Be the one in fig. 1 and 2, the container 1 is made up of a shell 2 and a base 3 , which is formed here by a flat disk. An overflow pipe 4 is fastened almost concentrically to the shell or side wall 2 on the flat disk 3. hen. Rings around the overflow pipe 4 extends a. Baffle plate 6, which - as in particular from Pig. 1 sees «borrowed - runs helically. The front edge 7 of the baffle plate is above the ^! anal liquid level, and the rear edge 8 below the minimum liquid level. At the point of the front edge 7, the baffle plate 6 extends over the entire area between the overflow pipe 4 and 4-sided side wall 2, but after a certain distance it strikes an edge from the side wall 2 and is from this point on a bent band 9 provided * that stretches to the rear Xante 8 ere »The rear edge 8 ends some distance behind the long SBOhlitE 5 of the overflow pipe 4. At the top of the baffle plate 6, directly behind the chute 5, a plate 10 is attached which extends between the overflow pipe 4 and the side wall 2 of the container and ends above the naxiaalen fluid level.

At the bottom of the container a nozzle 11 is somewhat tangential aligned, from which liquid in the Container flows in such that this liquid

As a result of the continuous supply of fluids runs the flow along a helix with an upward slope. Bas su mingling Material is swiecken the belts 7 and 8 of the Baffle plate 6, that is to say positioned in front of the edge 7 in the direction of flow, is controlled by the flow of liquid taken away and provided it is not bit by then the liquid is mixed against the baffle plate 6 pressed where it merges with the liquid one downward velocity component is given, causing an intimate mixing with that from below hoohstrumenden fluid takes place.

The nozzle 11 is by means of a tube 12 into which a Valve 13 is inserted, connected to the feed line 14 of a pump 15, as shown in the above. Representation of Fig. 3 can be seen.

A water jet pump 16 is located in the feed line 14 Arranged behind the branch pipe 12, the piping pump is with an opening 17 in the bottom 5 of the container 1 connected within the area of the upper reaches rohree 4. The water jet pump 16 thus sucks the generally container 1 treated liquid in the direction of arrow Q.

formed in pieces and below the bottom 5 of the Container 1 arranged. That way is a very compact structure achieved. In most cases it can Plastic material can be used, which means that the device can be built very cheaply.

To keep the fluid level at the desired height to be held so that it lies between the edges 7 and 8 of the baffle plate is between the feed line 14 and the container 1, a branch pipe 18 is arranged. In this branch pipe 18 there is a hand P regulated shut-off valve 19 and a solenoid valve 20 arranged, which is controlled by means of a device 21 for monitoring the liquid level 1st, which in the Overflow tube 4 is arranged. The device 21 for Monitoring of the liquid level is through a Protected pipe 22, which is fixed in the overflow pipe 4 and is in open communication with this pipe at its upper and lower ends. This becomes the monitoring device 21 iron does not act directly on the liquid t through the longitudinal slot 5 in the overflow pipe 4 enters

How understandable should be »the facility works 21 to monitor the liquid level so that when the liquid level falls below one The slectro valve 20 is opened to a certain value, through which additional liquid is passed into the container 1 will. Bas Neitswaigrohr 18 opens close behind of the plate 10 into the container 1, so that the liquid flowing out of the tube 18 is hardly affected by the mixing process in the Container takes part, but flows almost directly into the overflow pipe 4.

Sas pipe 18 and the Valves 19 and 20 must be owned so that the liquid level then slowly rises so that after a certain time the monitoring device 21 closes the valve 20 again.
