Auxiliary device for facilitating preparation of layered double hydroxide

The invention belongs to the technical field of preparation of layered double hydroxide, and particularly relates to an auxiliary device for facilitating preparation of layered double hydroxide. According to the scheme, the auxiliary device comprises a box body, wherein a separating mechanism of a circular structure is arranged on the inner ring of the box body, an outer ring grinding plate of an annular structure fixedly connected with the inner side wall of the box body is installed at the top of the separating mechanism, an inner ring grinding assembly is installed on the inner ring of the outer ring grinding plate, and the outer ring of the top of the inner ring grinding assembly is slidably sleeved with an outer side isolation sleeve fixedly connected with the inner side wall of the top of the box body. According to the auxiliary device, the grinding precision of raw materials can be adjusted according to needs, the grinding plate can be rapidly cooled, heat generated by friction is discharged in the grinding process, the situation that the properties of the raw materials are damaged due to the fact that the temperature of the grinding plate is increased in the grinding process is avoided, meanwhile, the situation that the hardness of the grinding plate is reduced due to the fact that the grinding plate is annealed due to the temperature rise is avoided, the grinding effect is reduced, and the grinding efficiency and quality of the raw materials are improved.
