Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of circulating pump type water hardness simple and reasonable, easy to operate, that detection efficiency is high online titration detector.
The technical solution adopting is for achieving the above object such: the online titration detector of the circulating pump type water hardness providing comprises that a bottom is provided with the vertical case shell of being made by light transmissive material and the digital detection analysis circuit for detection of analysis water-like of water inlet and freeing port, logically respectively in one side direction of case shell top pack three into and (can be respectively used to titration detection reagent with the reagent burets that quantitatively peristaltic pump is connected, indicator and buffering agent), at case shell one sidewall, be provided with circulation stirring pump outward, the lower discharging tube of circulation stirring pump passes in case shell lower chamber, on a side outer wall in case shell bottom away from circulation stirring pump, be provided with the water quality signal acquisition device being formed by reflective light source and photochromic sensor, in described water quality signal acquisition device, the input end of the outer set digital detection analysis circuit of the output terminal of photochromic sensor and case shell is connected.
The further technical solution of the utility model also comprises: micro impeller Hall flow meter is housed on the water inlet pipe that passes into case shell water inlet, on the drainpipe of pass-out case shell freeing port, micro impeller Hall flow meter is housed.
The further technical solution of the utility model also comprises: the setting position on case shell outer wall top is equipped with water-level gauge.
In real work, in detector case shell, by water inlet, be filled with water sample liquid to be measured, by quantitative peristaltic pump, indicator and buffering agent injected to case shell; ON cycle mixing pump is carried out circulation stirring to aqueous humor body to be measured, during slowly splash into and detect reagent (as EDTA), utilize light source irradiating liquids, reflected light signal is delivered to digital detection analysis circuit through photochromic sensor and analyzes; Continue to stir after 30 seconds, again splash into detection reagent, analyze, and cycling is until the arrival of titration determination terminal; Finally draw Measurement results.
Compared with prior art, the advantage the utlity model has is:
(1), detect reagent, indicator and buffering agent in this online titration detector and all by quantitative peristaltic pump, by top, entered, improved the photometric condition at photometry position;
(2), the utility model water quality signal acquisition device of adopting reflective light source to form, reduced the impact of the various stray lights source in measurement environment on flash ranging, improved signal to noise ratio (S/N ratio);
(3), on stirring structure arranges, adopt circulation stirring pump formula structure, and make to stir source position relatively away from photometry original paper, can reduce the adverse effect to photometry;
(4), drainage tube portion installs impeller Hall flow meter, can realize the automatic diagnosis to drainage fault;
(5), simple and reasonable, easy to operate, detection efficiency is high, be easy to apply.
