Description

Technical Field

[0001] This utility model belongs to the field of current supply devices for aluminum electrolytic cells, and in particular relates to a current diversion device for starting an aluminum electrolytic cell. Background Technology

[0002] Modern large-scale prebaked aluminum electrolytic cells mostly employ coke granule roasting for startup. The uniformity of coke granule distribution affects the current distribution. Under full-current startup conditions, excessive current can cause significant impact on the electrolytic cell, affecting its service life. To reduce current surges, a current shunt needs to be installed on the aluminum electrolytic cell to divert the current during coke granule roasting startup.

[0003] For example, Chinese utility model patent with authorization announcement number CN209114003U and authorization announcement date of July 16, 2019 discloses a novel 600 kA electrolytic cell slotted shunt. The shunt includes several shunt plates and partition plates. One end of each shunt plate is connected to the horizontal busbar through a horizontal busbar end crimping plate, and the other end of each shunt plate is connected to the column busbar through a column busbar end crimping plate. The partition plates are arranged between every two shunt plates, and each partition plate is connected to the shunt plate by welding.

[0004] Specifically, the column busbar end crimping plate (equivalent to the column busbar crimping assembly) is detachably connected to the column busbar via a π-type hanging plate clamp; the horizontal busbar end crimping plate (equivalent to the horizontal busbar crimping assembly) is detachably connected to the horizontal busbar via a U-type clamp.

[0005] During operation, the splitter plates generate a large amount of heat, which can cause them to overheat and deform. If the deformation is too great, the splitter plate must be scrapped. In the above-mentioned splitter, since all the splitter plates and splitter plates are welded together, if any one of the splitter plates deforms too much, the entire splitter must be scrapped, resulting in high operating costs.

[0006] The background technology of the aforementioned Chinese utility model patent also discloses a current divider, which is welded together from a crimping plate (equivalent to a horizontal busbar crimping assembly and a column busbar crimping assembly) and a steel strip (equivalent to a current divider plate). When the deformation of any one of the steel strips is too large, the entire current divider needs to be scrapped, resulting in high operating costs. Utility Model Content

[0007] The purpose of this utility model is to provide a current shunt device for starting an aluminum electrolytic cell, so as to solve the technical problem of high operating costs of existing shunt devices.

[0008] To achieve the above objectives, the technical solution of the current shunting device for starting an aluminum electrolytic cell provided by this utility model is as follows:

[0009] A current shunting device for starting an aluminum electrolytic cell includes a horizontal busbar crimping assembly, a column busbar crimping assembly, and a current shunting plate.

A single shunt assembly includes at least two fixedly connected shunt plates, and the two ends of the shunt assembly are detachably connected to a horizontal adapter and a vertical adapter, respectively.

[0012] Alternatively, there may be at least three flow dividers, of which at least two flow dividers are fixedly connected to form a flow divider assembly. The number of flow divider assemblies may be at least one, in which at least one flow divider is arranged independently. The two ends of the independently arranged flow divider are detachably connected to the horizontal adapter and the vertical adapter, respectively. The two ends of the flow divider assembly are detachably connected to the horizontal adapter and the vertical adapter, respectively.

[0013] Furthermore, the horizontal adapter and / or the column adapter includes an adapter plate with receiving grooves on the adapter plate, both ends of the diverter are located in the corresponding receiving grooves, and the adapter plate and the diverter are detachably connected by fasteners.

[0014] Furthermore, the portion of the diverter plate located in the receiving groove and the adapter plate are provided with through holes. The fastener is a double-ended screw, which passes through the through holes on both the diverter plate and the adapter plate. Both ends of the double-ended screw are connected with nuts to enable detachable connection between the diverter plate and the horizontal adapter or the vertical adapter.

