Stainless steel shaftless screw conveyor

Stainless steel shaftless screw conveyorIt mainly consists of a power unit, head assembly, casing, shaftless spiral body, wear-resistant lining plate, feed inlet, discharge outlet, hood (if needed), base, etc.

1. WLS shaftless screw conveyor drive device: using cycloidal pinwheel reducer or shaft mounted hard tooth surface gear reducer, the drive device should be designed to be located at the discharge port end as much as possible, so that the screw body is in a tensile state during operation.

2. The head of the WLS shaftless screw conveyor is equipped with thrust bearings, which can withstand the axial force generated when conveying materials.

3. WLS shaftless screw conveyor housing: The housing is U-shaped, with an upper cover (if needed), made of stainless steel, carbon steel, or fiberglass.

4. WLS shaftless screw conveyor shaftless screw body: made of stainless steel or wear-resistant steel.

5. WLS shaftless screw conveyor wear-resistant lining plate: wear-resistant non-metallic material.

6. WLS shaftless screw conveyor inlet and outlet: There are two types: square and circular. If the user has no requirements, the square type will be supplied.

The shaftless screw conveyor has strong resistance to entanglement: due to the absence of central axis interference, it has special characteristics for conveying belt shaped, viscous materials, and easily entangled materials. For example, it is used for conveying fine grids in sewage treatment plants, with a net distance of 50mm between the grid bars for cleaning machine slag and filter press mud cake, or for handling and transporting garbage in garbage disposal sites, which can prevent accidents caused by blockage.

Stainless steel shaftless screw conveyorThe shaftless screw conveyor is different from the shaft screw conveyor, as the requirements for the screw blades are not very high for the shaft screw conveyor. Because the intermediate shaft of a shaft screw conveyor can help prevent the deformation of the spiral plate, while a shaftless screw conveyor has good requirements for the spiral plate because it does not have an intermediate shaft. Generally, the spiral plate of a shaftless screw conveyor is required to be at least 6 millimeters to avoid the strong pressure caused by material accumulation and deformation of the spiral plate.

Shaftless screw conveyors are widely used in various industries, such as building materials, chemicals, electricity, grain, etc. They are suitable for horizontal or inclined transportation of powdery, granular, and small block materials, such as coal mines, ash, slag, cement, grain, etc., with material temperatures below 200 ℃. Spiral machines are not suitable for conveying materials that are prone to deterioration, high viscosity, and clumping. The role of the screw conveyor is demonstrated in the concrete mixing plant. Convey powdery, granular, and small materials with low viscosity, low spoilage, and no clumping Spiral conveyors have the advantages of simple structure, low manufacturing cost, strong sealing, and easy operation. They can be loaded and unloaded at multiple points in the middle
