Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis technology, and in particular to an adjustable support for the upper shell-breaking cylinder of an electrolytic cell. Background Technology

[0002] The shell-breaking cylinder in an aluminum electrolysis cell is a key component used to break up the electrolyte crust during the aluminum electrolysis production process. During shell breaking, the cylinder drives the shell-breaking hammer to strike the electrolyte crust on the surface of the electrolysis cell with a certain impact force, breaking it and allowing raw materials such as alumina to be smoothly added to the cell, ensuring the smooth progress of the electrolysis process. However, existing shell-breaking cylinder supports are fixed structures, making it difficult to adapt to the adjustment requirements of the shell-breaking hammer depth under different operating conditions. On the one hand, with the continuous operation of electrolysis production, the fixed support cannot flexibly adjust the relative position of the shell-breaking cylinder hammer and the crust surface inside the cell, easily leading to shell breaking that is too shallow or too deep. On the other hand, the required shell-breaking depth varies depending on the batch of raw materials and different process parameters.

[0003] For example, Chinese patent publication number "CN201581142U" discloses a height-adjustable support for an aluminum electrolytic cell shell-breaking mechanism, consisting of a support body, pin holes, and an insulating sleeve. The two support bodies of the shell-breaking mechanism have two sets of pin holes that correspond vertically to each other. An insulating sleeve is installed inside the pin holes, and the intermediate shaft of the shell-breaking mechanism is fitted inside the insulating sleeve. This utility model addresses the current situation in the technology where the height of the shell-breaking mechanism is not adjustable, leading to the need to replace the entire set when the striking head becomes shorter and thinner due to burnt-out. It also addresses the issue of easily damaged insulation between the shell-breaking mechanism support and the electrolytic cell body, as well as the time-consuming and labor-intensive disassembly and assembly process during maintenance, resulting in low labor efficiency and a significant waste of human and material resources.

[0004] In actual use, there are still some problems and shortcomings: Since there are only two sets of pin holes, the shell-breaking mechanism can only be adjusted to two height positions. The fixed support has great limitations in adjusting the height of the shell-breaking mechanism, so it cannot meet the changing working conditions, which greatly affects the efficiency and stability of electrolytic production and increases production costs and equipment maintenance difficulty. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable support for the shell-breaking cylinder at the top of an electrolytic cell, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] An adjustable support for an upper shell-breaking cylinder of an electrolytic cell includes a base and an adjustment mechanism. The base is used to fix the shell-breaking cylinder support of the electrolytic cell. Vertical plates are fixedly connected to both sides of the upper surface of the base. A top seat is fixedly connected to the upper end of the two vertical plates. A lifting seat that can be raised and lowered is provided between the top seat and the base through the adjustment mechanism. A swing shaft seat for fixing the shell-breaking cylinder is fixedly installed on the surface of the lifting seat.

[0008] Preferably, the adjustment mechanism includes an adjustment screw and a locking nut. The upper and lower ends of the adjustment screw are rotatably connected to the top seat and the base, respectively. The middle part of the adjustment screw is threadedly connected to a fixing nut welded to the surface of the lifting seat. The locking nut is threadedly connected to the outside of the adjustment screw.

[0009] Preferably, the side of the lifting seat is provided with a limit locking component, which includes multiple locking bolts, which are threaded to both sides of the lifting seat respectively. The surface of the upright plate is provided with a lifting guide groove, through which the locking bolts pass.

[0010] Preferably, the length of the lifting guide groove is between 130 and 150 mm.

[0011] Preferably, the locking bolts are symmetrically distributed on both sides of the lifting seat.

[0012] Preferably, triangular reinforcing ribs are fixedly connected between the top base and the two upright plates, and the triangular reinforcing ribs are fixed by welding.

[0013] Preferably, the surface of the swing shaft seat has two threaded holes distributed on the left and right, and the surface of the lifting seat is threaded with two internal hexagon screws corresponding to the threaded holes.

[0014] This utility model has the following advantages and beneficial effects:

[0015] In this invention, the height of the lifting seat can be adjusted by setting an adjustment mechanism, thereby flexibly adjusting the striking depth of the shell-breaking cylinder hammer according to the actual working conditions of the electrolytic cell. This allows it to meet various working conditions and solves the problem of clogging and jamming of the shell-breaking cylinder hammer at the top of the electrolytic cell. It effectively reduces the labor intensity of electrolysis operators and greatly improves work efficiency. The height of the lifting seat can be adjusted simply by turning the adjusting screw with a wrench. The adjustment mechanism has an ingenious structural design and is easy to operate. Operators can master the adjustment method without professional skills training, making it easy to promote and apply in the workshop. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Example

[0024] like Figures 1-4 As shown, an adjustable support for an upper shell-breaking cylinder of an electrolytic cell includes a base 1, which is used to fix the shell-breaking cylinder support of the electrolytic cell. The upper surface of the base 1 is fixedly connected to both sides of the upright plate 2. The upper ends of the two upright plates 2 are fixedly connected to a top seat 3. A lifting seat 5 that can be raised and lowered is provided between the top seat 3 and the base 1 through an adjustment mechanism 4. A swing shaft seat 6 for fixing the shell-breaking cylinder is fixedly installed on the surface of the lifting seat 5.

