Abstract
Infrared temperature measurement observation window mechanism of automatically cleaning formula includes face structure down: quartz glass, quartzy observation window flange and gland, gaseous pipeline and the gas flow control flap etc. Of introducing. This mechanism can sweep with high -purity clean gaseous incessant pulsed observation window glass under the condition that does not influence the high temperature infrared radiation thermometer field of vision. Suspecting have under the condition of pollutant, can increase gas flow by automatic control, increaseing the dynamics of sweeping.
Description
Technical field
The present invention relates to contactless high-temperature measurement mechanism, particularly relate to the infrared measurement of temperature observation window mechanism on high-temperature atmosphere furnace.
Background technology
Produce at special ceramic material and particularly research and develop the high temperature that field usually will use 2000 ~ 3000 DEG C, in the temperature detection-control technology field of high temperature furnace, due to the expensive of pyrometer couple and service life short, so conventional contactless temperature-measuring in actual production, namely use high-temperature infrared temperature measurer observing and controlling temperature.
High-temperature infrared temperature measurer can be placed on outside stove, is measured the heat radiation of measured object, be converted to temperature value by observation window visor.This kind of thermometric mode directly can measure the surface temperature of heating object, but temperature measurement accuracy can be subject to the impact in the visual field.Particularly in high-temperature atmosphere furnace, gaseous exchange violent in stove can make pollutant be condensate on observation window visor, causes displays temperature to decline, actual object overtemperature.Therefore, a kind of mode of effective automated cleaning infrared viewing window is just needed aborning.
Summary of the invention
Object of the present invention, being to provide one effectively can self-cleaning infrared viewing window mechanism.
Self-cleaning infrared measurement of temperature observation window mechanism comprises structure below: quartz glass, quartz observing window flange and gland, gas inlet tube road and gas flow control valve etc.This mechanism when not affecting the high-temperature infrared temperature measurer visual field, can purge the viewing glass continual pulsed of high-purity clean gas.When suspection has pollutant, automatically can control to increase gas flow, strengthen purging effort.
The present invention due to design and mounting means reasonable, can to quartz glass effective cleaning.And owing to employing high-precision gas flow control valve and Programmable Logic Controller, can automatic when needed purge gas be regulated.
Accompanying drawing explanation
Fig. 1 is mechanical construction drawing of the present invention.
Fig. 2 is control circui schematic diagram of the present invention.
Detailed description of the invention
Self-cleaning infrared measurement of temperature observation window mechanism, comprises observation window gland 1, quartz glass 2, observation window flange 3, gas flow control valve 4, gas inlet tube road 5, Programmable Logic Controller 6, power controller 7, infrared radiation thermometer 8.
Have O type circle to seal between quartz glass 2 and observation window flange 3, observation window gland 1 is compressed by 4 hex bolts, has film dispersive pressure between observation window gland 1 and quartz glass 2, prevents quartz glass 2 pressure break.Gas flow control valve 4 air inlet connects gas cylinder, and gas outlet connects gas inlet tube road 5, passes into high-purity clean air.Gas inlet tube road 5 is L-shaped to be stretched in pipeline, is close to above pipeline, purges from the top down to quartz glass 2.Programmable Logic Controller 6 connects and controls the openings of sizes of gas flow control valve 4.Programmable Logic Controller 6 connects infrared radiation thermometer 8 simultaneously and power controller 7 judges the relation between target temperature and power output by program, when holding stage power increases above threshold value, can be judged as that pollutant increases causes thermometric to be forbidden, now automatically can increase gas flow control valve 4 opening, strengthen purging, prevent overtemperature.
