Abstract
The invention discloses a steel ladle clearance monitoring device comprising a support arranged at a production site, a half-fixed holder arranged on the support, a protecting cover with a camera inside arranged on the half-fixed holder, a controlling box arranged at the production site, an indoor cabinet arranged in a control room, an industrial computer used for processing collected video signals, a display device used for displaying collected real-time video images and processing results from the industrial computer, and an alarming device used for generating alarming signals. With the monitoring device provided by the invention, real-time steel ladle clearance monitoring can be realized, collected video signals can be analyzed in time, and the video images and analysis results can be displayed on the display device. When steel ladle clearance reaches a preset value, a feedback signal will be automatically outputted by a system, and the alarming device performs automatic alarming.
Description
Technical field
The present invention relates to metallurgical technology field, particularly relate to a kind of headroom monitoring device of ladle.
Background technology
In the converter steelmaking production process, require to greatest extent holding molten steel of ladle, and can not overflow, if the ladle overhead clearance is excessive, will reduce the dress steel amount of ladle, reduce the tap of converter, make the Efficiency Decreasing of converter steelmaking, the energy consumption of unit output of steel rises; If the ladle overhead clearance is too small, just easily make ladle that the accident of excessive slag or excessive steel occurs, in the ladle transportation security incident occurs perhaps, threaten the life security of enterprise staff.Therefore, the ladle overhead clearance of controlling well just seems very important, this for guarantee production safety, reducing production costs and increasing economic efficiency all has very important significance.
At present, the control of domestic enterprise's ladle overhead clearance during to converter tapping nearly all is to adopt traditional artificial observation method closely to estimate, and yet there are no other advanced detection means.Although can solve certain practical problems, there is following hidden trouble in traditional artificial observation method:
1. operative employee's safety does not guarantee.Because the surrounding enviroment of converter steelmaking are very abominable, temperature is high, dust is large and noise is large, the situation that molten steel or slag splash may occur during converter tapping in addition, is breakneck so the operative employee observes the ladle overhead clearance to nearby, and personal injury accident very easily occurs.
2. the control of ladle overhead clearance is unstable.Because various human factors, for example: difference between people's healthy state, emotional factor, physiological change and the Different Individual etc. usually can cause observations different, thereby cause the control of ladle overhead clearance unstable.
3. signal feedback is slow, can not effectively control the overhead clearance of ladle.Because the operative employee is after observation nearby, the result goes to control converter and whether lifts stove according to the observation again, usually causes lifting stove and lags behind, and causes the ladle overhead clearance too small, even causes the situation of ladle overflow to occur, and leads to work safety accident.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of can be long-range, the monitoring device of Real-Time Monitoring ladle overhead clearance.
For this reason, technical scheme of the present invention is as follows:
A kind of ladle headroom monitoring device comprises: be installed in the production scene support, be installed in semifixed The Cloud Terrace on this support, be installed on the semifixed The Cloud Terrace and the inner protecting jacket that pick up camera is housed, be arranged on the production scene controlling box, be arranged on the indoor machine cabinet watch-keeping cubicle in, be used for industrial computer that the vision signal that gathers is processed and in the indicating meter that shows the real-time video picture that gathers and industrial computer result and for the warning device that sends guard signal.
Described pick up camera is the technical grade pick up camera, described protecting jacket is air-cooled protecting jacket, and its front end has the aciculiform aperture, in this aperture pinhole lens is installed, be connected with the pressurized air that protecting jacket is cooled off in the interlayer of this protecting jacket, pinhole lens purges by pressurized air.Described compressed-air actuated pressure is 0.40～0.6MPa, temperature in≤35 ℃.
Be provided with in the described field control case and be used to pick up camera that steady operation power supply power control unit is provided, be used for the ball valve of control compressed air-feed and gas flow and the communication equipment that is used for video signal transmission.
Described communication equipment comprises for the video optical multiplexer of transmission of video and other data, is used for the terminal box of optical cable fixed protection, tail optical fiber welding and socket switching and is used for the optical cable that signal transmits.
Ladle headroom monitoring device of the present invention can Real-Time Monitoring ladle headroom, in time the vision signal that collects is analyzed, and video image and analytical results be presented on the indicating meter, when the ladle overhead clearance reaches set(ting)value, system can automatic output feedback signal, simultaneously warning device automatic alarm.
Description of drawings
Fig. 1 is the structural representation of ladle headroom monitoring device of the present invention;
Fig. 2 is the schematic diagram that shows the ladle headroom.
Embodiment
Below in conjunction with accompanying drawing ladle headroom monitoring device of the present invention is elaborated.
As shown in Figure 1, ladle headroom monitoring device of the present invention mainly is comprised of support 1, semifixed The Cloud Terrace 2, protecting jacket 3, controlling box 4, indoor machine cabinet 5, indicating meter 6, industrial computer 7 and warning device 8.
Protecting jacket 3 is air-cooled pinhole arrangement, and its front end pinhole diameter is
Technical grade pick up camera and pinhole lens are installed in the protecting jacket, guarantee the normal Working environment of pick up camera and prevent camera lens knot ash by compressed-air actuated purging.Compressed air pressure is 0.40～0.6MPa, temperature in≤35 ℃.
Be provided with video optical multiplexer, power-supply controller of electric, control ball valve and video change-over panel in the controlling box 4.Because the environment around the converter steelmaking is very abominable, comprises various electromagnetic interference sources etc., so the monofilm optical cable has been adopted in the transmission of vision signal.
In the industrial computer 7 video image processing system is installed, carry out analyzing and processing in order to the ladle headroom picture to the camera acquisition of front end, when the ladle overhead clearance reached the technique numerical value of setting, system can automatic output feedback signal, simultaneously warning device automatic alarm.Feedback signal also can be given to the PLC Controlling System of converter, realizes the tapping auto-control.
As shown in Figure 2, the upper limb of ladle and the vertical range d of liquid steel level are the ladle headroom, according to the image ratio of the image that gathers, the ladle headroom that shows in the image can be converted into actual range.When liquid level arrives certain altitude, detect in real time the variation of molten steel liquid level, can calculate the actual clearance of ladle.
