Abstract
The invention discloses a short flotation column for selecting gold. The short flotation column comprises a flotation column body (1) with a hollow structure; a foam tank (6), a foam overflow groove (7), an overflow pipe (8) and a feeding device (5) are arranged on the upper part of the flotation column body (1); the lower part of an inner cavity of the flotation column body is provided with a foaming device (2); the bottom of the flotation column body is provided with a blow-down pipe (10) and a tailing discharge device (9); and a steady flow plate (3) and an ore pulp dispersion cover (4) are respectively arranged on the upper part of the inner cavity of the flotation column body. The flotation column is shortened, and the steady flow plate of a well and the ore pulp dispersion cover are added, thereby guaranteeing the stability of a liquid level, and being beneficial to improving the treatment capacity and beneficiation indexes of the flotation column.
Description
Technical field
The invention belongs to a kind of floatation equipment, relate generally to the short flotation column of a kind of use and replace flotation device to sort the floatation equipment of gold.
Background technology
Gold sorts the floatations that adopt more, and floatation equipment is with self-priming and pneumatic flotation cell is in the majority, and its power consumption is large, takes up room large, and long flow path, labor strength are large, particularly along with mineral resources are exploited day by day, and the rich ore minimizing, lean ores exploitation is trend of the times.Gold density is large, adopts the conventional flotation post to be difficult to reach floatation indicators.Therefore design a kind of equipment and carry out gold and sort, improve the rate of recovery and concentrate grade imperative.
Summary of the invention
The purpose of this invention is to provide a kind of short flotation column be used to sorting gold, it is rational in infrastructure, can effectively improve disposal ability and mineral processing index.
Purpose of the present invention can adopt following technical scheme to realize: it comprises the flotation cylinder, the flotation column cylinder is hollow structure, be provided with foam tank, froth overflow channel, overflow pipe, feed arrangement on the top of flotation cylinder, the bottom of flotation column intracoelomic cavity is provided with foam device, flotation cylinder bottom is provided with blow-down pipe and mine tailing ore discharge device, arranges on the top of flotation column intracoelomic cavity and is respectively arranged with stabilier and ore pulp dispersion cover.
Described flotation column height is 4-6.5 rice.
Described stabilier is arranged on ore pulp and disperses the bottom of cover.
Described stabilier is well shape, at the inwall of flotation cylinder, fixes.
Described dispersion cover is the umbrella shape face, and its poppet surface is uniformly distributed circular hole.
The present invention sets up well subtype stabilier in the flotation column middle and upper part, can make ore pulp under the effect of foam device, low-density and fine grained mineral are done and are moved upward with cylinder, when control tolerance is excessive, the ore pulp speed that moves upward is aggravated, and is steady for guaranteeing liquid level, adopts and disperse cover to make mineral evenly flow in cylinder, reduce the loss of rising bubble attachment (valuable mineral), improve the rate of recovery.Can make simultaneously and be attached to bubble surface low-density and fine grained mineral process dispersion cover, evenly enter froth bed, thereby make liquid level stabilizing.
In sum, the present invention downgrades, increases well stabilier by flotation column and ore pulp disperses cover, guarantees liquid level stabilizing, thereby is conducive to improve disposal ability and the mineral processing index of flotation column.

The specific embodiment
By reference to the accompanying drawings, specific embodiments of the invention are described.But the present invention is not limited to the following examples;
As shown in Figure 1: the present invention includes flotation cylinder 1, flotation cylinder 1 is hollow structure, and it has cylinder on conventional 8-12 meters bases to be reduced to 4-6.5 rice.Be provided with foam tank 6, froth overflow channel 7, overflow pipe 8, feed arrangement 5 on the top of flotation cylinder 1, the bottom of flotation column intracoelomic cavity is provided with foam device 2, flotation cylinder 1 bottom is provided with blow-down pipe 10 and mine tailing ore discharge device 9, is respectively arranged with stabilier 3 and ore pulp on the top of flotation column intracoelomic cavity and disperses cover 4.Described stabilier 3 is arranged on ore pulp and disperses the bottom of cover 4.
Described dispersion cover is the umbrella shape face as shown in Figure 2,3, and its poppet surface is uniformly distributed circular hole.Dispersion cover structure figure when flotation cylinder shown in Figure 2 is cylinder.Dispersion cover structure figure when flotation cylinder shown in Figure 3 is square cylinder.
Operation principle:Advance slurry by advancing sizing device 5, enter in flotation cylinder 1 by self pressure, foam device 2 externally produces a large amount of bubbles under the compressed air effect, ore pulp fully mixes with bubble in cylinder, the mineralized froth that produces passes through foam tank 6 overflows to froth overflow channel 7, draining into outside body through overflow pipe 8. mine tailing drains into outside body by ore discharge system 9, in order to reach good sorting result, the assurance liquid level is steady, do not produce phenomenon of turning over flower, add stabilier 3 at the middle part of cylinder 1 and disperse cover 4 to reach steady flow result.
Not detailed description part of the present invention is prior art.
