The invention relates to building materials and can be used for the production of cellular concrete and porous solutions.

The purpose of the invention is to improve the quality of the foam.

The drawing shows a device for preparing a technical foam, a general view.

A device for making foam contains interconnected pipe I for supplying a foaming solution, pipe 2 for supplying a component for dispersing the foaming solution in the form of compressed air and a pipe for forming a foam containing two successive pipe-chambers, one of which is the entrance chamber 3 The grids 4 disposed therein, the other chamber is the dispersion chamber 5, which can be made, for example, of rubberized hose and filled with stainless steel 6 metal chips.

A foam pipe 7 is connected to the dispersion chamber 5. The mixing chamber 3 is connected to the dispersion chamber 5 by means of an adapter 8.

The dimensions of whose metal grids 4, which are made of stainless steel, are selected depending on the required characteristics of the foam being prepared, for example, with a density from 10 to 120, resistant to 1 hour, and a particle size of 10-140 microns.

The implementation of the dispersion chamber 5 in the form of a hose ensures the immobility of metal chips due to the forces

coupling arising between the chips 6 and the walls of the hose.

A device for the preparation of technical foam works as follows.

In the nozzle 1 under pressure with different costs enters the 3% solution of the frother PO-1. From the pipe 1, the foaming solution is fed into the inlet displacement chamber 3, where simultaneously

through the pipe 2 enters compressed air with a flow rate that provides the required ratio of foam. Moving in chamber 3, the mixture of foaming solution with compressed air passes under pressure through metal grids 4. Next,

The mixture in the form of foam enters the dispersion outlet chamber 5 with stainless steel metal chips 6, where the foam is further dispersed. After that, the foam is already prepared via the foam pipe 7 and goes to a mixer (not shown) to prepare a porous solution.
