Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis cell technology, and in particular to an anti-sticking hammer head for intelligent shelling of aluminum electrolysis cells. Background Technology

[0002] An aluminum electrolytic cell is the core device in the aluminum electrolysis industry used to produce metallic aluminum. It produces molten aluminum by electrolyzing molten alumina. During the electrolysis process, in order to maintain the continuity and stability of the electrolysis reaction, it is necessary to periodically perform a "shell-breaking and material feeding" operation on the electrolyte crust in the electrolytic cell. This operation relies on the impact and breakup of the crust by a shell-breaking hammer to provide a channel for the addition of alumina raw materials.

[0003] The prior art publication number "CN119824486A" discloses an "Automatic Cleaning Device for Hammer Head Adhesion during the Shelling Process of Aluminum Electrolytic Cells". Through the coordinated work of multiple mechanisms, the cleaning hammer strikes and the blade cuts during the lifting and lowering of the hammer head, effectively peeling off the shell head, reducing manual intervention, and improving shelling accuracy and efficiency. It is suitable for automated cleaning operations in special environments such as high temperature and corrosion. However, the system still has the following problems.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing hammerheads mainly use scrapers to prevent sticking, but the scrapers are fixed in a fixed position, which limits the scraping area and makes it difficult to scrape multiple areas of the round hammerhead, resulting in scraping dead corners. In addition, the cleaning effect of simply relying on scraping is limited, and the material is still easily adsorbed on the surface of the hammerhead. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing hammer scraper has limited effect and is still prone to adsorbing electrolytes. To address this, we propose an intelligent anti-sticking hammer for aluminum electrolysis cells.

[0006] To achieve the above objectives, this application adopts the following technical solution: an intelligent anti-sticking hammerhead for aluminum electrolysis cell shelling, comprising a cylinder, a hydraulic rod connected to the lower part of the cylinder, a hammerhead body connected to the lower part of the hydraulic rod, a sliding block provided on the outer side of the hammerhead body, a scraper connected to the lower part of the sliding block, a second gear connected to the upper part of the sliding block, a driven rod connected to the center of the second gear, a connecting belt sleeved on the outer side of the driven rod, a driving rod sleeved on the other side of the connecting belt, a first gear connected to the center of the driving rod, a toothed block connected to the side of the first gear, and a vibration mechanism also provided inside the hammerhead body.

[0007] Preferably, the vibration mechanism includes a mounting plate located inside the hammer body. The mounting plate forms a rubber damping structure with the hammer body through a rubber layer. The mounting plate is connected to the housing of the vibration motor by threaded screws. The rubber layer prevents the vibration motor from being damaged by vibration.

[0008] Preferably, a vibration rod is connected to the bottom of the vibration motor. The vibration rod is fixedly connected to the auxiliary block. Three guide rods are evenly distributed below the auxiliary block. The guide rods are attached to the top of the hammer body. Through the cooperation between the guide rods and the hammer body, the vibration of the vibration rod is transmitted to the hammer body, ensuring the removal of debris.

[0009] Preferably, the top of the hammer head body is provided with a top cover, the hammer head body is composed of a hollow cavity and a solid layer, and the connection between the hammer head body and the hydraulic rod is a fixed connection. The top cover facilitates the opening of the hammer head body for inspection and maintenance of the vibration mechanism.

[0010] Preferably, the hydraulic rod has teeth evenly and equidistantly distributed on its side. The teeth are connected to the first gear in a meshing manner. The first gear forms a rotating structure with the channel through the drive rod. The hydraulic rod drives the teeth to rise and fall, thereby meshing with the first gear and causing the drive rod to rotate.

[0011] Preferably, the sliding block is connected to the channel by a sliding connection. Scrapers are evenly and equidistantly distributed below the sliding block. The sliding block is meshed with the second gear through the gear block above it. The sliding block can rotate by cooperating with the second gear.

[0012] Preferably, the second gear and the driven rod are coaxially rotating. The second gear and the first gear are connected by a connecting belt to form a rotating connection structure. The driven rod is connected to the channel by a rotating connection. The second gear and the driven rod cooperate to make the second gear rotate with the first gear.

[0013] The technical effects and advantages of this utility model are as follows: In this invention, a movable scraper is provided to ensure a clean range without dead angles: a sliding block is provided inside the hammer body and the channel for sliding connection. When the hammer body is raised and lowered, it drives the first gear to rotate. The first gear drives the sliding block to rotate through the second gear, so that the scraper rotates automatically when the hammer body is raised and lowered, ensuring a clean range without dead angles and preventing sticking.

