SU1523169A2 - Generator of emulsions - Google Patents

Abstract

This invention relates to the beneficiation of minerals. The goal is to stabilize the dispersed composition of the emulsion reagents due to their additional dispersion. The emulsion generator contains a mixing chamber (K) 1, into which liquid and flotation reagents, respectively, are fed through the pipes (P) 2 and 3, respectively. An ejector 4 is located at the end of P3. In the chamber 1, on the side opposite to P 2 and 3, there is an insert 5 with a vortex K 6 and a central opening 7. On the other side of the insert 5 there is a diffuser 8 with openings 9. A movable Gland stem 10, on the end of which, facing liner 5, is made of K 11 in the form of a toroid. The liner 5 together with the stem 10 forms an annular nozzle 12 extending into the K 13 emulsion distribution. The body of the liner 5 is made of toroidal cavities 14. Reagents, the exit from the ejector 4, hit the body of the liner 5 and dispersed into small droplets, which, mixed in K1 with liquid, are compressed in K 6, pass through the hole 7 and through in K 13, from where, through the openings 9, the emulsion of reagents enters the flotation. 4, ejector axis is offset relative to the axis of the liner 5 on the value determined by the expression I = S / ^L.

The invention relates to the enrichment of mineral resources, in particular, to the process for the preparation of flotation reagents, to the process of flotation, and can be used in the processing of ore and non-metallic raw materials.

The aim of the invention is to stabilize the dispersed composition of the emulsion of agents due to their additional dispersion.

The drawing shows the generator multicia.

The emulsion generator consists of a mixing chamber t, into which the branch pipe 2 for supplying liquid and the patent of 5 cuttings 3 for the bottoms of reagents, at the end of which an ejector is located, exit. On the side opposite to nozzles 2 and 3, the mixing chamber 1 includes an insert 5 with a vortex chamber 6 and a central opening 7. On the other side of the insert 5 is a diffuser 8 with openings 9. A movable pressure rod 10 is located along the axis of the diffuser 8 , at the end of which, facing liner 5, is made a chamber 11 in the form of a toroid. The liner 5, together with the gland stem 10, forms an annular nozzle 12 extending into the emulsion distribution chamber 13 located between the diffuser B and the insert 5.

For better dispersion of the reagents, toroidal cavities are made in the body of the liner 5. The ejector axis 4 is displaced relative to the axis of the insertion 45. Step 5 by an amount proportional to the ratio of the base area of the vortex chamber 6 of the liner 5 facing the ejector A to the circumference of the central hole 7 , 50 defined by

K X - the circumference of the central hole 7, m; resistance to counter flow at the entrance to the vortex chamber 6, K 0-2280 mm water; the resistance of the annular nozzle 12 to the movement of the stream, X 0-2500 mm water.st. The emulsion generator works as follows.

Liquid is supplied to the mixing chamber T through nozzle 2 and at the same time flotation reagents are fed through nozzle 3 there, which, coming out of nozzle 3 through the ejector, will hit the body of the liner 5 and disperse into small drops. Drops of the reagent mixed with liquid are compressed in the vortex chamber, as the mixture moves along the generator and through the central hole 7 and the annular nozzle 12 form an emulsion entering the distribution chamber 13, from where emulsion enters the flotation through the holes 9 of the diffuser 8. The displacement of the axis of the ejector k relative to the axis of the insert 5 allows additional dispersion of the reagents due to their impact by the wall of the vortex chamber 6, the optimum resistance to the flow entering the annular nozzle 12 is created from the displacement bodies of the movable gland rod 10, and the optimum value of the resistance to movement The flow of liquid and reagent at the entrance to the vortex chamber 6 is determined by the flow rate and pressure of the liquid and reagents entering the mixing chamber 1.
