Description
The present invention relates to a fire detection apparatus for a belt conveyor that is installed in a thermal power plant and the like to detect the fire generated during the operation of the belt conveyor for transporting and supplying raw coal, and the rotation of the carrier roller to assist the drive of the belt conveyor. The present invention relates to a fire detection device for a belt conveyor that reduces the installation cost by simplifying the configuration of the fire detection device while enabling accurate fire detection and fire prevention by measuring speed and ambient temperature in real time.
In general, a belt conveyor is a device that loads or stores raw coal stored in a yard to a target device or facility. The belt conveyor determines the driving unit, head chute, and transfer section connected to the reducer and the head pulley by power from the drive motor. It consists of a part, a tail chute and a tensioning device that keeps the tension of the belt conveyor constant, and a belt and a carrier roller.
Such a belt conveyor fires when heat generated by continuous friction between the tail pulley and the frame stand, or the carrier roller and the belt due to accumulation of coal falling from the top of the rock protection plate installed in the tail portion or the backside of the belt. Became a ignition factor, and caused a meandering state of the belt,
At this time, the fire occurs frequently due to friction between the carrier roller and the belt, the production equipment is damaged, the mass production is lowered, and in the case of a large belt conveyor, it is difficult to detect the fire occurrence area.
Accordingly, Patent Registration No. 10-0644531 (name of the invention: a belt conveyor equipped with a fire detection device) enables the early detection of a fire that may occur in the belt conveyor with an optical sensor cable so that the user can be notified and the raw coal There is a belt conveyor provided with a fire detection device that is generated from the back and is attached to the optical sensor cable to clean the dust to always be able to detect high sensitivity.
However, in the case of the belt conveyor equipped with the fire detection device, as shown in Figure 1, the
Due to the complicated configuration, there is a difficulty in manufacturing the device and mounting the belt conveyor, and it takes a lot of time and money for maintenance.
If the optical sensor cable is disconnected or broken due to external impact or long time use, there is a problem in that it is insufficient to detect a fire because a replaceable fire detection means is not provided.
The present invention has been made to solve the above problems, it is possible to accurately measure the temperature around the carrier roller, and at the same time simplify the configuration of the belt conveyor fire detection device to reduce the manufacturing cost of the device, belt conveyor installed over a long distance In order to provide an economic belt conveyor fire detection device by reducing the installation cost for the auxiliary equipment required when installing the temperature measuring sensor unit on each of the carrier roller and the roller stand provided in a large number along the
In addition, even if a failure occurs due to external shock or long time of use, the temperature measuring sensor unit is equipped with a separate means for detecting fire by improving the accuracy and soundness of fire detection. Make it possible to provide a sensing device.
In order to solve the above problems, in one embodiment of the present invention, a plurality of belts are provided at predetermined intervals along the belt, and are rotatably coupled on a rotating shaft and a

The fire detection apparatus of the belt conveyor according to the present invention, when the temperature measuring sensor unit and the rotational speed sensor unit are installed on each of the carrier roller and the roller stand provided with a large number along the belt conveyor installed over a long distance, each of said temperature measuring sensor After connecting the part and the rotational speed sensor unit to each section group, it is configured to determine the fire by receiving the measurement signal for each group, so that the temperature around the carrier roller and the rotational speed of the carrier roller can be accurately measured. At the same time, it is possible to simplify the configuration of the fire detection apparatus, thereby lowering the manufacturing cost of the apparatus, and reducing the installation cost for the auxiliary equipment required.
In addition, by combining the rotational speed measuring sensor unit for measuring the rotational speed of the carrier roller with the temperature measuring sensor unit, it is possible to detect a fire caused by friction between the carrier roller and the belt in advance, and the temperature measuring sensor unit external impact However, even in the event of a failure due to the use of a long time, it is possible to detect the occurrence of a fire in advance, thereby improving the accuracy and soundness of the fire detection.
