CN205241803U - Negative pole rod iron that adoption golden section is ordered - Google Patents

Abstract

The utility model provides a 1.2 -1.5 doubly that negative pole rod iron that adoption golden section is ordered opens the seam in the golden section of rod iron height point 0.618H position, and straight joint length extension is for the tradition length of cracking. The utility model discloses to crack the position shifts up the point to golden section from the middle part, can raise the position of blocking horizontal electric current in the electrolysis trough production process, the length of will cracking is extending, can increase the scope of blocking horizontal electric current. Through optimizing this two technology measures, can effectively cut off the electrolysis trough horizontal electric current in when production, reduce reactive loss, reduce unreasonable calorific capacity, energy saving in the production process, save the cost, reduce CO2's emission.

Description

Adopt the cathode steel bar of golden section point

Technical field:

The utility model belongs to a kind of construction and life of aluminum electrolysis industry all size aluminium cellProduct equipment, particularly a kind of cathode steel bar that adopts golden section point.

Background technology:

Aluminium cell is a kind of production equipment of high energy consumption, and when production, electric current is generally tens of Wan AnTraining. At present in industry, take to optimize Insulation, the multiple joints such as technique crack on cathode steel barEnergy measure, the technique electrolytic cell horizontal current capable of blocking density of wherein cracking on cathode steel bar,Improve current efficiency, but interior general the cracking and (see attached along cathode steel bar height middle part of industry at presentFig. 1,2,3) technique have certain defect, current efficiency improve not obvious, reactive currentStill larger.

Summary of the invention

The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art, and carriesFor a kind of cathode steel bar that adopts golden section point, this rod iron is by cracking on optimized cathode rod ironPosition, effectively solve aluminum current electrolytic cell produce in overstocked, the reactive loss mistake of horizontal currentLarge problem.

As above design, the technical solution of the utility model is: a kind of the moon that adopts golden section pointUtmost point rod iron, is characterized in that: seam is opened in the golden section point 0.618H position at rod iron height.

The 1.2-1.5 that above-mentioned straight joint length is traditional cracking length doubly.

The utility model is along cathode steel bar short transverse golden section point 0.618H position, millingGo out a straight joint, the position of cracking moves to golden section point from middle part, electrolytic cell can be producedTime blocking-up Current Position raise, eliminate and form the condition of horizontal current, effectively cut off electrolytic cellHorizontal current when production, reduces reactive loss, saves the energy, saves cost. And owing to fallingLow reactive loss, has correspondingly also reduced the unreasonable caloric value in production process, energy-conservationWhen consumption reduction, operation stability and the service life that can obviously improve electrolytic cell.

Brief description of the drawings:

Fig. 1 is aluminium electrolytic cell cathode schematic diagram;

Fig. 2 is the top view of Fig. 1;

Fig. 3 is the conventional cathode rod iron schematic diagram that cracks;

Fig. 4 is the utility model schematic diagram.

In figure: 1-cathode carbon pieces; 2-rod iron is stuck with paste; 3-cathode steel bar; 4-rod iron cracks; 5-Cathode steel bar part is done and is insulated; The straight joint that 6-golden section point 0.618H position mills out.

Detailed description of the invention:

As shown in Figure 3: a kind of cathode steel bar that adopts golden section point, along cathode steel bar heightDirection golden section point 0.618H position, mills out a straight joint 6, and this straight joint length lengthens and isThe 1.2-1.5 of tradition cracking length doubly.

The utility model position of cracking moves to golden section point from middle part, can raise electrolysisIn groove production process, block the position of horizontal current; Cracking length, lengthening, can be strengthened to resistanceThe scope of disconnected horizontal current. By optimizing this two technological measures, can effectively cut off electrolytic cellHorizontal current when production, reduce reactive loss, reduce unreasonable caloric value in production process,Save the energy, save cost, reduce CO₂Discharge capacity.

In the time that rod iron is assembled, must be noted that the direction of rod iron, should make 0.618H be on heightWide top, must not be anti-loaded towards charcoal piece side.

The utility model is actual use on the aluminium cell of plurality of specifications, more traditional work of crackingSkill has obvious energy-saving effect, can reach and improve current efficiency 0.5%, ton aluminium production economize on electricityThe level of 220kwh.
