TD type bucket elevator

The TD type bucket elevator is suitable for vertically conveying powdery, granular, and small block shaped bulk materials with low grinding and suction properties, such as grain, coal, cement, crushed ore, etc., with a lifting height of 40m. Currently, the commonly used bucket elevators in China are vertical.

The characteristics of TD bucket elevator are: simple structure, smooth operation, digging type loading, centrifugal gravity unloading, and material temperature not exceeding 60 ℃; Compared with traditional D-type bucket elevators, TD series bucket elevators have better conveying efficiency and more hopper forms, so they should be preferred.

The TD bucket elevator is equipped with four types of hoppers, namely: Q-type (shallow hopper), H-type (arc bottom hopper), ZD type (medium deep hopper), and SD type (deep hopper). The TD series bucket elevators all use belts and hoppers to lift and transport materials, and have been widely used in industries such as grain, coal, fly ash, cement, crushed ore, quartz sand, and carbon.

The TD bucket elevator consists of a running part (hopper and traction belt), an upper section with a transmission drum, a lower section with a tension drum, a middle casing, a driving device, a reverse braking device, etc. It is suitable for conveying loose density ρ

The structural form of TD bucket elevator is: The transmission device of TD bucket elevator has two forms, each equipped with YZ type reducer ZQ (or YY) type reducer. The YZ type shaft reducer is directly installed on the main shaft head, eliminating the need for transmission platforms, couplings, etc., making the structure compact and lightweight. Moreover, it has a special-shaped roller backstop inside, which is excellent in backstop. The reducer has low noise, operates smoothly, and floats with the spindle, which can remove installation stress.

Characteristics of TD bucket elevator:

1. The driving power is small. Adopting inflow feeding, induction unloading, and a dense arrangement of large capacity hoppers, there is almost no material return or excavation during material lifting, resulting in less ineffective power;

2. The scope of improvement is wide. This type of hoist has fewer requirements for the types and characteristics of materials. It can not only lift general powder and small granular materials, but also materials with high grinding properties, good sealing, and less environmental pollution;

3. Running well. Excellent design principles and processing methods protect the excellent operation of the entire machine, with a fault free time exceeding 20000 hours. High lifting degree and smooth operation of the hoist, thus achieving a high lifting height;

4. Long service life. The feeding of the elevator adopts an inflow type, without the need for digging with a bucket, and there is little squeezing and collision between materials. Protecting materials from scattering during feeding and unloading during design reduces mechanical wear.

In addition, the elevator is equipped with a special-shaped roller backstop, which is excellent in backstop.
