Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis anode busbars, in particular to a monitoring device for the deviation of aluminum electrolysis anode busbars. Background Art

[0002] In the current large-scale electrolytic aluminum production, the anode busbar is not only a channel for high-intensity current, but also plays the role of suspending and fixing multiple groups of anodes. The pre-baked anodes that are replaced regularly are fixed on the anode busbar by small box clamps. The anode busbar is installed on the lifting mechanism by hanging, and the lifting mechanism drives the anode busbar to rise or fall. In normal electrolytic production, due to the continuous consumption of anodes, extinguishing effects and aluminum tapping operations, the position of the anode busbar needs to rise and fall continuously. The anode lifting device has a certain activity gap, and long-term frequent rise and fall can easily cause the anode busbar to shift; at the same time, due to the different positions of the anode replacement, the thickness of the crust covering the upper part of the anode carbon block is uneven, resulting in uneven force on the anode busbar during the rise and fall, which also causes the anode busbar to shift. When the anode busbar shifts, it must be corrected, otherwise it will cause uneven current distribution and voltage fluctuations. Long-term operation in this state may cause irregular furnace of the electrolytic cell and unstable technical indicators, resulting in greater economic losses.

[0003] At present, the monitoring method of the anode busbar is to first select the ground or a certain part of the electrolytic cell as the reference point, then use the wire to measure the height, and use the height difference to determine the offset. This operation method is relatively cumbersome and requires the staff to repeatedly pull the wire. At the same time, since the tightness of the manual wire and the verticality with the large busbar are difficult to judge, it is easy to cause large errors. Therefore, it is necessary to propose a monitoring device for the offset of the aluminum electrolytic anode busbar to solve the above-mentioned problems. Utility Model Content

[0008] In order to improve the stability of the expansion and contraction of the compression spring, as a preferred monitoring device for the deviation of the large busbar of the aluminum electrolysis anode of the utility model, the bottom side of the inner wall of the frame is fixedly connected with a guide rod which is sleeved inside the compression spring and passes through the sliding block, and the other end of the guide rod extends to the interior of the cylinder.

[0009] In order to facilitate the placement of tools such as recording pens and notebooks, and to record the monitored values, as a preferred monitoring device for the large busbar deviation of aluminum electrolysis anodes of the utility model, the upper end of the horizontal plate is fixedly connected with a placement frame.

[0010] In order to facilitate the driving of the screw rod to rotate, as a preferred monitoring device for the large busbar deviation of aluminum electrolysis anodes of the utility model, a motor is installed on the upper end of the connecting plate, and the output end of the motor passes through the connecting plate and is fixedly connected to the screw rod.

[0011] In order to facilitate the rotation of the four leveling screws, as a preferred monitoring device for the deviation of the large busbar of an aluminum electrolysis anode of the utility model, the upper ends of the four leveling screws are fixedly connected with knobs.

[0012] In order to prevent the sliding block from escaping from the interior of the frame, as a preferred monitoring device for the deviation of the large busbar of an aluminum electrolysis anode of the utility model, the right end of the sliding block is fixedly connected with a baffle extending through the interior of the slot and located above the pointer.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The horizontal plate is adjusted to a horizontal state by rotating four leveling screws and observing the level bubble, and then the contact is moved upward and contacts one end of the bottom side of the aluminum electrolytic anode busbar.

While the frame 6 continues to move upward, the compression spring 8 is compressed by the reaction force, and the scale of the pointer 12 pointing to the scale line 13 changes until the pointer 12 and the scale line 13 are at the zero scale. Correspondingly, at this time, the screw rod 4 stops rotating, and the zero scale position pointed by the pointer 12 is used as the reference position. When the offset of multiple positions of the large busbar is to be monitored, the device is moved to the position to be monitored, and then the contact 10 is brought into contact with the bottom side of the position to be monitored, and the position of the pointer 12 is observed. If the pointer is above the zero scale, the large busbar at the monitored position is offset upward, otherwise it is offset downward, and the specific offset value is recorded, thereby further achieving the effect of simple operation, and the contact 10 is always kept perpendicular to the horizontal plate 1, thereby achieving the effect of improving monitoring accuracy.

[0032] As a technical optimization solution of the present invention, a baffle 20 extending through the inside of the slot 11 and located above the pointer 12 is fixedly connected to the right end of the sliding block 7 .

[0033] In this embodiment, a baffle 20 is provided to prevent the sliding block 7 from being separated from the interior of the frame 6 .

[0034] Working principle: First, rotate the four leveling screws 14 respectively, and cooperate with the observation level bubble 15, so that the horizontal plate 1 can be adjusted to the horizontal level, and then the motor 19 drives the screw rod 4 to rotate, and then drives the lifting block 5 to move upward, and at the same time drives the frame 6, the sliding block 7, the cylinder 9 and the contact 10 to move upward, so that the contact 10 can contact one end of the bottom side of the aluminum electrolysis anode busbar. While the frame 6 continues to move upward, the compression spring 8 is compressed by the reaction force, and the scale of the pointer 12 pointing to the scale line 13 changes until the pointer 12 and the scale line 13 are zero. The scale corresponds to that, at this time, the screw rod 4 stops rotating, and the zero scale position pointed by the pointer 12 is used as the reference position. When the offset of multiple positions of the large busbar needs to be monitored, the device is moved to the position to be monitored, and then the contact 10 is brought into contact with the bottom side of the position to be monitored, and the position of the pointer 12 is observed. If the pointer is above the zero scale, the large busbar at the monitored position is offset upward, otherwise it is offset downward, and the specific offset value is recorded, thereby further achieving the effect of simple operation, and the contact 10 is always kept perpendicular to the horizontal plate 1, thereby achieving the effect of improving monitoring accuracy.
