Abstract
The invention discloses an intelligent crust breaking system and method for aluminium reduction cells. The system is composed of a crust breaking cylinder, a crust breaking rod, a crust breaking hammer, a pull rope displacement sensor, an electromagnetic valve and a control device. The crust breaking cylinder is connected with one end of the crust breaking rod, and the other end of the crust breaking rod is connected with the crust breaking hammer. A pull rope of the pull rope displacement sensor is fixed to the end, connected with the crust breaking hammer, of the crust breaking rod. The electromagnetic valve controls the crust breaking cylinder to act, and the crust breaking cylinder drives the pull rope displacement sensor to move through the crust breaking rod, so that the movement distance of the crust breaking cylinder is detected accurately. The method comprises the steps that the control device judges whether crust breaking is conducted in place or not through the movement distance of the crust breaking cylinder; if not, the control device controls the electromagnetic valve to conduct crust breaking repeatedly; and if a crust face is not broken after crust breaking is repeated for N times, the control device gives out an alarm and suspends alumina feeding to wait manual handling. According to the intelligent crust breaking system and method, the stroke of the cylinder can be controlled, the soak time of the hammer in an electrolyte can be shortened, the aperture ratio and good appearance of fire holes are guaranteed, and 'packet splicing' of the crust breaking hammer is prevented.
