Temperature measuring system

Abstract

The invention discloses a temperature measuring system which comprises a guide rail, a temperature-measuring device and at least one heat-conductive element. The temperature-measuring device is arranged on the guide rail, and the guide rail is parallel to the central axis of a rotary kiln to be measured. The rotary kiln to be measured comprises at least one temperature-measuring hole, each heat-conductive element is inserted into one temperature-measuring hole, the temperature-measuring hole is formed from the shell of the rotary kiln to be measured to the furnace lining direction, and a preset thickness is reserved to enable the furnace lining not to be penetrated. The temperature-measuring device moves on the guide rail, and is used for obtaining the temperature of the part, arranged at one end of the kiln shell, of the heat conductive element. The temperature measuring system can detect the temperature of the heat conductive element in real time, and can further automatically judge the operating situation of the rotary kiln according to the temperature data, no staff needs to take part in the detection process, and the timeliness of the temperature detection and accuracy of judgment of the operating situation are improved. In addition, the temperature detected by the temperature measuring system is closer to the real temperature inside the kiln than the kiln shell temperature measured in the prior art.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a temperature measurement system. Background technique [0002] Rotary kiln is a continuously rotating cylindrical high-temperature kiln placed obliquely, which is used for drying, roasting and calcination of materials. In the production process involving the rotary kiln, the calcination of materials is often an extremely important process in the process. According to the specific process environment and requirements, the temperature and control requirements of the rotary kiln are also different. If it is not accurate If the temperature in the kiln is detected, it may not be possible to effectively control the fuel supply and air volume supply of the rotary kiln, resulting in uneven control of the temperature in the kiln along the axial direction of the rotary kiln, and the phenomenon of knotted kiln or red kiln. [0003] During the long-term production process of the rotary k...

Problems solved by technology

When necessary, the inspectors take the initiative to detect the surface temperature of the kiln shell through a portable thermometer. This method of actively measuring the temperature by the inspectors makes the timeliness of temperature detection poor, and there may be delays in detection that may result in the detection of The temperature judgment of the operating status of the rotary kiln lags behind, and then the phenomenon of red kiln appears; in addition, after the heat in the kiln is transferred to the kiln shell through the furnace lining, the temperature detected at the kiln shell is quite different from the real temperature in the kiln, which cannot reliably reflect the kiln temperature. inner real temperature
