detailed description

Below in conjunction with accompanying drawing, the embodiment of the utility model is further elaborated.

As shown in Figure 1, a kind of low-grade salt lake lithium carbonate extracting settling tank provided by the present embodiment comprises a pond body 1, and a salt lake water inlet pipe 2 is arranged on the upper left side of the said pond body 1, and the salt lake water inlet pipe 2 passes through the salt lake water inlet pipe 2 to the pond body. 1 is discharged into the liquid to be settled, and the right side of the pool body 1 is provided with a water outlet 3, and the water outlet 3 is used to discharge the supernatant liquid in the pool body 1. The bottom of the pool body 1 is an inclined surface, and an inclined The surface setting can facilitate the collection of sediment. As a preference, the inclination angle α between the bottom of the pool body 1 and the horizontal plane is 40-50°. If the angle α is too large, the volume of the pool body 1 will be too small, which will reduce the The extraction rate increases the working time. If the angle α is too small, the sediment settled at the bottom of the tank body 1 is not easy to collect, so as a preference, the angle α is 40-50°, specifically 40°, 50° can be selected Or 45°, of course, other angle values within the numerical range can also be selected, which will not be described here one by one.

The pool body 1 is provided with a first baffle plate 4 and a second baffle plate 5, and the first baffle plate 4 and the second baffle plate 5 are arranged in parallel at intervals, thereby dividing the pool body 1 into three parts , the first baffle 4 is set close to the water inlet pipe 2 of the salt lake, and the first baffle 4 and the second baffle 5 are provided with flow ports 6 to allow the liquid in the pool body 1 to circulate. The level of the flow port 4 on the second baffle 5 is higher than the level of the flow port 6 on the first baffle 4, which will form a drop, so that the liquid will not be directly discharged from the liquid surface after entering the pool body 1 , that is, the residence time of the liquid in the pool body 1 is increased, the sedimentation effect is enhanced, and the production efficiency is ensured.
