Abstract
The utility model relates to an anode carbon block with a middle-seam groove, which is characterized in that the middle-seam groove with the width being larger than 20mm is arranged at the bottom of the anode carbon block upwards along the direction of a central line of the length of the anode carbon block so as to replace two narrow grooves opened by the existing and common carbon block. The anode carbon block has the advantages that in the roasting process of the carbon block, not only an exhaust channel can be shortened, the smoke and volatile matters generated in the carbon block are easy to overflow and discharge, the porosity is reduced to lead the roasting in the carbon block to be heated uniformly, the stress is balanced to lead cracks not to be easily generated, and the finished product ratio and the quality of the anode carbon block are improved, but also after roasting, the cleaning of roasting scorched particle in the middle-seam groove is easy, the pollution of the roasting scorched particle to electrolyte and aluminium liquid is reduced in the electrolysis use process of the carbon block, the heat conducting performance is improved, and CO gas in aluminium electrolysis is beneficial to being discharged and precipitated; therefore, the purpose of saving the power consumption for aluminium electrolysis is achieved.
Description
Technical field:
The present invention is a kind of novel aluminum electrolyzing cell used prebaked anode carbon block structure and preparation method.
Background technology:
Existing general anode carbon block for aluminium electrolysis tank has two kinds of structure formations substantially, and a kind of is the anode block of rectangular solid; The shortcoming of this anode block shows two aspects, the one, in the sinter process process, the carbon piece the inner flue gas volatile matter merchant who produces discharge from inside to outside, because the carbon block is long-pending more too, deflated passage (microscopic void) is long more, easily cause the porosity of finished product carbon piece higher, and in the intensification temperature-fall period, carbon piece inside and outside is heated to non-uniform temperature, and the diffusion of thermal stresses and contraction are also inconsistent, it is even also easily to produce carbon piece density unevenness, defectives such as crackle is more, easy fracture; The 2nd, its final product is after being applied to aluminium cell production, because carbon piece bottom surface area is bigger, promptly is unfavorable for the rapid heating of carbon piece, produces the heat conduction non-uniform phenomenon, exists again to be unfavorable for the defectives such as CO gas purging that aluminium electrolysis process is separated out.
Another kind be bottom at anode block along carbon block length direction, be about 110mm apart from the width centreline distance, open about the about 250mm of twice height, the rectangle narrow groove of width about, as shown in Figure 3 less than 15mm.The purpose of opening the narrow groove of these twice be for make anode block in the electrolyzer production process with the CO gas purging with improve electrical efficiency, but two shortcomings that this anode block of opening the narrow groove of twice also exists, the one, the narrow groove of twice is filled the burnt grain of the bonding carbon of absorption in roasting process, because too narrow being difficult to of slit clears up, or cleaning is unclean, after the burnt grain of its carbon is brought in the electrolyzer, influence aluminium liquid and electrolytical quality; The 2nd: for the anode block of whole portion fluting, after the section of anode block was opened the narrow groove of twice, after bottom section was divided into four junior unit sections, the whole end force architecture of its carbon piece was damaged bigger, in roasting process, easily produce brisement, cause the yield rate of carbon piece to reduce.
Summary of the invention:
In order to overcome now general heavy anode carbon piece and on the carbon piece, to open the above-mentioned defective of the anode block existence of the narrow groove of twice, the present invention is on the basis of summing up practical experience, a kind of anode block structure technology scheme with centre joint groove is provided, and the processing method that realizes this structure.
Its technical scheme of anode block of band centre joint groove of the present invention is: in the bottom of anode block upwards, along anode block length centerline direction, open one width centre joint groove greater than 20mm, to substitute the narrow groove of twice that existing general carbon piece is opened.
According to technique scheme; The height of the centre joint groove of being opened in the middle of the anode block bottom makes progress is greater than 120mm.
According to technique scheme, the anode block bottom upwards top of the middle centre joint groove of being opened is a circular arc type.
According to technique scheme, the side elevation of the centre joint groove of being opened in the middle of the anode block bottom makes progress and its section of bottom faces junction of anode block are arc transition.
According to technique scheme, producing of the above-mentioned groove of anode block bottom intermediary can be made in shaping carbon block technology by being installed in carbon piece vibrating forming machine mould, adopts the mechanical cutting method for processing to obtain.
Bottom at anode block makes progress, length direction along anode block, open one width and be the centre joint groove about 20-40mm, its advantage is, at the carbon piece in roasting process, not only can shorten the exhaust-duct, be easy to the inner flue gas volatile matter that produces of carbon piece and overflow discharging, reduce porosity, make the inner roasting thermally equivalent of carbon piece, stress equilibrium, be difficult for cracking, improve anode carbon final product rate and quality, and after roasting, be easy to the cleaning of calcined coke grain in its centre joint groove, reduce the carbon piece in the electrolysis use its calcined coke grain to the pollution of ionogen and aluminium liquid, improve the heat conductivility of carbon piece, be of value in the electrolysis of aluminum CO gas purging and separate out, thereby reach the purpose of joint medicine electrolysis of aluminum power consumption.

Wherein: (1) anode block, (2) centre joint groove, (3) narrow groove
Embodiment:
The present invention is a kind of anode block with centre joint groove, its manufacturing process and existing general heavy anode carbon piece and open twice debt groove anode block manufacturing process basic identical, its difference part is: opening one width in former real core anode block (1) bottom to upper edge carbon piece (1) length direction is more than the 20mm, width is about 35mm, highly be about 250mm centre joint groove (2) as shown in Figure 1 and Figure 2., open the twice width less than the narrow groove of 18mmde (3) to overcome now general fluting carbon piece, burnt grain is difficult to cleaning and opens the twice groove cause carbon piece cracky in the narrow groove so that overcome, the shortcoming that yield rate is lower,
After the anode block of band centre joint groove is used and is produced with aluminium cell, the CO gas purging that its centre joint groove (2) helps in the electrolytic process being produced with overflow, reduce the fluctuation of carbon piece bottom and ionogen contact interface, improve current efficiency.
The anode block that has centre joint groove can be used on the method that one centre joint groove (2) forming tank is installed on the carbon piece vibrating forming machine and makes: also can obtain with the method for mechanical cutting by the anode block after roasting.
