【考案の詳細な説明】
この考案は、ロータリーキルン内のペレツ） ０）温度
測定装置に関する。[Detailed description of the invention] This invention relates to a pellet temperature measurement device in a rotary kiln.
第１図はロータリーキルンの全体構成を示した模式図で

空気Ｃを導入して、炉内を回転しながら緩やかに降下す
るペレットが順次還元、焼成される。Figure 1 is a schematic diagram showing the overall configuration of a rotary kiln. Pellets A are continuously charged into the rotary kiln 14 installed at an angle from the upper end, and fuel B and primary air C are introduced from the lower end. While rotating, the pellets descend slowly and are sequentially reduced and fired.

導入量が随時加減されるが、従来の温度コントロールは
温度計の測温値が不正確であるためかなり雑なものであ
った。In this case, it is necessary to raise the temperature of the pellets according to a predetermined pattern, and for this purpose, the amount of secondary air introduced from the fuel B1 or the shell burner 3 inserted in various places in the furnace is adjusted as needed. Conventional temperature control has been quite cumbersome due to inaccurate temperature readings from thermometers.

に邪魔され、測定が間接的になるばかりでなく、付層物
の多少によって測定精度に大きなバラツキを生じる欠点
があった。In other words, in order to directly measure the temperature of the pellets, conventional thermometers had the temperature-sensing part at the tip embedded in the brick lining of the kiln, but in reality, it was obstructed by the deposits that adhered to the key points of the kiln, making it difficult to measure the temperature of the pellets. Not only is this indirect, but the measurement accuracy also varies greatly depending on the amount of the layered material.

ペレット温度を検出するようにした点を特徴とする。The present invention aims to eliminate the above-mentioned drawbacks and provide a pellet temperature measuring device that can stably and accurately detect the heating temperature of the pedduct with a certain degree of precision. The temperature of the pellets inside the furnace is detected by passing a thermometer inside the shell burner and measuring the atmospheric temperature inside the furnace by protruding the temperature-sensing part at the tip of the thermometer to the outside from the tip of the burner. It is characterized by the following points.

れ示している。Figure 2 illustrates the results of experiments conducted by the inventors, including the actual temperature distribution of the pellet in the furnace (solid line), the measured temperature distribution of the atmosphere in the furnace (constant chain line), and the lining brick part (knee 111). The measured temperature distribution (dotted line) of the pellets is shown respectively.
炉内雰囲気の温度は本考案装置（後で詳しく説明する）
により測定した。The temperature of the furnace atmosphere is determined by the device of this invention (details will be explained later).
It was measured by

張りレンガに温度計を埋込んでペレットの温度を直接測

解される。As shown in this figure, not only is the ambient temperature closer to the actual temperature of the pellets, but the difference between the ambient temperature and the actual pellet temperature is always constant at each location in the furnace, so the temperature of the atmosphere in the furnace can be measured. It is understood that if appropriate corrections are made to this, the temperature can be detected more stably and accurately than by embedding a thermometer in the lining brick and directly measuring the temperature of the pellet.

It is firmly attached to the iron shell 1.

It is protected by a metal cover 11, and the joint with the burner 3 is fixed by welding or the like.
