Technical Field

The utility model relates to a flotation column technical field specifically indicates a foaming device is used to flotation column.

Background

The flotation column is an inflatable flotation machine which inflates and stirs ore pulp by compressed air through a foaming device. The flotation column has the characteristics of simple structure, low energy consumption, small occupied area, easy operation and control, suitability for treating micro-fine mineral, but easy scaling and blockage of the aerator.

The invention provides a flotation column airflow foaming device which comprises a flotation column body, wherein the bottom of a shell of the flotation column body is conical, and the flotation column airflow foaming device is structurally characterized in that a hollow shaft is arranged in the center of the bottom of the flotation column body, a conical hollow body is arranged outside the hollow shaft, the top of the hollow shaft is provided with a flow distribution cap, a V-shaped injection pipe is arranged outside the flow distribution cap, and a spray head is arranged on the V-shaped injection pipe. Although the invention can realize the foaming of the flotation column, the anti-blocking performance is poor because of impurities on the straight surface of the spray head from top to bottom, and the spray pipe is easy to lose sand and stone when rotating at high speed and is not durable.

There is a need for improvement.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a foaming device for flotation column that is difficult for blockking up, the foaming is even, simple durable.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: this design foaming device for flotation column, it uses the cooperation with flotation column barrel, including the filter screen, the filter screen is fixed to be located in the flotation column barrel, be equipped with rotary joint on the filter screen, rotary joint includes inner tube and outer tube of relative rotation, the inner tube runs through perpendicularly the filter screen just sets up with the filter screen is fixed, the inner tube passes through pipeline intercommunication high pressurized air source, a plurality of blades of the even rigid coupling of circumference of outer tube, the circumference of outer tube evenly is equipped with a plurality of through-holes, the end-to-end connection sealing flange of outer tube, the fixed motor that is equipped with in bottom surface of flotation column barrel, the pivot and the coaxial rigid coupling of sealing flange of motor. This design utilizes the rotary joint who inverts, and it is that foaming gas can follow the through-hole blowout of outer tube, and the motor can drive the blade rotation, realizes even foaming.

Further, the through holes are arranged at the lower ends of the blades on the outer pipe, so that the bubbles can automatically float upwards depending on the density and can be further dispersed and foamed through the blades.

Furthermore, the rotary joint is a multi-way rotary joint, and an inner pipe of the rotary joint is simultaneously communicated with a high-pressure gas source and a high-pressure liquid source through a pipeline. The rotary joint can be simultaneously connected with a high-pressure air source and a liquid source of the foaming agent, so that gas-liquid mixing foaming is realized.

Further, the screen completely covers the cross section of the flotation column cylinder.

Further, the filter screen is a rigid screen.

Furthermore, the aperture of the mesh of the filter screen is 5-10cm, so that the blade is prevented from being lost by overlarge sand and smaller sand can be changed into tailings to be discharged.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model utilizes the inverted rotary joint, and bubbles are led out through the rotary joint, thus having better anti-blocking performance to the sand stone moving from top to bottom; the rotating blades can play a role in uniform foaming; the filter screen can prevent too big grit from to blade and rotary joint's damage, and is comparatively durable.
