[0072] Embodiment two:

[0073] The embodiment provides a method for efficiently preparing lithium carbonate based on spodumene based on the embodiment one, and steps are as follows:

[0074] Firstly, the spodumene is crushed to make the particle size of the spodumene uniform.

[0075] More specifically, the particle size of the spodumene in the embodiment is between 0.5 mm and 5 mm, in this particle size range, the spodumene has a large specific surface area, which is beneficial to leaching of lithium, and has a certain firmness, and can withstand a certain grinding and crushing pressure.

[0076] Secondly, the crushed spodumene is reacted with a chemical solvent to leach lithium ions.

[0077] It can be understood that in the embodiment, the chemical solvent is a sodium hydroxide solution, the sodium hydroxide solution is an alkaline substance, and can react with the spodumene to release lithium ions,

[0078] Thirdly, the leached solution is centrifugally separated and filtered to perform solid-liquid separation.

[0079] Fourthly, the solution after the solid-liquid separation is concentrated.

[0080] Further, in the embodiment, the solution concentration method is evaporation, the solution is gradually volatilized by heating, part of the solvent molecules in the solution escape, and the concentration of the remaining lithium ions is increased.

[0081] Fifthly, the concentrated solution is reacted with a reagent to precipitate cations in the solution.

[0082] More specifically, the reagent in the embodiment is hydrochloric acid.

[0083] Sixthly, the precipitated solution is subjected to solid-liquid separation to obtain a pure lithium carbonate solution.

[0084] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0085] In operation, firstly, the transmission motor 10 is started to drive the crushing roller 8 connected thereto to rotate, and under the connection of the two linkage spur gears 9, the two crushing rollers 8 are simultaneously rotated, then the spodumene raw material is put into the crushing box 7 to crush the spodumene raw material by the crushing roller 8, the crushed raw material is screened by the dropping hole 13, so that the raw material meeting the subsequent leaching operation falls through the dropping hole 13 and is collected, then is transmitted into the inside of the feeding cylinder 43, and the raw material not meeting the leaching operation is directly discharged;

[0086] The raw material entering the feeding cylinder 43 can be driven to rotate by the feeding motor 46 driving the feeding shaft 44, and the spiral conveying piece 45 is connected with the feeding shaft 44, so that the spiral conveying piece 45 conveys the raw material upward to the inside of the reaction box 14, then the sodium hydroxide solution is added to the inside of the reaction box 14, then the driving motor 19 is started to drive the transmission shaft 15 to rotate, so that the raw material and the sodium hydroxide solution are stirred by the stirring blade 17, since the sodium hydroxide solution is an alkaline substance, it can react with the spodumene raw material to release lithium ions, and when the stirring blade 17 stirs, the temperature generated by the temperature control electric heating wire 18 is directly transmitted to the raw material in the reaction box 14 through the stirring blade 17, so that the raw material reaches a suitable reaction temperature;

[0087] In combination with the setting of the linkage belt 33, the linkage shaft 22 can be driven to rotate during the rotation of the transmission shaft 15, and in combination with the connection of the eccentric transmission plate 23 and the guide frame 25, the eccentric transmission plate 23 can drive the guide frame 25 to reciprocatingly displace under the limitation of the limiting frame 24, so as to drive the transmission rack 26 to drive the linkage shaft 27 to rotate, and the power of the linkage shaft 27 is transmitted through the driving bevel gear 29, so that the raw material in the reaction box 14 is stirred by the turbulence shaft 21, and since the transmission rack 26 reciprocatingly slides, when the transmission rack 26 upwardly displaces, the linkage shaft 27 rotates clockwise, when the transmission rack 26 downwardly displaces, the linkage shaft 27 rotates counterclockwise, so as to reverse the turbulence shaft 21, thereby ensuring the stirring effect of the turbulence shaft 21;

[0088] After the leaching reaction, the solution in the reaction box 14 is pumped out through the outer guide pipe 40 by the liquid pump 39, and is transmitted into the inside of the centrifuge 6 through the transmission pipe 41, then the solid and the fluid in the solution are separated by the operation of the centrifuge 6, then the guide plate 37 is pulled by the hydraulic rod 38, since the guide plate 37 is supported by the blocking shaft 35, the blocking shaft 35 is driven to rotate, so that a gap exists between the blocking plate 36 and the discharge pipe 34, and then the raw material in the reaction box 14 can be discharged through the gap;

[0089] The solution separated by the centrifuge 6 is taken out and poured into the concentration tank 49, and the concentration electric heating wire 51 is started to work, the temperature of the concentration electric heating wire 51 is directly transmitted to the solution through the temperature guide cover 50, a part of the solvent molecules in the solution evaporate and escape, and the remaining lithium ions are concentrated;

[0090] The electromagnetic valve at the joint of the concentration tank 49 and the precipitation tank 48 is opened, the solution in the concentration tank 49 is poured into the precipitation tank 48, and hydrochloric acid and other reagents are added into the precipitation tank 48, the other cations in the solution are precipitated by the reaction between the reagents and the solution, the transmission pump 52 is started to work to pump the solution in the precipitation tank 48 out through the outlet pipe 53 and send it to the centrifuge 6 through the transmission pipe 54, and finally the solid and the fluid in the solution are separated by the centrifuge 6, and the relatively pure lithium carbonate solution is obtained.
