AI Technical Summary

Technical Problem

The accuracy of temperature detection in existing reactors is relatively low, making it difficult to obtain a more accurate actual temperature in the reactor, mainly due to the interference of the sensor and the stirring blade, the inability to accurately contact the liquid material.

Method used

A temperature measuring device is designed, including a first hollow straight tube part, a hollow straight tube part and a second hollow straight tube part. Through the steering design of the hollow straight tube part, the interference of the stirring blade is avoided, so that the second hollow straight tube part can extend below the liquid level, so that the thermometer can obtain a more accurate material temperature.

Benefits of technology

In the reactor with stirring leaves, the temperature measuring device can accurately obtain the temperature of the material in the reactor, improve the accuracy of temperature detection, and avoid interference with the stirring structure.

Abstract

The utility model provides a temperature measuring device and a reaction kettle, and the temperature measuring device comprises a first hollow straight pipe part, a hollow bent pipe part, a second hollow straight pipe part, a thermometer, and a cable. The first hollow straight pipe part comprises a top end opening and a bottom end opening. The hollow bent pipe part comprises a top end opening and a bottom end opening, and the top end opening is hermetically spliced with the bottom end opening of the first hollow straight pipe part. The second hollow straight pipe part comprises a top end opening and a bottom end closing, and the top end opening is hermetically spliced with the bottom end opening of the hollow bent pipe part. And the thermometer is arranged at the bottommost part in the second hollow straight pipe part. One end of the cable is electrically connected with the thermometer, and the other end is led out from the top opening of the first hollow straight pipe part. The bottom of the temperature measuring device can be steered through the hollow bent pipe part, interference with a stirring structure in the reaction kettle is avoided, the bottom of the temperature measuring device extends to the position below the liquid level, and the thermometer can obtain the more accurate material temperature in the reaction kettle.
