Description

Technical Field

[0001] This utility model belongs to the field of electrolytic aluminum technology, specifically relating to a hydraulic shell-breaking mechanism for an electrolytic crane. Background Technology

[0002] Electrolytic aluminum is metallic aluminum extracted from alumina through electrolysis, also known as "primary aluminum". Its production is based on cryolite-alumina molten salt electrolysis technology, in which aluminum is deposited through an electrochemical reaction at high temperatures (950℃-970℃).

[0003] Shell removal is a key process in aluminum electrolysis production, referring to the physical removal of the hard shell layer formed on the surface of the electrolytic cell due to incomplete dissolution of alumina. This hard shell hinders electrolyte flow, affects the uniformity of material feeding and the efficiency of the electrolytic reaction, and can even lead to anodic effects or sediment buildup within the cell. If not addressed promptly, it can reduce the purity of the molten aluminum, increase energy consumption, and cause equipment wear. One aluminum electrolysis cell shell removal device, disclosed in CN220746107U, utilizes the torque of a metal plate to peel aluminum lumps separated by the slots from the outer wall of the shell removal component, completing the mechanical removal of the aluminum lumps and reducing labor costs and operational hazards. This technical solution upgrades the shell removal device to a certain extent, enabling automatic cleaning of aluminum lumps adhering to the outside of the shell removal equipment. However, it does not efficiently address the "sticking" phenomenon within the shell removal equipment. In the electrolytic aluminum production process, "sticking" refers to the phenomenon where a stubborn adhesion layer forms on the shell removal hammer or equipment surface due to the physicochemical reaction of high-temperature electrolyte and alumina, leading to a decline in equipment performance. Utility Model Content

[0004] To address the problem in existing technologies that cannot effectively remove the "sticking" of the shell-beating hammer, this invention provides a hydraulic shell-beating mechanism for an electrolytic crane.

The specific technical solution is as follows: An electrolytic crane hydraulic shell-beating mechanism includes: a mounting top plate; a cleaning and transporting structure is mounted on the lower wall of the mounting top plate; a cleaning and repositioning structure is mounted on the lower wall of the cleaning and transporting structure; two sets of cleaning structures are installed inside the cleaning and repositioning structure; and a shell-beating structure is mounted on the lower wall of the mounting top plate. The cleaning and transporting structure includes: a transport track, a transport support base, and a transport hydraulic cylinder.

The present invention provides a technical solution: a hydraulic shell-breaking mechanism for an electrolytic crane, comprising: a mounting top plate 1, a cleaning and transporting structure mounted on the lower wall of the mounting top plate 1, a cleaning and repositioning structure mounted on the lower wall of the cleaning and transporting structure, two sets of cleaning structures mounted inside the cleaning and repositioning structure, and a shell-breaking structure mounted on the lower wall of the mounting top plate 1; the cleaning and transporting structure includes: a transport track 2, a transport support 3, and a transport hydraulic cylinder 4; the transport track 2 is mounted on the lower wall of the mounting top plate 1, the transport support 3 is movably mounted on the lower wall of the transport track 2, and the transport hydraulic cylinder 4 is mounted on the lower wall of the mounting top plate 1 via a bracket, and the drive end of the transport hydraulic cylinder 4 is connected to the transport support 3.

[0017] As a preferred embodiment, the cleaning and shifting structure further includes: a rotating shaft 5, a driven gear 6, a shifting motor 7, a driving gear 8, and a shifting plate 9; the rotating shaft 5 is installed inside the carrier support 3 via bearings, the driven gear 6 is fixedly installed outside the rotating shaft 5, the shifting motor 7 is installed on the side wall of the carrier support 3, the driving gear 8 is installed on the drive end of the shifting motor 7, and the driving gear 8 and the driven gear 6 mesh together, the shifting plate 9 is installed on the lower wall of the rotating shaft 5, and the shifting motor 7 is a brake motor.

[0018] As a preferred embodiment, the two cleaning structures further include a cleaning motor 10 and a cleaning brush 11; the cleaning motor 10 is mounted on the lower wall via a motor bracket, and the cleaning brush 11 is mounted on the drive end of the cleaning motor 10, and the cleaning brush 11 can wrap around the shell-breaking hammer 13.

[0019] As a preferred embodiment, the shell-breaking structure further includes: a shell-breaking hydraulic device 12, a shell-breaking hammer 13, and a splash guard 14; the shell-breaking hydraulic device 12 is installed on the lower wall of the mounting top plate 1, the shell-breaking hammer 13 is installed on the drive end of the shell-breaking hydraulic device 12, and the splash guard 14 is installed on the outside of the shell-breaking hammer 13.

[0020] Working principle:

[0021] I. Preparation for Use: The operator installs the mounting plate 1 at the corresponding position on the electrolysis crane, and then connects the external AC power supply to this utility model to provide energy for the electrical appliances in this utility model. The operator connects the matching controller to this utility model to provide control for the electrical appliances in this utility model and to provide the working logic.

[0022] 2. Performing the shell-breaking operation: The shell-breaking hydraulic device 12 drives the shell-breaking hammer 13 to extend, and the shell-breaking hammer 13 breaks through the hard shell of the aluminum material. The anti-splash guard plate 14 can prevent the aluminum liquid from splashing.

[0023] III. Cleaning Operation: After the shell-beating hammer 13 has been used for a period of time, a slight sticking phenomenon may occur. At this time, the cleaning process can be initiated. The transport hydraulic cylinder 4 extends, driving the transport support 3 to move to the working position outside the transport track 2, and the transport hydraulic cylinder 4 remains extended in this position. The shifting motor 7 starts working, driving the drive gear 8 to rotate. Under the meshing of the gears, the driven gear 6 rotates, which drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the shifting plate 9 to rotate until the cleaning brush 11 covers the shell-beating hammer 13. At this time, the cleaning motor 10, which drives the cleaning brush 11, starts working. The rotation of the cleaning motor 10 drives the cleaning brush 11 to rotate, and the rotating cleaning brush 11 cleans the outside of the shell-beating hammer 13 to remove material until the shell-beating hammer 13 meets the usage standard. Then the shifting motor 7 and the transport hydraulic cylinder 4 reset, and the utility model returns to the initial position.
