Description

Technical Field

[0001] The utility model relates to a shunt, in particular to an anti-deformation shunt for electrolytic aluminum, belonging to the technical field of tool transformation in mechanical engineering technology. Background Art

[0002] During the startup of aluminum electrolysis, the purpose of the roasting process is to heat the anode and cathode to a suitable operating temperature before starting up and entering normal later production.

[0003] In the baking stage, in order to avoid the fuse of the guide rod caused by excessive anode conductive bias during the baking process, the industry generally uses a shunt to connect the electrolytic cell parallel busbar and the column busbar to distribute the full current, reduce the anode current and starting impact voltage, and ensure a smooth, safe and smooth starting process.

[0004] At present, the old-style shunts in the industry generally do not use fixing devices, which leads to softening due to conductive heat during the use of the shunt. When the shunt iron sheets soften, they will stack together under the action of gravity, which is very easy to form a short circuit and cause heat accumulation, resulting in deformation and melting of the shunt iron sheets of the shunt, which poses the risk of shunt damage and electrolytic cell startup accidents. Therefore, when using the old-style shunts, the inspectors generally take air cooling measures to prevent the shunt from melting after finding that the shunt is overheated. After use, if it needs to be reused, it needs to be manually calibrated by personnel, which consumes a lot of human resources and air compressor resources, increasing costs. Utility Model Content

[0005] The technical problems to be solved by the present invention are as follows: In view of the fact that the existing old-style electrolytic aluminum shunt will soften due to conductive heat during use, and adjacent iron sheets stacked together under the action of gravity will cause a short circuit, an anti-deformation shunt for electrolytic aluminum is provided to effectively reduce the degree of deformation of the shunt, reduce the labor intensity of correction during repeated use, and reduce the risk of startup accidents caused by melting due to excessive extension and stacking of shunt iron sheets.

[0006] The technical solutions adopted by the utility model to solve the technical problems are as follows:

[0007] A deformation-proof shunt for electrolytic aluminum comprises a column busbar crimping surface portion, a parallel busbar crimping surface portion, a shunt portion and a fixed portion. The shunt portion is composed of n shunt iron sheets of the same length, which are equidistantly distributed, one end of which is welded to the column busbar crimping surface portion, and the other end of which is welded to the parallel busbar crimping surface portion; the fixed portion has m+1 groups, which are equidistantly arranged on the shunt portion, and each group of fixed portions comprises n-1 fixed units, which are respectively fixed in sequence up and down between the n shunt iron sheets.

[0008] The column busbar crimping surface part includes a column busbar crimping aluminum block and a column busbar shunt iron block, the column busbar crimping aluminum block and the column busbar shunt iron block are welded together, the left side of the column busbar crimping block is installed on the column busbar, and the right side of the column busbar shunt iron block is welded together with the left ends of n shunt iron sheets; the parallel busbar crimping surface part includes a parallel busbar crimping aluminum block and a parallel busbar shunt iron block, the parallel busbar crimping aluminum block and the parallel busbar shunt iron block are welded together, the right side of the parallel busbar crimping block is installed on the parallel busbar, and the left side of the parallel busbar shunt iron block is welded together with the right ends of n shunt iron sheets.

[0009] The fixing unit is in a "U" shape, with the bottom protruding upward at a certain arc, and the outer sides of the lower left corner and the lower right corner are arc-shaped, so that the fixing unit can be inserted between two adjacent shunt iron sheets for fixation.

[0010] The column busbar crimping surface part and the parallel busbar crimping surface part are respectively inclined to the left and right sides, and the inclination angle β thereof is 120-150 degrees, and are respectively installed on the column busbar and the parallel busbar.

[0011] The fixing unit is made of insulating material to prevent the occurrence of a short circuit caused by adjacent iron sheets being stacked together under the action of gravity.

[0012] Wherein, n≧13, which is a natural number; m is 2, 4 or 6, and the value of m is determined according to the length of the iron sheet of the shunt part.

[0013] During the process of electrifying the electrolytic cell, the material of the shunt iron sheet in the shunt part will be deformed due to high heat during the electrification process. As the temperature rises, the iron sheet gradually expands under the action of gravity, and the crimping slopes of the column busbar crimping surface and the parallel busbar crimping surface lose their angles due to the expansion of the shunt iron sheet. The fixed part of the utility model can effectively fix the shunt iron sheet in the shunt part, effectively reduce the degree of deformation of the shunt part, reduce the labor intensity of repeated correction, and greatly reduce the risk of startup accidents caused by excessive expansion and stacking of the shunt iron sheet, which leads to melting, and plays a role in reducing tool maintenance costs, reducing accident hazards, increasing work efficiency, and improving the working environment.

[0014] During the installation process, since the shunt part forms an arc surface under the action of the fixed part, the crimping surface of the column busbar can be directly installed on the column busbar using an overhead crane for hoisting without correction, which reduces the operating procedures, reduces labor intensity, and improves operating flexibility.

[0015] During the power-on roasting process, as the full current passes through the shunt part, the shunt iron sheet generates heat energy under the action of resistance. After being heated to above 700°C, the shunt iron sheet will extend downward under the action of gravity. At this time, the fixed part installed on the shunt part will provide mechanical force to support the shunt iron sheet to maintain its original shape, reduce the occurrence of deformation, reduce the correction process required for the reuse of the shunt, and reduce the stacking phenomenon that occurs after the shunt falls, thereby reducing labor intensity, reducing the risk of shunt fusing caused by shunt sheet stacking, and improving the safety performance of the operation and the work efficiency of the operator.

[0016] The positive and beneficial effects of the utility model are as follows:

[0017] 1. The utility model reduces the influence of the thermal effect caused by the energization of the shunt by setting the fixed part, including the thermal effects of the shunt iron sheet softening, the shunt iron sheet deformation, the shunt iron sheet stack fusing, etc., reduces the labor intensity and human resource cost of secondary utilization, and improves the installation efficiency.

[0018] 2. The utility model reduces the possibility of the shunt fusing during use, thereby reducing the probability of poor electrolytic cell startup effect or even potential accidents, by providing a fixed part, thereby improving the safety of the shunt.

[0019] 3. The utility model fixes the angle between the shunt part and the crimping surface parts on both sides at 120 to 150 degrees during installation. Under the action of the fixing part, the shunt as a whole can be directly installed on the electrolytic cell and the busbar without adjustment, which greatly reduces the labor intensity of employees and improves the installation efficiency.
