Abstract
The utility model relates to a reagent measuring cup for a water quality on-line analyzer, which belongs to a measuring instrument for calibrating the volume of liquid. The measuring cup is mainly composed of a peristaltic pump, a three-way electromagnetic valve, a measuring cup shell and a reagent measuring pipe, wherein, a liquid inlet pipe is installed in the inlet of the peristaltic pump, the outlet of the peristaltic pump is connected with the three-way electromagnetic valve by using a connecting pipe, a liquid outlet pipe is installed in the lower passage of the three-way electromagnetic valve, by using a pipe joint, the upper passage of the three-way electromagnetic valve is connected with the lower end of the reagent measuring pipe which is above the upper passage of the three-way electromagnetic valve, the reagent measuring pipe is inserted into the inner cavity of the measuring cup shell from the bottom of the measuring cup shell, an overflow pipe is installed below the measuring cup shell, and the overflow pipe is in parallel alignment with the bottom surface of the measuring cup shell. By applying the reagent measuring cup, the measured data of chemical oxygen demand is more accurate than the data which is measured by the water quality on-line analyzer COD by using a peristaltic pump, the accuracy of the reagent measuring cup is in a leading position in the COD products of more than twenty domestic enterprises, and proportional sampling is realized. The utility model has the advantages of simple structure, convenient manufacture, convenient installation, convenient maintenance, and low cost. The utility model can also be matched with other monitoring analytical instruments.
Description
(1) technical field
The utility model relates to the water quality monitoring environmental technology field, particularly is a kind of water quality online analyzer reagent jigger.Main and the supporting use of water-quality COD in-line analyzer.
(2) background technology
The water-quality COD in-line analyzer is used for the chemical oxygen consumption (COC) of real-time monitoring analysis sewage effluent; judge pollution level with this to water; both provided environmental pollution self check data for sewage discharge enterprise; also provide Back ground Information for environmental administration's strengthen environmental protection and improvement, and according to this as the punishment charge foundation of environmental pollution enterprise.Therefore both sides pay much attention to the parasexuality of monitoring analysis instrument data.Traditional water-quality COD in-line analyzer all utilizes the payment foundation of peristaltic pump as reagent, and is accurate inadequately, causes the data error that records bigger, and is difficult to realize equal proportion sampling.Annotate the plug pump as the reagent payment foundation if adopt, instrument cost is higher, is unfavorable for the large-scale popularization application.By retrieval, find no relevant patent documentation.So far also not seeing more advanced like product is applying.
(3) summary of the invention
The purpose of this utility model just is to provide a kind of water quality online analyzer reagent jigger, replace the long-term peristaltic pump that uses with this, further improve metering precision, and realize equal proportion sampling, guarantee that chemical oxygen consumption (COC) data that the water-quality COD in-line analyzer records more accurately and reliably.
This reagent jigger is made up of peristaltic pump, three-way solenoid valve, jigger shell, reagent gauge line, feed tube, drain pipe, connecting pipe and discharger.Feed tube is installed in the peristaltic pump import, and its outlet links to each other with the horizontal channel of three-way solenoid valve with connecting pipe.The lower channel of three-way solenoid valve is installed drain pipe, and upper channel links to each other with the reagent gauge line lower end of pipe adapter with its top.The reagent gauge line upwards inserts the inner chamber of jigger shell from jigger shell bottom.Run-down pipe is installed under the jigger shell, and concordant with jigger shell bottom surface.
The jigger shell of above-mentioned water quality online analyzer reagent jigger is a cylindrical hollow closed glass cup.Its bottom surface has two circular holes, and one is used to insert the reagent gauge line, and another is used to install run-down pipe, and jigger shell, reagent gauge line and run-down pipe three are become one.
Feed tube, connecting pipe, drain pipe, run-down pipe in the above-mentioned water quality online analyzer reagent jigger all adopt the anti-corrosive rubber pipe.The spool of three-way solenoid valve adopts corrosion-resistant plastic.
Use this reagent jigger than using peristaltic pump, the chemical oxygen consumption of sewage data accuracy that the water-quality COD in-line analyzer is recorded obviously improves.Its degree of accuracy maintains the leading position in the tame COD product more than 20 at home, and has realized equal proportion sampling.Its structure is very simple, make, install and maintenance all very convenient, cost is lower, also can with the supporting use of other monitoring analysis instrument of water quality.
(4) description of drawings
Accompanying drawing is whole the composition and scheme of installation of the present utility model.
In the accompanying drawing, the 1st, peristaltic pump, the 2nd, three-way solenoid valve, the 3rd, jigger shell, the 4th, reagent gauge line, the 5th, feed tube, the 6th, run-down pipe, the 7th, drain pipe, the 8th, connecting pipe, the 9th, pipe adapter.
(5) embodiment
As shown in drawings, this reagent jigger mainly is made up of peristaltic pump 1, three-way solenoid valve 2, jigger shell 3 and reagent gauge line 4.Feed tube 5 is installed in peristaltic pump 1 import, and its outlet links to each other with the horizontal channel of three-way solenoid valve 2 with connecting pipe 8.The lower channel of three-way solenoid valve 2 is installed drain pipe 7, and upper channel links to each other with reagent gauge line 4 lower ends of pipe adapter 9 with its top.Reagent gauge line 4 upwards inserts jigger shell 3 inner chambers from jigger shell 3 bottoms.Run-down pipe 6 be installed in jigger shell 3 under, and concordant with jigger shell bottom surface.
Its dynamic duty process is: at first carry out sampling preparation, catalyzer, oxygenant, blank sample, water sample etc. are injected reagent gauge line 4 respectively, do circulating sampling one time, can prevent to have in the reagent of reagent gauge line 4 bubble to exist like this.Under control system control, start peristaltic pump 1 then, reagent injects reagent gauge line 4 through connecting pipe 8, three-way solenoid valve 2 and pipe adapter 9.When reagent was full of reagent gauge line 4, the reagent that overflows from gauge line 4 tops just flowed out from the run-down pipe 6 of jigger shell 3 bottoms.The reagent that overflows is detected by liquid-detecting, and sends control signal immediately peristaltic pump 1 is quit work.Three-way solenoid valve 2 is under control signal control, be transformed into reagent gauge line 4 and clear up the lower channel that cup communicates, reagent in the reagent gauge line 4 just all flows into the cup of clearing up of below by pipe adapter 9, three-way solenoid valve 2 and drain pipe 7, a reagent sampling finishes, and three-way solenoid valve 2 is transformed into original state again and waits for sampling next time.Because the amount of capacity of reagent gauge line 4 can be set at fixed standard value on request, each reagent sampling all is this normal capacity, thus both accurately reliable, realized equal proportion sampling again.
