Bucket elevator material reflux analysis
Bucket elevators in operation, if the downstream or upstream cylinder barrel has material from the nose section down shaking down, a phenomenon known as reflux. Reflux occurs
hoist to centrifugal discharge type mostly transportation of materials, mostly granule-like, there are small flakes or crushed powder mixture
. Material back too, will make the delivery of bucket elevators decline, food grain crushing rate increased. For large capacity hoist, also undermine the drive mechanism
components, such as burning motor, pull off the belt or the injection fluid coupling, which in any case are
Cause interruptions in production, resulting in economic losses.
Backflow caused by many factors, mainly the bucket elevator should discharge to analyze the situation. In the process of centrifugal discharge hopper wheel running around the
head and the tangential speed of the outer edge of the material within the hopper mouth of slip speed, determines the stripped material hopper instantaneous speed of the
direction of movement
. Furthermore, the full extent of the hopper, the hopper determines the starting time of discharge, and the discharge end time of day, it depends on the geometry of the hopper.
This shows that the material in the hopper head office after leaving the flight path, the influencing factors are: wire-speed hopper, hopper shape and materials
Properties. If the head cover can be made of all the flight envelope of the trajectory line, the hopper of the material can be stripped from the housing block, the discharge
port falls smoothly, it is non-contact type discharge. In most cases, taking into account the manufacturing costs, the head designed Metal detector for food to be relatively small, throw
Grazed machine head cover material discharge port toward the wall, which is oriented discharge. When the material is determined, whether a return, its determinants are: wire-
speed, bucket shape and nose shape. It also constitutes a bucket elevator design three elements.
With the construction of the development of the grain distribution, grain bucket elevator variety and volume also increased, while the return of the phenomenon also occurs. When
significant excess return, we must address Airport conveyor the main factors to take effective measures to solve them. Generally speaking, the hopper does not result
Caused by reflux and must be replaced hopper.
