How to solve the problem of excessive feeding and hopper falling off of bucket elevator?
Machine failure is inevitable. What we need to do when using the machine is to reduce the probability of machine failure and eliminate the failure in time. Bucket elevator used for material transportation is a kind of transportation equipment often used in major factories. When using bucket elevator to transport materials, it is inevitable to encounter faults, such as excessive return and hopper falling off, which are two common faults. Next, I sorted out these information and told you the specific solutions!
abnormal returns
Hoist return refers to the scene that some materials return to the hoist frame without being unloaded from the machine at the unloading position. In the hoisting process, if the hoist returns too much material, it will inevitably reduce the consumption efficiency and increase the power consumption and material integrity rate. Many reasons for returning goods are as follows: 1. The hopper runs too fast. When the elevator lifts different materials, the operation speed of the hopper is different: generally, when lifting boring powder and granular materials, the speed is about 1 ~ 2m / S; When lifting block materials, the speed is 0.4 ~ 0.6m/s; When wet powdery and granular materials are lifted, the speed is 0.6 ~ 0.8m / if the speed is too high, the unloading is in advance, forming a return. At this time, the speed of the hopper shall be appropriately reduced according to the lifted materials to avoid material backflow.
2. The discharge tongue at the inlet of the machine head shall be installed uniformly. If the tongue is too far away from the discharge position of the hopper, it will cause material return. Adjust the position of tongue plate in time to avoid material return.
Hopper falling off
It refers to the process that the belt falls off from the hopper. Abnormal noise will be generated when the hopper falls, which needs to be stopped in time to reflect, otherwise it will cause more deformation and falling of the hopper; When connecting the hopper position, the hopper belt is torn. The non mainstream reasons for hopper falling are as follows: 1. Excessive feeding causes the accumulation of materials on the base, the increase of lifting resistance and the poor operation of the hopper, which is the direct reason for the falling and deformation of the hopper. At this time, stop the machine immediately, take out the lower insert plate on the base, remove the deposits on the base, replace the hopper with a new one, and then start production. At this time, reduce the feeding amount and try to be uniform.
Bucket elevator shall be operated and used by professionals. Professional training shall be conducted for operators to make them understand the basic use methods of bucket elevator and avoid problems caused by improper use of the machine.
It is also necessary to strengthen the daily inspection of the machine, inspect the machine on time, and keep the records of each inspection. In case of any problem, it shall be reported to relevant personnel in time and handled in time. In particular, the inspection of belts, gears, chains and pulleys can be completed by touch and observation.
If you are the operator of the bucket elevator, if you encounter too much material return or hopper falling off in the process of using the bucket elevator for material operation, you can solve it according to the above methods. As mentioned above, the operation of bucket elevator needs professional training, and the correct operation of bucket elevator is also a good way to reduce machine faults. We should keep improving in our work and constantly strengthen the operation knowledge of bucket elevator, so as to reduce the probability of problems in material transportation.
