AI Technical Summary

Technical Problem

The existing coal feeder coal breaking detection device is prone to failure in detection due to mechanical failure, and because the device is installed inside the coal feeder, it cannot be repaired online during operation, resulting in inconvenient maintenance.

Method used

The signal transmitting parts and signal receiving parts installed on both sides of the coal conveying belt in the coal feeder are used to replace the traditional coal-break detection baffle, and signal transmission is controlled through the coal-break detection processor, and the coal-break signal is automatically sent out in case of a fault.

Benefits of technology

It avoids detection failure caused by mechanical failure, realizes online maintenance, reduces the risk of shutdown due to maintenance, and improves the reliability and maintenance efficiency of equipment.

Abstract

The utility model discloses a coal feeder coal breaking detection device which comprises a signal transmitting component and a signal receiving component which are installed on the two sides of a coal conveying belt in a coal feeder respectively, the signal transmitting component faces the signal receiving component, and the installation height of the signal transmitting component and the installation height of the signal receiving component are both lower than the height of the top of a coal falling seam on the coal conveying belt. The signal transmitting part and the signal receiving part are both in communication connection with a coal interruption detection processor, and the coal interruption detection processor is used for controlling the signal transmitting part to transmit a detection signal and controlling the signal receiving part to receive the detection signal. And when the signal receiving part cannot receive the detection signal, the signal output device connected with the signal receiving part is controlled to send out a coal interruption signal. According to the coal breaking detection device for the coal feeder, detection failure caused by mechanical reasons can be avoided, online maintenance of maintainers is more convenient, and the production process cannot be affected by maintenance.
