Novel aluminum electrolysis slotting soft connection design

Abstract

The invention discloses a novel aluminum electrolysis slotting soft connection design. The novel aluminum electrolysis slotting soft connection design comprises a guide rod. A soft connection soft belt bundle is arranged on the outer side of the guide rod. A soft connection upper aluminum block and a soft connection lower aluminum block are correspondingly fixed to the two ends of the soft connection soft belt bundle. A horizontal bus duct is fixed to the outer wall of the lower end of the guide rod. A frame body is fixed to the outer wall of the horizontal bus duct. The soft connection loweraluminum block is located between the inner top wall of the frame body and the inner top wall of the horizontal bus duct. A fastening bolt with the lower end being in contact with the upper side wallof the soft connection lower aluminum block is screwed to the frame body. A U-shaped angle steel plate is arranged on the outer wall of the upper end of the guide rod. A rib plate penetrating the guide rod is fixed between the two ends of the angle steel plate. According to the novel aluminum electrolysis slotting soft connection design, an arc-shaped part is arranged on the soft connection soft belt bundle, the soft connection length is reduced, the resistivity is reduced, the size of the soft connection upper aluminum block and the soft connection lower aluminum block is optimized, direct mounting is carried out to reduce the pressure drop, and the problem that the traditional welding pressure drop is large is avoided.

Description

technical field [0001] The invention relates to the technical field of electrolytic cells, in particular to the design of a novel flexible connection for aluminum electrolytic slotting. Background technique [0002] The electrolytic cell is composed of a cell body, an anode and a cathode, most of which are separated by a diaphragm from the anode chamber to the cathode chamber. According to the different electrolytes, it is divided into three types: aqueous solution electrolyzer, molten salt electrolyzer and non-aqueous solution electrolyzer. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. Optimizing the design of the electrolytic cell structure and rational selection of electrode and diaphragm materials are the key to improving current efficiency, reducing cell voltag...

Problems solved by technology

[0003] The conductive section of the traditional slotted soft connection used in the slotting of large prebaked electrolytic cells is the same size as the anode guide rod. It is installed on the pin hole at the end of the guide rod and the top of the horizontal bus bar of the anode. The length is more than 1 meter and the weight is more than 50 kg. It is bulky, and the traditional SY series electrolyzer horizontal bus adopts a triangular plate lifting mechanism, and each electrolyzer has 8 guide rods with narrow installation positions, so it is impossible to install soft connections according to the traditional method