[0015] Furthermore, the horizontal adapter and / or the vertical adapter includes a main body and a plurality of conductive strips connected to the main body. Each conductive strip includes a contact portion for conductive contact with the shunt plate. The arrangement direction of the shunt plate is defined as a first direction. The contact portions are evenly spaced along the first direction. A receiving gap is formed between two adjacent contact portions to accommodate the end of the shunt plate. The contact portions and the shunt plate are detachably connected by fasteners.

[0016] Furthermore, in the first direction, the contact portions are located on both sides of the main body portion, and a receiving gap for accommodating the end of the splitter is also formed between the main body portion and the adjacent contact portion. An end plate is provided on the outer side of the outermost contact portion, and a receiving gap for accommodating the end of the splitter is also formed between the end plate and the outermost contact portion. The end plate, contact portions, splitter, and main body portion are detachably connected by fasteners.

[0017] Furthermore, the horizontal adapter and / or the column adapter includes a stepped mounting surface, defining the arrangement direction of the diverter plates as a first direction. In the first direction, the stepped mounting surface on a single adapter includes a kick surface corresponding to the number of diverter plates and / or diverter assemblies, and the corresponding ends of the diverter plates are detachably mounted on different kick surfaces by fasteners.

[0018] Furthermore, the column busbar crimping assembly also includes a flexible busbar connecting the column adapter and the column crimping component.

[0019] Furthermore, the column busbar crimping assembly also includes an adjustment bracket with an adjustment element threaded onto it for contacting the column busbar.

[0022] The beneficial effects of the current shunt device for starting aluminum electrolytic cells provided by this utility model are as follows: This utility model is a pioneering invention. By detachably connecting the two ends of each shunt plate and / or each shunt component to the horizontal adapter and the vertical adapter, when the deformation of any shunt plate is too large, only the corresponding shunt plate or shunt component needs to be replaced, without having to discard other shunt plates (shunt components), the horizontal pressing component, and the vertical pressing component at the same time, which can effectively reduce costs.

[0023] When using the current shunt device for starting the aluminum electrolytic cell in this utility model, firstly, use clamps to detachably connect the horizontal crimping member to the horizontal busbar, and detachably connect the column crimping member to the column busbar, thereby realizing the installation of the current shunt device for starting the aluminum electrolytic cell; then, start the cell normally; after the cell is started, remove the current shunt device for starting the aluminum electrolytic cell, and replace the corresponding shunt plate (shunt component) as needed.

[0034] To address the problems in the background technology, the core inventive concept of this utility model is to design each shunt segment as detachable, so that if any shunt segment is damaged, only the corresponding shunt segment needs to be replaced.

[0035] The present invention will be further described in detail below with reference to the embodiments.

[0036] Specific embodiment 1 of the current shunt device for starting aluminum electrolytic cells provided by this utility model:

[0037] like Figures 1-4As shown, in a preferred embodiment, the current shunting device 100 for starting the aluminum electrolytic cell includes a horizontal busbar crimping assembly, a column busbar crimping assembly, and at least two shunting plates 1. The horizontal busbar crimping assembly includes a horizontal crimping member 4 for detachable connection with the horizontal busbar 300 and a horizontal adapter connected to the horizontal crimping member 4. The column busbar crimping assembly includes a column crimping member 3 for detachable connection with the column busbar 500 and a column adapter connected to the column crimping member 3. The two ends of each shunting plate 1 are detachably connected to the horizontal adapter and the column adapter, respectively.

[0038] Among them, the column pressing component 3 and the horizontal pressing component 4 are pressing components commonly used in the prior art, such as pressing plates or pressing blocks; the number of diverter plates 1 can be two, three or more, and those skilled in the art can set the corresponding number of diverter plates 1 according to the actual diversion situation required during slot opening. Figure 3 The specific implementation shown has ten instances. Figure 5 The specific implementation shown comprises fourteen embodiments. Figure 7 The specific implementation methods shown are eight in total.

[0039] In other specific embodiments, the shunt 1 can also be a single unit, which can be replaced when the shunt 1 is damaged.

