Shaftless screw conveyor can convey materials that traditional shaft screw conveyors and belt conveyors cannot or cannot easily convey, such as granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, easy to entangle and block Materials, materials with special hygiene requirements.
, 由于采用了无中心轴设计 , 利用具有一定柔性的整体钢制螺旋推送物料 , 因而具有以上突出优点，环保性能好。 The performance characteristics of the shaftless screw conveyor are: Compared with the traditional shafted screw conveyor , the shaftless screw conveyor has the above outstanding advantages due to the use of a non-center shaft design and the use of a flexible overall steel screw to push the material . , Good environmental performance. Compared with the screw conveyor with shaft, the weight and cost will be reduced a lot.
1. Good environmental performance. The fully enclosed and easy-to-clean spiral surface can ensure that the delivered materials will not be contaminated and will not leak and convey the materials.
1.5 倍。 2. The conveying amount is large, and the conveying amount is 1.5 times that of the screw conveyor with the same diameter .
3 , large torque, low energy consumption, the discharge port is not blocked.
60~70m 。 4. Long conveying distance, single machine conveying length can reach 60 ~ 70m .
5 , compact structure, save space, beautiful appearance, easy operation, economical and durable.
Common causes of bladeless shaft screw conveyor damage and solutions
1. The blade is too thin. Because the shaftless screw conveyor lacks an intermediate shaft, all the stress points are on the blade, so the thickness of the blade has a very important impact on the actual use of the device. Choosing an appropriate thickness of the spiral blade directly affects the use of the shaftless screw conveyor.
2. The wheelbase of the blade is too small, and the diameter of the spiral tube is not selected properly. When conveying powder or flakes, the blade's wheelbase is too small, which causes excessive squeezing force, which directly damages the blade. As the shaft rotates, the thicker blade will also cause some damage. Another reason is that the smaller diameter of the pipe will also cause excessive pressure. Causes severe blade damage. After taking the above two measures, the blade speed can be reduced at the same time. To achieve this effect.
