Description

Technical Field

[0001] This utility model relates to the field of machinery, specifically to a busbar support for an electrolytic cell. Background Technology

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode, with the anode chamber and cathode chamber usually separated by a diaphragm. The aluminum electrolytic cell is one of the main production equipment in aluminum electrolysis enterprises. In practice, aluminum electrolytic cells operate at low voltage and high current, so insulation and busbar conductivity are perpetual concerns in the aluminum electrolysis industry.

[0003] The tank is divided into an upper part and a lower part. The cathode busbar mainly includes a balance busbar (also called a horizontal busbar), a flexible strip busbar, and a column busbar. The balance busbar is connected to the upper part of the tank through a lifting and adjusting device. One end of the flexible strip busbar is fixed to the side wall of the balance busbar, and the other end is movably installed on the column busbar. An anode guide rod is installed on the balance busbar. As the carbon block at the bottom of the anode guide rod is consumed in the lower part of the tank, the balance busbar will descend with the anode guide rod, so the flexible strip busbar is in a flexible state.

[0004] The balancing busbar suffers from side burns due to current flowing through the anode conductor, affecting the conductor's conductivity. It needs to be repaired and leveled. Usually, one end of the flexible busbar is separated from the column busbar, and then the upper part of the trough is lifted out and placed in an open area. The balancing busbar and the flexible busbar are lifted out along with it. Because the flexible busbar is soft and heavy, it is prone to sagging, which can cause deformation or damage when it hits the ground. Therefore, a support bracket needs to be designed to support the flexible busbar. Utility Model Content

[0005] The purpose of this utility model is to provide a busbar support for an electrolytic cell.

[0006] This utility model is implemented by the following technical solution:

[0007] An electrolytic cell busbar support includes an L-shaped top rod, a pull rod, and a support rod. The L-shaped top rod is horizontally placed at the top of the upper part of the cell, with its bent end hooking onto the upper part of the cell. The other end of the L-shaped top rod is horizontally and vertically fixed to an upper arc-shaped plate. The support rod is horizontally placed below the flexible busbar, with a vertical abutment plate fixed to one end of the support rod. The abutment plate abuts against the side wall of the upper part of the cell. The other end of the abutment plate is horizontally and vertically fixed to a lower arc-shaped plate. The upper and lower arc-shaped plates are horizontally arranged relative to each other. Both ends of the upper and lower arc-shaped plates are fixed with screws. Pull rods are respectively provided at both ends of the upper and lower arc-shaped plates. Each pull rod has a through hole at both ends. The two ends of one pull rod are respectively fitted onto the screws on the same side of the upper and lower arc-shaped plates through the through holes. Nuts that prevent the pull rods from coming out are screwed onto the screws.

[0008] The support rod is fixed with a leg structure that supports the ground by rotation.

[0009] Preferably, a boss is fixed to the bottom of the L-shaped top rod, a rotating shaft is fixed to the bottom of the boss, a limiting plate is rotatably sleeved on the rotating shaft, the top of the limiting plate abuts against the bottom of the top edge of the upper part of the groove, and a nut is screwed onto the rotating shaft to restrict the rotation of the limiting plate.

[0010] Preferably, the support leg structure includes a support plate with a longitudinal section of "7" shaped fixed on the support rod. Baffles are fixed at both ends of the support plate. Support rods that are rotatably connected to the baffles are respectively provided inside both ends of the support plate. An intermediate ring is slidably sleeved on the support rod. Side rings that are slidably sleeved on the two support rods are fixed on both sides of the intermediate ring.

[0011] Preferably, the end of the support rod facing the side ring is arc-shaped.

[0012] Preferably, the support leg structure includes an inverted V-shaped connecting rod fixed to the load-bearing rod, with support rods at both ends of the inverted V-shaped connecting rod. The end faces of both ends of the inverted V-shaped connecting rod are inclined surfaces, and the inclined surfaces at both ends of the inverted V-shaped connecting rod are rotatably connected to the inclined surfaces at one end of the support rods.

