Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Wherein, furnace wall 100, horn mouth 110, burner hearth 120, igniter 130, pipeline 200, light sensing element 300, photoelectricity turn
Parallel operation 400, signal processor 500, air hose 600, blower 700, regulating valve 800, the first controller 910, second controller 920.
Specific embodiment
It elaborates below in conjunction with specific embodiment to the utility model.
As shown in Figure 1, a kind of boiler flame intelligent detection device provided in this embodiment can pass fugitive dust and Hei Jiao and light
Sensing unit 300 is isolated, while not influencing the function of light sensing element 300 again, and the present embodiment mainly includes furnace wall 100, pipeline
200, light sensing element 300, photoelectric converter 400, signal processor 500, air hose 600 and blower 700.Loudspeaker is set on furnace wall 100
Mouth 110, the thick mouth of horn mouth 110 is towards burner hearth 120, and the thin mouth of horn mouth 110 is connected to one end of pipeline 200, pipeline 200
The other end connect light sensing element 300, light sensing element 300 connect photoelectric converter 400, photoelectric converter 400 connection letter
Number processor 500.Light sensing element 300 can for ultraviolet light sensing tube or photodiode or lead sulfide photodetector or
Cadmium sulphide photoconductive cell, light sensing element 300 is used to perceive the flame in burner hearth 120, and the optical signal for perceiving flame is passed
To photoelectric converter 400, photoelectric converter 400 is for converting optical signals to electric signal, and signal processor 500 is for receiving light
The electric signal that electric transducer 400 is spread out of, and signal processing is done according to actual needs.
One end of air hose 600 is connected to the side wall of pipeline 200, and the other end of air hose 600 connects blower 700, air hose 600 with
The part and pipeline 200 that pipeline 200 is connected to are at an acute angle, and the outlet air end of air hose 600 is towards horn mouth 110.The wind that blower 700 is blown out
Successively pass through air hose 600 and pipeline 200, is finally blown in burner hearth 120 by horn mouth 110, as long as blower 700 is operating, burner hearth
Fugitive dust and Hei Jiao in 120 then cannot be introduced into pipeline 200, can not more contact with light sensing element 300, therefore this structure
It can be well protected light sensing element 300.This section that air hose 600 is connected to pipeline 200 is designed to and pipeline 200 by this structure
It is at an acute angle, make the air opening end of air hose 600 against horn mouth 110, this set defines the direction of wind, even if in this way, light
Sensing element 300 and the end junction sealing effect of pipeline 200 are undesirable, nor affect on the use of light sensing element 300, because
For air hose 600 air outlet direction for light sensing element 300 one of protective barrier of stroke, this design can also drop simultaneously
The seal request of low 300 junction of light sensing element, reduces the cost of manufacturing process.
It is further to note that the opening on furnace wall 100 is designed to horn mouth 110, it is on the one hand to consider that opening cannot
The detection effect for influencing light sensing element 300, is on the other hand not influence the outlet air of pipeline 200, therefore be just designed to external-open
Horn mouth 110.
Preferably, it can be equipped with regulating valve 800, on air hose 600 to adjust 600 air outlet of air hose according to actual needs
Wind-force.Still further, first controller 910 can be added, the first controller 910 respectively with regulating valve 800 and signal
Processor 500 connects, and the first controller 910 can be single-chip microcontroller or PLC, the first controller 910 mainly according to signal at
The size that the result that device 500 is fed back controls to adjust valve 800 is managed, because what signal processor 500 can be transmitted by light sensing element 300
Data analyze the case where 120 flame of flake hearth-tapping, then feed back to the first controller 910 according to flame conditions, and then control and adjust
Valve 800 is saved, coordinates the wind-force size of 600 air outlet of air hose mutually with the case where 120 flame of burner hearth, plays the mesh of intelligent control
's.The benefit of this design can ensure that the detection effect of light sensing element 300, such as, when the flame in burner hearth 120 is too small,
And the air outlet wind-force of air hose 600 is too big blows flame outward, this necessarily will affect the detection effect of light sensing element 300, because
This this preferred design can intelligently guarantee the effect of fire defector.
Preferably, a second controller 920 can also be increased, the second control connects with blower 700 and igniter 130 respectively
It connects.Second controller 920 is for solving the problems, such as step.Information whether igniting is sent to second controller by igniter 130
920, second controller 920 controls the unlatching of blower 700 according to the starting situation of igniter 130, such as says when igniter 130 opens
Dynamic, then second controller 920 controls blower 700 and starts, then for example says that then second controller 920 controls when igniter 130 extinguishes
Blower 700 continues to close after starting a period of time.The purpose of this design is to guarantee blower 700 in 120 flame of burner hearth
Start before full combustion, avoids fugitive dust or black coke caused by starting too late because of blower 700 from entering in pipeline 200, while guaranteeing fire
After flame sufficiently extinguishes, blower 700 just stops, and fugitive dust or black coke is also avoided to enter in pipeline 200.Second controller 920
Relay can be selected, naturally it is also possible to select single-chip microcontroller or PLC, if necessary, it might even be possible to by the first controller 910 with
Second controller 920 merges into a controller, to save cost.
The present embodiment not be isolated luminous energy with light sensing element 300 by fugitive dust and Hei Jiao, plays protection light sensing element 300
Effect, also acts as intelligent control, very humanized.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
