Molten iron liquid level device is surveyed to infrared ray

The utility model relates to a blast furnace ironmaking technology field especially relates to a molten iron liquid level device is surveyed to infrared ray. Including infrared range finder, cooling dust collector, strutting arrangement, solenoid electric valve, PLC controller. Does not loosen easily. Infrared range finder passes through the bolt fastening on cooling dust collector's base, and its probe is placed in keeping off the dirt cover intraductally, and the cooling dust collector fix on strutting arrangement. Through the compressed air dust removal, avoided the infrared ray to survey and disturbed by the smoke and dust when molten iron liquid level indicator is measured, improved measurement accuracy, through compressed air's the cooling that sweeps, avoided the infrared ray to survey molten iron liquid level indicator yin gaowen and damage, and it is with low costs, it is convenient to maintain. 本实用新型涉及高炉冶炼技术领域，尤其涉及种红外线测铁水液面装置。包括红外线测距仪、冷却除尘装置、支撑装置、电磁控制阀、PLC控制器。冷却除尘装置由底座、挡尘套管、法兰、冷却除尘给风管构成，底座焊接于挡尘套管上端，
