4、 Working principle

The belt coal feeder will detect the weight of the materials passing through the belt through multiple sets of B150A2 matrix weighing sensors under the weighing scale frame to determine the weight of the materials on the belt; A digital speed sensor installed on the outer end drum of the bearing continuously measures the coal feeding speed, and the pulse output of the speed sensor is proportional to the belt speed; The speed signal and weight signal are sent together to the belt feeder controller to generate and display cumulative/instantaneous flow rate. The coal feeding controller compares the flow rate with the set flow rate, and the controller outputs a signal to control the frequency converter speed regulation, achieving the requirement of quantitative coal feeding.

5、 Main features

◆ All output points are sealed with multi-layer side packing to meet the pressure requirements of the equipment
◆ Sealing the air interface, adopting a multi-point air outlet structure to improve the sealing effect and effectively isolate hot air
◆ The surface of the externally mounted active drum of the bearing is adhered with a herringbone shaped rubber plate, which has a self-cleaning function to prevent the tape from deviating
◆ The external driven drum of the bearing adopts a waist drum type and self-cleaning structure, with automatic centering function to prevent deviation and coal sticking
◆ Flat roller structure, circular skirt edge flame retardant tape, effectively preventing material scattering, skirt edge height of 40mm
◆ The diameter of the flat roller is 89mm, and the steel surface is cylindrical. The radial runout relative to the roller shaft is small, which is conducive to measurement
◆ There are two belt cleaning devices installed on the inner and outer sides of the measuring and conveying belt of the coal feeder, ensuring the accuracy of weighing and the stability of the zero point
◆ The bottom of the coal feeder adopts a chain scraper conveyor to clean the fly ash
◆ The coal feeder shell is equipped with multiple observation windows, convenient swing arm type access doors at both ends, and multiple lighting lights on the body
◆ Integrated high-precision matrix scale patented automatic calibration device, no need for manual operation, self checking and self calibration
◆ The main and driven rollers of the tape and the cleaning chain are both equipped with external bearings, achieving long-term maintenance free operation of the coal feeder
◆ The speed sensor is installed on the external driven drum shaft end, which not only obtains accurate speed but also is not affected by coal powder interference
◆ The broken chain alarm is installed at the end of the external cleaning chain driven wheel shaft, which can accurately detect the broken chain without being disturbed by coal falling.

6、 Matrix weighing unit
The high-precision weighing coal feeder adopts the patented B150 matrix scale frame (patent number: ZL 2018 2 0620230.1) from Eko, and the B150A2 series matrix belt scale has a dynamic cumulative error less than± 0.2%, which is specially used for metering of coal feeder and proportioning scale, coal feeding metering of power plant sulfuration bed boiler, sintering proportioning metering of iron and steel plant, proportioning metering of various chemical plants, trade metering and other metering in the feeding process with high accuracy and stability requirements, providing reliable guarantee for Lean manufacturing, energy conservation, efficiency improvement and quality improvement of enterprises.

Adopting multiple sets of matrix weighing units, the structure is simple and does not require maintenance. The scale frame unit structure has no material accumulation, so there will be no zero drift and the system has good stability. Using intelligent algorithms to maintain a long-term accuracy of 0.25%.

7、 Integrated automatic verification
Adopting advanced integrated automatic verification methods and mastering core patented technology (ZL 2018 2 0591107.1), the verification accuracy and convenience have been improved to unprecedented heights.
Equipped with a unique matrix automatic calibration system, automatic calibration can be achieved by pressing a button, making the calibration of the coal feeder easy and efficient.
The matrix weighing controller automatically judges the accuracy of the system, and once there is a deviation, it will automatically control the calibration device to achieve online correction.
ECO can provide high-precision matrix weighing technology upgrade and transformation services for all coal feeder users, completely solving the long-term problem of inaccurate coal feeders for users.

8、 External installation of key components such as bearings, speed measurement, tension, etc
The front and rear belt rollers and cleaning chain bearings of the coal feeder are both externally installed, using the plate groove multi loop sealing method developed by ECO, which is reliable in pressure resistance. The belt conveyor and lower cleaning chain both use external spiral tensioning devices, which have sufficient travel. The speed sensor and chain breakage monitoring are both external, completely eliminating the intrusion of pressurized coal powder and greatly improving the service life. In addition to regularly adding grease to the bearings through external oil injection holes, there is no need for other maintenance.
 

　

9、 Guide ™ Patent automatic alignment device (Patent No. of the China: ZL201820589546.9)
Due to unstable tension, roller movement, roller sticking, and uneven material warehouse pressure, the coal feeder may experience belt deviation. In order to ensure that the weighing section of the belt scale is not affected by the deviation of the belt, IKE World is the first to install an intelligent power generation self guiding device outside the weighing area of each high-precision coal feeder or on the return belt to ensure the good operation of the conveyor, balance and adjust the deviation of the belt during the operation. The passive power generation automatic guiding device is equipped with a specially developed high-efficiency Microgeneration device to convert the kinetic energy of the belt deviation into electrical energy, By using intelligent inverter technology to convert electrical energy into high-strength thrust, the operation path of the conveyor belt is guided, achieving fully automatic and efficient deviation free guidance, completely eliminating deviation, strengthening the stable operation of the belt conveyor for metering and ensuring the worry free operation of the coal feeder.
