Buried scraper conveyorBuried scraper conveyor is a transport equipment which makes the bulk material transpo...Bucket elevator, as one of the main equipment for vertical lifting of materials, is widely used because of its simple structure, smooth operation and large lifting capacity. It is mainly suitable for vertical lifting of powder, granular and small block materials and less abrasive bulk materials, such as grain, coal, cement, crushed ore, etc.In order to ensure production efficiency and specifications, bucket elevator operation considerations need to know.
Precautions for operation of bucket elevator:
1. Feed evenly.Sudden increase of feeding quantity is forbidden.The amount of feed shall not exceed the conveyor capacity of the elevator.Otherwise, it is easy to cause "boring car" accident when the material at the bottom accumulates seriously.
2. bucket elevator should start with empty load.Therefore, all materials in the hopper should be drained before each stop, and then stop.Strictly abide by the principle of "no load start, no load stop".
3. Before the bucket elevator is put into formal operation, carefully check the main parts of the head, tail and fuselage to ensure that all parts meet the requirements, and all stops and guard plates are in place and reliable;Check all start up, control and communication equipment to ensure its technical status is normal and good.
4. Test run. Empty car test can be conducted after installation.Empty operation should pay attention to: can not reverse, can not have bump phenomenon.No idle operation shall be less than 2 hours, and there shall be no overheating. The temperature rise of the bearing and reducer shall be within the specified range. After idle operation for 2 hours, the operation with load can be normally carried out.
5. often check the operating condition of the equipment, when the power is cut off, check whether the conveyor belt is cracked, dustpan is damaged, whether the belt joint is reliable, belt stretching, deviation, and other conditions.
6. Anti-reversal device is installed in the head of the bucket elevator.Reversing is very dangerous for bucket lifts when the power is suddenly interrupted in bucket lifts.
7. Air suction pipes and vents shall be provided at the head and bottom of the bucket elevator to ensure that negative pressure and dust spillage will not be formed during discharging and feeding of the bucket elevator.A well-made conveying equipment, its seal is reliable.
