Energy-saving crust cylinder for electrolytic aluminium industry

Abstract

The invention discloses an energy-saving crust cylinder for an electrolytic aluminium industry. The energy-saving crust cylinder comprises a large cylinder barrel (7) and is characterized in that the large cylinder barrel (7) is internally provided with a piston rod (11), a large piston (10) is arranged between the large cylinder barrel (7) and the piston rod (11), and a hook (9) and a spring piece (14) are arranged on the large piston (10); one end of the large cylinder barrel (7) is provided with a front cover (12), and the piston rod (11) passes through the front cover (12) and then is connected with a forked connecting rod (13); the large cylinder barrel (7) is internally connected with a small cylinder barrel (6) through a locating sleeve (15), and the small cylinder barrel (6) is internally provided with a small piston (4) and a guide piston (3); and the other end of the large cylinder barrel (7) is provided with a reversing valve assembly (2) which is connected with a sequence valve (1). The energy-saving crust cylinder for the electrolytic aluminium industry provided by the invention can obviously save the consumption of compressed air, reduce the energy consumption of an enterprise, and achieve energy conservation and emission reduction effects.

Description

Technical field: [0001] The invention relates to a cylinder, in particular to a shell-breaking cylinder with energy-saving effect applied in the electrolytic aluminum industry. Background technique: [0002] The main function of the shelling cylinder in the electrolytic aluminum industry is to break the surface crust every time the electrolytic cell is discharged, so as to ensure that the alumina raw material enters the electrolytic cell smoothly. The existing shelling cylinder is a double-acting single-piston-rod high-temperature-resistant cylinder, which can be divided into functionally: a material-feeding cylinder and an aluminum-discharging cylinder. During its operation, when the rodless chamber is pressurized, the rod chamber is in the exhaust state, and the piston rod extends; when the rod chamber is pressurized, the rodless chamber is in the exhaust state, and the piston rod is retracted. Can consume two chambers of compressed air in each action cycle of shelling cy...

AI Technical Summary

Problems solved by technology

In this way, two chambers of compressed air will be consumed in each action cycle of the shelling cylinder

In the normal production process of the existing shelling cylinder, the action frequency is high and the use is very frequent. The air consumption of the shelling cylinder in the daily production process accounts for about 20% of the compressed air consumption of the entire factory, which is the energy consumption of the electrolytic aluminum plant. one of the big
