Description

Technical Field

[0001] This utility model belongs to the field of flotation machine technology, specifically relating to an automated flotation machine for mining. Background Technology

[0002] The flotation machine is driven by a motor and V-belt to rotate the impeller, which generates centrifugal force and creates negative pressure. On the one hand, it draws in sufficient air to mix with the slurry, and on the other hand, it stirs the slurry and mixes with reagents. At the same time, it refines the foam, so that the minerals adhere to the foam and float to the surface of the slurry to form mineralized foam.

[0003] Existing automated flotation machines for mining use involve mixing the slurry with air, but the mixing is insufficient and takes a long time to complete the flotation process, resulting in low efficiency. Therefore, it is necessary to design an automated flotation machine for mining to solve the above problems. Utility Model Content

The lower end of the rotating shaft 6 and the stirring fan 10 are connected by the transmission helical gear 9. An air outlet 12 is opened on the lower surface of the installation sleeve 7. The rotating shaft 6 drives the stirring rod 11 to rotate and stir, and simultaneously drives the stirring fan 10 to rotate and stir through the transmission helical gear 9. Air is introduced into the installation sleeve 7 through the air inlet pipe 5. The air is sprayed through the air outlet 12 to the position of the stirring fan 10, thereby quickly mixing with the slurry to generate flotation bubbles; the lower end of the mounting sleeve 7 is square in shape, the air outlet 12 is located at the four corners of the mounting sleeve 7, the lower end of the rotating shaft 6 passes through the mounting sleeve 7, and the stirring rod 11 is fixedly installed on the outer side of the lower end of the rotating shaft 6 and located on the lower side of the stirring fan 10, which facilitates rapid air circulation during use, and the air mixes with the rotation of the stirring fan 10 and the stirring rod 11, so that the slurry and air combine; the upper end of the flotation tank 1 is fixedly installed with the main frame 4, and the inner side of one end of the main frame 4 is fixedly installed with the motor 8. The output shaft of the motor 8 is connected to the upper end of the rotating shaft 6 through a belt and a pulley.

The motor 8 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the stirring rod 11 to rotate and stir. At the same time, the transmission helical gear 9 drives the stirring fan 10 to rotate and stir. The air inlet pipe 5 introduces air into the mounting sleeve 7, and the air is sprayed out through the air outlet 12 to the position of the stirring fan 10, thereby quickly mixing with the slurry to generate flotation bubbles. At the same time, the flotation bubbles float to the top and flow through the inclined surface into the overflow tank 2 and are discharged and collected through the discharge port 3.
