[0035] like Figure 5 and Figure 7 As shown, the monitoring component 3 includes a temperature sensor 301, a support plate 302 and a control panel 303.

An auger 1204 is welded at the bottom of the rotating rod 1203. The rotation direction of the second motor 1201 is consistent with that of the threaded cover 1205. In this way, the second motor 1201 will not cause the threaded cover 1205 to loosen when it is working, and the second motor 1201 is used to work to drive the auger 1204 connected to the bottom of the rotating rod 1203. 4 rotates to transport the raw materials in the feeding tank 12 to the stirring tank 1. A feeding pipe 1202 is welded at the bottom center of the feeding tank 12. The peripheral side of the feeding pipe 1202 is provided with an external thread. The rotation direction of the second motor 1201 is consistent with the rotation direction of the feeding pipe 1202. The second motor 1201 will not cause the feeding tank 12 to loosen when working. The feeding pipe 1202 is connected to the threaded hole 11 through a thread. The second motor 1201 is a reduction motor, which can control the number of rotations of the auger 1204, thereby controlling the amount of raw materials in the feeding tank 12 entering the stirring tank 1, so as to achieve the purpose of quantitative feeding.

[0043] Specifically, when the high-speed dispersing and stirring device for lithium iron phosphate battery slurry is used: the first motor 202, the temperature sensor 301, the control panel 303 and the heating wire 403 are connected to the external power supply, and then the hydraulic cylinder 6 drives the support frame 5, the cover plate 201 and the high-speed stirring mechanism 2 to descend until the bottom of the sealing ring 10 fits with the top of the stirring tank 1, and then the first motor 202 is started, and the first motor 202 drives the cross rod 204, the second gear 205, the connecting rod 206, the third gear 207, the fourth gear 208, the extension rod 209 and the stirring rod 210 to rotate. At this time, the second gear 205, the connecting rod 206 and the third gear will rotate and revolve along the first gear 203, and the third gear 207 drives the fourth gear 20 8 rotates, thereby causing the extension rod 209 and the stirring rod 210 to rotate again along the central axis of the fourth gear 208, thereby increasing the contact area between the stirring rod 210 and the slurry, and greatly improving the stirring effect. Then the temperature sensor 301 will monitor the temperature inside the stirring tank 1 in real time, and can transmit the data to the display screen on the control panel 303, so that the user can understand the internal temperature of the stirring tank 1 and take corresponding measures in time. If the internal temperature of the stirring tank 1 is lower than 20-25°C, the heating wire 403 can be started through the control panel 303 at this time to increase the internal temperature of the stirring tank 1 to 20-25°C to ensure that the activity of the battery slurry is moderate, which is conducive to sufficient stirring and reaction. After the stirring is completed, the solenoid valve 9 is opened to facilitate the discharge of the slurry inside the stirring tank 1.

[0044] All technical features in this embodiment can be freely combined according to actual needs.
