Dynamic material thermometer

Abstract

The invention discloses a dynamic material thermometer which can fully detect material temperature and improve material temperature detection precision. The dynamic material thermometer comprises a temperature sensor and a thermal conductor having a material charging end and a discharging end, wherein two material contacting planes are arranged between the material charging end and the discharging end and intersect with each other to form a material charging end. The included angle alpha between the two material contacting planes satisfies 0<alpha<180 degrees. The temperature sensor has a sensing terminal and a signal output terminal and is installed on the thermal conductor, and the sensing terminal of the temperature sensor extends into the thermal conductor. When the dynamic material thermometer is employed, the material temperature detection accuracy is improved, and great temperature detection error when material blocks appear can be prevented. The temperature sensor can detect the temperature of flowing material on a real-time basis.

Description

technical field [0001] The invention relates to a temperature detector, in particular to a dynamic material temperature detector. Background technique [0002] It is known that during the working process of the drying bed, it is necessary to detect the temperature of the material on the drying bed, and the material on the drying bed is in a flowing state, so real-time detection is required during the detection process. The traditional temperature detectors all use the temperature sensor of the cylindrical probe head, which is directly inserted into the flowing material for measurement. Since the temperature sensor of the cylindrical probe head is directly inserted into the material, the contact area between the cylindrical probe and the material is small At the same time, because the material is not fully scattered during the operation of the drying bed, there are material blocks in it, and there is a large temperature difference between the material fast and the scattered m...

The traditional temperature detectors all use the temperature sensor of the cylindrical probe head, which is directly inserted into the flowing material for measurement. Since the temperature sensor of the cylindrical probe head is directly inserted into the material, the contact area between the cylindrical probe and the material is small , at the same time, because the material is not fully scattered during the operation of the drying bed, there are material blocks in it, and there is a large temperature difference between the material fast and the scattered material temperature, and the temperature sensor with a circular probe cannot detect the average temperature of the material. Temperature, the detected temperature of the material has a large error and low accuracy, which affects the addition of auxiliary materials to the material in the subsequent steps, thereby reducing the quality of the final product
