Equipment for foaming of building material - comprises means for installation in material transport conduits with devices for feed of foam-forming additives

摘要

The equipment comprises a pipe piece (4) insertable between pipe sections (1, 2) and connectable to them by a pipe coupling, the end sections of which have the same internal dia. as the adjacent pipe sections (1, 2) and which has a nozzle-shaped narrowed section with grooves (5) inclined to the axis and intermediate fields (6). In the fields, holes (7, 11) are provided for the feed of gas or air and/or a foaming medium or foam material. The holes issue into axially displaced outer periphery grooves (8, 12), to which the feed conduit (10) for gas or air and that (14) for the foaming medium or foam material are connected. The pipe piece (4) inserts in a sealed fashion in a pipe coupling socket (18) which engages over the end section of the adjacent pipe conduit section (1, 2). USE/ADVANTAGE - A simply formed, easily insertable and exchangeable device for placing in a pipe conduit, permitting homogeneous mixt. of building material with a foaming medium or foam material.
