Efficient and intelligent reaction crystallization device

Abstract

The invention discloses a device capable of controlling reaction crystallization process efficiently, intelligently and accurately. The device comprises a main device reaction kettle, a constant temperature water bath device is mounted on the outer side of the main device, a feeding device is mounted on the upper portion of the main device, a stirring device, a pH electrode and a conducting electrode are mounted on the upper portion of the main device; the constant temperature water bath device, the feeding device, the stirring device, the pH electrode, the conducting electrode and the like are connected with a programmable logic controller PLC automatic control system to realize automatic intelligent control, simultaneously particle sizes of the products are in real-time monitored by a on-line particle size measurement system. The device is simple and clear in whole structure, fully automatic measurement, feedback and control during the reaction crystallization process are realized, manual operating cost and manual operating errors are reduced to make the reaction crystallization process perform in a setting reaction condition all the time, accordingly quality and stability of thedesired products are guaranteed.

Description

technical field [0001] The invention relates to the field of automatic control of chemical reaction crystallization, in particular to an efficient and intelligent reaction crystallization equipment. It can be used for quality control of reaction crystallization in chemical industry, advanced materials and pharmaceutical products. Background technique [0002] The core part of lithium-ion batteries is the cathode material. However, the current cathode material precursors have problems such as small crystal tap density, wide particle size distribution, defective morphology, and unstable quality during the large-scale preparation process. Precise on-line monitoring, Automatically adjust the reaction conditions such as feeding speed, temperature, pH, conductivity, and stirring speed in the reaction system to achieve precise control of the reaction crystallization process of the cathode material precursor. [0003] Such as the patent CN105183026B, the invention name is: an autom...
