The screw conveyor is mainly composed of a driving device, a head assembly, a casing, a shaft screw, a tank liner, an inlet, an outlet, a cover, a base, etc.
Driving device: Cycloidal pin wheel reducer or shaft-mounted hard-toothed gear reducer is used. When installing, the driving device should be installed at the end of the discharge port as much as possible, so that the spiral body is in a tensioned state during operation. The head is equipped with a thrust bearing, which can withstand the axial force generated when conveying materials.
Chassis: The casing is U-shaped or O-shaped, with a rainproof cover on the top, made of stainless steel, carbon steel or glass fiber reinforced plastic.
Shaft spiral body: the material is stainless steel or carbon steel.
Tank liner: the material is wear-resistant plastic plate or rubber plate or cast stone plate, etc.
Inlet and outlet: There are two types of square and round. Generally, the form of inlet and outlet is determined by the user.
The difference between a shaftless screw conveyor and a shaft screw conveyor mainly depends on the working conditions of the materials you convey. The main difference lies in whether there is a central shaft design, and each has its own characteristics and advantages.
There are three differences
1. The shape and structure of the shaftless screw conveyor: drive, shell, lining plate, shaftless blade, cover plate, etc.; the composition of the shafted screw conveyor: drive, shell, inner tube shaft, blade, cover plate, etc.
2. The situation of conveying materials The shaftless screw conveyor is suitable for conveying materials: sludge, domestic garbage, grid slag, etc. are sticky, entangled materials and block materials, precisely because the shaftless screw conveyor has no central shaft The design has great advantages for these materials. The shafted screw conveyor is suitable for conveying materials: powder, small particle materials, etc. If conveying viscous materials such as sludge, it will stick to the inner tube shaft and blades, and the conveying of blocky materials is easy to get stuck.
3. Conveying form Shaftless screw conveyor is suitable for: horizontal conveying, the maximum inclination angle should not exceed 20°, according to the actual usage.
Shaft screw conveyor is suitable for: horizontal conveying, inclined conveying, vertical conveying.
