Description
Technical field
The utility model relates to a kind of device that adopts molten aluminum liquid interface in the radar Real-Time Monitoring aluminium cell, belongs to the aluminium cell technical field.
Background technology
In the aluminium cell production process, under the effect of powerful electromagnetic force, fused electrolyte in the groove/aluminium liquid interface can produce fluctuation, rotation, reach distortion, can cause secondary reaction increase, the current efficiency of electrolyzer to reduce, and can affect the normal production of aluminium cell when serious.Detect the interior aluminium liquid-electrolyte interface of aluminium cell and just seem particularly important, but the production environment of high temperature, highly corrosive in the electrolyzer, the sensor of most of contact all can't be worked in electrolyzer for a long time.Aluminium liquid interface when therefore at present not yet having good way and device can the on-line monitoring aluminium cell to produce.
In recent years radar ranging technical development is exceedingly fast, existing people begins the radar ranging technology is applied in the smelting iron and steel industry, lay the first stone for utilizing Radar Technology to detect the molten aluminum liquid interface, but because the singularity of environment in the aluminium cell: it is very big to have two-layer melt and corrodibility, and not yet the someone attempts adopting the interface of metal aluminium liquid in the Radar Technology Real-Time Monitoring aluminium cell to change.
Summary of the invention
The purpose of this utility model is, a kind of device that adopts molten aluminum liquid interface in the radar Real-Time Monitoring aluminium cell is provided, with overcome that prior art exists can not the on-line monitoring aluminium cell produce the time the deficiency at aluminium liquid interface.
The utility model is by the following technical solutions: antenna probes and radar signal/receiving trap are vertically mounted on the aluminium liquid top in the aluminium cell, antenna probes is connected with radar signal and receiving trap, radar signal and receiving trap are connected with signal processor, and signal processor is connected with computer control system.
2～40 antenna probes and radar signal and receiving trap are installed in each aluminium cell.
Antenna probes is installed on aluminium cell interior groove cover plate, bin wall or the special stand.
Antenna probes is vertically mounted on aluminium liquid top, apart from the position of aluminium liquid surface 800-1800mm.
Principle of work of the present utility model is that antenna probes is launched a branch of hertzian wave vertical sand shooting to the aluminium liquid surface of melting, and reflection.After receiving reflection wave by receiving trap, signal processor outside signal cable is transferred to groove, filter out noise, and the transmitted wave of other materials after, obtain the reflection wave on molten metal aluminium liquid surface, calculate the interfacial level value that its time delay can obtain metal aluminium liquid, to reach the purpose at the aluminium liquid interface in the Real-Time Monitoring aluminium cell.
The object that includes various material in the aluminium cell, but because the density of each material, the surface smoothness difference is large thereby to the different characteristics of reflection of radar waves situation.Behind the reflection wave of other materials, just obtain the transmitted wave on aluminium liquid surface in the filtering groove.
And antenna probes, radar signal and the receiving trap of 2～40 of some amounts are arranged in the subregion in aluminium cell, just can monitor the aluminium liquid interface real-time change value in the whole aluminium cell.
The changing conditions at the interior aluminium liquid interface of monitoring aluminium cell that the utility model energy is real-time, the convenient operation personnel understand and grasp the production law of aluminium cell, carry out timely production operation, can fully improve electrolyzer production energy-saving efficient, have wide prospect of the application.
