Fully intelligent and high-precision bucket wheel conveyor belt scale

        -------Dynamic weighing technology "Pearl on the Crown"

　Yike Electric's "fully intelligent high-precision bucket wheel conveyor belt scale" can accurately weigh the bucket wheel stacker and reclaimer belt conveyor while it is moving, the rack is pitching, rotating left and right, and the inclination angle changes. It is maintenance free during use and can maintain weighing accuracy of ≤ 0.4% for a long time

system composition

The high-precision matrix scale mainly consists of four parts: n sets of B159A5 matrix weighing bridge, E897W imported speed sensor, imported MT8X digital converter, imported MW900X matrix scale specialized matrix intelligent instrument (with 8-16 separate AD sets), three-dimensional dynamic weight compensator ET1170, and temperature compensator PY50. The weighing sensors in the matrix bridge detect the weight of materials on the belt, and each group of matrix scales has a separate AD that is fed into a digital converter; The converter converts the analog quantity of the sensor into digital quantity and sends it to the integrator; The speed sensor directly measures the real-time speed of the conveyor belt, eliminating errors caused by monitoring the speed of the return belt or the speed of the active drum in the past, and sending the actual real speed information into the matrix intelligent instrument; The proprietary weight compensator ET1170, which places standard weight weights on an independent specialized matrix scale body, provides real-time actual weight signals when the angle of the bucket wheel crane arm changes and sends them to the intelligent instrument for weight compensation; The temperature compensator PY50 provides real-time environmental temperature signals to be sent to the instrument for temperature compensation of the entire system. The instrument processes the received speed and weight signals, and processes them through a proprietary matrix weighing and integrating intelligent data model to obtain the cumulative quantity and instantaneous flow rate of the material. The weighing sensor itself has special functions of temperature compensation and linear compensation, which improves the stability of the bucket wheel scale in case of leakage. Equipped with a weight compensator, designed specifically for stackers and reclaimers, it is far superior to angle compensators from other manufacturers and is an essential innovative tool for bucket wheel scales.

Core features of high-precision bidirectional metering matrix scale for bucket wheel stacker reclaimer
The variable angle matrix scale is a mobile belt scale developed on the basis of the matrix belt scale, which is installed on variable angle equipment such as stackers and reclaimers or mobile docks. The mobile belt scale adopts the "three-dimensional motion tracking compensation technology" and has a weighing accuracy of better than 0.2% in any inclination angle and direction from -18 ° to+18 °, and maintains a weighing accuracy of better than 0.4% in long-term use.

High precision attitude tracking system

High precision tracking and detection of three-dimensional posture changes in the weighing unit during movement, and compensation and correction of the impact of posture changes on weighing, ensuring accurate weighing of the belt scale in various motion states.

Sensor precise compensation technology

It can overcome the impact of temperature changes in the outdoor environment of the sensor and the impact of sensor zero point imbalance output. Independent temperature compensation is used to compensate for the environmental temperature variables of the entire conveyor, ensuring high accuracy even when temperatures cannot be reached.

Overcoming the influence of belt tension

The influence of belt tension is basically eliminated, and there is no requirement for symmetrical rollers, and there is no accumulation of empty belts.

Bidirectional calibration system

The operation of the conveyor in both stacking and reclaiming directions is essentially two different conveyors. The world of variable angle matrix scales has unique bidirectional calibration, fully integrating in two weighing environments in both stacking and retrieval directions, just like two scales running.

Low flow compensation system

Large flow fluctuation is the working feature of the bucket wheel stacker reclaimer at the ore terminal. Different ore densities vary greatly, and the bucket wheel itself changes in real time during the moving reclaiming process, which results in the actual situation that the flow of the same ore varies from high to low, and different ores work at different rated flows. In the production control of ore terminals, there is a practical need for stable and accurate measurement under various working conditions. To ensure accuracy in complex working conditions, especially during low flow operation, the variable angle matrix scale intelligent instrument implements low flow data verification and automatic compensation technology. In low flow operation, the sampling frequency of high-precision weighing sensors is increased and intelligent compensation is achieved, achieving high accuracy in low flow operation. The matrix scale itself is particularly suitable for measuring bulk materials with large fluctuations in flow rate.
