In the embodiment of the present invention, the number of the ball valves 40 is 2, which are respectively a first ball valve 41 and a second ball valve 42. The first ball valve 41 is disposed in the first pipe 31, a contact position between an inner wall of the first pipe 31 and the first ball valve 41 and a surface of the first ball valve 41 are coated with a coating, and the first ball valve 41 can rotate to enable the first pipe 31 to be in a connected state or a disconnected state; the second ball valve 42 is disposed in the second pipe 32, a coating is coated on a contact position between an inner wall of the second pipe 32 and the second ball valve 42 and a surface of the second ball valve 42, and the second ball valve 42 can rotate to enable the second pipe 32 to be in a connected state or a disconnected state.

The weighing module 51 detects the weight of the lithium iron phosphate positive electrode material in the material receiving bin 50 in real time, and sends weight information to the data processing module 62. When the data processing module 62 determines that the weight information reaches the preset weight value of the current material collecting operation, an instruction is sent to the control module 61, and the control module 61 controls the first ball valve 41 to rotate to enable the first pipeline 31 to be in a disconnected state after receiving the instruction. At this time, the material collecting operation is completed, and the data processing module 62 synchronously records the weight of the lithium iron phosphate positive electrode material conveyed this time and the thickness change of the coating of the first ball valve 41. When the next material receiving operation is performed, the data processing module 62 determines in advance whether the ball valve 40 needs to be replaced according to the weight of the lithium iron phosphate positive electrode material conveyed by the material receiving operation.
In addition, in the material receiving process, when the data processing module 62 receives that the coating thickness information is smaller than the preset coating thickness preset value, the data processing module 62 determines that the ball valve 40 needs to be replaced and sends an instruction to the control module 61, after receiving the instruction, the control module 61 closes the first baffle 311 and rotates the first ball valve 41 to make the first pipeline 31 in a disconnected state, opens the second baffle 321 and rotates the second ball valve 42 to make the second pipeline 32 in a connected state, and the lithium iron phosphate anode material can pass through the second pipeline 32 and enter the material receiving bin 50. At this time, the first ball valve 41 can be conveniently replaced, so that the production line of the lithium iron phosphate anode material cannot stop production due to replacement of the first ball valve 41, and the production efficiency of the lithium iron phosphate anode material is improved.
