Abstract

The invention discloses a flotation device for a mining flotation process, and belongs to the technical field of flotation processes. The flotation device for the mining flotation process comprises a flotation machine body, the flotation machine body comprises a flotation cylinder, a feeding cylinder is fixedly connected to the center of the interior of the flotation cylinder, the feeding cylinder comprises a cylinder body, a rotating shaft is rotationally arranged in the middle of the cylinder body, a fan-shaped outlet is formed in the bottom of the cylinder body, and the fan-shaped outlet is communicated with the flotation cylinder. A fan-shaped outlet is formed in the bottom of the barrel, a rotary gate is rotationally connected to the bottom of the barrel in an embedded mode, a notch corresponding to the fan-shaped outlet in shape is formed in the rotary gate, a sleeve is fixedly connected to the bottom of the rotary gate, an air inlet device is connected to the bottom of the timing control device, and an air pressure balancing device is arranged in the air inlet device. The flotation machine effectively solves the problems that when an existing flotation machine generates bubbles, one air inlet pipe is used for feeding air, the air pressure at the outlet position is different, the generated bubbles are different in size, and the flotation effect is poor.

Description

technical field [0001] The invention relates to the technical field of flotation technology, in particular to a flotation device for mine flotation technology. Background technique [0002] The flotation machine process, also known as flotation beneficiation, refers to the process of separating mineral particles by using the physical and chemical properties of the mineral surface, and is the most widely used beneficiation method. When the existing flotation machines generate air bubbles, an air intake pipe is used to inhale air. The air pressure at the outlet position is different, and the size of the air bubbles produced is also different, and the flotation effect is poor; The frequency is also different, and it is difficult for the existing equipment to change the feeding frequency according to the change of the flotation frequency. Contents of the invention [0003] 1. Technical problems to be solved [0004] The object of the present invention is to provide a kind of...
