Technical field
The present invention relates to 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, manufacture, dyeing waste water, in order to meet the requirement of water technology, need to monitor continuously and control accurately the pH value of each process section.At present, domestic employing on-line monitoring method, or adopt hand sampling mensuration.
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 industrial waste water calcium ions and magnesium ions is high, the PH easy fouling of popping one's head in, causes pH value measuring error, affects process operation; When PH probe cleans again, PH probe need to be disassembled and cleans, generally adopt chemicals to clean or manual wipping, above-mentioned two kinds of cleaning methods very easily cause probe measurement error or pop one's head in damaged.
Also have some shortcomings to be, probe is safeguarded not in time, shortening in serviceable life.
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, for example, hand sampling meeting causes monitoring to lag behind, cannot 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 report of the PH device of cleaning electrode automatically.
Summary of the invention
The object of this invention is to provide the device of 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 above-mentioned shortcoming of the monitoring method that adopts at present, extend the serviceable life of PH electrode, improve the accuracy of PH electrode measurement, ensure that 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 all connected with limitation travel switch 6 with ultrasonic cleaner 12, and limitation travel switch 6 is interlocked with linear electric motors 5.
When described rotary actuator 4 rotates 3 to 0 °, PH electrode 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.Now, can be by the operation that starts the machine of the touch-screen 19 on host computer picture or 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, hairbrush cleans motor 1 and turns round, and opens solenoid valve is sprayed water to PH electrode 3 simultaneously, locks rotary actuator 4 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 position, and limitation travel switch 6 moves, and it is out of service that signal send PLC to control linear electric motors 5.
B, measurement: rotary actuator 4 90-degree rotation that powers on, PH electrode 3 forwards measuring position to, starts to measure, and carries signal; After the measurement of water sample pH value finishes, rotary actuator 4 rotates to 0 degree position and carries out mechanical cleaning.
Mechanical cleaning, Ultrasonic Cleaning after C, measurement: after the measurement of water sample pH value finishes, rotary actuator 4 rotates to 0 degree position, trigger hairbrush cleaning motor 1 and turn round, and carries out mechanical cleaning; After mechanical cleaning finishes, linear electric motors 5 are along counter motion, ultrasonic cleaner 12 runs to electrode measurement position, triggering limitation travel switch 6 moves, it is out of service that signal send PLC to control linear electric motors 5, then rotary actuator 4 90-degree rotations, and PH electrode 3 enters into ultrasonic cleaner 12 electrode 3 is cleaned, after cleaning completes, stop ultrasound wave work.
The present invention is because PH electrode carries out mechanical cleaning-measurement-measurement circulation pattern of mechanical cleaning, Ultrasonic Cleaning afterwards 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 ensure that technique normally moves, pop one's head in without chemical cleaning, reduce consumption cost and drop into, automaticity is high, simple to operate; Easy to maintenance, almost zero dimension is protected; Its strong adaptability, had both been applicable to municipal sanitary sewage, also can be used for the high concentrated organic wastewaters such as industrial waste water, oilfield sewage, percolate.
