Abstract

The utility model relates to an ore beneficiation device, particularly to a flash flotation machine which is mainly used for nonferrous metals and gold mines. The device comprises a transmission mechanism, an agitating mechanism, a groove body, and an inflatable device. The utility model is characterized in that a false bottom and a steady flow plate are arranged at the bottom part of the groove body, so as to enable the pulp in the groove to circulate in a fixed flow mode. Therefore, the pulp can be enabled to pass through the inflatable area many times so that the flotation chance is increased and the mineral particle suspension is facilitated. In addition, the section of the mixing impeller is a whirl structure, thereby enabling the surface area used for dispersing air to be increased and being beneficial to the dispersion and thinning of air in the pulp.

Description

A kind of flash flotation machine

Technical field

The utility model relates to a kind of mine preparation equipment, particularly a kind of flash flotation machine that is mainly used in non-ferrous metal and gold mine.

Background technology

Flash flotation machine is a kind of floatation equipment in advance, is used for the ore dressing plant and handles cyclone sand setting or other coarse grain and high concentration material.Flash flotation machine is separated different mineral selectively by means of stirring, disperse and inflation, and by disperse air in liquid, the realization ore pulp fully mixes with air.The chemical agent that adds forms hydrophobic layer selectively on the flotation ore particle.Countless minute bubbles produce when air mixes with liquid.The hydrophobicity ore particle is attached on the bubble and is taken to liquid level, is scraped collection then.But traditional flotation device ubiquity ore pulp is not enough through the number of times in qi of chong channel ascending adversely district, causes the ability and all not high enough problem of precision that sort.

The utility model content

The technical problem that the utility model need solve is: the ability and the not enough problem of precision that sort at traditional flotation device, and provide a kind of ability of sorting strong flash flotation machine.

The technical scheme that the utility model adopted: it comprises parts such as transmission mechanism, rabbling mechanism, cell body, qi of chong channel ascending adversely device, is provided with the false end and stabilier in the bottom of cell body.

The section of agitator arm is a swirl shape in the rabbling mechanism.

The beneficial effects of the utility model: the utility model with said structure is because of the false end and stabilier are set in the cell body bottom, the interior ore deposit of groove is fallen by the fixing type of flow carry out systemic circulation, this has just guaranteed that ore pulp repeatedly by the qi of chong channel ascending adversely district, has increased the grading machine meeting, and helps the ore particle suspension.The section of agitator arm is a swirl shape, makes the surface area of dispersion air big, helps air and disperses and refinement in ore pulp.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the front view of the utility model rotor;

Fig. 3 is the vertical view of the utility model rotor.

The specific embodiment

Referring to Fig. 1, the utility model comprises parts such as transmission mechanism, rabbling mechanism, cell body, qi of chong channel ascending adversely device, wherein is provided with the false end 2 and stabilier 3 in the bottom of cell body 1.Rabbling mechanism has comprised rotor 4 and stator 5.Because the false end 2 and stabilier 3 are set, can make ore pulp repeatedly by the qi of chong channel ascending adversely district, increased the ability and the precision that sort greatly.

Referring to Fig. 2, Fig. 3, the section of agitator arm is a swirl shape as seen from the figure, makes the surface area of dispersion air big, helps air and disperses and refinement in ore pulp.And impeller of the present utility model and stator be line with rubber all, can prolong its service life.

In addition, the utility model also has following features:

1, impeller height height, blade area are big, in the situation that does not increase power consumption, have enough stirrings Ability.

2, the gap between impeller and the stator is big, and this can reduce the wearing and tearing of impeller and stator, also can reduce electricity Can consume.

Operation principle of the present utility model is: when transmission mechanism turned round, compressed air advanced by hollow shaft Enter the agitator arm to the bottom, the air that enters is along with the rotation of impeller, and discharge in the hole from blade, logical Cross disperse air in the liquid, form minute bubbles, these minute bubbles are by rotor and the stator of rotation, and are fast Speed is broken up, and reaches and fully mixes from the bottom ore pulp. The hydrophobicity ore particle is attached on the bubble and is taken to Liquid level is raised to then foam tank and scrapes collection, and underflow is discharged from the cell body bottom.

Claims

1, a kind of flash flotation machine comprises transmission mechanism, rabbling mechanism, cell body, qi of chong channel ascending adversely device, it is characterized in that: be provided with the false end and stabilier in the bottom of cell body.

2, a kind of flash flotation machine according to claim 1, the section that it is characterized in that agitator arm in the rabbling mechanism is a swirl shape.
