Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram of the pretreatment unit of the utility model cold rolling wastewater on-line measurement sampling.
Embodiment
As shown in Figure 1, the pretreatment unit of the utility model cold rolling wastewater on-line measurement sampling comprises cold rolling wastewater end pipeline 1, drainage pipeline 3 and sampling conduit 2, described sampling conduit 2 is communicated with described cold rolling wastewater end pipeline 1, this device also comprises UV sterilizer 4, the first valve 5, pneumatic pump 6, suction pump 7, the second valve 8, solenoid valve 9, bucket the 11 and the 3rd valve 10 keeps sample, described UV sterilizer 4 is located at described sampling conduit 2 leading portions, described the first valve 5, pneumatic pump 6, suction pump 7 is connected in series successively and the first valve 5 connects described sampling conduit 2, described suction pump 7 output terminals connect respectively described the second valve 8, solenoid valve 9, the 3rd valve 10 input ends, described the second valve 10 output terminals are communicated with described drainage pipeline 3, bucket 11 keeps sample described in described solenoid valve 9 output terminals connect, the described overflow vent that keeps sample bucket 11 connects described drainage pipeline 3, the output terminal of described the 3rd valve 10 connects the automatic monitor 12 of cold rolling wastewater.
Further, this device also comprises the 4th valve 13 and the 5th valve 14, and described the 4th valve 13 and the 5th valve 14 are located at respectively input end and the output terminal of described suction pump 7.The maintenance of this device is convenient in the setting of the 4th valve 13 and the 5th valve 14, when pneumatic pump 6 or suction pump 7 fault, can close the 4th valve 13 and the 5th valve 14 nearby, implements repair and maintenance operation.
When cold rolling wastewater on-line measurement, first valve 5 of this device, in open mode, starts after suction pump 7, by in cold rolling wastewater suction sampling conduit 2, first cold rolling wastewater is processed through UV sterilizer 4, reduces mushroom material in cold rolling wastewater, avoids generating mud in pipeline.The first valve 5 plays the on-off action of cold rolling wastewater import, and the 3rd valve 10 mainly plays controls flow and the flow velocity that cold rolling wastewater enters the sample bucket 15 of automatic monitor 12, guarantees in sample bucket 15 that waste water does not overflow and changes water sample frequency; The second valve 8 makes cold rolling wastewater flow into drainage pipeline 3 as the bypass of water pumper 7 output terminals; When the Monitoring Data of automatic monitor 12 exceeds standard phenomenon, automatic monitor 12 is controlled solenoid valve 9 and is opened, and cold rolling wastewater enters the bucket 11 that keeps sample, and in order to manual test, uses.Although cold rolling wastewater is processed through UV sterilizer 4 in this device, reduced the generation of pipeline mud, but use, also had with the passing of time unavoidably certain mud to exist, therefore when sampling conduit 2 exists certain obstruction, open pneumatic pump 6 and make pressurized air purge sampling conduit, thereby remove mud in pipeline.
Use this device can effectively avoid growth of microorganism in cold rolling wastewater, improve automatic monitor data reliability, after superscalar data, solenoid valve reacts rapidly, automatically in 5 seconds, preserve the sewage sample that exceeds standard, and can regularly control compressed air purging sampling conduit, avoid stopping up, without dismounting pipeline in the situation that, play desilting effect, reduce maintainer's workload, improve cold rolling wastewater sampling representativeness, met cold rolling wastewater and automatically monitored requirement.
