A device for adding lime to acidulated flowing water including a feed hopper and an endless belt conveyor arranged below the feed hopper. The belt conveyor is driven via a one-way clutch of an arm that is, in turn, driven by a tilting movement of a vessel. The vessel is so journaled that when it has been filled with water to a certain level, it tilts forward, allowing the water to stream out of the vessel. At each tilting movement, a chain coupled to the arm drives the conveyor a distinct stretch forward. When the water has left the vessel, a counterweight makes it tilt upwards again, to be filled again. The water is delivered from the stream in proportion to the flow in the stream, for instance by means of a chute starting in a defined cross-section of the stream. The water from the tilting vessel is lead to a solution chamber wherein baffles extending down from above and up from the bottom force the water to stream turbulently upwards and downwards on each tilting of the vessel, securing good solution of the lime before, the line is allowed to leave the solution chamber, together with the water that is led into the stream downstream of the inlet to the chute. |
