They are an ideal power source for new energy vehicles, mobile phones, laptops, digital cameras, video cameras, and other electronic products. Lithium carbonate is a key component of lithium-ion batteries and serves as a raw material for their manufacture.

[0003] Lithium carbonate is a white powder that appears as fragile, porous crystals with acidic properties. During the production process for lithium-ion batteries, impurities adsorbed on the surface of the lithium carbonate are removed through agitation and washing to improve its purity, reduce its impurity content, and increase the drying rate of semi-packaged lithium carbonate.

[0004] In the production process of battery-grade lithium carbonate, after the crude lithium carbonate is produced, it is often stirred and washed to remove the mother liquor adsorbed on the surface of the lithium carbonate and various soluble impurities adsorbed on the surface, such as various carbonate and sulfate impurities of potassium, sodium, calcium, magnesium, etc. In order to ensure a good impurity removal effect and reduce the dissolution of lithium carbonate (taking advantage of the property that the solubility of lithium carbonate decreases with increasing temperature), desalted water is generally added to the washing tank with high-speed stirring and heating.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figure 1 、 Figure 2 As shown, according to an embodiment of the present invention, a washing device for lithium carbonate production includes a bracket 1, a first tank body 2, a separation mechanism 7 and a cleaning mechanism 6, the first tank body 2 is arranged on the bracket 1, the separation mechanism 7 is arranged in the first tank body 2, and the cleaning mechanism 6 is arranged on the top of the first tank body 2, the cleaning mechanism 6 includes a second tank body 61, a feeding pipe 64, a liquid inlet assembly, a stirring mechanism and a receiving platform 611, the second tank body 61 is connected to the first tank body 2, the feeding pipe 64 and the liquid inlet assembly are both connected to the second tank body 61, and the connecting position is located above the receiving platform 611, the receiving platform 611 can be flipped and arranged in the second tank body 61, the stirring mechanism is arranged corresponding to the receiving platform 611, and the bottom surface shape of the stirring mechanism is adapted to the receiving surface shape of the receiving platform 611.

[0028] In the above technical solution, a bracket 1 is provided to support the washing device for lithium carbonate production, and the posture of the washing device is restricted to prevent the washing device from rolling; the first tank body 2 is used to accommodate the separation mechanism 7 and the material after cleaning by the cleaning mechanism 6, and provides a working space for the separation mechanism 7 to achieve solid-liquid separation of the cleaned material; the setting of the separation mechanism 7 can separate the solid-liquid mixed material and the cleaning liquid after cleaning by the cleaning mechanism 6; the cleaning mechanism 6 can fully stir and clean the material, and at the same time prevent the material from adhering to the inner surface of the device and the bottom of the second tank body 61, thereby further improving the washing effect; the second tank body 61 accommodates the stirring mechanism, the receiving platform 611 and the material, and is externally connected to the first tank body 2, the feeding pipe 64 and the liquid inlet component, providing a working space for the stirring and cleaning related structures to fully stir and clean the material; the feeding pipe 64 is connected to the outside and the second tank body 61, for adding materials to be cleaned into the washing device; the liquid inlet component is mainly used for adding cleaning liquid into the second tank body 61, and cooperates with the stirring mechanism to achieve the effect of cleaning the materials; the stirring mechanism rotates in the second tank body 61, stirring the materials and the cleaning liquid to fully contact and mix to achieve cleaning of the materials; the receiving platform 611 is used to receive the materials added to the second tank body 61, to avoid the materials from accumulating at the bottom of the second tank body 61 and not being able to be fully stirred by the stirring mechanism, and at the same time, by setting the bottom surface of the stirring mechanism to a shape compatible with the receiving surface of the receiving platform 611, to avoid the materials from adhering to the surface of the receiving platform 611 and not being able to be fully stirred by the stirring mechanism; after the materials received by the receiving platform 611 are fully cleaned, the currently cleaned materials are released by flipping the receiving platform 611 to enter the next processing step, and then the receiving platform 611 returns to its initial state to continue to receive the next batch of newly added materials.

[0029] like Figure 2 、 Figure 3 As shown, in one embodiment, the receiving surface of the receiving platform 611 forms a groove, and the stirring mechanism includes a stirring block 615 and a convex strip 616 arranged at the bottom of the stirring block 615, and the bottom surface shape of the convex strip 616 facing the groove is adapted to the concave shape of the groove.

[0030] In the above technical solution, the stirring block 615 and the convex strip 616 arranged at the bottom of the stirring block 615 mainly play the role of stirring. The bottom surface shape of the convex strip 616 facing the groove is set to a concave shape adapted to the receiving surface of the receiving platform 611, which can ensure that the convex strip 616 scrapes up the material adhering to the receiving surface of the receiving platform 611, so that every material can be stirred, thereby improving the stirring and washing effect of the material, and avoiding the problem that the material adhering to the bottom of the receiving platform 611 cannot be fully stirred.

