Abstract

EJECTOR, comprising a housing with axial and radial nozzles for supplying active and passive media. a co-fusion mixing chamber and a diffuser with a throat and a central active nozzle and an annular multi-nozzle, successively installed in the housing, communicated by means of tubes with a nozzle for supplying the active medium, characterized in that the tubes are made with plane-parallel walls and are located on both sides from the axis of the housing parallel to the axis of the nozzle supplying a passive medium: (L 00 OS po and -a

Description

I

The invention relates to inkjet technology, mainly to underwater ejector installations for cleaning soil under water.

The purpose of the invention is to increase the performance of the ejector.

FIG. 1 shows the proposed ejector, longitudinal section; in fig. 2 shows section A-A in FIG. 1 in FIG. 3 is a section b-B in FIG. one.

The ejector includes a housing 1 with an axial and radial nozzles 2 and 3 for supplying active and passive media, a confusing chamber 4 mixing and a diffuser 5 with a throat 6, successively installed in the housing 1 a central active nozzle 7 and an annular multi-nozzle 8, communicated by , tubes 9 with a branch pipe 2 for supplying an active medium. Tubes 9 are made with

plane-parallel walls 10 and are located on both sides of the axis of the housing 1 parallel to the axis of the pipe 3 for supplying a passive medium,. The active fluid medium, which has expired from the central active nozzle 7 and the annular multi-nozzle nozzle 8, carries the passive medium (pulp) into the mixing chamber 4. Once in the space between the plane-parallel walls 10, the vortex flow of the passive medium is leveled, and the active medium, having elapsed from the annular multi-nozzle, directs the flow of the passive medium with a small deviation from the axis of the ejector body 1. Next, the flow of the mixture of media enters the mouth 6 of the diffuser 5 and then into the diffuser 5, where the kinetic energy of the mixture of media is partially converted into potential energy.
