A precursor solution preparation and drying device

Abstract

The invention is applicable to the technical field of lithium batteries, and provides a precursor solution preparation and drying device, including a distribution pool, a reaction pool located below the distribution pool, and a recovery pool located on the right side of the reaction pool, and the tops of the distribution pools are arranged side by side, etc. There are six liquid inlet pipes, and the bottom end of each liquid inlet pipe is provided with an electric control valve, a piston is vertically arranged in the distribution pool, and a piston propulsion device for pushing the piston to move left and right is provided on the right side of the distribution pool , the reaction tank is provided with a briquetting block and a lifting device to control the up and down movement of the briquetting block, a plurality of drainage tubes are vertically penetrated through the briquetting block, and a heating plate corresponding to the briquetting block is arranged at the bottom of the reaction pool, so There are conduits connected between the left and right bottoms of the distribution pool and the reaction pool, and the side walls of the reaction pool are provided with lye inlet pipes. The device combines preparation and drying into one device, which is helpful for industrial manufacturing and improves work efficiency.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a precursor solution preparation and drying device. Background technique [0002] The precursor is an important batch material for the manufacture of lithium battery cathode materials. The commonly used manufacturing method is mainly the precipitation method. The nickel, cobalt, and manganese solutions are precipitated according to the ratio of 2:2:6 to obtain the precursor and the precursor precipitate. It needs to be dried afterwards. [0003] In the actual operation process, two devices are required for the precipitation reaction and drying process. First, the precipitation reaction is carried out in the reaction device to obtain the precursor precipitate, and then the precursor precipitate is transported to the drying device for drying. This operation process is cumbersome. , the work efficiency is not high. Contents of the invention [0004] In view of the abov...