[0040] like Figure 1 As shown, the horizontal crimping member 4 is detachably connected to the horizontal busbar 300 of the previous aluminum electrolysis cell 200 via a horizontal clamp 400 (e.g., a U-shaped clamp), and the column crimping member 3 is detachably connected to the column busbar 500 of the next aluminum electrolysis cell 200 via a column clamp 600 (a π-type hanging plate clamp).

[0041] In use, firstly, the horizontal crimping component 4 is detachably connected to the horizontal busbar 300 using the corresponding clamps, and the column crimping component 3 is detachably connected to the column busbar 500; then, the slot is opened normally; after the slot is opened, the current shunt device 100 for opening the aluminum electrolysis cell is removed, and the corresponding shunt plate 1 is replaced as needed. Since both ends of each shunt plate 1 are detachably connected to the horizontal adapter and the column adapter, only the corresponding shunt plate 1 needs to be replaced when the deformation of any shunt plate 1 is too large, without having to discard other shunt plates 1, the horizontal crimping component 4, and the column crimping component 3 at the same time, which can effectively reduce costs.

[0042] The following combination Figures 2-4 The current shunt device 100 for starting the aluminum electrolytic cell is described in specific embodiment 1.

[0043] like Figures 2-4As shown, the horizontal adapter and the vertical adapter include a first adapter plate 10, which has a receiving groove 10-1. Both ends of each diverter 1 are located in the corresponding receiving groove 10-1, and the adapter plate and the diverter 1 are detachably connected by fasteners 2.

[0044] In a preferred embodiment, each diverter 1 has through holes on the portion of the diverter 1 located in the receiving groove 10-1 and on the first adapter plate 10. The fastener 2 is a double-ended screw that passes through the through holes on both the diverter 1 and the first adapter plate 10. Both ends of the double-ended screw are connected to nuts to achieve a detachable connection between the diverter 1 and the horizontal adapter or the column adapter. The structure is simple.

[0045] In other specific embodiments, the first adapter plate 10 is provided with both through holes and threaded holes. After the bolt passes through the through holes on the diverter plate 1 and the first adapter plate 10, it is threaded into the threaded holes. In this case, the first adapter plate 10 needs to be made of a material with high temperature resistance to avoid excessive deformation of the threaded holes due to heat, which would prevent the bolt from being removed.

[0046] like Figure 1 As shown, the side of the column busbar 500 that contacts the column crimping member 3 is inclined. To make the current shunting device 100 for opening the aluminum electrolytic cell suitable for column busbars 500 with various inclination angles, in a preferred embodiment, the column busbar crimping assembly also includes a flexible busbar (i.e., column flexible busbar 5) connecting the column adapter and the column crimping member 3. Because the flexible busbar is flexible, it can change the inclination angle of the column crimping member 3, so that the column crimping member 3 can make close contact with column busbars 500 with different inclination angles. This makes the current shunting device 100 for opening the aluminum electrolytic cell suitable for column busbars 500 with various inclination angles, reducing the number of current shunting devices 100 for opening the aluminum electrolytic cell on site and facilitating on-site management.

[0047] In other specific embodiments, the column busbar crimping assembly may not include the column flexible busbar 5. In this case, the current shunting device 100 for opening the aluminum electrolytic cell is only applicable to a specific column busbar 500, and it is necessary to prepare a variety of aluminum electrolytic cell opening current shunting devices 100 with different inclination angles of column crimping parts 3 on site.

[0048] In a preferred embodiment, the column busbar crimping assembly further includes an adjusting bracket 7. The adjusting bracket 7 can be fixed to the column adapter by bolts or welding. The adjusting bracket 7 has a threaded adjusting element for contacting the column busbar 500. The adjusting element can be a threaded part such as an adjusting screw or adjusting bolt 8, and its axis is perpendicular to the contact surface between the column busbar 500 and the adjusting element. In use, the height of the adjusting element can be adjusted by turning it to accommodate column busbars 500 of different heights.

