Description

Technical Field

[0001] The utility model relates to a short-circuit insulating sleeve device for electrolytic aluminum, belonging to the technical field of improved insulating devices for electrolytic aluminum production. Background Art

[0002] At present, large-scale aluminum electrolytic cells at home and abroad all use a series power supply connection method, and short-circuit explosion is one of the main causes of a series of accidents in the electrolytic aluminum industry. If a short-circuit accident occurs at the short-circuit of an online aluminum electrolytic cell, it will cause a short-circuit explosion, and in severe cases, a series of power outages will occur. If it is not handled in time, it will seriously threaten the safety of the electrolytic cell series, causing the entire production series to stop production and unable to start quickly, causing extremely serious economic losses to the company.

[0003] In the electrolytic aluminum production process, the protection of the insulation state of the short-circuit junction is an extremely important safety protection work. Each start-up and shutdown operation must be performed in the short-circuit junction area. The traditional fixing method is to fix the short-circuit junction with steel bolts through four holes. The disassembly process requires more manpower and material resources, and the disassembly process is cumbersome and time-consuming, and there are greater risks and hidden dangers at critical times. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in view of the shortcomings of the existing situation, a short-circuit insulating sleeve device for electrolytic aluminum is provided to improve the insulation effect of the short-circuit, optimize the operation process, ensure the safety of personnel during the disassembly process, achieve safe production, be beneficial to electrolytic production management, and improve work efficiency.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A short-circuit insulating sleeve device for electrolytic aluminum comprises a short-circuit insulating plate, wherein the short-circuit insulating plate is provided with two groups of insulating sleeve assemblies arranged up and down, and each group of insulating sleeve assemblies comprises two through-insulating rods, a tension bolt, two stainless steel sleeves, a stainless steel sleeve connecting piece and a central fixing hole; the through-insulating rods penetrate the short-circuit insulating plate and the short-circuit busbar to fix the short-circuit busbar without displacement; the two stainless steel sleeves are respectively sleeved on the two through-insulating rods, and the two stainless steel sleeves are connected by the stainless steel sleeve connecting piece; the central fixing hole is provided at the central position of the stainless steel sleeve connecting piece, and the tension bolt passes through the central fixing hole to fix the two stainless steel sleeves and the stainless steel sleeve connecting piece on the short-circuit insulating plate to prevent the short-circuit insulating plate from displacement or falling.

[0007] An annular insulating gasket is arranged between the stainless steel bushing and the short-circuit insulating plate to prevent the stainless steel from contacting the busbar.

[0008] The through-insulating rod, the annular insulating gasket and the short-circuit insulating plate form a double insulating structure, which ensures that the short-circuit busbars are in a highly insulating state and will not cause a short-circuit explosion due to failure of the insulating plate or the insulating rod.

[0009] After the stainless steel sleeve is sleeved on the through-insulating rod, the tightening bolts are tightened to fix the insulating device at the entire short-circuit position to form a short-circuit insulating sleeve device.

[0010] The stainless steel sleeve and the stainless steel sleeve connecting piece are made of anti-magnetic stainless steel material and are an integrated structure to prevent being affected by magnetic force in a high magnetic field environment.

[0011] The innovations of this utility model are as follows:

[0012] 1. The utility model effectively fixes the short-circuit busbar without displacement by penetrating the insulating rod. The penetrating insulating rod, the annular insulating gasket and the short-circuit insulating plate form a double insulation structure to ensure that the short-circuit busbars are highly insulated and will not cause short-circuit explosion due to failure of the insulating plate or the insulating rod.

[0013] 2. The two groups of insulating sleeve components of the utility model are arranged up and down, and four penetrating insulating rods are passed through from one side of the short-circuit and out from the other side, so as to fix the short-circuit busbar without displacement, effectively replacing the traditional steel bar bolts and ensuring a high degree of insulation.

[0014] 3. The tensioning bolt in the utility model is a tensioning device on the connecting plate between a pair of stainless steel sleeves. After the stainless steel sleeve is sleeved on the penetrating insulating rod, the tensioning bolt is tightened to fix the entire device at the short-circuit position to prevent displacement and falling of the insulating plate, and can effectively adjust the tightness of the insulating device.

[0015] 4. The stainless steel sleeve and the stainless steel sleeve connecting piece in the utility model are made of anti-magnetic stainless steel material and are an integrated structure to prevent being affected by magnetic force in a high magnetic field environment.

[0016] 5. The utility model replaces steel bar bolts with insulating rods and replaces traditional bolts with stainless steel casings, so that the short-circuit busbars are highly insulated from each other, which greatly reduces the labor and operation process during the disassembly process. The process is very simple and the effect is better.

[0017] 6. In the actual production of electrolytic aluminum, under the condition of ensuring absolute insulation, the utility model fixes the short-circuit busbar without displacement, and replaces the traditional steel bar screws with penetrating insulating rods to prevent the steel bar screws from conducting electricity after the insulating plate fails for a long time, thereby causing the short-circuit to be uninsulated and explode, which is beneficial to the stable and efficient production of the electrolytic cell.

[0018] 7. The tightening bolts in the utility model adopt 10.9 grade high-strength bolts and are lubricated regularly to prevent rusting over a long period of time and prevent them from being unusable in emergency use.

[0019] The positive and beneficial effects of the utility model are as follows:

[0020] 1. Ensure the high insulation state of the short-circuit junction to prevent the short-circuit junction from exploding due to poor insulation.

[0021] 2. The operation process during trough starting and stopping has been optimized, making the operation simple and safe.

[0022] 3. Reduced the workload of personnel. BRIEF DESCRIPTION OF THE DRAWINGS
