Description
Technical field
The utility model relates to a kind of metering facility, especially a kind of anodic current measurement bay.
Background technology
At present, in the prebaked cell production process, the measurement that anodic current distributes is the most often carried out in the domestic electrolysis of aluminum industry, and must carry out full electrode current distribution measuring every day, employing be the manual measurement method of off-line equidistance volts lost.Existence can not be eliminated the influence that the current measurement of anode rod temperature variation antianode brings, and produces measuring error; Because manual measurement can only be measured an anode at every turn, carry out next anodic after having operated again and measure, process of measurement is complicated, and workload is big, and the time is long.Therefore, the measuring result lifetime is poor, can not truly reflect the distribution situation of anode electrolytic cell electric current; Measuring result can not be sent into computer control system in real time, need submit the related personnel to measuring the result, and be input to computer system by rules.If do not overcome the above problems, anodic current is measured and can't be produced a desired effect, and can't true reappearance anode electrolytic cell distribution of current situation and variation tendency, finally influences the production of whole electrolyzer.
The utility model content
The utility model provides a kind of accuracy of detection height, can carry out temperature compensation anodic current measurement bay.
Realize the anodic current measurement bay of the utility model purpose, comprise U type card frame, be fixed on the backing plate on said U type card frame right side, said backing plate right side is provided with probe support, and said probe support is fixed on the U type card frame; The left side of said U type card frame is provided with push rod, and the left end of said push rod is provided with handwheel, and said handwheel can promote push rod and move; Said probe support is provided with two measuring probes, is provided with spring between said measuring probe and the probe support, make measuring probe relatively probe support do stretching motion; Said backing plate is provided with the electronic temperature sensing device.
Described anodic current measurement bay also comprises the signals collecting transmitter, is used to gather the signal of measuring probe and electronic temperature sensing device, and converts the anodic current signal into, sends into system through the mode of wireless transmission.
The beneficial effect of the anodic current measurement bay of the utility model is following:
The anodic current measurement bay of the utility model; Can detect anodic current in real time; And detecting the temperature of anode rod simultaneously, the antianode electric current is realized temperature compensation, eliminates the influence that the current measurement of anode rod temperature variation antianode brings; Through Wireless transmission mode measuring result is sent to computer control system, truly reflects the distribution situation of anode electrolytic cell electric current; This production is simple in addition simultaneously, has temperature compensation function, therefore has the high and continuous detecting function of accuracy of detection, does not need other power-equipments auxiliary, free from environmental pollution, environmental protection and energy saving.
Description of drawings
Fig. 1 is the structural representation of the anodic current measurement bay of the utility model.
Embodiment
As shown in Figure 1, the anodic current measurement bay of the utility model comprises U type card frame 2, is fixed on the backing plate 3 on said U type card frame 2 right sides, and said backing plate 3 right sides are provided with probe support 1, and said probe support 1 is fixed on the U type card frame 2; The left side of said U type card frame 2 is provided with push rod 5, and the left end of said push rod 5 is provided with handwheel, and said handwheel can promote push rod 5 and move; Said probe support 1 is provided with two measuring probes 6, is provided with spring 7 between said measuring probe 6 and the probe support 1, make measuring probe 6 relatively probe support 1 do stretching motion; Said backing plate 3 is provided with electronic temperature sensing device 4.
Described anodic current measurement bay also comprises the signals collecting transmitter, is used to gather the signal of measuring probe 6 and electronic temperature sensing device 4, and converts the anodic current signal into, sends into system through the mode of wireless transmission.
The principle of work of the anodic current measurement bay of the utility model is following:
Entire measuring device is fixed on the anode rod through push rod 5.In the fixation procedure, along with the precession of push rod 5, the continuous direction indentation of measuring probe 6 meetings to probe support 1; Again because the effect of spring 7 is arranged; Measuring probe 6 can remain in the good contact of anode rod all the time, till this process can last till backing plate 3 and anode rod closely contacts, guarantees that two structure physical efficiencys closely contact with anode rod simultaneously; Both guaranteed that backing plate 3 closely contacted with anode rod, guaranteed also that measuring probe 6 contacted with the tight of anode rod simultaneously.We know according to Ohm's law, and the electric current through one section conductor equals voltage on this section conductor divided by the resistance of this section conductor; The resistance of one section conductor is relevant with xsect, length, the resistivity of this section conductor, and resistivity is not only relevant with the material character of conductor, and is also relevant with the height of temperature; Because the sectional area known constant of anode rod is constant, the spacing of two probes is certain, measurement be equidistance voltage; The resistivity of anode rod is also known; Therefore, as long as record the voltage of a determining deviation on the guide rod and the temperature on this section guide rod, just can obtain the electric current of anode rod.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineering technical personnel in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
