Technical field
The present invention relates to the environmental protection equipment technical field, be specifically related to the device of a kind of on-line continuous monitoring water sample pH value and automatic cleaning electrode.
Background technology
In the processing procedure of chemical industry, metallurgy, manufacturing, dyeing waste water, in order to satisfy the requirement of water technology, need the pH value of accurately continuous monitoring and each process section of control.At present, domestic employing on-line monitoring method perhaps adopts the hand sampling mensuration.
The on-line monitoring method, main mounting means comprises: immersion, lift, drainage type, side-plug-in, screw-in, the many shortcomings of the equal tool of above monitoring method; For example, because the industrial waste water calcium ions and magnesium ions is high, the PH easy fouling of popping one's head in causes the pH value measuring error, affects process operation; When the PH probe cleans again, the PH probe need to be disassembled and clean, generally adopt chemicals to clean or manual wipping, above-mentioned two kinds of cleaning methods very easily cause the probe measurement error or pop one's head in damaged.
Also have some shortcomings to be, probe is safeguarded untimely, and shorten serviceable life.
The hand sampling mensuration is to utilize hand sampling, measures the mode of cleaning to laboratory PH instrument.Also there are some shortcomings in the method, and for example, the hand sampling meeting causes monitoring to lag behind, can't Real-Time Monitoring water quality pH value; Personnel, equipment investment amount are larger.
There is no at home at present that on-line continuous is monitored automatically, the automatic report of the PH device of cleaning electrode.
Summary of the invention
The device that the purpose of this invention is to provide a kind of on-line continuous monitoring water sample pH value and automatic cleaning electrode, it can realize automatic continuous monitoring and the automatic cleaning function of pH value, eliminate the at present above-mentioned shortcoming of the monitoring method that adopts, prolong the serviceable life of PH electrode, improve the accuracy of PH electrode measurement, guarantee that the PH electrode is in the particularly normal operation of concentration organic wastewater disposal process of sewage treatment process.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises hairbrush and cleans motor 1, hairbrush 2, PH electrode 3, rotary actuator 4, linear electric motors 5, limitation travel switch 6, overflow weir 7, outlet canal 8, water inlet pipe 9, intake chamber 10, measuring flume 11 and ultrasonic cleaner 12; Hairbrush 2 cleans motor 1 with hairbrush and is connected, the other end of PH electrode 3 is connected with rotary actuator 4, measuring flume 11 is arranged on the below of rotary actuator 4, ultrasonic cleaner 12 is arranged on a side of measuring flume 11, one end of ultrasonic cleaner 12 is connected with outlet canal 8 by overflow weir 7, and the lower end of measuring flume 11 is connected with intake chamber 10, and intake chamber 10 is connected with water inlet pipe 9, measuring flume 11 is connected with ultrasonic cleaner and all is connected with limitation travel switch 6, limitation travel switch 6 and linear electric motors 5 interlockings.
When 3 to 0 ° at described rotary actuator 4 rotation PH electrodes or 90 °, rotary actuator 4 automatically locks.
Described hairbrush cleans the duration of runs of motor 1 can set adjusting.
When the present invention operates, water sample pumps into intake chamber 11 by water inlet pipe 9, along with water level constantly raises, water sample finally enters measuring flume 15 by the water inlet at intake chamber 11 tops, under the effect of the overflow water outlet of overflow weir 7, outlet canal 8, monitored water sample keeps circulation status, but water level remains unchanged substantially.At this moment, the operation that can start the machine by the touch-screen 19 on host computer picture or the switch cubicle 18, operation step order is as follows:
A, beginning (mechanical cleaning): rotary actuator 4 transmission PH electrodes 3 rotate to 0 degree, and PH electrode 3 forwards the position of hairbrush 2 to, and hairbrush cleans motor 1 running, and opens solenoid valve locks rotary actuator 4 simultaneously to PH electrode 3 water sprays simultaneously; Hairbrush 2 enters measuring process according to setting program after cleaning and finishing, and linear electric motors 5 rotate, and measuring flume 11 runs to measures the position, limitation travel switch 6 actions, and signal send PLC control linear electric motors 5 out of service.
B, measurement: rotary actuator 4 90-degree rotation that powers on, PH electrode 3 forwards the measuring position to, begins to measure, and carries signal; After the water sample pH value was measured and finished, rotary actuator 4 rotated to 0 degree position and carries out mechanical cleaning.
Mechanical cleaning, Ultrasonic Cleaning after C, the measurement: after the water sample pH value was measured and finished, rotary actuator 4 rotated to 0 degree position, and the triggering hairbrush cleans motor 1 running, carries out mechanical cleaning; After mechanical cleaning finishes, linear electric motors 5 are along counter motion, ultrasonic cleaner 12 runs to the electrode measurement position, trigger limitation travel switch 6 actions, signal send PLC control linear electric motors 5 out of service, rotary actuator 4 90-degree rotations then, and PH electrode 3 enters into 12 pairs of electrodes of ultrasonic cleaner 3 and cleans, after cleaning is finished, stop ultrasound wave work.
The present invention is because the PH electrode carries out the circulation pattern of the rear mechanical cleaning of mechanical cleaning-measurement-measurement, Ultrasonic Cleaning according to preset program, can effectively prevent foulant, grease, viscous mass parcel probe, cause measuring error, on-line continuous monitoring can not cause measuring and interrupt, and can guarantee that technique normally moves, need not the chemical cleaning probe, reduce consumption cost and drop into, automaticity is high, and is simple to operate; Easy to maintenance, almost zero dimension is protected; Its strong adaptability both had been applicable to municipal sanitary sewage, also can be used for the high concentration organic wastewaters such as industrial waste water, oilfield sewage, percolate.
