Description

Technical Field

[0002] A large number of electrolytic cells are used in the electrolytic aluminum industry. During operation, the electrolytic cells need to be covered with thick electrolytes, fluoride salts and other powder materials on the anode and aluminum liquid to keep the electrolytic cells warm. However, these powder materials will continue to be tightly connected under the action of high temperature and electrolysis, and finally form a dense electrolyte shell surface. The electrolyte shell surface is often adhered to the anode carbon block, resulting in the inability to pull out the anode carbon block during the anode removal process, and even the anode carbon block and the anode aluminum guide rod falling off. In addition, the electrolyte shell surface will also hinder the feeding of alumina powder. Therefore, in the electrolytic aluminum workshop, the shell breaking device in the multi-functional overhead crane is usually used to vibrate and crush the electrolyte shell surface so that the residual anode can be removed smoothly.

[0003] During the operation of the shelling device, the hammer head at the end of the stroke will produce strong impact and collision when hammering the shell. The impact force of the hammer head causes the shelling lifting cylinder and even the entire shelling device to shake, which not only affects the accuracy and stability of the shelling, but may also cause damage to the shelling lifting cylinder and the shelling device, posing a threat to the stability and safety of electrolytic aluminum production.

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] In the electrolytic aluminum workshop, a hard electrolyte shell will form on the electrolytic cell during normal production. This shell must be pierced to ensure that alumina can enter the cell. The multifunctional overhead crane is a key mechanical equipment, and the shell breaking device is an important part of the multifunctional overhead crane. It can break the crust in the electrolytic cell through the hammer head to ensure the smooth progress of the electrolysis process. However, in the shell breaking device, the impact force of the hammer head causes the shell breaking lifting cylinder and even the entire shell breaking device to shake, seriously affecting the stability and safety of the operation.

[0031] In order to solve the above technical problems, the present application proposes an anti-sway device for a shell breaking lifting cylinder, which is applied to an electrolytic aluminum shell breaking device and aims to improve the stability and safety of the shell breaking lifting cylinder in the shell breaking device.

[0032] See also Figure 1-Figure 2 , Figure 1 This is a schematic structural diagram of an anti-sway device for a shell lifting cylinder according to an embodiment of the present application. Figure 2 The schematic diagram of the structure of an anti-sway device of a shell-breaking lifting cylinder in an embodiment of the present application is shown in the figure. In the embodiment of the present application, the shell-breaking device 5 includes a connecting frame 40 and a shell-breaking lifting cylinder 50, wherein the shell-breaking lifting cylinder 50 is arranged on the connecting frame 40. The anti-sway device 1 of the shell-breaking lifting cylinder 50 includes a mounting base 10, a buffer mechanism 20 and a mounting end cover 30, wherein the buffer mechanism 20 is connected to the shell-breaking lifting cylinder 50, which can effectively reduce the shaking of the shell-breaking lifting cylinder 50 when it is impacted, thereby protecting the equipment and improving work efficiency.

[0033] See also Figure 1-Figure 3 , Figure 3 This is a cross-sectional schematic diagram of an anti-sway device 1 of a shell lifting cylinder 50 according to an embodiment of the present application. The mounting base 10 can provide a stable support for the buffer mechanism 20.

[0034] In one embodiment of the present application, the mounting base 10 is disposed on the connecting frame 40 of the shell breaking device 5. Furthermore, the mounting base 10 is sleeved outside the shell breaking lifting cylinder 50 and is coaxially arranged with the shell breaking lifting cylinder 50. It can be understood that the inner diameter of the mounting base 10 is larger than the outer diameter of the shell breaking lifting cylinder 50, and an annular buffer space is formed between the two to set the buffer mechanism 20. Since the mounting base 10 is coaxial with the shell breaking lifting cylinder 50, the buffer mechanism 20 can be arranged at intervals in the annular buffer space, and more accurately sense and buffer the shaking of the shell breaking lifting cylinder 50 in all directions. In this way, the buffer mechanism 20 can more effectively absorb and disperse the impact force, reduce the shaking amplitude of the shell breaking lifting cylinder 50, and improve the operating stability of the equipment.