[0025] like Figures 1-4As shown, the adjustment mechanism 4 includes an adjustment screw 7 and a locking nut 8. The upper and lower ends of the adjustment screw 7 are rotatably connected to the top seat 3 and the base 1, respectively. The adjustment screw 7 preferably has a 45# steel T-shaped thread that has been heat-treated to improve the screw strength. The middle part of the adjustment screw 7 is threadedly connected to a fixing nut 9 that is welded to the surface of the lifting seat 5. The locking nut 8 is threadedly connected to the upper end of the adjustment screw 7. When the locking nut 8 abuts against the top seat 3, the adjustment screw 7 cannot rotate. By setting the adjustment mechanism 4, the height of the lifting seat 5 can be adjusted, thereby flexibly adjusting the striking depth of the shell-breaking cylinder hammer according to the actual working conditions of the electrolytic cell, so that it can meet the changing working conditions. This solves the problem of caking and jamming of the shell-breaking cylinder hammer at the top of the electrolytic cell, effectively reduces the labor intensity of electrolysis operators, and greatly improves work efficiency.

[0026] By setting an adjusting screw 7 and a locking nut 8, and utilizing the principle of thread transmission, the height of the lifting seat 5 can be adjusted in the vertical direction simply by turning the adjusting screw 7 with a wrench. The adjusting screw 7 and the locking nut 9 are connected by a thread, making the adjusting mechanism 4 ingeniously designed and easy to operate.

[0027] like Figures 1-4 As shown, a limit locking assembly is provided on the side of the lifting seat 5. The limit locking assembly includes multiple locking bolts 10, which are threaded onto both sides of the lifting seat 5. A lifting guide groove 11 is provided on the surface of the upright plate 2. The locking bolts 10 pass through the lifting guide groove 11. By setting the limit locking assembly and the lifting guide groove 11, the lifting guide groove 11 limits the locking bolts 10, which can effectively prevent the lifting seat 5 from rotating. By rotating the locking bolts 10, the lifting seat 5 can be fixed by pressing the upright plate 2. With the locking nut 8, when the locking nut 8 and the top seat 3 abut, the adjusting screw 7 cannot rotate. The locking nut 8 must be separated from the top seat 3 before the adjusting screw 7 can be rotated, which can effectively improve the fixing effect of the lifting seat 5.

[0028] Since the common operating conditions of electrolytic cells are designed to fluctuate between 0-140 mm, and the length of the lifting guide groove 11 is between 130-150 mm, this design allows the difference between the adjustable maximum height and the adjustable minimum height of the lifting seat 5 to be between 0-150 mm, thus adapting to the common operating conditions of electrolytic cells.

[0029] like Figures 1-4 As shown, the number of locking bolts 10 can be four or six. Multiple locking bolts 10 are symmetrically distributed on both sides of the lifting seat 5. By setting multiple locking bolts 10, the fixing effect of the lifting seat 5 can be further improved. The material of the locking bolts 10 is high-strength steel with a carbon content of generally 0.3 to 0.5%. This design can improve the service life of the locking bolts 10.

[0030] like Figures 1-4 As shown, triangular reinforcing ribs 12 are fixedly connected between the top seat 3 and the two upright plates 2. The triangular reinforcing ribs 12 are fixed by welding. By setting the triangular reinforcing ribs 12, the connection strength between the top seat 3 and the two upright plates 2 can be improved to ensure that it can withstand the impact and vibration when the shell-punching cylinder is working.

[0031] like Figures 1-4 As shown, the surface of the swing shaft seat 6 has two threaded holes 13 distributed on the left and right. The surface of the lifting seat 5 is threaded with two internal hexagon screws 14 corresponding to the threaded holes 13. By screwing the internal hexagon screws 14 into the threaded holes 13, the swing shaft seat 6 can be installed and fixed. The swing shaft seat 6 is a pre-designed purchased finished part.

[0032] When installing the lifting seat 5 of the shell-breaking cylinder, first install the base 1 on the bolt hole of the original cylinder bracket in the electrolytic cell by bolt connection to ensure that the base 1 is horizontal and stable. Then, install the shell-breaking cylinder on the swing shaft seat 6 according to the standard installation procedure. The specific installation method is that the cylinder body of the shell-breaking cylinder has a rod on the circumference, and the rod is connected to the hole in the middle of the swing shaft seat 6.

[0033] When it is necessary to adjust the position of the shell-breaking cylinder, first turn off the air supply to the shell-breaking cylinder, loosen the multiple locking bolts 10 at both ends of the lifting seat 5 and the locking nut 8 on the outer surface of the adjusting screw 7, turn the adjusting screw 7 with a wrench, and the rotation of the adjusting screw 7 will cause the lifting seat 5 to rise or fall. Observe the scale on the lifting seat 5 or use an external measuring tool. After reaching the predetermined height, lock the multiple locking bolts 10 at both ends of the lifting seat 5 and the locking nut 8 on the outer surface of the adjusting screw 7.

[0034] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
