Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal electrowinning, in particular to an electrowinning slot busbar electric transverse current device. Background Art

[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art for the technical solution of the present application.

[0003] The non-ferrous metal electrowinning production industry will involve short-circuit operations of direct current. The nickel electrowinning industry generally adopts insoluble anode diaphragm electrowinning technology. Nickel electrowinning devices mostly use parallel electrowinning cells, in which the electrowinning cells are energized in series. When it is necessary to perform production operations such as unloading the cell on a specific one or more electrowinning cells, it is necessary to power off the transverse electrical device connected to the copper busbar on the electrowinning cell without affecting the normal power supply of other electrowinning cells. Since the production operation uses a manual short-circuit device, the following problems arise in actual production: 1. The short-circuit switches distributed at both ends of the electrolytic cell (cell head and cell tail) cannot be opened and closed synchronously, resulting in frequent heating at the busbar closure; 2. Due to the different operating strengths of the operators, the short-circuit copper busbar of the transverse electric device has poor contact with the busbar at the cell head (cell tail), which will cause the short-circuit effect to deteriorate. In severe cases, the copper busbar may overheat and cause scalding accidents; 3. When the coating on the insoluble anode plate falls off and the conductive effect deteriorates, the cell voltage will rise sharply in a short period of time. In order to avoid DC short-circuit and current impact on silicon rectification, a transverse electric device must be used for emergency short-circuit operation. However, in this case, a strong arc will occur during short-circuit operation, which will cause safety risks. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, an automatic transverse electrification device for busbars of an electrolytic cell is provided. The electric transverse electrification device for busbars of an electrolytic cell is realized by the following technical solutions.

[0005] An electrolytic transverse electric device for an electrolytic cell busbar, characterized by comprising:

[0006] A fixing frame, an arc system and a driving system arranged on the fixing frame, a switch contact arranged in the fixing frame, a busbar connection copper bar fixing port arranged in the fixing frame, and a busbar connection copper bar fixed to the busbar connection copper bar fixing port,

[0007] The fixing frame includes a first support rod, a second support rod, an upper fixing plate, a lower fixing plate, one or more support plates, and fixing screws.

[0008] The arc system and the drive system are connected to the upper fixing plate by fixing screws, and the switch contact is fixed between the upper fixing plate and the lower fixing plate by fixing screws; the busbar connecting copper bar is fixed to the busbar connecting copper bar fixing port through the support plate.

[0009] In one embodiment, the arc system includes a capacitor, a bistable permanent magnet mechanism, and two relays.

[0010] In one embodiment, the driving system includes a three-phase AC asynchronous motor and two relays.

[0011] In one embodiment, the electrolytic cell busbar electric cross-current device includes four busbar connecting copper bars.

[0012] In one embodiment, the switch contacts include a main switch contact and an auxiliary switch contact.

[0013] In one embodiment, the busbar connecting copper bar is provided with installation fixing screw holes.

[0014] In one embodiment, the mounting screw hole includes a first side mounting screw hole and a second side mounting screw hole.

[0015] Beneficial technical effects of the utility model:

[0016] (1) The configuration of the arc system reduces the generation of strong arcs when the transverse electric device performs emergency short-circuit operations, thereby extending the life of the contacts and improving the safety of production operations.

[0017] (2) It uses a three-phase AC asynchronous motor drive, and the opening and closing of the switch are realized by two relays controlling the forward and reverse rotation of the motor; the operation of the control box is divided into two modes: "local" and "remote". When the "local" operation mode is selected, the short-circuit switch is operated by the panel; when the "remote" operation mode is selected, the short-circuit switch is operated by the host computer in the control room. This reduces the poor contact between the short-circuit copper bar of the cross-electric device and the busbar at the head (end) of the slot due to different operating forces of the operators, which will cause the short-circuit effect to deteriorate. In severe cases, the overheating temperature of the copper busbar causes scalding accidents.

[0018] (3) The four busbars at both ends are connected by copper bars, which play a shunting effect. On the one hand, it prolongs the service life of the contacts. On the other hand, it ensures that the two ends of the electrolytic cell (the head and the tail) are short-circuited at the same time, avoiding the occurrence of heating at the closed part of the busbar due to asynchronous opening and closing.
