Description

Technical Field

[0001] The utility model relates to the technical field of lithium carbonate production, in particular to a drying device used for lithium carbonate production. Background Art

[0002] Lithium carbonate is an inorganic compound that appears as colorless monoclinic crystals or white powder. General industrial salt lake brine is processed through multiple steps to produce lithium carbonate. The last step is the drying of lithium carbonate. During the use of drying equipment for lithium carbonate production, some lithium carbonate forms large lumps due to the direct hot air drying method, which affects its use. In addition, the traditional stirring method cannot turn the lithium carbonate material well, resulting in incomplete drying.

[0003] The publication (announcement) number is CN219301210U, which discloses a drying device for lithium carbonate production, including: a drying box, the drying box is fixed on the base through a bracket, a feed port is provided at the upper part of the drying box, a hot air duct is provided at each of the four corners of the drying box, a motor is provided on one side of the drying box, the output shaft of the motor drives the rotating shaft in the middle of the drying box to rotate, the rotating shaft is provided with stirring blades, and the stirring blades are staggered on the rotating shaft; a funnel-shaped unloading part is provided at the lower part of the drying box, a vibrating screen is provided in the unloading part, and a small vibrating motor is provided on the vibrating screen. This device adopts a multi-angle hot air passing method, combined with spiral stirring, to break up the agglomerated lithium carbonate for sufficient drying, and can screen the lithium carbonate that meets the requirements with the vibrating screen.

[0004] Although the above scheme avoids the agglomeration of lithium carbonate and performs multi-angle drying, the multi-angle drying method in which hot air ducts are arranged at the four corners of the drying box requires the assembly of multiple sets of hot air preparation and conveying components. The operating cost of the drying parts of the equipment is high, and some of the broken lithium carbonate will be directly screened out and fall out of the drying box, and a stable drying effect cannot be obtained. It is difficult for the equipment to fully guarantee the drying effect of lithium carbonate. For this reason, we propose a drying device for lithium carbonate production. Utility Model Content
