Description

Technical Field

[0001] The utility model belongs to the technical field of lithium carbonate battery production, in particular to a lithium carbonate sedimentation and extraction device. Background Art

[0002] Lithium carbonate is an inorganic compound and a carbonate of lithium. It appears as colorless monoclinic crystals or white powder, slightly soluble in water and dilute acid, and insoluble in ethanol and acetone. The thermal stability of lithium carbonate is lower than that of carbonates of other elements in the same group in the periodic table, and it does not deliquesce in the air. In the industrial chain, the upstream of lithium carbonate is mainly lithium mining, including lithium extraction from salt lakes and lithium extraction from ores. The midstream is the refining of lithium carbonate, including the refining of industrial-grade lithium carbonate, high-purity lithium carbonate and battery-grade lithium carbonate. The downstream consumer areas are very broad, including lithium batteries for 3C products, power batteries, metal smelting, ceramic glass, catalysts, semiconductors, televisions, medicine, atomic energy industry and other fields. Especially in the fields of new energy vehicles and energy storage, lithium carbonate, as the core raw material of the lithium battery industry, plays an important role.

[0003] In the prior art, when lithium carbonate is extracted, the material in the liquid is mostly extracted by precipitation and sedimentation. During long-term use and observation, it is found that when lithium carbonate is currently produced, the lithium carbonate needs to be separated by a separation device after sedimentation. The use is inconvenient, the operation is cumbersome, the labor is increased, and the work efficiency during the production of lithium carbonate is affected.

[0024] Specific examples are given below.

[0025] like Figures 1 to 4 As shown, a lithium carbonate sedimentation and extraction device described in an embodiment of the utility model includes a sedimentation box 1; a feed port 11 is provided at the top of the sedimentation box 1; a liquid outlet 12 is provided at the bottom of the sedimentation box 1; a plurality of support components are provided in the middle of the sedimentation box 1; a filter paper 13 is provided on the top of the support component; when working, the staff introduces the flocculated lithium carbonate solution into the sedimentation box 1 from the feed port 11, at which time the filter paper 13 will filter the solution, and then separate the lithium carbonate in the solution, the lithium carbonate will remain in the support component and the filter paper 13, and the liquid will be guided out of the sedimentation box 1 from the liquid outlet 12. In this step, the lithium carbonate can be processed by providing the sedimentation box 1, the feed port 11 and the liquid outlet 12, and the lithium carbonate and the liquid can be separated by providing the support component and the filter paper 13, and then the lithium carbonate can be extracted. By setting the support component and the filter paper 13 as multiple layers, the flocculated lithium carbonate solution can be filtered multiple times, thereby improving the extraction effect of this device on lithium carbonate.

[0026] Further, such as Figures 1 to 4 As shown, the support assembly includes a sliding groove 2; the sliding grooves 2 are multiple and evenly opened on the side wall of the sedimentation box 1; a support rod 21 is fixedly connected inside the sedimentation box 1; the support rods 21 are multiple pairs and symmetrically distributed at the bottom of the sliding groove 2; a support frame 22 is provided in the middle of the sliding groove 2; a first support seat 23 is fixedly connected in the middle of the support frame 22; the filter paper 13 is arranged on the top of the first support seat 23; during work, when the staff needs to take out the extracted lithium carbonate from the inside of the sedimentation box 1, by removing the support frame 22 and the filter paper 13 from the sedimentation box The box 1 is pulled out, and the extracted lithium carbonate is taken out from the sedimentation box 1. This step can store the extracted lithium carbonate by providing filter paper 13, support frame 22 and first support seat 23, so as to facilitate the staff to collect and take out the extracted lithium carbonate, reduce the workload of the staff, and improve the work efficiency of the staff. By providing a sliding groove 2 and a support rod 21, the support frame 22 and the first support seat 23 can be supported when the support frame 22, the first support seat 23 and the filter paper 13 extract lithium carbonate.

[0027] Further, such as Figure 4 and Figure 5 As shown, the inner wall of the support frame 22 is fixedly connected to the second support seat 3; the second support seat 3 is multiple and evenly distributed on the inner wall of the support frame 22; the middle of the second support seat 3 is slidably connected to a sliding rod 31; the top of the sliding rod 31 is fixedly connected to a third support seat 32; a spring 33 is connected between the third support seat 32 and the second support seat 3; the bottom of the sliding rod 31 is ball-connected with a pressing block 34; when working, when the staff places the filter paper 13 on the top of the first support seat 23, the spring 33 will pull the third support seat 32, thereby causing the sliding rod 31 to slide along the second support seat 3, thereby causing the pressing block 34 It is fitted on the top of the filter paper 13 to press and fix the filter paper 13. In this step, a second support seat 3, a sliding rod 31, a third support seat 32 and a spring 33 are provided. After the staff places the filter paper 13 on the top of the first support seat 23, the filter paper 13 and the first support seat 23 can be fixed to reduce the displacement and offset of the filter paper 13 when the filter paper 13 extracts lithium carbonate.

[0028] Further, such as Figure 2 and Figure 3 As shown, a guide groove 4 is fixedly connected to the bottom of the inner wall of the sedimentation tank 1; the lowest point of the guide groove 4 corresponds to the liquid outlet 12; this step is provided with a guide groove 4, so that the extracted liquid can be guided, thereby reducing the liquid remaining at the bottom of the inner wall of the sedimentation tank 1, thereby reducing the liquid remaining at the bottom of the inner wall of the sedimentation tank 1, causing oxidation and rust of the sedimentation tank 1, and improving the service life of this device.

[0030] Further, such as Figure 1As shown, an observation window 6 is fixedly connected to the side wall of the sedimentation box 1; the observation window 6 is made of transparent material; this step allows the staff to more conveniently observe the extraction of lithium carbonate inside the sedimentation box 1 by providing the observation window 6, thereby reducing the workload of the staff when observing the inside of the sedimentation box 1, and further improving the work efficiency of the staff.

[0031] Working principle: During operation, the staff introduces the flocculated lithium carbonate solution into the sedimentation box 1 from the feed port 11. At this time, the filter paper 13 will filter the solution and separate the lithium carbonate in the solution. The lithium carbonate will remain in the support assembly and the filter paper 13, and the liquid will be discharged from the sedimentation box 1 from the liquid outlet 12. When the staff needs to take out the extracted lithium carbonate from the sedimentation box 1, they pull out the support frame 22 and the filter paper 13 from the sedimentation box 1 to take out the extracted lithium carbonate from the sedimentation box 1.