[0035] Specifically, see Figure 3-Figure 4 , Figure 4 This is a partially enlarged schematic diagram of an anti-sway device 1 of a shell lifting cylinder 50 according to an embodiment of the present application; the mounting base 10 includes a first mounting wall 11, a second mounting wall 12, a mounting bottom wall 13, a mounting guide column 14, and a mounting fixing portion 15. The first mounting wall 11 and the second mounting wall 12 are coaxially arranged annular walls, and the second mounting wall 12 is arranged on the relatively inner side of the first mounting wall 11, the mounting bottom wall 13 is arranged between the first mounting wall 11 and the second mounting wall 12, and the mounting fixing portion 15 is arranged on the side of the mounting bottom wall 13 away from the first mounting wall 11.

[0036] In one embodiment of the present application, the first mounting wall 11, the second mounting wall 12 and the mounting bottom wall 13 jointly define a mounting cavity 100. Further, the annular buffer space is formed between the inner wall of the second mounting wall 12 and the outer wall of the shell lifting cylinder 50. It can be understood that the mounting cavity 100 is used to install the buffer mechanism 20, and the buffer mechanism 20 is at least partially disposed in the mounting cavity 100 and at least partially disposed in the annular buffer space.

[0037] Furthermore, the installation guide column 14 is disposed in the installation cavity 100 , and the installation guide column 14 is disposed along the radial direction of the installation base 10 and connected to the inner wall surface of the first installation wall 11 . It can be understood that the installation guide column 14 is used to guide the buffer mechanism 20 .

[0038] In one embodiment of the present application, the mounting fixing portion 15 is connected to the connecting frame 40 so that the mounting base 10 and the anti-sway device 1 can be firmly connected to the connecting frame 40. In a specific implementation, the mounting fixing portion 15 and the connecting frame 40 can be connected by bolts, which can provide a stable connection and facilitate disassembly. It can be understood that the mounting fixing portion 15 can also be hinged with the connecting frame 40, and relevant technicians can flexibly set the connection method between the two according to the production environment of the workshop.

[0039] Continue to see Figure 1-Figure 4 The buffer mechanism 20 is connected to the mounting base 10 and to the shell breaking lifting cylinder 50, wherein the buffer mechanism 20 can buffer the shell breaking lifting cylinder that is shaken by impact.

[0040] In one embodiment of the present application, the buffer mechanism 20 includes a buffer plate 21 and an elastic buffer member 22. The buffer plate 21 is an arc-shaped plate and is fitted and connected to the circumference of the shell-breaking lifting cylinder 50, and one end of the elastic buffer member 22 is connected to the buffer plate 21, and the other end is connected to the mounting base 10. The buffer plate 21 is designed as an arc-shaped plate so that it can fit closely to the circumference of the shell-breaking lifting cylinder 50. This fitting connection method increases the contact area between the buffer plate 21 and the shell-breaking lifting cylinder 50, improves the buffering effect, and under the action of the elastic buffer member 22, the buffer plate 21 can move with the shell-breaking lifting cylinder 50 when it shakes, avoiding relative sliding or dislocation.

[0041] It is understandable that when the shell-breaking lifting cylinder 50 is impacted and shakes, the elastic buffer 22 can undergo elastic deformation, absorb the impact force and convert it into its own deformation energy, thereby reducing the shaking amplitude of the shell-breaking lifting cylinder 50. At the same time, the restoring force of the elastic buffer 22 can also support and position the shell-breaking lifting cylinder 50 to a certain extent, maintaining its stable working state.

[0042] In one embodiment of the present application, the elastic buffer 22 is a shock-absorbing spring. The shock-absorbing spring has excellent elasticity and restoring force, can effectively absorb and disperse the impact force, and provide a stable buffering effect for the shell lifting cylinder.

[0043] In one embodiment of the present application, the buffer mechanism 20 includes a plurality of buffer mechanisms 20 arranged at intervals, and the plurality of buffer mechanisms 20 are evenly spaced along the circumference of the shell-breaking lifting cylinder 50. First, the arrangement of the plurality of buffer mechanisms 20 can support and buffer the shell-breaking lifting cylinder 50 from multiple directions. Regardless of the direction of the impact force on the shell-breaking lifting cylinder 50, at least one or more buffer mechanisms 20 can respond quickly, absorb and disperse the impact force, thereby effectively reducing the amplitude of shaking. This all-round buffering effect can significantly improve the stability of the equipment. Secondly, the buffer mechanisms 20 are evenly spaced along the circumference of the shell-breaking lifting cylinder 50 to ensure that the force on the shell-breaking lifting cylinder 50 in all directions is uniform, which can avoid local stress concentration or deformation caused by uneven force and extend the service life of the shell-breaking lifting cylinder 50. In addition, the layout of the evenly spaced buffer mechanisms 20 also helps to improve the structural stability of the anti-sway device 1 of the shell-breaking lifting cylinder 50. The buffer mechanisms 20 interact with each other to form a stable support system, providing a more solid support for the shell-breaking lifting cylinder 50. ,

