The grooves are formed in all the side faces of the anode body. The top face comprises a chamfer which is obliquely connected with the side face; an upper end fracture on each groove is arranged on the chamfer. The bottom face and all the side faces of the anode body are connected vertically. The anode for the aluminum electrolysis has an air exhausting function and the grooves can be molded integrally when the anode is molded, so that the structural strength is high.
Description
Technical field
The utility model relates to a kind of anodes used in aluminum electrolysis.
Background technology
In the process of aluminum production by fused-salt electrolysis, anode is to make with carbon materials at present, and it not only conducts electricity, and participates in redox reaction, and during electrolysis, anodic oxidation generates CO
2, simultaneous oxidation aluminium is reduced to metallic aluminium.The CO generated
2Be a kind of oxidizing gas, can generate CO with the C secondary reaction, cause the extra consumption of anode.So CO
2Discharge extremely important, CO
2Discharge and not only can accelerate to generate the reaction of metallic aluminium from electrolyzer fast, improve current efficiency, can also reduce the extra consumption of anode, otherwise will bring degradation problem under the increase of anode air film resistance, anode consumption increase, current efficiency.
In prior art, a kind of structure of anodes used in aluminum electrolysis as depicted in figs. 1 and 2, comprise anode body 90 and exhaust-duct, anode body 90 is rectangular parallelepiped, side with end face, bottom surface and surrounding, exhaust-duct comprises the horizontal through hole 92 communicated with described blind hole 91 arranged in the blind hole that extends to along the vertical direction anode top 91 that arranges on bottom surface and top, the gas that anodic reaction produces enters blind hole 91 from the anode bottom, finally by horizontal through hole 92, is discharged.The another kind of structure of prior art Anodic as shown in Figure 3 and Figure 4, exhaust-duct is that the groove 93 of anode laterally or is vertically run through on the edge in the horizontal direction that is arranged on bottom, groove 93 degree of depth are less than the height of anode, the gas that anodic reaction produces enters groove 93 from the anode bottom, finally by the lateral openings of groove 93, is discharged.But, because the anode material is special, above-mentioned blind hole 91, horizontal through hole 92 and groove 93 need anode in corresponding die for molding, after the roasting kiln roasting, adopt again mach mode to process, so not only caused the decline of anode construction intensity, and difficultly during the lower material recycling of cutting after machining by pitch, infiltrated, strengthened selective oxidation reaction when on the anode, groove is used, and groove 93 can increase anode and O
2, CO
2Contact surface, aggravated the extra consumption of anode and fallen slag.The problems referred to above are in the situation that continuous increase, the anode dimension of aluminium cell capacity are increasing more outstanding.
The utility model content
The purpose of this utility model is to provide a kind of have degassing function and the high anodes used in aluminum electrolysis of structural strength.
The technical solution adopted in the utility model is: a kind of anodes used in aluminum electrolysis, comprise there is end face, the anode body of the side of bottom surface and surrounding, offer length direction on the side of described anode body and extend along the vertical direction and connect the end face of anode body and the groove of bottom surface, described groove is semicircle perpendicular to the cross section of length bearing of trend.
Be provided with groove on each side of described anode body.
Described end face comprises and the laterally inclined fillet surface be connected, and the upper end fracture of described groove is arranged on fillet surface.
The Yu Ge side, bottom surface of described anode body is vertical connection.
The utility model adopts technique scheme, offering length direction on the side of anode body extends along the vertical direction and connects the end face of anode body and the groove of bottom surface, can discharge for anodic gas in use, there is degassing function, and groove is semicircle perpendicular to the cross section of length bearing of trend, be convenient to the demoulding when using mould molding, can be when the anode moulding integrated molding, prevent from by machining, the impact that exhaust-duct antianode intensity is brought being set again after anode shaped, and, said structure is the corner angle at notch edge gently, thereby reduce the slag that falls of anode.