[0031] like Figure 3As shown, in one embodiment, the stirring mechanism also includes a second motor 612, a rotating rod 613 and a stirring rod 614, the second motor 612 is arranged on the top of the second tank body 61, the rotating rod 613 is connected between the second motor 612 and the stirring block 615, and the stirring rod 614 is arranged on the periphery of the rotating rod 613 and extends laterally along the rotating rod 613.

[0032] In the above technical solution, the second motor 612 provides power to the stirring mechanism, which drives the rotating rod 613 to cause the stirring rod 614 and the stirring block 615 to rotate around the rotating rod 613, thereby stirring the material. The stirring rod 614 is located in the middle and lower part of the rotating rod 613, and is used to fully stir the material located above the receiving platform 611.

[0033] like Figure 3 As shown, in one embodiment, the bottom of the stirring block 615 is convex arc-shaped, and there are multiple convex strips 616. The multiple convex strips 616 are arranged at intervals along the circumference of the stirring block 615. The concave surface of the groove is concave arc-shaped, and the bottom surface of the convex strips 616 facing the concave surface is an arc surface that is adapted to the shape of the concave surface.

[0034] A plurality of convex strips 616 are used to form an arc surface that is compatible with the concave arc surface. On the one hand, the convex strips 616 can be more compatible with the surface shape of the receiving platform 611, and there can be a smaller gap between the convex strips 616 and the surface of the receiving platform 611 during the stirring process, thereby reducing the thickness of the material that can adhere to the surface of the receiving platform 611 and more fully scraping off the material adhered to the surface of the receiving platform 611. On the other hand, the plurality of convex strips 616 can also increase the stirring intensity of the material deposited on the surface of the receiving platform, further improving the stirring and cleaning effect.

[0035] like Figure 2 As shown, in one embodiment, two mounting plates 65 are spaced apart in the up and down directions on the side wall of the second tank body 61, and a rotating shaft 67 is rotatably provided between the two mounting plates 65. A first motor 66 is provided on one of the mounting plates 65, and the first motor 66 is driven and connected to the rotating shaft 67. A first bevel gear 68 is fixedly sleeved on the outer wall of the rotating shaft 67. A rotating rod 610 is rotatably provided on the side wall of the second tank body 61, and a first end of the rotating rod 610 is fixedly connected to the receiving platform 611. A second bevel gear 69 is provided on the second end of the rotating rod 610, and the first bevel gear 68 and the second bevel gear 69 are engaged.

[0036] In the above technical solution, the first motor 66 provides power to drive the rotating shaft 67 to rotate, thereby driving the first bevel gear 68 sleeved on the rotating shaft 67 and the second bevel gear 69 engaged with the first bevel gear 68, and then transmitting the rotational motion of the vertical rotating shaft 67 to the receiving platform 611 in the second tank body 61, so that the receiving platform 611 can achieve the effect of flipping.

[0037] like Figure 2 As shown, in one embodiment, the receiving platform 611 includes a first half body and a second half body, the first half body and the second half body are spliced ​​into a disc structure, the first half body is fixedly connected to the second tank body 61, and the second half body is fixedly connected to the rotating rod 610 and rotates relative to the first half body under the driving action of the rotating rod 610.

[0038] In one embodiment, the rotating rod 610 is disposed at the bottom of the second half body so that when the rotating rod 610 drives the second half body to rotate relative to the first half body, the edge of the first half body will not block the second half body and prevent the second half body from rotating.

[0039] In one embodiment, the first and second halves are connected by a hinge. In the above technical solution, when the receiving platform 611 is in its initial state, the first and second halves are located on the same horizontal plane, forming a disc-shaped structure to receive material added to the second tank 61. After the material is cleaned, the first motor 66 drives the rotating rod 610 to cause the first half to flip downward, allowing the material to fall downward and enter the next processing step.

[0040] In one embodiment, the receiving platform 611 is an integral body and is fixedly connected to the rotating rod 610. A lifting mechanism is provided on the top of the second tank body 61. The lifting mechanism is detachably connected to the second motor 612, so that the stirring mechanism including the second motor 612, the rotating rod 613, the stirring rod 614 and the stirring block 615 can be lifted and lowered in the vertical direction under the action of the lifting mechanism.

