Abstract

The invention discloses an electrolytic aluminium crust breaking cylinder sealing system, which comprises a Tekang double-acting dust seal (1), a tetrafluoro bronze dust seal (2), a bearing pedestal (3), a self-lubricating bearing (4), a gland (5), an aerodynamic axial lip-shaped loop (6), an O-shaped loop (7), a high-strength tetrafluoro graphite seal (8), an oil-storage chamber (9), a lip-shape loop for an aerodynamic hole (10) and a guidance tape (11), wherein the Tekang double-acting dust seal (1), the tetrafluoro bronze dust seal (2), the bearing pedestal (3), the self-lubricating bearing (4) and the aerodynamic axial lip-shaped loop (6) are installed inside the groove of the gland (5); the high-strength tetrafluoro graphite seal (8) is installed on a front cover and is fixed through the gland (5); and the lip-shaped loop for the aerodynamic hole (10) and the guidance tape (11) are installed on an air cylinder piston. The electrolytic aluminium crust breaking cylinder sealing system provided by the invention is adopted to raise the service life of the cylinder, minimize maintenance workload, decrease the discharge capacity of compressed air and reduce energy waste by more than 20%.

Description

Technical field [0001] The invention relates to an electrolytic aluminum shelling cylinder sealing system. Background technique [0002] The existing electrolytic aluminum shelling cylinder is a special cylinder used in electrolytic aluminum plants. Its functions are divided into two types: blanking shelling and aluminum tapping. When in use, compressed air enters the cylinder through the pipeline to drive the hammer to drop quickly. After the shelling is completed, the cylinder is quickly retracted by controlling the direction of the reversing valve. The commonly used material for the existing cylinder seal is a fluorine rubber lip ring. During use, the ambient temperature of the cylinder is 150 °C Above temperature, the dust is serious, and the cylinder moves fast and suffers severe lateral impact during shelling. Affected by factors such as high temperature, high speed, eccentric load, poor lubrication conditions, etc., the sealing ring fails in a short time, which affects t...
