Description

Technical Field

[0001] This utility model relates to the field of conductive component processing technology, specifically to an auxiliary filler tool for assembling cathode carbon blocks. Background Technology

[0002] In the aluminum electrolysis production process, the cathode rod, as a key conductive component, is typically composed of a cathode carbon block and a steel rod. The traditional assembly process is as follows:

[0003] Structural design: Two mounting slots are machined on the cathode carbon block, and two steel rods are embedded into the two mounting slots accordingly.

[0004] Gap filling: Since there is an assembly gap between the steel rod and the installation slot, it is necessary to fill it with paste (such as cathode paste or pig iron) to ensure conductivity and mechanical stability.

[0005] The existing filling process for the paste is as follows:

[0006] The operator directly poured the paste into the gap;

[0007] A vibratory pressing rod is inserted into the gap to compact the paste section by section.

[0008] Due to the limited fluidity of the paste, it needs to be added in small amounts multiple times and repeatedly vibrated and compacted to prevent uneven filling or the formation of air pockets.

[0009] However, the filling process of this paste requires multiple fillings and vibrations, resulting in cumbersome operation and low assembly efficiency. Utility Model Content

[0010] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary filling tool for assembling cathode carbon blocks, so as to solve the problem that the filling paste process requires multiple filling and vibration, resulting in cumbersome operation and low assembly efficiency.

[0011] To achieve the above objectives, this utility model adopts the following technical solution: a cathode carbon block assembly auxiliary filler tool, assembled between the cathode carbon block and two steel rods, comprising:

[0012] A support frame, which is fixedly sleeved on the outside of the cathode carbon block and seals the point where the steel rod passes through the mounting slot on the cathode carbon block.

[0013] The outer baffle, after being attached to the support frame and the top of the cathode carbon block, forms two storage tanks. The gap formed between the two mounting through slots and the corresponding steel rods is connected to the bottom of the two storage tanks.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This cathode carbon block assembly auxiliary filler tool simultaneously assembles a support frame and an outer baffle during the assembly of the cathode carbon block and two steel rods. The support frame provides support to the outer baffle and also seals the point where the steel rods exit through the mounting slot on the cathode carbon block. The outer baffle, support frame, and cathode carbon block work together to form two storage tanks. The paste is then added to the two storage tanks all at once. Next, a vibrating pressing rod is used to repeatedly vibrate the paste in the storage tanks to guide the paste into the gap formed between the mounting slot and the corresponding steel rod for compaction. This simplifies the operation steps, improves the assembly efficiency of the cathode carbon block and the two steel rods, and reduces waste caused by paste overflowing during the assembly of the cathode carbon block.

Detailed Implementation

[0021] The present invention will be further described in detail below through specific embodiments:

[0022] like Figure 1 As shown in the figure, this utility model embodiment proposes an auxiliary filler tool for assembling a cathode carbon block, which is assembled between the cathode carbon block 1 and two steel rods 2. It includes a support frame 3 and an outer baffle 4. The support frame 3 is fixedly sleeved on the outside of the cathode carbon block 1 and seals the point where the steel rods 2 pass through the mounting slots on the cathode carbon block 1. The outer baffle 4 overlaps the support frame 3 and the top of the cathode carbon block 1 to form two storage troughs 5. The gap formed between the two mounting slots and the corresponding steel rods 2 is connected to the bottom of the two storage troughs 5.

[0023] This cathode carbon block assembly auxiliary filler tool simultaneously assembles the support frame 3 and the outer baffle 4 during the assembly of the cathode carbon block 1 and the two steel rods 2. The support frame 3 provides support for the outer baffle 4 and also seals the point where the steel rods 2 pass through the mounting slot on the cathode carbon block 1. The outer baffle 4, the support frame 3, and the cathode carbon block 1 cooperate to form two storage tanks 5. The paste is then added to the two storage tanks 5 in one go. Next, a vibrating pressing rod is used to repeatedly vibrate the paste in the storage tanks 5 to guide the paste in the storage tanks 5 into the gap formed between the mounting slot and the corresponding steel rods 2 for compaction. This simplifies the operation steps, improves the assembly efficiency of the cathode carbon block 1 and the two steel rods 2, and reduces the waste caused by the paste overflowing from the cathode carbon block 1 during the assembly process.

[0024] To better understand this solution, the structure of support frame 3 and outer retaining frame 4 will be optimized below.

[0025] First is the outer baffle 4.

[0026] like Figure 2 As shown, according to another embodiment of the present invention, the cathode carbon block assembly auxiliary filler tool, wherein the outer baffle 4 includes an end plate 41, a side plate 42 and a partition plate 43, and there are two end plates 41.

[0027] The side plates 42 are two in number and are connected between the two end plates 41 to form an accommodating space; the partition 43 is connected between the two end plates 41 and located between the two side plates 42 to divide the accommodating space into two cavities.

[0028] In this embodiment, the two end plates 41, the two side plates 42, and the partition plate 43 serve as the main structure of the outer baffle 4. After assembly, the two cavities form two storage tanks 5. The storage tanks 5 store a large amount of paste at one time, and during the operation of the vibrating pressing rod, the paste is prevented from overflowing and causing waste.

[0029] Specifically, the end plates 41 are all in the shape of an isosceles trapezoid.

