[0001] The utility model relates to the technical field of aluminum electrolysis, in particular to an online replacement device for a busbar backing plate of an electrolytic cell. Background Art

[0002] When the electrolytic cell is expanded to 180kA, it is usually necessary to install an aluminum backing plate between the anode busbar and the anode guide rod, and to secure the aluminum backing plate with anode hook bolts. During long-term operation, the aluminum backing plate voltage drop will continue to increase due to loosening, breakage, or failure of the bolts, which will in turn increase the reactive power consumption of the electrolytic cell. Therefore, in order to reduce the power consumption of the electrolytic cell, aluminum backing plates with excessive voltage drop need to be replaced in a timely manner.

[0003] In the prior art, when replacing the aluminum pad, the anode guide rod is usually lifted out of the electrolytic cell with the help of an overhead crane so that the anode guide rod no longer blocks the aluminum pad, and the aluminum pad can be manually disassembled and assembled. This not only increases the occupancy time of the overhead crane, but also after the anode guide rod is lifted out, the smoke and high temperature of the electrolytic cell will have a certain adverse effect on the health of the operators, and there is a certain probability of causing illness if dust and gas are inhaled for a long time.

DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-4 As shown, this embodiment discloses an online replacement device for the busbar pad of an electrolytic cell, including a horizontal pushing mechanism 1, the fixed end of which is detachably connected to the I-beam 2 of the electrolytic cell truss, and the action end of the horizontal pushing mechanism 1 is abutted against the side of the anode guide rod 4 through the insulating plate 1 3; one end of the positioning mechanism 5 is detachably connected to the anode guide rod 4, and the other end is slidably fitted with the top surface of the anode busbar 7 through the insulating plate 2 6.

[0026] In this embodiment, the insulating plate 1 3 is used to prevent electrical connection between the horizontal pushing mechanism 1 and the electrolytic cell truss, and the insulating plate 2 6 is used to prevent electrical connection between the positioning mechanism 5 and the anode busbar 7.

[0027] By adopting this solution, the anode guide rod 4 can be pushed in the horizontal direction by the horizontal pushing mechanism 1, so that a certain operating gap is left between the anode guide rod 4 and the aluminum pad 8, which is convenient for the disassembly and assembly of the aluminum pad 8; the anode guide rod 4 can be positioned during the pushing process by the positioning mechanism 5, so as to prevent the anode guide rod 4 from sliding down and causing instability in the electrolytic cell; the insulating plate 1 3 and the insulating plate 2 6 can ensure safety during operation; through the coordinated use of the above-mentioned structures, when the aluminum pad 8 is replaced, the utility model no longer needs to use a crane to lift the anode guide rod 4 out of the electrolytic cell, which not only greatly reduces the occupancy time of the crane, but also does not generate high temperature and smoke in the operation area, thereby ensuring the safety of personnel during operation.

[0028] Further optimized solution, the horizontal pushing mechanism 1 includes a connection component 11 detachably connected to the electrolytic cell truss I-beam 2. One side of the connection component 11 is fixedly connected with a sleeve 12, the end of the sleeve 12 is fixedly connected with a nut 13, a jackscrew 14 is threadedly connected in the nut 13, one end of the jackscrew 14 extends into the sleeve 12, and the other end of the jackscrew 14 abuts against the side of the anode busbar 4 through an insulating plate 1 3; A first force application component 15 is connected to the jackscrew 14, and the first force application component 15 is located between the nut 13 and the insulating plate 1 3.

[0029] In this embodiment, the sleeve 12 is used to guide the jackscrew 14, and the first force application component 15 is used to drive the jackscrew 14 to rotate. By the threaded connection between the jackscrew 14 and the nut 13, when the jackscrew 14 rotates, it can perform a linear motion in the horizontal direction, so as to apply a horizontal pushing force to the anode busbar 4.

[0030] Further optimized solution, the connection component 11 includes a connection seat 111 connected to the sleeve 12, and the connection seat 111 is detachably connected to the electrolytic cell truss I-beam 2 through a pin 112.

[0031] In this embodiment, the connection seat 111 is of a U-shaped structure. The side wall of the connection seat 111 is fixedly connected to the end face of the sleeve 12. A plurality of spaced-apart mounting holes 1110 are provided on both the upper wall and the lower wall of the connection seat 111, and the mounting holes 1110 on the upper wall correspond to the mounting holes 1110 on the lower wall one by one; Through holes are provided on the upper flange plate of the electrolytic cell truss I-beam 2. One end of the pin 112 sequentially passes through the mounting hole 1110 on the upper wall, the through hole, and the mounting hole 1110 on the lower wall, and the pin 112 is locked by a split pin to prevent left-right shaking and displacement.

[0033] Further optimized solution, the positioning mechanism 5 includes a mounting frame 51 sleeved on the anode busbar 4. An abutting rod 52 is provided through one side of the mounting frame 51. One side of the abutting rod 52 is threadedly connected to the mounting frame 51, and the other side of the abutting rod 52 is connected to a second force application component 53; A plurality of spaced-apart legs 54 are connected to the side of the mounting frame 51 away from the abutting rod 52. The ends of the legs 54 are slidably mated with the top surface of the anode bus 7 through an insulating plate 2 6.

[0034] In this embodiment, the force-applying component 2 53 is used to drive the abutment rod 52 to rotate.

In conjunction with the provided support legs 54, it can effectively prevent the anode guide rod 4 from sliding down during the pushing process of the anode guide rod 4.

[0036] In a further optimized solution, the second force-adding assembly 53 includes a second mounting sleeve 531 fixedly connected to the end of the abutting rod 52, and a second force-adding tube 532 is fixedly inserted into the second mounting sleeve 531. The second force-adding tube 532 and the second mounting sleeve 531 facilitate the rotation of the abutting rod 52.

[0037] When used, the utility model comprises the following steps:

[0038] S1. Select the anode busbar aluminum backing plate 8 that needs to be replaced, clean the dust on the anode busbar 7, aluminum backing plate 8 and anode guide rod 4, and check whether the cell cover of the electrolytic cell is firm and insulated.

[0039] S2. Place the second insulating plate 6 on the top surface of the anode busbar 7, insert the mounting frame 51 from the top of the anode guide rod 4, and make the support legs 54 rest on the second insulating plate 6, and then use the second force component 53 to tightly press the abutting rod 52 against the side of the anode guide rod 4.

[0041] S4. Remove the fixtures securing the anode guide rod 4 and use the force-applying assembly 15 to push the anode guide rod 4, creating a 50mm operating gap between the anode guide rod 4 and the aluminum backing plate 8. The weight of the anode guide rod 4 transfers the force point to the anode busbar 7 via the positioning mechanism 5. During and after the pushing process, the anode guide rod 4 will not sway or tilt due to its own weight.

[0042] S5. Use insulating rubber to wrap the anode guide rod 4 to prevent electrical connection during operation.

[0045] S8. After replacing the new aluminum pad 8, install the anode hook bolts and hooks, remove the horizontal pushing mechanism 1, and return the anode guide rod 4 to its original position close to the aluminum pad 8; install the fixture to fix the anode guide rod 4, and then remove the positioning mechanism 5 to complete the replacement operation of the aluminum pad 8.
