Wear resistant thermocouple for internal mixer is a temperature control element used to measure the rubber temperature in the confidential rubber mixing chamber, and belongs to a temperature sensor in the temperature automatic control device.The utility model is composed of a wear-resistant head, a thermocouple shell and a thermocouple wire. The wear-resistant head is fixed at the front end of the thermocouple shell, and the thermocouple wire is welded at the top of the wear-resistant head. The two poles of the wear-resistant head are insulated. The wear-resistant head is filled with a high thermal conductivity material whose thermal conductivity is higher than that of the thermocouple shell, and is sealed with a sealing ring.AnHui TianKang(Group)Shares Co.,Ltd thermocouple can reduce the measurement temperature lag and improve the measurement sensitivity and service life.

The wear-resistant thermocouple for internal mixer is mainly used for accurate measurement of rubber in internal mixer.The wear-resistant thermocouple for internal mixer is composed of wear-resistant head, thermocouple shell and thermocouple wire, which is characterized in that the wear-resistant head is fixed on the front end of the thermocouple shell, the thermocouple wire is welded on the top of the wear-resistant head, its two poles are insulated, the wear-resistant head is filled with high thermal conductivity material with a thermal conductivity higher than the thermocouple shell, and is sealed with a sealing ring.Wear resistant thermocouples for internal mixer purpose wear resistant thermocouples for internal mixer are mainly used for accurate measurement of rubber in internal mixer.The main features of wear-resistant thermocouple for internal mixer are that the tip part is made of ultra-high strength alloy for aviation industry, with yield strength δ 0.2 ＞ 1100mpa (206mpa for 1Cr18Ni9Ti), tensile strength δ B ＞ 1300mpa (520mpa for 1Cr18Ni9Ti),It does not deform under the ultra-high pressure in the internal mixing room. The sensitivity of special patent design is not lower than that of the same kind of imported products. The wear-resistant department adopts thickening treatment, and the continuous working life is not lower than 4000H. In actual use, there are many records of more than 9000h. The junction box adopts the imitation imported junction box, which is fixed by double bolts, so as to avoid the box cover falling off and entering the rubber material, causing quality accidents.Technical parameters of wear-resistant thermocouple for internal mixer ● operating temperature: 0-250 ℃ ● graduation number: J (k) ● thermal response time: ＜ 1.0s ● accuracy: ± 1.5 ℃

Type and performance of wear-resistant thermocouple protection tube for internal mixer

The tip part of Wear-resistant thermocouple for internal mixer is made of industrial ultra-high strength alloy, which has high yield strength and tensile strength, and does not deform under ultra-high pressure in internal mixer. The sensitivity of special patent design is not lower than that of imported products of the same kind. The wear-resistant part is thickened, and the continuous work is not less than 4000 hours. There are many records of more than 9000 hours in actual use,The high-temperature wear-resistant head is an integral blind hole processing of wear-resistant alloy independently developed by our company. It performs well in the power plant circulating fluidized bed boiler, fluidized bed furnace and rotary kiln tail of cement plant where there are high-temperature particles strongly scoured. Long time high temperature (normal operation temperature > 1000 ℃),Under the condition of strong corrosion (high sulfur atmosphere) and high-speed solid particle erosion (8mm diameter, speed > 5m / s), the service life is more than 1 year.
