The invention relates to a deep hole temperature measurement device. The deep hole temperature measurement device comprises a protection cover, an electrically-conductive slide ring, a signal wire encapsulation pipe, a temperature sensor and a sensor pressure applying mechanism. The temperature sensor is installed on the bottom end of a blade axial pore and attached to the wall of the blade axial pore through the compression of the sensor pressure applying mechanism. A conducting wire of the temperature sensor is connected to the electrically-conductive slide ring through the signal wire encapsulation pipe and connected with a control device through the electrically-conductive slide ring. The protection cover is fixed on the upper end surface of a connection ring in the electrically-conductive slide ring. By adopting the deep hole temperature measurement device, the temperature of a material inside a fast rotation device can be measured in real time, a temperature signal is outputted to an external display and control system, so that the rotation speed of the machine can be controlled in real time, and the accident caused by overhigh temperature can be prevented.
Description
technical field [0001] The invention relates to temperature measurement in the production of energetic materials, in particular to a deep hole temperature measurement device. Background technique [0002] In the production process of energetic materials, temperature control is very important. Every process step requires strict temperature measurement, otherwise it may cause safety accidents. However, in some high-speed operating equipment, the internal friction of the material under the agitation of the blades will cause local heating, and at this time the real-time temperature of the material is not easy to measure. At present, the temperature measurement for this occasion mainly adopts two methods of intermittent temperature measurement and temperature measurement by opening holes on the wall of the mixing pot. Intermittent temperature measurement needs to stop stirring first to measure temperature. This method cannot reflect the temperature of the material in real time a...
