Embodiment 1

[0020] Such as figure 2 shown, for figure 1 A structure of the short-circuit opening and closing device, the process of using the short-circuit opening and closing device to connect and disconnect the short-circuit opening is as follows:

[0021] The insulating action part 2 is an array of insulating wedges, which can move in a straight line along a fixed direction inside the short-circuit opening and closing device through external driving action. There is a certain gap inside the short-circuit opening and closing device, and the internal conductive contacts 6 and The insulating action parts 2 are interlaced with each other. When the insulating wedge moves to the inner gap, it has no supporting effect on the conductor. The bus short-circuit port 7 described above is connected. At this time, the working current flows from the anode bus bar through the short-circuit port switching device, and directly enters the cathode bus bar to short-circuit the current electrolyzer.

Embodiment 2

[0025] Such as image 3 shown, for figure 1 Another structure of the switching device for the short-circuit opening, the insulating action part 2 is an expansion body structure, and the process of connecting and disconnecting the short-circuit opening by using the opening and closing device is as follows:

[0026] The insulating action part 2 is an array of insulating expansion bodies. The volume of the expansion body is controlled by the fluid pipeline. The internal conductive contacts 6 and the expansion bodies are interlaced. When the volume of the expansion body increases, it supports the conductor 1 Function to overcome the pressure of the external auxiliary spring 4, the internal conductive contact 6 is not in contact, then the bus short circuit 7 is disconnected, at this time the working current flows from the anode bus through the electrolyzer, and then enters the cathode bus, the current electrolyzer is normally energized.

[0027] When the volume of the expansion bo...

Abstract

The invention discloses a switch device for an electrolytic cell insulation intersection. The switch device is characterized in that the switch device consists of conductors, inner conductive contacts, an auxiliary spring, insulated action parts and elastic insulators, wherein the number of the conductors is two, the conductors are arranged on the two contact surfaces of the switch device and theinsulation intersection, the outside of each conductor has a plane structure and closely sticks to the electrolytic cell bus insulation intersection under the action of the auxiliary spring, the inside of each conductor has a symmetric curved surface structure with raised contacts to construct the inner conductive contacts; the auxiliary spring is arranged outside the switch device and used to press the insulation intersection and the switch device; and the insulated action parts and elastic insulators are uniformly distributed in the switch device, the shape of the insulated action parts is matched with the inner shape of each conductor, each insulated action part moves or changes shape to connect or disconnect the conductive contacts, and the elastic insulators are used to support the two conductors. By adopting the switch device disclosed by the invention, the bus insulation intersection can be opened or closed under the condition of not opening the insulation intersection; and theswitch device has simple structure and is convenient to operate.

Description

technical field [0001] The invention relates to an aluminum electrolytic smelting technology, in particular to a short-circuit port separation and closing device for an aluminum electrolytic cell. Background technique [0002] Aluminum is produced by cryolite-alumina molten salt electrolysis, and the electrolytic cell is an important equipment for the aluminum electrolysis industry. According to the principle of electrolytic production, the power supply bus flows in from the anode of each electrolytic cell and flows out of the cathode. Multiple electrolytic cells are connected in series according to a certain working current to form a production series. There is a connecting port between the anode bus bar and the cathode bus bar of each electrolytic cell, which is used to short-circuit the electrolytic cell, which is called a short circuit port. The bus bar is made of aluminum strips, so the opening of the short circuit has a certain range. When the electrolytic cell is w...
