Abstract

This utility model discloses a shell-breaking and feeding system for an aluminum electrolysis cell, specifically relating to the field of aluminum electrolysis technology. It includes a controller and multiple shell-breaking motors, multiple shell-breaking transmission devices, multiple feeding motors, and multiple feeding transmission devices mounted on a steel plate above the electrolysis cell. The output shaft of one shell-breaking motor is connected to the input end of one shell-breaking transmission device, and the output end of the shell-breaking transmission device is fixedly connected to a shell-breaking hammer. The shell-breaking motor enables the shell-breaking transmission device to operate and drives the shell-breaking hammer to move up and down. The output shaft of one feeding motor is connected to the input end of one feeding transmission device, and the output end of the feeding transmission device is fixedly connected to a feeding bell. The feeding motor enables the feeding transmission device to operate and drives the feeding bell to move up and down. Each shell-breaking motor and each feeding motor is connected to the controller via a signal connection. This utility model can reduce equipment failures, lower maintenance risks, and ensure efficient and stable electrolysis production.
