Abstract
Description
technical field
[0001] The invention relates to the field of temperature measurement, in particular to a wireless temperature measurement and detection system on the surface of a cylinder body. Background technique
[0002] The paper machine dryer is the main equipment used to dry paper in the papermaking process. During the production process, the surface temperature of the drying cylinder is a very important process parameter. The temperature of the surface of the drying cylinder will affect the output of the paper machine and the moisture content of the paper. The drying cylinder is continuously transported around the axis, and the surface temperature is difficult to detect; at present, the contact temperature sensor is mainly used for measurement. This method is easy to cause scratches on the surface of the cylinder, damage the surface finish, and easily cause paper sticking; another method The steam temperature, pressure, condensate temperature, flow rate and other par...
Examples
Embodiment 1
[0026] Such as figure 1 Shown is a wireless temperature measurement and detection system on the surface of a cylinder body 9, including a cylinder body 9, a temperature sensor 1, a power module and a signal processing unit, and a heat insulation unit. The sensor 1 is placed in the installation hole 7, the heat insulation unit is arranged outside the cylinder body 9, the signal processing unit is connected to the temperature sensor 1, the power module and the signal processing unit are arranged outside the cylinder body 9 and separated from the cylinder body 9 by the heat insulation unit . In order to detect the temperature of the side wall of the cylinder body 9, a temperature sensor 1 needs to be installed, but there are high-temperature substances in the cylinder body 9 during operation, which causes the temperature of the cylinder body 9 itself to be high, exceeding the normal operating temperature of the electronic components, so only the temperature The sensor 1 is kept ...
Embodiment 2
[0035] Such as image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the installation hole 7 is parallel to the central axis of the cylinder body 9, a plurality of temperature sensors 1 are arranged in the installation hole 7, and the installation hole 7 is filled with a heat-conducting medium, and the temperature sensor 1 and the signal The processing unit is connected through a sealed cable, and the outlet of the installation hole 7 is sealed. Different from the previous solution, this method is easy to disassemble and maintain the temperature sensor 1. In addition, due to the difference in temperature at different parts of the cylinder body 9, the elongated installation hole 7 parallel to the central axis of the cylinder body 9 and the heat transfer medium can be used. The temperature detected by the temperature sensor 1 is more accurate, and at the same time, the heat transfer medium can prevent the change of the contact surface ...
