Abstract

The invention provides a flash flotation machine and a pulp discharge method thereof, which relate to the technical field of mining equipment. The flash flotation machine includes a tank body, a spray compensation component and a concentration adjustment component; the tank body is provided with a middle valve and a The bottom valve; the spray compensation component is set on the top of the tank body, which is used to compensate the spray water into the tank body to dilute the slurry concentration in the tank body; the concentration adjustment component includes a connected rotating pipe and a fixed pipe, and the rotating pipe is far away from the fixed pipe. One end is located in the middle area of ​​the tank body, the end of the fixed pipe away from the rotating pipe is connected to the middle valve, and the rotating pipe rotates relative to the fixed pipe to discharge the slurry at different heights in the tank body. The flash flotation machine solves the technical problem that the liquid level control valve in the prior art is difficult to adjust the concentration of the pulp in the flotation machine, resulting in that the concentration of the discharged pulp is difficult to change according to the process conditions.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a flash flotation machine and a pulp discharge method thereof. Background technique [0002] The flash flotation machine is suitable for the treatment of coarse-grained and high-concentration pulp, and is generally used in the grinding and grading circuit. Each flash flotation machine system is mainly composed of the following parts: motor, stirring mechanism, bracket, bottom valve and middle valve. [0003] The working process of the flash flotation machine is as follows: the pulp is fed tangentially from the middle of the flotation machine, the air from the blower enters the hollow shaft through the bearing seat of the stirring mechanism of the flotation machine and is distributed to the blades of the impeller, and the air is stirred by the impeller. It is sheared into small bubbles between the impeller and the stator. The bubbles collide with the mineral particles in...