[0049] Meanwhile, the adjusting component and adjusting frame 7 can further support the column adapter and the diverter plate 1 connected to the column adapter.

[0050] However, since the adjusting frame 7 is not flexible, the tilt angle of the adjusting component remains constant and it cannot adapt to column busbars 500 with different tilt angles.

[0051] In other specific embodiments, refer to Figures 5-8 As shown, the adjusting frame 7 and adjusting components can also be omitted, and the column adapter can be directly or indirectly supported by the column pressing component 3 (direct support when the column pressing component 3 is directly connected to the column adapter, and indirect support when the column pressing component 3 is indirectly connected to the column adapter through the column flexible busbar 5).

[0052] To facilitate the installation of the current shunting device 100 for starting the aluminum electrolytic cell, preferably, the horizontal busbar crimping assembly also includes a flexible busbar (i.e., a horizontal flexible busbar 6) connecting the horizontal adapter and the horizontal crimping member 4. In this case, even if there is a slight deviation in the installation position of the horizontal crimping member 4, it will not affect the normal installation and use of the current shunting device 100 for starting the aluminum electrolytic cell.

[0053] Of course, in other specific embodiments, the horizontal busbar crimping assembly may not include the horizontal flexible busbar 6, and the horizontal adapter and the horizontal crimping component 4 may be directly welded together. In this case, the current shunting device 100 for opening the aluminum electrolytic cell needs to be accurately positioned when installing it.

[0054] In the current shunt device 100 for starting an aluminum electrolytic cell, the horizontal adapter, the vertical adapter, the horizontal pressing component 4, and the vertical pressing component 3 have larger current-passing areas and smaller resistances, while the current shunt plate 1 has smaller current-passing areas and larger resistances. Therefore, the lifespan of the horizontal adapter, the vertical adapter, the horizontal pressing component 4, and the vertical pressing component 3 is naturally longer than that of the current shunt plate 1.

[0055] However, since the flexible busbar needs to be bent, its current-carrying area is limited. Therefore, in order to further improve the service life of the current shunt device 100 for starting the aluminum electrolytic cell, as a preferred embodiment, both the horizontal flexible busbar 6 and the vertical flexible busbar 5 are made of materials with low resistivity, while the current shunt plate 1 is made of materials with high resistivity, so as to extend the service life of the horizontal flexible busbar 6 and the vertical flexible busbar 5, and thus extend the service life of the entire current shunt device 100 for starting the aluminum electrolytic cell.

[0056] The materials that can be specifically selected for the current shunt device 100 for starting the aluminum electrolytic cell include steel, aluminum, copper, steel-aluminum composite material, steel-copper composite material, and copper-aluminum composite material.

[0057] To facilitate the hoisting of the current shunt device 100 for opening the aluminum electrolytic cell, as a preferred embodiment, the horizontal busbar crimping assembly and the column busbar crimping assembly further include a hoisting component 9 for use with the lifting device. The hoisting component 9 is connected to a corresponding adapter, such as... Figures 2-4 As shown, the lifting component 9 is a lug with lifting holes. The lug is fixed to the corresponding adapter by bolts, and the lugs on different adapters are welded to both ends of the reinforcing plate. The lifting component 9 can be used to easily lift the current shunt device 100 for opening the aluminum electrolytic cell.

[0058] In other specific embodiments, refer to Figures 5-8 As shown, the current shunt device 100 for lifting and opening the aluminum electrolytic cell may not include the lifting component 9. When lifting and installing the current shunt device 100 for lifting and opening the aluminum electrolytic cell, the lifting rope can be used to wrap around and fix the current shunt device 100 for lifting and opening the aluminum electrolytic cell.

[0059] Specific embodiment 2 of the current shunt device for starting aluminum electrolytic cells provided by this utility model:

[0060] The purpose of this embodiment is to provide a current shunt device for starting an aluminum electrolytic cell with different adapters.

