There are some important points about how to increase the efficiency of the bucket elevator:
1, bucket elevator’s head is equipped with anti-kickback device. When the bucket elevator is working, the power suddenly interrupts; inverting bucket hoist is very dangerous. After the power interruption, bucket elevator due to gravity must produce reversal. The reversal is an acceleration movement, and then suddenly got stuck, easily ripped off the bucket, made the belt damaged, or even broken.
2, in the head and the bottom of the bucket elevator should have a suction tube and vent to ensure not format negative pressure and dust spills in the process of unloading and feed. However, a good seal in the material discharge and the feed process will inevitably produces a pressure difference, causing the feed and unloading difficult. The appropriate suction avoids dust overflow from the well-ventilated place, avoiding waste and cleaning up the environment.
3, set non-slip drive wheel, on the active wheel surface rivets or pastes non-slip, wear-resistant rubber cloth, can effectively improve the friction coefficient between the active wheel and capstan belt to prevent belt slippage and improve enhance efficiency. If the capstan table is too smooth, it need excessive tensioning belt to ensure the normal working of the hoist, the belt will be subjected to excessive tension and reduce the life of the belt.
4, install the speed monitoring device. In the passive wheel part of the bucket elevator installs speed sensor, the sensor produces a voltage or current signal, the maximum and minimum speed can be set through the instrument. When the speed of the bucket elevator exceeds this range, after a delay, if the speed is still out of range and it will alarm, and disconnect the air switch, effectively protect the normal work of the bucket elevator machine. Adopt good quality belt, some facts proved to buy good quality belt will not only improve productivity, but also can greatly reduce the accident rate of the bucket elevator.
