The reason for the large amount of material return in the bucket elevator

Summary. Hello friends, such a hoist has too much material to return, which can only mean that the gap between the inner plate is too large. As long as you adjust the spy, or put a little less material, so that it has enough space, so that you can have less return material.

This is not a problem of performance, just the reason for operation, first see if its gap is large, if there is no problem, then put less material, do not put too much at one time.

What should I do if there is too much material returned by the bucket elevator?

Hello friends, such a hoist has too much material to return, and it can only be said that the gap between the inner plate is too large. As long as you adjust the treacherous, or put a little less material, so that its space is large enough, so that you can reduce the disturbance of the return beam. This is not a problem of rolling performance, but the reason for the operation, first see if its gap is very large, if there is no problem, then less material, do not invest too much at one time.

When the corn germ is raised, there is more corn husk in it.

Oh. If you are referring to the excluded jade or imperial rice skin is not complete, it means that the gap is small, not large. Adjust the place where the waste is produced and you can transport it in the stove, or make a few more holes to let it spray the corn husks.

Bucket elevator loading is the process by which the hopper digs up material as it passes through the lower half of the base. According to the different loading directions, there are two kinds of forward feeding and reverse feeding in the charging mode, and the more commonly used in engineering practice is reverse feeding, and the feeding direction is opposite to the hopper movement direction at this time, and the filling coefficient is larger.

It is worth noting that the hopper starts from the horizontal centerline of the bottom wheel to the horizontal centerline of the head wheel, and the material will rise vertically with the hopper, that is, the lifting process. At this time, it should be ensured that the spring head belt has enough tension to achieve a smooth lifting and prevent the occurrence of sprinkling.

Bucket elevator unloading process: the unloading method has centrifugal type, gravity type, digging type charging and mixing type 1, centrifugal type is suitable for fluidity, good scattering of materials 2, more moisture, poor scattering of materials should be used gravity type unloading 3, the design of the choice of mixed or gravity way of unloading, digging type loading, the selection of ZH type (medium and deep bucket) hopper, the traction part for the low alloy high-strength ring chain, after appropriate heat treatment, has high tensile strength and wear resistance. The lower part uses a heavy hammer lever tensioning device to achieve automatic tensioning.

4. The mixed discharge has good adaptability to the material, and is more commonly used in the actual project. The manufacturers with good quality of bucket elevators have Hebi General, and they have been cooperating with them.

The reason for the deformation of the hopper of the bucket elevator is analyzed, on the one hand, it is the extrusion of the bottom compacted material layer and the heavy hammer, and on the other hand, the strength of the hopper itself is not enough. How to improve the strength of the hopper without greatly increasing the weight of the hopper is the key to the problem.

The damage to the front mouth of the hopper is mainly caused by the extrusion with the harder layer of cemented material.

Bucket elevatorIt is divided into deep buckets, shallow buckets and triangular buckets. According toBucket elevatorThe different working speed and the characteristics of the material to be transported can be used in different hopper forms. The angle between the bucket and the back wall of the hopper is large, and each hopper can be loaded with more materials, but it is difficult to unload, which is suitable for transporting dry loose materials; The angle between the hopper in the shallow hopper and the back wall of the hopper is small, and the loading capacity of each hopper is small, but it is easy to empty, which is suitable for transporting wet and viscous materials.

Deep and shallow buckets are fixed on the traction member at a certain distance in the bucket lifting and along the length of the traction member. The deep bucket is a triangular hopper with a guide side, this hopper adopts a dense arrangement one after another in the elevator, when bypassing the upper sprocket discharge, the two guide sides of the previous hopper and the front wall form the unloading guide groove of the latter hopper, this hopper is suitable for conveying heavier, semi-abrasive, abrasive block material.

After the bucket elevator material fell off and deformed, we learned about and followed up with the user, and finally found that the main reasons were: too much feeding and the accumulation of materials in the machine base; The position of the feed port is too low, and the hopper holds the material coming in from the feed port by itself when lifting; The material of the hopper is not good, and the load-bearing is low; There is accumulation in the hopper, which is caused by too much impact on the hopper when the machine is turned on.
