Microbubble static modularized flotation device

Abstract

The invention discloses a microbubble static modularized flotation device. The device comprises a plurality of tanks integrally communicated with each other; a plurality of flotation units are evenly and symmetrically in any one tank; a feeding pipe for feeding materials to the flotation units in the first tank at the side edge of the first tank, and correspondingly, a tailing opening for discharging tailings is formed at the side edge of the last tank; concentrate collecting grooves are further distributed between the floatation units and on the two sides in the direction of the feeding pipe in any tank; a swirl injection device is mounted at the bottom of any flotation unit, and a fairing for dispersing the flow direction of gas-bearing ore pulp is arranged on the upper part of the injection orifice of the swirl injection device in any flotation unit; a spraying device for promoting concentrate foam to move towards the concentrate collecting groove is arranged next to the concentrate collecting groove on the upper part of any flotation unit. A rectifying plate for stabilizing the flow state of the flow field is further mounted on the middle upper part of any tank. The microbubble static modularized flotation device is simple in structure, efficient and energy-saving, high in treatment capacity; as a result, the flotation efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical equipment field of mineral separation, in particular to a microbubble static modular flotation device. Background technique [0002] Flotation is the most important interface sorting method. It is generally used for the separation of -0.5mm coal slime, and it is the only effective separation method for -0.1mm coal slime. There are many types of flotation machines, and the differences are mainly reflected in the aeration method and the structure of the aeration stirring device. Therefore, the most widely used classification method is to divide the flotation machines into two categories according to the different aeration and agitation methods, that is, the mechanical agitation type. and without mechanical stirring. The mechanical agitation flotation machine uses the agitator to stir to complete the suction and division of the air bubbles. It has a history of nearly a hundred years from ore dressing to coal prepar...
