The dosing device consists of the dosing hopper (23) installed on the chlorine drum and the
dosing unit. The latter consists of the dosing motor with flange (29), the dosing screw (25),
the motor bracket (28) and the heating pipe (26).
The heating of the dosing pipe prevents the condensation of water vapour, which could lead
to a dosing blockage.
The dosing screw (25) conveys the calcium hypochlorite granulate from the Dosing hopper
(23) into the flushing pipe (34) of the underlying dissolving unit. A Solenoid knocker (30) is
installed for breaking up the chlorine granulate; during each dosing process, the solenoid
knocker delivers a short blow to the dosing hopper, thus preventing the granulate from
bridging over the dosing screw.
The chlorine dosing is organized in alternating cycles with the acid and is monitored. See
