Description

Sampler for measuring oil in water

Involved in the present invention is the sampling instrument that a kind of environmental protection department is used for monitoring the water oleaginousness.A kind of sampling instrument of exchangeable reservoir particularly.Be suitable for taking of surface water such as industrial waste water, sanitary sewage.

Oleaginousness is the important indicator that environmental administration is used to weigh the water pollution degree in the water.The mensuration of oleaginousness mainly is process at present: directly take superficial water with sampling thief or spoon, then institute must the water yield be moved in the container, take back the laboratory, through extraction, finish with steps such as oleaginousness in infrared spectrophotometry or the gravimetric determination water.Yet the oil concentration data are inaccurate in the water that draws with this method of sampling, because You proportion is little than water in general, bubble through the water column usually, get superficial water or non-superficial water is done experiment, the oil concentration data that draw, and error is very big.Next water bale-out water, in shifting the container filled with water process, the oil of bubbling through the water column is introduced into container, so also can make the result higher.Therefore the instrument or the method for adopting oil in the water used at present can not scientifically reflect whole waters oil-containing situation comprehensively.

Task of the present invention is to provide a kind of novel portable to survey the sampling instrument of oil in the water.By taking the superficial water of certain depth easily,, calculate whole water body oleaginousness or total oil drain quantity more objectively according to data such as sampling bottle sectional area, sampling depth, the catch gutter depth of water, flows.Simple to operate, sampling bottle is convenient to change, and is applicable to the sampling of the face of land, river, lake, channel water, and volume is little in light weight, is easy to carry.

Task of the present invention is finished as follows: outer tube end nut is connected with whorl of bottleneck, the pull bar that is installed in the outer tube is stretched down, be threaded with the fixed bar upper end that the bottle end liner covers; Unclamp the fastening nut on outer tube top.Move down draw-in bar then, make a bottle end liner lid put into below the water layer earlier, and the sampling bottle bottom does not contact the water surface at this moment, treat that the water surface is stable, after oil reservoir closes up, put down sampling bottle (degree of depth according to circumstances determines) again, mention draw-in bar, a bottle end liner lid is adjacent to at the bottom of the sampling bottle, screws the fastening nut of outer sleeve upper, draw-in bar can not be moved.Propose sampling bottle, screw on a bottle bottom, unclamp fastening nut and draw-in bar nut, take off outer tube, cover tight bottleneck tegillum, this moment, sampling bottle just held the superficial water of certain depth under the sampling bottle cross section, two marking lines are arranged on the sampling bottle, can directly read the water intaking degree of depth and milliliter number.Sampling next time is as long as take a sampling bottle according to last method operation again.After sample has been adopted, on sampling bottle, stick label, write down date and water in bottle height and place; Take back the laboratory.In the laboratory with sampling bottle directly as operation bottle, add reagent, with the oscillator extraction, change in the separating funnel, standing demix is measured with photometry or gravimetric method.Result of calculation is the oleaginousness in the water that holds in the sampling bottle, be the oleaginousness of superficial water (equaling the water in bottle height) under the sampling bottle sectional area of certain depth, it approximates the oleaginousness of whole water layer under the sampling bottle sectional area (being a hypothesis right cylinder), emulsicool amount below the top layer is few, ignore, divided by the volume of this cylindrical water body, just draw the oil concentration of this cylindrical water body again, with the oil concentration of this concentration as whole water body.Because oil is floating on the water surface, irregular distribution, institute thinks that to make data more how objective, can in a period of time with ground a bit adopt several water samples more, result of calculation is averaged.

Characteristics of the present invention are exactly just to use conveniently, and the sampling bottle that is easy to carry loads and unloads easily, and sampling bottle still is the laboratory operation bottle simultaneously.

Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.

Figure one is a kind of concrete structure of the present invention

Figure two is the outer tubes among the present invention

Figure three is the draw-in bars among the present invention

With reference to figure one: sampling bottle [1] is one and has two marking lines (centimetre, milliliter), last bottleneck [9] has externally threaded no-bottom bottle, the no-bottom bottle lower edge has the sulculus [12] of putting into packing washer, there is external thread [10] the lower edge outside, owing to need read the water intaking degree of depth and milliliter number after sampling finishes, so sampling bottle will be cast with organic glass or transparent rigid plastic.Bottleneck lid [2] is a vinyl cover.The effect of bottle bottom [3] is with bottleneck lid [2], just because stressed bigger during as the operation bottle in the laboratory, needs make with metal, and internal thread is arranged.On the bottle end liner lid [4] fixed bar [11] is arranged, draw-in bar [8] be exactly with fixed bar [11] on connect, bottleneck [9] has external thread, with sampling bottle [1] be an integral body.

With reference to figure two: outer tube [5] is made by rigid plastic or steel or casting property nylon aluminum alloy materials, and its effect is stable, the lifting of doing handle and control bottle.There is taper-thread [13] upper end, and fastening nut [6] overlaps thereon.Lower end [7] is for having the nut of spilehole.Outer tube [5] is connected in aggregates with nut [7].The inwall of outer tube [5] and draw-in bar [8] are the activity mated condition, or be respectively charged into the stationary pipes that is the activity mated condition with draw-in bar [8] on the inwall at two ends up and down at outer tube [5], its objective is in order to prevent that draw-in bar [8] from rocking in outer tube, a bottle end liner lid [4] is unlikely occurs tilting, and the phenomenon that can't seal sampling bottle [1].Outer tube [5] is made and can be connected the lengthening formula.
