The invention discloses a flotation machine impeller for increasing the width of a conveying area. The flotation machine impeller comprises a circular cover plate. The upper portion of the circular cover plate is provided with an upper blade and an upper air dispersing device. The lower portion of the circular cover plate is provided with a lower blade and a lower air dispersing device. An inner air channel hole is formed in the middle of the circular cover plate. An inner channel of the lower air dispersing device is communicated with an inner channel of the upper air dispersing device through the inner air channel hole. By means of the upper blade, ore pulp above the impeller is stirred and guided air is dispersed with force, and therefore the circulation of the ore pulp at the bottom ofa flotation machine and the dispersion of the guided air are fused by means of the upper blade and the lower blade, the upper limit width of the conveying area of the flotation machine is increased,the requirements for powerfully stirring the ore pulp and dispersing the air in a stirring and mixing area of the flotation machine are met, and the requirements for effective air dispersion and ore pulp circulation of the operation central area of the conveying area are met.
Description
technical field [0001] The invention relates to a flotation machine impeller, in particular to a flotation machine impeller with widened transport area. Background technique [0002] The flotation machine is a kind of equipment used for mineral separation under the condition of gas-liquid-solid three-phase. It is mainly composed of a driving device, a stirring shaft system, an impeller, a stator and a tank. The flotation machine mainly realizes the suspension of the pulp in the flotation tank and the mineralization of the collision of useful minerals and air bubbles through impeller agitation. The impeller of the flotation machine is responsible for the functions of energy input, bubble generation and dispersion, and slurry suspension, and is the most critical component of the flotation machine. With the continuous development of large-scale flotation equipment, the impeller needs to carry greater torque, and its structural design and performance design should have the char...
