Measuring vessel for continuous quality control

of water

The innovation concerns a Heßgefäß for continuous quality control of water, especially for measuring the oxygen _; content, pH value, conductivity, temperature etc. of waste water.

In today's water management it is necessary to check the quality of the water before the. Use to be constantly monitored before, during and after cleaning. This is done primarily in order to counter any changes in quality as quickly as possible with the appropriate means and to protect the consumer from damage and, in particular, the sewage treatment plant from a. ^1st To be able to keep work in unfavorable areas. ;

To monitor the quality of water, the most diverse Ι ·; θ3εοηάε-Γ- and feelers are used. One grasps these devices in general; common in a measuring vessel, through which one of the to be examined Water flow branched off partial flow is passed.

'ill; .. to obtain reliable measured values, a regular ¹ ... ng of the device is required in a very short time In practice, however, it is not feasible, especially: not for systems that are set up, for example, to monitor river water.

It was therefore the task of largely avoiding this contamination of the Heßgefäßes and, while reducing the maintenance effort, reliable 1 ·>;ί3ν.'υ- ·., Ο zv · This task is achieved according to the present firing by the fact that the vessel di <; Has the form of a hydro ^ / kioris and the inlets and outlets are arranged on it, that a rotating about the longitudinal axis of the vessel Zyklonströ- \ mung is formed in which the probes are located. As a result of these measures, a central flow is generated in the measuring vessel, which flows around the measuring probes protruding into this flow at high speed. Due to this high flow rate, the protective substances have no way of settling on the measuring devices. Rather, they are washed out again with the flow of water. In order to generate the vortex flow, the inlet expediently opens laterally and el · .. ·· tangentially into the vessel. The drain is then approximately in the center of the cover, so that the water covers a long spiral path, on which it flows intensively around the measuring probes. According to a further embodiment, a second outlet can be provided in the bottom of the vessel, which preferably has a variable flow cross-section. The inflowing water then divides into two partial flows, of which the one directed towards the floor drain primarily takes the suspended matter with it, which is then led out of the vessel again as quickly as possible. The variable lower drainage amount also allows the amount overflowing to be adjusted so that one always has a check on whether the liquid flow is flowing properly or whether it is interrupted. |

The lid is preferably provided with a raised edge on the outside, which has an overflow opening at such a height that the Lid is always covered with a layer of water. That makes it easier the control and at the same time ensures that the measuring vessel is always filled with water. Ur ;: to continue to negate that with under-

Depending on the volume of the outlet opening, this scrambled ice cream and the inflow, an up or down spiral flow may appear in the vessel. If the turbulence is aun: Keeping the measuring points free is not yet sufficient, they can be reinforced with the help of a stirrer. In this case vorzu forms ^ sv.'eise the central Abiaufrohx ¹ eic this hollow shaft agitator which projects through dt .1 lid from above into uac vessel; this shaft is connected to a drive which has a Rührerströr.ur.n; generated, which run in the same sense as the rotational flow given by the tangential inflow. In the section of the hollow shaft lying between the cover and the drive motor ¹ , the hollow shaft is provided with openings through which the water flowing out of the vessel can escape the incoming water leaves both processes to approximately the same extent.

An exemplary embodiment of the innovation can be seen from the accompanying drawing; it is briefly explained below:

The measuring vessel I has a cylindrical upper part 2 and a truncated cone-shaped bottom 5 which expires in an outlet line k. The line 4 can be closed by a valve 5; its flow cross-section can be changed by means of an adjustable throttle "j> 0 .

At the top, the vessel 1 is closed by a removable cover 6 which rests loosely on cams 26. In the edge 7 protruding above, an overflow pipe 8 is arranged, in which a sensor 9 is located. This sensor viird from overflowing water actuated and opens in operating position over ax S-stop line Q <^ ^as magnetically operated bottom valve 5 · Remains of the overflow, then nothing can leak by the Bodenabiauf.

The lid also includes a central outlet bore 14 through which the Welie Ii; a stirrer rs io in aas Ce barrel ra ^ .. The V / elle I5 is driven by a geared motor Io, which has a Lantern I9 is supported on the cover υ.

In its cylindrical part 2, the measuring base i also has a tangential av; s, jcrichtc inlet valve.3 20.

On the side of the. Lid ό attached and connected to it by a recess 17 communicating with it is a pocket 2 ^l j in which a float switch 27 is arranged. It is used to give a stop pulse when the water level 24 in the cover ό rises above a permissible level, which can be caused, for example, by clogging of the overflow 8. In order to ensure that the cover 6 is inserted in the correct position, it is provided with a notch at one point on the uni-catch, which engages over an ila.se 2b located on the edge of the housing.

When the measuring device i is started up, the V / asscr runs in the direction of the arrow ? .'- j through the tangential inlet pipe 20 to the measuring vessel 1. The water flow then divides into two toilet flows. The upward part uirispülo in For-j ;; an ascending Viirbelstrom 22 the measuring probes 11,12 and emerges from α ahn through the zontraie opening in the cover upwards. A liquid level 24 predetermined by the overflow 8 is maintained. The descending part 29 of the viasser inlet stream f licit, ur.d, although also in the form of a spiral vortex, to the lower outlet 4. Due to the cyclic action of this flow, it takes with it the major part of the sinkable water constituents, the sc:. '. It, in the shortest way and without coming into contact with the measuring probes Measuring vessel are conveyed out again. Suspenders, the

not ir.it pulled downwards, get into the center of the upward vertebral wheel get through early the central opening 14 to the outside, so that they too become dirty the heating probes do not contribute to körinen.

The throttle ^ O is usually set so that half of the Inlet below, the other half emerges from the top of the vessel. This is on the one hand for a sufficient rinsing of the Keßsonden and on the other hand for a controlled extraction of the Sinkatoffe taken care of, so that a cleaning of the vessel only in a great deal large time intervals is necessary.

Numerous other configurations of the heating device are conceivable. For example, 3. other types of stirrers to produce the spiral grooves be used; the cover can when the drain through the hollow shaft of the stirrer takes place, a special one that can be closed by a valve Have opening, which when starting up the measuring vessel is opened so that the air can escape upwards, as the gap between the lid and the vessel may not be able to do this sufficient.

A pump can be used to supply the water to be examined will; the free inlet as a result of a hydrostatic gradient is also conceivable. It is easily possible during operation Briefly remove individual measuring probes with their stoppers from the cover for checking or cleaning. Because the water level is constantly held through these openings, no air can penetrate into the vessel in this way.
