Abstract

FIELD OF THE INVENTION The invention relates to the flotation of minerals. The purpose of the invention is to accelerate the transportation of the froth product due to its more efficient destruction. The device comprises a drain chute 1 with an inclined bottom 8, an overflow threshold 2 and an outlet nozzle 3, on top of the groove 1 is closed by a lid 4. Inside the chute 1 is a package 5 of plates 6 with openings 7 inclined to the nozzle 3. The plates 6 are installed with gaps relative to the lid 4 and bottoms 8 are perpendicular to the latter. Spikes 9 are made on the surface of the plates 6 opposite to their inclination. The diameter of the holes 1 decreases from top to bottom. The foam product from the flotation machine is poured over the threshold 2 into the chute 1 where it contacts with the bag 5. When air bubbles hit the surface of the plates 6 and the spikes 9 they are destroyed. Unbroken bubbles pass through the holes 7. Deforming in this way, which contributes to their destruction, and collides with the next plate 6 of the package 5, the stripped product accumulates at the bottom 8 and is removed from the nozzle 3. 3 Il, 6 C, 5 7 ) 00 was eating about

Description

FIG. 7

The invention relates to the enrichment of minerals by the flotation method, in particular, to devices for its implementation, and can be used in the processing of ore or non-metallic raw materials.

The purpose of the invention is to increase the efficiency of destruction of the froth product and accelerate its transportation.

FIG. 1 shows a device for breaking a froth product fixed on board a flotation machine, a transverse vertical section; in fig. 2 - the same, its frontal view is shown; in FIG. 3 a section A-A in FIG. one.

The device for destruction of the froth product of the flotation machine consists of a drain chute 1 with an overflow threshold 2 and a discharge pipe 3. On top of the drain chute 1 is closed with a lid 4. Inside the drain chute 1 is a package 5 inclined to the discharge pipe 3 of the plates 6 with holes 7 installed perpendicular The inclined bottom 8 of the drain chute 1 with gaps relative to its inclined bottom 8 and the cover 4. The diameter of the holes 7 in the inclined plates 6 decreases from top to bottom. The spikes 9 are made on the surface of the inclined plates 6 opposite to their inclination. The inclined plates 6 are fastened to the walls of the drain chute 1 with the help of strips 10.

A device for breaking the froth product of a flotation machine works as follows.

The foam product from the flotation machine, overflowing overflow threshold 2, enters the discharge chute 1 and moves to nozzle 3 to remove it: As the foam moves along the groove 1, air bubbles hit the surface of the spiked plates 6 and collapse. Unbroken bubbles,

the passage through the holes 7 in the plates 6 and the gaps between the plates b, the bottom 8 and the lid 4 meet with the surface and the spikes 9 of the next inclined plate

6, where the foam breaking process continues. When passing through the holes 7 of the plates b, the air bubbles are partially deformed, which contributes to their destruction. The secured product accumulates

the bottom 8 of the chute 1 and moves to the nozzle 3, where it is removed from the chute 1. Repeated contact of the foam product with the surface of the inclined plates 6, spikes 9, as well as repeated passage of bubbles through the holes 7 promotes its rapid extinguishing, which eliminates the loss of the useful component an account of its shedding from foam into the chambers of a flotation machine during the overflow of the drainage chute. If necessary, in order to accelerate the quenching of the foam in the discharge chute 1, a reduced pressure is created.
