Embodiment

Fig. 1 illustrates the container 1 of the physical-chemical parameters for measuring water sample 2 of the present utility model.Can find out, container 1 comprises the conduit 3 being suitable for the straight vertical layout that water sample 2 flows through, and is provided with three the physical-chemical parameters and measures detector 6 in conduit 3.The detector 6 used can be suitable for measuring as pH value, the known detector of the physical-chemical parameters such as turbidity.Certainly, predictably, the quantity of detector 6 can be variable, and a physical-chemical parameters detector and several the physical-chemical parameters detector can be placed in the conduit 3 of container 1.It can also be seen that, detector 6 is arranged to align in same vertical projection, and equidistant each other in the conduit 3 of container 1.

The conduit 3 of container 1 is provided with the lower inlet 4 for water sample 2 and the upper outlet 5 for water sample 2, and the water that analyze is by pump 11 and be injected in conduit 3 via lower inlet 4, and the water be introduced in conduit 3 is discharged via upper outlet 5.Vertical conduit 3 allows the fetch phase shown in Fig. 1 upwards to be carried from bottom to top by shown in arrow by described water sample 2.At fetch phase, water sample 2 cycles through conduit 3 from bottom to top, because conduit 3 is straight with vertical, so conduit 3 prevents the bubble of false readings in detector 6 that can cause that can circulate together with water sample 2 to be retained.At described fetch phase, different detector reads each the physical-chemical parameters of water sample 2, and is stored by the physical-chemical parameters or be sent to unshowned control device to produce the report of the situation about water sample 2.

Although only a part of detector is inserted in the wall 7 of conduit 3 obliquely is also possible, as shown in Figure 1, all detectors 6 are inserted in the wall 7 of described conduit 3 all obliquely.But preferably, all detectors 6 are all inserted obliquely into, the conduit 3 with small cross sections can be used.

As shown in the figure, at least one in all detectors 6 or detector 6 is inserted in the wall 7 of described conduit 3, obliquely to downward-extension, that is, on the direction contrary with the throughput direction of the water sample 2 in conduit 3.Certainly, replace to downward-extension, in appropriate circumstances, as long as in order to the measurement result that obtains detector 6 and vertically the shape of conduit 3 allows, detector upwards or to extend towards other side be possible.

Detector 6 is inserted in conduit 3 obliquely, and the wall 7 of described conduit 3 forms the angle [alpha] between 15 and 45 degree, that is, be arranged in the position more vertical than level.Although advantageously all detectors are inserted into and form identical angle [alpha], but according to the type of detector 6, it is possible for being arranged in by different way in conduit 3 detector, thus it is also envisioned that only a part of detector 6 be inserted obliquely into and and the wall 7 of conduit 3 form angle [alpha] between 15 and 45 degree.Preferably, insert among the different angles α in conduit 3 at detector 6, be considered to particularly advantageous when this angle [alpha] is 30 degree, thus at least one in all detectors 6 or detector 6 is inserted obliquely into and forms the angle [alpha] of 30 degree with the wall 7 of conduit 3, and with water sample 2, there is good surface of contact when not hindering water sample 2 to circulate.

Being cleaning stage after fetch phase, cleaning stage can be performed simply by making water sample 2 circulate before carrying out the measurements, thus the bottom may staying conduit 3 being pulled away with the residue of the early stage water sample on any one detector 6.But the potpourri execution cleaning stage as shown in Figure 2 of the solution utilizing pressurized air and have germifuge is preferred, can pollute conduit 3 or detector 6 to prevent the residue of early water sample 2 and affect next fetch phase.

In this cleaning stage, the potpourri of air and germifuge is introduced in conduit 3 via the auxiliary entrance 8 of the lower end being arranged in described conduit 3, auxiliary entrance 8 is connected with germifuge injection devices 9 such as such as pumps, germifuge injection device 9 collects germifuge from germifuge vessel 10, and after germifuge mixes with air, the potpourri of pressurized air and germifuge is injected conduit 3 via auxiliary entrance 8.The potpourri of germifuge and bubble is conducive to sterilizing to conduit 3 and detector 6 and removes the residue on the wall 7 that may be attached to conduit 3 and detector 6 carried by water sample 2.Advantageously, because detector 6 to tilt and conduit 3 is vertical, so prevent the air injected together with germicidal solution to be retained on detector 6 and conduit 3.

The potpourri of air and germifuge, after being injected into by auxiliary entrance 8 and flow through conduit 3, being discharged via upper outlet 5 as indicated by the arrows of fig. 2 and is processed in cleaning stage.

Finally, before the new water sample 2 of introducing performs measuring phases again, clean water is preferably utilized to perform rinse stage, to remove the residue of the germicidal solution may keeping in conduit 3 and on detector 6.As selecting or supplementing, water sample 2 can cycle through conduit 3 a period of time, measures to guarantee that all germicidal solutions are removed and do not affect next time.

Thus achieve following ability, that is, continuous coverage in time the water sample 2 at interval the physical-chemical parameters and prevent the measurement result of the residue interference continuous print water sample 2 of water sample 2.Certainly, the measurement result of the physical-chemical parameters obtained by different detector 6 will be stored or be sent to control center, monitor water sample 2 thus and also produce report at the physical-chemical parameters in each moment or notify whether any the physical-chemical parameters exceedes alarm threshold.

In order to allow to change the detector 6 that may damage or reach end in its in serviceable life, or even in order to any one detector 6 replaced by the detector 6 that utilizes another to improve or the detector of measuring another the physical-chemical parameters interested, detector 6 is attached to the conduit 3 of container 1 removedly in the mode of leakproof, thus as shown in the detail drawing of Fig. 3, can remove detector 6 from conduit.Advantageously, because detector 6 is arranged in an inclined manner, thus they allow conduit 3 narrower, and allow for hold container 1 to be removed the space outerpace that must pass through narrower with detector 6, make detector 6 take less horizontal section this is because detector 6 inserts in the conduit 3 of container 1 obliquely.
