Abstract
The invention discloses a device for detecting the liquid level of a magnesium electrolysis bath. The top of a cover board (9) of a magnesium collecting room of the electrolysis bath is provided with a hole. A flange joint pipe (3) is welded correspondingly to the hole and is welded with a flange (4) which is connected with a stainless steel flange cover board (5) with a hole and a polyfluortetraethylene clapboard (6). Three stainless steel bars (1) with different length pass through the flange cover board (5) and the polyfluortetraethylene clapboard (6) and are connected by a nut (7). Every stainless steel bar (1) leads out a lead wire (8) which is connected with a relay loop and a control system; wherein, the lower end of one stainless steel bar (1) is flush with the set highest liquid level; the lower end of another stainless steel bar (1) is flush with the set lowest liquid level; the lower end of the other stainless steel bar (1) is lower than the lowest liquid level. A carborundum protection tube is arranged among the flange cover board, the polyfluortetraethylene clapboard and the stainless steel bars.
Description
Technical field
The present invention relates to the indoor molten magnesium liquid liquid level detection device of electrolyzer collection magnesium in a kind of magnesium eletrolysis production process.
Background technology
In the electrolytic magnesium production process, the indoor molten magnesium liquid level gauging of electrolyzer collection magnesium all is a difficult problem all the time, and reason is that temperature and is filled the air a large amount of chlorine up to 720 ℃ in the groove in the electrolyzer, has very severe corrosive.Adopt conventional typing level gage product, as radar level gage, ultrasonic wave, capacitance level meter, all owing to can not anti-720 ℃ of high temperature and can not satisfy its requirement, and with contactless level gage such as nuclear radiation level gage, then may produce the back that is corroded and leak, thereby exert an influence the operative employee is healthy.
During current electrolysis magnesium is produced, generally be rule of thumb to estimate the liquid level height with the operator, or directly survey is observed in personnel selection, labor strength is very high like this, is unfavorable for healthy.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of liquid level detector for magnesium electrolytic cell, to overcome 720 ℃ of high temperature of not ability of existing in the prior art, maybe may produce corrosion leakage to the healthy deficiency such as exert an influence of operative employee.
Technical scheme of the present invention is: according to the highest liquid level, minimum liquid level position in each electrolyzer, open a hole ￠ 150mm at electrolyzer collection magnesium room cover plate 9 tops, and the flange adapter 3 and the flange 4 of welding respective length, the flange plate 5 of perforate is installed then, cover on the whole in order to insulation with dividing plate 6 again, it is fixing at last the stainless steel bar 1 of 3 unequal lengths to be passed flange plate 5, dividing plate 6 usefulness nuts 7, every stainless steel bar 1 is drawn a lead-in wire 8, lead-in wire 8 inserts a relay circuit, sends into Controlling System by relay tip and carries out sound and light alarm.Wherein, the lower end of a stainless steel bar is concordant with the highest liquid level of setting, and the lower end of another root stainless steel bar is concordant with the minimum liquid level of setting, and the lower end of all the other stainless steel bars is lower than minimum liquid level.
For preventing also to be subjected to corroded area for reducing stainless steel bar because of stainless steel bar produces collision misinformation signal with liquid movement, every stainless steel bar is all outer wears carborudum tube as protective tube 2.
Stainless steel bar 1, protective tube 2 and nut 7, lead-in wire 8 by 3 unequal lengths are formed a post, b post and c post respectively.
Detect principle: when the molten magnesium liquid in electrolyzer collection magnesium chamber during in normal liquid level (between the highest liquid level and minimum liquid level), a post and the not conducting of c post, b post and the conducting of c post; When molten magnesium liquid during in the highest liquid level, a post and the conducting of c post, b post and the conducting of c post; When molten magnesium liquid when minimum liquid level is following, a post and the not conducting of c post, b post and the not conducting of c post.More than three kinds of states send into Controlling System by relay circuit and carry out sound and light alarm, the operative employee can carry out next step operation in view of the above.
Meaning of the present invention and effect are as follows:
The invention solves the molten immeasurable technical barrier of magnesium liquid liquid level in electrolyzer collection magnesium chamber, and simple and easy to do, have very strong operability, can alleviate labor strength, certain guaranteeing role has been played in safety in production.The measuring sensor that the present invention uses all can be made processing or outsourcing by oneself, and is cheap, and entire measuring device is safeguarded simple, and it is convenient to change, and has high cost performance.Similarly working condition is inferior all can prolong usefulness in inconvenient externally fed, high temperature, sealing measuring liquid level etc.

Embodiment
Embodiments of the invention: as shown in drawings, according to the highest liquid level in each electrolyzer, the minimum liquid level position, open a hole ￠ 150 at electrolyzer collection magnesium room cover plate 9 tops, and the flange that welds a respective length takes over 3, in flange adapter 3, weld DN150, the flange 4 of PN1.0, the flange 4 and the steel flange cover plate 5 of perforate, tetrafluoroethylene dividing plate 6 connects, tetrafluoroethylene dividing plate 6 covers 5 of flange plates and goes up in order to insulation, there is screw thread 10 termination, top of stainless steel bar 1,3 stainless steel bars that are uneven in length 1 pass flange plate 5, tetrafluoroethylene dividing plate 6 is fixing by screw thread 10 and nut 7, at steel flange cover plate 5, between tetrafluoroethylene dividing plate 6 and the stainless steel bar 1 silicon carbide protective tube 11 is arranged; Every stainless steel bar 1 is drawn a lead-in wire 8, and lead-in wire 8 inserts a relay circuit, sends into Controlling System by relay tip and carries out sound and light alarm.Wherein, the lower end of a stainless steel bar is concordant with the highest liquid level of setting, and the lower end of another root stainless steel bar is concordant with the minimum liquid level of setting, and the lower end of all the other stainless steel bars is lower than minimum liquid level.
For preventing also to be subjected to corroded area for reducing stainless steel bar because of stainless steel bar produces collision misinformation signal with liquid movement, every stainless steel bar is all outer wears carborudum tube as protective tube 2.
