Description

The invention relates to inkjet technology, mainly to ejectors for pumping viscous liquids.

The aim of the invention is to intensify the mixing of media.

The drawing shows the described ejector, longitudinal section.

The ejector contains nozzles 1 and 2 for supplying active and passive media, an active nozzle 3, a mixing chamber 4, a diffuser 5 and a central body 6 located in it, the diffuser 5 and the central body 6 being equipped with screw channels 7 and 8. Screw ducts 7 and -8 the diffuser 5 and the central body 6 have Edited A. Vorovich

There are opposing spin directions.

The active medium from the nozzle 1 for supplying the active medium enters the nozzle 3 and, having flowed out of it, carries the passive medium into the mixing chamber 4. In the diffuser 5, the kinetic energy of the mixture of media is converted into potential energy, moreover, the raid on the screw channels 7 and 8 of the diffuser 5 and the central body 6, the peripheral and central parts of the flow acquire the opposite spin, which intensifies the mixing and dispersion of a more viscous passive medium in the active medium .

Claims (1)

EJECTOR, comprising nozzles for supplying active and passive media, an active nozzle, a mixing chamber, a diffuser and a central body located in it, the diffuser and a central body having screw channels, characterized in that, in order to intensify the mixing of the media, the screw channels of the diffuser and the central body have opposite spin directions. c <g (A
