Bucket elevator is a vertical conveying mechanical equipment, usually used to vertically transport bulk grains or powders from bottom to top. Its specific characteristics are: small cross-sectional area; Compact layout of transportation system; Greatly improve height and conveying capacity; Has good sealing performance and requires less power. The current wear-resistant and special plastic material is used to make a one-time molded dustbin, which can be used in both dry and wet conditions. The flat belt adopts high-strength plate belt, which can effectively extend the service life of the plate belt. Some upper and lower transmission wheels are wrapped with rubber, which can increase the friction between the belt and the transmission wheel, and prevent slipping when lifting materials.
How to maintain the hoist?
1. Drive with no load. So before each shutdown, all materials in the hopper should be drained before stopping.
2. Cannot reverse, reverse may cause chain derailment, troubleshooting derailment is very troublesome.
3. Feed evenly and do not suddenly increase the feeding amount. The feeding amount cannot exceed the conveying capacity of the elevator. Otherwise, it is easy to cause material accumulation at the bottom, and in severe cases, a "stuck car" accident may occur.
4. Timely and appropriately replenish lubricating oil.
5. When the chain and hopper of the small hoist are severely worn or damaged, they should be replaced in a timely manner.
In addition to the basic maintenance of the hoist mentioned above, regular inspections of the equipment are also necessary!
1. During the operation of the grain bucket elevator, there should be fixed personnel who have the technical skills to use the bucket elevator and are familiar with its performance.
2. The specified conveying material characteristics, conveying capacity, and working conditions of the grain bucket elevator should be strictly followed.
3. The using unit shall formulate maintenance and operation procedures for the bucket elevator, and the supervisory personnel shall regularly inspect the bucket elevator and strictly implement the shift handover system.
4. All inspection doors of the grain bucket elevator are closed during operation, and lighting equipment is installed in the upper and lower sections and frequently opened inspection doors.
5. If the grain bucket elevator malfunctions during operation, it should be stopped immediately and maintenance is prohibited while in operation.
6. Operators should regularly check the operation of the bucket elevator. Including whether the tape is deformed and worn, whether the tightness is appropriate, whether the hopper is skewed or detached, whether the fasteners are loose, whether there is oil at the lubrication point, and whether there is blockage at the feeding port and bottom of the material.
7. The tensioning device in the lower section should be adjusted appropriately to ensure that the tape has the tension required for normal operation.
8. If there is a phenomenon of material return during the upper unloading, the sliding plate of the unloading port should be adjusted to maintain an appropriate gap between the edge of the sliding plate and the edge of the hopper, which can be between 10-20mm.
9. If the bottom is blocked by accumulated material, the lower cleaning door should be opened for cleaning.
10. The grain bucket elevator should start with no load, do not feed before stopping, and stop after unloading.
11. The user should specify the maintenance cycle according to the usage conditions of the bucket elevator.
12. The lubrication of the grain bucket elevator should be carried out according to the lubrication items specified in the lubrication project, combined with the operating conditions.
