Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cells, in particular to an anode current increasing device at a corner of an electrolytic cell. Background Art

[0002] The problem of enlarged legs at the corners of aluminum electrolytic cells affects the stability of the operation of the electrolytic cells, resulting in the non-consumption of electrolytic cell anodes and reduced current efficiency of the electrolytic cells. When the corners are enlarged, the anode guide rods will be damaged, causing damage to the hoist. This is a common negative phenomenon in the production process of electrolytic aluminum. In order to gradually melt the large legs and improve the operation of the electrolytic cell, it is necessary to reduce the total pressure drop of the anode system at the corners of the electrolytic cell and increase its conductivity. In this regard, the utility model provides an electrolytic cell corner anode current increasing device to solve this technical problem. Utility Model Content

[0008] Furthermore, the clamping plate is circular and a convex body is arranged at the center of the clamping plate, and a groove body is arranged on the docking plate, and the groove body extends into the convex body.

[0009] Furthermore, the bracket is welded from three pieces of channel steel, and the bracket spans the horizontal busbar and the anode guide rod.

[0010] Furthermore, the butt joint plate is two 150mm*130mm*20mm aluminum plates welded into an "L" shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model sets a butt joint plate at the right angle between the horizontal busbar and the anode guide rod, thereby increasing the contact area between the horizontal busbar and the anode guide rod, achieving the purpose of reducing the voltage drop, increasing the anode current intensity at the corner, and gradually melting the large extension leg. The butt joint plate is clamped by a clamping mechanism to facilitate the later pole replacement and removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

The docking plates 3 are arranged on both sides of the anode guide rod 2 and the docking plates 3 are in contact with the horizontal busbar 1 and the anode guide rod 2, thereby increasing the contact area between the horizontal busbar 1 and the anode guide rod 2, thereby reducing the voltage drop and increasing the current intensity of the corner anode, and the docking plates 3 are fixed to both sides of the anode guide rod 2 by a clamping mechanism 4, so that they are easy to remove during the later pole change.

[0018] A further solution of this embodiment is that the butt joint plate 3 is an aluminum plate, and the aluminum plate is in an "L" shape. More specifically, the butt joint plate 3 is two 150mm*130mm*20mm aluminum plates welded into an "L" shape.

[0019] On the basis of the above embodiment, a further technical solution of the clamping mechanism 4 is that the clamping mechanism 4 includes a bracket 41, a screw rod 44 and a clamping plate 43. The bracket 41 is welded by three pieces of channel steel, and the bracket 41 spans the horizontal busbar 1 and the anode guide rod 2. Screw sleeves 42 are provided on the arms on both sides of the bracket 41, and screw rods 44 are threadedly connected in the screw sleeves 42. A clamping plate 43 is provided at the end of the screw rod 44, and the clamping plate 43 is pressed against the docking plate 3 by screwing the screw rod 44. In order to further improve the stable fixation of the docking plate 3, the clamping plate 43 is circular and a convex body 45 is provided at the center of the clamping plate 43. A groove body 31 is provided on the docking plate 3, and the groove body 31 extends into the convex body 45, so as to further prevent the docking plate 3 from falling.
