[0015] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0016] The utility model provides a high-efficiency separation device for polymetallic ores, which is mainly used for flotation of pulp containing multiple metallic ores. The main body consists of three parts: a base 1, a mixing chamber 2, and a separation chamber 3. The height of the pulp liquid level inside the main body is close to the height of the outlet on one side of the separation chamber 3, and the pulp is added at any time with the change of the liquid level height. The pulp treated with medicine is transported by a conveyor to the connection port above the outer wall of a pressure increasing cover 8, and then is transported into the pressure increasing cover 8. The connection port below the outer wall of the pressure increasing cover 8 is connected to the outside of the device through a conduit. When a driving mechanism 5 drives a worm 9 to rotate through a transmission shaft 6, the pulp inside the mixing chamber 2 is continuously transported from above to below the pressure increasing cover 8. Since the inner diameter of the pressure increasing cover 8 gradually becomes smaller from top to bottom, the fluid velocity below is much greater than that above. According to Bernoulli's principle, outside air is transported into the pressure increasing cover 8 through the conduit along the lower connection port. Since an annular groove is provided at the connection between the inside of the pressure increasing cover 8 and the lower connection port, and multiple through holes pointing to the inside of the pressure increasing cover 8 are provided on the inner wall of the annular groove, the outside air is sprayed onto the pulp flowing at high speed in an annular shape, thereby generating bubbles, and separation is carried out through hydrophobicity and hydrophilicity. When the air intake is insufficient, air can also be filled through a device for transporting air such as an air pump connected to the conduit. After the pulp carrying bubbles is ejected from below the pressure increasing cover 8, the worm 9 drives a baffle 11 below it to rotate, causing the pulp liquid phase to diffuse around, and scouring the sedimentary minerals deposited below the mixing chamber 2. Since the inner walls around the mixing chamber 2 adopt an arc structure, the pulp flowing from the bottom to the periphery can flow to the edge and then flow upward, thereby realizing the microcirculation of the liquid inside the mixing chamber 2. Since the pulp flowing to the upper part of the mixing chamber 2 stalls severely, and the worm 9 is relatively small and the suction force on the upper pulp inside the mixing chamber 2 is also small, the hydrophobic pulp is separated from the generated foam. The foam continues to flow upward to the liquid surface under the action of buoyancy, and the driving mechanism drives a foam scraping frame 7 to rotate to push the foam towards the outlet of the separation chamber 3 for discharge.

[0017] Through the annular groove and the through holes, the bubbles are sprayed onto the flowing pulp in an annular shape, enabling the pulp to be in full contact with the bubbles. The flow rate of the pulp is increased through the pressure increasing cover 8, and the rotating baffle 11 causes the pulp flowing at high speed to scour the sediment below the mixing chamber 2, thereby realizing the microcirculation of the pulp in the entire mixing chamber, enabling the bubbles to be fully mixed with the pulp, and increasing the flotation efficiency.

[0018] The driving mechanism 5 is installed on a motor frame 4 and consists of two groups of motors and a transmission mechanism, respectively driving the transmission shaft 6 and the foam scraping frame 7 to rotate.

[0019] The base 11 is composed of legs and a hollow annular boss with external threads. The legs are installed below the interior of the mixing bin 2, and the space between the legs is used to accommodate the baffle 11. After an annular groove and an annular through-hole connected thereto are machined under the pressure increasing cover 8, the pressure increasing cover 8 is installed on the base 11 through internal threads, so that the opening for machining under the annular groove is closed, leaving only the through-hole pointing to the interior of the pressure increasing cover 8. At the same time, the annular groove is communicated with the lower connection port, ensuring that air enters from the connection port and fills the annular groove, and finally sprays out through the annularly arranged through-holes. The setting of the base 11 simplifies the machining difficulty of the annular groove.
