Main Components Of Bucket Elevator

Nov 07, 2024 Leave a message

The bucket elevator consists of a hopper, a driving device, top and bottom rollers (or sprockets), adhesive tape (or traction chain), a tensioning device, and a casing.
Traction components
(1) Rubber strap:
Fix the tape with screws and elastic washers at the tape mouth, with a width of 35-40mm wider than the bucket. Generally, the tape can transport materials with a temperature not exceeding 60 ℃, while heat-resistant tape can transport materials up to 150 ℃.
(2) Chain:
The single chain strip is fixed on the back wall of the hopper; The double chain is connected to both sides of the hopper. When the hopper width of the chain hoist is 160-250mm, a single chain is used, and when the hopper width is 320-630mm, a double chain is used. The main disadvantage is that the wear between the chain links is large, which increases the frequency of maintenance.
(3) Chain wheel:
The transmission sprocket on the bucket elevator. Chain wheels are used to mesh with accurately spaced blocks on chain links or cables, and are solid or spoke gears that mesh with roller chains to transmit motion.
The design of the tooth profile of the sprocket: The tooth profile of the sprocket must ensure that the chain can enter and exit meshing smoothly and freely, minimize the impact and contact stress of the chain links during meshing, and be easy to process. The sprocket material should ensure that the teeth have sufficient strength and wear resistance, so the sprocket tooth surface is generally heat-treated to achieve a certain hardness.
Hopper
(1) Cylindrical bucket:
The deep bucket and bucket mouth are inclined, with a large depth, used for conveying granular materials that are dry, have good fluidity, and can be easily scattered.
(2) Shallow hopper:
The mouth is inclined and has a small depth, used for moist and flowing granular materials.
(3) Deep hopper:
Deep bucket materials are generally dry and have good flowability.
(4) Triangle hopper:
The material is generally discharged in a directional self flow manner.
(5) Sharp edged bucket:
Its side wall extends to the outside of the bottom plate, becoming a blocking edge. When unloading, the material can be discharged along the groove formed by the blocking edge of a bucket and the bottom plate, which is suitable for transporting viscous and heavy block materials.
