(54) FLOTATION DEVICE

I

This invention relates to the irocees of enrichment and beneficial and hazardous.

Information for flotation, in which the pulp enters the chamber through tangeniyalio installed nozzles and holes located opposite each other at different levels to regulate the magnitude of the centrifugal sy.1. The tailings are discharged from the bottom of chamber 1 after the flotation process has been completed.

When installing a number of such chambers, it is difficult to translate the pulp when necessary and religious operations.

The closest to the proposed technical support and the achieved result is a flotation device, which includes a clyidric shaped chamber with openings and tangentially installed branch pipes for inlet and discharge of the pulp, which are different at different heights, opposite to the other 2.

However, such a device has a significant disadvantage in that it has the energy consumption caused by installing its own pump for each chamber.

The purpose of the invention is to reduce power consumption when transferring pulp from chamber to chamber.

2

This is achieved due to the presence of a series of consecutively installed chambers, the inlet and discharge nozzles of which are connected by a pipeline that is tangential to the forming gauge.

FIG. 1 shows the described flotation device, general view; in fig. 2 - the same, npii cascade arrangement of flotation cells; in fig. 3 - the same in terms of.

The flotation device consists of chambers 1 of cylindrical shape with a loading m 2 and

There are 3 discharge ports and tangentially installed nozzles 4 and 5, corresponding to the input and unloading of pulp located at different heights one opposite the other. An air tube 6 is mounted in each chamber, inside which a shaft 7 passes to rotate an impeller (not shown).

Chute 8 is designed to discharge the flotation froth product. The pulp is transferred from the chamber to the chamber through a pipe 9 and an inlet 10.

0

The device works as follows.

A tangentially mounted nozzle 4 is fed through a loading opening 2 into compartment 1 by a flotation pulmonary tank, which, thanks to the tangential entry, receives a rotational movement. When the impeller is operating through the air tube 6, air is sucked into the chamber 1, which is finely dispersed and distributed over the volume of the chamber. / The mineralized air bubbles, when lifted, form a flotation foam product, which is withdrawn into chute 8, and the non-floated part of the product enters the overflow pipe 9 and through the input nozzle 10 - through the outlet 3 and the purge flotation.
