The flotation machine comprises a flotation tank, a concentrate overflow tank, aflotation tailing tank an ore pulp level adjusting mechanism, a transmission device support and a high-strength mechanical stirring mineralization chamber arranged in the middle of the flotation tank. According to the flotation machine, the structure is simple, the design is reasonable, and the effects of being capable of achieving the particle bubble collision mineralization and achieving the relatively independent separation step of the article bubble aggregate from the ore pulp are achieved; and the energy consumption of mechanical stirring is mainly applied to the particle bubble collision mineralization, so that the fine particle mineralization efficiency and the flotation rate are improved, then the recovery rate and the selectivity of the fine particle flotation are synchronously improved, the energy consumption of the flotation process is reduced, and the effect of being efficient and energy-saving are achieved.

Description

technical field [0001] The invention belongs to the field of coal and mineral flotation, and in particular relates to a high-intensity stirring mineralization flotation machine with relatively independent steps for the forced collision mineralization of particle bubbles and the separation of particle bubble aggregates from ore pulp. Background technique [0002] Flotation is a technology widely used in the high-efficiency separation of fine-grained coal and minerals. It is usually achieved through flotation equipment. At present, there are two main types of flotation equipment: mechanical agitation flotation machines and flotation columns . The mechanical agitation flotation machine is mainly composed of a sorting tank, a concentrate and tailings discharge mechanism, an inflatable agitation mechanism and a liquid level adjustment mechanism. The aeration agitation mechanism is the core of the flotation machine. The conventional mechanical agitation flotation Usually, it is a...

Problems solved by technology

[0003] The surface properties and buoyancy of minerals have the characteristics of wide distribution and nonlinearity. In theory, different agitation and aeration mechanisms are required to create different hydrodynamic conditions to meet the different flow fields required for the collision mineralization of different buoyant mineral particles and air bubbles. environment, the aforementioned multi-cell flotation machines usually use the same aeration and agitation mechanism, and the agitation and aeration flow field environment generated by the same agitation and aeration mechanism is the same. In each flotation cell, mineral particles are used under the same agitation and aeration conditions to achieve Collision mineralization with air bubbles obviously does not meet the different requirements of the non-linear characteristics of mineral buoyancy and wide distribution for mineralization flow field conditions. Therefore, in actual production, it shows the technical problem of poor flotation effect on complex and difficult-to-separate minerals. Under the circumstances, it is necessary to form a complex process flow with multiple slots and sections to achieve efficient separation. The process flow is lengthy and complicated, and the production and management costs are high, which directly affects the improvement of the technical and economic benefits of the dressing plant.
