Abstract
The utility model provides a hollow which can stably and reliably detecting water dissolved oxygen in the sealed water sampling and reaction apparatus for water analysis, composed of a sampling reaction bottle 1, an agent adding tube 2, a magnetic stirrer 3, and a standard color bottle. The sampling reaction bottle and the standard color bottle are all glass bottles with good light transmission performance. The agent adding tube is a glass tube with volume scale, and the lower end of the agent adding tube is provided with a screw plug; the periphery under the screw plug is a grinding mouth which is in sealed match with a grinding mouth of the sampling reaction bottle to prevent air from entering, with assurance of stable and reliable analysis result. A water sample sampling reactor can be fixedly arranged on a sampling mouth of a water system and can be continuously used.
Description
The utility model proposes a kind of water analysis with the water sample reactor of taking a sample.
Prior art, in order accurately to measure the content of oxygen in water, sampling method is one of key.The standard GB 1576-85 of China and the books and reference materials of relevant DO determination, and all sampling jar is put into sample bucket in the existing working specification of factory, belong to worn-out open type, only under the situation that we opens, take a sample, required reagent inserts in the bottle with common buret and adds, certainly will in operating process, can dissolve in the water sample again by airborne oxygen like this, also be difficult to grasp thereby make measurement result be difficult for stable and operate.
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of water sample sampling reactor of closed, and it can avoid water sample to contact with air effectively, makes measurement result reliable and stable, and is easy and simple to handle.
Technical solution of the present utility model: by sampling reaction bulb 1, reagent adds pipe 2, magnetic stirring apparatus 3 and standard color range bottle and forms, sampling reaction bulb 1 is wherein put on magnetic stirring apparatus 3, and it is to insert in the dropping reagent mouth of sampling reaction bulb 1 that reagent adds pipe 2.
Sampling reaction bulb 1 has a water sample induction pipe a, and its end face has ground b in the spill, and there is an overflow vent c its side;
At the bottom of the sampling reaction bulb bottle is surface level, and the bottle top is a side height, and the inclined-plane that a side is low connects and the corner is the angle, garden;
Reagent adds the uniform glass tube of pipe 2 usefulness internal diameters to be made, and is carved with the volume scale more than the cock, and the following periphery of cock is the ground that is complementary with the sampling reaction bulb;
Standard color range bottle is all identical with size, shape, the material of sampling reaction bulb, and the bottle end face can only stay a bottleneck, adds grinding port plug;
The water sample induction pipe a of sampling reaction bulb 1 is a penstock, and it pushes up a side from bottle and inserts the bottle end, and conduit fuses into one with bottle.
The sampling reaction bulb of the utility model design is that a light transmission is good, the vial that volume is suitable, the import of bottle is connected with water system with common threeway, outlet feeds wastewater disposal basin, end face leaves and drips the reagent mouth, contact with air for fear of water sample, reagent adds pipe and adopts ground to cooperate with the dropping reagent mouth of sampling jar, is coated with paraffin wax after installing again and seals.Reagent adds pipe from reagent and is added drop-wise to as required the sampling jar, finishes chemical reaction under magnetic stirrer, obtains analysis result with standard color range colorimetric again.
Advantage of the present utility model:
Owing to all avoided water sample to contact with air in the whole process of sampling and chemical reaction, institute is so that measurement result is accurate, stable, reliable.Especially more remarkable to boiler with the mensuration of trace oxygen in the deaerated water; Because the reagent pipe is fixed on the sampling jar, make simple to operation again; Also since whole device be fixed on the sample tap of water system, therefore can be at any time the situation of change of on-line monitoring water oxygen continuously.
Accompanying drawing 1 is an example structure synoptic diagram of the present utility model.
Accompanying drawing 2,3,4 is respectively the structural representation of sampling reaction bulb 1, visual colorimetric determination standard color range bottle 3, reagent adding pipe 2.Among the figure 4 is that sample introduction switch, d are magnetic stir bars.
Below in conjunction with accompanying drawing technical solution of the present utility model is further described:
Water sample sampling reactor is added four parts such as pipe 2, magnetic stirring apparatus 3 and visual colorimetric determination standard color range bottle and is formed by sampling reaction bulb 1, reagent.A among Fig. 2 is the water sample induction pipe, and b is a ground in the spill, and c is the water sample overflow vent.At the bottom of requiring a pipe to fuse into one and being deep into bottle with bottle; The ground of ground and reagent adding pipe is complementary in the spill; C is an overflow vent, its height should with the sampling reaction bulb end face on same surface level.The end of sampling reaction bulb is a surface level, and the bottle top is the low inclined-plane of the high side of a side, and the bottle internal volume is 280ml or other suitable volume.Standard color range bottle, its size, shape are identical with the sampling reaction bulb, but can not open injection port and overflow vent, and end face also can be a level, and the ground place should add a frosted bottle stopper.Glass blowing all good with light transmission, that wall thickness is even, interior external diameter is identical forms the sampling reaction bulb with standard color range bottle.Connection and corner are the angle, garden, and the ground of sampling reaction bulb concaves down, and the ground of standard color range bottle also can raise up.
