1. Why is the bottom roller of the bucket elevator deformed? The rim of the bottom roller of the D-type bucket elevator is usually welded from 30 * 6 flat steel or 16-20mm diameter round steel. Due to the narrow, thin and long span of flat steel, during the operation of the lower roller, if the granular material stays between the roller rim and the tape, the flat steel will be subjected to a large squeezing force, which will cause wavy deformation in the long run. . In particular, some large materials exceeding the specified particle size are more destructive because they are forced into the wheel from the flat steel gap. Bucket elevators with severe wavy deformation of the lower roller will cause the tape to run sideways and cannot be adjusted, and sometimes even cause the hopper to fall off and the tape to break.
In order to solve the deformation of the rim, some glass factories use 4mm thick thin steel plates to weld around the rim, leaving a gap between the plate for discharging. Bucket elevator, which is similar to the thin shell structure, has good rigidity, resistance to crushing and small deformation. It has a good use effect. The disadvantage is that the discharge performance is worse than the former.
2. Why the journal of the lower roller of the hoist wears quickly: The lower roller of the bucket elevator is located at the lower part of the fuselage, close to the feed port. Due to the dust flying here, the bearing seats at both ends of the lower roller are often covered with powder. If the inspection and cleaning are not paid attention to, the seal of the bearing will be worn by the powder, and the powder will enter the bearing, which will cause the bearing rolling elements. Wear and tear of the journal of the lower roller shaft, and even scrap
Therefore, the pneumatic conveying equipment factory reminds you that in the routine maintenance of the bucket elevator, you should always keep the bearing seat clean and check the bearing seal. If it is damaged, it must be maintained in time.
