Abstract
The utility model discloses a cathode steel bar connecting plate structure of an electrolytic bath. L-shaped connecting plates (1) are adopted, the L-shaped connecting plates (1) connect cathode steel bars (2) and steel-aluminum explosion welding blocks (3) through welding seams (4), the L-shaped connecting plates are located on the inner sides of the cathode steel bars (2) or on the outer sides of the cathode steel bars (2), a connecting plate in a 'concave' shape or a connecting plate in a 'protrusion' shape is composed of two L-shaped connecting plates (1), and the connecting plate in the 'concave' shape or the connecting plate in the 'protrusion' shape, which is composed of the two L-shaped connecting plates (1), is connected with two cathode steel bars (2) simultaneously. The L-shaped connecting plates are welded with end faces and sides of the cathode steel bars, the welding seams are lengthened, and the welding contact area is increased, so that the cathode drop of the electrolytic bath is reduced.
Description
Technical field
The utility model relates to a kind of member connection structure of aluminum cell cathode steel bar head.
Background technology
Electrolytic cell cathode steel bar with welding and crimping dual mode are generally arranged being connected of the soft band of negative electrode, wherein the crimping mode is taked in recent years design substantially, but domestic and international early stage large-sized prebaked electrolyzer all adopts welding process.Compare with the crimping form, be connected by the mode of web plate welded cathode rod iron with the blast welding block, the characteristics such as it has good connecting effect, pressure drop is low, the heating power consumption is low, economize on electricity.
On the electrolyzer of existing operation, web plate is generally rectangle, a side and the welding of cathode steel bar end face, and opposite side is connected the purpose of switching on the explosive welding block welding to reach.The web plate of rectangular configuration exists the area that is welded to connect little, connects the not firm deficiency that waits.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of aluminum cell cathode steel bar connecting board structure is provided, and is little to overcome the area that rectangular configuration web plate that prior art exists is welded to connect, connect not firm wait not enough.
The technical solution of the utility model is as follows: adopt " L " shape web plate, " L " shape web plate is connected cathode steel bar by welded seam with steel-aluminum explosive weld block.
" L " shape web plate is positioned over the medial surface of cathode steel bar, perhaps is placed on the outer side of cathode steel bar.
" L " shape welding edge bevelling of " L " shape web plate and cathode steel bar weld, the welding edge bevelling of " L " shape web plate and steel-aluminum explosive weld block.
Two " L " shape web plates connect respectively two cathode steel bars simultaneously.
Two " L " shape web plates consist of the web plate of " recessed " shape structure, perhaps consist of the web plate of " protruding " shape structure.
The web plate of " recessed " shape structure that is comprised of " L " shape web plate or the web plate of " protruding " shape structure connect two cathode steel bars simultaneously.
The utility model adopts the i.e. web plate of abnormal shape of " L " shape web plate.Web plate by with the welding of cathode steel bar end face and side, increase soldered, increase the welding contact area, to reach the purpose that reduces the electric tank cathode pressure drop.
