Description

Technical Field

[0001] This utility model relates to the technical field of aluminum electrolytic cell repair equipment, specifically a device for repairing the busbar of an electrolytic cell. Background Technology

[0002] Currently, both domestic and international companies using electrolytic metal smelting methods rely on electricity as their power source and aluminum busbars as the energy transmission material. Since current generates a magnetic field during transmission, this magnetic field increases with the current intensity. In actual production, aluminum busbars can be damaged or broken due to molten metal leakage or other reasons. Furthermore, the contact surfaces of the busbar guide rods in aluminum electrolytic cells are prone to mechanical wear during operation, affecting performance. Therefore, welding repairs of the aluminum busbars are necessary during major overhauls of aluminum electrolytic cells.

[0003] Due to the magnetic field, various welding methods currently used, such as arc welding and gas shielded welding, are subject to interference and influence from magnetic deflection. As a result, an effective molten pool cannot be formed on the weld surface, molten metal spatter cannot be welded to the body for repair, the welding time is longer, the welding stability becomes worse, the welding quality decreases, and the electric arc, sparks and fumes generated during welding can cause harm to the human body, making the operation less safe.

[0004] Therefore, it is necessary to design a repair device for auxiliary electrolytic cell busbars to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a device for repairing electrolytic cell busbars that has a more reasonable structural design, low processing and manufacturing cost, simple repair process, easy operation, high safety performance, fully guarantees the operation safety of operators, has good repair effect, can greatly reduce the maintenance cost of electrolytic cell busbars, quickly repair damaged busbars, and has high repair efficiency.

[0006] This utility model discloses a device for repairing the busbar of an electrolytic cell. Molds are fixedly installed on both sides of the busbar. Rectangular grooves are opened on the side walls of the molds, and aluminum blocks are filled in the rectangular grooves. Heating tubes are provided on the outer walls of the molds.

[0007] The outer wall of the mold is provided with a heat insulation layer, and heating tubes are evenly distributed on the outer wall of the heat insulation layer.

[0008] The number of molds is two, which are respectively set on both sides of the electrolytic cell busbar. A connecting plate is fixedly connected between the two molds. The connecting plate is set to fit the bottom surface of the electrolytic cell busbar, and the two molds are respectively set to fit the two side walls of the electrolytic cell busbar.

[0009] The width of the mold is wider than the width of the electrolytic cell busbar.

[0010] The mold is designed as a two-piece structure, fixed on both sides of the damaged electrolytic cell busbar. This design helps to define the areas requiring modification and provides a clear scope for repair, facilitating the repair work. Rectangular grooves on the side walls of the mold are filled with aluminum blocks, which can be used to repair the damaged electrolytic cell busbar. Two molds are used, one on each side of the electrolytic cell busbar, with a connecting plate fixed between them. The connecting plate is fitted to the bottom surface of the electrolytic cell busbar and fixed to the side walls and bottom surface of the busbar via welding, ensuring a tight fit. The joints are sealed with refractory material to prevent leakage of molten aluminum, thus guaranteeing the quality of the repaired electrolytic cell busbar.

[0011] The heating element is equipped with cooling water and direct current (DC). Utilizing the working principle of a medium-frequency induction furnace—specifically, electromagnetic induction—the three-phase AC power is rectified into DC power, which is then converted into an adjustable medium-frequency current. This current supplies a circuit consisting of a capacitor and an induction coil. High-density magnetic lines of force are generated in the induction coil, cutting through the metal material placed within. This generates large eddy currents within the metal material, inducing eddy currents within the ferromagnetic material and causing it to heat up. Therefore, the heating element can be further... The heating process involves heating the insulation layer by wrapping the heating tubes around it. This heats the insulation layer and ultimately the mold. Induction eddy currents are generated inside the mold, heating the aluminum blocks that fill it. The aluminum blocks melt, and once they fuse with the damaged electrolytic cell busbar, the power is cut off to maintain the temperature. This process allows the aluminum blocks and the damaged electrolytic cell busbar to fuse together and gradually solidify, ultimately repairing the damaged electrolytic cell busbar. The operation is simple, easy to perform, and safe, ensuring a safe working environment for operators.

[0012] The insulation layer is made of high-temperature resistant ceramic fiber cloth.

[0013] The thickness of the insulation layer is 6-8 cm.

[0014] The insulation layer, made of high-temperature resistant ceramic fiber cloth, is designed to keep the temperature warm after the operator disconnects the power. It has the advantages of high temperature resistance, low thermal conductivity, thermal shock resistance, and low heat capacity. It can keep heated molds, aluminum blocks, and damaged electrolytic cell busbars warm and has a long service life.

[0015] The heating tube is fixedly connected to a sealing cap at its end, and the sealing cap is threadedly connected to the end of the heating tube.

