Abstract
The utility model relates to a fluidic measuring device. The utility model magnifies sampling signals on the test probe, and then conveys sampling signals to an analog-to-digit conversion. Then, the output digit signals are conveyed to a microprocessor, and the commands of a program memory and a data memory make the microprocessor process the measuring datum. At last, the datum is output by a digital display circuit and an acousto-optic alarm circuit. So the accurate number value and the locating scope of the electric conductivity and hardness degree of the boiler water can be given out. The fluidic measuring device has advantages of high precision, fast speed, accurate measuring, and practicable automated management.
Description
The utility model belongs to the measurement fluid means.
The water softening process is that Jiang Yuanshui (hard water) enters from water softening equipment (claiming the open type floating bed again) bottom at present, by division box, sodium type resin is floated, when former water passes through sodium type resin bed, sodion displacement in calcium wherein, magnesium ion and the resin, just make most of calcium, magnesium salts in the former water become sodium salt, thereby reduce conductivity and hardness in the former water greatly, realized the purpose of water softening; Again because of sodium salt solubleness height, be difficult for from water, separating out, therefore slow down or avoided gyp, guaranteed safe operation of the boiler, along with the continuous displacement of calcium ions and magnesium ions and sodion, then in resiniferous exchange solution, the quantity of calcium ions and magnesium ions just constantly increases, when reaching some, just lost efficacy the gradually conductivity and the hardness number of soft water of resins exchange solution layer increases, thereby reply primary resin solution is dosed the sodium chloride saline solution and carried out Regeneration Treatment, makes it recover replacing power again.
At present the hardness detection of softened water for boiler is still prolonged with chemical analysis and detect, its step is got 100 milliliters of soft water water samples earlier, inject 250 milliliters conical flask, add 2 indicator that contain 0.5% chrome black I after adding the solution of 5 milliliters of ammoniacal liquor-ammonium chloride reagent then in the water sample, in this moment this solution if hardness arranged, then be claret immediately, the water sample solution that presents claret is constantly shaken down, to have certain density standard solution disodium edta drips gradually to water sample and writes down consumption, when splashing into the standard solution of certain milliliter, water sample just presents pure blue look, be that stop splashes into, write down the consumption (milliliter number) of standard solution this moment, the shortcoming that this milliliter number is hardness (or fully hard degree) this side metering method of water sample is that water sample presents big acidity or alkaline, can chemically examine after then need neutralizing with corresponding alkalescence or acid salt; The hardness of misery sample is too big or too little then need to reduce or increase concentration of standard solution, and corresponding multiple will be dwindled or increase to measurement result also.Water temperature in winter is low, influences that chemical reaction velocity, error are big, the tired lock of this assay method, and workload is big, waste medicament and manpower, and poor with visual water sample variable color, measuring accuracy.
The purpose of this utility model provides a kind of novel device, promptly adopts microprocessor, analog converter and electronic control circuit to realize automatic monitoring to boiler feed water conductivity and hardness.
The utility model primary structure is to adopt microprocessor, analog to digital converter and other auxiliary control circuit constitute, microprocessor carries out analyzing and processing and correction to translation data, can be to the entry (hard water) and water outlet (soft water) double-range of boiler treatment facility, the two kinetic energy of conductivity and hardness carry out numeral and show, be used for indicating the leading indicator of tested water, analog to digital converter adopts 3 1/2 A/D converters to the probe measurement signal, precision and switching time with the conversion of meeting the demands, also have some auxiliary discrete component electronic circuits to form with the exception of this, the probe that detects the water sample signal is arranged, voltage signal forms circuit, signal amplification circuit, memory under program, data memory, 24 bit parallel IO interface, 4 decimal system display circuits, sound light alarming circuit and complete machine power pack.
Each functions of components and act on as follows:
Measuring power supply is that civil power is become direct supply by ac-dc conversion, except that as this device with also by directly-exchange conversion becomes oscillating AC voltage as the measurement power supply.
Detection probe be with two block sizes identical parallel be embedded in platinized platinum on glass as electrode (platinum electrode), draw two leads from platinized platinum and receive and measure on power supply and the sampled signal resistance, when platinum electrode is inserted in the water, water just presents certain resistance therebetween, it and electrical conductivity of water are inversely proportional to, by dividing potential drop relation know, on the sampled signal resistance voltage just reflected water by conductance, so reflection water is taken out the effect of detection probe that Here it is by the alternating voltage signal of conductance.The circuit of finishing above-mentioned work is exactly that voltage signal forms circuit, since the reflection conductivity the alternating signal voltage amplitude a little less than, be provided with the signal voltage amplifying circuit for making it can satisfy driving analog to digital conversion circuit operate as normal, be amplified to certain level and deliver to the input end of 3 1/2 analog to digital converters through the signal voltage amplifying circuit with the proportional analog voltage signal of tested electrical conductivity of water, analog voltage signal with certain amplitude behind analog to digital converter converts 4 BCD digital signals to, under the control of in memory under program, instructing, microprocessor successively reads in each bit data of analog to digital converter output by the A mouth (8) of 24 bit parallel I/O interfaces, check at first whether these data surpass range ability, if surpass, demonstrate the outrange signal with regard to the driving condition pilot lamp; Then microprocessor by function selector audit function options button, see the range setting and output hardness still be the setting of conductivity, change corresponding processing subroutine simultaneously over to; The limit value alert data of depositing in result after then will handling and the data memory is compared, if find to surpass alarming value, just drive warning circuit and send alarm sound, the also glittering demonstration of status indicator lamp meanwhile, no matter whether measurement result is reporting to the police or alarm range not, as long as the amount of being no more than limit (journey), microprocessor is just given display circuit data by parallel interface, show that decoding scheme becomes the signal form that is fit to the demonstration of driving LED numeral with data-switching, shows the numerical value of conductivity or hardness.The selection of IO interface and memory data all is the selection of carrying out the address by address decoder, and all processes all is to carry out under the machine instruction in memory under program is controlled.
The utility model and existing device relatively have following advantage: carry out data processing with microcomputer, precision height, fast, accurate, the practicable automatic management of measurement of speed.
