Novel filtering and concentrating device and main reaction kettle device

Abstract

The invention discloses a novel filtering and concentrating device and a main reaction kettle device. The novel filtering and concentrating device comprises a cylinder body A, a cylinder body B, a gear motor A, a gear motor B, a stirring paddle A and a stirring paddle B, and further comprises a drain valve A, a drain valve B, a final concentrated product outlet A and a final concentrated product outlet B, wherein the gear motor A and the gear motor B are arranged at the top ends of the cylinder body A and the cylinder body B, the stirring paddle A and the stirring paddle B are arranged in theinner parts of the cylinder body A and the cylinder body B, the drain valve A and the drain valve B are arranged at the bottom ends of the cylinder body A and the cylinder body B; a nitrogen inlet, aregenerated liquid inlet and a spraying water inlet are arranged at the top end of the cylinder body A, an annular filter element is arranged on the inner wall of the cylinder body A, a back flushingport and a clear liquid outlet connected with the bottom part of the filter element and a filtered concentrated liquid outlet connected with a main reaction kettle are arranged on the side wall of thecylinder body A, a raw material feed port is arranged at the top end of the cylinder body B, an overflow port is arranged on the side wall of the cylinder body B and communicates with a middle tank,and the middle tank communicates with the top part of the filtering and concentrating device. The structure design of the novel filtering and concentrating device is more advanced and more reasonable,the mounting, dismounting and maintaining are simple and convenient, the problems of layering, shaking, sealing and the like of material liquid are effectively solved, and the filtering fineness is higher.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a novel filter concentration device and a main reactor device. Background technique [0002] The increase in shipments of power batteries in the future is mainly driven by the sales of passenger vehicles. It is expected that the demand for power batteries will continue to grow at a rate of 30-40% from 2018 to 2025. Ternary batteries will replace lithium iron phosphate batteries and become the mainstream of power battery shipments. The ternary precursor is the core raw material of the ternary battery, and the quality of its product directly determines the performance, safety and reliability of the ternary battery. There are many indicators to measure the quality of ternary precursors, among which three key indicators such as TD, SEM, and PSD are greatly affected by whether to use a filter concentrator. The ternary precursor products produced by the filter concentrator have good...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a more advanced and reasonable structural design, simple and convenient installation, disassembly and maintenance, which can effectively solve the problems of filter thickener material liquid stratification, shaking, sealing, etc., and the reliability and stability of the equipment are higher. Higher and lower operation and maintenance costs, higher filtration accuracy, higher interception efficiency, new type of filtration concentration device and main reactor device that can recover more valuable products