[0013] Advantages of this invention: The flexible busbar falls naturally and is supported by the support rod at the bottom. At the same time, one end of the support rod located below the flexible busbar is also pulled upward by two pull rods. The pull rods are pulled by the L-shaped top rod at the top of the groove, providing tension and further suspending the flexible busbar to prevent it from hitting the ground.

[0014] The removal of the nut from the screw facilitates the installation of the pull rod on the upper and lower arc plates, and makes it convenient for the bracket of this application to be disassembled and assembled on the flexible busbar.

[0015] The rotating limiting plate has its top abutting against the bottom of the top edge of the upper part of the groove and is locked by a nut to prevent the limiting plate from moving, thus serving the function of hanging the L-shaped top rod on the top of the upper part of the groove.

[0016] When assembling or disassembling the support structure of this application, especially the support for the load-bearing rod, the outrigger structure can be used to provide temporary support and stabilize the posture. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figures 1-6As shown, an electrolytic cell busbar support includes an L-shaped top rod 1, a pull rod 2, and a support rod 3. The L-shaped top rod 1 is horizontally placed on top of the upper part 4 of the cell, with its bent end hooking onto the upper part 4. The other end of the L-shaped top rod 1 is horizontally and vertically fixed to an upper arc plate 5. The support rod 3 is horizontally placed below the flexible busbar 6, with a vertical abutment plate 7 fixed to one end of the support rod 3. The abutment plate 7 abuts against the side wall of the upper part 4, with its surface pressing against the side wall, making the support rod 3 horizontal. The other end of the abutment plate 7 is horizontal and vertical. A lower arc plate 8 is fixed, and the arc surface of the lower arc plate 8 contacts the soft strip busbar 6 to avoid pressing marks and prevent damage. The upper arc plate 5 and the lower arc plate 8 are set horizontally to each other. Both ends of the upper arc plate 5 and the lower arc plate 8 are fixed with screw rods 9. Pull rods 2 are provided at both ends of the upper arc plate 5 and the lower arc plate 8. Both ends of the pull rods 2 are provided with through holes 10. The two ends of a pull rod 2 are respectively sleeved on the screw rods 9 on the same side of the upper arc plate 5 and the lower arc plate 8 through the through holes 10. Nuts 11 that prevent the pull rods 2 from coming off are screwed onto the screw rods 9.

[0030] The flexible busbar 6 falls naturally, relying on gravity to press down on the lower arc plate 8. The force is directed towards the lower half of the upper part 4 of the groove. The flexible busbar 6 is supported by the support rod 3. At the same time, the lower arc plate 8 is also pulled upward by two pull rods 2. The pull rods 2 are hooked on the L-shaped top rod 1 of the upper part 4 of the groove and pulled to provide tension, which also further suspends the flexible busbar 6 and prevents the lower arc plate 8 from swaying left and right.

[0031] The removal of nut 11 from screw 9 facilitates the installation of pull rod 2 on upper arc plate 5 and lower arc plate 8, and makes it convenient for the bracket of this application to be installed and removed from the flexible busbar 6.

[0032] A support leg structure 12 is fixed to the load-bearing rod 3, which supports the ground by rotation. When assembling or disassembling the bracket of this application, especially the support of the load-bearing rod 3, the support leg structure 12 can be used to provide temporary support and stabilize the posture.

[0033] The bottom of the L-shaped top rod 1 is fixed with a boss 13, and the bottom of the boss 13 is fixed with a rotating shaft 14. A limiting plate 15 is rotated on the rotating shaft 14. The top of the limiting plate 15 abuts against the bottom of the top edge of the upper part of the groove 4. A nut 11 is screwed onto the rotating shaft 14 to limit the rotation of the limiting plate 15.

[0034] The rotating limiting plate 15, with its top abutting against the bottom of the top edge of the upper part 4 of the groove, is locked by the nut 11 to prevent the limiting plate 15 from moving. This serves to temporarily hang the L-shaped top rod 1 on the top of the upper part 4 of the groove. It can prevent the L-shaped top rod 1 from being misaligned when disassembling and assembling the bracket of this application, and it can also limit the movement of the L-shaped top rod 1 when suspending the soft busbar 6.

