Description

Technical Field

[0001] This utility model relates to the technical field of horizontal position adjustment device for the upper busbar of an aluminum electrolysis cell, and particularly to a horizontal position adjustment device for the upper busbar of an aluminum electrolysis cell. Background Technology

[0002] The upper busbar of the aluminum electrolysis cell serves as the overall power supply unit for the positive electrode of each cell in the aluminum electrolysis reaction, and is a crucial component of the reaction. In a 200kA aluminum electrolysis cell, this power supply unit supplies power to 24 groups of anode carbon blocks. Because the entire aluminum electrolysis series uses an electrical series power supply structure, the upper busbar inlet is powered by a single-sided busbar column. This directly results in the upper busbar of the aluminum electrolysis cell being subjected to lateral thrust from the single-sided busbar column for extended periods, causing horizontal displacement.

[0003] The horizontal position of the upper busbar in a normally operating online aluminum electrolytic cell is limited by the positions of the 24 sets of anode carbon block groups at the output end. Horizontal deviation is relatively minor. When replacing anode carbon block groups online, only one group is replaced; the positions of the remaining 23 sets of anode carbon block groups remain unchanged. Therefore, the horizontal position of the upper busbar in an online aluminum electrolytic cell does not require adjustment.

[0004] During the overhaul of the offline aluminum electrolytic cell, the horizontal position of the upper busbar is significantly offset due to the absence of the positional constraints imposed by the 24 sets of anode carbon blocks at the output end, and is subject to the lateral thrust of the single-sided power supply busbar column. If horizontal adjustment is not performed before the installation of the 24 sets of anode carbon blocks, serious consequences will occur after the overhaul, including uneven current distribution within the aluminum electrolytic cell, increased anode carbon block group effects, and reduced operating efficiency of the aluminum electrolytic cell.

[0005] Currently, the method for addressing the horizontal misalignment of the upper busbar in aluminum electrolytic cells is still the same: acceptance-inspection-discovery-adjustment after major overhaul. This not only fails to prevent problems beforehand but also leaves the entire overhaul quality to the final acceptance step, which no longer meets the requirements for full-process supervision and control of overhaul quality. Furthermore, the acceptance work after the overhaul is carried out inside the electrolysis plant. Adjusting the upper busbar requires using two sets of ultra-thin hydraulic jacks and four sets of mechanical jacks in a strong magnetic field environment. After adjustment, high-temperature refractory bricks must be placed between the upper busbar and the upper shell of the aluminum electrolytic cell to fix its position. The adjustment process is cumbersome and requires at least three people to work simultaneously. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a device for adjusting the horizontal position of the upper busbar of an aluminum electrolysis cell.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A device for adjusting the horizontal position of the upper busbar of an aluminum electrolysis cell includes:

[0009] The fixing mechanism is located at the top of the upper busbar of the aluminum electrolysis cell;

[0010] A square pressure plate is installed on the side wall of the upper shell of the aluminum electrolysis cell on one side of the upper busbar.

[0011] The adjustment mechanism is connected to the fixing mechanism at one end and to the square pressure plate at the other end, so as to adjust the gap between the upper busbar of the aluminum electrolysis cell and the upper shell of the aluminum electrolysis cell.

[0012] The fixing mechanism includes:

[0013] The slot plate is attached to the top of the upper busbar of the aluminum electrolysis cell.

[0014] The first fixing bolt, which is set horizontally, is threaded onto the outer sidewall of the slotted plate.

[0015] The adjustment mechanism includes:

[0016] The top plate, a channel steel structure, is installed on the inner side wall of the grooved plate;

[0017] The second fixing bolt, which is set horizontally, is inserted through the through hole on the side wall of the top plate. Its head is set inside the top plate and its tail is connected to the square pressure plate.

[0018] Adjust the nut and install it on the second fixing bolt.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model is easy to install. Only one person is needed to complete the adjustment of the horizontal position of the upper busbar of the aluminum electrolysis cell. After installation, it can be easily removed by loosening only one nut and one bolt. The number of workers is reduced from 3 to 1, which can effectively reduce labor costs.

