TH type bucket elevator

The TH type bucket elevator has significant advantages such as large conveying capacity, high lifting degree, stable operation, and long service life. The traction adopts a circular chain, which is suitable for mining with good strength.

The TH type bucket elevator consists of a moving part (hopper and traction chain), an upper section with a transmission sprocket, a lower section with a tension wheel, a middle housing, a driving device, a reverse braking device, etc. The hopper of this elevator is arranged intermittently, using the "digging method" for loading and the "centrifugal feeding method" for unloading. The traction mechanism of this elevator consists of two circular chains.

The TH type bucket elevator is suitable for conveying powdery, granular, and small block shaped materials without grinding or with low grinding properties. TH type is a circular chain bucket elevator that uses mixed or gravity unloading and digging loading. The traction components have excellent quality and are made of high-quality alloy steel with a high circular ring chain. The central casing is divided into two forms: single channel and double channel. The internal heavy hammer box is automatically tensioned with constant force. The sprocket adopts a replaceable wheel rim combination structure. Long service life and easy wheel flange replacement. The lower part adopts a gravity automatic tensioning device, which can maintain a constant tension force, avoid slipping or chain detachment. At the same time, the hopper has a certain tolerance when encountering jamming caused by accidental factors, which can effectively protect the lower shaft and other components. This bucket elevator is suitable for conveying powdery, granular, and small block shaped bottom grinding materials with a bulk density of less than 1.5t/m3 that are easy to remove. Such as coal, cement, gravel, sand, fertilizers, grains, etc. TH type bucket elevator is used for vertical conveying of various bulk materials. Suitable for conveying powdery, granular, and small block materials, with material temperatures below 250 ℃.

Characteristics of TH type bucket elevator:

1. The TH type bucket elevator with the same bucket width has a large conveying capacity, and compared with the HL type bucket elevator, the conveying capacity is nearly doubled;

2. Adopting an assembled sprocket, the wheel body and rim are connected by high-strength bolts. After the sprocket is worn to a certain extent, the bolt can be unscrewed and the wheel rim can be replaced, which is convenient to replace and saves disassembly materials and reduces maintenance costs;

3. The lower part of the fuselage adopts a heavy hammer lever type tensioning device, which can achieve automatic tensioning. After installation, there is no need for adjustment and a constant tension can be maintained to protect the normal operation of the machine and avoid slipping or chain detachment;

4. The traction component is a low-alloy high-strength circular chain, which, after appropriate heat treatment, has high tensile strength and performance, and a long service life. This hoist is designed for mixed or gravity unloading, with a scoop type loading system. It is suitable for conveying low abrasive materials with a bulk density of no more than 1.5 tons/m3, including powder, granular, and small pieces. The temperature of the materials should not exceed 250 degrees Celsius.

There are two types of hoppers available:

ZH type (medium deep hopper) is generally used for conveying wet, agglomerated, and difficult to throw materials, such as wet sand, molding sand, fertilizers, alkali powder, etc.

SH type (deep hopper) is generally used for conveying dry, loose and easily thrown materials such as cement, crushed stone, coal blocks, etc.

There are two types of transmission devices for TH bucket elevator, which are equipped with ZJ type reducer and ZQ type reducer respectively. The ZJ type shaft mounted reducer is directly mounted on the main shaft head, eliminating the need for the elevator transmission platform, coupling, etc., making the TH type bucket elevator compact and lightweight. It also has a special-shaped roller backstop inside, which is excellent in backstop. The reducer has low noise, smooth operation, and floats with the main shaft, eliminating installation stress. The machine has a large conveying capacity of 365m3/h and a significant lifting height of 50m.
