Description
Technical Field
The utility model provides a temperature measuring device for detecting a plurality of point temperatures in an oven. In particular, the temperature measuring device can accurately detect the temperature of a plurality of points in the oven and synchronously reflect the temperature change of each point in the oven in real time.
Background
The hot drawing is a key flow in the processing process of the ultra-high molecular weight polyethylene fiber. Currently, in industry, the common hot stretching is carried out in a drawing oven with an internal air guide system. The temperature inside the drawing oven determines to a large extent the effect of the hot drawing of the fibres and the final quality of the product. In order to control the temperature at each point in the draw oven, the temperature profile inside the oven needs to be tested first. However, the oven internal temperature exceeds 100 ℃, which is not suitable for contact measurement with a manual thermometer. Meanwhile, the volume of the oven is large, the testing density is high, and the efficiency is very low by adopting a point-by-point testing method. In addition, the temperature measuring device cannot be accurately installed on a temperature measuring point due to the limited inner space of the oven. These factors severely limit the performance of draw oven temperature measurements.
At present, the temperature measurement mode used by the oven is mostly detected by adopting the mode of fixing the positions and the number of the temperature sensors, and the positions and the number of the collection points in the oven can not be flexibly adjusted. Generally, 1 to 5 temperature measurement control points are configured for one oven in consideration of cost reduction and convenience in writing control programs. The number of temperature measuring points cannot be flexibly adjusted. The fixed temperature measuring point is generally positioned in the middle of the oven, about 80% of the width of the oven is required in production, when the heat distribution and the temperature distribution of the oven have problems, the deviation reflected on the fixed temperature measuring point is small, and the actual quality condition of the product has deviation and even exceeds the quality control range.
Therefore, there is a great need for a synchronous, multiplexed temperature measuring device that can be used in a draw oven for fiber processing enterprises and oven manufacturers.
