array on the circumference of the connecting shaft 32, and the stirring rods 33 are located inside the cavity.

[0039] In this embodiment, when the connecting shaft 32 rotates, the connecting shaft 32 will synchronously drive the stirring rod 33 to rotate, and the stirring rod 33 will stir the lithium battery electrode slurry.

[0040] Furthermore, in this invention, the stirring vessel also includes a support member 1, on which a support cavity is formed, and the tank body 21 is rotatably connected to the inside of the support cavity.

[0041] In this embodiment, the tank 21 is supported by the support cavity on the support member 1. When personnel need to remove the second motor 35, the tank 21 is rotated around the support cavity on the support member 1 so that the second motor 35 is rotated to a lower position, making it easier for personnel to remove the second motor 35 for inspection and maintenance.

[0042] Specifically, in one embodiment, regarding the aforementioned support member 1, as... Figures 1-4 As shown, the support member 1 includes two symmetrically arranged support plates 11, and each of the two support plates 11 is rotatably connected to a rotating shaft 13 on its opposite side. The tank body 21 is fixedly connected between the two rotating shafts 13.

[0043] In this embodiment, the tank 21 is supported by the rotating shaft 13 on the support plate 11. When personnel need to rotate the tank 21, they pull the tank 21 so that the tank 21 rotates around the support plate 11 via the rotating shaft 13, thereby allowing the second motor 35 to rotate to a lower position, making the second motor 35 easy to disassemble and maintain.

[0044] Furthermore, regarding how the rotating shaft 13 rotates in this utility model, as follows: Figures 1-4 As shown, a first motor 12 is fixedly connected to one of the support plates 11, and the output end of the first motor 12 is connected to one of the rotating shafts 13.

[0045] In this embodiment, when it is necessary to drive the rotating shaft 13 to rotate, the first motor 12 works to drive the rotating shaft 13 to rotate, so that the rotating shaft 13 drives the tank body 21 to rotate.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
