Gas-liquid emulsion generator - for foundry sand hardening agent

摘要

The carrier gas and the liquid to be vapourised comprises two independent circuits and are injected simultaneously into the mixing chamber. The liquid is injected by means of a pistol into the centre of the chamber. The gas is injected by a multiplicity of nozzles arranged radially towards the axis of the chamber and in a plane perpendicular to this axis. The nozzles are branched onto a circular collector which ensures a uniform gas pressure. The proportions of the mix are controlled by valves with time controlled openings. The gas valve is controlled also by a time switch.
