Principle of Material superposition self-calibration technology

Guide:

SANON Three Bridge Material superposition self-calibration technology is to install two groups of weighing scale racks on the belt conveyor, and two groups of buffering idler groups are installed between the two weighing scale racks, and a weighing hopper is installed above the two groups.

The scraper reclaimer installed on the belt conveyer conveys the material in the belt conveyor, according to the timing of the weighing instrument set timing, the material is conveyed by screw conveyor into the weighing hopper.

When calibrating, the weighing hopper opens and discharges. At this time, the first group of belt scale racks weighed the weight of the transported material, and the second group of belt scale racks weighed the weight of the transported material and the weight of the standard weighed down hopper, based on the first group of belt weighers and the second group of belts. The amount of material conveyed by the scale frame (excluding the material of the weighing hopper) is the same. The weighing instrument subtracts the weight of the first set of belt scale frames from the weight of the second set of belt scale frames to obtain the weight hopper. The standard material weight value, the standard material weight value and the weighing instrument's own displayed material weight value are compared to obtain the correction coefficient, and the correction instrument is calibrated according to the correction coefficient to display the standard material weight value.

Regularly comparison and correction are the characteristic that the belt measurement accuracy reaches high stability and accuracy. At this time, the full length of the belt conveyor stores materials, the calibration conditions are close to the normal conveying conditions, the accuracy of the calibration belt scale is the most accurate, so that low cost and less material calibration replace the multi-material calibration.

The main features are as follows:

1. It adopts self-developed small-scale self-calibration technology that superimposes weighing materials and normal conveying materials to solve the problem that the current belt scales have high physical calibration costs and are difficult to calibrate.
2. The real-time online material self-calibration technology can automatically perform material self-calibration when the belt conveyor normally conveys the material, which effectively guarantees the accuracy and durability of the long-term operation of the belt.
3. The two belt scales are compared in real time and are used as backups. When one of the belt scales fails, the system automatically alarms it and uses another belt scale as the main weighing scale to continue operation, improving the reliability of the system.
