Abstract
The utility model discloses an online continuous pH measuring meter, belonging to a pH value detector. The online continuous pH measuring meter is mainly technically characterized in that a sampling inlet manifold connected with a sampling pump is arranged in a production tank, the sampling inlet manifold is further connected with a condensation tank and a measuring pipe, a temperature measuring element and a pH electrode are arranged on a measuring tube, and conductors of the temperature measuring element and the pH electrode are connected with a pH digital control display instrument. A sampling outlet pipe of the sampling pump returns to the production tank, and the condensation tank and the measuring tube are connected with a condensing water tube. Through the online continuous pH measuring meter, the pH value can be accurately measured in time in the continuous production process. The amount of alkaline liquor can be accurately controlled so as to ensure the production stability. In addition, the burden of operating personnel can be lightened.
Description
Technical field: the utility model relates to a kind of pH meter, but the pH meter that especially a kind of on-line continuous is measured.
Background technology: to sink in noble metal is produced purification process silver, deironing, sink copper, the nickel that sinks, need control the amount of alkali lye in order to reach best effect, control the pH value with this.What take in the past is pH detection paper pH, and the deficiency of the method is: 1, error is large, can not accurately show the pH value of solution.2, be subjected to the solution temperature variable effect larger.3, operating personnel generally can measure once at set intervals, can not in time control continuously the solution pH value like this.
Summary of the invention: the purpose of this utility model is the pH meter that a kind of on-line continuous of design is measured, and it is Measurement accuracy pH value continuously, and temperature control equipment is arranged again, has overcome the shortcoming that prior art exists.Adopted following technical scheme: the pH meter that on-line continuous is measured comprises cooling device, measuring sensor and Displaying Meter for this reason.In producing groove, the sampling inlet pipe that is connected with sampling pump is arranged, also be connected with drainer and measuring tube on the sampling inlet pipe, temperature element and pH electrode are housed on measuring tube, and temperature element is connected wire and is connected the digital control display instrument of pH with the pH electrode, and the sampling of sampling pump goes out pipe and returns to the production groove; Be connected with respectively the condensate water rising pipe and control the condensate water water inlet pipe of solenoid valve with condensate water on drainer and measuring tube.
The pH meter that on-line continuous is measured can be in continuous flow procedure promptly and accurately pH value determination.Thereby accurately control the amount of alkali lye, guarantee to produce stable carrying out.Alleviated simultaneously operating personnel's burden.
Description of drawings: Fig. 1 is the structural representation of the pH meter of on-line continuous measurement.
Embodiment: be further described below in conjunction with accompanying drawing.
As shown in drawings, the pH meter that on-line continuous is measured comprises cooling device, measuring sensor and Displaying Meter.Have in producing groove 4 and are connected the sampling inlet pipe 5 that connects with sampling pump, sampling pump is selected the membrane pump of 40L/H.Also be connected with drainer 7 and measuring tube 8 in sampling on inlet pipe, temperature element 10 and pH electrode 11 are housed on measuring tube, temperature element is connected wire and is connected the digital control display instrument 13 of pH with the pH electrode, and the pH value of temperature value and measurement is shown on display instrument.The sampling of sampling pump goes out pipe 6 and returns to the production groove; Be connected with respectively condensate water rising pipe 1 and control the condensate water water inlet pipe 2 of solenoid valve 3 with condensate water on drainer and measuring tube.Condensate water is controlled solenoid valve 12 and is closed when pH meter works, and condensate water is controlled solenoid valve 3 and opened that to carry out solution cooling, to control the detected solution temperature in 30 degree left and right.In the pH meter course of work, the internal processes of the every 5 hours digital control display instruments of pH will carry out auto-flushing once to pH meter, cleans the pH electrode surface, guarantee to measure accurately.Condensate water control solenoid valve 3 cuts out when automatic or manual is washed by water, and condensate water is controlled solenoid valve 12 and opened, and carries out pH electrode and flushing of pipeline.When temperature was spent higher than 40, the internal processes of the digital control display instrument of pH quit work pH meter and reports to the police, and should check whether condensation portion is normal this moment.
