The shaftless screw conveyor is a device for rotating materials without a central shaft by a spiral body. The shaftless screw conveyor can transport materials that cannot be conveyed by conventional shaft screw conveyors and belt conveyors. Such as granular and powdery materials, wet and paste materials, semi-fluid and viscous materials, easy to entangle and easy to block materials, using fully enclosed conveying and easy to clean spiral surface to ensure environmental sanitation and materials are not polluted No leakage. Large torque and low energy consumption. Since the screw has no shaft, the material is not easy to be blocked, and the discharge port is not blocked, so that the machine can be operated at a lower speed, and the transmission is smooth and the energy consumption is reduced.

Shaftless screw conveyor daily inspection project

Check the outside and inside of the screw conveyor and remove the slag in the U-shaped tank.

Check the wear of the lining. When the wear is more than 5mm, change the lining. Do not allow the screw to directly contact the U-groove.

Check for damage to the screw (visual inspection) and axial elongation due to fatigue. When the clearance between the end of the spiral and the end of the U-shaped groove is less than 20mm, it should be adjusted and locked by the nut at the top of the drive shaft; when the adjustment amount is insufficient or there is no adjustment mechanism, the excess spiral end after elongation can be cut off. To ensure the smoothness of the operation, the spiral tail after cutting is rounded as it is.

Check that the equipment is running smoothly and that there is abnormal noise. Apply grease to the grease shaft in the drive shaft housing.

Check that the electrical wiring of the equipment is normal.

Check that the running status of the device is stable and there is abnormal noise.
