Novel flotation machine

Abstract

The invention discloses a novel flotation machine, wherein firstly, an air guide fan blade is arranged on a main shaft, the air guide fan blade can actively drain air in an air guide pipe downwards while rotating and working through the main shaft, and then through double inflation of an air inlet pipe and the air guide fan blade, the inflation amount can be increased, and the probability that ore grains collide with bubbles and adhere to the air can be increased; in addition, through the arrangement of a driving device, two main shafts can be driven to rotate simultaneously, a single motor does not need to drive a single main shaft, and therefore energy consumption is reduced to the minimum. In addition, a plurality of flotation areas share one raw ore pulp tank for feeding, so that the purposes of saving energy and reducing consumption can be achieved; meanwhile, a rotary sealing part is arranged on a feeding pipe connected with the raw ore pulp tank, the feeding pipe is opened when the rotary sealing part rotates, meanwhile, ore pulp can be stirred, then chemicals are added from a chemical feeding pipe, and the chemicals are stirred with the ore pulp while being added, so that the ore pulp and the chemicals are fully mixed; and the mineral separation time and efficiency can be improved.

Description

technical field [0001] The invention relates to the field of flotation machines, in particular to a novel flotation machine. Background technique [0002] Flotation machine is an important equipment to realize mineral flotation enrichment and separation. The technical and economic indicators of flotation are closely related to the flotation equipment used. There are many types of known flotation equipment, which are mainly divided into mechanical agitation flotation machines, inflatable agitation flotation machines, and inflatable flotation machines. For mechanical agitation flotation machines, the introduction of air is realized by the negative pressure generated by the high-speed rotation of the agitation impeller. When the agitation intensity is low, the generated vacuum is low, the amount of air introduced is insufficient, the flotation recovery rate is not high, and the agitation intensity is low. When it is high, the mechanical wear is serious and the energy consumpt...

AI Technical Summary

Problems solved by technology

For the mechanical stirring flotation machine, the introduction of air is realized by the negative pressure generated by the high-speed rotation of the stirring impeller. When it is high, the mechanical wear is serious and the energy consumption is high. Moreover, the stirring device is driven and rotated by a single motor, so the energy consumption is also high

[0003] Moreover, the existing flotation machines all have multiple flotation zones with a single feeding trough, resulting in a waste of resources; The drug and the pulp cannot be mixed and reacted effectively and quickly, which delays the time and efficiency of separating minerals
