Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic aluminum production equipment, specifically a buffer mechanism for shell breaking in an electrolytic aluminum unit. Background Technology

[0002] In the electrolytic aluminum production process, the shell-breaking device of the electrolytic aluminum unit is one of the key pieces of equipment. Its main function is to break up the electrolyte crust in the electrolytic cell to facilitate subsequent operations such as feeding and aluminum tapping. However, most traditional shell-breaking equipment does not have a dedicated buffer mechanism. The hammer head is in direct rigid contact with related components. The huge impact force and vibration generated during shell breaking directly affect the entire equipment, resulting in rapid wear of core components such as impact hammers and mounting bases. This not only shortens the service life of components but also increases the frequency of equipment failures, requiring frequent shutdowns for maintenance. This increases maintenance costs and seriously affects the continuity and efficiency of electrolytic aluminum production. Furthermore, due to the lack of a buffer force adjustment structure, the equipment is difficult to adapt to the shell-breaking requirements under different working conditions, resulting in poor operational stability.

[0003] Meanwhile, traditional equipment is not equipped with a dust removal mechanism. During the shell-breaking process, the impact of the hammer head generates a large amount of dust, which spreads into the production environment without any hindrance. On the one hand, this poses a serious threat to the health of operators, such as their respiratory system. On the other hand, the dust easily adheres to the surface of various parts of the equipment, aggravating component wear, increasing the risk of equipment failure, damaging the cleanliness and safety of the production environment, and restricting the stable operation of electrolytic aluminum production. Therefore, there is an urgent need to provide a buffer mechanism for shell-breaking in electrolytic aluminum units to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a buffer mechanism for shell breaking in an electrolytic aluminum unit, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a buffer mechanism for shell breaking in an electrolytic aluminum unit, comprising a mounting arm, a hammer mounting seat rotatably mounted on the front side of the mounting arm via a connecting rod assembly, an impact hammer placed inside the hammer mounting seat, and a hammer head provided at the lower end of the impact hammer; the buffer mechanism for shell breaking in an electrolytic aluminum unit includes a buffer mechanism and a dust removal mechanism, the buffer mechanism includes a hammer mounting seat, and an end cap is fixedly mounted on the top of the hammer mounting seat by four sets of fastening bolts.

[0006] Preferably, an adjusting screw is movably installed in the middle of the end cap, the lower end of the adjusting screw is fixedly installed on the pressure plate, and a buffer pad is fixedly installed below the pressure plate.

[0007] Preferably, a pre-tightening spring is fixedly connected between the pressure plate and the end cover, and a nut is movably installed on the upper end of the adjusting screw via a thread.

[0008] Preferably, the hammer mounting base has a second mounting rod and a third mounting rod movably mounted at its end. The second mounting rod passes through the hammer mounting base and its two ends are fixedly connected to the ends of the drive connecting rod.

[0009] Preferably, the other end of the drive linkage is rotatably mounted on the lower end of the mounting arm via a rotating rod. The inner side of the drive linkage is provided with a rotating rod for rotatably connecting with the connector at the end of the cylinder's output rod. The fixed end of the cylinder is rotatably mounted on the side of the mounting arm via a mounting rod. A protective shell is fixedly mounted on the outer side of the cylinder by bolts.

[0010] Preferably, an auxiliary connecting rod is rotatably mounted on the inner side of the mounting arm via a connecting rod, and the other end of the auxiliary connecting rod is rotatably mounted on the hammer head mounting seat via a mounting rod.

[0011] Preferably, the dust removal mechanism includes a hammer mounting base, a corrugated pipe is fixedly installed at the lower end of the hammer mounting base, a dust collection hood is fixedly installed at the lower end of the corrugated pipe, a limiting edge is provided on the inner side of the connection between the corrugated pipe and the dust collection hood, a groove is formed between the corrugated pipe and the limiting edge, a top pressure spring is provided in the groove, the other end of the top pressure spring is fixedly connected to the hammer mounting base, and an air extraction pipe is provided on the side of the dust collection hood, which is connected to an air pump through an air pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The buffer mechanism for shell-breaking in this electrolytic aluminum unit uses four sets of fastening bolts to fix the end cover to the top of the hammer head mounting base. This secure installation facilitates subsequent maintenance and disassembly. A pressure plate is connected to the lower end of an adjusting screw that is movably installed in the middle of the end cover. A buffer pad is located below the pressure plate, working in conjunction with a pre-tension spring between the pressure plate and the end cover. During the operation of the impact hammer, the buffer pad directly cushions the impact force of the hammer, while the pre-tension spring further absorbs vibration energy. This significantly reduces the impact and vibration experienced by the equipment during shell-breaking, reduces wear on components caused by severe collisions, extends the service life of core components such as the impact hammer and hammer head mounting base, and reduces the frequency of equipment failures and maintenance costs. Simultaneously, the nut at the upper end of the adjusting screw allows operators to flexibly adjust its position according to actual shell-breaking needs, thereby changing the compression degree of the pre-tension spring by the pressure plate and achieving precise adjustment of the buffering force. This allows the buffer mechanism to adapt to shell-breaking operations under different working conditions, improving the applicability and operational stability of the equipment and ensuring continuous and efficient electrolytic aluminum production.

