Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, it is structural representation of the present utility model, a kind of hot galvanizing line zinc of the utility model liquid liquid level emasuring device, comprise linker 3 and at least 2 radar level gauges, described linker 3 one end connects zinc liquid pool bottom zinc nose 2 by pipeline, it is outer and establish and observe well 14 that the other end extends to zinc pot 1 liquid level, and described radar level gauge 4,5 is arranged on above the zinc pot zinc liquid level 8 observed above well 14 and outside zinc nose 2 respectively, and the output terminal of radar level gauge 4,5 connects galvanizing control system respectively.
Distance between described radar level gauge 4,5 and zinc liquid level 9,8 is 1.5 ~ 2.5m, is provided with metallic cylinder 10 between radar level gauge 4,5 and zinc liquid level 9,8.
Described galvanizing control system establishes Human machine interface, and connects radar level gauge 4,5 by PLC, and measurement result can show on a display screen.
As shown in Figure 1; band steel 13 introduces zinc pot 1 through zinc nose 2; before zinc liquid pump 6 is installed; the zinc gray in process zinc nose 2 and cadmia will be shut down after production line runs a period of time; after zinc liquid pump 6 is installed; the zinc gray stored in zinc nose 2 in ash-pit 11 and the floating clinker groove 12 of row and cadmia can be discharged at any time, band steel 13 ratio of defects obviously declines, but row's zinc speed of zinc liquid pump 6 and duty need to monitor adjustment at any time.
The principle of work of a kind of hot galvanizing line zinc of the utility model liquid liquid level emasuring device is: by installing linker 3, zinc liquid in zinc nose 2 is drawn out in the observation well 14 outside zinc nose 2, then above observation well 14, install radar level gauge 1, the zinc liquid liquid level 9 measured in gained observation well 14 is highly equivalent to zinc liquid liquid level 7 height in zinc nose 2.Then radar level gauge 25 is installed in zinc pot 1 pot edge outside zinc nose 2, measures outer zinc pot zinc liquid liquid level 8 height of zinc nose 2.Measurement result is sent to the analog quantity template of PLC ET200M slave station by analog quantity channel, by Ethernet is sent to HMI picture on after carrying out the linearization process of dimension by PLC programming.
In order to avoid the interference of cadmia, spy is at radar level gauge 1 and observe well zinc liquid liquid level 9, install metallic cylinder 10 between radar level gauge 25 and zinc pot zinc liquid liquid level 8, makes radar appearance accurately, without interruption; The optimum height of metallic cylinder 10, at about 1.9 meters, can completely cut off the high temperature of zinc liquid liquid level completely, avoid high temperature to the infringement of radar level gauge.
Seeing Fig. 2, is that zinc liquid liquid level calculates schematic diagram.In zinc liquid liquid level tool=H-D (mm) formula: H-radar level gauge is to the overall height of container bottoms; The actual measured value (distance between radar level gauge and actual zinc liquid liquid level) of (corresponding radar level gauge 1 points to and observes well 14 floor height, and corresponding radar level gauge 25 points to zinc pot 1 floor height) D-radar level gauge; In figure, tool 1 represents maximum level, corresponding analog output 20mA; Tool 2 represents minimum level, corresponding analog output 4mA.
The actual liquid level value of measurement sends in the analog input of PLC ET200M slave station by 4 ~ 20mA signal by radar level gauge 1, radar level gauge 25, then carry out the linearization process of dimension in PLC after, HMI picture is sent to again by the Ethernet between PLC and HMI, zinc liquid liquid level in zinc nose 2 and zinc nose 2 outer zinc pot 1 zinc liquid liquid level are presented on screen, operating personnel can according to row's zinc speed of the compared with control zinc pump between two numerical value, and can to the working state real-time monitoring of zinc liquid pump 6.
