Abstract
The utility model relates to a molybdenum concentrates roasting dust leakage monitoring alarm system, which comprises a camera, a visual display screen, an infrared detector, a main control circuit, a first time-delay circuit, a second time-delay circuit, an alarm indicator light, a buzzing alarm, a fan close control relay and a display instrument, wherein the first and the second time-delay circuits are connected with the main control circuit, the alarm indicator light is controlled through the main control circuit, the buzzing alarm is controlled through the first time-delay circuit, the fan close control relay is controlled through the second time-delay circuit, and the display instrument is controlled by the main control circuit, works at the same time with the alarm indicator light, and is used to detect whether leaking materials. The molybdenum concentrates roasting dust leakage monitoring alarming system solves the problem that materials leak because a cloth bag dust collector leaks and the electrical pressure of an electric field dust collector reduces, thereby causing severe economic losses. The molybdenum concentrates roasting dust leakage monitoring alarming system has the advantages of high sensitivity and excellent reliability, can achieve on-line real time monitoring, can achieve visual monitor, instrument monitor and acousto-optic alarm, further can be linked with a fan, automatically controls the fan to open and close, precludes the loss of leaking dust, and is suitable to monitor molybdenum sulfide and molybdenum oxide dust to leak when rotary kilns roast molybdenum concentrates.
Description
Technical field
The utility model is particularly related to a kind of calcining molybdenum ore concentrate dust leakage monitoring alarm control system.
Background technology
Molybdenum concntrate drops into rotary kiln baking, and a kiln tail dusty gas part enters kiln tail blower fan through kiln tail ash bin, rotoclone collector, electric field dust-precipitator, sends into desulphurization system; Kiln tail dusty gas another part is sent into desulphurization system through flash dryer, bagroom, flash distillation blower fan.Cause material to be revealed because bagroom is revealed and electric field dust-precipitator voltage descends, cause serious economy loss.
The utility model content
The technical problems to be solved in the utility model provides a kind of calcining molybdenum ore concentrate dust leakage monitoring alarm control system whether the molybdenum concntrate dust leaks that detects, and can solve calcining molybdenum ore concentrate system material leakage problem, avoids causing economic loss.
The calcining molybdenum ore concentrate dust leakage monitoring alarm control system that the utility model relates to comprises camera and visual display, Infrared Detectors, be used for controlling camera and Infrared Detectors work and according to the governor circuit of Infrared Detectors testing result output control signal, first delay circuit and second delay circuit of the governor circuit that was connected with governor circuit control, alarm lamp by governor circuit control, buzzer siren by the control of first delay circuit, by the blower fan closing control relay of second delay circuit control, control the Displaying Meter that is used for detecting the material whether leakage is arranged of working simultaneously by governor circuit with alarm lamp.
The utility model utilizes video, infrared monitor control in conjunction with the distinctive performance of material, can find in time that the dust of cloth bag or electric field dust-precipitator leaks material, effectively avoids the leakage of molybdenum concntrate on flash distillation fan outlet tube road and kiln tail fan outlet tube road.Highly sensitive, good reliability can realize on-line real time monitoring, not only can realize visual monitoring, instrument monitoring, sound and light alarm, can also be chain with blower fan, control fan switch automatically, stop dust and leak the material loss, monitoring molybdenum sulfide, molybdenum oxide dust are revealed when being applicable to the rotary kiln baking molybdenum concntrate.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model.
Among the figure: camera 1, Infrared Detectors 2, governor circuit 3, alarm lamp 4, the first delay circuits 5, buzzer siren 6, the second delay circuits 7, control relay 8, Displaying Meter 9, display screen 10.
The specific embodiment
This calcining molybdenum ore concentrate dust leakage monitoring alarm control system comprises camera 1 and visual display 10, Infrared Detectors 2, be used for controlling camera 1 and Infrared Detectors 2 work and according to the governor circuit 3 of Infrared Detectors 2 testing results output control signal, the governor circuit 3 that was connected with governor circuit 3 is controlled first delay circuit 5 and second delay circuit 7 of work, alarm lamp 4 by governor circuit 3 controls, by the blower fan closing control relay 8 of second delay circuit 7 control, detect the Displaying Meter 9 of the material whether leakage is arranged and by the buzzer siren 6 of first delay circuit, 5 controls by being used for of working simultaneously of governor circuit 3 controls and alarm lamp 4.First, second delay circuit 5,7 delay times are adjustable and second delay circuit, 7 delay times greater than first delay circuit, 5 delay times, described Displaying Meter 9 can adopt uA table.
During installation, the infrared probe of camera 1 and Infrared Detectors 2 can be installed directly on flash distillation fan outlet tube road and kiln tail fan outlet tube road, blower fan closing control relay 8 normally-closed contacts are connected with the flash distillation fan switch.Molybdenum concntrate is dropped into rotary kiln baking, and a kiln tail dusty gas part enters kiln tail blower fan through kiln tail ash bin, rotoclone collector, electric field dust-precipitator, sends into desulphurization system; Kiln tail dusty gas another part is sent into desulphurization system through flash dryer, bagroom, flash distillation blower fan.When closing governor circuit 3 power supplys and connect camera 1 and Infrared Detectors 2 switches, pipeline tail end situation feeds back to display screen 10 by camera 1, can directly observe the leakage whether material is arranged on display screen 10.If have the leakage of material and dusty gas concentration to reach 0.01～0.05g/m at the pipeline tail end
3The time, then Infrared Detectors 2 sends signal, gives governor circuit 3 signal feedback, and governor circuit 3 output control signals make alarm lamp 4 and 5 work of first delay circuit, bright, the pointer fluctuation of red light on the Displaying Meter 9 simultaneously, even drop to zero-bit; First delay circuit 5 is delayed time to setting-up time (is example with 2s), if the leakage (revealing in order to avoid the iron sheet that pipeline comes off and other foreign material are mistaken as molybdenum concntrate) of material is arranged within 2s continuously, makes buzzer siren 6 and 7 work of second delay circuit.The leakage of material if within 10s, exist, by second delay circuit, 7 delayed startup blower fan closing control relays 8, blower fan closing control relay 8 normally-closed contacts of connecting with the flash distillation fan switch are disconnected, blower fan will cut out automatically, avoid during leaking material unmanned patrol in the Control Room and cause a large amount of materials to be revealed.
When Displaying Meter 9 pointers fluctuations, even when dropping to zero-bit, should check at first that the dustproof glass on the pyroscan 2 has free from dust, behind the dust out, red light goes out, and it is normal that Displaying Meter 9 pointers recover, and presses the releasing alarm switch, recovers normal detected state.Still find that red light is bright, Displaying Meter 9 pointers fluctuations, even when dropping to zero-bit and buzzer siren 6 and reporting to the police, illustrate and Lou expected phenomenon, should check cloth bag or electric field dust-precipitator immediately.
