<p>End regions of the dosing nozzles (11-18) leading into the mixing chamber (10) are inclined with respect to the main longitudinal axis (L-L) of the chamber, through an angle (alpha ). Nozzle outlets (11A-18A) are arranged at the edge of the main nozzle (A), which lies ahead of and points into the mixing chamber. They are located in an annular shoulder (RS) formed by an enlargement (QA) of the chamber cross section. All dosing nozzles are inclined at the same angle, or their angles differ. Nozzle axes do not intersect the main axis. alpha is 20[deg]-65[deg]. Nozzle diameter is 3-7 mm. A channel (30) connects the nozzle inputs, to supply flocculant. The first section includes the main nozzle (A); the second section (B) is for inoculation and includes the mixing chamber, nozzles the connecting channel. The channel (30) is in the form of a groove; it is completed when the plastic halves (A, B) are assembled by welding, adhesion and/or screwing together. An inlet connection (19) for flocculant is provided.</p> |
