Problems solved by technology

[0002] In order to reduce the introduction of magnetic foreign matter in the existing ternary precursor preparation process, stainless steel equipment is usually used to avoid or eliminate the use of copper and zinc parts, and each process is equipped with a pipeline iron remover for demagnetization. After drying and packaging, it passes through an electromagnetic remover Packaging, but the content of magnetic foreign matter in the ternary precursor produced is about 20ppb, and there is instability, and it is prone to abnormal magnetic foreign matter caused by equipment wear and tear, which affects product quality

Abstract

The invention discloses a production system and a production method of a ternary precursor, and belongs to the technical field of ternary precursors. The production system comprises reaction equipment, solid-liquid separation equipment, drying equipment and material mixing equipment which are connected in sequence, wherein a first wear-resistant coating is arranged on the inner wall of the reaction equipment; the drying equipment comprises a drying oven body, a carrier and a drying pan used for being contained on the carrier, the drying oven body is provided with a drying cavity, the carrier is detachably arranged in the drying cavity, and a second wear-resistant coating is arranged at the joint, used for being connected with the drying pan, of the carrier; a third wear-resistant coating is arranged on the inner wall of the mixing equipment; and the solid-liquid separation equipment is provided with a rotary drum, and a fourth wear-resistant coating is arranged on the inner wall of the rotary drum. Compared with existing equipment, the production system has the advantage that pollution caused by friction of metal parts is reduced by arranging the wear-resistant coating. By adopting the production system to produce the ternary precursor, the content of magnetic foreign matter in the ternary precursor product can be reduced.

Description

technical field [0001] The present invention relates to the technical field of ternary precursors, in particular to a production system and production method of ternary precursors. Background technique [0002] In order to reduce the introduction of magnetic foreign matter in the existing ternary precursor preparation process, stainless steel equipment is usually used to avoid or eliminate the use of copper and zinc parts, and each process is equipped with a pipeline iron remover for demagnetization. After drying and packaging, it passes through an electromagnetic iron remover It is packaged, but the content of magnetic foreign matter in the produced ternary precursor is about 20ppb, and there is instability, and it is prone to equipment wear and tear to cause abnormal magnetic foreign matter, which affects product quality. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] One of the objectives of the present invention include...
