B group electrode container retaining acid lid 03, B group positioning of electrode ring 05, B group electrode container 13, B group positioning of electrode pressure cylinder 43, B group electrode pressure cylinder handwheel 29 roles are installation sites of fixed electorde in this device, when preventing B group electrode 01 with 13 motions of B group electrode container about and swing up and down.
In this device, in B group electrode lower seal 02, the B group electrode on O-ring seal 06, the B group electrode O-ring seal 07 role be sealing B group electrode tip 44, keep B group electrode tip 44 long-term dry.
The effect of B group electrode lower seal 02 is to chew 10 cleaning fluids that spray by spray acid when preventing cleaning electrode to enter into B group electrode container 13 inner chambers by the gap that B group electrode container retaining acid lid 03 and B organize electrode 01,
O-ring seal 06 is identical with B group electrode lower seal 02 in the B group electrode, plays the double shield effect.
Acting as of O-ring seal 07 prevents that water vapor and water droplet from entering into B group electrode container 13 inner chambers from the through hole that B organizes electrode pressure cylinder handwheel 29 and B group positioning of electrode pressure cylinder 43 on the B group electrode.
Electrode purging system of the present invention by the cleaning fluid storage tank that is installed in sampled measurements chamber bottom, advance that acid chews 42, acid discharge chews 41, infusion pump (not shown) and liquid reversal valve 34 constitute, cleaning fluid storage tank and body 35 are made of one, and keep off sour glass bottom plate 08 and play the spacing up and down effect that the sour glass 12 of retaining is fixed with the sour fixed head 14 on glass of retaining in device.
Keeping off sour glass 12 effects is that cleaning fluid is splashed to outside the body when preventing cleaning electrode, the 12nd, and the glass material manufacturing can see through the cleaning situation that the sour glass 12 of retaining is observed electrode during the device long journey.Spacing and be fixed on the body 35 when keeping off sour fixed head on glass 14 and installing by register pin 15.
The surveying work process and the principle of double-glass pH electrode continuous detection apparatus of the present invention are as follows:
Sampling groove in the measuring chamber places on the support 45, and tested fluid enters or flows through the sampling groove, and B group electrode tip 44 puts in the sampling groove and detects, and collects data-signal and is sent to computer continuously by cable and handle.And this moment, A electrode 11 has risen to predetermined height, and the sensor of stop means is pressed close to upper limit Hall switch 26, and (move on the A group electrode 11, signal is passed to the computer of pulpit by lead) just stops operating after B group motor 32 is received signal.Measure when B group electrode 01 and to finish, motor transmission shaft is equipped with tooth bar 41 and rises, and also drives the electrode purging system in the uphill process and turns an angle, and makes and hydrojet is chewed 10 and aligned B group electrode 01.The computer instruction infusion pump starts then, and the cleaning fluid with certain pressure is chewed 10 from hydrojet and ejected B group electrode 01 is cleaned.Cleaning fluid after the injection is flowed down by the cleaning fluid refluxing opening.In order to prevent that liquid liquid from leaking, the electrode purge chamber fences up with cloche 12.After time, computer instruction B organizes electric motor starting through preset detection, and B group motor gear 39 and B group tooth bar 41 move down.B group electrode 01 just puts in measuring chamber.After dropping to predetermined altitude, the sensor of stop means is pressed close to B lower class limit position Hall switch 30, just stops operating after B group motor is received signal, and the B electrode begins to enter the detection-phase of awaiting orders.Through certain hour, hold signal stabilization after, under computer instruction, reason A group electrode 11 provides detection signal just to automatically switch to by B group electrode.Like this, detection signal does not interrupt, and reaches the purpose of continous-stable.
Be to guarantee that liquid barrier 09 among the figure and hydrojet are chewed all to be in two electrode middles when electrode is height-rise or high-fall.Preventing that electrode from chewing with liquid barrier and hydrojet in motion process bumps and damages electrode.Coulisse 18 has double flute, A organizes electrode and moves groove of use, and B group electrode moves and uses a groove, when B group break-in pin, electrode move up and down coulisse, A organizes the rotation that the break-in pin has limited another groove of coulisse, and liquid barrier and hydrojet are chewed be between two electrodes, guarantee electrode safety.
Compare with the double-glass pH electrode continuous detection apparatus before the inventor, it is more accurate that full-automatic detection device of double-glass pH electrode of the present invention has measurement, it is easier to operate, and the zero failure operation of sugar refinery on-line measurement has reached a press for extracting juice season continuous operation need not change parts.
