Determination or revision
This standard specifies the method for measuring the temperature of particulate materials. JBrT 9014.6-1999
J81C0668
This standard is applicable to the determination of the temperature of bulk materials in continuous conveying equipment, and is not applicable to the determination of the temperature of low-pressure materials. Referenced Standards
The following standards contain the following provisions: The provisions of this standard are constituted by reference in this standard. When this standard is published, all the relevant provisions are valid. All standards are subject to revision, so when the vehicle standard is used, the latest version of the following standards should be used. [B9014.1-1999 Specification for the performance of bulk materials in continuous conveying equipment and its classification FB, T9014.2-1999 Physical properties of bulk materials in reverse conveying equipment Test method 3 Key points of the method
Use thermometer to measure the channel temperature of bulk materials, 4 Instruments and tools
a) Armored thermocouple: stainless steel case protection, energy type. When the material temperature is below 600℃, use Jinnuo·Kajiu thermoelectric: When the material temperature is above 6℃, use platinum-zinc-platinum thermoelectric: b) Compensatory wire: platinum-cast thermocouple with steel-copper nickel compensation wire: chromium-ka copper thermocouple with steel-copper compensation wire, the length depends on the frequency requirement:
) Shared voltmeter: use portable type.
5 Test steps
5.1 Measure during slow feeding
Connect the compensation wire, test the meter, heat the package, stop the machine, and put the armored thermocouple into the observation porcelain of the conveying equipment before feeding! ! [or test hole] Place the thermocouple into the material flow of the conveying equipment, and start to observe the material oil pressure after 10m of cutting pressure in the heat exchanger, and record it. Measure it every 10m. A total of two times.
5.1 When measuring in the material flow being fed: Measure the feed temperature and the feed temperature, and measure the feed temperature in the material flow within [m] of the material flow: When measuring the calcium material temperature, measure it in the material flow within m before the material is placed. 5.3 In the process of measurement, the armored thermocouple pointed to by the user is strictly prohibited from touching the moving components of the conveying equipment to avoid accidents. In the production of six licensed conditions, you can do the measurement as much as possible,

.4 Scientific warehouse measurement
JH/T9014.6-1999
Insert the thermocouple into the silo according to the specifications of the silo (or hold it.), push it into the depth of 1-30cm, and connect the compensation line. After the thermocouple is inserted [0mir, measure the temperature drop and record it. Every 10 yuan is determined, for a total of 5.5 times. At least three measurements will be made at different heights, and four points at the same position will be measured. 6 Calculation of the temperature of the material at
by formula (1) (accurate to 1 Hz): rWww.bzxZ.net
is the average temperature of the material,
is the sum of the temperature of each set material,
is the number of temperature measurements at the point.
7 Result determination
Take the average of the three measurement results as the material temperature at that point, and take the maximum value of the temperature change at each point (generally the maximum material temperature) as the final value. When the temperature change at the site is large, the number of determinations, the location and the time should be determined quickly. The accuracy of the measurement should be clearly stated.
Test report
The requirements of 3.6 in BT4.2-1 are proposed in the test report.
