Description

Die Erfindung betrifft einen Zuteiler für Wasserenthärtungsanlagen, bei welchen ein dem Hauptstrom proportionaler Teilstrom des Rohwassers durch den Kalksättiger geleitet wird und bei welchen eine ungeregelte Kreiselpumpe die Kalklösung in den Reaktor drückt, und besteht darin, daß in Abhängigkeit von der Höhe des Wasserspiegels im Kalksättiger ein Teil des Rohwassers der aus dem Kalksättiger abfließenden Lösung zugesetzt wird.The invention relates to a dispenser for water softening systems, in which a partial flow of the raw water proportional to the main flow through the Lime saturator is passed and in which an unregulated centrifugal pump is the lime solution pushes into the reactor, and consists in that depending on the height of the water level in the lime saturator part of the raw water of the solution flowing out of the lime saturator is added.

Die ungeregelt arbeitende Kreiselpumpe macht es notwendig, ihr auch dann genügend Flüssigkeit zuzuführen, wenn der Hauptstrom und damit der Teilstrom des den Kalksättiger durchströmenden Rohwassers abnimmt. Durch die Zugabe eines Teilstromes, dessen Menge der aus dem Kalksättiger kommenden umgekehrt proportional ist, wird der Pumpe genügend Wasser zugeführt und zugleich eine klare Kalklösung erzielt.The uncontrolled working centrifugal pump makes it necessary, you too then supply sufficient liquid when the main flow and thus the partial flow of the raw water flowing through the lime saturator decreases. By adding a Partial flow, the amount of which is inversely proportional to that coming from the lime saturator the pump is supplied with sufficient water and a clear lime solution at the same time achieved.

In der Abbildung ist eine gemäß der Erfindung eingerichtete Wasserenthärtungsanlage dargestellt. Von dem Rohwasser, das durch die Rohrleitung i in den Reaktor 2 strömt, wird mit Hilfe einer Zweigleitung 3 ein Teilstrom entnommen. Dieser Teilstrom fließt in den Ausgleichbehälter 4, dessen Wasserspiegel durch ein schwimmergesteuertes Ventil 5 auf gleicher Höhe gehalten wird. Mit Hilfe einer Drosselscheibe 6 in der Leitung i wird unter Zwischenschaltung eines Servomotors 7 und eines Überlaufreglers 8 ein dem Hauptstrom proportionaler Teilstrom des Rohwassers aus dem Behälter 4 durch Rohrleitung 9 in den.Kalksättiger io geleitet, aus dem die Kalklösung durch den Stutzen i i in das Ausgleichgefäß 12 und aus diesem durch Rohrleitung 13 zur Kreiselpumpe 14 fließt, welche sie durch Rohrleitung 15 in den Reaktor 2 drückt, dem durch Rohrleitung i auch der Hauptstrom des Rohwassers zugeleitet wird. Das gereinigte Wasser verläßt ihn durch Rohrleitung 16.In the figure is a water softening system set up according to the invention shown. From the raw water that flows through the pipe i into the reactor 2, a partial flow is withdrawn with the aid of a branch line 3. This partial stream flows into the expansion tank 4, the water level of which is controlled by a float Valve 5 is held at the same height. With the help of a throttle disc 6 in the Line i is connected with the interposition of a servo motor 7 and an overflow regulator 8 a partial flow of the raw water from the container 4 proportional to the main flow passed through pipe 9 in den.Klksättiger io, from which the lime solution through the nozzle i i into the expansion tank 12 and from this through pipeline 13 to Centrifugal pump 14 flows, which it presses through pipe 15 into reactor 2, to which the main flow of the raw water is also fed through pipeline i. That purified water leaves it through pipe 16.

Die Rohwasserleitung i ist ferner durch eine Abzweigleitung 21 an ein Ventil 17 angeschlossen, das von einem Schwimmer 18 in dem Kalksättiger io gesteuert wird. Wenn durch die Rohrleitung 18 weniger gereinigtes Wasser entnommen wird, so sinkt auch die Menge des durch Rohrleitung i fließenden und entsprechend die durch Rohrleitung 9 zugeteilte Rohwassermenge. Daher saugt die Pumpe 14 mehr Wasser ab als zugeführt wird, und der Wasserspiegel in dem Behälter io und 12 sinkt. Auf diesen Impuls hin öffnet der Schwimmer 18 das Ventil 17 und setzt so viel Wasser zu, daß sich wieder ein gleichbleibender Wasserspiegel einstellt.The raw water line i is also connected by a branch line 21 a valve 17 is connected, which is controlled by a float 18 in the lime saturator io will. If less purified water is withdrawn through the pipeline 18, so the amount of the flowing through pipe i and correspondingly the amount flowing through it also decreases Pipeline 9 allocated amount of raw water. Therefore, the pump 14 sucks more water than is supplied, and the water level in the container io and 12 drops. On this Impulse towards the float 18 opens the valve 17 and adds so much water that the water level remains constant again.

Wird die durch Rohrleitung 16 entkommende Reinwassermenge sehr klein oder gar null, so öffnet sich das Sicherheitsventil i9 in der Umlaufleitung 20 der Pumpe 14 und verhindert dadurch Heißlaufen der Pumpe.The amount of pure water escaping through pipe 16 becomes very small or even zero, the safety valve i9 opens in the circulation line 20 of the Pump 14 and thereby prevents the pump from overheating.
