Mineral Flotation Machine

Abstract

The invention discloses a mineral flotation machine. A movable barrel body is provided with a strip-shaped hole and a cofferdam; the cofferdam is provided with a foam material outlet; a fixed barrel body is provided with a small cofferdam; a hollow spindle can rotate and is provided with a vent hole and a blade; the movable barrel body is connected with a screw rod; the screw rod is provided with a rotary handle; a screw rod sleeve is arranged between the rotary handle and a table top; the rotary handle is rotated so as to regulate the height of the movable barrel body; the fixed barrel body is of a tapered bottom structure; the hollow spindle also serves as an air guide pipe and extends to the tapered bottom of the fixed barrel body; a turntable fixed by the hollow spindle is provided with an inner-layer elastic nylon movable brush and an outer-layer elastic nylon movable brush which are annularly arranged; a rib plate, a cylinder, a shaft sleeve rib plate and an elastic nylon fixed brush fixed by a shaft sleeve are arranged between the two layers of elastic nylon movable brushes. The mineral flotation machine is simple and reliable in system structure, low in cost, and efficient and rapid in floatation; the foam spillage height is adjustable, so that the mineral separation precision is convenient to adjust; by virtue of turbulence and foaming reinforcement floatation, the elastic nylon brushes are efficient, have a strong self-cleaning effect and can not be blocked.

Description

technical field [0001] The invention relates to a mineral flotation machine, in particular to a machine for flotation according to the affinity between minerals and medicament foam. Background technique [0002] Flotation is a method of sorting according to the difference in the surface physical and chemical properties of mineral particles and the difference in mineral floatability. Most ores can be sorted by flotation, such as coal, coal fluorite, talc and other non-metallic ores, especially for lead, zinc, molybdenum, mercury, copper and other metals and oxidized ores. [0003] Flotation is a beneficiation method based on the different wettability of minerals by water; minerals with low affinity to water and difficult to be wetted by water are especially suitable for flotation. The use of suitable flotation agents to treat ore powder can change the flotation of minerals. The purpose is The minerals to be flotation can be selectively attached to the air bubbles to form sor...

AI Technical Summary

Problems solved by technology

[0004] Existing mineral flotation machines mainly adopt mechanical agitation, but there are the following defects: first, the overflow height cannot be adjusted generally, and the overflow height is closely related to the flotation precision, so it is not convenient to adjust the flotation precision; The advanced flotation machine lacks the strengthening effect on the foaming and mixing during the mineral flotation process, so the beneficiation efficiency is low, the time is long, and the reagent consumption is large; the third is that the fixed bucket for stirring is often a flat-bottomed structure. After the flotation, the remaining pulp is discharged. The speed is slow, or although the fixed barrel is a cone-bottom structure, it is easy to block

Therefore, the existing mineral flotation machines cannot meet people's needs for mineral processing and need to be improved
