Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] As shown in the figure, the sealed protective window (103) with coating film on the back is placed obliquely in the purger (200), and its surface forms an angle of 60° with the optical axis of measurement; the front end of the small-diameter peep tube (300) has The ash leak tank (301); the tubular probe (100) equipped with the objective lens (101) and transmission optical fiber and the air pipe (202) for delivering high-pressure purge air flow are straight hard pipes, passing through the mounting flange (400) in parallel The two holes can be stretched forward and backward and clamped and fixed by the mounting flange (400).

[0018] A typical application example of the present invention is: measuring the coke cake temperature on an industrial coke oven coke holding car. The target temperature is high, the ambient temperature is high, high-density...

Abstract

The invention relates to an optical probe with a blower for an infrared thermodetector. The optical probe is characterized in that: an objective lens (101) and a transmission fiber (102) or an infrared sensor and a connecting wire thereof (102) are arranged in a tubular probe (100); a sealing protective window (103) is formed at the most front end of the tubular probe (100), and a film which reflects visible light and can be transmitted by infrared work spectrum is plated on the back of the protective window (103); the protective window is obliquely arranged in a blower (200); a high-pressure airflow can blow the surface of the protective window (103) through a pipeline (202) and an air duct (201) of the blower (200), and blows out through a minor-caliber peep tube (300) of which an ash leakage groove (301) is formed on the front end; the tubular probe (100) and the air duct (202) are straight parallel hard tubes, pass through two holes on an assembly flange (400), can flexibly adjust the distance with a target, and can be clamped and fixed by the assembly flange (400); the tail end of the hard tube of the tubular probe (100) is provided with a fiber connector (105) for externally connecting an extended armored fiber, or provided with a cable connector (105) for externally connecting an extended armored signal cable; and the tail end of the hard air duct (202) is provided with an air duct connector (203) for externally connecting an air feed pipeline.

Description

technical field [0001] The invention relates to a non-contact optical temperature measuring instrument, especially one that can realize effective purging and cleaning of the optical lens in the case of serious dust and water vapor interference and pollution, and the optical path purge air source cannot be purged for a long time. The optical probe of the infrared thermometer. Background technique [0002] The infrared thermometer measures the temperature by collecting the infrared radiant energy of the target through its optical system. During industrial online measurement, its measurement optical path and optical lens will be interfered and polluted by environmental dust and water vapor. Therefore, it is usually required to install an air purger and a peep tube to help clean the optical path at the front end of the optical probe, so as to keep the lens clean and eliminate dust and water vapor interference in the measurement optical path. [0003] Deficiencies and shortcomin...