[0041] In the above technical solution, after the material is cleaned, the stirring mechanism stops stirring, and the lifting mechanism drives the stirring mechanism to rise in the vertical direction to avoid the receiving platform 611 from colliding with the stirring mechanism when it is flipped over. Then the first motor 66 drives the rotating rod 610 to drive the receiving platform 611 to flip over, pouring the material downward so that the material enters the next processing step. Then the first motor 66 drives the receiving platform 611 to flip over again to ensure that the groove surface of the receiving platform 611 can face upward without affecting the stirring and washing effect. Finally, the lifting mechanism lowers the stirring mechanism to restore it to its initial state and the next washing step can be carried out.

[0042] like Figure 2 、 Figure 5 As shown, in one embodiment, the liquid inlet assembly includes an annular tube 62 and a nozzle 63 connected to the annular tube 62, and multiple nozzles 63 are arranged on the inner side of the annular tube 62 at intervals along the circumferential direction. The annular tube 62 is sleeved on the outer periphery of the second tank body 61, and the nozzles 63 are passed through the second tank body 61 and connected to the inner cavity of the second tank body 61.

[0043] In the above technical solution, the annular tube 62 mainly serves to transport the cleaning liquid, and multiple nozzles 63 are arranged at intervals along the circumference on the inner side of the annular tube 62 and penetrate the second tank body 61, which can achieve the effect of spraying the cleaning liquid into the second tank body 61 simultaneously in multiple directions along the circumference.

[0044] In one embodiment, the liquid inlet assembly only includes an annular tube 62, which is sleeved on the outer periphery of the second tank body 61. A plurality of small holes for releasing cleaning liquid are arranged at intervals on the surface of the annular tube 62. Holes are also arranged at corresponding positions on the surface of the small holes of the annular tube 62 on the second tank body 61. Therefore, there is no need to set up a nozzle 63, and the cleaning liquid can be directly sprayed into the second tank body 61 through the annular tube 62.

[0045] In one embodiment, the liquid inlet component only includes a nozzle 63, which is installed on the second tank body 61. Specifically, it can be installed on the top of the second tank body 61, or on any position on the side wall higher than the receiving platform 611 to spray cleaning liquid into the second tank body 61.

[0046] like Figure 1 As shown, in one embodiment, a connecting pipe 5 is provided on the top of the first tank body 2 , and the second tank body 61 is detachably connected to the connecting pipe 5 .

[0047] In one embodiment, the connecting pipe 5 is fixedly connected to the first tank body 2 by welding.

[0048] In one embodiment, flanges are welded to the ends of the second tank body 61 and the connecting pipe 5 , and a plurality of bolts and nuts are used to achieve a detachable connection between the second tank body 61 and the connecting pipe 5 .

[0049] In the above technical solution, the material cleaned in the second tank body 61 falls into the first tank body 2 through the connecting pipe 5; the second tank body 61 and the connecting pipe 5 are detachably connected to facilitate the disassembly and assembly of the second tank body 61 and the first tank body 2 and subsequent cleaning and maintenance.

[0050] like Figure 4 As shown, in one embodiment, the separation mechanism 7 includes a third motor 71, a conveying shaft 72 and a filter screen 74. The third motor 71 is arranged at the end of the first tank body 2, the conveying shaft 72 is driven and connected to the third motor 71, the outer wall of the conveying shaft 72 is provided with a spiral push piece 73, the filter screen 74 is provided below the spiral push piece 73, the bottom of the second tank body 61 is provided with a liquid outlet 3, and the second tank body 61 is provided with a solid outlet 4 at the pushing end of the spiral push piece 73.

[0051] In one embodiment, the third motor 71 is detachably connected to the end of the first tank 2 .

[0052] In one embodiment, the spiral push piece 73 is fixedly connected to the outer wall of the conveying shaft 72 .

[0053] In one embodiment, the liquid outlet 3 is disposed at the bottom of the second tank body 61 away from the third motor 71 .

[0054] After the material that has been cleaned in the second tank body 61 falls into the first tank body 2, it accumulates between the blades of the spiral push piece 73. The third motor 71 drives the spiral push piece 73 to rotate, and pushes the material forward through spiral feeding. During the advancement of the material, the cleaning liquid is filtered out through the filter screen 74 and discharged from the second tank body 61 through the liquid outlet 3 at the bottom of the second tank body 61 away from the third motor 71. By setting the liquid outlet 3 at a position away from the material falling into the first tank body 2, the filtering distance of the filter screen 74 for the material is extended as much as possible, thereby improving the filtering effect, and the material is pushed out from the solid outlet 4 set at the pushing end by the spiral push piece 73, thereby preventing the solid material from accumulating on the filter screen 74 and clogging the filter holes, thereby achieving the effect of solid-liquid separation.

