The invention relates to a stirring equipment temperature measurement structure including a hollow column jacket, a sealing cone pad, a temperature measuring head package, a chip type platinum resistor, a sealing gum, a heat insulation lengthened sleeve and a fastening head, the inner front end of the hollow column jacket is a conical surface, the middle part of the temperature measuring head package is provided with a blind hole, the outer surface of the temperature measuring head package is a cone structure, the chip type platinum resistor is installed in the blind hole of the temperature measuring head package by the sealing gum, the temperature measuring head package is mounted on the inner front end of the hollow column jacket, the temperature measuring head package and the inner end face of the hollow column jacket are sealed by the sealing cone pad, the heat insulation lengthened sleeve tightly abuts the temperature measuring head package, and the fastening head tightly presses the heat insulation lengthened sleeve and is connected with the column jacket. The stirring equipment temperature measurement structure not only can be installed for temperature measurement on a barrel wall, also can be installed as a temperature component for center temperature measurement in stirring equipment. The stirring equipment temperature measurement structure greatly reduces the cost of the barrel wall temperature measurement (reduces by 50%), much precisely controls of the stirring equipment temperature (+-1 DEG C), effectively guarantees the barrel vacuum, and is high in stability and convenient for assembly and disassembly.

Description

technical field [0001] The invention relates to a temperature measuring structure, in particular to a stirring device temperature measuring structure used in the stirring device. Background technique [0002] In the production of chemical industry, electronic slurry, coating, adhesive, cosmetics, grease, pharmaceutical, food and many other industries, the materials need to be mixed in the mixing equipment. Due to the high linear speed of stirring and dispersion, a lot of heat will be generated inside the material. , so it is necessary to carry out automatic temperature control (heating or cooling) on ​​the material being stirred to prevent the material from deteriorating due to too high or too low temperature. How to accurately detect the material temperature is particularly important. [0003] At present, the temperature measurement methods used by mixing equipment include plug-in temperature measurement, infrared temperature measurement, and traditional barrel wall tempera...

AI Technical Summary

Problems solved by technology

The temperature of the material needs to pass through the packaging board that is in direct contact with the material, and then be transmitted to the platinum resistor rod inside the package. However, because the platinum wires inside the rod-shaped platinum resistor are evenly distributed inside the platinum resistor, when the material temperature is transmitted to the platinum resistor, it is only transmitted to the platinum resistor. The local position of the front end of the resistance is similar to the plug-in temperature measurement, but because it only extends into the material at the end, the reaction to the material is slower and less accurate than the traditional plug-in temperature measurement.

Moreover, when the temperature is too high, when the circulating cooling water passes through the barrel wall, the detection effect of the platinum resistance will be affected, resulting in more inaccurate temperature detection. If the cooling water is to be isolated, the stirring tank will increase the production cost and cycle time.
