In the
ultrafine mill production line, the protective device to be installed on the belt conveyor has the driving drum anti-skid protection, the coal protection, the anti-deviation device, the temperature protection, the smoke protection, the over-temperature automatic sprinkler and the centralized belt conveyor. Install a stop protection device along the line.
In addition, the belt conveyor installed in the main transportation lane should also prevent the person from contacting the driving roller or the guiding roller at the nose and the tail. The belt conveyor used in the inclined shaft must be equipped with an anti-reverse device when it is shipped, and a brake device must be installed when it is shipped.
Next, we will explain in detail the anti-running protection device. The function of the anti-running protection device is to automatically correct the conveyor belt when the conveyor belt is deflected; when the deviation is severe, the conveyor automatically stops. In the belt conveyor, a set of deviation protection sensors are installed on the nose and the tail. When the tape of the belt conveyor runs off, the tape pushes the arm type rolling guide. When the deviation angle is greater than 200mm (allowing error ± 30mm) When the switch is operated, the protector will open the alarm, but it will not cause a shutdown. After the 5-10s delay of the protector, if the tape is still in the deviation state, the protector will automatically cut off the power to achieve the deviation protection. . A set of anti-running wheels shall be installed at intervals of 30 to 50 meters in the middle part of the belt conveyor. The anti-deviation device shall be installed within 50-100 mm from the outer edge of the grooved idler to prevent the belt from running off.
The above contents first analyze the specific contents of the belt conveyor protection device in the
ultrafine mill production line, and the precautions for the installation of the protection device. Then explain in detail the anti-running protection device.
