Automatic polyelectrolyte preparation systems


Construction Features • Variable capacity powder dosing unit, hopper with powder level indicator, worm screw with bridge breaker scrapers • Water inlet and regulation unit, solenoid valve, pressure switch, disperser • Preparation tank with covers, divided into the three sectors of dissolving, maturing and storage • Control and command electrical switchboard including the automatisms and indicators for fully automatic plant running • Solution dosage system, generally consisting of dosing pumps selected from the numerous versions available from our range (ask for the specific catalogue)		Function The preparation tank is divided into three sectors: dissolving V1, maturing V2 and storage V3, interconnected by siphons that form a preferential path necessary for the formation of a top quality solution. The powder from the dosing unit comes into contact with the water, which, appropriately sprayed, from a nozzle, carries out the important action of dispersion. The water/powder mixture then drops into the tank below where the dissolving phase begins. In dissolving sector V1 a slow agitator keeps the contents of the tank in movement, thus favoring homogenization of the solution. The siphon transfers the solution to the maturing sector V2 where another slow agitator keeps it homogeneous until maturing is complete.Then the solution is transferred to storage sector V3 from which it can be transferred for use.The level switches installed in this sector control plant automatic functions: High and normal level switch: when the solution reaches the high level this switch stops the powder dosing unit and closes the water inlet solenoid valve.In the normal level position it enables dosing unit functioning and opens the water solenoid valve. Low level switch: when the solution falls to minimum level this switch stops the dosing pump and lights up an alarm indicator on the electrical switchboard.
Automatic functioning Separate regulation of water and powder Stainless steel construction Compact size Ready to be anchored to the floor if required No foundations necessary