[0014] 2. The buffer mechanism and dust removal mechanism of this electrolytic aluminum unit for shell breaking are equipped with a corrugated pipe and a dust collection hood at the lower end of the hammer mounting base. The air pump is connected to the side air extraction pipe of the dust collection hood. This allows for precise and concentrated adsorption and collection of dust generated around the hammer during the shell breaking process, preventing dust from spreading to the production environment and reducing the impact of dust on the health of operators. At the same time, it prevents dust from adhering to the surface of equipment parts, reducing the risk of wear or failure of parts caused by dust. This creates a clean and safe working environment for electrolytic aluminum production and ensures continuous and stable production. Attached Figure Description

[0020] 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.

[0021] Example 1:

[0022] Based on existing technology, most traditional shell-breaking equipment lacks a dedicated buffer mechanism. The hammer head and related components are in direct, rigid contact. The enormous impact force and vibration generated during shell breaking act directly on the entire equipment, leading to rapid wear of core components such as the impact hammer and mounting base. This not only shortens the service life of components but also increases the frequency of equipment failures, requiring frequent downtime for maintenance. This increases maintenance costs and severely impacts the continuity and efficiency of electrolytic aluminum production. Furthermore, due to the lack of a buffer force adjustment structure, the equipment struggles to adapt to different shell-breaking requirements under various working conditions, resulting in poor operational stability. Therefore, this device is equipped with a buffer mechanism. Please refer to [link / reference]. Figures 1-3 This utility model provides a technical solution: a buffer mechanism for shell breaking of an electrolytic aluminum unit, including a mounting arm 1, a hammer mounting seat 2 rotatably mounted on the front side of the mounting arm 1 via a connecting rod assembly, an impact hammer 3 placed inside the hammer mounting seat 2, and a hammer head 308 provided at the lower end of the impact hammer 3; the buffer mechanism for shell breaking of an electrolytic aluminum unit includes a buffer mechanism and a dust removal mechanism, the buffer mechanism includes the hammer mounting seat 2, and an end cover 301 is fixedly mounted on the top of the hammer mounting seat 2 by four sets of fastening bolts 302.

[0023] An adjusting screw 303 is movably installed in the middle of the end cover 301. The lower end of the adjusting screw 303 is fixedly installed on the pressure plate 306. A buffer pad 307 is fixedly installed below the pressure plate 306.

[0024] A preload spring 305 is fixedly connected between the pressure plate 306 and the end cover 301, and a nut 304 is installed on the upper end of the adjusting screw 303 via a thread.

[0025] The hammer mounting base 2 has a second mounting rod 206 and a third mounting rod 207 movably mounted at its end. The second mounting rod 206 passes through the hammer mounting base 2 and its two ends are fixedly connected to the ends of the drive connecting rod 205.

[0026] The other end of the drive linkage 205 is rotatably mounted on the lower end of the mounting arm 1 via the rotating rod 204. The inner side of the drive linkage 205 is provided with a rotating rod for rotatably connecting with the connector at the end of the output rod of the cylinder 203. The fixed end of the cylinder 203 is rotatably mounted on the side of the mounting arm 1 via the mounting rod 202. The outer side of the cylinder 203 is fixedly mounted with a protective shell 201 by bolts.

[0027] An auxiliary connecting rod 208 is rotatably mounted on the inner side of the mounting arm 1 via a connecting rod. The other end of the auxiliary connecting rod 208 is rotatably mounted on the hammer head mounting seat 2 via a mounting rod 207.

[0028] Cylinder 203 is the core driving component. Its fixed end is rotatably mounted on the side of mounting arm 1 via mounting rod 202. The outer protective shell 201 prevents the cylinder from being damaged by dust or impact. When the output rod of cylinder 203 extends or retracts, it rotates with the inner rotating rod of drive connecting rod 205 via its end connector, causing drive connecting rod 205 to reciprocate around rotating rod 204 (connected to the lower end of mounting arm 1) as a fulcrum. The other end of drive connecting rod 205 is connected to... The hammerhead mounting base 2 is fixedly connected. When the drive connecting rod 205 swings, it can drive the hammerhead mounting base 2 to rotate around the mounting rod 3 207 (connected to the auxiliary connecting rod 208), thereby adjusting the up and down angle of the hammerhead 308 and ensuring that the hammerhead can be accurately aligned with the electrolyte shell in the electrolytic cell. The auxiliary connecting rod 208 on the inner side of the mounting arm 1 is connected to the hammerhead mounting base 2 through the mounting rod 3 207. It can provide support when the hammerhead mounting base rotates, preventing it from shaking due to excessive force and ensuring the stability of the shell-breaking action.

