Problems solved by technology

But in the actual process, because this control method cannot detect whether the working process of shelling cylinder extension is over, so for production needs, usually the time of the working process will be longer than the actual demand time, which will lead to the input time of high-pressure gas long
Due to the particularity of the electrolytic aluminum industry, high temperature

Embodiment Construction

[0017] When the solenoid valve (10) at the control end is opened, the control air source drives the two-position three-way single air control valve (12, 13) to reversing through the two-position five-way single-air control valve (11), so that the working air source will flow into The cylinder performs shelling work; at the same time, the control gas source gas flows into the mechanical position detection device (15) through the throttle valve (17) and the air inlet (9), and is discharged through the exhaust port (16). The control port of the valve (11) is connected to the downstream interface of the throttle valve (13). Due to the damping effect of the throttle valve (13), the gas pressure drops sharply, which is not enough to drive the two-position five-way valve for reversing, so that the opening The working process of the shell cylinder is successfully completed. When the piston moves to the bottom of the front end cover, the cylinder piston will push the spool (1) of the m...

Abstract

The invention relates to a novel intelligent crust breaking cylinder technology, belongs to the field of energy saving of pneumatic systems, and discloses a crust breaking cylinder mainly for the aluminum electrolysis industry. The intelligent crust breaking cylinder is quickly retracted after finishing crust breaking, so that the working time of the intelligent crust breaking cylinder under the action of the strongest heat source is greatly reduced, the crust breaking cylinder can run under the lowest pressure as much as possible, and the running time of high-pressure gas is reduced to greatly reduce the consumption of compressed air. The conventional crust breaking cylinder for the aluminum electrolysis industry is improved, so that the long-standing problem of incapability of detecting whether a cylinder head runs in place or not by adopting an electromagnetic signal in the severe working environment of the aluminum electrolysis crust breaking cylinder is radically solved. When a piston rod is in place, a mechanical cylinder position detection device can be triggered to generate a pneumatic pulse signal with certain pressure, and the retraction of the crust breaking cylinder can be controlled by combining the pneumatic pulse signal and a pneumatic loop.

Description

technical field [0001] The invention belongs to the field of energy saving of pneumatic systems, and relates to a shelling cylinder and a control air circuit in the electrolytic aluminum industry. Background technique [0002] The air consumption of cylinders in the electrolytic aluminum industry accounts for about 20% of the compressed air used in the entire factory, which is very important to the energy consumption of the entire factory. Effectively reducing the energy consumption of compressed air in cylinders and improving the use efficiency of compressed air in cylinders is the solution to electrolysis. An effective way to save energy in compressed air systems in the aluminum industry. [0003] The energy saving of shelling cylinder is the key technology in the field of energy saving of pneumatic system in electrolytic aluminum industry. The pneumatic system plays an important role in the shelling cylinder control process due to its advantages of low operating cost, no...
