For those skilled in the art, the specific meaning of the above terms in the present patent can be understood according to the specific circumstances.
[0026] Referring to Figures 1-5 , a high-efficiency sorting lithium pegmatite and lithium spodumene pressureless heavy medium separator, comprising: a first cyclone 1, a second cyclone 2, the first cyclone 1 usually adopts a cylindrical structure, is designed to be inclined, and has a cylindrical distribution with increasing density from the center to the cylinder wall. This structure is conducive to the stability of the suspension density, and can perform high-precision sorting according to the given suspension density. The second cyclone 2 usually adopts a cylindrical-conical structure, which is conducive to expanding the two-stage sorting density difference and realizing high-density sorting. At the same time, by changing the diameter of the second underflow port and adjusting the insertion depth of the second overflow pipe, online adjustment of the second sorting density can be realized. The first cyclone 1 and the second cyclone 2 are connected through a connecting pipe 1 4. The upper part of the first cyclone 1 is connected to the upper feeding hopper 7 through a connecting pipe 2 8. The mineral is fed from the upper feeding hopper 7 by gravity. This pressureless feeding method reduces energy consumption and avoids problems such as over-grinding and large blockage. The medium pipe 6 is connected to the first cyclone 1, the upper feeding hopper 7 and the connecting pipe 2 8. One end of the medium pipe 6 is used to connect the delivery pump. The heavy medium suspension enters the first cyclone 1 at a certain working pressure, so that the heavy medium suspension circulates in the separator.
[0027] During the sorting process, according to the density difference of the ore, the minerals are separated under the action of the heavy medium. The lithium spodumene particles with larger density will sink to the bottom, while the lithium pegmatite particles with smaller density will float on top.
[0028] And, the epi-didymus particles are discharged through the epi-didymus discharge port 3 at the bottom of the first cyclone 1, and the spodumene particles are discharged through the spodumene discharge port 5 at one end of the second cyclone 2.

[0030] Further, as shown in the figure, Figure 3 the first guide box 12 and the second guide box 13 are in communication with the inside of the bottom bin 9, and the inside of the bottom bin 9 is integrally provided with a partition plate to divide the internal space into two, forming two separate storage spaces for epi-didymus and spodumene.
[0031] Specifically, as shown in the figure, Figure 4 both ends of the bottom bin 9 are fixedly installed with a first electric cylinder 15, and the telescopic ends of the first electric cylinder 15 are connected with a first push plate 16, and the operation of the first electric cylinder 15 can drive the first push plate 16 to push to the middle, so as to push the internal minerals to avoid concentrated accumulation.
[0032] And, the medium recovery tank 10 is integrally connected below the bottom bin 9.

[0041] In this embodiment, during the collecting process, the corresponding second electric cylinders 18 are started to drive the second push plates 19 to move forward, so as to push the petalite or spodumene inside the bottom bin 9 out of the corresponding material collecting openings 21, and then fall into the corresponding material collecting boxes 22 for collection, without manual collection and treatment.
[0042] It should be noted that the bottom bin 9 can be designed of transparent material, so as to facilitate real-time observation of the amount of minerals inside.
[0043] Working principle: when the utility model is used, the first and second through boxes 12 and 13 are additionally arranged at the upper petalite discharge port 3 and the lower spodumene discharge port 5, and the minerals are guided into the bottom bin 9 through the two through boxes, so that the minerals are stored inside the bottom bin 9. The bottom of the bottom bin 9 is provided with a filter plate 14, the heavy medium suspension discharged with the minerals can be filtered through the filter plate 14, the filtered heavy medium suspension enters the medium recycling box 10, and can be treated for secondary use to reduce resource waste.
