Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Referring to Fig. 1, aluminium electrolysis process temperature of the present invention and aluminium horizontal survey measurement mechanism comprise 8-12 temperature-sensitive node 3, and temperature-sensitive node is along arranged in a straight line, and the spacing of adjacent temperature-sensitive node 3 is 0.8cm-1.2cm, when use, these temperature-sensitive nodes 3 can lay respectively in electrolyte and aluminium liquid. For the ease of regulating height, sensor is also provided with adjustable support bar 5, and support bar 5 is highly 30cm-50cm.
Preferably temperature-sensitive node is thermocouple, temperature-sensitive node 3 is the binding site of thermocouple wire 2, thermocouple wire 1 is drawn and is received data acquisition unit (not shown) by going between, in thermocouple wire outside, cover has stainless steel sleeve pipe 4, support bar 5 setting perpendicular to the ground, and be fixedly connected with sleeve pipe 4 at an angle with one end (not containing one end of temperature-sensitive node) of sleeve pipe 4.
Measuring process comprises: the first step, according to the seat of the good support bar 5 of conventional aluminium Level tune, also determined the height of each temperature-sensitive node simultaneously; Second step, puts into electrolytic cell by sensor, until support bar 5 contacts with ground, ensures that multiple temperature-sensitive nodes 3 are distributed in aluminium liquid and electrolyte; The 3rd step, opens data acquisition unit switch, starts to measure, and maintains 15-25 second; The 4th step, takes out sensor, and instrument records electrolyte temperature, temperature of aluminum liquid and aluminium horizontal data automatically. Wherein, the measurement of temperature adopts thermocouple directly to obtain, and the measurement of aluminium level is different according to the heat transfer property of electrolyte and aluminium liquid, and heating rate and equilibrium temperature are not identical. By calculating the heating rate of each temperature-sensitive node, calculating each point reaches the time of equilibrium temperature, judge the position of each node, find out heating rate and equilibrium temperature and differ maximum adjacent node, using the centre position (also can select other positions between these two adjacent nodes according to the trend of variations in temperature) of these two adjacent nodes as the position of aluminium liquid and electrolyte interface, finally according to the height at this interface of high computational of interface location and adjusting support bar, i.e. aluminium level.