[0021] 2. This utility model can be installed in advance during the overhaul process, avoiding operation in a strong magnetic environment, effectively reducing the impact of strong magnetism on the operation, and effectively reducing the risk of operation for employees.

[0022] 3. This utility model requires only 2 sets of single-slot jacks to complete the overall adjustment work. Compared with the current method of adjusting with 2 sets of ultra-thin hydraulic jacks and 4 sets of mechanical jacks at the same time, it can effectively reduce the use of a large number of tools and improve the service life of other tools.

[0023] 4. In this utility model, a 60mm×60mm×5mm square pressure plate is provided at the tail of the second fixing bolt. The purpose is to prevent the tail of the second fixing bolt from being embedded in the upper busbar of the aluminum alloy electrolytic cell, which is made of relatively soft material.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figure 1 As shown, a horizontal position adjustment device for the upper busbar of an aluminum electrolysis cell includes: a fixing mechanism, which is set on the top of the upper busbar 2 of the aluminum electrolysis cell; a square pressure plate 5, which is set on the side wall of the upper shell 3 of the aluminum electrolysis cell on one side of the upper busbar 2; and an adjustment mechanism, one end of which is connected to the fixing mechanism and the other end of which is connected to the square pressure plate 5, to realize the adjustment of the gap between the upper busbar 2 of the aluminum electrolysis cell and the upper shell 3 of the aluminum electrolysis cell.

[0029] like Figure 1 As shown, the fixing mechanism includes: a slotted plate 1, which is fastened to the top of the upper busbar 2 of the aluminum electrolysis cell; and a first fixing bolt 4, which is horizontally set and threaded onto the outer sidewall of the slotted plate 1.

[0030] like Figure 1 As shown, the adjustment mechanism includes: a top plate 6, a channel steel structure, set on the inner side wall of the slotted plate 1; a horizontally set second fixing bolt 8, inserted into the through hole on the side wall of the top plate 6, with its head set inside the top plate 6 and its tail connected to the square pressure plate 5; and an adjusting nut 7, which is fitted onto the second fixing bolt 8.

[0031] In use, before installation, the first fixing bolt 4 is removed to allow the slotted plate 1 to reach its maximum installation size for easy installation. Simultaneously, the adjusting nut 7 is adjusted to be close to the square pressure plate 5, i.e., the tail of the second fixing bolt 8, to allow the adjustment mechanism to reach its minimum installation size for easy installation. During installation, the slotted plate 1 is fastened to the top of the upper busbar 2 of the aluminum electrolysis cell, and the square pressure plate 5 is attached to the side wall of the upper housing 3 of the aluminum electrolysis cell. The first fixing bolt 4 is rotated so that its tail continuously moves towards the upper busbar of the aluminum electrolysis cell. 2. Move the adjusting nut 7 closer until it presses against the side wall of the upper busbar 2 of the aluminum electrolysis cell, thus locking the cell plate 1. Then, rotate the adjusting nut 7, making it move closer to the head of the second fixing bolt 8, until the adjusting nut 7 and the head of the second fixing bolt 8 clamp the side wall of the top plate 6. Install another set of this device at the tail of the aluminum electrolysis cell using the same method. Finally, measure and adjust to ensure that the extension length of the second fixing bolt 8 of the two devices is consistent. Measure the horizontal position of the upper busbar at both ends of the aluminum electrolysis cell without the adjusting device and compare it with the measurement taken during installation. Adjust the adjusting nut 7 again accordingly. Through repeated comparison and adjustment, ensure that the horizontal position deviation of the upper busbar 2 of the aluminum electrolysis cell is ≤5mm. After completion, remove the first fixing bolt 4, adjust the adjusting nut 7 to be close to the square pressure plate 5, and remove the device vertically upwards.

[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
