Working Principle of Bucket Elevator The conveying working principle of bucket elevator is: the hopper scoops up materials from the storage below, lifts them to the top with the conveyor belt or chain, bypasses the top wheel and then flips downward, and the bucket elevator The machine pours the material into the receiving tank. The transmission belt of a belt-driven bucket elevator generally uses a rubber belt, which is installed on the lower or upper driving drum and the upper and lower redirecting drums. Chain-driven bucket elevators are generally equipped with two parallel transmission chains, a pair of transmission sprockets above or below, and a pair of redirecting sprockets below or above. Bucket elevators are generally equipped with a casing to prevent dust from flying in the bucket elevator.
Characteristics of bucket elevator
It has small driving power, adopts inflow feeding, induced discharge, and large-capacity hopper intensive arrangement. There is almost no material return or excavation when the material is lifted, so the ineffective power is low.
. Wide lifting range. This type of elevator has few requirements on the type and characteristics of materials. It can not only lift general powdery and small granular materials, but also materials with greater grindability. Good sealing and less environmental pollution.
Long service life, the elevator adopts an inflow type of feeding, no need to use a bucket to dig materials, and there is little extrusion and collision between materials. This machine is designed to ensure that materials rarely scatter during feeding and unloading, reducing mechanical wear.
, Good operation reliability, advanced design principles and processing methods ensure the reliability of the entire machine operation, with a failure-free time of more than 10,000 hours. Lift height is high. The hoist operates smoothly and therefore can reach high lifting heights.
Advantages and Disadvantages of Bucket Elevator
Advantages: Simple structure, small horizontal size, and small floor space.
, large lifting height, good conveying capacity, fully enclosed fuselage, little environmental pollution.
Low power consumption.
Disadvantages: It is easy to block when overloaded, and the hopper is easy to wear.
It is only suitable for transporting powdery and small and medium-sized bulk cargoes, such as grain, coal, sand, etc.
Cannot transport goods in the horizontal direction.
Precautions for the use of bucket elevators
During operation, the principles of starting without load and stopping without load must be followed. That is to say, start the machine first, wait until the operation is normal, and then empty the material in the machine before feeding and stopping.
When working, the feed should be even and the discharge pipe should be smooth to avoid clogging. If there is a blockage, the feed should be stopped immediately and the machine should be stopped, and the machine base plug-in plate should be opened to remove the blockage. Note that you cannot directly reach into the base with your hands at this time.
During normal operation, the hopper belt should be in the middle of the barrel. If deviation is found or the bucket belt is too loose, causing collision and friction between the hopper and the barrel, it should be adjusted in time through the tensioning device.
Strictly prevent large foreign objects from entering the machine base to avoid damaging the hopper and affecting the normal operation of the bucket elevator. When conveying materials that have not been initially cleaned, an iron grid should be installed at the feed inlet to prevent fibrous impurities such as straw, wheat straw, and rope from entering the machine base and causing entanglement and blockage. , The tension of the elevator hopper belt should be checked regularly, and whether the connection between the hopper and the hopper belt is firm. If looseness, falling off, skewing or damage of the hopper are found, it should be repaired or replaced in time to avoid more serious consequences.
If a sudden shutdown occurs, the accumulated materials in the machine base should be discharged before starting the machine.
