Abstract
The utility model relates to a high-temperature metal liquid temperature probe, which belongs to the field of an instrument. A scope glass cup body is arranged in one end of a steel cylinder jacket and a screw plug is arranged in the other end. An opening wall of the scope glass cup body is butted with one end of the screw plug. A photoelectric converter is embedded in the screw plug. A port at the other port of the screw plug is connected with a cable-to-cable connector. The high-temperature metal liquid temperature probe can effectively avoid smoke from scattering and absorbing optical radiation of radiation source, thereby furthest reflecting thermal radiation degree of radiation source and avoiding the defect of easy breakage and damage of long-distance optical cable under high-temperature environment at the same time. The high-temperature metal liquid temperature probe finishes sensitive measurement within 3s and has the characteristic of rapid and exact temperature measurement. In case of considering the demand of power input and a subsequent digital instrument, the high-temperature metal liquid temperature probe is provided with a secondary instrument for directly displaying and measuring data.
Description
Technical field
The utility model relates to a kind of high-temperature liquid metal body examination temperature sensor, belongs to instrument field.
Background technology
One of technology close with the utility model is to adopt contact method cavity thermometry to be used for the measurement of steelworks steel ladle temperature.This temperature-sensitive sensor adopts closed cavity, carries out the design philosophy of thermometric with contact method.It is to be provided with temperature sensing material in high-temperature ceramic, the method opto-electronic conversion that adopts temperature sensing material to be connected with optical fiber by optical system.During use sensor is fixedly mounted on the molten steel inclusion, high-temperature ceramic is fixedly extend in the molten steel, after long period thermal equilibrium, the radiation information of sensor senses cavity pipe integral body also is converted to temperature signal.This sensor has Measuring Time length and uses underaction shortcoming easily.If when being used to measure the blast furnace iron runner molten iron temperature, then the enclosed cavity pipe of this sensor must stretch into molten iron and just can measure significant data through behind certain heat balance time, if stretch into the life-span that also will have influence on components and parts in the cavity in the molten iron for a long time.
Two of the technology close with the utility model is, adopt the temperature in the method measuring radiation source of noncontact open cavity infrared measurement of temperature, this method is subject to the radiation source influence of flue dust on every side, measures temperature data and fluctuates very big, it is also bad to reproduce the repetition degree, and measuring accuracy is had a greatly reduced quality.
Summary of the invention:
The purpose of this utility model be to provide a kind of contact with thermal source and can be accurately, rapidly, be advantageously used in the measurement of flue dust environment, be convenient to the high-temperature liquid metal body examination temperature sensor of safeguarding, replacing.
Technical solution: the built-in endoscopy glass cup of steel cylinder overcoat one end of the present utility model, establishing screw thread in the other end is connected with screw is stifled, the stifled end of the perforated wall of endoscopy glass cup and screw connects, and screw is stifled to be embedded in photoelectric commutator, and its other end port is connected with cable-to-cable connector.
The outer shape of endoscopy glass cup is a truncated cone-shaped, and inside is cylindrical cavity.
The cup end of endoscopy glass cup, designed for plano-convex lens, and the focus of its convex lens is positioned on the photoelectric probe of photoelectric commutator.
Accompany asbestos pad between endoscopy glass cup and the steel cylinder overcoat.
The steel cylinder overcoat interior shape that is positioned at endoscopy glass cup place is a truncated cone-shaped, and it is cylindrical being positioned at the stifled place of screw steel cylinder overcoat interior shape, built-in herein screw thread.
The utility model is a kind of high-temperature metal liquid that is applicable to, especially can be in the flue dust environment accurately, the sensor of quick temperature measurement.
The utlity model has following characteristics:
1. be used for the temperature of flue dust environment measurement high-temperature metal liquid radiation source, simple to operate, thermometric is rapid, accurate, very little maintenance.The upper limit according to the high temperature resistant of endoscopy glass and anti-thermal shock characteristic selection decision thermometric.
2. be plano-convex lens at the bottom of being designed to glass of endoscopy glass body, the focus of convex lens is positioned at the photoelectric probe place of photoelectric commutator, and the plano-convex lens design of endoscopy glass body bottom more effectively focuses on the radiation of high-temperature metal liquid on the photoelectric commutator; The design of glass cup has also avoided the non-contact optoelectronic temp measuring method to be subject to the drawback of flue dust environmental impact; Photoelectric commutator is made up of photoelectric probe, opto-electronic conversion and radiating circuit and is sealed directly in the sensor, photoelectric probe closely is connected the damage that can avoid optical fiber with change-over circuit, increase the serviceable life of sensor, realize the long-distance transmissions of signal with radiating circuit; The design of the external truncated cone-shaped of endoscopy glass adds asbestos pad with steel cylinder overcoat inside and cooperates, makes its replacement, installation easier.

Embodiment
Establish endoscopy glass cup 1 in the utility model steel cylinder overcoat 3 one ends, establish screw stifled 4 in the other end, steel cylinder overcoat 3 interior shapes that are positioned at endoscopy glass cup 1 place are truncated cone-shaped, it is cylindrical being positioned at stifled 4 place's steel cylinder overcoat 3 interior shapes of screw, is provided with asbestos pad 2 between endoscopy glass cup 1 and the steel cylinder overcoat 3; Stifled 4 one ends of the perforated wall of endoscopy glass cup 1 and screw connect, and establish photoelectric commutator 5 in the screw stifled 4, and stifled 4 another port of screw are connected with cable-to-cable connector 6; The outer truncated cone-shaped that is shaped as of endoscopy glass cup 1, the cup end is a plano-convex lens, the focus of plano-convex lens is positioned on the photoelectric probe of photoelectric commutator 5.
During use, endoscopy glass cup 1 bottom of sensor is stretched in the high-temperature metal liquid, the optical radiation of high-temperature metal liquid enters in the endoscopy glass cup 1, endoscopy glass cup 1 bottom plano-convex lens focuses on optical radiation on the photoelectric probe in the photoelectric commutator 5, photoelectric commutator 5 adopts wireless transmission method, built-in rechargable power supplies, photoreceptor signal directly can be amplified, filtering imports simulating signal to digital circuit, signal passes through antenna on the cable-to-cable connector 6 through A/D conversion back by radiating circuit, and temperature detection signal is wirelessly transmitted to the far-end receiver the most at last.This sensor can charge at any time by cable-to-cable connector 6.This mode of operation of this sensor can be avoided scattering and the absorption of flue dust to the radiation source optical radiation effectively, reflects the heat radiation degree of radiation source to greatest extent, has also avoided long shortcoming apart from optical cable easy fracture damage in hot environment simultaneously.This sensor photosensitive is measured and can be finished in 3 seconds, has rapid, the accurate and easy-to-use characteristics of thermometric.
