Abstract

The utility model discloses a double flow path anti-interference flowable sample pool comprising an internal and external pool including internal and external two pipe bodies. The double flow path anti-interference flowable sample pool is installed in flow of production matching with optic block and can resist the disturbance to analysis from air bubbles and precipitates, and has the advantages of convenient maintenance after disposable installing and non-substitute part constantly and non-other maintenance. Compared with the present method which draws the sample from production line depending on a pump and analyses the sample or eliminates the precipitates depending on a filter membrane, the cost of the disposable mounting of the utility model can drop down more than one half and the utility model can relief or reduce maintenance, and the cost of extended service is less than 20 percent of classical methods.

Description

The anti-interference mobile sample cell of dual flow path

Technical field

The utility model belongs to instrument on-line analysis field, the mobile sample cell when relating in particular to a kind of on-line analysis liquid sample.

Background technology

On-line analysis is one of gordian technique of control product quality, and on-line analysis needs the chemistry and the physical parameter of direct analytic sample, that is to say the pre-treatment that can not comprise any physics or chemistry.During the on-line analysis liquid sample, bubble and sediment can disturb the analysis of fluid sample, and the way more complicated that solves for example needs to extract analysis sample or blooming filtering-depositing out with pump at present, and the former increases equipment cost, and needs often to safeguard; In the pipeline of the latter's production procedure replacing of filtering membrane with safeguard relatively difficulty, and the speed that increases liquid stream influences production run.

The utility model content

The purpose of this utility model is to provide a kind of can isolate bubble and sedimentary mobile sample cell from the liquid sample of production procedure.

The utility model comprises the inside and outside pond that is made of inside and outside two bodys, interior pond constitutes the sample detection pond, its characteristics are: below the sample introduction end of interior pond, have pond injection port one near interior pond one end, simultaneously correspondingly above the sample outlet end of interior pond, the close interior pond other end has pond outlet in; Outside the top of pond sample introduction end, with the interior pond same end of injection port have an outer pond injection port, simultaneously correspondingly outside the below of pond sample outlet end, have an outer pond with the interior pond same end of outlet and go out the sample exhausr port, below, outer pond has outer stream settling basin facing to interior pond injection port, sewage draining valve is equipped with in outer stream settling basin lower end, dividing plate perpendicular to body is housed between inside and outside pond, pond body middle part, outer pond is divided into outer stream sample inlet pool and outer stream sample-out pool, the top of dividing plate has exhausr port, as the path that is mixed in gas in the fluid sample.

Two bodys in the inside and outside pond of described formation can be coaxial, also can disalignment.

The utility model is installed in the production procedure, cooperates optical system, can resist the interference to analyzing of bubble and sediment, so that the component in the accurate working sample is used for the control to production run.Have after the disposable installation easy to maintenancely, do not need often to change parts and other advantages such as maintenance.Extract from production line with existing dependence pump that sample is analyzed again or the method that relies on filtering membrane to get rid of precipitation is compared out, more than the one-step installation cost drop by half of the present utility model, and can exempt or reduce maintenance, the long-time running cost has only below 20% of classic method.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

As Fig. 1～shown in Figure 4, the utility model comprises the inside and outside pond that is made of inside and outside two bodys, these two bodys can be coaxial, also can disalignment, interior pond constitutes sample detection pond 7, below the sample introduction end of interior pond, have pond injection port 1 one near interior pond one end, simultaneously correspondingly above the sample outlet end of interior pond, the close interior pond other end has pond outlet 2 in; Outside the top of pond sample introduction end, with the interior pond same end of injection port have an outer pond injection port 3, simultaneously correspondingly outside the below of pond sample outlet end, have an outer pond with the interior pond same end of outlet and go out sample exhausr port 4, below, outer pond has outer stream settling basin 5 facing to interior pond injection port 1, sewage draining valve 11 is equipped with in outer stream settling basin 5 lower ends, dividing plate 10 perpendicular to body is housed between inside and outside pond, pond body middle part, outer pond is divided into outer stream sample inlet pool 8 and outer stream sample-out pool 9, the top of dividing plate 10 has exhausr port 6, as the path that is mixed in gas in the fluid sample.

Its workflow is specially as shown in Figure 5:

Detected sample enters Wai Chi by outer pond injection port 3 in the production line, and stream sample inlet pool 8 carries out gas, liquid, solid separation outside, and each flow process is as follows:

1) gas: the bubble floating in the testing sample enters outer stream sample-out pool 9 to exhausr port 6, goes out sample exhausr port 4 again from outer pond and turns back to and continue the production line to produce;

2) solid: the sediment in the testing sample sinks down into outer stream settling basin 5, waits for the sediment that one or more production procedures (deciding on the sample sediment) back manual unlocking sewage draining valve 11 is got rid of in the outer stream settling basin 5;

3) liquid: eliminated bubble and sedimentary testing sample and entered sample detection pond 7 by interior pond injection port 1 and detect, external light source emission detection signal sees through detection cell 7 test sample information, external detector detects the light signal that sees through sample, sample after the detection flows out sample detection ponds 7 by interior pond outlet 2, and the test sample of outflow enters outer stream sample-out pool 9 and goes out sample exhausr port 4 again from outer pond and turn back to and continue production the production line.

The principle that the utility model utilizes gas come-up, solid sediment to sink has successfully been eliminated bubble and sediment to the interference of testing process, has improved the confidence level that detects effectively.