[0055] like Figure 4 As shown, in one embodiment, the filter screen 74 is arranged at the bottom of the inner cavity of the first tank body 2, and the inner cavity of the first tank body 2 is divided into two upper and lower cavities, so as to avoid the liquid from re-soaking the filtered material during the solid-liquid separation process, thereby reducing the effect of solid-liquid separation.

[0056] In one embodiment, the filter screen 74 is movably connected to the first tank body 2 .

[0057] The working process of the washing device for lithium carbonate production of the present invention is as follows: the crude lithium carbonate material to be cleaned is added into the second tank body 61 through the feed pipe 64, and the material to be cleaned falls on the receiving platform 611 which is spliced ​​into a disc shape by the first half body and the second half body, and then the cleaning liquid is sprayed into the second tank body 61 through the nozzle 63 by the annular pipe 62, and at the same time, the second motor 612 is started to drive the rotating rod 613 to rotate, driving the stirring rod 614, the stirring block 615 and the convex strip 616 arranged at the bottom of the stirring block 615 connected to the rotating rod 613 to rotate together, and the crude lithium carbonate material soaked by the cleaning liquid in the second tank body 61 is fully stirred and cleaned, and the bottom surface shape of the convex strip 616 at the bottom of the stirring block 615 facing the receiving platform 611 is adapted to the concave shape of the groove of the receiving platform 611, so that the material deposited and adhered to the surface of the receiving platform 611 can also be stirred After the crude lithium carbonate material is fully stirred and cleaned, the washing process is completed. The first motor 66 drives the rotating rod 610 to drive the first half of the receiving platform 611 to flip downward, so that the material on the first half falls. At the same time, the stirring mechanism still keeps rotating and stirring, and sweeps the material on the second half into the outlet formed by the downward flipping of the first half. The fallen material enters the first tank body 2 through the connecting pipe 5 and accumulates between the blades of the spiral push piece 73. The third motor 71 is started to drive the spiral push piece 73 to rotate, and the material is pushed forward by the spiral feed. During the advancement of the material, the cleaning liquid is filtered out through the filter screen 74 and discharged from the second tank body 61 through the liquid outlet 3 at the bottom of the second tank body 61, and the material is pushed out from the solid outlet 4 set at the pushing end by the spiral push piece 73, thereby preventing the solid material from accumulating on the filter screen 74 and clogging the filter holes, thereby achieving the effect of solid-liquid separation.

[0058] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: by setting a bracket 1 to support the washing device for lithium carbonate production, the posture of the washing device is restricted to prevent the washing device from rolling; the first tank body 2 is used to accommodate the separation mechanism 7 and the material after cleaning by the cleaning mechanism 6, providing a working space for the separation mechanism 7 to achieve solid-liquid separation of the cleaned material; the setting of the separation mechanism 7 can separate the material and the cleaning liquid after the solid-liquid mixture is cleaned by the cleaning mechanism 6; the cleaning mechanism 6 can fully stir and clean the material, and at the same time prevent the material from adhering to the inner surface of the device and the bottom of the second tank body 61, thereby further improving the washing effect; the second tank body 61 accommodates the stirring mechanism, the receiving platform 611 and the material, and is connected to the first tank body 2, the feed pipe 64 and the liquid inlet component on the outside, providing a working space for the stirring and cleaning related structures to fully stir and clean the material space; the feed pipe 64 connects the outside with the second tank body 61, and is used to add the material to be cleaned to the washing device; the liquid inlet component is mainly used to add cleaning liquid into the second tank body 61, and cooperates with the stirring mechanism to achieve the effect of cleaning the material; the stirring mechanism rotates in the second tank body 61, stirring the material and the cleaning liquid to fully contact and mix to achieve cleaning of the material; the receiving platform 611 is used to receive the material added to the second tank body 61, to avoid the material from accumulating at the bottom of the second tank body 61 and not being able to be fully stirred by the stirring mechanism, and at the same time, by setting the bottom surface of the stirring mechanism to a shape that is compatible with the receiving surface of the receiving platform 611, it is avoided that the material adheres to the surface of the receiving platform 611 and cannot be fully stirred by the stirring mechanism; after the material received by the receiving platform 611 is fully cleaned, the currently cleaned material is released by flipping the receiving platform 611 to enter the next processing step, and then the receiving platform 611 returns to its initial state and continues to receive the next batch of newly added materials. The above-mentioned embodiments of the present invention overcome the problem in the prior art that materials are easily sunk to the bottom and cannot be stirred, resulting in poor washing effect, by cooperating the stirring structure and the receiving platform in the cleaning structure; and overcome the problem in the prior art that materials are easily retained and accumulated on the filter screen, thereby affecting the filtering effect, by cooperating the spiral pusher and the filter screen in the separation mechanism.