[0030] During the process of the vibrating pressing rod pressing the paste into the gap, the side plate 42 is subjected to a relatively large impact force. In order to improve the structural strength of the side plate 42, each side plate 42 is equipped with a reinforcing structure. Each reinforcing structure includes a connecting plate 44, which is connected between the two end plates 41 and is also connected to the side of the corresponding side plate 42 that is outside the receiving space.

[0031] Here, a connecting plate 44 is used to connect the two end plates 41 and the corresponding side plates 42 to enhance the structural strength of the side plates 42 and the overall structural strength of the outer frame 4.

[0032] To further improve the structural strength of the side plate 42, the reinforcing structure also includes ribs 45. There are multiple ribs 45, and they are all connected to the connecting plate 44 and the corresponding side plate 42. The multiple ribs 45 are distributed at intervals along the length direction of the corresponding side plate 42.

[0033] In this embodiment, the rib plate 45 is triangular.

[0034] To facilitate the hoisting and assembly of the outer retaining frame 4, the outer retaining frame 4 is connected to two hoisting rings 46, which are distributed on different sides of the two side plates 42. Each hoisting ring 46 is U-shaped, and its two ends are fixedly connected to the end plate 41, side plate 42, and / or rib plate 45 of the outer retaining frame 4.

[0035] Inside the factory, a gantry crane is used to connect to two lifting rings 46 via hooks. Due to the arrangement of the two lifting rings 46, the outer frame 4 can be stably lifted for assembly or disassembly.

[0036] Next is support frame 3.

[0037] like Figure 2 As shown, according to another embodiment of the present invention, the cathode carbon block assembly auxiliary filler tool includes a support frame 3 comprising two support end plates 31, with the cathode carbon block 1 sandwiched between the two support end plates 31. Each support end plate 31 has a positioning notch for two steel rods 2 to pass through and fit with a clearance. Each support end plate 31 is connected to two separately arranged connecting ears 32. The two connecting ears 32 arranged opposite to each other on the two support end plates 31 are detachably connected by a locking member 33.

[0038] In this embodiment, the support frame 3 is mainly composed of support end plates 31, connecting ears 32 and locking members 33. The two support end plates 31 are distributed at both ends of the cathode carbon block 1 and are both engaged with the two steel rods 2. The two locking members 33 are respectively connected between the corresponding two connecting ears 32, thereby connecting the two support end plates 31 into a whole to support the outer frame 4 and seal the point where the steel rod 2 passes through the mounting groove on the cathode carbon block 1.

[0039] Each of the connecting lugs 32 has an installation notch, and each locking member 33 includes a connecting rod 331. The two ends of the connecting rod 331 pass through the installation notches of the two matching connecting lugs 32 and are threadedly connected to a locking nut 332 that abuts against the corresponding connecting lug 32.

[0040] In this embodiment, the mounting notch is formed at the top of the corresponding connecting lug 32 so that both ends of the connecting rod 331 can be inserted into the mounting notch of the two corresponding connecting lugs 32. Then, locking nuts 332 are threaded onto both ends of the connecting rod 331 to abut against the corresponding connecting lugs 32, thus ensuring that the two support end plates 31 are stably assembled on both ends of the cathode carbon block 1. Here, the connecting rod 331 can be a screw. To improve the stability of the locking nut 332 after connection, a washer can be fitted onto the connecting rod 331 to abut against the connecting lug 32 and the locking nut 332.

[0041] In order to facilitate the hoisting of the support end plate 31 during the assembly process, two hoisting columns 34 are connected to the outer side of each support end plate 31 at intervals. A hoisting rope is fixedly tied between the two hoisting columns 34, and then the gantry crane can be used for hoisting.

[0042] To improve the assembly accuracy of the outer retaining frame 4 and the support frame 3, such as Figure 2 As shown, according to another embodiment of the present invention, the cathode carbon block assembly auxiliary filler tool is provided with a plurality of positioning structures 6 between the outer baffle 4 and the support frame 3. Each positioning structure 6 includes a positioning block 61 and a positioning groove 62. The positioning block 61 is connected to the bottom of the outer baffle 4 or the top of the support frame 3. The positioning groove 62 is opened on the top of the support frame 3 or the bottom of the outer baffle 4 and is used for the positioning block 61 to be embedded for positioning.

[0043] In this embodiment, there are two positioning structures 6, which are distributed on both sides of the top of the support frame 3. Specifically, a positioning block 61 is connected to the middle position of the top of each support end plate 31, and a positioning groove 62 is opened at the middle position of the bottom of each end plate 41.

[0044] During the hoisting process, ensure that the two positioning blocks 61 are embedded into the two positioning slots 62 in a one-to-one correspondence to ensure that the outer baffle 4 has high installation accuracy, which is conducive to the smooth filling of the paste.

[0045] The assembly process for this cathode carbon block assembly auxiliary filler tool is as follows:

[0046] The two support end plates 31 are arranged one-to-one on both ends of the cathode carbon block 1, and then the two locking parts 33 are used to stably assemble the two support end plates 31 on both ends of the cathode carbon block 1 to complete the assembly of the support frame 3.

[0047] Then, the two steel rods 2 are assembled into the two mounting slots one by one, and the ends of the steel rods 2 are inserted into the positioning notches on the support end plate 31 one by one.

[0048] Then, the outer bracket 4 is hoisted and assembled onto the top of the support frame 3 to complete the assembly;

[0049] Next, add paste into the storage tank 5, and then operate the vibrating pressing rod to press the paste into the gap for compaction.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
