Description
The chlorine dosing is controlled in alternating cycles with the acid and is monitored.
The illustrated dosing hopper (10) is attached inside the plastic housing and is used to dose the chlorine
granulate into the dissolving and flushing unit (14).
The dosing appliance consists of the dosing hopper (10) with a capacity of approximately 5 kg or 15 kg
and the dosing unit, which comprises the dosing motor (23) with flange, the dosing screw (27), the
motor bracket (24) and the heated dosing pipe (28).
The heating of the dosing pipe prevents the condensation of water vapour, which could lead to a dos-
ing blockage. The dosing unit is screwed into the bottom of the dosing hopper.
The dosing hopper is either closed tightly with the lid, or the filling appliance is used. With the filling
appliance, a chlorine bucket can be placed directly on the dosing hopper, see Figure 5.
For maintenance work on the dosing, the dosing appliance is completely removed from the housing by
lifting it upwards.
The dosing screw (27) transports the calcium hypochlorite granulate from the dosing hopper into the
flushing pipe (38) of the underlying dissolving unit. A solenoid knocker (25) 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 across the dosing screw.
