Description

Technical Field

[0001] The utility model relates to the technical field of lithium precipitation and extraction, in particular to a precipitation reaction pool for wet extraction of lithium mica ore. Background Art

[0002] Lepidolite is one of the important minerals for lithium extraction. During the extraction process, it is usually necessary to continuously add the chemical agents required for the reaction to the sodium carbonate alkaline solution of the lepidolite. However, the traditional method of adding materials often results in uneven addition, which causes insufficient mixing of brine and alkaline solution, resulting in a high impurity content in the finished lithium carbonate.

[0003] Based on the above problems, the existing patent with publication number CN218393661U discloses a lithium precipitation device for lithium mica, which installs a disperser for uniformly dispersing brine in the reactor, so that the brine is evenly dispersed and added to the alkali solution, and the brine and the sodium carbonate alkali solution are fully mixed through a stirring device, so that the brine, sodium carbonate and lithium mica are fully reacted, thereby improving the quality of the finished lithium carbonate and reducing the impurity content of the finished lithium carbonate.

[0004] However, when implementing the above-mentioned lithium precipitation device for lithium mica, it was found that there were at least the following problems: during the extraction process, the spreader continuously added alkali solution and brine into the reactor, and the stirring rod of the stirring device drove the mixed solution of brine, sodium carbonate and lithium mica ore to mix. However, during the initial mixing of the lithium mica ore, the lithium mica ore contained some impurities, which made the lithium mica ore easily deposited at the bottom of the reactor, resulting in that some of the lithium mica ore deposited at the bottom of the reactor could not be stirred by the stirring rod, which led to insufficient mixing. The lithium carbonate deposited after sufficient reaction was easily mixed in some of the lithium mica ore that was not fully reacted, increasing the difficulty of subsequent extraction.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: a precipitation reaction tank for wet extraction of lithium mica ore, comprising a supporting platform 1, a mixing container 2, an electric push rod 3 and a stirring device 4, the electric push rod 3 is fixed on the supporting platform 1, and a supporting plate 5 is fixed at its output end, the mixing container 2 is fixed on the supporting plate 5, a plurality of supporting frames 6 surrounding the periphery of the mixing container 2 are provided on the supporting platform 1, the stirring device 4 is located on the top of the mixing container 2 and is fixed to the plurality of supporting frames 6, and the stirring end of the stirring device 4 extends into the mixing container 2 and is slidably connected to the mixing container 2.

[0023] The sedimentation reaction tank for wet extraction of lepidolite ore with the above structure is adopted. The electric push rod 3 pushes the support plate 5 to drive the mixing container 2 to move up and down. The stirring device 4 fixed on the support frame 6 stirs the lepidolite ore in the mixing container 2, so that the stirring device 4 can stir the bottom of the mixing container 2 during the stirring process, thereby solving the problem in the prior art that part of the lepidolite ore is easily deposited at the bottom of the reactor when lithium is extracted from the lepidolite ore, resulting in insufficient mixing.

[0024] In this embodiment, the stirring device 4 includes a motor 41 fixed to multiple support frames 6 and a T-shaped fixed tube 42. The fixed tube 42 is slidably connected to the mixing container 2, and one end of its single head is fixed to the support frame 6. The output end of the motor 41 is fixed to a rotating shaft 43, and the rotating shaft 43 is rotatably connected in the fixed tube 42. A gear 1 44 is provided at the bottom of the rotating shaft 43. One end of the double head of the fixed tube 42 is rotatably connected to an output shaft 45. The output shaft 45 is fixed with a gear 2 46 meshing with the gear at one end facing the gear. A plurality of stirring blades 47 are fixed to one end of the output shaft 45 protruding from the fixed tube 42. The rotating shaft 43 is driven to rotate by the output end of the motor 41 so that the gear 1 44 drives the stirring blades 47 on the two output shafts 45 to rotate in the opposite direction, so that during the mixing process, the stirring device 4 can more evenly mix and contact the lithium mica ore with brine and sodium carbonate, thereby increasing the stability of the chemical reaction between the lithium mica ore, brine and sodium carbonate when lithium is extracted from the lithium mica ore.

[0025] In this embodiment, sliding grooves 8 are provided on multiple support frames 6, and multiple fixed blocks 7 are fixed outside the mixing container 2. The multiple fixed blocks 7 are slidably connected in the sliding grooves 8.

The liquid spraying member 13 is fixed to the inner wall of the mixing container 2 and a plurality of spraying holes 14 are provided on the side facing the stirring device 4. By providing the annular liquid spraying member 13, the brine and sodium carbonate can be sprayed along the periphery of the stirring device 4, so that the brine and sodium carbonate can be quickly stirred by the stirring device 4, thereby increasing the mixing efficiency and the mixing stability.

[0029] Working principle: the mixed liquid of lithium mica ore and water is introduced into the mixing container 2, and brine and sodium carbonate are added to multiple feeding containers 10, and the brine and sodium carbonate are punched into the spray part 13 along the hose 11 through the booster pump 12, and sprayed toward the stirring blades 47. In this process, the output end of the motor 41 drives the rotating shaft 43 to rotate so that the gear 1 44 drives the stirring blades 47 on the two output shafts 45 to rotate in the opposite direction, and the electric push rod 3 pushes the support plate 5 to drive the mixing container 2 to move up and down, and the stirring device 4 fixed on the support frame 6 stirs the lithium mica ore in the mixing container 2. In this up and down lifting process, because a plurality of fixed blocks 7 slidably connected to the sliding groove 8 are provided, the mixing container 2 can be prevented from being offset and tilted. When the mixing stops, the electric push rod 3 is retracted to drive the mixing container 2 to move downward, and the support plate 5 is supported by the limit support column 9.
