旋转供料器输送卡住的原因及处理方法

  旋转供料器作为气力输送系统的关键设备,通过旋转的叶轮将物料从料仓均匀输送至下游管道,其运行顺畅性直接影响整个输送系统的效率。实际使用中,卡住是常见故障,多因物料特性、设备磨损或操作不当导致,需精准判断原因并采取对应措施,才能快速恢复运行并预防再次发生。

  As a key equipment of the pneumatic conveying system, the rotary feeder uniformly transports materials from the silo to the downstream pipeline through the rotating impeller, and its smooth operation directly affects the efficiency of the entire conveying system. In practical use, jamming is a common fault, often caused by material characteristics, equipment wear, or improper operation. It is necessary to accurately determine the cause and take corresponding measures to quickly restore operation and prevent recurrence.

  物料特性引发的卡住是最常见情况,需从物料状态与处理工艺两方面分析。含水量过高的物料易黏附在叶轮与壳体之间,随着输送时间延长,黏结的物料逐渐增厚,最终填满间隙导致叶轮卡滞。这类情况需在输送前增加干燥处理环节,将物料含水率控制在允许范围内,同时在供料器内壁喷涂防粘涂层,减少物料附着。含有大块杂质的物料会卡在叶轮与壳体的间隙中,尤其当杂质尺寸超过叶轮与壳体的设计间隙时,极易造成叶轮卡死。解决需在供料器上游加装筛分装置,拦截大块杂质,同时定期清理料仓底部的沉积杂物,避免杂质进入供料器。

  The jamming caused by material characteristics is the most common situation, which needs to be analyzed from both the material state and the processing technology. Materials with high moisture content are prone to adhere between the impeller and the shell. As the conveying time prolongs, the bonded material gradually thickens, eventually filling the gap and causing the impeller to jam. In such cases, it is necessary to add a drying process before transportation to control the moisture content of the material within the allowable range. At the same time, a non stick coating should be sprayed on the inner wall of the feeder to reduce material adhesion. Materials containing large impurities can get stuck in the gap between the impeller and the shell, especially when the size of the impurities exceeds the design gap between the impeller and the shell, which can easily cause the impeller to get stuck. To solve the problem, it is necessary to install a screening device upstream of the feeder to intercept large impurities, and regularly clean the sediment at the bottom of the silo to prevent impurities from entering the feeder.

  设备自身结构问题或磨损老化也会导致卡住,需从机械配合与部件状态排查。叶轮与壳体的间隙调整不当是重要原因:间隙过小会因物料颗粒进入摩擦面导致卡阻;间隙过大则易漏风,但过度调小反而加剧卡滞风险。需根据物料粒径重新调整间隙,确保既能有效密封又不阻碍叶轮转动。叶轮叶片磨损或变形会改变原有配合关系,如叶片边缘磨损后形成的毛刺易勾挂纤维类物料,积累到一定程度便会卡住叶轮。处理时需更换磨损的叶轮,对变形叶片进行校正或更换,同时选用耐磨材质制作叶轮,延长使用寿命。轴承损坏或润滑不良会导致叶轮转动阻力增大,严重时引发卡滞,需定期检查轴承状态,按规定加注润滑脂,发现轴承异响、发热时及时更换。

  Structural problems or wear and aging of the equipment itself can also cause jamming, and it is necessary to investigate the mechanical fit and component status. Improper adjustment of the clearance between the impeller and the shell is an important reason: a too small clearance can cause blockage due to material particles entering the friction surface; If the gap is too large, it is easy to leak air, but if it is excessively reduced, it will increase the risk of jamming. The gap needs to be readjusted according to the particle size of the material to ensure effective sealing without hindering the rotation of the impeller. Wear or deformation of impeller blades can alter the original mating relationship, such as burrs formed by blade edge wear that can easily hook onto fiber materials and accumulate to a certain extent, causing the impeller to become stuck. During processing, it is necessary to replace worn impellers, correct or replace deformed blades, and use wear-resistant materials to make impellers to extend their service life. Bearing damage or poor lubrication can increase the rotational resistance of the impeller, and in severe cases, cause jamming. It is necessary to regularly check the condition of the bearings, add lubricating grease according to regulations, and replace them in a timely manner if abnormal noise or heat is found in the bearings.

  操作与维护不当同样可能造成卡住,需规范流程并加强日常管理。开机前未清理残留物料是常见失误,停机后残留在供料器内的物料会因静置结块,下次启动时叶轮转动受阻导致卡住。需在每次停机前清空供料器内的物料,或在启动前手动盘车检查,确保无物料堆积。超负荷运行会使叶轮承受过大扭矩,当输送量超过设备额定处理能力时,物料在壳体内堆积,叶轮被强行带动易发生卡滞。应严格控制进料量,通过调节上游给料装置使物料均匀进入,避免瞬间过载。此外,未及时清理缠绕物会导致其缠绕在叶轮轴上,逐渐收紧后阻碍转动,需在进料口加装防护网,并定期检查清理缠绕物。

  Improper operation and maintenance can also cause jamming, and it is necessary to standardize processes and strengthen daily management. It is a common mistake to not clean up residual materials before starting up. After stopping the machine, the materials remaining in the feeder will clump due to standing, and the impeller rotation will be blocked during the next start-up, causing it to get stuck. It is necessary to empty the material in the feeder before each shutdown, or manually check the disc before starting to ensure that there is no material accumulation. Overloading operation can cause the impeller to withstand excessive torque. When the conveying capacity exceeds the rated processing capacity of the equipment, materials accumulate inside the shell, and the impeller is forcibly driven, which can easily cause jamming. The feeding amount should be strictly controlled, and the upstream feeding device should be adjusted to ensure that the material enters evenly and avoid instantaneous overload. In addition, failure to clean the wrapping material in a timely manner can cause it to wrap around the impeller shaft, gradually tightening and hindering rotation. It is necessary to install a protective net at the feed inlet and regularly check and clean the wrapping material.

  卡住故障的应急处理需遵循安全规范,避免盲目操作加剧设备损坏。发现卡滞后应立即停机,切断电源并挂牌警示,防止误启动造成危险。对于因物料黏结或杂质卡阻的情况,可打开供料器的检修孔,手动清理内部堆积的物料或取出杂质,清理后需检查叶轮与壳体是否有划伤,必要时进行修复。重启前需手动盘车数圈,确认叶轮转动顺畅后再开机,开机初期应空载运行,观察有无异响或振动,正常后方可恢复进料。

  The emergency handling of stuck faults should follow safety regulations to avoid blindly operating and exacerbating equipment damage. If the card is found to be lagging, the machine should be stopped immediately, the power should be cut off, and a warning sign should be hung to prevent danger caused by misoperation. For situations where materials are stuck or blocked by impurities, the inspection hole of the feeder can be opened to manually clean the accumulated materials inside or remove impurities. After cleaning, the impeller and shell should be checked for scratches and repaired if necessary. Before restarting, it is necessary to manually turn the impeller several times to confirm that it rotates smoothly before starting up. At the beginning of the startup, it should run without load and observe for any abnormal noise or vibration. Only when it is normal can feeding be resumed.
