Furthermore, the exhaust vent is a through-hole, which can be a vertical through-hole or an oblique through-hole having a certain angle with the vertical line, the exhaust hole further can be a semi-through hole which is not communicated to a bottom palm, the distance between the bottom of the semi-through hole and the bottom palm is 1-30 mm, and a high-temperature resistant and oxidation-resistant nonmetallic pipeline or metallic pipeline is arranged above the exhaust vent. The anode has the advantages that the problem of remaining air bubbles of the bottom palm of the anode is effectively salved, the air bubbles under the anode bottom palm are smoothly discharged, the resistance of a slot is reduced, the generation of effect is prevented, the set voltage and the working voltage of an electrolytic tank are reduced, thereby realizing reducing the electrical consumption. When one ton of aluminum ingot is produced, 60-150 kilowatt-hours of electricity can be saved.
Description
Technical field:
The utility model relates to the improvement of the anode block interior shape structure of used for aluminium electrolysis.
Background technology:
In Aluminium Electrolysis technology, the function of anode block is: direct current energy is transferred to the electrolyte solution in the electrolyzer by anode rod, explode piece, anode steel jaw and anode block, thereby realizes aluminum electrolysis technology production.
The anode that the aluminum current electrolysis is used is imitative rectangular parallelepiped piece, and upper surface is embedded with steel pawl electric installation, and bottom is planar design.In the Aluminium Electrolysis technological process, produce a large amount of CO below the carbon anode bottom
2Gas, these gases very easily mix and are stored in the ionogen, because anode bottom area is big and flat, the gas come-up meets obstructions, and are difficult to smoothly that come-up is contrary to be gone out outside the groove.And anode bottom bubble can not in time be discharged, and along with the time changes, small bubbles are accumulated into air pocket.When most of anode bottom formed large-area bubble down, electrolyzer resistance sharply increased, thereby forms anode effect.Even do not form anode effect, cell resistance also can increase many, thereby causes bath voltage to raise, and power consumption increases.Common CO
2Can produce the volts lost of 250mV, and volts lost meeting power consumption 3 degree of 1mV are produced 1 ton of aluminium ingot like this and can be consumed 750 degree more.
Summary of the invention:
The purpose of this utility model is to provide a kind of anode with gas exhausting hole for aluminum electrolysis, and its use can effectively solve the bubble retention problems that the anode bottom gathers.
The purpose of this utility model realizes by following scheme: anode with gas exhausting hole for aluminum electrolysis is characterized in that: anode block inside is provided with venting hole.
The purpose of this utility model also can further realize by following scheme:
Venting hole can be through hole; When adopting through hole, can be vertical through holes, also can be the oblique through hole angled with vertical line.
The cross section of venting hole is the identical or different cylindrical hole of geometrical dimension; Or the cross section of venting hole is one of shapes such as ellipse, trilateral, rectangle, Polygons.
Venting hole can be obstructed half through hole to bottom, and the bottom of half through hole is 1～30 centimetre apart from the bottom of bottom.
Above venting hole, be provided with high temperature resistant anti-oxidation nonmetal pipeline or metallic conduit.
Venting hole is 1～6.
The aperture of venting hole is 0.3～10 centimetre.
Advantage of the present utility model is: can effectively solve the bubble retention problems that the anode bottom gathers, make outside the smooth drain tank of bubble under the anode bottom, reduce cell resistance, avoid effect to take place, reduce electrolyzer setting voltage and operating voltage, thereby realize reducing power consumption.Produce 1 ton of aluminium ingot, 60～150 degree can economize on electricity.
Description of drawings:
Fig. 1 is the utility model structural representation, and Fig. 2 is another structural representation of the utility model.
Embodiment:
Below in conjunction with embodiment, the utility model is done further narration.
Embodiment 1: as shown in Figure 1, anode carbon block 1 is a tetragonal body, its bottom surface 2 is the plane, end face is embedded with steel pawl 3, steel pawl top is provided with blast piece 4 and guide rod 5, produces vertical cylindrical air exhaust hole 6 at anode block near the position at center, and the aperture of venting hole can be selected 0.3～10 centimetre, preferable range is 1～7 centimetre, and the best is 5～6 centimetres; Venting hole can be chosen as through hole, can be vertical through holes, also can be the oblique through hole that has a certain degree with vertical line; Venting hole is obstructed half through hole to bottom, and the bottom of half through hole is 1～10 centimetre apart from the bottom of bottom.The cross section of venting hole can be the identical or different cylindrical hole of geometrical dimension; Can be one of shapes such as ellipse, trilateral, rectangle, Polygons also, or be the combination of two kinds and several shapes.Venting hole can be selected 1～6, is preferably 1～2.For anti-oxidation, it is close with the venting hole diameter to place a bottom on venting hole, the stopper that upper diameter is bigger, the suitable for reading of venting hole blocked, afterwards, on the end face of anode block, stack the face-piece mulch of 10～20 centimetres of thickness again, again stopper is removed afterwards, mulch has formed up big and down small funnel-form above venting hole like this, thereby avoids mulch to fall to stopping up venting hole.
Wash away down in electrolytical rotation behind the groove on this anode, the venting hole that stretches in the ionogen will form depression hole shape on every side, thereby make the bubble under the anode bottom accumulate in the pit earlier and very fast discharge up.Solved the anode effect that bubble under the anode bottom gathers formation effectively, electrolyzer resistance is reduced and kept steady state.Reach and reduce the groove operating voltage, thereby reach the purpose that reduces power consumption.
Embodiment 2: as shown in Figure 2, because heap has the face-piece mulch of 10～20 centimetres of thickness above the anode, stop up in order to prevent that mulch from falling into to produce in the venting hole, be provided with a placement hole 61 on the top of venting hole, in placement hole, be placed with high temperature resistant anti-oxidation nonmetal pipeline (or metallic conduit) 7, thereby form the air flue, and then around pipeline, add face-piece fragment mulch.Pipeline can form with aluminum oxide adding additives compacting, with after remake alumina raw material and drop into use in the electrolyzer.The also available carbon materials of pipeline is made, and also available other material is made.
In the utility model, venting hole can be through hole up and down, for ease of the once shaped manufacturing, also can be last logical half obstructed through hole down, when adopting half through hole, but the bottom of venting hole is 1～30 centimetre apart from the bottom face, preferable range is 1～10 centimetre, optimum range is 1～5 centimetre, owing at the anode block on period loss can take place, positive piece bottom was about 4～6 centimetres of losses in 3～4 days, therefore, when adopting the optimum range design, half through hole got final product conducting later at 3～4 days, became real venting hole.
What deserves to be mentioned is that the thief hole of half through hole of the present utility model and manufacturing and use producer check usefulness is inequality, about 20 centimetres of the general degree of depth of thief hole, the general degree of depth of half through hole of this programme is greater than 40 centimetres.And thief hole selects 1% to inspect by random samples usually during check, and half through hole of the present utility model makes on each anode block.
When making the anode block of band venting hole, the drilling rod is set below normally used top cover, the drilling rod is inserted in the anode block raw material through the moulding of vibration pressing one-time, thereby form the anode block of band venting hole.
Anode block described in the utility model can be a carbon piece anode, also can be inert anode, can also be the anode that other material is made.
