Description

one

The invention relates to inkjet technology and is an improvement to a multi-nozzle ejector according to auth. No. 1054580.

The purpose of the invention is to intensify the process of mixing media.

The drawing shows multi-nozzle ejector, longitudinal section.

The multi-nozzle ejector includes a housing 1 with active nozzles 2 installed therein, coaxially with each of which the mixing chamber 3 and the diffuser 4 are located, and the mixing chamber 3, and the diffuser 4 are located at an acute angle c6 to the axis of the housing 1 along the flow direction, each input section The mixing chamber 3 is displaced relative to the outlet section of the diffuser 4 in the circumferential direction. The mixing chambers 3 with diffusers 4 are mounted in the housing 1 rotatably around its axis. The ejector additionally contains two half-crowns 5 and 6, interacting with each other piezoelectric elements 7 and 8, and the half-weight 5 is installed at the outlet of the diffusers 4 with the possibility of rotation with them and the location of wives at the inner surface of housing 1, and the half-wedge 6 is fixed on the latter.

The active liquid medium, having flowed out of the nozzles 2, carries the passive medium into the mixing chamber 3. In diffusers 4, the kinetic energy of the mixture flow is partially converted into potential energy. Due to the inlet cross section, the mixing chambers 3 are displaced relative to the outlet cross section of the diffuser

4 in the circumferential direction, the flow of the mixture of media at the outlet of the diffusers 4 is twisted, which leads to rotation around the axis of the chamber body 3 of the mixture with the diffusers 4 with respect to the active nozzles 2. At the same time the flow of the mixture of media from the diffusers 4 flows into the piezoelectric elements 7 8, which causes the generation of energy in the latter, and as a result of the rotation of the piezoelements 7 around the circumference, at the time of the alignment of the piezoelectric elements 7 and 8, the energy accumulated by them is in the form of electric discharge.

15, the piezoelectric elements 7 and 8 are again affected by the flow pressure from the diffusers 4, and the charging process and the subsequent discharge of the piezoelectric elements 7 .and 8 is repeated.

Thus, by conducting electrical discharges in the flow of the mixture of media, it intensifies the process of their mixing.
