The invention solves the problem of detection accuracy of a traditional liquid level detector and has the characteristics of low manufacture cost, simple structure, and the like.
Description
Technical field:
The present invention relates to a kind of liquid level detector, belong to the electrolytic water device field.
Background technology:
At present, oxyhydrogen generator all is to carry out work by brine electrolysis, its electrolysis installation adopts the form of electrolytic tank to carry out brine electrolysis substantially and produces hydrogen or oxygen gas, in electrolytic process, need to monitor in real time the degree of depth of electrolytic solution in electrolyte tank, electrolytic solution too much can cause electrolysis normally to carry out, even break down, electrolytic solution crosses that I haven't seen you for ages causes the gas production rate deficiency, existing liquid level detector has float-ball type, electronic type, multiple checkout equipment such as pointer-type, because the electrolytic solution in the electrolyte tank internal liquid and gaseous mixture when work are to be in the state that is similar to boiling, above-mentioned Level Detection equipment can't normally detect the actual grade of electrolytic solution in the electrolyte tank.
Summary of the invention:
The invention provides a kind of liquid level detector, the effective degree of depth of electrolytic solution in the electrolyte tank during testing state, and can guarantee the accuracy of detection.
A kind of liquid level detector comprises spiral shell splash-proof casing, nut, probe and nut cap, and peripherals is electrolyte tank, electric wire and control circuit; Wherein splash-proof casing is that uncovered is columnar structured, and upper end open place inwall is processed with screw thread, and the above uniform aperture of a row is circumferentially all arranged at splash-proof casing screw thread bottom and splash-proof casing bottom; There is a stage at nut cylindrical middle part, and all there is screw thread at the two ends up and down of stage, and there is a counterbore at the nut middle part, and the aperture of three perforations is radially arranged in the counterbore; That probe has is long, in, short three, the longest is reference probe, middle length be the lower limit probe, the shortest be upper limit probe, the nut cap middle part has a through hole; Its annexation is: probe by length, in, short being contained in successively in three apertures of nut, nut lower end and splash-proof casing screw by threaded engagement, nut upper end and nut cap screw by screw thread.Three probes are connected with electric wire respectively, and electric wire links to each other with control circuit by the through hole on the nut cap, and the liquid level detector integral installation is in being equipped with the electrolyte tank of electrolytic solution.
The material that nut and splash-proof casing adopt is a teflon, this material has very good hydrophobe, when electrolytic solution splashes its surface, can't form little liquid level on its surface, therefore effectively avoid the electrolytic solution probe that in the process of splashing, misleads, liquid level detector was lost efficacy.
Working method: liquid level detector integral body is placed in the electrolyte tank, and it is inner and be consistent with liquid level in the container that the gas in the electrolyte tank, the aqueous mixtures through hole by the splash-proof casing lower end enters splash-proof casing; When liquid level when middle long probe is following, probe shows that by control circuit container is in exsiccosis; When liquid level was between the shortest and middle long probe, this moment, liquid level was in reasonable liquid level; When liquid level surpassed the shortest probe, this moment, liquid level just was in water state.Therefore, get final product the scope of the required control of liquid level in the detection receptacle by the length of adjusting probe.Because the gas-liquid mixture in the electrolyte tank often is in the state of seething, so the aperture on splash-proof casing top has the function of exhaust, and can guarantee that the liquid of splash-proof casing inside maintains a relatively stable state.
Beneficial effect: the invention solves the accuracy problems that traditional liquid level detector detects, have low cost of manufacture, characteristics such as simple in structure.
Description of drawings
Fig. 1 is the structural representation of liquid level detector of the present invention.
Wherein: 1-nut cap, 2-nut, 3-reference probe, 4-splash-proof casing.
Embodiment
As shown in Figure 1, a kind of liquid level detector comprises nut cap 1, nut 2, probe and splash-proof casing 4, and peripherals is electric wire and control circuit; Wherein splash-proof casing 4 is that uncovered is columnar structured, and upper end open place inwall is processed with screw thread, and four rows and the uniform aperture of 14 rows are circumferentially arranged respectively at splash-proof casing 4 screw thread bottoms and splash-proof casing 4 bottoms; There is a stage at nut 2 cylindricals middle part, and all there is screw thread at the two ends up and down of stage, and there is a counterbore at nut 2 middle parts, and the aperture of three uniform perforations is radially arranged in the counterbore; That probe has is long, in, short three, the longest is reference probe 3, middle length be the lower limit probe, the shortest be upper limit probe, nut cap 1 middle part has a through hole; Its annexation is: probe by length, in, short being contained in successively in three apertures of nut 2, nut 2 lower ends and splash-proof casing 4 screw by threaded engagement, nut 2 upper ends and nut cap 1 screw by screw thread; Three probes are connected with electric wire respectively, and electric wire links to each other with control circuit by the through hole on the nut cap 1; The material that nut 2 and splash-proof casing 4 adopt is a teflon, and probe adopts stainless steel.
Working method: liquid level detector integral body is placed in the electrolyte tank, and it is inner and be consistent with liquid level in the container that the gas in the electrolyte tank, the aqueous mixtures through hole by splash-proof casing 4 lower ends enters splash-proof casing 4; When liquid level when middle long probe is following, probe shows that by control circuit container is in exsiccosis; When liquid level was between the shortest and middle long probe, this moment, liquid level was in reasonable liquid level; When liquid level surpassed the shortest probe, this moment, liquid level just was in water state.Therefore, get final product the scope of the required control of liquid level in the detection receptacle by the length of adjusting probe.Because the gas-liquid mixture in the electrolyte tank often is in the state of seething, so the aperture on splash-proof casing 4 tops has the function of exhaust, and can guarantee that the liquid of splash-proof casing 4 inside maintains a relatively stable state.
