Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.
Referring to fig. 1-3, a position-finding type temperature thermocouple 1 comprises a temperature thermocouple 1, a protective cap 2, a screw 3, a liquid level plate 4, a lead and an instrument control unit 7, wherein the protective cap 2 is sleeved outside a temperature measuring end of the temperature thermocouple 1, and the tail part of the protective cap 2 is connected with the temperature thermocouple 1; the protective cap 2 is of a straight-tube hollow structure, and a liquid panel 4 is embedded in the protective cap 2; the lead and the liquid level plate 4 are connected with the instrument control unit 7 to form a closed circuit.
Wherein, the protective cap 2 is fixedly connected with the temperature thermocouple 1 through the screw 3, which can conveniently limit the distance between the liquid panel 4 and the temperature thermocouple 1. The protective cap 2 is made of refractory materials and protects the temperature thermocouple 1. A liquid panel 4 is embedded in the protective cap 2 close to the head. The liquid surface plate 4 is a metal thin plate or a metal wire. The instrument control unit is used for detecting, processing and outputting liquid level and temperature measurement signals.
The instrument control unit 7 comprises a liquid level recorder, a temperature recorder and a data processing and output module. The liquid level recorder is connected with the liquid level plate in a closed circuit mode through a first lead 5, the temperature recorder is connected with the temperature thermocouple 1 through a second lead 6, and the data processing and output module is responsible for processing output signals of the liquid level recorder and the temperature recorder and sending the output signals to the management control center.
When the temperature thermocouple 1 contacts the molten metal liquid surface, the liquid surface plate 4 is firstly melted, the instrument control unit 7 detects that the closed circuit is changed into an open circuit and the temperature abrupt change pulse signal is output outwards, so that the liquid surface is detected, and then the position-measuring type temperature thermocouple 1 is quickly inserted to the set depth to ensure the temperature measuring precision.
