A device for weakening the oscillation energy of foam and pulp interface

Abstract

The invention discloses a device for reducing oscillation energy on a foam and ore pulp interface. A plurality of a plurality of oscillation dampers, an annular air distribution pipe, a radial air distribution pipe and a main air distribution pipe are arranged on the foam and ore pulp interface. The oscillation dampers naturally float on the interface in ore pulp. The oscillation dampers are evenly distributed in the circumferential direction and are connected with the annular air distribution pipe. The annular air distribution pipe communicates with the main air distribution pipe through theradial air distribution pipe. Each oscillation damper comprises a lower tank body and a sealing cover, wherein an air inlet pipe is arranged on the sealing cover and communicates with the annular airdistribution pipe, oscillation whiskers are arranged on the side wall of an upper opening of the lower tank body, and the lower tank body is filled with matching sand. According to the device for reducing oscillation energy on the foam and ore pulp interface, the oscillation effect generated when bubbles penetrate through the interface is avoided through energy absorption or transferring, particlefalling caused when the bubbles penetrate through the interface is reduced, and thus, the flotation and recovery efficiency is improved.

Description

technical field [0001] The invention relates to a flotation machine, in particular to a device for weakening the oscillation energy of the foam and pulp interface. Background technique [0002] 90% of non-ferrous metals and 50% of ferrous metals in the world are processed by flotation. The flotation machine is one of the most important supports to realize the flotation process. The flotation machine is a kind of equipment that uses the difference of hydrophobicity and hydrophilicity of minerals under the condition of gas-liquid-solid three-phase to realize the collision, adhesion, transportation and final recovery of the target minerals by air bubbles. There are complex dynamic processes in the flotation process, and the flotation machine can generally be divided into four areas: stirring and mixing area, transport area, separation area and foam area, such as figure 1 shown. [0003] The stirring and mixing zone is a very important area in the flotation machine. Most of t...

Problems solved by technology

[0007] The above-mentioned existing technical methods mainly focus on the rapid outflow control of the foam, and ignore the interphase interaction of the interface, and do not involve the control of the interface energy release process between the pulp phase and the foam phase.
