Fig. 7 is a schematic diagram of a second cross-sectional structure of a mounting portion and a tank body of a stirring tank according to an embodiment of the present application.

In a first aspect, referring to fig. 1-7, an embodiment of the present application provides a stirring tank 10, the stirring tank 10 including a tank body 100, a stirring member 200, and a spoiler 300.

Specifically, referring to fig. 1 to 7, the can body 100 has a receiving chamber 110, and the receiving chamber 110 includes a central region 111 communicating with each other and an edge region 112 located on the outer peripheral side of the central region 111. The receiving chamber 110 may be used to receive a medium to be stirred.

Thus, when the stirring member 200 rotates, the main body 310 can change the orientation of the lithium iron manganese phosphate particles to prevent the lithium iron manganese phosphate particles from rotating near the inner wall 120 of the tank body, thereby preventing the lithium iron manganese phosphate particles from rotating to form vortex so as to ensure uniform distribution of lithium iron manganese phosphate particles with different sizes.

The main body 310 is connected to the tank 100 by the mounting portion 320, and the main body 310 and the tank 100 together define an annular space communicating with the accommodation chamber 110. In this way, the lithium iron manganese phosphate particles can penetrate through the annular region, so that part of the lithium iron manganese phosphate particles can be prevented from gathering at the gap between the main body part 310 and the tank body 100, and the lithium iron manganese phosphate particles with different sizes are ensured to be uniformly distributed.

It should be noted that the size of the annular space needs to be larger than any lithium iron manganese phosphate particles, and the lithium iron manganese phosphate particles with the largest size can also penetrate the annular space, so that all lithium iron manganese phosphate particles can be ensured to penetrate the annular space.

Through the above arrangement, when the stirring machine stirs the lithium manganese iron phosphate particles, the main body portion 310 can change the orientation of the lithium manganese iron phosphate particles so as to prevent the lithium manganese iron phosphate particles from rotating near the inner wall 120 of the tank body, and further prevent the lithium manganese iron phosphate particles from rotating to form vortex, so as to ensure that the lithium manganese iron phosphate particles with different sizes are uniformly distributed in the accommodating cavity 110; the annular space formed by the main body 310 and the tank 100 can be penetrated by the lithium iron manganese phosphate particles, so that the lithium iron manganese phosphate particles can penetrate through the annular space after contacting with the main body 310, so as to avoid aggregation at the gap between the main body 310 and the tank 100, and further ensure that the lithium iron manganese phosphate particles with different sizes are uniformly distributed.

The other two mounting portions 320 may be disposed at a distance from each other.

In this way, the contact area between the main body 310 and the can inner wall 120 is large, the connection tightness between the main body 310 and the can 100 is good, and the main body 310 can be fixed to the can inner wall 120 more stably.

Or the number of the main body portions 310 is plural, and the plurality of main body portions 310 are arranged in parallel to each other along the extending direction intersecting the main body portions 310.

The specific number of the body parts 310 is not limited to the above example, and may be adjusted according to the size of the can 100.

Through the arrangement, the plurality of main body parts 310 can be distributed on the inner wall 120 of the tank body, the area of the outer surface of the main body parts 310 is larger, the possibility that the main body parts 310 are contacted with the lithium manganese iron phosphate particles is larger, the orientation of the lithium manganese iron phosphate particles can be changed more conveniently, the lithium manganese iron phosphate particles are prevented from rotating nearby the inner wall 120 of the tank body, and further, the lithium manganese iron phosphate particles are prevented from rotating to form vortex, so that the lithium manganese iron phosphate particles with different sizes are uniformly distributed.

As an alternative embodiment, referring to fig. 1 to 4, the main body portion 310 extends along a spiral line, the spiral axis of which coincides with the rotation axis of the stirring member 200, i.e., extends in the second direction Y.
