Description
Technical field
The invention belongs to the detection technique field, be specifically related to automatic desludging and refreshing apparatus of sensitive layer of metal sensor.
Background technology
In a large amount of processes such as metallurgy, chemical industry, biological medicine, environmental monitoring; Often need detect many important parameters such as conductivity, redox, hydrogen ion content, gas concentration lwevel, some metal sensors such as main at present dependence zirconia, antimony, platinum, alloy detect.Its detection principle is through the interaction of the ion in contained ion in the material to be detected and these metals or reacts formed electromotive force and detect.
In the continuous detecting to above these processes, liquid to be detected can accumulate and forms one deck dirt at surface of metal electrode gradually, causes the sensor can't operate as normal.The responsive laminar surface of the metal of metal electrode, also can because of with the outer ion excessive concentration of the interaction in the external world or reaction, accumulation, and cause so-called " poisoning " or " dying " and can't operate as normal.
Traditional solution is to lean on artificial sensor to be disassembled, to remove dirt, to scrape off the epidermis of metal sensitive layer, makes it to expose brand-new metal level, thereby recovers its susceptibility.But this method not only bothers, and can't realize the production testing of serialization.Therefore, study a kind of need be with sensor from the device that pick-up unit removes, can in working sensor, effectively remove and refresh the layer on surface of metal dirt, just not become the important topic that the serialization production run detects.
Summary of the invention
The object of the invention is exactly the deficiency to prior art, for the metal sensor sensitive layer provides a kind of automatic, online, apparatus for eliminating sludge that desludging and refreshing is effective, simple in structure, easy to use.
The present invention includes motor, back up pad, transmission shaft, axle sleeve, spacer pin, spring, scraper plate; The sidewall setting of the vertical penetration-detection pipeline of the PTO of motor, back up pad, transmission shaft, axle sleeve, spacer pin, spring, scraper plate all are arranged on and detect in the pipeline; Back up pad is a disc, and the end of the PTO of motor is fixedly connected with the bottom center of back up pad, and an end of transmission shaft is connected with the end face center fixation of back up pad, and the sidewall of transmission shaft is fixed with spacer pin; Axle sleeve is the cylindrical shape of end face sealing, bottom surface opened, and axle sleeve is nested with outside transmission shaft, and the madial wall of axle sleeve has stopper slot vertically, and described spacer pin is corresponding with the stopper slot position, and spacer pin can slide along stopper slot; The PTO of motor, back up pad, transmission shaft, the coaxial setting of axle sleeve; Described scraper plate is the flat board that vertically is provided with, and its base is fixedly connected with the end face of axle sleeve, and the top margin of scraper plate is knife edge shape, and it is vertical with the axle sleeve end face to scrape board plane, is provided with spring between scraper plate and the back up pad, and spring is nested with outside axle sleeve; The sensitive layer of metal sensor is positioned at and detects pipeline, and the top margin of scraper plate is surperficial parallel with the sensitive layer of metal sensor, and the position is corresponding, and the top margin length of scraper plate is greater than the maximum diameter of sensitive layer.
Advantage of the present invention is: the 1) scraper plate of this device, can differently according to the hardness of metal sensitive layer select different materials for use, to guarantee both effectively to take out stains, refresh metal surface, unlikely again damage metal sensitive layer.2) this device adopts rotor segment, realizes striking off of dirt and refreshing of metal surface, and effect is good again, and structure is simple again, and is not fragile.3) adopt spring that scraper plate tightly is pressed on the metal sensitive layer, not only simply but also practical.4) can realize the continuously-running duty that metal sensor one edge work, scale removal on one side and sensitive layer refresh.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the enlarged diagram of the A part of Fig. 1;
Fig. 3 is that the B-B of Fig. 2 is to schematic cross-section.
Embodiment
Like Fig. 1, shown in 2 and 3, automatic desludging and refreshing apparatus of sensitive layer of metal sensor comprises motor 4, back up pad 9, transmission shaft 8, axle sleeve 11, spacer pin 7, spring 10, scraper plate 5; The sidewall setting of the vertical penetration-detection pipeline 2 of the PTO of motor 4, back up pad 9, transmission shaft 8, axle sleeve 11, spacer pin 7, spring 10, scraper plate 5 all are arranged on and detect in the pipeline 2; Back up pad 9 is a disc, and the end of the PTO of motor 4 is fixedly connected with the bottom center of back up pad 9, and an end of transmission shaft 8 is connected with the end face center fixation of back up pad 9, and the sidewall of transmission shaft 8 is fixed with spacer pin 7; Axle sleeve 11 is the cylindrical shape of end face sealing, bottom surface opened, and axle sleeve 11 is nested with outside transmission shaft 8, and the madial wall of axle sleeve 11 has stopper slot 6 vertically, and described spacer pin 7 is corresponding with stopper slot 6 positions, and spacer pin 7 can slide along stopper slot 6; The PTO of motor 4, back up pad 9, transmission shaft 8, axle sleeve 11 coaxial settings; Described scraper plate 5 is the flat board that vertically is provided with, and its base is fixedly connected with the end face of axle sleeve 11, and the top margin of scraper plate 5 is knife edge shape, and scraper plate 5 planes are vertical with axle sleeve 11 end faces, are provided with spring 10 between scraper plate 5 and the back up pad 9, and spring 10 is nested with outside axle sleeve 11; The sensitive layer 3 of metal sensor 1 is positioned at and detects pipeline 2, the sensitive layer 3 of the top margin of scraper plate 5 and metal sensor 1 surperficial parallel, and position correspondence, and the top margin length of scraper plate 5 is greater than the maximum diameter of sensitive layer.The difference of the top margin length of scraper plate and the maximum diameter of sensitive layer is 1.5mm.Scraper plate adopts the epoxy resin board (being circuit board material) of embedded nylon wire, the about 3～5mm of scraper thickness.
Motor adopts slow speed motor, and rotating speed is controlled in 100 rev/mins.Select 70TDY-C type " synchronous motor ", 60 rev/mins of its rotating speeds, power 24W, voltage 220V.
To the demanding occasion of scale removal precision, motor is in running order always.In fact scale removal, cleaning are less important, importantly sensitive layer are scraped newly, and original saturated top layer metal is scraped off, and expose metal brand-new, that also do not react.The stopping time opens in the time of also can letting motor, gets final product through program.
The concrete course of work of the present invention is:
Needs carry out scale removal and refresh to the metal sensor sensitive layer when, open motor, transmission shaft drives the axle sleeve rotation through spacer pin, and axle sleeve drives the scraper plate that is fixed on above it and rotates together; Because the effect of spring, spacer pin moves at stopper slot vertically, makes the cutting edge of a knife or a sword mouth of scraper plate closely contact with sensitive layer; Like this, the scraper plate of rotation is just wiped the dirt on sensitive layer surface and old sensitive layer off together, exposes brand-new metal level.
