Description

Technical Field

[0001] The utility model relates to the technical field of flotation recovery, in particular to a lead-zinc-silver ore flotation recovery device. Background Art

[0002] The lead-zinc-silver ore flotation recovery device is a special equipment used to separate and recover useful minerals from lead-zinc-silver ores. It utilizes the differences in the physical and chemical properties of the mineral surface and adds flotation agents to make useful mineral particles adsorb on bubbles and float to the surface of the slurry, thereby achieving mineral separation and recovery.

[0003] Upon investigation, the Chinese utility model patent with publication number CN212681315U discloses a flotation machine for lead-zinc metal mines. The flotation machine optimizes the setting of the toggle mechanism. Under the action of the drive motor, the active bevel gear drives the bearing rod to rotate through the driven bevel gear. The rotation of the bearing rod causes the crank to rotate. A small cylinder is provided on the crank. The small cylinder cooperates with the U-shaped groove on the sheave to make the sheave rotate intermittently, so that the sheave intermittently drives the left blade and the right blade to rotate through the rotating shaft rod. Under the rotation of the left blade and the right blade, the bubbles carrying lead-zinc ore on the water surface are discharged and collected, thereby improving work efficiency; and the ore pulp after flotation needs to pass through a separation device to separate the floated target minerals from non-target minerals. However, since the ore pulp after flotation has a certain viscosity and contains a large number of bubbles inside, it is inconvenient to quickly screen and separate when passing through the separation device.

[0004] Therefore, the utility model provides a lead-zinc-silver ore flotation recovery device to solve the above problems. Utility Model Content

The stirring shaft drives the rotation of the rotating shaft through the transmission mechanism, and the puncturing roller and the cone thorns puncture the bubbles in the pulp during the rotation process, thereby increasing the efficiency of removing bubbles in the pulp.