[0061] In reference Figures 1-4 On the basis of, such as Figures 5-6 As shown, the main difference between this embodiment and specific embodiment 1 is that in specific embodiment 1, the adapter includes a first adapter plate 10, while in this embodiment, the adapter includes a main body and a conductive strip 11.

[0062] The horizontal adapter and the vertical adapter include a main body and a plurality of conductive strips 11 connected to the main body. Each conductive strip 11 includes a contact portion for conductive contact with the current divider 1. The arrangement direction of the current divider 1 is defined as a first direction. The contact portions are evenly spaced along the first direction. A receiving gap is formed between two adjacent contact portions to accommodate the end of the current divider 1. The contact portions are detachably connected to the current divider 1 by fasteners 2.

[0063] The conductive strip 11 is welded to the main body at the end furthest from the contact portion. The fastener 2 can be a bolt or a double-ended screw. The fastener 2 passes through the through holes on the corresponding shunt plate 1 and the through holes on the contact portion and is connected with a nut to achieve a detachable connection between the adapter and the shunt plate 1.

[0064] In the above specific embodiments, the number of current shunt plates 1 is relatively small, and the maximum current that the current shunt device 100 for starting the aluminum electrolytic cell can withstand is relatively small.

[0065] In a preferred embodiment, in the first direction, contact portions are located on both sides of the main body, and a receiving gap for accommodating the end of the shunt plate 1 is formed between the main body and the adjacent contact portions. An end plate 12 is provided on the outer side of the outermost contact portion, and a receiving gap for accommodating the end of the shunt plate 1 is also formed between the end plate 12 and the outermost contact portion. The end plate 12, contact portions, shunt plate 1, and main body are detachably connected by fasteners 2. In this case, the number of shunt plates 1 is increased, enabling it to withstand a larger current.

[0066] At this time, the fastener 2 can be a bolt with a threaded hole on its main body. The bolt passes through the corresponding holes on the end plate 12, the contact part, and the diverter plate 1 and is threadedly connected to the threaded hole; or, the fastener 2 can be a double-ended screw with a nut connected to both ends of the double-ended screw.

[0067] Specific embodiment 3 of the current shunting device for starting aluminum electrolytic cells provided by this utility model:

[0068] The purpose of this embodiment is to provide another current shunt device for starting an aluminum electrolytic cell with different adapters.

[0069] In reference Figures 1-4 On the basis of, such as Figures 7-8 As shown, the main difference between this embodiment and specific embodiment 1 is that in specific embodiment 1, the adapter includes a first adapter plate 10, while in this embodiment, the adapter includes a second adapter plate 13.

[0070] The horizontal adapter and the vertical adapter include a second adapter plate 13. The second adapter plate 13 includes a stepped mounting surface with a kick surface 13-2 and a tread surface 13-1. The arrangement direction of the diverter 1 is defined as a first direction. In the first direction, the stepped mounting surface on a single second adapter plate 13 (or a single adapter) includes the same number of kick surfaces 13-2 as the number of diverter 1. The corresponding ends of each diverter 1 are detachably mounted on different kick surfaces 13-2 by fasteners 2.

[0071] Specifically, the fastener 2 can be a bolt, and the second adapter plate 13 is provided with a threaded hole. The bolt passes through the corresponding through hole on the diverter plate 1 and is threadedly connected to the threaded hole. Alternatively, the fastener 2 can be a double-ended screw, which passes through the through hole on the diverter plate 1 and the second adapter plate 13, and nuts are connected to both ends of the double-ended screw.

[0072] Specific embodiment 4 of the current shunt device for starting aluminum electrolytic cells provided by this utility model:

[0073] The purpose of this embodiment is to provide a current shunting device for starting an aluminum electrolytic cell with two adapters having different structures.

