Description
Technical field
The technical field of detection device is the utility model is related to, especially a kind of sonic detection blast furnace material distribution chute failure dress
Put.
Background technology
In blast furnace ironmaking production, the accidents such as the mill of top distributing chute leaks, is broken, coming off have a strong impact on normal operation.
The furnace condition disorder caused by distributor chute failure all occurred for domestic Duo Jia iron companies, and What is more, because distributor chute comes off
Fail to find in time, cause the great serious accident of gobbed up.
At present, in the industry for distributor chute failure determination methods be first to some be possible to cause the working of a furnace fluctuates because
Element, such as raw material and fuel quality, weighing error, slag crust slides, cooling device leak carries out investigation negative one by one；In addition, it is also necessary to
To substantial amounts of operation of blast furnace parameter carry out comprehensive analysis, the possibility of failure is inferred, finally still need to damping down pass through it is direct
The method of observation determines, so as to be smoothed out causing influence to production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of industrial production environment that can adapt to complexity, made a living
A kind of sonic detection blast furnace material distribution chute failed equipment for being smoothed out providing Reliable guarantee of production.
Solve above-mentioned technical problem technical scheme be：
A kind of sonic detection blast furnace material distribution chute failed equipment, including place the cross temperature frame, sound pick-up, biography of thermocouple
Sensor, PLC control cabinet and industrial computer, described cross temperature frame are arranged in furnace roof cover, four ends part of cross temperature frame
Do not extend to outside furnace roof cover, described sound pick-up is connected in cross temperature frame end portion, and described sensor passes through optical fiber and PLC
Switch board connects, and described PLC control cabinet is connected with industrial computer.
The sound pick-up is fixed on above cross temperature frame.
PLC control cabinet includes CPU templates, power template, digital quantity analog input and output template, power distribution equipment.
PLC control cabinet is connected with sensor, and HMI connections are monitored by the operation of address card and industrial computer.
The operation monitoring HMI of industrial computer includes hardware and picture writes software.
The beneficial effects of the utility model are：The cross temperature frame, sound pick-up, PLC that placed the thermocouple control set
The parts such as cabinet, it is possible to different sound waveforms is produced according to different failure situations, is judged using the difference of sound waveform
The production status of blast furnace roof material distributing, so as to the method for accurate judgement distributor chute failure, the influence of failure is minimized, prevented
Only trigger serious accident, have and be easy to maintenance, low cost, high accuracy, efficient advantage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows：Furnace roof cover 1, distributor chute 2, furnace charge 3, cross temperature frame 4, sound pick-up 5, sensor 6, PLC
Switch board 7, industrial computer 8.
Embodiment
A kind of sonic detection blast furnace material distribution chute failed equipment as shown in Figure 1, the cloth of furnace charge 3 is in distributor chute 2.
When distributor chute 2 does not break down, the inclination angle of distributor chute 2 is certain, furnace charge 3 and the position of collision of cross temperature frame 4
Fixed, furnace charge 3 collides the sound width numerical value that cross temperature frame 4 is sent and fixed, and sound pick-up 5 receives voice signal and passes through sensing
Device 6 is sent in PLC control cabinet 7 by optical fiber, is passed to afterwards in the system of industrial computer 8, the time is furnace charge 3 and cross temperature
The time that the collision of frame 4 produces sound is fixed numbers t, and furnace charge 3 is scattering into blast furnace and ten in distributor chute 2 by setting track
Word temperature measuring rack 4 carries out collision and forms a series of fixed numbers t, is shown in HMI pictures and forms normal sound wave curve A.
When distributor chute 2 is broken, distributor chute 2 furnace charge 3 and position of collision of cross temperature frame 4 under the conditions of same inclination angle is different
Often, furnace charge 3 collides the sound width numerical value change that cross temperature frame 4 is sent, then can show that furnace charge 3 collides with cross temperature frame 4
Produce the time numerical value change of sound；Sound pick-up 5 receives voice signal and is sent to PLC controls by optical fiber by sensor 6
In cabinet 7, pass to afterwards in the system of industrial computer 8, the time is the time that furnace charge 3 collides generation sound with cross temperature frame 4 to be
t1, furnace charge 3 in distributor chute 2 by not fixation locus be scattering into blast furnace and cross temperature frame 4 carry out collision formed it is a series of
Not fixed numbers t1, it is shown in the sound wave curve A formed in HMI pictures1Different from normal sound wave curve A, system alarm.
Leaked when distributor chute 2 is ground, the part of furnace charge 3 by distributor chute 2 it is normal when collide with cross temperature frame 4, separately
Hole of some furnace charge 3 through mill leakage is fallen directly into stove, and furnace charge 3 collides the sound width numerical value that cross temperature frame 4 is sent
Change, sound pick-up 5 receive voice signal and are sent to by sensor 6 by optical fiber in PLC control cabinet 7, pass to industry control afterwards
In the system of machine 8, the time is furnace charge 3, and to produce time of sound with the collision of cross temperature frame 4 be t2, furnace charge 3 is in distributor chute 2
In be scattering into by not fixation locus in blast furnace and cross temperature frame 4 carries out collision and forms a series of not fixed numbers t2, display
The sound wave curve A formed in HMI pictures2Different from normal sound wave curve A, system alarm.
