Phie.1

The invention relates to the enrichment of minerals, namely, apparatus for thickening fine particles of the solid phase, and can be used to clarify circulating waters,

The purpose of the invention is to intensify the process by creating zones of pressure antinodes of an ultrasonic standing wave.

FIG. 1 shows the proposed apparatus, a general view; in fig. 2 shows section A-A in FIG. one; FIG. 3 shows an apparatus with capillary selectors, a general view; in fig. 4 shows a section BB in FIG. 3

The apparatus (Fig. 1) contains a rectangular case 1, an element 2 for supplying a suspension, a receiver 3 of a clarified liquid phase in the form of a nozzle, a receiver 4 of condensed products in the form of slotted shut-off devices. One of the side walls of the apparatus is an ultrasonic wave source - the vibrator 5 and is a metal plate 6 with a sound wave generating element 7 glued to it, and the vibrator 5 do.g can be installed by means of the fixing unit 8 parallel to the opposite wall 9 rectangular housing 1 at a distance that is a multiple of 1/2 of the ultrasound wavelength, together forming an ultrasonic standing wave resonator.

Element 2 for supplying the suspension is equipped with a dispenser 10 for supplying flocculants. Under the influence of an ultrasonic standing water suspension, it is stratified, forming the pressure-antinode zone 11 (thickening zone) and the clarified zone 2.

The apparatus (Fig. 3) is exposed from the apparatus (Fig. 1) in that the receiver 3 of the clarified liquid phase is shaped in the form of capillary selectors 13 of the clarified portion of the suspension located in the clarified zones 12, and the receiver of the condensed products is designed as a nozzle 14.

The device works as follows.

A solution of high-molecular flocculant from the flotation dispenser 10 is added to the process water containing finely dispersed clay-clay particles, after which the process water containing water

the coolant enters through the element 2 for supplying the suspension to the rectangular body 1, which together with the vibrator 5 installed by the attachment unit 8 parallel to the opposite wall 9 of the rectangular body 1 at a distance times 1/2 of the ultrasound wavelength, becomes a resonator, which forms and maintains an ultrasonic wave, under the action of which the suspension stratifies into thickening zones 11 and clarified zones 12. In thickening zones 11, pressure accumulations, which are simultaneously nodes of oscillatory velocity and are collected solids slurry and flocculants macromolecule, whereby the distance between particles and macromolecules become mcd sufficient to react, i.e., a flocculation process occurs and flocculated particles are collected by 4 dryers receivers and removed from the apparatus. The clarified liquid enters the receiver 3 of the clarified liquid phase and is withdrawn from the apparatus for clarifying the suspensions.

If the process of stratification of the suspension occurs under the action of an ultrasonic discharge with the formation of clarified zones 12 and zones 11. of pressure impurity (thickening zones), then the clarified liquid is removed from the apparatus by means of capillary selectors 13 of the clarified part. suspension, and the condensed product is deposited in the receiver of condensed products, made in the form of pipe 14.

The use of the proposed apparatus intensifies the process of lightening the suspension from finely dispersed siliceous-clay particles and improves the quality of the clarified water.

Using the apparatus, any technological liquids can be exposed to clarification, regardless of the concentration of dissolved salts, the solid phase of the suspension can be represented by particles of an arbitrary nature — ferromagnetic, paramagnetic, diamagnetic, etc.

The advantages of the device include low energy demand, since the formation and maintenance of UZSV (due to the fact that it does not transfer energy) does not require powerful energy sources with high energy consumption.
