Description

The invention relates to the mining industry and can be used in the processing of various liquid media requiring uniformity of mixing and activation, for example cast hardening filling mixtures.

The closest in technical essence and the achieved result is a hydrodynamic generator for processing liquid media, including with a jet-forming nozzle, elastic plate resonators mounted in a casing and equipped with a mechanism for regulating the natural frequency of oscillations (A.S. USSR No. 1498992, C. F 15 B 21/12, 1987).

The disadvantage of this generator is the complexity of the device for controlling the oscillation frequency of the resonator plates.

The aim of the invention is to simplify the device mechanism for controlling the oscillation frequency of the resonator plates,

To this end, according to a known generator including a housing with a jet-forming nozzle, elastic resonator plates mounted in a cantilever body and equipped with a mechanism for controlling the natural frequency of oscillations, the frequency control mechanism of the resonator plates is made in the form of a set of brackets mounted on retractable rods along the length of the case, which are installed in the plane of the resonator plates from their lateral sides with the possibility of clamping the edges of the plates with brackets when extending the rods.

In FIG. 1 shows a vertical section along the axis of the pipeline; in FIG. 2 - profile section along the axis of the pipeline: in FIG. 3 is a complex section AA of a stationary mount for resonating plates.

The hydrodynamic generator consists of a housing 1, in which there are viewing windows 2 and resonating plates 3 are placed, which are rigidly fixed in the fixed mounting unit 4, with mounting bolts 5. The resonating plates 3 have clamps 6 to adjust the stiffness of the resonating plates relative to the stationary mounting unit 4. On both sides of the housing 1, housing covers 7, 8 are installed in the upper housing cover there is a jet forming nozzle 9 with its installation unit

10 and a fixing washer 11. The covers of the housing 7, 8 are attached to the housing with bolts 12. The inspection windows 2 are installed in the inspection nodes 13, The rigidity fixing unit of the resonating plates 6 can be made in the form of a worm mechanism.

A hydrodynamic generator is used as follows.

When transporting a liquid medium, for example, cast filling mixture into underground mine workings by gravity, a generator is installed in the lower part of the vertical pipeline stand or in its horizontal section. When a high-speed jet moves through the pipeline, it runs into the calibrated openings 9, where the pressure in the mixture increases spasmodically due to a decrease in the discharge diameter. In this case, the passage speed increases and, at the exit from the calibrated hole, the mixture interacts with the resonating plates 3.

Given the significant turbulence of the jet behind the hole and its high speed, the resonating plates begin to track

to fight. In order to select the optimal mode of processing the mixture, the rigidity of the resonating plates is regulated by the clamp brackets 6. Before applying the liquid bookmark, the generator is put on standby, for which all rows of control brackets 6 are tightened, then a bookmark is fed, operation is monitored through window 2 generator, control is carried out by loosening the clamps of the clamps 6 and by boiling the mixture over the entire area of the viewing window it is considered that the generator is in working condition.

A hydrodynamic generator can be used in flotation machines to enrich the mineral. In this case, a water-air mixture is passed through a generator, where air bubbles are crushed to a predetermined size, and then the water-air mixture with pulp enters the flotation chamber. The regulation of the elasticity of the resonator plates provides the possibility of producing a water-air mixture with bubbles of optimal size.

A hydrodynamic generator can be used to process media in various industries.
