Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis technology, and in particular to a safety shell-breaking device for aluminum electrolysis cells. Background Technology

[0002] Aluminum electrolysis is one of the ways to produce aluminum. It uses an electrolytic process to produce aluminum, and commonly used equipment includes aluminum electrolysis cells. However, when using aluminum electrolysis cells, the electrolyte on the surface is prone to solidify into a shell, which affects the workers from feeding materials into the aluminum electrolysis cells. Therefore, in order to break the electrolyte shell in the aluminum electrolysis cells, it is usually necessary to use a shell-breaking device to hammer the electrolyte shell.

[0003] A search revealed a shell-breaking device for aluminum electrolytic cells (publication number CN217191980U), relating to the field of aluminum electrolysis technology. This device solves the technical problem of short cylinder lifespan in existing shell-breaking devices for aluminum electrolytic cells. The device includes a support frame, a drive structure, a transmission structure, and a hammer head structure. The drive structure is supported on the support frame, and the transmission structure connects the drive structure and the hammer head structure. The hammer head structure penetrates the electrolyte shell through extension / retraction of the transmission structure or by moving up and down through a portion connected to the hammer head structure. This invention minimizes the damage to the piston rod and cylinder seals, preventing internal and external leakage of compressed air, thus reducing the amount of compressed air used for shell breaking, significantly lowering the production costs of aluminum electrolysis plants, and reducing the workload of maintenance workers.

[0004] Based on the aforementioned patent, the dust in the workshop mentioned in the background technology has strong abrasive properties. As the piston rod moves, it will damage the seal between the piston rod and the cylinder, causing internal and external leakage of compressed air and shortening the service life. In response to this technical problem, this application proposes a safe shell-breaking device for aluminum electrolytic cells. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A safety shell-breaking device for aluminum electrolytic cells, comprising:

[0008] As a load-bearing structure, the mounting plate has lifting rods inserted through the middle of both the left and right ends.

This, in turn, moves the connecting rod and the hammer head to perform a shell-breaking operation on the aluminum electrolytic cell. This replaces the traditional cylinder drive, avoids the decrease in cylinder stability due to high temperature, and improves the safety of the device. A throttle handle drives a first screw to rotate, thereby adjusting the position of the first threaded block and the first shaft, and thus adjusting the range of motion of the lifting rod as needed.

[0020] In this invention, a second motor is activated, and through a pulley and belt, it drives the second screws on both sides to rotate synchronously, thereby driving the push plate to move and pushing the mounting plate to rise, thus adjusting the height. Attached Figure Description

[0029] Reference Figure 1 - Figure 3 One embodiment of this utility model provides: a safety shell-breaking device for aluminum electrolytic cells, comprising:

[0030] As a load-bearing structure, the mounting plate 1 has lifting rods 3 passing through the middle of both the left and right ends. Each lifting rod 3 has a connecting rod 4 at its lower end. The bottom end of the lifting rod 3 is movably connected to a pressure plate 19. The lower side of the pressure plate 19 is fixedly connected to the top of the connecting rod 4.

The lower end of the connecting plate 10 is rotatably connected to the outside of the second shaft 18.

[0033] The first motor 11 is started, which drives the rotating shaft 8 to rotate, which in turn drives the rotating rod 7 to rotate. The rotating rod 7 drives the connecting plate 10 to move through the first shaft 9, thereby pushing the second shaft 18 to move up and down, which in turn drives the lifting rod 3 to move up and down, which in turn drives the connecting rod 4 and the hammer head 6 to move up and down. The lifting block 17 is set to slide outside the limit rod 16, which can maintain the stability of the up and down movement of the second shaft 18. The handle 23 is set to drive the first screw 21 to rotate, which adjusts the movement of the first threaded block 22, thereby adjusting the position of the first shaft 9, thereby changing the distance of the up and down movement of the lifting rod 3, which is used to change the range of motion of the hammer head 6.

[0034] Reference Figure 1 , Figure 4 and Figure 5 As a fixed structure, the fixed plate 12 has telescopic rods 13 fixedly connected to the four corners of its upper side.

The upper end of the second threaded blocks 25 is rotatably connected to push plates 26. The upper end of the push plates 26 is rotatably connected to the lower side of the mounting plate 1. The left side of the left pad 14 is fixedly connected to a second motor 28. The drive end of the second motor 28 is fixedly connected to the left end of the front second screw 24.

[0035] The second motor 28 is connected to the second screw 24, which rotates and drives the second screw 24 on the other side to rotate through the pulley 27 and belt. This drives the second threaded block 25 and the push plate 26 to move, pushing the mounting plate 1 to move so that when the hammer head 6 moves to the lowest position, it just contacts the aluminum electrolysis cell.

[0036] Working principle: The first screw 21 is rotated by the throttle 23, which in turn drives the first threaded block 22 to move. The first shaft 9 is adjusted to the position of the rotating rod 7. The first motor 11 is started to drive the rotating shaft 8 to rotate, which in turn drives the rotating rod 7 to rotate. The rotating rod 7 drives the connecting plate 10 to move through the first shaft 9, which pushes the lifting rod 3 to move up and down inside the mounting plate 1, thereby driving the connecting rod 4 and the hammer head 6 to move and strike the aluminum electrolysis cell. The second screw 24 connected to the second motor 28 rotates, and drives the second screw 24 on the other side to rotate through the pulley 27 and belt, which in turn drives the second threaded block 25 and the push plate 26 to move, pushing the mounting plate 1 to move, so that when the hammer head 6 moves to the lowest position, it just contacts the aluminum electrolysis cell.
