Abstract
The invention relates to a furnace arch slab alarm device. The furnace arch slab alarm device comprises a detecting device and an alarm, wherein the detecting device is arranged on a furnace, the alarm is connected with the detecting device, and the detecting device is a laser correlation sensor. The laser correlation sensor comprises a laser emitting end and a laser receiving end, wherein the laser emitting end is fixedly installed on a furnace inlet, and the laser receiving end is fixedly installed on a furnace outlet. The furnace is provided with observing holes for positioning the transmission direction of a laser. The laser receiving end is connected with the alarm through a signal wire. The observing holes are located in installing structures fixedly installed at the two ends of the furnace. The accurate arch slab alarming is achieved by adopting the laser correlation sensor, the furnace arch slab alarm device can work in a high-temperature environment, has a stable detecting line and is capable of giving a timely and accurate alarm, and maintaining cost is reduced.
Description
Technical field
The present invention 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 adopted at present has software timer alarm and infrared sensor to report to the police.The software timer alarm mode, be to determine the 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.False alarm, can, because being subject to running time technological requirement to affect the instability generation error, occur or report to the police not in time in software timer alarm.And infrared sensor is reported to the police and can't at high temperature be used.Burner hearth cold conditions and hot meeting make the 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.
Summary of the invention
The object of the present invention is to provide a kind of burner hearth arch bar warning device, this warning device realizes accurately that by the laser-correlation sensor arch bar reports to the police, but steady operation is at burner hearth under hot and cold conditions.The present invention can realize reporting to the police reliably in time, has reduced maintenance cost.
For achieving the above object, the present invention has adopted following technical scheme: a kind of burner hearth arch bar warning device comprises that the checkout gear be located on burner hearth and the alarm be connected with checkout gear, described checkout gear are the laser-correlation sensor.
Described laser-correlation sensor comprises the Laser emission end that is fixedly arranged on the burner hearth import and is fixedly arranged on the laser pick-off end of furnace outlet.
Described burner hearth is provided with the peep hole for the 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 the burner hearth two ends.
Advantage of the present invention:
(1) the present invention adopts the laser-correlation sensor to realize that arch bar is reported to the police accurately.The characteristics such as the 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 can't meet the omnidistance requirement detected.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 present invention is provided with peep hole on the mounting structure of burner hearth, after the laser of transmitting terminal emission passes through burner hearth, use the erythema of the cross positioning function locking transmitting terminal of the peep hole on the receiving terminal mounting structure, set up stable a, detection line accurately above the saggar of transmission.By the setting of peep hole, accuracy of detection and stability have been improved.
(3) accuracy of detection of the present invention is high, when the arch bar sign is arranged, just sends alarm signal, avoids causing larger destruction, has reduced maintenance cost.
The present invention can be in hot environment steady operation, there is stable detection line, warning promptly and accurately can be provided, reduced the cost of overhaul.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
A kind of burner hearth arch bar warning device as shown in Figure 1, comprise the checkout gear be located on burner hearth 3 and the alarm 5 be connected with checkout gear, and specifically, checkout gear is the 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, the 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 the locating laser transmission direction.Specifically, peep hole is positioned on the mounting structure 1 that is installed in the burner hearth two ends.By after burner hearth 3, use the erythema of the cross positioning function locking transmitting terminal 2 of the peep hole on the receiving terminal mounting structure when the laser of Laser emission end 2 emission, set up stable a, detection line accurately above the saggar 4 of transmission.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 the 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 the prompting workman is overhauled in time, avoids causing larger loss.
Concrete use procedure of the present invention is as follows:
Arch bar warning device of the present invention adopts the laser-correlation sensor to be monitored the saggar transmitting procedure.At first pass through burner hearth by the transmitting terminal Emission Lasers, 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 the saggar normal transmission, receiving terminal can receive the laser of transmitting terminal emission, alarm free signal.When the saggar body, not during normal transport, the laser of transmitting terminal emission is had the saggar of arch bar sign to block, and can't arrive receiving terminal, and now receiving terminal sends alarm signal by holding wire to alarm.After receiving alarm signal, workman's arrestment work immediately, carry out that saggar is ajusted or the burner hearth maintenance.The present invention 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 invention is limited, and designs under the prerequisite of spirit not breaking away from the present invention, and various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection domain of the claims in the present invention book.
