As shown in fig. 1 to 5, the present application provides a reactor for a lithium battery with high cooling efficiency, which comprises a reaction kettle 1, a material pipeline 2 and a cover plate 3 arranged on the reaction container 1, and a cooling pipeline 4.

Firstly, raw materials (such as lithium iron phosphate) of the lithium battery anode material are respectively put into a ball mill for crushing, the proportion is adjusted according to production requirements after the crushing is finished, and the raw materials are mixed and then need to enter a reaction kettle 1 for roasting.

Reation kettle 1 includes

The material pipeline 2 comprises a feeding port 21 arranged at the upper end of the reaction vessel 11 and a discharging port 22 arranged at the lower end of the reaction vessel 11.

Before production, the outlet 22 is closed and the staff can feed the raw materials into the reaction vessel 11 through the inlet 21.

After the reaction is completed, the worker can open the discharge port 22, so that the reacted materials are discharged from the discharge port 22 by means of self gravity, and the effect of convenient discharging is achieved.

The cover plate 3 is used for sealing the feeding port 21, and after all the raw materials are added into the reaction vessel 11, the feeding port 21 is sealed through the cover plate 3, so that a closed space is formed inside the reaction vessel 11.

The driver 31 is fixedly installed on the upper side of the cover plate 3, in the present embodiment, the driver 31 is a motor, the output shaft of the driver 31 extends to the lower side of the cover plate 3 in a penetrating manner, the stirring shaft 32 is fixedly installed, and the stirring plates 33 are fixed on two sides of the lower end of the stirring shaft 32.
