[0002] In the field of aluminum electrolysis technology, the shell-breaking cylinder is used to break the shell layer on the electrolytic cell, allowing the electrolysis process to continue. Generally, after the shell-breaking cylinder breaks through the flame hole, the feeder is controlled to feed the material, which is then electrolyzed and melted in the electrolytic cell to produce molten aluminum.

[0003] In actual production, the hammerhead of the shell-breaking cylinder will experience a sticking phenomenon after a period of time. This sticking is a common problem in the electrolytic aluminum production process. Sticking refers to the phenomenon where electrolytes or other substances adhere to the hammerhead or cylinder during the shell-breaking process, forming clumps. This phenomenon may cause the shell-breaking cylinder to malfunction, affecting the normal feeding and shell-breaking operation of the electrolytic cell, and preventing the material from smoothly entering the electrolytic cell. Utility Model Content

[0004] This application provides a shell-breaking cylinder device that can solve the problem in the prior art where the shell-breaking cylinder hammer head easily sticks to the shell, resulting in low electrolysis efficiency and inability to proceed smoothly.

[0008] In some embodiments, the mounting part includes a plurality of mounting protrusions, the mating part includes mounting holes corresponding to the mounting protrusions, and the cleaning scraper is connected to the mounting protrusions.

[0009] In some embodiments, the scraping structure further includes a baffle plate located between the mounting protrusion and the cleaning scraper.

[0010] In some embodiments, the cleaning scraper is made of silicon carbide.

[0011] In some embodiments, the main body is cylindrical, and the end of the main body near the housing has a mounting structure for detachable installation with the housing.

[0012] In some embodiments, the mounting structure includes: a mounting groove, a corresponding mating groove provided on the housing, the mounting groove and the mating groove being inserted into each other, the mounting groove having a first mating hole and the mating groove having a second mating hole; and a mating bolt, which passes through the mounting groove and the mating groove to connect the mounting groove and the mating groove.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] In the field of aluminum electrolysis technology, the shell-breaking cylinder is used to break the shell layer on the electrolytic cell, allowing the electrolysis process to continue. Generally, after the shell-breaking cylinder breaks through the flame hole, the feeder is controlled to feed the material, which is then electrolyzed and melted in the electrolytic cell to produce molten aluminum.

[0028] In actual production, the hammerhead of the shell-breaking cylinder will experience a sticking phenomenon after a period of time. This sticking is a common problem in the electrolytic aluminum production process. Sticking refers to the phenomenon where electrolytes or other substances adhere to the hammerhead or cylinder during the shell-breaking process, forming clumps. This phenomenon may cause the shell-breaking cylinder to malfunction, affecting the normal feeding and shell-breaking operation of the electrolytic cell, and preventing the material from smoothly entering the electrolytic cell.

[0029] Please refer to Figures 1 to 3 To address the aforementioned technical problems, this application proposes a shell-breaking cylinder device 1000, comprising: a cylinder assembly 1, including a housing 11 and a push rod 12, the housing 11 extending in a first direction and having an opening 11a, the push rod 12 having a travel distance towards and away from the opening 11a in the first direction; a hammer assembly 2, connected to the push rod 12, the hammer assembly 2 being driven by the push rod 12 and having a travel distance along the first direction; and a cleaning assembly 3, including a main body 31 and a cleaning part 32, the main body 31 being detachably mounted on the housing 11, the cleaning part 32 protruding and annularly disposed on the inner surface of the main body 31 for contacting the hammer assembly 2, the cleaning part 32 and the main body 31 being detachably mounted.

[0030] Based on the shell-breaking cylinder device 1000 of this application embodiment, the cylinder assembly 1 has a housing 11 and a push rod 12. The housing 11 is used to accommodate the internal components and has an opening 11a. The push rod 12 is movably disposed inside the housing 11 and can reciprocate along a first direction. Since the push rod 12 is connected to the hammer assembly 2, it is convenient for the push rod 12 to drive the hammer assembly 2 to move in the first direction. The cleaning assembly 3 includes a main body 31 and a cleaning part 32. The main body 31 can be detachably assembled with the housing 11, thereby ensuring the replaceability of the main body 31 and facilitating the maintenance and replacement of the cleaning assembly 3. The cleaning part 32 protrudes and is arranged in a ring around the inner surface of the main body 31 to contact the hammer assembly 2. With this arrangement, during the movement of the hammer assembly 2, the cleaning part 32 can remove the residue on the hammer head and prevent it from adhering to the hammer head and affecting the next operation. Furthermore, the cleaning section 32 and the main body 31 are detachable, making the maintenance and replacement of the cleaning section 32 more convenient. This facilitates timely replacement of the cleaning section 32, preventing electrolyte residue from remaining on it and causing scratches to the hammer assembly 2. This protects the hammer assembly 2 while also maintaining the cleaning assembly 3. Therefore, the shell-breaking cylinder device 1000 of this application can effectively and in real time remove residues from the hammer head during operation, keeping the hammer head clean, thereby improving the shell-breaking effect and ensuring the cleaning and maintenance quality of the cleaning assembly 3.

