Screw conveyor

Availability:

The screw machine body is composed of head bearing, tail bearing, suspension bearing, screw, casing, cover plate and base. The driving device is composed of a motor, a reducer, a coupling and a base.

Screw conveyor is a kind of machinery that uses a motor to drive spiral rotation and push materials to achieve the purpose of conveying. It can be transported horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation.

Screw conveyors are divided into shaft screw conveyors and shaftless screw conveyors in the form of conveying. In appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors.Conveyor. The shaft screw conveyor is suitable for non-sticky dry powder materials and small particle materials. (For example: cement, fly ash, lime, grain, etc.)Shaftless screw conveyorSuitable for conveyors made of viscous and easy-winding materials. (For example: sludge, biomass, garbage, etc.)

The working principle of the screw conveyor is that the rotating spiral blade willmaterialsThe force of the screw conveyor to transport the material without rotating with the screw conveyor blade is the weight of the material and the friction resistance of the screw conveyor casing to the material. The spiral blade welded on the rotating shaft of the screw conveyor has solid surface, belt surface, blade surface and other types depending on the material being conveyed. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the axial reaction force of the screw with the material. When the length of the machine is long, an intermediate suspension bearing should be added.

Screw conveyor has the following characteristics:

1) The structure is relatively simple and the cost is low.

2) Reliable work, easy maintenance and management.
3) Compact size, small section size, and small floor space.
4) Sealed transportation can be realized, which is conducive to the transportation of flying, hot and strong odor materials, and can reduce environmental pollution.

5) Easy to load and unload. The horizontal screw conveyor can be loaded and unloaded at any point on the conveying line; the vertical screw conveyor can have excellent reclaiming performance relative to the screw reclaiming device.

6) It can convey in the reverse direction, and it can also make a conveyor convey materials in two directions at the same time, that is, towards the center or away from the center.


Structure:

1. The spiral blade of the screw conveyor has two directions of left-hand and right-hand.
2. The types of screw conveyors include horizontal fixed screw conveyor and vertical screw conveyor. The horizontal fixed screw conveyor is the most commonly used type. The vertical screw conveyor is used to lift materials in a short distance. The conveying height is generally no more than 8m. The spiral blade is a solid surface type. It must have a horizontal screw feeding to ensure the necessary feeding pressure.
3. The screw conveyor is composed of three parts: screw body, inlet and outlet and driving device. Screw conveyors are widely used in various sectors of the national economy, such as the grain industry, building materials industry, chemical industry, machinery manufacturing, and transportation. Screw conveyors are mainly used for conveying various powdery, granular and small block materials. The bulk materials conveyed include grains, beans, flour and other food products, cement, clay, sand and other building materials, salts and alkalis. , Chemical fertilizers and other chemicals, as well as bulk bulk cargoes such as coal, coke and ore. Screw conveyors are not suitable for conveying materials that are perishable, viscous, large in size, and easily agglomerated.
