1 Main features of bucket elevator
1. The driving power is small, and inflow feeding, induction unloading, and large capacity hoppers are densely arranged. There is almost no material return or excavation during material lifting, resulting in less ineffective power.
2. The range of improvement is wide, and this type of improvement machine has fewer requirements for the variety and characteristics of materials. It can not only improve the usual powder and small particle materials, but also improve materials with high grinding properties. It has good sealing and less environmental pollution.
3. Good operational reliability, advanced planning principles and processing methods ensure the reliability of the entire machine operation, with a defect free time exceeding 20000 hours. Raise the height. Improve the smooth operation of the machine, thus achieving a higher elevation.
4. With a long service life, the feeding of the machine adopts an inflow type, without the need for digging with a bucket, and there are few occurrences of kneading and bumping between materials. This machine ensures that materials are rarely scattered during feeding and unloading during planning, reducing mechanical wear and tear.
2 Working principle of bucket elevator
The conveying operation principle of the bucket elevator is that the hopper scoops up the material from the storage below, and as the conveyor belt or chain lifts it to the top, it flips down after passing around the top wheel. The bucket elevator tilts the material into the receiving groove. The transmission belt of the bucket elevator with belt drive is usually made of rubber belt, which is installed on the upper or lower transmission drum and the upper and lower reversing drums. A bucket elevator with chain drive is usually equipped with two parallel drive chains, with a pair of drive sprockets on top or bottom and a pair of reversing sprockets on top or bottom. Bucket elevators are usually equipped with a casing to prevent dust from flying in the bucket elevator.
The safe and accurate use of bucket elevators can prevent problems during operation, and regular protection and maintenance can ensure the normal use of bucket elevators. Here are a few points to note:
1. The bucket elevator should be driven with no load. So before each shutdown, all materials in the hopper should be drained before parking.
2. Cannot be reversed. Reversing may lead to the occurrence of chain derailment, and cleaning up the derailment problem is very troublesome.
3. Feed evenly. Stop the sudden increase in feeding volume. The feeding amount cannot exceed the conveying capacity of the elevator. Otherwise, if the material accumulation at the bottom becomes severe, a "stuck car" incident may occur.
4. Timely and appropriately replenish lubricating oil.
5. When the chain and hopper are severely worn or damaged, they should be replaced in a timely manner
