Abstract
An air agitation flotation machine comprises a tank body, a circulation drum and an air lifter are arranged in the tank body, a mixing box of the air lifter is placed at the lower part of the tank body, the inlet of the lifting pipe is connected to the mixing box, and the outlet faces the top of the circulation drum. The bottom of the circulation drum is provided with an adjustment slot for the passage of ore pulp, and a part of the ore pulp out of the adjustment slot is circulated to the suction port at the bottom of the mixing box of the air lifter, so as to realize axial circulation flow. The present invention utilizes the compressed air that needs to be added in the flotation process as the power to lift the ore pulp so that it forms a circulation flow in the tank, and the flow rate of the circulation flow can be adjusted by adjusting the air flow rate. The design of the ore feeding port, the diameter and the height of the circulation drum of the air lifter makes the fluid in the tank present a special axial flow, thereby realizing the suspension state of solid particles inside the tank body, eliminating the mechanical stirring device, saving energy consumption, simplifying the equipment manufacturing, reducing the operating cost, and avoiding the phenomenon of flower turning and sinking, and optimizing the operation index.
