AI Technical Summary

Technical Problem

In existing temperature measurement systems, the temperature measuring tube cannot be fixed, causing heat from the graphitization furnace to leak out along the gap between the mounting hole and the temperature measuring tube. Furthermore, gaps exist in multi-segment combined temperature measuring tubes, affecting the accuracy of temperature measurement.

Method used

The support brick is connected to the temperature measuring tube body through a fixed part and a supporting part to form an arc-shaped fixation, reducing gaps. An inert gas purging air path and a cooling jacket are set to reduce heat loss and flue gas entry, thereby improving the accuracy of temperature measurement.

Benefits of technology

This achieves a secure connection between the temperature measuring tube and the external wall, reducing heat loss, ensuring the accuracy and safety of temperature measurement data, and avoiding high-temperature flue gas pollution.

Abstract

This utility model belongs to the field of graphitization furnace temperature measurement technology, specifically relating to a negative electrode graphitization furnace core temperature measurement system, including a temperature measuring tube and a thermometer. The temperature measuring end of the temperature measuring tube passes through the outer wall of the graphitization furnace and is close to the furnace core. An optical path channel is provided along the length of the temperature measuring tube, and the thermometer measures the furnace core temperature using this optical path channel. The temperature measuring tube is connected to the outer wall by a supporting brick. The supporting brick includes a fixing part and a supporting part located below the fixing part. The fixing part and the supporting part together fasten the temperature measuring tube, and the fixing part and the supporting part are respectively fixedly connected to the outer wall. This utility model uses a supporting brick to fix the temperature measuring tube, making the temperature measuring tube and the outer wall integrated, resulting in a more secure installation of the temperature measuring tube.