[0044] In one embodiment of the present application, the buffer plate 21 includes a support plate 211 and a buffer layer 212. Specifically, the support plate 211 is arranged on a side of the buffer plate 21 close to the elastic buffer 22, and the buffer layer 212 is arranged on a side of the buffer plate 21 away from the elastic buffer 22. The support plate 211 is pressed against the shell lifting cylinder 50 under the elastic force of the elastic buffer 22, and the buffer layer 212 is sandwiched between the support plate 211 and the shell lifting cylinder 50. It can be understood that the main function of the support plate 211 is to provide a solid support structure. Therefore, the material of the support plate 211 is usually selected to have a high strength and rigidity, such as metal, to ensure that it can withstand the pressure from the elastic buffer 22 and maintain a stable working state. The buffer layer 212 is to reduce the damage of the buffer plate 21 to the shell lifting cylinder 50, and to prevent the shell lifting cylinder 50 from interacting with the buffer plate 21, colliding or being compressed and deformed when the shell lifting cylinder 50 is shaken by force.

[0045] Furthermore, in the embodiment of the present application, the second mounting wall 12 is provided with mounting holes 120 at intervals in the circumferential direction, and the mounting holes 120 penetrate the second mounting wall 12. Among them, the elastic buffer 22 is sleeved outside the mounting guide column 14, one end of which is provided on the inner wall surface of the first mounting wall 11, and the other end is penetrated by the mounting hole 120 and connected to the buffer plate 21. The provision of the mounting guide column 14 not only provides the elastic buffer 22 with the function of installation and guidance, but also helps to maintain the stability of the elastic buffer 22 when it is under pressure. When the shell lifting cylinder shakes, the elastic buffer 22 can perform telescopic movement under the guidance of the mounting guide column 14, effectively absorbing and dispersing the impact force.

[0046] In a preferred embodiment of the present application, the mounting holes 120 include a plurality of mounting holes 120 disposed at intervals, the mounting guide posts 14 include a plurality of mounting holes 120 disposed at intervals, and the plurality of mounting holes 120 are disposed in one-to-one correspondence with the plurality of mounting guide posts 14. It can be understood that the plurality of mounting holes 120 and the plurality of mounting guide posts 14 provide the possibility of mounting a plurality of buffer mechanisms 20.

[0047] It is understandable that in the embodiment of the present application, the number of the buffer mechanism 20 , the number of the mounting holes 120 , and the number of the mounting guide columns 14 are the same, and relevant technicians can set the number of the three according to the outer diameter of the shell lifting cylinder 50 .

[0048] In the embodiment of the present application, the mounting end cover 30 is connected to the mounting base 10. It can be understood that in the embodiment of the present application, the mounting cavity 100 of the mounting base 10 is open at one end away from the mounting bottom wall 13, so the mounting end cover 30 is used to close the mounting cavity 100 in the axial direction of the mounting base 10 to prevent foreign matter, dust, etc. from entering the mounting cavity 100.

[0049] In one embodiment of the present application, an end of the first mounting wall 11 away from the mounting bottom wall 13 is provided with an internal thread, and the mounting end cover 30 includes a connecting portion 31, and the outer wall of the connecting portion 31 is provided with an external thread, wherein the connecting portion 31 is threadedly connected to the first mounting wall 11. Threaded connection, as a common mechanical connection method, has the advantages of simple structure, reliable connection, and convenient disassembly. In the present application, the mounting end cover 30 is fixed to the first mounting wall 11 by threaded connection, which not only ensures the stability of the connection, but also facilitates subsequent maintenance and replacement operations.

[0050] It can be understood that, in the embodiment of the present application, the mounting end cover 30 and the mounting base 10 can also be connected by screws / bolts to achieve a stable connection between the two.