[0029] The impact hammer 3 is placed inside the hammer head mounting base 2. When the shell is being broken, the reaction force generated by the hammer head 308 hitting the shell will cause the impact hammer 3 to bounce upward. At this time, the upper end of the impact hammer 3 first contacts the buffer pad 307 below the pressure plate 306. The buffer pad 307 absorbs part of the impact force through its own deformation. Then, the pressure plate 306 moves upward under the impact, compressing the preload spring 305 between it and the end cover 301. The preload spring 305 further absorbs the vibration energy through elastic deformation, avoiding direct rigid collision between the impact hammer 3 and the hammer head mounting base 2 and the end cover 301, and greatly reducing component wear. The end cover 301 is fixed to the hammer head mounting base 2 by four sets of fastening bolts 302. The top of seat 2 has a stable structure and is easy to disassemble. When it is necessary to adapt to different working conditions (such as different shell hardness), the nut 304 at the upper end of the adjusting screw 303 can be rotated: rotating the nut 304 clockwise will push the adjusting screw 303 to move downward, reducing the compression of the pressure plate 306 on the preload spring 305, thus reducing the initial elasticity of the preload spring 305 and reducing the buffering force; rotating the nut 304 counterclockwise will reduce the compression of the preload spring 305 and increase the buffering force, thus achieving precise adjustment of the buffering force.

[0030] Example 2:

[0031] Based on Embodiment 1, traditional equipment lacks a dust removal mechanism. During the shell-breaking process, the hammer impact generates a large amount of dust, which diffuses freely into the production environment. This poses a serious threat to the respiratory health of operators and other aspects of their health. Furthermore, the dust easily adheres to the surfaces of various equipment components, accelerating wear and tear, increasing the risk of equipment failure, compromising the cleanliness and safety of the production environment, and hindering the stable operation of electrolytic aluminum production. Therefore, this device is equipped with a dust removal mechanism. Please refer to [link / reference]. Figure 4This utility model provides a technical solution: a buffer mechanism for shell breaking in an electrolytic aluminum unit. The dust removal mechanism includes a hammer mounting base 2, a corrugated pipe 401 fixedly mounted at the lower end of the hammer mounting base 2, a dust collection hood 402 fixedly mounted at the lower end of the corrugated pipe 401, a limiting edge 404 provided on the inner side of the connection between the corrugated pipe 401 and the dust collection hood 402, a groove 405 formed between the corrugated pipe 401 and the limiting edge 404, a top pressure spring 406 provided in the groove, the other end of the top pressure spring 406 fixedly connected to the hammer mounting base 2, and an air extraction pipe 403 provided on the side of the dust collection hood 402, which is connected to an air pump through an air pipe.

[0032] The upper end of the corrugated pipe 401 of the dust removal mechanism is fixed to the lower end of the hammer mounting base 2, and the lower end is connected to the dust collection hood 402. The suction pipe 403 on the side of the dust collection hood 402 is connected to an external air pump through an air pipe. When the shell is being broken, the air pump starts to generate negative pressure. The dust generated by the impact of the hammer 308 will be covered by the dust collection hood 402 and then sucked into the dust collection device of the air pump through the suction pipe 403 to prevent the dust from spreading into the environment. The corrugated pipe 401 is extensible, and a limiting edge 404 is provided on the inner side of the connection between the corrugated pipe 401 and the dust collection hood 402, forming a groove between them. A top pressure spring 406 is installed inside 405. The other end of the top pressure spring 406 is fixed to the hammer head mounting seat 2. When the hammer head 308 moves up and down or adjusts its angle, the dust collection hood 402 will move synchronously with the hammer head: when the hammer head hits the shell downwards, the dust collection hood 402 first contacts the surface of the electrolytic cell, the top pressure spring 406 is compressed, and the bellows 401 contracts to prevent the dust collection hood from obstructing the movement of the hammer head; when the hammer head returns to its original position upwards, the top pressure spring 406 restores its deformation and pushes the dust collection hood 402 to return to its original position downwards, always maintaining a close distance with the surface of the electrolytic cell to ensure that the dust collection efficiency is not reduced.
