Description
Technical field
The utility model relates to a kind of burner hearth arch bar warning device.
Background technology
Saggar in straight way stove burner hearth, in process, can upwards arch upward because of unpredictable factor, causes burner hearth to be damaged, and causes larger loss.The burner hearth arch bar type of alarm adopting at present has software timer alarm and infrared sensor to report to the police.Software timer alarm mode, is to determine time of fire alarming interval running time by computing equipment, when furnace outlet has saggar out, by zero clearing writing time, starts reclocking simultaneously.If within preset time, furnace outlet does not have saggar out, is considered as occurring arch bar and reports to the police., can, because being subject to running time technological requirement to affect instability generation error, there is false alarm or report to the police not in time in software timer alarm.And infrared sensor is reported to the police and cannot at high temperature be used.Burner hearth cold conditions and hot meeting make sensor correspondence position have deviation, and High Temperature Gas fails to be convened for lack of a quorum and cause infrared sensor light to reflect, and false alarm occurs or do not report to the police.
Utility model content
The purpose of this utility model is to provide a kind of burner hearth arch bar warning device, and this warning device is realized arch bar accurately by laser-correlation sensor and reported to the police, can steady operation at burner hearth under hot and cold conditions.The utility model can be realized in time and reporting to the police reliably, has reduced maintenance cost.
For achieving the above object, the utility model has adopted following technical scheme: a kind of burner hearth arch bar warning device, comprises that the checkout gear being located on burner hearth and the alarm being connected with checkout gear, described checkout gear are laser-correlation sensor.
Described laser-correlation sensor comprises the Laser emission end that is fixedly arranged on burner hearth import and the laser pick-off end that is fixedly arranged on furnace outlet.
Described burner hearth is provided with the peep hole for locating laser transmission direction.
Described laser pick-off end is connected with alarm by holding wire.
Described peep hole is positioned on the mounting structure that is installed in burner hearth two ends.
Advantage of the present utility model:
(1) the utility model adopts laser-correlation sensor to realize arch bar warning accurately.The features such as laser-correlation sensor has far firing range, speed is fast, precision is high, strong interference immunity.Hearth body is very long, and short-range ray cannot meet the omnidistance requirement detecting.The laser range of laser-correlation sensor emission is far away, speed is fast, can guarantee that whole-process high-efficiency detects, and has improved accuracy of detection.Laser-correlation sensor strong interference immunity, can, at steady operation under hot environment, reduce false alarm rate.
(2) the utility model is provided with peep hole on the mounting structure of burner hearth, when the laser of transmitting terminal transmitting is by after burner hearth, use the erythema of the cross positioning function locking transmitting terminal of the peep hole on receiving terminal mounting structure, above the saggar of transmission, set up stable a, detection line accurately.By the setting of peep hole, accuracy of detection and stability have been improved.
(3) the utility model accuracy of detection is high, when having arch bar sign, just sends alarm signal, avoids causing larger destruction, has reduced maintenance cost.
The utility model can be in hot environment steady operation, there is stable detection line, warning promptly and accurately can be provided, reduced the cost of overhaul.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of burner hearth arch bar warning device as shown in Figure 1, comprises the checkout gear being located on burner hearth 3 and the alarm 5 being connected with checkout gear, and specifically, checkout gear is laser-correlation sensor.Laser-correlation sensor far firing range, speed are fast, can guarantee that whole-process high-efficiency detects, and has improved accuracy of detection.Laser-correlation sensor strong interference immunity, can, at steady operation under hot environment, reduce false alarm rate.
Further, laser-correlation sensor comprises the Laser emission end 2 that is fixedly arranged on burner hearth 3 imports and the laser pick-off end 6 that is fixedly arranged on burner hearth 3 outlets.
Further, burner hearth 3 is provided with the peep hole for locating laser transmission direction.Specifically, peep hole is positioned on the mounting structure 1 that is installed in burner hearth two ends.When the laser of Laser emission end 2 transmitting is by after burner hearth 3, use the erythema of the cross positioning function locking transmitting terminal 2 of the peep hole on receiving terminal mounting structure, above the saggar 4 of transmission, set up stable a, detection line accurately.By the setting of peep hole, accuracy of detection and stability have been improved.
Further, laser pick-off end 6 is connected with alarm 5 by holding wire.When saggar 4 has arch bar sign, laser pick-off end 6 does not just receive the laser signal that Laser emission end 2 sends.6, laser pick-off end feeds back to information alarm 5 in time, and prompting workman overhauls in time, avoids causing larger loss.
Concrete use procedure of the present utility model is as follows:
Arch bar warning device of the present utility model adopts laser-correlation sensor to monitor saggar transmitting procedure.First by transmitting terminal Emission Lasers, pass through burner hearth, utilize the signal of the cross positioning function locking transmitting terminal of receiving terminal peep hole, above saggar, certain position is set up detection line.Then when saggar normal transmission, receiving terminal can receive the laser of transmitting terminal transmitting, alarm free signal.When saggar body is not during normal transport, the laser of transmitting terminal transmitting is had the saggar of arch bar sign to block, and cannot arrive receiving terminal, and now receiving terminal sends alarm signal by holding wire to alarm.Receive after alarm signal, workman's arrestment work immediately, carries out that saggar is ajusted or burner hearth maintenance.The utility model can be in hot environment steady operation, there is stable detection line, warning promptly and accurately can be provided, reduced the cost of overhaul.
Scope of the present utility model limits; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
