Weighing pressure-tight belt coal feeder is used on the batching feeding of the power plant or coal feeding applications in other industries. The feeding process is a continuous belt feeding process. The feeder will feed the materials from the customer ’s feed hopper or other feed equipments and weigh the weight of the materials through the weighbridge. Meanwhile, the speed sensor in the tail roller measures the speed of the belt. The measured weight signals and speed signals are sent into the 6105P integrator together for the calculous calculation and the instantaneous flow rate in ton/hour unit and the totals in ton unit will be displayed. The inner adapter compares the measured instantaneous flow rate signal values with the preset flow rate values from the computer through the communication board, outputs the 3
relevant signal values based on the deviation, changes the rotate speed of the motor and make the feed rate same with the preset ones through the transducer and thus complete the control of the invariable feed rate. The total signals are sent into the computer for setting the stop function when the total reaches the standards. Conveyance and measurement are both carried out in the solid pressure tight body. There is a sweep-cleaning device, which can clean the spilled material and the fly ash to the coal discharger, in the lower part of the conveyance and measurement part.

Weighing pressure-tight belt coal feeder is used on the batching feeding of the power plant or coal feeding applications in other industries. The feeding process is a continuous belt feeding process. The feeder will feed the materials from the customer ’s feed hopper or other feed equipments and weigh the weight of the materials through the weighbridge. Meanwhile, the speed sensor in the tail roller measures the speed of the belt. The measured weight signals and speed signals are sent into the 6105P integrator together for the calculous calculation and the instantaneous flow rate in ton/hour unit and the totals in ton unit will be displayed. The inner adapter compares the measured instantaneous flow rate signal values with the preset flow rate values from the computer through the communication board, outputs the 3
relevant signal values based on the deviation, changes the rotate speed of the motor and make the feed rate same with the preset ones through the transducer and thus complete the control of the invariable feed rate. The total signals are sent into the computer for setting the stop function when the total reaches the standards. Conveyance and measurement are both carried out in the solid pressure tight body. There is a sweep-cleaning device, which can clean the spilled material and the fly ash to the coal discharger, in the lower part of the conveyance and measurement part. There are belt run-off alarm, coal blockage alarm, no coal alarm, chain breaking alarm and over-temperature alarm inside the body in the system. There are several monitoring windows, lights on the housing for the easy monitoring of the machines ’ operation. Structure introduction
