Technical Field

[0001] This utility model relates to the field of aluminum electrolysis production technology, and in particular to a balance fork for replacing residual electrodes in aluminum electrolysis. Background Technology

[0002] The residual electrode in the prebaked electrolytic cell needs to be replaced after a certain period of use. The residual electrode will be gradually consumed during use, resulting in a decrease in its conductivity and affecting the normal operation of the electrolytic cell. During electrolysis, the residual electrode will become thinner due to oxidation, resulting in uneven current distribution and affecting electrolysis efficiency. Regularly replacing the residual electrode can ensure the stable operation of the electrolytic cell and efficient production.

[0003] Chinese patent discloses a balancing fork for replacing aluminum electrolytic electrode residues (application number 202220711946.9), comprising a horizontal bar and a vertical bar. The vertical bar is vertically positioned at the center of the horizontal bar. Two balancing components are mounted on the horizontal bar, symmetrical about the vertical bar. Each balancing component includes a first side bar and a second side bar. The first side bar has an adapter seat, and a surrounding bar is rotatably connected to the adapter seat. The second side bar has a protruding post, and the other end of the surrounding bar is inserted into the protruding post, thus forming a rectangular frame with the first side bar, the second side bar, the surrounding bar, and the horizontal bar. The purpose of this invention is to provide a balancing fork for replacing aluminum electrolytic electrode residues, aiming to solve the problem of imbalance and relative swaying that occurs when lifting two residual carbon electrode blocks during electrode replacement.

[0004] The aforementioned disclosed patents have the following problems when used:

[0005] The balance fork limits the carbon block by using side bars and a retaining bar. However, since the side bars are fitted onto the crossbar through a sleeve connected to their bottom, and the sleeve is fixed to the crossbar by screws and screw holes, the range of use of the balance fork is limited. It may become loose and unstable during use, resulting in low stability. Utility Model Content

Detailed Implementation

[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] The purpose of this invention is to provide a balance fork for replacing aluminum electrolytic electrode residues, so as to solve the problems existing in the prior art, improve the scope of application, and make the electrode residues more stable and safer during transportation.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-4 As shown, this embodiment provides a balance fork for replacing aluminum electrolytic electrode residue, including a crossbar 1 and a vertical bar 2. The vertical bar 2 is vertically positioned at the center of the crossbar 1. Two balance components are provided on the crossbar 1, symmetrical about the vertical bar 2. Each balance component includes a first side bar 3 and a second side bar 4. An adapter seat 5 is provided on the first side bar 3, and a retaining rod 6 is rotatably connected to the adapter seat 5. A protrusion 7 is provided on the second side bar 4, and the other end of the retaining rod 6 is inserted into the protrusion 7, thereby forming a rectangular frame with the first side bar 3, the second side bar 4, the retaining rod 6, and the crossbar 1. A rod sleeve 8 is provided at the bottom of both the first side bar 3 and the second side bar 4. A round hole is opened at the bottom of the rod sleeve 8, which is fitted onto the crossbar 1 and can be locked onto the crossbar 1 by screws 9. Multiple screw holes 38 are provided at intervals on the crossbar 1, symmetrical about the vertical bar 2. It also includes... The fixing assembly includes a fixing frame 10, a bidirectional screw 11, a driving device, a threaded block 12, and a clamping device 13. The fixing frame 10 is fixed to the crossbar 1. The bidirectional screw 11 is rotatably connected to the fixing frame 10 and driven to rotate by the driving device. The bidirectional screw 11 has two threaded sections 14 with opposite directions of rotation. Each threaded section 14 is threaded with a threaded block 12. The two threaded blocks 12 are symmetrical about the vertical bar 2 and are slidably disposed on the upper surface of the crossbar 1. Each second side bar 4 is connected to a clamping device 13. The clamping device 13 can slide on the second side bar 4 in a direction parallel to the crossbar 1. One end of the clamping device 13 is located on the side of the second side bar 4 away from the threaded block 12, and the other end is disposed opposite to the threaded block 12. The threaded block 12 can move along the threaded section 14 to squeeze the clamping device 13 opposite to it.

[0031] In use, the anode carbon block is inserted between the first side rod 3 and the second side rod 4. The anode carbon block is limited by the surrounding rod 6. The bidirectional screw 11 is driven to rotate by the drive device, thereby moving the threaded block 12 closer to the clamping device 13. The threaded block 12 squeezes the clamping device 13, and the clamping device 13 further squeezes and contacts the anode carbon block, thus squeezing and limiting the anode carbon block. This makes the anode carbon blocks on both sides more stable and safer during transportation.

[0032] In this embodiment, the clamping device 13 includes a connecting rod 15, a stop block 16, a contact plate 17, and a spring 18. The connecting rod 15 passes through the second side rod 4. The stop block 16 is fixed to the end of the connecting rod 15 away from the threaded block 12. The contact plate 17 is fixed to the end of the connecting rod 15 near the threaded block 12, and the contact plate 17 is arranged opposite to the threaded block 12. The spring 18 is sleeved on the connecting rod 15, and its two ends abut against the contact plate 17 and the second side rod 4, respectively. When the threaded block 12 presses against the contact plate 17, it compresses the spring 18 and simultaneously presses against the anode carbon block through the stop block 16. When the threaded block 12 moves back to its original position, the stop block 16 returns to its original position under the action of the spring 18, without affecting the next use.

[0033] In this embodiment, both ends of the bidirectional screw 11 are fixedly provided with limiting plates 19, which can prevent the threaded block 12 from disengaging from the bidirectional screw 11.

