Description
Technical field
The utility model relates to a kind of sexavalent chrome online automatic monitor.
Background technology
At present; The analyst measures chromic content in the water sample through visual colorimetry, and visual colorimetry commonly used is a standard series method, and the determinand standard solution of promptly using different amounts are in identical one group of color comparison tube; By the analytical procedure colour developing, be made into the color standard color range of alternation gradually earlier.Sample solution also under identical condition, develops the color and the standard color range is made comparisons, visual that the most close a standard of color and luster of finding out; By the amount of contained standard solution wherein; Calculate and confirm components contents to be measured in the sample, but the subjective error of visual colorimetry is big, accuracy of measurement is lower; Need repeatedly to measure, efficiency of measurement is low.
Summary of the invention
The purpose of the utility model is in order to overcome above deficiency, provide a kind of simple in structure, failure rate is low, the sexavalent chrome online automatic monitor of long service life.
The purpose of the utility model realizes through following technical scheme: a kind of sexavalent chrome online automatic monitor; Comprise peristaltic pump; Peristaltic pump links to each other with the photoelectrometer buret through flexible pipe, and the length of photoelectrometer buret is 18-20cm, and the photoelectrometer buret links to each other with the hyperchannel selector valve through pipe; The hyperchannel selector valve is connected with digestion device through pipe, and digestion device links to each other with solenoid valve through pipe.
The further improvement of the utility model is: the hyperchannel selector valve is provided with a plurality of passwaies; Wherein any passway on the hyperchannel selector valve links to each other with the photoelectrometer buret through pipe, and any on the hyperchannel selector valve is communicated with the road junction and links to each other with digestion device through pipe.
The further improvement of the utility model is: pipe is fine reagent pipe, and fine reagent pipe can be the fluorine plastic tube of 1.2mm internal diameter.
The utility model compared with prior art has the following advantages: the utility model adopts unique technological design, measures chromic content in the water sample through photoelectric colorimetry; Utilize the photoelectrometer buret to overcome the defective that peristaltic pump flexible pipe wearing and tearing precision reduces, shutting out the light through liquid causes the change of signal, accurately realizes the quantitative of reagent; The cooperation of fine reagent pipe and electro-optical system realizes the trace reagent accurate quantification, significantly reduces the reagent use amount.The single channel selector valve that the present invention adopts is compared with other solenoid valves, has dead volume still less, the advantage that antiseptic property is high, compressive resistance is high; The reagent sample introduction adopts the mode that the peristaltic pump negative pressure sucks and malleation blows out; There is an air cushioning district between reagent and flexible pipe, guarantees that liquid does not contact with pump line, greatly reduce the requirement of flexible pipe; And stopped the pollution of pump line, improved peristaltic pump serviceable life and instrumental analysis precision reagent; The used fine reagent pipe of instrument adopts the fluorine plastic tube of 1.2mm internal diameter, cuts in advance and blocks water kind particle before getting into the single channel selector valve, ensures the normal operation of single channel selector valve.
