Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing devices, in particular to a reaction kettle for manufacturing battery positive electrode materials. Background Art

[0002] In the production process of lithium-ion battery positive electrode materials, a solution containing an acidic material and a solution containing an alkaline material react in a reactor to form cobalt-nickel-manganese hydroxide powder. The mixing and dispersion of the acidic and alkaline solutions is the most important step in the entire production process, affecting product quality by more than 30%. The uniformity of the mixing and dispersion directly affects the quality of the lithium-ion battery. Therefore, a reactor for manufacturing battery positive electrode materials is required.

[0003] According to a reactor for manufacturing positive electrode materials for lithium batteries disclosed on the patent website (authorization announcement number: CN210332658 U), "The utility model discloses a reactor for manufacturing positive electrode materials for lithium batteries, comprising a reactor body and a cover body fixedly connected to the reactor body by a flange, the reactor body is provided with a first stirring device and a second stirring device used in conjunction with each other, a first feed pipe is passed through and fixed on the left wall of the reactor body, the first feed pipe is connected to and fixed with a vertically distributed first delivery pipe at one end in the reactor body, a plurality of first feed ports are opened on the right side wall of the first delivery pipe, and a second feed pipe, a second delivery pipe and a plurality of second feed ports are fixed on the right wall of the reactor body in a mirror-symmetrical manner. Acidic solution and alkaline solution enter the reactor body through the plurality of first feed ports and the plurality of second feed ports respectively, so that the solution containing the acidic material and the solution containing the alkaline material are dispersed when entering the reactor, so that the concentration of the reactants is evenly distributed, and then the first stirring device and the second stirring device are used for stirring, and the mixing and dispersion reaction efficiency is high."

[0004] In response to the above description, the applicant believes that the following problems exist: when the device is in use, multiple first feed ports and multiple second feed ports can disperse the solution containing acidic materials and the solution containing alkaline materials when entering the reactor, so that the concentration of the reactants is evenly distributed. The device can only facilitate the entry of the solution into the reactor. When other granular raw materials need to be added, the flange in the cover body needs to be removed and then the material needs to be added. Subsequently, the cover body needs to be fixed to the top of the reactor again through the flange. The operation is very cumbersome and not conducive to production. Utility Model Content
