Polyelectrolyte preparation station SPP series

The automatic station for preparation in continuous of solution of polyelectrolyte, is a machine to use in the processes of mechanical dehydration of the sludges obtained from dewatering machines. Product in powder, before being used for flocculation of sludge to treat, must be diluted in water in such a way to obtain the title of dehydration desired and must be subjected to a process of maturation enough long (min 30/40 minutes). Polyelectrolyte in powder is loaded inside a hopper equipped with dosing screw, which transports the product to hydrate through a heated piping, permitting it to fall on the device for water diffusion. The hydrated product is diluted in the first sector by the first mixer then, by the siphon system, it enters into the second sector. In this sector, which is equipped with mixer at low rotations, there is maturation of solution. Through the second siphon, solution goes into the third sector, where there are an additional maturation and also stocking of product ready to be pumped in the line. In the third sector, when required, can be installed both a third mixer and the pump to extract the poly ready. By level feelers, system of preparation is automatic. Feelers start and stop preparation, when station is completely full in the three sectors. Adjustments of preparation are realized partly distributing flow of dilution water and/or basing capacity of dosing screw, acting on motovariator. Structure is completely made in bended pressed plate in AISI 304 with edges bended inside, to stiff the structure itself. Partition baffles in bended and stiffened plate, which act as siphon of passage for the solution.
