Spiral Vertical Elevator
Spiral vertical elevator consists of running part (hopper and traction belt), upper section with driving drum, lower section with tensioning drum, intermediate casing, driving device, backstop braking device, etc. It is suitable for upward conveying loose density ρ<1.5t/m3 powder, granular and small lumps of non-abrasive and semi-abrasive bulk materials, such as coal, sand, coke, cement, crushed ores, etc. The TD type bucket elevator structure form: transmission device TD type bucket elevator transmission device has two forms respectively with YZ type reducer ZQ (or YY) type reducer. TD type bucket elevator structure form: transmission device TD type bucket elevator transmission device has two forms were equipped with YZ-type reducer ZQ (or YY) type reducer. YZ-type shaft reducer is directly mounted on the spindle head, eliminating the need for transmission platforms, couplings, etc., so that the structure of the compact, lightweight, and its internal with a special type of rollers with a backstop, backstop reliable. The reducer has low noise, smooth operation, and floats with the spindle, which can eliminate the installation stress.
Spiral vertical elevator, is a large mechanical equipment for transportation by changing potential energy, such as mine elevator, over dam hoist, etc. Broadly speaking, elevators, overhead cranes, winches, stable cars, cranes, starters, etc. can be called hoist. Elevator generally refers to the larger power, lifting capacity of large mechanical equipment.
Spiral elevator, is a large mechanical equipment for transportation by changing potential energy. Such as mine hoist, over the dam hoist. Broadly speaking, elevators, overhead cranes, winches, stable cars, cranes, starters, etc. can be called hoist. Elevator generally refers to larger power, lifting capacity of large mechanical equipment. Used to vertically lift through the crusher of limestone, such as block granular materials, as well as raw materials, cement, coal powder and other powdered materials. According to the hopper running speed is different, bucket elevator can be divided into: and other three forms. Centrifugal unloading bucket speed is faster, suitable for conveying powder, granular, small pieces of small abrasive materials; gravity unloading bucket speed is slower, suitable for conveying lumpy, specific gravity, abrasive materials, such as limestone, clinker and so on. Bucket elevator traction components are ring chain, plate chain and tape and so on. The structure and manufacture of ring chain is relatively simple, and the connection with the hopper is also very firm, when conveying abrasive materials, the wear and tear of the chain is small, but its self-weight is large. The structure of plate chain is more solid, the weight is lighter, it is suitable for elevator with large lifting capacity, but the articulated joints are easy to be worn out, the structure of adhesive tape is relatively simple, but it is not suitable for conveying materials with large abrasiveness, the material temperature of ordinary adhesive tape is not more than 60°C, the temperature of the material allowed to be clamped with steel rope adhesive tape is up to 80°C, the material temperature allowed to be heat-resistant adhesive tape is up to 120°C, and the temperature of the material conveyed by ring chain and plate chain is up to 250°C.
Spiral elevator is mainly used for conveying powdery, granular and small lumpy materials, chemicals, etc. Spiral elevator is not suitable for conveying easily deteriorated, viscous and easily caked materials.
The rotating spiral blade will push the material to be conveyed, so that the material does not rotate with the spiral elevator blade is the material's own weight and the friction resistance of the spiral elevator casing on the material. Spiral elevator rotating shaft welded spiral blade, blade face type according to the different materials conveyed entity face type, belt face type, blade face type and other types. Spiral elevator spiral shaft in the direction of material movement at the end of the thrust bearing, in the spiral tube is longer, should be added in the middle of the hanging bearing.
