Abstract
The utility model discloses a cathode carbon block group heater. A thermal resistor (4) is arranged on a heat insulation cover (6), electric heating elements (5) are arranged in the heat insulation cover (6), a heat insulation base (7) is arranged at the bottom of the heat insulation cover (6), a cathode carbon block and a steel bar are fixed on the heat insulation base (7), the electric heating elements (5) are arranged on the top face and two lateral faces of the heat insulation cover (6), and a positioning inclined face used for placing the cathode carbon block and a positioning inclined face used for placing the heat insulation cover are arranged on the heat insulation base (7). The cathode carbon block group heater can reach requirement on the heating temperature of the combined cathode carbon block and the steel bar, and has the advantages of small temperature difference and convenience for taking out.
Description
Technical field
The utility model relates to a kind of bottom of electrolytic tank with cathode carbon pieces group heating unit.
Background technology
The heating of cathode carbon pieces group mainly is that cathode blocks and rod iron carry out combined heated, and purpose is with carrying out ferrophosphorus casting (bonding) after cathode carbon pieces and the rod iron heating.
How the bonding of cathode carbon pieces and rod iron combination sticks with paste with pricking, and this form is simple, but big, the easy heating of resistance, electroconductibility is general.
Cathode carbon pieces and rod iron adherent quality are used most important to electrolyzer.Ferrophosphorus cast this form be casting evenly, little, the good conductivity of resistance.The ferrophosphorus this form of casting is a lot: adopt the form (test) of digging pit such as the producer that has, and placement wire spiral or electrothermal tube in the hole, the top takes the cover plate cathode blocks and rod iron carries out combined heated, carries out ferrophosphorus after the heating and casts, and effect is undesirable; The producer that has adopts heats the energising of rod iron two, and what rod iron produced is heat passage to cathode carbon pieces concave surface place.All undesirable from above-mentioned two kinds of form effects.Major cause is that the charcoal piece is easy to crack, and the temperature heating is irregular, not enough, causes the temperature difference big (temperature ~ 1100-1200 of ferrophosphorus ℃).
Cathode carbon pieces and rod iron are two kinds of material different: cathode carbon pieces is mainly formed (proportion ~ 1.6) by coke powder, grain and a small amount of pitch, and the rod iron material is Q215-A structural carbon steel (proportion 7.85).The charcoal piece to certain temperature to burn, so such combination has brought difficulty to heating.Therefore need that a kind of Heating temperature of research can meet the requirements of, the temperature difference is less and convenient new type heater structure of taking out.
Summary of the invention
The purpose of the utility model is: a kind of cathode carbon pieces group well heater is provided; This well heater cathode blocks and rod iron combined heated temperature can reach requirement, the temperature difference is less and convenient taking-up; Easy to crack to overcome the charcoal piece that prior art exists; The temperature heating is irregular, not enough, causes the bigger deficiency that waits of the temperature difference.
The utility model adopts following technical scheme: stay-warm case is provided with hot resistance, and an electric heating element is installed in the stay-warm case, is provided with band insulation base in the bottom, and cathode carbon pieces and rod iron are fixed on above the band insulation base.
An electric heating element is installed in end face and two sides in the stay-warm case.
On band insulation base, be provided with the inclined-plane, location of laying cathode carbon pieces and the inclined-plane, location of laying stay-warm case.
Each root tubular type an electric heating element power that the utility model is installed is 9kW (totally 30), total power 30 * 9=270 kW.In order to satisfy 3 ~ 5 hours heat-up times, 550 ~ 600 ℃ of Heating temperatures, prevent the charcoal piece cracking phenomena that the temperature difference is brought, strengthened power (former power is 120 ~ 150 kW), the power adjustment is adopted as electrodeless.
Compared with prior art, the utility model cathode blocks and rod iron combined heated temperature can reach requirement, have the advantage of the less and convenient taking-up of the temperature difference.

Embodiment:
The embodiment of the utility model: like Fig. 3,4 signals, stay-warm case 6 is provided with hot resistance 4, and an electric heating element 5 is installed in the stay-warm case 6, is provided with band insulation base 7 in the bottom, and cathode carbon pieces and rod iron are fixed on above the band insulation base 7.
An electric heating element 5 is installed in end face and two sides in the stay-warm case 6.
On band insulation base 7, be provided with the inclined-plane, location of laying cathode carbon pieces and lay the inclined-plane, location of stay-warm case, so that can locate preferably when laying.
An electric heating element 5 is the tubular type an electric heating element, and its shape is seen Fig. 5, Fig. 6.
Hot face is end face and two sides, totally 3 faces.An electric heating element 5 is installed in stay-warm case 6 bodies.The heating of cathode carbon pieces and rod iron group is heated in whole airtight thermal insulator, and top is provided with venting port.
Cathode carbon pieces and rod iron group differ 180 ° in the position of stay-warm case 6 intravital installation sites and accompanying drawing 1.
After heating reaches requirement, stay-warm case is hung out, then carry out the ferrophosphorus casting.Intact back is held cathode carbon pieces and the rod iron group that it is good to cast in the cathode carbon pieces bottom with special tool and is hung out, and carries out the heating and the pouring operation of next group then.
