Bucket elevator

The bucket elevator chain bucket elevator is suitable for vertical conveying of powdery, granular and block materials, and can also lift materials with high abrasiveness. The material temperature generally does not exceed 200℃, and the maximum lifting height is 40 meters. Its main features are: It has a wide lifting range, large conveying capacity, low driving power, inflow feeding, gravity-induced unloading, long service life, good sealing performance, stable and reliable operation, convenient operation and maintenance, compact structure, good rigidity and low operating cost.

Advantages and features

It has a large conveying capacity, with a lifting volume ranging from 50m ³ /h to 500m ³ /h.

2. Wide lifting range: This bucket elevator has few requirements for the type and characteristics of materials. It can be used for powdery, granular and fast materials.

3. The driving power is small. It adopts inflow feeding and induced discharge, and the large-capacity hoppers are densely arranged. When lifting materials, there is almost no backflow or digging of materials, so the ineffective power is low.

4. High lifting height: It adopts plate chain type and high-strength chain, and the lifting height can reach 60 meters under the rated conveying capacity.

5. The upper and lower wheels are assembled sprockets, and the flange is connected to the wheel body with high-strength bolts. When the sprocket wears out, only the flange needs to be replaced. This not only makes the replacement convenient but also saves materials and reduces maintenance costs.

6. The bucket elevator has good structural rigidity and high precision. The casing is folded and embossed in the middle. After welding, it has good rigidity and a beautiful appearance. It has a low comprehensive cost, good sealing performance, is energy-saving and environmentally friendly, and requires little maintenance.

7. The whole machine occupies a small area, which is conducive to the layout of the equipment. As it is vertical conveying, it only takes up the area of the casing.

8. It has excellent sealing performance and is environmentally friendly and pollution-free.

9. It operates smoothly and has stable performance. This equipment has no precision components and adopts inflow feeding and induced discharge. Its overall structure is simple and economical and practical.

Working principle

The bucket elevator is composed of the upper section, the middle casing, the lower section, the traction components such as the conveyor belt with buckets, the transmission device and the outdoor maintenance platform.

The lower section is composed of the feed inlet, the lower casing, the redirecting wheel set and the tensioning device.

2. Middle casing (for maintenance), one section per unit, used for installing and maintaining traction components.

3. Middle casing (anti-deviation), usually one is placed every five sections of the middle casing.

4. Connecting plates are usually placed in the middle of the casing every two sections.

5. Middle casing (standard), L=2 meters.

6. Connecting frames are usually placed in the middle of the casing every five sections.

7. Middle casing (non-standard), with L ranging from 0.5 to 2 meters. It is generally installed at the middle casing of the first or second section in the upper section.

8. The upper section, including the upper casing and the drive roller assembly.

9. Drive unit. It is composed of a motor, a vertical shaft reducer, a hydraulic coupling, a backstop device and a slow-motion device.

10. Outdoor operation platform.

11. Traction device. The casing of the hoist adopts a fully sealed design to prevent environmental pollution or material spillage, which could lead to waste. The hoppers are densely arranged on the traction belt or chain. They receive materials at the feeding port in the lower section and are fed in a flow-through manner. The conveyor belt or chain lift is vertically lifted to the top, passes around the top wheel and then flips downward. By taking advantage of the centrifugal force of the materials and the designed Angle of the hoppers, the materials are quickly thrown out. Gravity-induced unloading is adopted. The materials enter the discharge port. Then the hopper continues to descend, scooping up the small amount of material that was scattered inside the casing during material collection, and continues to collect materials, repeating this process.
