Background technology
In recent years, for the pH-value content measurement for the department such as oil, petrochemical complex, various different pH value method occurs, and the mensuration of chemical industry solutions product acid base number generally adopts the method for hand sampling, chemistry titration, due in production scene sampling, analyze to laboratory, analysis result is caused to lag behind production, delay optimised process and adjust opportunity, bring corresponding difficulty to the control of technique, product quality can not effectively be ensured.If bad environments, such hand sampling number of times is limited, can not continuous on-line detection, and many human factors are difficult to ensure measuring accuracy; Simultaneously long from being measured to change solution concentration required time, solution concentration fluctuation is large.Measured the pH value of solution by the change of pH test paper color, the interference of the materials such as solution intrinsic colour or protein can be subject to and be limited to adopt, being only applicable to the measurement being greater than 0.5pH value; Then cannot carry out for the measurement being less than 0.5pH value.
No matter above-mentioned be measuring method or to use instrument all to exist certain unreasonable.
Utility model content
The object that the utility model proposes is to overcome above-mentioned the deficiencies in the prior art, provide a kind of not only can improve chemical industry solutions product measurement of ph value accuracy but also can the microcomputer pH value instrument of automatic or manual decision titration end-point.This microcomputer pH value instrument structure and pH value functionally have very large breakthrough and optimization relative to traditional instrument.
A kind of microcomputer pH value of the utility model instrument, comprises automatic control unit, computer display, host computer.Automatic control unit comprises acid solution adding set, alkali lye adding set, induction installation, titration apparatus, intracellular signaling device.Induction installation one end electrical connection titration apparatus, one end is electrically connected with acid solution adding set and alkali lye adding set, and is electrically connected with host computer, forms added automatically system.Intracellular signaling device one end is electrically connected with titration apparatus, and the other end is electrically connected with host computer.
Preferably, one end that intracellular signaling device is electrically connected with titration apparatus comprises pH-value probe.
Preferably, titration apparatus comprises stirring dissolving device, buret, thermometer.
Preferably, buret is glassware, and volume is 0.01ml-10ml.
Preferably, stir dissolving device to comprise stirred vessel, stir magnetite rod, gland bonnet, magnetic stirrer, described stirred vessel is placed in above magnetic stirrer, described gland bonnet is placed in stirred vessel upper surface, gland bonnet comprises 5 holes, be electrically connected acid solution adding set, alkali lye adding set respectively, stir magnetite rod, pH-value probe, buret; Described stirring magnetite rod is placed in gland bonnet center, the mode be connected with loose-leaf with gland bonnet.
Host computer in the utility model, by carrying out record to the electrode potential in titration process and titration volumes, finds out the volume of the standard titration solution of equivalent point and correspondence automatically, thus obtains the content of pH-value in sample.
Accompanying drawing explanation
Fig. 1 is microcomputer pH value instrument planimetric map.
In figure, 1 is computer display, and 2 is host computer, 3 is intracellular signaling device, and 4 is thermometer, and 5 is titration hole, 6 is pH-value probe, and 7 for stirring magnetite rod, and 8 is stirred vessel, 9 is magnetic stirrer, and 10 is gland bonnet, and 11 add pipe for acid solution, 12 add pipe for alkali lye, 13 is alkali liquor container, and 14 is acid liquor container, and 15 is induction installation.
Embodiment
A kind of microcomputer pH value of the utility model instrument, comprises automatic control unit, computer display 1, host computer 2.Automatic control unit comprises acid solution adding set, alkali lye adding set, induction installation 15, titration apparatus, intracellular signaling device 3.Induction installation one end electrical connection titration apparatus, one end is electrically connected with acid solution adding set and alkali lye adding set, and is electrically connected with host computer 2, forms added automatically system.Intracellular signaling device 3 one end is electrically connected with titration apparatus, and the other end is electrically connected with host computer 2.Thermometer 4, by the temperature in surveying instrument, ensures that measurement environment is carried out at normal temperatures, thus makes measurement more accurate.
By buret pipette samples in the utility model, instill the sample of about 2ml at titration hole 5 place, titration hole is use stopper to be clogged at not titration sample.After sample instillation stirred vessel 8, stir magnetite rod 7 Stirring solution, magnetic stirrer 9 plays the function of auxiliary concussion simultaneously, to ensure the homogeneity of solution, thus measures pH-value more accurately.Magnetic stirrer 9 is electrically connected with stirred vessel 8, and connect induction installation 15, induction installation can respond to the volume of solution in stirred vessel 8, thus is transferred to host computer 2, calculates pH-value by related software simultaneously.PH-value probe 6, by measuring the pH-value in stirred vessel 8, has measured and has passed to host computer 2 by intracellular signaling device 3 conversion.Host computer 2 receives signal and the numerical value of intracellular signaling device 3 and induction installation 15 transmission, is calculated and depict the pH-value curve of mensuration by the software of host computer 2 li.
After the pH-value of working sample, the solution in stirred vessel 8 is acidity or the alkalescence of sample.Host computer 2 will to calculate in needs and the acidity of solution or alkaline volume in stirred vessel, acid solution adding set or alkali lye adding set is driven by induction installation 15, for stirred vessel adds acid or akaline liquid neutralization, thus ensure that the cyclicity that instrument uses.Meanwhile, if when induction installation 15 senses that solution in stirred vessel 8 is more than 50ml, be transferred to host computer 2, host computer 2 can make warning prompt by computer display 1, to ensure the accuracy of whole measurement.
These are only the utility model preferred embodiment, therefore can not limit the scope of the utility model enforcement according to this, the equivalence namely done according to the utility model description changes and decoration, all should belong in the scope of the utility model covering.
