Abstract
The invention belongs to the technical field of mineral separation and particularly relates to a novel injection suction stirring flotation machine. According to the novel injection suction stirring flotation machine, a deflector is adopted to replace a stirring impeller of a mechanical stirring type flotation machine, so that the friction energy loss between the impeller and a shaft as well as the inner energy loss caused by ore pulp stirring through the impeller are reduced, and the flotation energy loss is reduced; the static deflector conducts stream guidance on submerged jet fed materials for three times, and ore pulp, medicaments and bubbles are fully mixed in wider sections in a groove with rolling and stirring of the ore pulp in the groove; meanwhile, the static deflector can control an ore pulp mixing circulating area through induction in the ore pulp flow direction, thus, the situation that a mineralized bubble transportation area and a foam layer are disturbed by the ore pulp mixing circulating area is avoided, and a good flotation environment is formed; and in addition, the larger bubbles in the ore pulp are subjected to repeated cutting and impact crushing through the deflector, bubbles with smaller particle sizes are formed and fully and uniformly distributed in all sections in the groove along the deflector, and full mineralization is achieved.
