Problems solved by technology

In order to ensure the accuracy of the electronic belt scale, it is necessary to regularly calibrate the electronic belt scale with weights, chain codes, counterweights, etc., and there is also a physical verification method that uses weighed materials to verify the accuracy of the electronic belt scale. In the above calibration and verification process, it is necessary to stop the relevant upstream and downstream equipment and take up a lot of time, which is difficult for enterprises with continuous production

Embodiment 1

[0027] Embodiment 1: Take a mineral processing plant in the south as an example, as figure 1 As shown, a method for accurately verifying an electronic belt scale is characterized in that it comprises the following steps:

[0028] (1) Determine the length of the check section

[0029] After the mineral material flows down from the hopper 1 to the electronic belt scale 4, and passes through the sensor 2 along with the belt, take a section of belt length L=15 meters after the sensor 2;

[0030] (2) Record data

[0031] The speed V=1.2 m / s and the weighing data A=278 tons / hour displayed by the electronic belt scale integrator 3;

[0032] (3) Sampling

[0033] After the data recording is completed, the belt conveyor is powered off, and the interlocked raw ore lower hopper is also powered off. The sampling personnel will take away all the materials on the belt surface with a determined length, and record the total weight M=850 kg; after confirming safety, the belt conveyor and T...

Embodiment 2

[0042] Embodiment 2: Take a mineral processing plant in the south as an example, as figure 1 As shown, a method for accurately verifying an electronic belt scale is characterized in that it comprises the following steps:

[0043] (1) Determine the length of the check section

[0044] After the mineral material flows down from the hopper 1 to the electronic belt scale 4, and passes through the sensor 2 along with the belt, take a section of belt length L=20 meters after the sensor 2;

[0045] (2) Record data

[0046] The speed V=1.3 m / s and the weighing data A=310 tons / hour displayed by the electronic belt scale integrator 3;

[0047] (3) Sampling

[0048] After the data recording is completed, the belt conveyor is powered off, and the interlocked raw ore lower hopper is also powered off. The sampling personnel will take away all the materials on the belt surface with a determined length, and record the total weight M=1260 kg; after confirming safety, the belt conveyor and ...

Description

technical field [0001] The invention relates to a physical object verification technology of an electronic belt scale, in particular to a method for determining the phase difference rate of material weighing. Background technique [0002] Electronic belt scales are used to collect weight data during material input and output, and are often used in benefit theory calculations, so they are widely used in various industries. In order to ensure the accuracy of the electronic belt scale, it is necessary to regularly calibrate the electronic belt scale with weights, chain codes, counterweights, etc., and there is also a physical verification method that uses weighed materials to verify the accuracy of the electronic belt scale. In the above calibration and verification process, it is necessary to stop the relevant upstream and downstream equipment and take up a lot of time, which is difficult for continuous production enterprises to implement. Contents of the invention [0003]...
