Flotation column disc type spraying device

Abstract

The invention relates to a flotation column disc type spraying device. The flotation column disc type spraying device comprises a column body (1), wherein an inner overflow groove (2), a middle overflow groove (3) and an outer overflow groove (4) are sequentially formed in the top of the column body (1) from inside to outside; a concentrate outlet (5) is formed in the outer overflow groove (4); awater disc support (6) is arranged at the top of the outer overflow groove (3); an annular inner water disc (7), an annular middle water disc (8) and an annular outer water disc (9) are sequentially arranged on the water disc support (6) from inside to outside. The outer water disc (9) is correspondingly arranged in the area between the outer overflow groove (4) and the middle overflow groove (3),the middle water disc (8) is correspondingly arranged in the area between the middle overflow groove (3) and the inner overflow groove (2), and the inner water disc (7) is correspondingly arranged inthe inner area of the inner overflow groove (3). According to the flotation column disc type spraying device, the uniformity of flotation column spraying and cleaning can be greatly improved, and therefore the final cleaning effect is effectively guaranteed.

Description

technical field [0001] The invention relates to a flotation column-disc spray device, which belongs to the technical field of flotation column equipment. Background technique [0002] The equipment on traditional mechanical agitation flotation machines in oil refining, petrochemical, metallurgy, mining and other industries, due to the violent vibration generated by mechanical agitation, is not conducive to the selection of ore particles, especially fine ore particles are more difficult to recover, recycling The efficiency is difficult to improve, and the existing mechanical flotation machines cannot meet the requirements. [0003] An important feature of the flotation column is its foam flushing system. The auxiliary means of foam flushing can remove unnecessary impurities from the flotation foam. The flushing water added from the top of the flotation column is filtered through the foam area to replace the process. Particles trapped by water and air bubbles, in addition, th...