[0074] Reference Figures 1-8 As shown, the main difference between this embodiment and specific embodiments 1-3 is that in specific embodiments 1-3, the structures of the horizontal adapter and the vertical adapter are basically the same, while in this embodiment, the structures of the horizontal adapter and the vertical adapter are completely different, referring to... Figures 2-8 As shown, for example, the horizontal adapter and the vertical adapter respectively include a first adapter plate 10 and a second adapter plate 13; of course, one adapter may include a conductive strip 11 and a main body, and the other adapter may include a first adapter plate 10 or a second adapter plate 13, which will not be listed in detail here.

[0075] Specific embodiment 5 of the current shunt device for starting aluminum electrolytic cells provided by this utility model:

[0076] The purpose of this embodiment is to provide a current shunt device for starting an aluminum electrolytic cell, in which the shunt plates are fixedly connected to form a shunt assembly.

[0077] Reference Figures 1-8 As shown, the main difference between this embodiment and specific embodiments 1 to 4 is that in specific embodiments 1 to 4, each diverter 1 is arranged independently, while in this embodiment, all diverter pieces are used to form at least one diverter assembly. The diverter assembly includes at least two fixedly connected diverter pieces, and the two ends of the diverter assembly are detachably connected to the horizontal adapter and the vertical adapter, respectively.

[0078] When there are two shunt segments 1, the two shunt segments 1 form a shunt component; when there are four shunt segments 1, the shunt segments 1 are grouped in pairs to form two shunt components, or the four shunt segments 1 together form a shunt component, and so on.

[0079] The specific connection method can be: the two diverter plates 1 are fixedly connected by a connecting plate, and both diverter plates 1 are welded to the connecting plate; or, the two diverter plates 1 are directly fixedly connected by a double-ended screw and four nuts, with the two nuts clamping one diverter plate 1.

[0080] The diversion component is detachably connected to the horizontal adapter and the vertical adapter through the diversion piece 1. Therefore, the specific form of the detachable connection between the diversion component and the horizontal adapter and the vertical adapter is the same as the specific form of the detachable connection between the diversion piece 1 and the horizontal adapter and the vertical adapter, and will not be described again here.

[0081] Specific embodiment 6 of the current shunting device for starting aluminum electrolytic cells provided by this utility model:

[0082] The purpose of this embodiment is to provide a current shunting device for starting an aluminum electrolytic cell, which includes both a current shunting element and a current shunting assembly.

[0083] Reference Figures 1-8 As shown, the main difference between this embodiment and specific embodiments 1 to 5 is that: in specific embodiments 1 to 4, each shunt piece 1 is arranged independently; in specific embodiment 5, the shunt pieces 1 are all used to form a shunt assembly; while in this embodiment, both a shunt assembly and independently arranged shunt pieces 1 are included.

[0084] In this embodiment, there are at least three diverter plates, of which at least two diverter plates 1 are fixedly connected to form a diverter assembly. The number of diverter assemblies is at least one, wherein at least one diverter plate 1 is arranged independently. The two ends of the independently arranged diverter plate 1 are detachably connected to the horizontal adapter and the vertical adapter, respectively. The two ends of the diverter assembly are detachably connected to the horizontal adapter and the vertical adapter, respectively.

[0085] When there are three shunt segments 1, two shunt segments 1 form a shunt assembly, and the remaining shunt segments 1 are independently arranged; when there are four shunt segments 1, two shunt segments 1 form a shunt assembly, and the remaining shunt segments 1 are independently arranged; or, three shunt segments 1 form a shunt assembly, and the remaining shunt segments 1 are independently arranged; when there are five shunt segments 1, four shunt segments 1 are grouped in pairs to form two shunt assemblies, and the remaining shunt segments 1 are independently arranged. This list will not be exhaustive.

[0086] It should be noted that in a single diversion assembly, only any two diversion pieces 1 may be detachably connected to the horizontal adapter and the vertical adapter. For example, when the diversion assembly includes at least three diversion pieces 1, the two outermost diversion pieces 1 may be detachably connected to the horizontal adapter and the vertical adapter, while the diversion piece 1 in the middle may or may not be connected to the horizontal adapter and the vertical adapter.

[0087] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
