Description

Technical Field

[0001] The utility model relates to the technical field of detection alarm equipment, in particular to a weighing deviation type coal feeder belt deviation alarm system. Background Art

[0002] A coal feeder is a piece of mechanical equipment that is mainly used to transport coal from one place to another, usually from a coal storage yard or coal storage warehouse to a boiler or other combustion equipment. It is widely used in power plants and other industrial facilities to ensure a smooth supply of fuel. Nowadays, coal feeders usually use a belt deviation alarm device when working, so that it can detect whether the belt is deviating in time, avoid equipment failure or safety accidents caused by deviation, and protect the safety of equipment and personnel.

[0003] A Chinese patent with announcement number CN116062399A discloses a coal feeder belt deviation alarm device. When the belt on the roller deviates during the process of conveying coal, the belt moves left / right and pushes the weight to swing left and right. At the same time, the weight pulls the shaft rod to swing left and right with the shaft core of the sealed shaft wheel as the base point, so that the end of the shaft rod located outside the coal feeder cylinder contacts the button on the button-type alarm. In addition, the control end of the button-type alarm is connected to the DCS control system. The logic is designed as a parallel loop. When any signal is connected, an alarm is triggered and the coal feeder is stopped after a delay of minutes. However, it is difficult to quickly reset the pendulum after the shaft rod presses the button-type alarm through the swing of the weight. As a result, the pendulum will continuously impact the belt through inertia, increase the wear of the device, and damage the button components, shorten the life of the alarm device and increase maintenance costs. At the same time, the continuous impact of the pendulum may make the operation of the alarm device unstable, making it difficult to accurately detect and reflect the actual belt deviation situation, affecting the accuracy and reliability of the device.
