Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum electrolytic cell technology, specifically to an electrolytic cell shell-breaking device. Background Technology
[0002] In the production process of aluminum electrolysis cells, alumina is continuously added to the electrolyte solution at approximately 940°C within the electrolysis cell. However, a solid crust forms on the surface of the high-temperature electrolyte. When adding alumina, this crust must first be broken. The process of breaking the crust is called "shell breaking," and the equipment used to do so is called a shell breaking device. Currently, aluminum electrolysis cell shell breaking devices typically employ a cylinder-driven hammer rod structure. The cylinder, through air intake and exhaust, causes the cylinder rod to reciprocate, thereby driving the hammer rod back and forth (air pressure) to achieve the purpose of breaking the crust.
[0003] In actual production, compressed air is prone to pressure loss after passing through various pipelines, resulting in low cylinder pressure. This can lead to problems such as the inability to penetrate the crust or the hammer rod getting stuck. Typically, multiple cylinders and hammer rods are used to simultaneously strike different parts of the crust. While this method solves the problem of incomplete penetration, it increases the burden on the plant's air compressor station. Furthermore, the cylinders are located at the electrolytic cell inlet, where the high temperature environment affects their stable operation, leading to a high failure rate, frequent maintenance, reduced production efficiency, and inconvenience. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an electrolytic cell shell-breaking device. The drive unit can be installed at the end of the aluminum electrolytic cell, so that the drive unit is far away from the feed port, avoiding the hot air from breaking the drive unit. This is conducive to the stable operation of the entire device and reduces the failure rate. Moreover, one drive unit can drive the shell-breaking hammer rod of the entire electrolytic cell, which can greatly save production costs and reduce maintenance workload. It is easy to use and can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrolytic cell shell-breaking device, comprising a push rod and several shell-breaking hammer rods arranged along the length of the push rod. A drive unit is installed at one end of the push rod, and a groove is provided on the side of the push rod. A triangular plate is rotatably arranged inside the groove via a pin three. The triangular plate is rotatably arranged on the electrolytic cell via a pin two. A lifting lug is rotatably arranged at the lower end of the triangular plate via a pin one. The bottom of the lifting lug is connected to the shell-breaking hammer rods via an adjusting joint.
[0006] As a preferred embodiment of this utility model, both the upper and lower ends of the adjusting section are threaded groove structures, and the threaded groove at the upper end of the adjusting section is threadedly connected to the lower end of the lifting lug, and the threaded groove at the lower end of the adjusting section is threadedly connected to the upper side of the shell-beating hammer rod.
[0007] As a preferred embodiment of this utility model, an adjustment hole is provided in the middle of the side of the adjustment section.
[0008] As a preferred technical solution of this utility model, the end of the push rod near the drive unit is connected to the concave opening of the drive unit by a pin.
[0009] As a preferred technical solution of this utility model, the first pin and the third pin are set at the two acute angles of the triangle plate, and the second pin is rotatably set at the remaining corner of the triangle plate.
[0010] As a preferred embodiment of this utility model, the drive unit is either an electro-hydraulic actuator or a hydraulic cylinder.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The electrolytic cell shell-breaking device of this utility model can have its drive unit installed at the end of the aluminum electrolytic cell, keeping the drive unit away from the feed port. This avoids the hot air causing the drive unit to break, which is beneficial to the stable operation of the entire device and reduces the failure rate. Moreover, one drive unit can drive the shell-breaking hammer rod of the entire electrolytic cell, which can greatly save production costs, reduce maintenance workload, and is easy to use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 This utility model provides a technical solution: an electrolytic cell shell-breaking device, including a push rod 6 and several shell-breaking hammer rods 1 arranged along the length of the push rod 6. A drive unit 8 is installed at one end of the push rod 6. A groove is formed on the side of the push rod 6, and a triangular plate 10 is rotatably mounted inside the groove via a pin 3 5. The triangular plate 10 is rotatably mounted on the electrolytic cell via a pin 2 4, and a lifting lug 3 is rotatably mounted at the lower end of the triangular plate 10 via a pin 1 2. The bottom of the lifting lug 3 is connected to the shell-breaking hammer rods 1 via an adjusting joint 11. Figure 1 Taking the direction as an example: When the drive unit 8 is working, it makes a reciprocating linear motion. The drive unit drives the push rod 6 to reciprocate. When the push rod 6 moves to the left, it drives the triangle plate 10 to rotate around the pin 4. At this time, the triangle plate 10 drives the adjusting section 11 and the shell hammer rod 1 to move down through the lifting lug 3, thereby opening the shell of the aluminum electrolysis cell.
[0021] The drive unit 8 can be installed at the end of the aluminum electrolysis cell, keeping the drive unit 8 away from the feed port to avoid the hot air causing the drive unit 8 to break; and one drive unit 8 can drive the shell-breaking hammer rod 1 of the entire electrolysis cell to work, which can greatly save production costs, reduce maintenance workload, and is easy to use.
[0022] Furthermore, both the upper and lower ends of the adjusting section 11 are threaded groove structures, and the threaded groove at the upper end of the adjusting section 11 is threadedly connected to the lower end of the lifting lug 3, and the threaded groove at the lower end of the adjusting section 11 is threadedly connected to the upper side of the shell-beating hammer rod 1. An adjustment hole 12 is provided in the middle of the side of the adjusting section 11. By inserting the handle into the adjustment hole 12 and rotating the adjusting section 11 by the handle, the total effective length of the adjusting section 11 and the shell-beating hammer rod 1 can be adjusted.
[0023] Furthermore, the end of the push rod 6 near the drive unit is connected to the concave opening 7 of the drive unit 8 via a pin 4 9.
[0024] Furthermore, pin 1 2 and pin 3 5 are located at the two acute angles of triangle 10, while pin 2 4 is rotatably located at the remaining corner of triangle 10.
[0025] Furthermore, the drive unit 8 is either an electro-hydraulic actuator or a hydraulic cylinder.
[0026] When using:
[0027] by Figure 1 Taking the direction as an example: When the drive unit 8 is working, it makes a reciprocating linear motion. The drive unit drives the push rod 6 to reciprocate. When the push rod 6 moves to the left, it drives the triangle plate 10 to rotate around the pin 4. At this time, the triangle plate 10 drives the adjusting section 11 and the shell hammer rod 1 to move down through the lifting lug 3, thereby opening the shell of the aluminum electrolysis cell.
[0028] The drive unit 8 of this utility model can be installed at the end of the aluminum electrolysis cell, so that the drive unit 8 is far away from the feed port, avoiding the hot air from breaking the drive unit 8, which is conducive to the stable operation of the entire device and reduces the failure rate. Moreover, one drive unit 8 can drive the shell-breaking hammer rod 1 of the entire electrolysis cell to work, which can greatly save production costs, reduce maintenance workload, and is easy to use.
