Abstract
The utility model provides a prebaked specially-shaped anode steel claw for electrolyzing aluminum. The prebaked specially-shaped anode steel claw for electrolyzing aluminum mainly comprises an aluminum guiding rod (1), a steel claw (2) and an anode carbon bowl, wherein the steel claw is provided with a steel claw main plate (21) and claw teeth (22); the steel claw main plate (21) is arranged at one end of the aluminum guiding rod (1); some of the steel claw teeth (22) are immersed in the anode carbon bowl; and at least one hole or slot is formed in the contact surface of the steel claw teeth (22) and the anode carbon bowl. By adopting the anode steel claw with the structure, the contact tightness of the bottom of the steel claw and the bottom of the carbon bowl is improved, so that the electrical conductivity of the anode steel claw is improved, the electricity consumption for electrolyzing aluminum is lowered, and thus the energy consumption and the cost for electrolyzing aluminum are lowered.
Description
Technical field
The utility model relates to a kind of prebake electrolytic aluminium anode steel pawl, relates in particular to a kind of prebake electrolgtic aluminium abnormity anode steel jaw.
Background technology
It is little that prebaked cell has pollution; Advantage of low energy consumption has replaced the major equipment that soderberg cell becomes aluminum electrolysis industry at present; And the capacity of electrolyzer is increasing, and the main aluminium guide bar of alternate anode device, steel pawl, anode carbon block are formed, and are bearing galvanic conducting function.
But receive the restriction of each tie point/face closeness of contact; Domestic aluminum electrolysis industry anode voltage is high; Directly affect the energy consumption and the production cost of Aluminum Electrolysis Production,, reduce the pursuit that the anodic contact drop becomes the aluminum electrolysis industry numerous enterprises in today that country advocates energy-conservation production energetically.
Steel pawl structure subject matter is in the prior art: it is bad that (1) steel pawl bottom and carbon bowl bottom contact effect; There is the gap of size between 0.1-15mm; Cause carbon bowl bottom-phosphorus pig iron through the contraction owing to the phosphorus pig iron after the cast of the phosphorus pig iron; There is the gap in steel pawl bottom-phosphorus pig iron contact surface, and then has caused the reduction of whole anode assembly conductivity, has caused the rising of electrolytic aluminum power consumption; (2) the existing cylindrical shape of ordinary steel pawl side surface, under the long-pending certain condition of steel-claw body, when the bottom surface was rounded, girth was the shortest, and lateral area is minimum, and contact area is minimum, so conductive area is minimum, and conductivity is the poorest.
Therefore, how long-pending constant at steel-claw body, under the profile situation that great changes will take place, improve steel pawl bottom and the contact area that contacts tightness degree and increase steel pawl side surface and carbon bowl of carbon bowl bottom and be those skilled in the art and want the technical problem that solves always.
Summary of the invention
The purpose of the utility model is to provide a kind of prebake electrolgtic aluminium abnormity anode steel jaw that can overcome above-mentioned defective; It does improvement in shape by inner bottom part and immersion anode carbon bowl excircle partly at original anode steel jaw, thereby has realized the contact area that contact tightness degree and increase steel pawl side surface and anode carbon bowl of raising steel pawl bottom with the anode carbon bowl bottom.
Concrete, to achieve these goals, the described prebake electrolgtic aluminium abnormity of the utility model anode steel jaw includes aluminium guide bar, steel pawl and anode carbon bowl; Said; The steel pawl has steel pawl mainboard and blade tooth, and steel pawl mainboard is arranged at an end of aluminium guide bar, and the part of steel pawl blade tooth immerses the anode carbon bowl simultaneously; And the contact surface of described steel pawl blade tooth and anode carbon bowl has all been dug at least one hole or groove.Wherein, Each blade tooth of the described steel pawl of the utility model and anode carbon bowl contact surface have all been dug at least one hole or groove, and said hole or groove can be circle, rectangle or irregularly shaped, and the size of hole or groove and number are confirmed by the size of anode steel jaw; Cutting through above groove, hole; Realized the ordinary steel pawl by the transformation of flat bottom, and realized the contact tightness degree of raising steel pawl bottom, thereby improved conductivity with the carbon bowl bottom to special-shaped bottom surface.In addition; The excircle that the utility model steel pawl blade tooth immerses anode carbon bowl part is provided with decorative pattern, and said decorative pattern can be processed as shapes such as plum blossom, spiral, striped, thereby has increased the surperficial contact area of steel pawl and anode carbon bowl; And then increased conductive area, improved conductivity.
Can know in sum; Adopted the prebake electrolgtic aluminium abnormity anode steel jaw of said structure; Owing to improving the contact tightness degree of steel pawl bottom, increased the surperficial contact area of steel pawl and anode carbon bowl, thereby improved the conductivity of anode steel jaw with the carbon bowl bottom; And then realize to reduce the power consumption of electrolytic aluminum, finally reduce the energy consumption and the cost of electrolytic aluminum.

Embodiment
In order better to understand the purpose of the utility model, characteristic and function are described in detail the structure and the function of two specific embodiments of the utility model below in conjunction with accompanying drawing.
Can know that by Fig. 1 a, Fig. 1 b and Fig. 1 c common steel pawl includes aluminium guide bar 1, steel pawl 2, and anode carbon bowl (not shown); The steel pawl is made up of steel pawl mainboard 21 and blade tooth 22, and wherein steel pawl mainboard 21 is simple strip, and blade tooth 22 is simple cylindrical-shaped structure; The blade tooth part that immerses the anode carbon bowl is simple periphery too, and improves later steel pawl structure, can be found out by Fig. 2 a, 2b and 2c; It equally also includes aluminium guide bar 1 and steel pawl 2, and the steel pawl is made up of steel pawl mainboard 21 and blade tooth 22, and different is; Fig. 2 a, 2b and Fig. 3 can find out, improve later steel pawl structure, promptly; The contact surface 23 that the blade tooth of the described steel pawl of present embodiment contacts with the anode carbon bowl bottom offers at least one hole or groove, and in the present embodiment, this contact surface place offers a circular port 24 and a rectangular opening 25; And number and the shape of offering hole or groove need decide according to the size of anode steel jaw blade tooth 22, not other special limitation; Can offer a circular hole, also can offer a rectangular opening, can also not only offer circular hole but also offer rectangular opening; Also can offer hole or groove into other shapes, for example circle, rectangle, square, trapezoidal or other are irregularly shaped, said hole or groove can be these shapes; But be not limited to these shapes, other shapes that can play same function are all passable, and offering of these holes improved the closeness of contact of steel pawl bottom with the anode carbon bowl bottom.In addition; Can also know by Fig. 2 a, 2b and Fig. 3; Said steel pawl immerses and also is provided with decorative pattern 26 on the excircle of part of anode carbon bowl increasing the contact area with the anode carbon bowl, and said decorative pattern 26 can be that screw thread or plum blossom shape or other can play the decorative pattern of identical increase contact area arbitrarily, in the described embodiment of the utility model; Like Fig. 2 a, 2b, 2c and shown in Figure 3, said decorative pattern is a plum blossom shape pattern.
