Tube Screw Conveyor

Tube screw conveyor is also called tubular screw conveyor, which can convey powder or granular materials horizontally, inclined and vertically. It is a continuous conveying equipment that uses spiral rotation to move materials. Different types of conveyors or feeders can be used for concrete production (fly ash, filler dust, silica fume), premixed building materials (dry plaster, sand, cement , additives), glass processing (calcium carbonate, soda, sand, etc.), foundries (sand, bentonite), etc.

The screw diameter of the tubular screw conveyor is 100-1250mm, the speed is fast, the material is not jammed, the material is not arched, and the material is discharged smoothly. Because the conveying process is carried out in a closed pipeline, there is basically no dust pollution, and the conveyed material will not leak. Improved work environment.

Types of Tube Screw Conveyor

There are various types of tube screw conveyors available, each designed to meet specific application requirements. Here are some common types:

1.Horizontal Tube Screw Conveyor: This is the most basic type of tube screw conveyor, where the tube is horizontal, and the screw rotates to move material along the length of the conveyor. It is suitable for horizontal conveying of bulk materials over short to medium distances.

2.Inclined Tube Screw Conveyor: In this type, the tube is inclined at an angle, allowing for vertical or inclined conveying of materials. Inclined tube screw conveyors are used when there is a need to transport materials between different levels or when a specific elevation angle is required.

3.Vertical Tube Screw Conveyor: Also known as an elevator conveyor, a vertical tube screw conveyor is used for lifting bulk materials vertically. It is commonly used for applications where materials need to be elevated to a higher level, such as transferring materials to silos or storage bins.

How does a tube screw conveyor work?

Material Intake: The material to be transported is fed into the inlet of the tube screw conveyor.

Rotation of the Screw: The helical screw blade, also known as an auger, rotates inside the tube. This rotation creates a pushing or pulling action, depending on the design, which moves the material along the length of the tube.

Material Transport: As the screw rotates, it carries the material along the tube. The design of the screw blade helps in effectively moving different types of materials, such as powders, granules, or small pellets.

Discharge: The material reaches the discharge end of the conveyor, where it can be directed to the next stage of the process, a storage container, or another destination.

Advantages of Tube Screw Conveyor

1. Closed design: The tubular design minimizes dust emissions and protects materials from contamination and external factors.

2. Versatility: Suitable for transporting a variety of materials, including bulk powders, grains and granules, suitable for horizontal, inclined or vertical conveying, and can meet the conveying needs in different industrial scenarios.

3. High space utilization: The compact design can save space and is suitable for factories or production lines with limited space.

4. Flexibility: The tubular design can adapt to different conveying angles and paths, providing flexibility and diversity, and can be customized according to needs.

Customization

Tube screw conveyors can be customized according to different application requirements and material characteristics to meet specific conveying requirements.

1. Cooling type: It is used to quickly cool high-temperature materials. It adopts a unique water cooling system. By setting a jacket on the outside of the barrel or the screw shaft and the conveying pipeline, cooling water circulates in the jacket. The cooling water absorbs the heat generated by the material during the conveying process, which reduces the material temperature. It not only realizes the material conveying, but also effectively reduces the material temperature.

2. Stirring type: The screw conveyor combined with the stirring function is equipped with a stirring device (feeder) at the feed inlet, which is used to crush the damp and agglomerated products before conveying. It is commonly used in food processing and chemical production.

3. Anti-corrosion type: It is made of corrosion-resistant plastic material (polypropylene), which can resist chemical corrosion and is suitable for conveying corrosive materials.

Structure of Tube Screw Conveyor

Tube screw conveyor generally consists of three parts: conveyor body, inlet and outlet and drive device. The spiral body is composed of three parts: the head section, the middle section and the tail section.

Driving device: Q series reducer + Y series motor, YTC gear reducer motor.

Feeding and discharging device: There are four kinds of feeding port, square discharging port, hand-push discharging port and rack-type discharging port. It is welded on the body by the user at the site of use. When arranging the positions of the inlet and outlet ports, attention should be paid to ensure the distance from the material port to the end, and at the same time, avoid the material port from colliding with the hanging bearing refueling cup, the casing connection flange, the base, etc.

Screw machine body: A thrust bearing is installed in the head section to bear the axial force, and a bearing is installed in the middle section and the tail section to support the screw shaft. At the same time, there are axially movable radial bearings in the tail section of the screw conveyor to compensate for the error of the length of the screw shaft and adapt to temperature changes.
