Description

TECHNICAL FIELD

[0001] The utility model belongs to aluminum electrolysis cell temperature measurement technical field especially relates to a kind of fixing structure for aluminum electrolysis cell temperature measurement sensing device. BACKGROUND

[0002] Currently, the temperature sensor of the cathode steel rod temperature monitoring system of aluminum electrolysis cell applied in electrolytic aluminum industry generally adopts two types of magnetic attraction type and heat-conducting glue type, which has the following disadvantages:

[0003] Firstly, the magnet of the temperature sensor is in the electromagnetic field environment for a long time, and part of the magnetic force is offset, resulting in the temperature sensor falling off. This feature requires manual intervention for such sensors, which not only affects the real-time performance of temperature monitoring data transmission, but also fails to achieve the expected goal of replacing manual measurement with a temperature measurement system. Secondly, there is a gap between the magnetic attraction surface of the temperature sensor and the surface of the cathode steel rod, and the measured temperature deviates greatly from the actual temperature of the steel rod, affecting the judgment of the actual temperature of the steel rod by the monitoring personnel, and failing to achieve the expected goal of monitoring abnormal cells.

[0004] Although the heat-conducting glue type can ensure the accuracy of the collected temperature values for a short period of time, once the heat-conducting glue fails, the temperature test values will still be inaccurate, and it is more likely to cause the sensor to fall off compared to the magnetic attraction type.

[0007] Wherein, the diameter of the end of the conductive head is greater than the diameter of the sensor, and the conductive head is coaxially connected with the sensor.

[0008] Further, the bottom cover comprises a first part and a second part which are coaxially connected, the outer periphery of the first part is threadedly connected with the protective cover, and the end face of the second part abuts against the end face of the protective cover.

[0009] Further, the diameter of the first part is smaller than the diameter of the second part, and the diameter of the first part is smaller than the inner diameter of the protective cover.

[0010] Further, on the end face of the bottom cover, the projection of the elastic element is located at the outer periphery of the guide hole.
