There are many devices at inside and outside on the bucket elevators. Spill protection device is one of the various devices. Bucket elevators use this device to reduce the overflow of materials, which directly affects the efficiency of material transportation. Below, the editor has sorted out the relevant information, telling you in detail the function of the bucket elevator overflow protection device. The so-called bucket elevator overflow protection device is to install a reed switch in a plastic box, lead out a two-core cable, a magnet, and install a gate on the chute. Fix the reed pipe on the chute. The magnet is stuck on the gate. During normal operation, the reed switch is close to the magnet, and the reed switch is closed. The normally closed point controls the contactor coil when blocking occurs. The material pushes the gate open, the magnetic steel leaves the reed switch, the reed switch is disconnected, and the bucket elevator is locked and shut down.
In the process operation of bucket elevator , it is not allowed any opposite conveying. However, opposite conveying is often found on job site.How to deal the opposite conveying with solutions ? You can take the following tips as a reference. When there are some materials remaining inside the bucket while drive motor has stopped running ,the buckets suspended on both sides of the upper roller will reverse due to the unequal weight, and those buckets with the material will fall down under the action of gravity,such an opposite rotating will result in a huge impact loading.Worse still ,it can cause buckets partially detached and screw bolts are pulled out .In order to prevent bucket elevator from reverse conveying ,usually we can design a backstop device on the driving shaft.There exist many back stop device in the markets. Different back up device have their own requirements .So we need choose a suitable back up device according to actual production needs . Well,that is up for today. Hope this article will be useful to you .