[0016] The heating element is designed so that cooling water can be injected into it. Once the heating element is full, a sealing cap is threadedly connected to the end of the heating element to seal it. After use, the sealing cap can be opened to drain the water. The system is easy to operate and has high safety performance.

[0017] The beneficial effects of this utility model are:

[0018] 1) The mold is set up as a two-piece structure, which is fixed on both sides of the damaged electrolytic cell busbar. This is used to determine the location that needs to be modified, providing a clear range for the repair work and facilitating the operation. Aluminum blocks can be filled into the rectangular grooves opened on the side wall of the mold. The filled aluminum blocks can be used to repair the damaged electrolytic cell busbar. There are two molds, which are set on both sides of the electrolytic cell busbar. A connecting plate is fixed between the two molds. The connecting plate is set against the bottom surface of the electrolytic cell busbar and fixed to the side walls and bottom surface of the electrolytic cell busbar by welding. It fits tightly with the damaged electrolytic cell busbar. The joint is sealed with refractory material to prevent the aluminum liquid from leaking out after melting, so as to fully guarantee the repair quality of the damaged electrolytic cell busbar.

[0019] 2) The heating element is equipped with cooling water and direct current (DC). Utilizing the working principle of a medium-frequency induction furnace—specifically, electromagnetic induction—the three-phase AC power is rectified into DC power, which is then converted into an adjustable medium-frequency current. This current is supplied to a circuit consisting of a capacitor and an induction coil. High-density magnetic lines of force are generated in the induction coil, cutting through the metal material placed within it. This generates large eddy currents within the metal material, inducing eddy currents within the ferromagnetic material and causing it to heat up. Therefore, the heating element can be... Heating is performed by heating the insulation layer, which is covered by heating tubes. This process heats the insulation layer and ultimately the mold. Induction eddy currents are generated inside the mold, which in turn heat the aluminum block inside, causing it to melt. Once the aluminum block and the damaged electrolytic cell busbar are fused together, the power is cut off and the mold is kept warm. This process allows the aluminum block and the damaged electrolytic cell busbar to fuse together and gradually solidify, ultimately repairing the damaged electrolytic cell busbar. The operation is simple, easy to operate, and safe and reliable, ensuring the safety of the operator's working environment.

[0020] 3) The insulation layer is made of high-temperature resistant ceramic fiber cloth. It has the advantages of high temperature resistance, low thermal conductivity, thermal shock resistance and low heat capacity. It can keep heated molds, aluminum blocks and damaged electrolytic cell busbars warm and has a long service life.

[0021] 4) The heating tube is equipped with a cooling water filling system. Once the cooling water is full, the heating tube is sealed by connecting the sealing cap to the end of the heating tube with a thread. After the repair and use are completed, the sealing cap can be opened to pour out the water. The operation is convenient and the safety performance is high.

[0022] 5) This repair device has a more reasonable structural design, low processing and manufacturing costs, simple repair process, easy operation, and high safety performance. It fully guarantees the safety of operators, has good repair effect, can greatly reduce the maintenance cost of electrolytic cell busbars, quickly repair damaged busbars, and has high repair efficiency. It is currently in use and the effect is good. It is worth promoting and applying it on a large scale. Attached Figure Description

The joint is sealed with refractory material to prevent leakage of molten aluminum. Cooling water is introduced into the heating tube 4, followed by direct current. Utilizing the working principle of a medium-frequency electric furnace (i.e., electromagnetic induction), the three-phase AC power is rectified into DC power, which is then converted into DC power. An adjustable medium-frequency current is supplied to the circuit composed of a capacitor and an induction coil, generating high-density magnetic lines of force in the induction coil. These lines cut through the metal material contained within the induction coil, generating large eddy currents in the metal material. This causes induced eddy currents to form inside the ferromagnetic material, generating heat and achieving the purpose of heating the material. Therefore, the heating tube 4 and the mold 3 can be heated. Induced eddy currents are generated inside the mold 3, generating heat and heating the aluminum block 5 filled inside the mold 3, causing the aluminum block 5 inside the mold 3 to melt. When the aluminum block 5 and the damaged electrolytic cell busbar 1 fuse together, the power is cut off for heat preservation, allowing the aluminum block 5 and the damaged electrolytic cell busbar 1 to fuse together and gradually solidify, ultimately repairing the damaged electrolytic cell busbar 1.

This process heats the heating tube 4, which in turn heats the insulation layer 2, which in turn heats the mold 3. The induced eddy currents inside the mold 3 heat the aluminum block 5 filled within it, causing it to melt. Once the aluminum block 5 fuses with the damaged electrolytic cell busbar 1, the power is cut off for heat preservation, allowing the aluminum block 5 and the damaged electrolytic cell busbar 1 to fuse and gradually solidify, ultimately repairing the damaged electrolytic cell busbar 1.
