But, utilize tradition solar pond from carbonate type bittern during crystallization lithium carbonate, exist with Lower deficiency: firstly, since low temperature richness lithium carbonate brine relies in lower troposphere 3 in tradition solar pond The effect of troposphere 1 and non-convection layer 2 carries out accumulation of heat, insulation, and the speed of separating out of such lithium carbonate is relatively slow, Productivity is low.Secondly, tradition solar pond is not closed structure, when ambient temperature is relatively low, and higher troposphere 1 Can freeze, thus affect solar energy and transmit downwards, thus affect salinity gradient and the insulation effect of non-convection layer 2 Really, so descend troposphere 3 just can not maintain higher temperature, thus affect the crystallization of lithium carbonate.Again Secondary, tradition solar pond is affected bigger by outside air temperature, it is impossible to whole year operation, limits the yield of lithium carbonate. Thirdly, higher troposphere 1 is highly prone to strong wind, sand and dust affect and are destroyed, and loses insulation more or less And with the salinity gradient effect of non-convection layer 2.

Therefore, improve the structure of solar pond, improve the solar pond crystallization rate to lithium carbonate, extend solar pond Year run the time, thus the crystallizing cycle shortening lithium carbonate is lithium carbonate salt lake carries lithium process-technology-evolutions One of direction.

As it is shown in figure 1, Wen Peng pond 1 includes cell body 10 for accommodating salt and for thermal-arrest, insulation Diffuser 20, diffuser 20 seals the opening of cell body 10, thus, Wen Peng pond 1 forms a knot sealed Structure.Cell body 10 has specific width and depth characteristic, i.e. along the length direction of cell body 10, cell body 10 Width be gradually reduced, and the degree of depth of this cell body 10 is gradually increased.In the present embodiment, cell body 10 substantially in Trapezoidal, as shown in Figure 2.

In conjunction with Fig. 1 and Fig. 2, cell body 10 includes first pool wall the 11, second pool wall 12, connects the first pool wall 11 and second pool wall 12 two the 3rd pool walls 13, gradient ponds at the bottom of.Multiple and horizontal plane is included at the bottom of gradient pond At the bottom of parallel horizontal pond 14 and multiple 14 inclined-planes 15 tilted at the bottom of with horizontal pond.First pool wall the 11, second pond Wall the 12, the 3rd pool wall 13 encloses one continuous print tubular pool wall of formation, certainly, the first pool wall 11, second Pool wall the 12, the 3rd pool wall 13 can be structure as a whole.Diffuser 20 seals the opening of cell body 10, thus, Wen Peng pond 1 forms a structure sealed.

Fig. 2 is the cross sectional representation in Wen Peng pond 1, it is clear that the width of the first pool wall 11 is more than the second pool wall The width of 12.The degree of depth of the second pool wall 12 is more than the degree of depth of the first pool wall 11, i.e. the degree of depth of cell body 10 Gradually deepen along himself length direction (i.e. direction from left to right in Fig. 1).Along cell body 10 Length direction, at the bottom of gradient pond in multiple horizontal pond at the bottom of 14 width taper into, i.e. multiple horizontal ponds The area at the end 14 is gradually reduced.It is to say, along the length direction of cell body 10, cell body 10 has multiple The shallow pond of large area (i.e. being formed by the bottom of the horizontal pond of multiple large area 14) and multiple deep pond of little area are (i.e. by multiple At the bottom of little area levels pond, 14 are formed), these shallow ponds and Shen Chi together form at the bottom of the gradient pond of cell body 10. The shallow pond of the plurality of large area is heat exchange pond, and the effect in the shallow pond of multiple large area is so that from outside low temperature Salt is rapidly heated；The plurality of deep pond of little area is thermal insulation pool, and the effect in multiple deep ponds of little area is to maintain Brine temperature, the precipitation of prolongation lithium carbonate and recrystallization are to obtain high-quality crystallization of lithium carbonate body 30.This reality Executing in example, first shallow pond of large area (near the shallow pond of the first pool wall 11) is heat exchange pond, be used for so that It is rapidly heated from outside low temperature salt；And follow-up each deep pond (being formed by the bottom of multiple horizontal ponds 14) is Thermal insulation pool, is only to maintain brine temperature and extends the precipitation of lithium carbonate and recrystallization to obtain high-quality lithium carbonate Crystalline solid 30.

During utilizing Wen Peng pond 1 to separate out lithium carbonate, theoretically, Wen Peng pond can reach to rise for 1 one days Temperature separates out the primary condition of lithium carbonate: as long as the salt thickness in Wen Peng pond 1 is less than 10cm, every day is single Plane amasss the solar energy of acquisition can make brine temperature deep for 10cm raise more than 20 DEG C.Salt is at Wen Peng In pond 1, the thickness of the time of staying and salt is inversely proportional to, and the volume of salt is the product of the degree of depth and surface area, this Sample can calculate the width of the first pool wall, the degree of depth and length by year brine treatment amount, it is also possible to constructs Two pool walls and other pool wall.According to said method, (that is, the required year brine treatment amount being actually needed can be built ) Wen Peng pond 1.
