Flexiblespiral archemedes screw pipe tube conveyor is bulk material handling equipment, which usually consists of a tube containing either a spiral blade coiled around a shaft (sometimes called an auger), driven at one end and held at the other. The main parts include tube, shaft with spiral blades, inlet and outlet chutes, as well as driving device.
The closed pipe-type screw conveyor is a pipe with a shaft inside with welded screw blades and passive bearing. The screw's blades have different pitch which depends on the type of the transported raw material and the planned capacity. This type of conveyor is closed, which means that the screw cannot be accessed directly. Due to the closed structure, the transported raw material does not spill outside the machine during transport.
The machine can be equipped with a pull screw. In this version, the drive unit is located in the direction of the raw material feeding. Some screw conveyors are equipped with push screws with gear motor installed on the feeding side. The screw conveyor is fitted with an initial or end bearing. Depending on the type of transported raw material, slide or bearing rests are installed.
Horizontal screw conveyor has the advantages of sealed operation, simple structure. screw conveyor suitable for conveying powdery, granular and small bulk materials horizontally or aslope, such as coal, ash, slag, cement, food, etc. screw conveyor is an new transportation equipment.
Simple structure, good sealing, large capacity, long service life
Convenient installation and maintenance, as well as easy operation.
Working temperature is -20~50ºC, with material temperature below 200 ºC.
Suitable for horizontal and slightly inclined transport of powdery, granular and small lump materials, such as coal, ash, clinker, cement, grain, etc.
Widely used in construction, chemical, power, metallurgy, coal and grain industries, etc.
Industrial pipe auger spiral flexible screw elevator/conveyor for sugar, flour, coffee, powder is widely used in chemical, metallurgy, paper making, and construction industries. The equipment is mainly suitable for field flowing work, such as concrete mixing station, bulk material transit storage, etc.
AdvantagePerformance and Features:
It can be sealed to prevent the escape of dust or fumes from inside the conveyor; or prevent dust contamination from outside the conveyor.
It can be used to control the flow of material in processing operations which depend upon accurate batching
It can be utilized in the horizontal, vertical or any inclined position depending upon the characteristics of the product being conveyed.
It can be used as a mixer or agitator to blend dry or fluid ingredients, provide crystallization or coagulant action, or maintain solutions in suspension.
Screw conveyors can have multiple conveyor outlets, making discharge to multiple outlets cost effective.
It can be jacketed to serve as a drier or cooler by running hot or cold water through the jacket.
It can be made out of a variety of materials to resist corrosion, abrasion or heat, depending upon the product being conveyed.
It can be outfitted with multiple inlet and discharge points.
The screw conveyor consists of power device, gear box, coupling, screw axis and hanging bearing. The screw axis is made of several sections which connected with spline. Hence, the conveyor hold large load capacity and convenient to dismounting. It is open a besel on the casing to ensure a safe operation.
The material moves along the spiral within the tube. The unique action of the flexible spiral conveyor eliminates the risk of the product separation that can take place in conventional pneumatic conveying systems where mixed materials have components of different densities and particle size.
Information Needed For The Quotation
Primary considerations for the selection of a screw conveyor are as follow:
Type and condition of the materials to be handled, including maximum particle size, and, if available, the specific bulk density of the material to be conveyed.
Quantity of transported material, expressed in pounds or tons per hour.
The distance for which the material is to be conveyed.
Below is the necessary information for the selection of a screw conveyor system, presented in a series of five steps. These steps are arranged in logical order, and are divided into separate sections for simplicity.The five steps are:
Establishing the characteristics of the material to be conveyed.
Locating conveyor capacity (conveyor size and speed) on capacity tables.
Selection of conveyor components.
Calculation of required horsepower.
Checking of components torque capacities (including selection of shaft types and sizes)
Routine periodic inspection of the entire conveyor must be established to ensure continuous maximum operating performance. Keep the area around the conveyor and its drive clean and free of obstacles to provide easy access and avoid functional interference of components.
Power Lock Out:
Lock out power to the motor before attempting any maintenance. Use a padlock and tag on the drive's controls. Do not remove padlock or tag, nor operate conveyor, until all covers and guards are securely in place.
Removing Screw Sections:
Screw sections are typically removed starting with the end opposite the drive when necessary. Remove trough end, screw sections, coupling shafts, and hangers until damaged or worn section is removed. Reassemble conveyor in reverse order.
Periodically remove and inspect one of the drive shaft coupling bolts for damage or wear. Also inspect the coupling bolt hole. The drive shaft coupling bolts transmit more power than successive coupling bolts and will typically indicate the greatest wear. An accurate torque wrench should always be used when tightening coupling bolts. Excessive torque will stretch the bolt and significantly compromise its strength.
Lubricate end bearings, hanger bearings and drive components at the frequency and quantity specified by the individual component's manufacturer. Most types of hanger bearings require lubrication and wear is reduced significantly with a frequent lubrication schedule. Frequency of schedule depends on temperature, type of bearings, type of lubrication, product conveyed, trough load, screw weight, etc.)
Screw Bushings/Internal Collars:
The bushing at each end of a screw will wear over time. When possible, check for excessive shaft movement that indicates bushings need to be replaced. Longer and heavier screws typically have greater bushing wear.
