A temperature online detection device

Abstract

The invention belongs to the technical field of heating temperature measurement and control in the firing process of sintered bodies, and specifically relates to an online temperature detection device, which includes a kiln car entering and leaving the kiln. The outer frame of the kiln car is provided with at least one fixing seat. Telescopic vertical rod, one end of the telescopic vertical rod is fixed on the fixed seat, the other end of the telescopic vertical rod is connected to one end of the telescopic horizontal rod, the other end of the telescopic horizontal rod is provided with a temperature detector installation hole, and a temperature detector is installed in the installation hole A temperature detector, an output of the temperature detector is connected to a controller, and an output end of the controller is connected to a display. The invention has a simple structure, can detect the actual temperature of the sintered body at different positions of the kiln car in real time, and greatly improves the qualified rate of finished products.

Description

technical field [0001] The invention belongs to the technical field of heating temperature measurement and control in the firing process of sintered bodies, and in particular relates to an online temperature detection device. Background technique [0002] In the process of firing ceramic billets in a kiln, the control of the sintering temperature directly affects the quality of the finished product. At present, a temperature detector is installed in the kiln to detect the temperature of the inner cavity of the kiln online in real time, and according to the detected temperature of the kiln The furnace cavity temperature controls the sintering heating temperature and heating time. This online detection system has the following problems: the detection temperature is the temperature of the kiln cavity, not the actual temperature of the sintered body. The error, especially the temperature error of the sintered body at the middle position of the kiln car is larger, and the actual ...

[0002] In the process of firing ceramic billets in a kiln, the control of the sintering temperature directly affects the quality of the finished product. At present, a temperature detector is installed in the kiln to detect the temperature of the inner cavity of the kiln online in real time, and according to the detected temperature of the kiln The furnace cavity temperature controls the sintering heating temperature and heating time. This online detection system has the following problems: the detection temperature is the temperature of the kiln cavity, not the actual temperature of the sintered body. The error, especially the temperature error of the sintered body at the middle position of the kiln car is larger, and the actual temperature change of the sintered body itself has a great influence on the performance of the later finished product. The existing online detection system cannot accurately measure the temperature of the sintered body during the firing process The actual temperature and temperature changes, especially the warm-up phase and cooling phase

If the temperature and time cannot be precisely controlled during the kiln firing process, it will affect the performance of the finished product, and even the finished product cannot reach the best performance index it should have achieved.
