Embodiment
Now, describe embodiment of the present utility model in detail in conjunction with Figure of description:
As shown be branch sampling instruments such as straight fraction sewage, by last shelf 11, following shelf 17 space segmentation is become three zones, upper, middle and lower in the rack 18, rack 18 top area install be provided with microcomputerized controller 9 and with peristaltic pump 8, the GPRS module 10 of its circuit control linkage, GPRS module 10 is used for receiving remote control center sampled signal.The central region of rack is installed pretreatment unit 6, low temperature chamber 13, water storage bottle 12 and relay control interface 5 is set.Pretreatment unit 6 is used for the gas of draining-off sewage, separate the solid waste in the sewage, guarantee to gather the quality of water sample, entrance point is connected with water inlet pipe 1 through water intaking valve 4, be equipped with suction pump 2 on the water inlet pipe 1 place connecting line, suction pump 2 places the lower region of rack 18; The connection of pretreatment unit 6 bottoms is provided with drainpipe 20, is equipped with outlet valve 3 on the drainpipe 20; Be equipped with the level switch 7 with microcomputerized controller 9 circuit control linkages in the pretreatment unit 6, with the pre-service run-down pipe 21 that is connected with drainpipe 20 pipelines; Pretreatment unit 6 endpiece are connected with water storage bottle 12 through peristaltic pump 8, and peristaltic pump 8 is set the working time of peristaltic pump 8 and determined sampling quantity by the constant rotating speed extraction constant flow rate or the water sample of flow.The import that water storage bottle 12 is connected with peristaltic pump 8 is arranged on bottle top, and is lower than this entrance location on bottle top and is equipped with the water storage run-down pipe 19 that is connected with drainpipe 20, is used for water storage bottle 12 unnecessary water are discharged; Water storage bottle 12 bottoms are connected with sampling valve 14, three-way pipe 15 in placing low temperature chamber 13, and the suitable for reading of three-way pipe 15 is import, is connected with water storage bottle 12 pipelines; The diameter of 15 liang of end openings of three-way pipe is identical as delivery outlet, two isometrical delivery outlets respectively with place low temperature chamber 13 in sampling bottle 16,16a pipeline be connected; The position of water storage bottle 12 is higher than sampling valve 14, three-way pipe 15 and sampling bottle 16,16a, effect by gravity, the water of water storage bottle 12 from top to bottom enters two sampling bottles 16,16a through sampling valve 14, three-way pipe 15 five equilibriums, and sampling valve 14, three-way pipe 15 and two sampling bottles 16,16a place in the low temperature chamber 13 and can keep gathering the sewage sample not because of the deterioration failure of temperature height.Described water intaking valve 4, sampling valve 14, outlet valve 3 all adopt motorized valve, and water intaking valve 4, sampling valve 14, outlet valve 3, suction pump 2, peristaltic pump 8 are respectively by relay control interface 5 and microcomputerized controller 9 circuit control linkages.Described level switch 7 is a signal triggering device, if still indicate lack of water through one section time of pumping process level switch 7, the expression flow is too small, and this moment, sampling instrument was not sampled, to avoid unreliable sampled result; If be triggered at this section period level switch 7, microcomputerized controller 9 control suction pumps 2 stop, water intaking valve 4 is closed, and the expression sewage sample of waiting to sample is ready to, start peristaltic pump 8, sampling valve 14 is sampled; Before sampling action was finished, outlet valve 3 was closed always, opened outlet valve 3 after each sampling finishes and bled off sewage.
When beginning to sample, peristaltic pump 8 counter-rotating is finished the automatic cleaning to pipeline remaining between peristaltic pump 8 and the water storage bottle 12 the sewage back suction on the connecting line last time to pretreatment unit 6 the insides.Open water intaking valve 4 then, start suction pump 2 and advance the sewage sample in pretreatment unit 6, unnecessary overflowing from pre-service run-down pipe 21 enters drainpipe 20.When not reaching enough liquid level in the pretreatment unit 6, level switch 7 can not be triggered, and samples with regard to not starting peristaltic pump 8, and suction pump 2 and water intaking valve 4 continue open-minded.Reach set liquid level, sewage sample and fully mix after, water intaking valve 4 is closed, suction pump 2 quits work.Starting peristaltic pump 8 is just changeing, and extracts the sewage sample in pretreatment unit 6.The water sample that peristaltic pump 8 extracts is stored in the water storage bottle 12, opens sampling valve 14, and the water of the effect water storage bottle 12 by gravity from top to bottom flows into through sampling valve 14, three-way pipe 15 five equilibriums and enters two sampling bottles 16,16a.Sampling is finished, and closes sampling valve 14, opens outlet valve 3, the sewage in the pretreatment unit 6 is bled off, and peristaltic pump 8 counter-rotatings, sampling is next time prepared in detergent line once more.
