The disadvantage of this opening and closing method is: power failure or current reduction has a serious impact on the main process and technical indicators of the electrolytic cell series in normal production, especially in electrolytic aluminum plants that use self-provided power plants for direct power supply, power failure or current reduction will affect the operation of the power plant. Crew will have serious impact

Embodiment Construction
[0014] Embodiment of the present invention: four oil cylinders 1 are required for a short-circuit junction of a column bus bar, and the ends of the oil cylinders 1 are connected in pairs by flanges 7 to form a whole. The clamps 2 are connected as a whole, so that when the oil cylinder 1 is controlled by the hydraulic station 6 on the mobile trailer 5 through the hose 4, it can move rapidly at the same time, and the clamp 2 will also move rapidly accordingly, thereby realizing the column bus 9 and Quick opening or closing of short-circuit busbar 8.

The invention discloses an electrolytic cell hydraulic pressure short circuit ora opening / closing device, which comprises a riser bus (9). A clamping device (2) is clamped on a short circuit ora bus (8) through a tightening bolt (3), an oil cylinder (1) is connected with the clamping device (2), one end of a hose (4) is connected with a hydraulic station (6), and the other end is connected with an oil cylinder (1). The hydraulic station (6) is installed on a movable type holding car (5). The two oil cylinders are mutually connected through a flange (7). By utilizing the invention, the automatic opening / closing can be realized without power off or reduction of the electric current of the electrolytic cell production series, thus not only the electrolytic cell production series is ensured that the main process engineering criteria is not disturbed or affected by the power off or reduction of the electric current, but also the labor intensity of the worker is reduced simultaneously, and the labor capacity and the safety coefficient are enhanced. The invention can be used on the electrolytic cells with different volumes as the device for rapid opening / closing the short circuit ora of the riser bus.
Description
technical field [0001] The invention relates to a device for quickly opening and closing the short-circuit opening of the column bus bar of an electrolytic cell in aluminum electrolytic production. Background technique [0002] At present, when the electrolytic cell needs to be shut down for overhaul in aluminum electrolytic production, or put into use after the overhaul, or a new cell is put into use, it is necessary to open and close the short-circuit of the column busbar to carry out the above operations. In the prior art of aluminum electrolysis, the opening and closing of the short-circuit opening of the column busbar is usually performed manually in the case of power failure or current reduction. The disadvantage of this opening and closing method is: power failure or current reduction has a serious impact on the main process and technical indicators of the electrolytic cell series in normal production, especially in electrolytic aluminum plants that use self-provided ...
