In the foam generator of vortex type the sprayer is connected to the housing of an ejecting nozzle made in the form of a diffuser mounted axially relative to the sprayer axis. On the housing of the ejecting nozzle in a part located closer to the sprayer at least three windows for ejecting air are made. Inside the ejecting nozzle by at least three spokes rigidly connected to the housing of the ejecting nozzle a dissector of two-phase flow in the form of a truncated cone, made of grid or perforated material is fixed. The smaller base of the cone is directed towards the sprayer, and the larger - towards the cut of the diffuser. The housing of the sprayer consists of two coaxial interconnected cylindrical sleeves. One of the sleeves has a larger diameter and the other - the smaller diameter. Inside the sleeve of smaller diameter, coaxially to it a screw is located, which is pressed into it. The outer surface of the screw represents a helical groove. Inside the screw an opening with a screw thread is made. In the sleeve of greater diameter, coaxially to it, a fitting is located, rigidly mounted in it by a threaded connection through the sealing gasket. Inside the fitting a cylindrical opening is coaxially passing into axially located diffuser, which is connected to the cylindrical chamber. The cylindrical chamber is formed by the inner surface of the sleeve of smaller diameter and the end surface of the screw. |