[0034] In this embodiment, the driving device includes a transmission rod 20, a driving wheel 21, and a driven wheel 22. The transmission rod 20 is rotatably connected to the fixed frame 10, and a knob 23 is fixedly mounted on the transmission rod 20. The driving wheel 21 is fixed to the transmission rod 20, and the driven wheel 22 is fixed to the bidirectional screw 11 and meshes with the driving wheel 21. Rotating the knob 23 drives the bidirectional screw 11 to rotate, making adjustment convenient and quick. The driving wheel 21 and the driven wheel 22 are bevel gears, ensuring reliable transmission and high transmission efficiency.

[0035] When using the fixed assembly, the anode carbon block is first inserted between the first side rod 3 and the second side rod 4. The anode carbon block is limited by the surrounding rod 6. Then, the knob 23 is turned to drive the transmission rod 20 to rotate. The transmission rod 20 drives the drive wheel 21 to rotate, which in turn drives the driven wheel 22 to drive the bidirectional screw 11 to rotate. The rotation of the bidirectional screw 11 causes the threaded block 12 to contact the contact plates 17 on both sides. While the contact plates 17 are being squeezed, the spring 18 is compressed, and the abutment block 16 can contact the anode carbon block to squeeze and limit it. This makes the anode carbon blocks on both sides more stable during the transfer process. After the transfer is completed, the knob 23 is reversed, and the abutment block 16 is reset under the action of the spring 18. This will not affect the reuse of the balance fork, improve the stability during use, and expand the application range of the balance fork.

[0036] This embodiment also includes a vertical rod adjustment assembly, which comprises a threaded cylinder 24, a screw 25, a storage cylinder 26, a fixing block 27, and a locking assembly 28. The threaded cylinder 24 is fixed to the bottom of the vertical rod 2, with its lower end extending into the storage cylinder 26. The fixing block 27 is fixed inside the storage cylinder 26, and the lower end of the screw 25 is fixed to the fixing block 27. The upper end of the screw 25 is threadedly connected to the threaded cylinder 24. The locking assembly 28 is used to lock the storage cylinder 26 and the threaded cylinder 24. By setting the vertical rod adjustment assembly, the extension length of the vertical rod 2 can be adjusted when using the balance fork, thereby expanding the applicability of the balance fork. This allows the operator to adjust the length of the vertical rod 2 according to work requirements, keeping the operator away from high-temperature residue and ensuring high safety.

[0037] In this embodiment, the storage tube 26 is fixedly fitted with an anti-slip sleeve 29 to improve the stability of gripping.

[0038] When using the vertical rod adjustment assembly, first hold the anti-slip sleeve 29 and rotate it. The anti-slip sleeve 29 drives the storage cylinder 26 to rotate. Under the action of the fixing block 27 inside the storage cylinder 26, the rotation of the storage cylinder 26 drives the screw 25 to rotate. The rotation of the screw 25 further drives the threaded cylinder 24 to move, causing the threaded cylinder 24 to gradually move outward from the storage cylinder 26, thereby realizing the length adjustment of the vertical rod 2. After the adjustment is completed, the length of the vertical rod 2 is locked by the locking assembly 28 to avoid inconvenience during use. After use, the threaded cylinder 24 can be retracted into the storage cylinder 26 for easy storage, saving space and enhancing practicality.

[0039] In this embodiment, a limiting block 30 is fixedly provided on the lower end side wall of the threaded cylinder 24, and a limiting protrusion 31 corresponding to the limiting block 30 is fixedly provided on the upper end inner wall of the receiving cylinder 26. The limiting protrusion 31 can limit the limiting block 30 and prevent the threaded cylinder 24 from falling out of the receiving cylinder 26.

[0040] In this embodiment, the locking assembly 28 includes a handwheel 32, a connecting screw 33, a movable frame 34, and a locking block 35. The connecting screw 33 inserts inward into the storage cylinder 26 and is threadedly connected to the storage cylinder 26. The outward end of the connecting screw 33 is fixedly connected to the handwheel 32, and the inward end is rotatably connected to the movable frame 34. The connecting screw 33 and the movable frame 34 are fixed relative to each other in the axial direction. The locking block 35 is fixed to the end of the movable frame 34 facing away from the connecting screw 33 and is located on the outside of the threaded cylinder 24. By rotating the handwheel 32, the locking block 35 can be moved closer to or away from the threaded cylinder 24, thereby locking or unlocking the threaded cylinder 24. The structure is simple and the operation is convenient and quick.

[0041] In this embodiment, a plurality of anti-slip protrusions 36 are fixedly provided on the surface of the locking block 35 facing the threaded cylinder 24 to improve the locking effect.

[0042] When using the locking assembly 28, rotating the handwheel 32 drives the connecting screw 33 to rotate, which in turn drives the movable frame 34 to move. The movable frame 34 pushes the locking block 35 to contact the surface of the threaded cylinder 24, thereby preventing the threaded cylinder 24 from moving further. The anti-slip protrusions 36 on the surface of the locking block 35 further increase the friction between the threaded cylinder 24 and the locking block 35, improving the locking effect of the threaded cylinder 24 and enhancing the stability of use.

[0043] In this embodiment, the connecting screw 33 is rotatably connected to the movable frame 34 through a bearing. The surface of the storage cylinder 26 facing the threaded cylinder 24 is provided with a storage groove 37. The movable frame 34 can be moved and stored in the storage groove 37 to avoid the movable frame 34 affecting the use of the threaded cylinder 24.

[0044] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