[0031] It is understood that in some embodiments, the cleaning unit 32 includes a plurality of scraping structures 321, each scraping structure 321 being spaced apart along a first direction, and each scraping structure 321 being used to sequentially contact the hammer assembly 2. In the embodiments of this application, the effect of removing residues is further enhanced by providing a plurality of scraping structures 321. The scraping structures 321 being spaced apart along the first direction ensures that the hammer assembly 2 contacts a plurality of scraping structures 321 sequentially during movement, thereby ensuring that different positions and angles on the hammer head are effectively cleaned. This not only improves cleaning efficiency but also reduces wear on the hammer head caused by residues, extending the service life of the hammer assembly 2.

[0032] Furthermore, the arrangement of multiple scraping structures 321 increases the overall flexibility and adaptability of the cleaning unit 32. Maintenance can be performed by replacing a single scraping structure 321 without replacing the entire cleaning unit 32, thereby reducing overall maintenance costs.

[0033] Furthermore, the scraping structure 321 includes: an mounting part 3211 and a cleaning scraper 3212. The main body 31 is correspondingly provided with a mating part 311, and the mounting part 3211 is used to mate with the mating part 311 for installation. The cleaning scraper 3212 is located on the side of the mounting part 3211 near the inner surface of the main body 31, and the cleaning scraper 3212 is arranged in a ring shape. It can be understood that the mounting part 3211 and the mating part 311 are for detachable installation, thereby facilitating the scraping structure 321 to be easily disassembled and assembled with the main body 31. The cleaning scraper 3212 is the part of the scraping structure 321 that directly contacts the residue on the outer layer of the hammer assembly 2. It is installed on the side of the mounting part 3211 near the inner surface of the main body 31 and is arranged in a ring shape. The ring shape is used to ensure that the scraper can clean the residue on the hammer assembly 2 without dead angles. The material of the cleaning scraper 3212 should be selected to be wear-resistant and impact-resistant to ensure its service life and cleaning effect. This application does not limit the material. There are multiple ways to connect the mounting part 3211 and the mating part 311. In some embodiments, the mounting part 3211 includes a screw hole, and the mating part 311 includes a bolt and a mating screw hole on the main body 31. By using bolts to install the scraper structure 321 to the main body 31 and the mounting part 3211 respectively, the scraper structure 321 can be installed to the main body 31. In other embodiments, the mounting part 3211 and the mating part 311 also include corresponding magnetic structures, etc. This application does not limit them, as long as a detachable installation method can be achieved.

[0034] Please refer to Figure 2The mounting part 3211 includes multiple mounting protrusions 3211a, and the mating part 311 includes mounting holes 311a corresponding to the mounting protrusions 3211a. The cleaning scraper 3212 is connected to the mounting protrusions 3211a. The multiple mounting protrusions 3211a and the mounting holes 311a cooperate, allowing the mounting protrusions 3211a to be precisely inserted into the mounting holes 311a, thereby achieving a tight fit between the mounting part 3211 and the mating part 311. This connection method is simple, reliable, and convenient for installation and disassembly operations, providing a stable assembly effect and ensuring the stability of the contact between the cleaning scraper 3212 and the hammer assembly 2, thereby effectively scraping away residues on the hammer assembly 2. At the same time, the multiple mounting protrusions 3211a also increase the structural strength of the mounting part 3211.

[0035] In addition, the scraping structure 321 also includes a baffle plate 3213, which is located between the mounting protrusion 3211a and the cleaning scraper 3212. The baffle plate 3213 is used to cover the mounting hole 311a of the main body 31 to prevent residues from entering the mounting hole 311a when cleaning the hammer assembly 2, which would cause the mounting hole 311a and the mounting protrusion 3211a to stick together and make disassembly inconvenient. The baffle plate 3213 can block residues between the mounting protrusion 3211a and the cleaning scraper 3212. In some other embodiments, the baffle plate 3213 is made of an elastic and wear-resistant material, which can play a certain shock absorption and buffering effect before the mounting protrusion 3211a and the cleaning scraper 3212.

