Description

Technical Field

[0001] This utility model relates to the field of lithium extraction technology from ore roasting, specifically a continuous roasting device for lepidolite. Background Technology

[0002] The recovery of lithium from ores usually involves grinding the ore containing lepidolite into powder, followed by high-temperature roasting, and then water leaching to extract lithium from the roasted ore powder. However, in the actual roasting process, due to the presence of large clay lumps and mica particles in the ore, and the frequent occurrence of ore agglomeration during roasting, while the internal ore is not roasted sufficiently, the subsequent lithium extraction yield is affected.

[0003] Publication No. CN214937718U discloses a lithium mica roasting apparatus. It employs a dispersing device and a stirring device sequentially arranged in a mixing chamber. The dispersing device breaks up large lumps of ore, effectively preventing ore agglomeration, while the stirring device thoroughly mixes the ore, resulting in a more uniform ore powder texture, thus enabling complete roasting. Several ore extrusion devices are installed between the bottom of the mixing chamber and the top of the roasting chamber, allowing the ore to be extruded into the roasting chamber in batches and quantities, preventing a large amount of ore from entering the roasting chamber at once. This ensures that the batches of ore in the roasting chamber are fully roasted. However, this patent still has the following problems in practical use:

[0004] Although the lithium mica roasting device breaks down large particles by setting up a dispersing device, the ore re-agglomerates when it is extruded through the extrusion device, which is not conducive to the uniform roasting of the ore. At the same time, there is no relevant structure to limit the ore during the roasting process, which causes some ore to fall into the ore cooling device without being roasted, thus affecting the roasting effect.

[0005] Therefore, a continuous calcination apparatus for lepidolite is proposed to solve the problems mentioned above. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This continuous roasting device for lepidolite can evenly divide the internal space of the quantitative feeding box into several portions through the partition baffle. Each space can store a certain amount of ore. During feeding, a certain amount of ore can be transported to the rotary kiln, thereby realizing the function of quantitative feeding. Utilizing the meshing connection between the dispersing main gear, the dispersing driven gear, and the meshing gear ring, not only can the rotation of the dispersing driven gear be realized, but also its revolution can be realized.

[0020] 1. By setting up a roasting mechanism, not only can the feeding motor drive the first rotating disk to rotate, but the feeding rotating rod can also drive the second rotating disk to rotate.

[0021] 2. By setting up a mixing and dispersing mechanism, the ore can fall from the feed hopper into the dispersing box through the feed pipe.
