Description

TECHNICAL FIELD

[0002] At present, in the aluminum smelting industry, the electrolytic cell anode lifting mainly relies on the lifting control system of the cell control machine, and the horizontal busbar lifting is realized by controlling the anode lifting motor, so that the adjustment of the electrolytic cell pole distance is completed, and the required energy balance of the electrolytic cell is reached.

[0003] For example, the 600KA electrolytic cell anode busbar AB surface is composed of two busbars, which are lifted by four hoists on each surface. In the production process, the anode angle part is prone to abnormal growth or protrusion, or a single hoist is damaged, which easily causes busbar dislocation and four busbars cannot be lifted at the same time, which affects the normal production.

One of the busbar front end and the busbar rear end is fixed with a travel switch at the edge position, and the other is fixed with a trigger baffle at the edge position. The contact of the travel switch extends into the trigger baffle. The travel switch is connected to the control mechanism, and the control mechanism is connected to an alarm mechanism. The above-mentioned patent uses the existing power jump detection port and acquisition board power jump detection line of the cell control machine to connect the travel switch to detect whether the busbar is dislocated. When the busbar is dislocated and touches the detection switch, the signal is interrupted, it is judged that there is a fault, and an alarm signal is sent to the scene to alarm the fault. However, in the above-mentioned patent, when the travel switch touches the trigger baffle (upper or lower trigger plate), if the horizontal busbar lifting cannot be stopped in time, the dislocation will continue to occur, which will cause the travel switch and the upper or lower trigger plate to be damaged, affecting the subsequent use. In the above-mentioned patent, the installation of the travel switch and the trigger baffle needs to be strictly controlled by manual installation precision, so as to realize the guarantee that the contact of the travel switch extends to the middle position between the upper and lower trigger plates, which is difficult to operate. Therefore, the utility model provides an electrolytic cell anode busbar dislocation detection device to solve the problems in the prior art. CONTENT OF THE UTILITY MODEL
