Description
Technical field:
The utility model relates to that open channel is measured, duct type measuring technique and sewage Sampling techniques, particularly a kind ofly mainly is used in the Sewage metering sampling instrument that sewage (waste water) discharge sites is carried out real-time sampling and Sewage metering.
Background technology:
Existing sewage sampling instrument all is sampling function and the constant temperature function of finishing sewage singlely, and the principle of taking all is the peristaltic pump principle, and sewage suction pipe cracky, sampling quantity are difficult to control.Simultaneously, also mainly be to the sampling of the sewage in the open channel, and the more important thing is that they all do not have the Sewage metering function.
Summary of the invention:
Goal of the invention of the present utility model provides a kind of Sewage metering sampling instrument that Sewage metering function and sewage sampling function is organically combined, adopts the vacuum pump sampling.
The technical scheme that realizes this goal of the invention is: this Sewage metering sampling instrument is by the sensor that is arranged on sewage detection point, being installed in parts such as interior controller of constant temperature oven and sampling thief forms, this controller mainboard is built-in with automatic gauge display circuit and controlling of sampling circuit, this automatic gauge display circuit is connected with sensor electrical, the signal output part of this controlling of sampling circuit is electrically connected with the vacuum pump starting switch of sampling thief and the signal input part of electromagnetic valve group respectively, this vacuum pump is communicated with the Measuring glass gas circuit by this electromagnetic valve group, this Measuring glass is communicated with source of sewage and sampling bottle respectively by sewage suction pipe and sewage distributing pipe, on this sewage distribution circuit electromagnetic valve is housed.The sampling of sewage by vacuum pump by vacuumize form malleation and negative pressure after, switching solenoid valve is finished the sewage sampling process one time, then the sewage in the Measuring glass is redistributed in each sampling bottle; In sampling, finish the calculation of total of sewage discharge, also can demonstrate the instantaneous flow of sewage discharge simultaneously; The main effect of constant temperature oven is to guarantee that institute's sample liquid is stored under the environment of ideal temperature.
According to the Sewage metering sampling instrument that this technical scheme realizes, can be widely used in the metering sampling work of the industrial waste water of industries such as oil, chemical industry, papermaking, printing and dyeing, building materials, electric power, metallurgy, municipal administration.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a controller circuit structure synoptic diagram of the present utility model.
Embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.The described Sewage metering sampling instrument of this embodiment is made up of sensor 1, controller 2, constant temperature oven 3, vacuum pump 4, electromagnetic valve group 5, Measuring glass 6, electromagnetic valve 7, sewage distribution circuit 8, sampling bottle 9, level probe 10, sewage suction pipe 11, these controller 2 mainboards are built-in with automatic gauge display circuit and controlling of sampling circuit, this its signal input part of automatic gauge display circuit is electrically connected with sensor 1 by 12 A/D converters, and this sensor 1 is a ultrasound wave open channel sensor.Its signal output part of controlling of sampling circuit of these controller 2 mainboards is electrically connected with vacuum pump 4 driving circuits and electromagnetic valve group 5 driving circuits respectively.This vacuum pump 4 is communicated with Measuring glass 6 gas circuits by this electromagnetic valve group 5, this Measuring glass 6 is communicated with source of sewage 12 and sampling bottle 9 respectively by sewage suction pipe 11 and sewage distributing pipe 8, on this sewage distribution circuit 8 electromagnetic valve 7 is housed, be provided with level probe 10 in the Measuring glass 6, these level probe 10 signal input circuits are electrically connected with the respective input mouth of controller 2 mainboards.
The utility model is a kind of Sewage metering sampling instrument that integrates built-in ultrasonic open channel flowmeter, vacuum pump sampling system, constant temperature oven three parts and controlled by microprocessor, utilizes metering system to finish equal proportion sampling by flow, time.
Its course of work: function of measuring is provided with sampling pattern → vacuum pump work → purging → imbibition → quantitative → plurality of processes such as discharge opeing → constant temperature simultaneously.
Sampling process: vacuum pump 4 energising work, close electromagnetic valve 7, vacuum pump 4 blows off in the sewage suction pipe 11 behind the raffinates (malleation), electromagnetic valve group 5 commutations, Measuring glass 6 is in negative pressure state liquid to begin to suck, when liquid reaches predetermined fluid level, and 10 conductings of metal liquid level probe, electromagnetic valve group 5 begins commutation, become barotropic state in the Measuring glass 6, liquid begins to be discharged to source of sewage 12 by sewage suction pipe 11, and discharge opeing stops when liquid level reaches quantitative position, vacuum pump 4 quits work, and promptly quantitatively finishes.Electromagnetic valve 7 is opened then, and the liquid sample in the Measuring glass 6 is discharged in the sampling bottle 9, adopts to such an extent that the liquid sample is deposited and constant temperature is preserved in the constant temperature oven 3, guarantees the temperature constant state of sample, so far finishes a sampling process.
