A bucket elevator is a continuous conveying machinery that uses a series of hoppers uniformly attached to an endless traction component (such as a chain or tape) to transport bulk materials vertically or nearly vertically inward. The following is a detailed introduction about bucket elevators:

Ⅰ、 Structural composition

The bucket elevator is mainly composed of the following parts:

1. Hopper: Fixed on tape or traction chain, it is the main component for loading and transporting materials. According to the characteristics of the material, there are various types of hoppers, such as deep hoppers (suitable for loose materials), shallow hoppers (suitable for materials with high viscosity), triangular hoppers (suitable for materials with high specific gravity and block shape), etc.

2. Shell: equipped with transmission device and brake, protecting the internal structure of the hoist from external influences.

3. Body: Made of thin steel plates welded into a square shell, supporting the operation of the entire elevator.

4. Lower part: equipped with a tensioning device, used to maintain the stability of the chain or tape, reduce energy loss and vibration.

5. Drive device: including motor, reducer, coupling, etc., which can lift materials by driving the chain or tape.

Ⅱ、 Working principle

The working principle of a bucket elevator includes three steps: lifting, conveying, and unloading:

1. Lifting: When the driving device of the bucket elevator is started, the driving chain or tape starts to move from the wheel, and through the synergistic effect of gears and the operation of the chain plate, the material is lifted from the hopper to a high place.

2. Transmission: With the movement of the chain or tape, the material is stably transported to a high place and exposed at the discharge port through the synergistic effect of the chain.

3. Unloading: When the material reaches the target position, it is discharged from the hopper at a constant or faster speed through a guide nozzle or discharge door.

Ⅲ、 Characteristics

1. High conveying efficiency: The bucket elevator adopts a dense arrangement of large capacity hoppers, with a large conveying capacity and almost no material return or excavation during the lifting process, resulting in low ineffective power.

2. Wide range of improvement: With fewer requirements for the types and characteristics of materials, it can improve general powder, small particle materials, as well as materials with high grindability.

3. Stable operation: Reasonable structural design, smooth operation, high lifting height, good sealing, and minimal environmental pollution.

4. Long service life: The feeding adopts an inflow type, without the need for digging with a bucket, and there is little squeezing and collision between materials, reducing mechanical wear.

5. Low maintenance cost: The structure is simple, easy to maintain, and has good operational reliability, with a long fault free time.

Ⅳ、 Application Fields

Bucket elevators are widely used in multiple industries, such as:

1. Grain and feed processing industry: used for conveying raw materials, packaging and transportation of finished products.

2. Chemical and pharmaceutical industries: used for conveying powdered, granular, and small block materials.

3. Mining and metallurgical industry: used for conveying materials such as ore, slag, coke, etc.

4. Power and environmental protection industry: used for the transportation of materials such as coal, ash, desulfurization gypsum, etc.

5. Building materials and construction industry: used for conveying raw materials such as cement, sand and gravel, gypsum, etc.

In summary, bucket elevators play an important role in industrial production due to their efficient conveying capacity, wide applicability, and stable operating performance.