[0036] In some embodiments, the cleaning scraper 3212 is made of silicon carbide. It is understood that silicon carbide has high hardness and wear resistance, as well as high thermal stability and corrosion resistance. Since the cleaning scraper 3212 needs to contact the high-temperature hammer assembly 2 to remove residues, and these residues are corrosive, using silicon carbide as the cleaning scraper 3212 effectively enhances the durability of the cleaning assembly 3.

[0037] Please refer to Figures 2 to 3 The main body 31 is cylindrical, and one end of the main body 31 near the housing 11 has a mounting structure 312 for detachable installation with the housing 11. The hollow cylindrical shape of the main body 31 allows for the passage of the hammer assembly 2 and the installation and removal of the cleaning assembly 3. It is understood that the cleaning assembly 3 is detachably connected to the cylinder assembly 1 via the main body 31, and the mounting structure 312 cooperates with the housing 11 to facilitate the maintenance and replacement of the cleaning assembly 3.

[0038] Furthermore, the mounting structure 312 includes a mounting groove 3121 and a mating bolt 3122. The housing 11 is correspondingly provided with a mating groove. The mounting groove 3121 and the mating groove are interlocked. The mounting groove 3121 has a first mating hole, and the mating groove has a second mating hole. The mating bolt 3122 passes through the mounting groove 3121 and the mating groove to connect them. The mating groove of the housing 11 and the mounting groove 3121 of the main body 31 are connected and assembled. Through the interlocking of the mounting groove 3121 and the mating groove, the main body 31 and the housing 11 can be installed and mated. This design not only simplifies assembly but also enhances the stability of the connection. The mounting groove 3121 and the mating groove are respectively provided with a first mating groove and a second mating groove. Tightening the mating bolt 3122 facilitates a firm connection between the mounting groove 3121 and the mating groove, thereby ensuring a stable connection between the main body 31 and the housing 11. This design ensures the stability of the connection between the main body 31 and the housing 11 and the ease of assembly.

[0039] In addition, please refer to Figure 2 and Figure 3 The main body 31 includes a first half-cylinder 31a and a second half-cylinder 31b, which are detachably connected. The cleaning component 3 is also detachably connected to the first half-cylinder 31a and the second half-cylinder 31b. Understandably, on the one hand, the detachable connection between the first half-cylinder 31a and the second half-cylinder 31b allows the main body 31 to be assembled or disassembled as needed. This design enables the main body 31 to adapt to different usage scenarios or configuration requirements, improving the flexibility of disassembly and replacement. On the other hand, the detachable connection between the cleaning component 3 and the first half-cylinder 31a and the second half-cylinder 31b allows the cleaning component 3 to be easily replaced or cleaned, improving the maintainability and cleaning efficiency of the equipment. In some embodiments, a portion of the structure of the cleaning component 3 is a ring structure. The main body 31 is configured as a first half-cylinder 31a and a second half-cylinder 31b, which facilitates the disassembly of the ring-shaped cleaning component 3. By disassembling the first half-cylinder 31a and the second half-cylinder 31b, the engagement between the two can be released, and the ring structure that engages with it can naturally come off. Disassembly is convenient and facilitates cleaning or replacement of the cleaning component 3.

[0040] In the embodiments of this application, the first half-cylinder 31a and the second half-cylinder 31b are matched and installed through a groove to prevent residue from overflowing through the gap between them when removing residue. This connection ensures the safety of the shell-breaking cylinder device 1000.

[0041] Furthermore, the main body 31 also includes connecting bolts 313. The first half-cylinder 31a and the second half-cylinder 31b each have protruding connecting blocks at their mating joints, and the connecting bolts 313 pass through each connecting block. The connecting blocks provide fixation and support for the connecting bolts 313, and allow the connecting bolts 313 to be accurately aligned and inserted, thereby ensuring the robustness of the connection between the two half-cylinders. The connecting bolts 313 pass through each connecting block, and the connecting blocks are securely connected together by threads or other fastening methods. This insertion method is not only simple and easy to implement, but also provides a reliable connection effect.
