Description

The invention relates to devices for creating acoustic oscillations in a flow medium and can be used in various industries to carry out physicochemical processes: dispersing emulsification, etc.

The aim of the invention is to expand the technological capabilities of the device for creating acoustic vibrations in the flow medium and to simplify the design.

FIG. 1 shows the proposed device, the cut; in fig. 2 shows section A-A in FIG. 1 (plugs are installed in each radial hole of the stator in a position where the holes of the stator communicate only with the sound chamber); in fig. 3 - the same, the plugs are installed. In the position that blocks the output of the radial holes in the sound chamber; in fig. 4 - the same, a part of the stator holes is not connected to the axial channels and there are additional radial holes in the stator connected to the axial channels; FIG. 5 is a section BB in FIG. 3; in fig. 6 - the position of the rotary tube, partially blocking the hole in the stator

The device for creating acoustic oscillations in the flow medium contains a cylindrical case I with nozzles 2 and 3 for supplying and discharging the working medium mounted rotatably from a drive (not shown) hollow rotor 4 having blades 5 and a stator 6 separating the body cavity 1 for two chambers 7 and 8 - working and dubbing.

On the cylindrical surfaces of the pOTOgOB 4 and the stator 6 there are through radial holes 9 and 10. Through channels I1 are made in the stator 6, which are connected to its radial holes Yu and the working chamber 7. Rotary plugs 12 are installed at the junction points of the holes 10 and channels 11 with groove 13.

In addition, in the stator 6 from the side of the rotor 4 made additional radial holes 14, directly connected to the channels 11.

An embodiment is possible in which through radial through holes 15 are additionally made, which directly extend into the sound chamber 8.

The device works as follows.

Depending on the mode of operation of the device, various installation positions of the rotary plugs 12 are possible. The plugs can be set to the position when the axial channels 11 are blocked and the holes 10 of the stator 6 communicate with the sound chamber 8 or when the connection of the holes 10 of the stator 6 is blocked with the camera B, and the holes 10 communicate with the channels 11 and through them with the working chamber 7. The intermediate position of the plugs 12 is also possible when the hole 10 of the stator 6 and the slot are partially blocked

the stator 6 is smaller than the hole G of the stator

AT

Before starting operation, the rotatable plugs 12 are installed in a position that overlaps the channels J1.

The working medium enters tangentially through the nozzle 2 into the working chamber 7, from where it is injected with blades 5 into the hollow rotor 4 and when the holes 9 of the rotor 4 and the holes 10 of the stator 6 coincide with a pulsating flow into the sound chamber 8.

If the exit of a part of the holes 10 of the stator 6 into the sound chamber 8 is blocked, and the other part of the holes 10 communicates with the channels 1I, the device operates as follows.

A portion of the working medium is pulsed through the holes 10 of the stator 6 into the sound chamber 8 and from there through pipe 3 to the consumer, and the other part of the pulsating flow enters the working chamber 7 through axial channels 11, where it acts on the working medium and the working is repeated by recycling it in the same device. The continuous part of the product arrives to the consumer. Maximum performance mode is possible with a relatively short dispersion time.

When operating with a maximum processing time, most of the holes 10 of the stator 6 communicate with the working chamber 7, and the outlet to the chamber 8 y. most of the holes 10 are blocked by plugs 12. This mode is necessary in order to obtain a high degree of dispersion.

When fine adjustment of the system is necessary (processing time, proizA-A
