Interior temperature measuring equipment for material bed of belt-type sinterer

Abstract

The invention relates to the field of iron ore sintering equipment, in particular to interior temperature measuring equipment for a material bed of a belt-type sinterer. The interior temperature measuring equipment for the material bed of the belt-type sinterer comprises a fire-resistant tube, a thermocouple set, a protective sleeve and a dataline joint. The protective sleeve is fixedly connected with the fire-resistant tube. The dataline joint is installed in the fire-resistant tube. The thermocouple set is installed in the protective sleeve and is formed by arranging a plurality of thermocouples. The tops of the thermocouples are connected with the dataline joint. The bottoms of the thermocouples are stair-stepping. A slice for shielding an electrical insulating fiber body is arranged between two adjacent thermocouples. The gap in the fire-resistant tube is filled by high temperature resistant asbestos, and the gap in the protective sleeve is filled by high temperature resistant insulating particles. According to the interior temperature measuring equipment for the material bed of the belt-type sinterer provided by the invention, the temperature instantaneous values at different positions in the height direction in the sintering material bed can be tested with rapid response speed and small temperature measuring error. The interior temperature measuring equipment for the material bed of the belt-type sinterer can work in a comparatively severe environment in the production process. A bump is arranged on the fire-resistant tube, so that the measuring precision is further improved.

Description

technical field [0001] The invention relates to the field of iron ore sintering equipment, in particular to a temperature measuring device inside a sintering machine material layer. Background technique [0002] During the iron ore sintering production process, the internal temperature distribution of the material layer on the belt sintering machine trolley has an important influence on the sintering process. The temperature distribution of the material layer will affect the shape, thickness and moving speed of the sinter zone, combustion zone, dry preheat zone, wet zone and cold material zone formed by the sintering material. In sintering production practice, whether the internal temperature distribution of the material layer is uniform or not will affect the uniformity and stability of the quality of the sintered cake in the width direction of the trolley, and will also affect whether the edge effect near the side wall of the trolley can be controlled, thereby affecting th...

Problems solved by technology

According to the comprehensive analysis, the first method needs to modify the equipment, and will cause damage to the trolley, so it is not suitable for frequent testing

However, the cost of using infrared temperature measuring devices is relatively high, and more expenses need to be added. The accuracy and maintenance of infrared temperature measuring devices are greatly affected by environmental factors.
