Description

The invention relates to inkjet technology and can be used for mixing and pumping various media.

The purpose of the invention is to increase productivity.

FIG. 1 shows a device in cross section; in fig. 2 is the same axial section: in FIG. 3 - a general view of the device.

The jet apparatus contains a radial active nozzle 1, an axial nozzle 2 for supplying an active medium and nozzles 3 and 4 for supplying a passive medium and withdrawing a mixture of media, mixing chambers 5 with diffusers formed by two coaxial disks 6 and 7 and spiral curvilinear partitions 8 installed between them and the receiving chamber 9. The apparatus is provided with an additional nozzle 10 for supplying an active medium, chambers 11 with diffusers and an active nozzle 12, made similarly to the main one and arranged coaxially and opposite to them, an additional nozzle 13 retraction and the mixture, a lateral cylindrical wall 14 and a spiral partition 15 installed between the cylindrical wall 14 and the receiving chamber 9, the active nozzles 12 are made multi-barreled, the direction of twisting of the spiral partitions 8 and 15 of the main and additional chambers 5 and 11 of the mixture is opposite, and the nozzles 4 and 13 of the blend are located on the side wall 14 on opposite sides of the spiral partition 15.

Inkjet apparatus operates as follows.

The active medium is supplied through the axial nozzles 1 and 10 to the radial active nozzles 1 and 12, where flat working jets are formed for each mixing chamber 5 and 11. The passive medium is supplied through the nozzle 3 into the receiving chamber 9, from where it is sucked into the space between the working jets. Next, the mixture of media enters the displacement chambers 5 and 11 with diffusers, where further mixing of the media takes place, their velocities equalize and at the same time inhibition of the mixture flow, which is accompanied by an increase in its pressure. From the diffusers, the mixture of media enters the collecting channels 16 and 17, from where it is discharged through pipes 4 and 13 to the consumer, while the direction of movement of the mixture in the collecting channels coincides with the direction of its movement in the mixing chambers, and the cross-sectional area of the collection channels increases.
