Description

Low-grade salt lake lithium carbonate draws sedimentation tank

Technical Field

The utility model relates to a lithium carbonate draws the field, concretely relates to low-grade salt lake lithium carbonate draws sedimentation tank.

Background

Lithium has important significance in the field of energy and new materials, and the source of the lithium is lithium ore and salt lake brine. In the past, the raw materials for producing the lithium salt are mainly lithium ores, but the cost for producing the lithium salt from the lithium ores is high, the environmental burden is heavy, and the lithium salt is produced by utilizing salt lake brine more in the future. However, most of the existing salt lakes are low-grade salt lakes which cannot be fully used, the development difficulty is high, the low-grade salt lakes generally undergo several steps of mixing, settling extraction, drying and the like in the process of extracting lithium carbonate, and therefore lithium carbonate finished products are obtained.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of the above existence, the utility model provides a low-grade salt lake lithium carbonate draws sedimentation tank.

The utility model discloses a realize through following technical scheme:

the utility model provides a low-grade salt lake lithium carbonate draws sedimentation tank, includes a plurality of collecting vat that sedimentation tank and lower part set up, be fixed with a plurality of baffle in the sedimentation tank, a plurality of baffle divide into multistage settlement processing region in with the sedimentation tank, and every baffle setting is used for separating between two collecting vats, the sedimentation tank of the upper portion central authorities of collecting vat is fixed with the baffle, and the slope is provided with two-layer and hinders the barrier net between every settlement processing region's baffle and the baffle.

Preferably, one side of the upper part of the sedimentation tank is communicated with an inlet pipe, and the other side of the upper part of the sedimentation tank is provided with a communicated outer discharge pipe.

Preferably, the bottom of collecting vat is fixed with the conveyer pipe intercommunication of carrying the lithium carbonate through a plurality of connecting pipe, the control valve is installed to the front end of conveyer pipe.

Preferably, a supporting column for supporting is arranged on the outer side of the sedimentation tank.

Preferably, the baffle and the partition in each sedimentation treatment area are arranged in a high-low step.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up multistage settlement processing region in the sedimentation tank to set up two-layer blocking net and can further hold back lithium carbonate precipitate material between baffle, the baffle in every settlement processing region, finally handle the lithium carbonate content greatly reduced in the outer discharge of pipe bittern from arranging through multistage sedimentation, the at utmost has prevented the waste of lithium carbonate.

Drawings

Fig. 1 is a perspective view of the structure of the present invention;

FIG. 2 is a partially cut-away schematic view of FIG. 1;

FIG. 3 is a front view of FIG. 1;

in the figure: the device comprises a sedimentation tank 1, a collecting tank 2, a partition plate 3, a baffle plate 4, a blocking net 5, a conveying pipe 6, a connecting pipe 7, a control valve 8, an inlet pipe 9, an outer discharge pipe 10 and a support column 11.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, fig. 2 and fig. 3, a sedimentation basin is extracted to low-grade salt lake lithium carbonate, including sedimentation basin 1 and a plurality of collecting vat 2 that its lower part set up, sedimentation basin 1 internal fixation has a plurality of baffle 3, and a plurality of baffle 3 divides into multistage sedimentation processing region in with sedimentation basin 1, and every baffle 3 sets up and is used for separating between two collecting vats 2, sedimentation basin 1 at the upper portion central authorities of collecting vat 2 is fixed with baffle 4, and the slope is provided with two-layer barrier net 5 between baffle 3 and the baffle 4 in every sedimentation processing region.

An inlet pipe 9 is communicated with one side of the upper part of the sedimentation tank 1, and an outer discharge pipe 10 is communicated with the other side of the upper part of the sedimentation tank 1.

The bottom of collecting vat 2 is fixed with the conveyer pipe 6 intercommunication of carrying the lithium carbonate through a plurality of connecting pipe 7, control valve 8 is installed to the front end of conveyer pipe 6.

And a supporting column 11 for supporting is arranged on the outer side of the sedimentation tank 1.

The baffle 4 and the partition 3 in each sedimentation treatment area are arranged in a high-low step.

The working principle is as follows: when the utility model is used, brine enters the sedimentation tank 1 of the sedimentation treatment area of the first level from the inlet pipe 9, flows along the lower part of the opposite baffle 4, enters the collecting tank 2 of the first level, flows into the sedimentation treatment area of the next level through the baffle 3 to be precipitated in sequence, therefore, the lithium carbonate is precipitated at the bottom of the collecting tank 2 in the multistage sedimentation treatment area, lithium carbonate is gathered in the collecting tank 2, lithium carbonate precipitate is further intercepted every time the lithium carbonate passes through the two layers of arresting nets 5 between the partition plates 3 and the baffle plates 4, the lithium carbonate content in brine discharged from the outer discharge pipe 10 after the multistage sedimentation treatment is finally greatly reduced, the waste of the lithium carbonate is prevented to the maximum extent, when more lithium carbonate is gathered in the collecting tank 2 at the lower part of the plurality of sedimentation tanks 1, the control valve 8 may be opened and the accumulated lithium carbonate discharged through the connecting pipe 7 into the delivery pipe 6.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
