The purpose of the utility model realizes through following technical scheme:
Semi-volatile organic matter is the water sample sampling apparatus substantially, it is characterized in that, comprising:
A kind of cardinal principle water sample sampling apparatus comprises:
Suction pump is used for extracting water sample through the drinking-water pipe that is arranged on the suction pump, and said water sample is transported on the filter plant;
Filter plant be used for the water sample that suction pump extracts is filtered, and the water sample after will filtering is transported on the adsorption plant;
Adsorption plant is used for adsorbing the dissolved colloidal state particle of said water sample;
Flowmeter is used to measure the volume of water sampling;
The circuit opertaing device that draws water is used for the start and stop according to the measure control suction pump of flowmeter.
The semi-volatile organic matter that the utility model provides water sample sampling apparatus substantially has compact conformation, simple, convenient characteristics of carrying; Can once accomplish filtration, absorption, the sampling volume calculating of water sample in sampling process; Provide convenience for big water by volume appearance in-situ enrichment, can be used for the original position sampling of all kinds of water body water samples such as shallow lake, river, reservoir.
Description of drawings
Fig. 1 is the structural representation of the cardinal principle water sample sampling apparatus that provides of the utility model embodiment.
Embodiment
The utility model embodiment provides a kind of cardinal principle water sample sampling apparatus, and is as shown in Figure 1, comprising:
Suction pump 1 is used for extracting water sample through the drinking-water pipe that is arranged on the suction pump 1, and said water sample is transported on the filter plant 2;
Filter plant 2 is used for the water sample that suction pump 1 extracts is filtered, and the water sample after will filtering is transported on the adsorption plant 3;
Adsorption plant 6 is used for adsorbing the dissolved colloidal state particle of said water sample;
Flowmeter 7 is used to measure the volume of water sampling;
The circuit opertaing device 8 that draws water is used for the start and stop according to the measure control suction pump 1 of flowmeter 7.
Concrete, the power supply of suction pump 1 can adopt 220V alternating current or accumulator to drive, and the water withdrawal of suction pump 1 is 10ml-5000ml/min.Clip 4 lockings are used in the top of filter plant 2 and intake-outlet junction, bottom, and the bottom of filter plant 2 is provided with three to four support columns 3, and filter plant 2 can use filter membrane material, and its aperture is 0.4-3 μ m.On filter plant 2, can also be provided with controlled pressure valve 5; Be used to regulate the air pressure balance in the filter plant; Concrete, when the water sample after beginning to sample is full of filter membrane pallet 2, regulate the air pressure balance in the filter membrane pallet 2; Can be covered with filter membrane uniformly to keep water sample, and the water sample flow velocity of guaranteeing the quality is steady.Adsorption plant 6 is processed column by stainless steel or glass material, and the two ends of adsorption plant 6 connect the sampling pipe interface and use reversal of the natural order of things thorn shape.The circuit opertaing device 8 that draws water can adopt the start and stop of FPGA according to the measure control suction pump 1 of flowmeter.
The principle of work and the method for operating of this embodiment are following:
The cardinal principle water sample sampling apparatus that this embodiment provides according to above-mentioned assembling after, at first sampling pipe is put into water body, and the volume that needs sampling, the parameters such as operating rate of suction pump 1 is set in the circuit opertaing device 8 that draws water.Before formal energized sampling, use entanglement to surround sample water pipe place, block pipeline to prevent that the bulky grain thing from getting into.After the preparatory stage completion; The power supply of connecting suction pump 1 begins to extract water sample; Water sample passes through sampling pipe earlier through the membrane filtration in the filter plant 2, crosses sorbing material, process flowmeter 7 discharges at last in the adsorption plant 6 then, complete system of whole composition.
