Smelting process, there is strict requirements to furnace charge, for example, enter the furnace charge that furnace size is uniform, furnace size is less than normal, add
In powder to screen out and furnace charge in objectionable impurities content will less wait.Varigrained crude fuel loads blast furnace, and furnace charge has
Filling effect, reduces the space of furnace charge, poor air permeability.And epigranular can then improve furnace charge air permeability, ore is improved indirect
Reduction degree.This energy-conservation to blast fumance, high yield have positive meaning.
At present, the grain size analysis of general blast furnace burden, is mostly using the easy mechanical means of tradition.For example, using sample
Spoon or bucket-shaped container, sample once at regular intervals, deliver to screening machine classification, each grade feeding weighing funnel mistake for separating
Scale, by the distribution situation for calculating furnace size size.As can be seen here, the grain of furnace charge is carried out using traditional method of inspection
Degree analysis, it is not only cumbersome time-consuming and extremely inefficient, it is impossible to meet the requirement of the big production of modernization.Therefore, it is badly in need of realizing
Line, in real time, efficiently detection mode.
It is online, in real time, efficiently to realize with developing rapidly for industrial video technology and computer graphics disposal technology
Detection is provided may.Just because of this, adopted for carrying out image to the furnace charge on belt conveyor using digital image processing techniques
During collection, treatment, if can clearly, comprehensively and accurately to live material carry out IMAQ to successive image treatment
With vital influence.
Utility model content
The purpose of this utility model is to provide one kind and can realize carrying out blast furnace burden in line material collection, monitoring and locating
The blast furnace burden granularity monitoring system of reason.
Therefore, technical solutions of the utility model are as follows：
A kind of blast furnace burden granularity monitoring system, including be arranged on imaging device above conveying equipment and positioned at it is described into

Further, the lighting source is LED light source, and it is arranged on the symmetrical low angle polishing in imaging device both sides；Institute
It is 30~60 ° to state the angle between the beam center of LED light source and vertical direction.
Further, the imaging device includes at least one industrial camera, between the adjacent industrial camera
Level interval is 0.8m；Camera lens is installed every industrial camera front end, the industrial camera and the camera lens hang down
Directly set down.
Further, the imaging device outside is also set with gas sweeping type protective jacket, it is ensured that imaging device and illumination
Light source stabilization normal work in the environment of dust high；Wherein, blowing medium is compressed air.
Further, the system is also included for imaging device and lighting device provide the field control case of stabilized power source and set
Put the control system in control room；The control system includes being used to analyze and process the industrial computer of video image, being used for
Display real-time image acquisition and treatment after data display device, for control field control case, industrial computer and display dress
The indoor control cabinet put, acoustic-optic alarm and the signal conversion being arranged between industrial computer and acoustic-optic alarm
Device.
The blast furnace burden granularity monitoring system is improved and adjusts by imaging device and lighting apparatus, realizes to passing
The high-quality of the original image of the blast furnace burden in equipment is sent to gather, for the analysis of follow-up blast furnace burden size distribution image provides clear
Clear, complete etc. high-quality original image.
Brief description of the drawings
Fig. 1 is the structural representation of blast furnace burden granularity monitoring system of the present utility model；
Fig. 2 is that the imaging device and lighting source of blast furnace burden granularity monitoring system of the present utility model are arranged at conveying and set
Standby upper structural representation；
Fig. 3 is the side structure schematic diagram of Fig. 2.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the utility model, but following embodiments are right absolutely not
The utility model has any limitation.
As shown in figure 1, the blast furnace burden granularity monitoring system sets imaging device 1, lighting source 2, scene at the scene
Control cabinet 3, and it is arranged on industrial computer 4, display device 5, indoor control cabinet 6, the harmony of signal adapter 7 in control room
Light alarm device 8.
As shown in figures 2-3, imaging device 1 and lighting source 2 are arranged on blast furnace burden conveying equipment top；Blast furnace burden
It is delivered in State of Blast Furnace using feed belt, imaging device 1 is arranged on the surface of feed belt, and lighting source 2 is less than institute
State and be arranged oppositely at imaging device 0.4m, its lighting angle is 45 °；Specifically, the lighting source 2 selects HQ-SD-W400F
Floodlight, it meets 40000 ± 5%LM of luminous flux, and colour temperature is the requirement of 5500~6000K.
Herein it is emphasized that when carrying out IMAQ, the illumination on raw material is extremely important, to reduce external light source