[0035] The outrigger structure 12 includes a support plate 16 with a longitudinal section of "7" shaped fixed on the support rod 3. Both ends of the support plate 16 are fixed with baffles 17. The two ends of the support plate 16 are respectively provided with support rods 18 that are rotatably connected to the baffles 17. An intermediate ring 19 is slidably sleeved on the support rod 3. Side rings 20 that are slidably sleeved on the two support rods 18 are fixed on both sides of the intermediate ring 19.

[0036] The two support rods 18 rotate upwards, and are limited by the top of the support plate 16, so that they are in a horizontal state. The sliding middle ring 19 causes the two side rings 20 to be fitted onto the two support rods 18, so that the two support rods 18 do not fall off, which is conducive to moving the bracket of this application. The sliding middle ring 19 causes the two side rings 20 to leave the two support rods 18, and the two support rods 18 rotate downwards, and are limited by the side of the support plate 16, so that they are in a vertical state. The distance from the bottom of the load-bearing rod 3 to the ground is supported, which is conducive to stabilizing the posture of the load-bearing rod 3 when assembling and disassembling the bracket of this application.

[0037] The end of the support rod 18 facing the side ring 20 is arc-shaped, which reduces the contact area with the ground and makes it easier to lift the support rod 18 after the bracket of this application is installed.

[0038] Working principle: such as Figure 5 As shown, when installing the bracket of this application, the flexible busbar 6 is lifted by one end by the overhead crane. The bent end of the L-shaped top rod 1 is hooked onto the upper part 4 of the groove by a worker, so that the L-shaped top rod 1 is placed above the flexible busbar 6. The limiting plate 15 is rotated so that its top abuts against the bottom of the top edge of the upper part 4 of the groove and is locked by the nut 11 to prevent the limiting plate 15 from moving. The worker uses the support leg structure 12 to temporarily support the load-bearing rod 3. One end of the load-bearing rod 3 is abutted against the side wall of the upper part 4 of the groove through the plate surface of the abutment plate 7, and the other end is supported by the bottom of the flexible busbar 6 through the lower arc plate 8. Two pull rods 2 are installed between the upper arc plate 5 and the lower arc plate 8.

[0039] The flexible busbar 6 falls naturally, relying on gravity to press down and is supported by the support rod 3. At the same time, the pull rod 2 pulls between the support rod 3 and the L-shaped top rod 1 of the hook groove 4, providing tension and suspending the flexible busbar 6.

[0040] Finally, lift the two support rods 18, limit them with the middle ring 19 and the side ring 20, and hoist the upper part 4 of the trough through the overhead crane.

[0041] Example 2

[0042] like Figure 7 , Figure 8As shown, an electrolytic cell busbar support has the same overall structure as Embodiment 1, except that the support leg structure 12 includes an inverted V-shaped connecting rod 21 fixed to the load-bearing rod 3. Support rods 18 are provided at both ends of the inverted V-shaped connecting rod 21. The end faces of both ends of the inverted V-shaped connecting rod 21 are inclined surfaces, but these inclined surfaces are nearly horizontal. The inclined surfaces at both ends of the inverted V-shaped connecting rod 21 are respectively engaged with the inclined surfaces at one end of the support rod 18 for rotational connection. The end of the support rod 18 matches the inclined surface at the end of the inverted V-shaped connecting rod 21. When the support rod 18 is rotated, it rotates along the inclined surface. Therefore, the support rod 18 can change its orientation horizontally and downwards. When horizontal, it facilitates the movement of the support; when downwards, it facilitates the stability of the load-bearing rod 3 during assembly and disassembly of the support.

[0043] Working principle: Same as in Example 1, except that the rotation of the two support rods 18 can change the horizontal and downward orientation without the need for the middle ring 19 and side ring 20 to limit it.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