[0014] In this invention, a vibration mechanism is used to vibrate the hammer head body at high frequency to reduce the amount of debris: by setting a vibration motor and a guide rod in the hollow cavity inside the hammer head body, the hammer head body vibrates at high frequency during the rising process, thereby causing the electrolyte to fall off due to high-speed vibration before it has formed, thus reducing the amount of debris remaining on the surface of the hammer head body.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a technical solution: an intelligent anti-sticking hammer head for aluminum electrolysis tank shelling, including a cylinder 1, a hydraulic rod 7 connected to the lower part of the cylinder 1, which drives the hammer head body 4 to rise and fall, realizing automatic hammering. The hammer head body 4 is connected to the lower part of the hydraulic rod 7, and the hammer head body 4 hammers the raw materials inside the electrolyte tank for processing. A sliding block 5 is provided on the outer side of the hammer head body 4, which drives the scraper 6 to rotate, performing scraping without dead angles. The scraper 6 is connected to the lower part of the sliding block 5, which scrapes away impurities to prevent electrolyte from accumulating on the surface of the hammer head body 4. A second gear 13 is connected to the upper part of the sliding block 5, and the second gear 13 meshes with the sliding block 5 to facilitate its rotation. The second gear 13 is connected to a driven rod 12 at its center. The driven rod 12 limits the rotation of the second gear 13. A connecting belt 11 is sleeved on the outside of the driven rod 12 for connection. A driving rod 10 is sleeved on the other side of the connecting belt 11. The driving rod 10 is fixed to the first gear 9 to prevent it from sliding. The center of the driving rod 10 is connected to the first gear 9. The first gear 9 meshes with the tooth block 8 to realize the integrated operation of the equipment. The side of the first gear 9 is connected to the tooth block 8. The tooth block 8 is fixedly connected to the hydraulic rod 7 to drive the first gear 9 to rotate. The hammer body 4 is also equipped with a vibration mechanism 2. The vibration mechanism 2 vibrates the electrolyte and shakes it off before it cools down, reducing adhesion.

[0019] Reference Figure 1 , Figure 3 and Figure 4 As shown in this embodiment: the vibration mechanism 2 includes a mounting plate 201 located inside the hammer body 4. The mounting plate 201 forms a rubber damping structure with the hammer body 4 through a rubber layer 202. The mounting plate 201 is connected to the housing of the vibration motor 203 by a threaded connection. The rubber layer 202 prevents the vibration motor 203 from being damaged by vibration. A vibration rod 204 is keyed to the bottom of the vibration motor 203. The vibration rod 204 is fixedly connected to the auxiliary block 205. Three guide rods 206 are evenly distributed below the auxiliary block 205. The guide rods 206 are attached to the top of the hammer body 4. Through the cooperation between the guide rods 206 and the hammer body 4, the vibration of the vibration rod 204 is transmitted to the hammer body 4, ensuring the removal of debris.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in this embodiment: the top of the hammer body 4 is provided with a top cover. The hammer body 4 is composed of a hollow cavity and a solid layer. The hammer body 4 and the hydraulic rod 7 are connected by a fixed connection. The top cover is used to facilitate opening the hammer body 4 for inspection and maintenance of the vibration mechanism 2.

[0021] Reference Figure 1 and Figure 2 As shown in this embodiment: The hydraulic rod 7 has evenly spaced toothed blocks 8 on its side. The toothed blocks 8 are meshed with the first gear 9. The first gear 9 forms a rotating structure with the channel 3 via the drive rod 10. The hydraulic rod 7 drives the toothed blocks 8 to rise and fall, thus meshing with the first gear 9 and causing the drive rod 10 to rotate. The sliding block 5 is slidably connected to the channel 3. Scrapers 6 are evenly spaced below the sliding block 5. The sliding block 5 is meshed with the second gear 13 via the gear block above it. The sliding block 5 can rotate by engaging with the second gear. The second gear 13 and the driven rod 12 are coaxially rotating. The second gear 13 forms a rotating connection with the first gear 9 via the connecting belt 11. The driven rod 12 is rotatably connected to the channel 3. The second gear 13 rotates with the first gear 9 by engaging with the driven rod 12.

[0022] Working principle: First, during use, cylinder 1 drives hammer body 4 to rise and fall through hydraulic rod 7, causing hammer body 4 to descend inside channel 3 and enter the aluminum electrolysis cell to hammer the raw materials. When hammer body 4 rises, some electrolyte remains on the surface of hammer body 4. However, the temperature inside the aluminum electrolysis cell is extremely high, and the electrolyte adhering to the surface of hammer body 4 has not completely cooled down. Vibration motor 203 drives auxiliary block 205 to vibrate through vibration rod 204, and the guide rod 206 below auxiliary block 205 transmits the vibration to hammer body 4, thereby shaking off some electrolyte. Simultaneously, as the hammerhead body 4 continues to rise with the hydraulic rod 7, the hydraulic rod 7 drives the toothed block 8 to rise. The toothed block 8 meshes with the first gear 9, causing the first gear 9 to rotate with the driving rod 10. Then, the driving rod 10 drives the driven rod 12 to rotate through the connecting belt 11, thereby causing the second gear 13, which rotates coaxially with the driven rod 12, to rotate. The second gear 13 meshes with the sliding block 5, causing the sliding block 5 to start rotating with the channel 3. At this time, the scraper 6 also rotates, that is, the scraper 6 scrapes off the cooled electrolyte. Since the scraper 6 is rotating, there is no dead angle.

[0023] It should be noted that the vibration motor 204 can be a PZT-8 type piezoelectric ceramic stacked vibrator.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
