Description
Technical field
The utility model belongs to stirring reaction technical field, relates to the stirring apparatus in a kind of automatic sampler particularly.
Background technology
Water sample automatic sampler is the multifunctional monitoring instrument of collection flow measurement and water sampling integration, be applicable to environmental monitoring station at different levels, sewage treatment plant, water conservancy, water utilities and scientific research institutions, the water samples such as industrial pollution source floss hole, river, river, lake, sea are sampled automatically.Auto injection and hybrid reaction process accurately control the sample introduction ratio of sample and reagent while realizing robotization, guarantee the reliability of measurement result, repeatability and stability.
Automatic sampling apparatus of the prior art instead of manual sample introduction and varies, and improves automaticity and the analysis precision of lab analysis work.But, in actual water analysis work, after sample to be determined containing materials such as solid particles has been placed of a specified duration, often there is solid-liquid two phase stratification phenomenon, when the sampling needle of automatic sampling apparatus draws this sample to be determined, sampling will be uneven, sample representativeness will be caused to be deteriorated, and then affect sample detection analysis precision.
Summary of the invention
The utility model is exactly uneven and affect the problem of sample detection analysis precision in order to solve above-mentioned sample to be determined, provides the stirring apparatus in the simple automatic sampler of a kind of structure.
For achieving the above object, the utility model adopts following technical scheme.
The utility model comprises stirring cylindrical shell, the first aerating device, the second aerating device, and described stirring cylindrical shell is provided with cover; Its structural feature is: described cover is provided with drive motor; Described stirring cylindrical shell internal upper part is provided with the first shaft, first shaft is connected with drive motor by driving shaft, described first shaft is provided with paddle and goes out vent hole with several, the upper end of the first shaft is connected with the first aerating device by connecting pipe; In described stirring cylindrical shell, bottom is provided with the second shaft, the external side of described churn is provided with the second aerating device, outer lower portion is provided with out liquid interface, described second shaft one end is connected with the second aerating device, described second shaft is provided with several and goes out vent hole; Described first shaft and the second shaft are hollow structure.
As a kind of preferred version of the present utility model, described first aerating device, the second aerating device are all provided with flowrate control valve.
As another kind of preferred version of the present utility model, described first aerating device, the second aerating device adopt compressor or air pump.
The beneficial effects of the utility model.
Cover described in the utility model is provided with drive motor, also comprise the first shaft and paddle, the second shaft, first aerating device, the second aerating device and flowrate control valve, its structure is simple, control is convenient, can On-line Control be realized, further increase automaticity and the analysis precision of analytical work.And the utility model stirring apparatus can support the use with multiple analytical instrument, product is widely applicable; Sample liquid is sampled evenly, the uneven suspension water body that the range of application of automatic sampler extends to particle from homogeneous sample analysis can be measured, expand the scope of application of product; The volatility interfering material in testing sample can be removed, make analysis result more accurate.If when follow-up sample determination, volatile matter has interference, can reach removal object by extending air blowing mixing time.As, during Gas-phase Molecular Absorption Spectrometry sulfide, volatile organic matter interference is very serious, and applying this product then can be clean by there being interference volatile organic matter to purge.
