Handling of common problems of belt conveyor

The Belt running deviation is the most common fault in belt conveyor working.

In order to deal with this kind of problems, attention should be paid to the scale precision of the device and the usual protection and maintenance. There are many reasons for the deviation of running, depending on different reasons.

1. Adjust the orientation of the roller group
The belt can adjust the position of the roller to adjust the deviation when running in the middle of the belt conveyor. The hole in both sides of the idler is processed for adjustment. The detailed adjustment method is to specify which side of the belt is inclined, which side of the roller group moves forward in the direction of the belt, or the other side of the belt. The lower part of the roller group should be moved to the left, and the upper part of the idler is moved to the right.

2. The device self-aligning roller group
Self-aligning roller group, there are many types such as center, four connecting rod type, vertical shaft type roller and its principle is choose to block or roller direction in the plane of the lateral thrust block or attack to heart to make the belt running deviation of the belt can be adjusted. This method is usually used when the total length of belt conveyor is shorter or the belt conveyor is running in two directions. The reason is that the shorter belt conveyor is simpler to run and not easy to adjust. This method is not the best choice for long belt conveyor, and the application of the idler can have a certain effect on the life of the belt.

3. Adjust the driving drum and turn the direction of the roller
The adjustment of driving drum and redirection roller is an important part of adjusting belt. Because a belt conveyor has at least two to five rollers, the device orientation of all the roller must be straight in the center line of the belt conveyor's length direction. If the deflection is too large, it must be deflected. The adjustment method is similar to the adjustment of roller. On the head to the right side of the drum, such as belt running deviation, the bearing should move forward, on the right side of the belt to the drum of the left side of the wandering, is on the left side of the bearing should be moving forward, can also be on the left side of the corresponding bearing seat back or on the right side of bearing seat back. The adjustment of the tail drum is the opposite of the head roller. Repeat until the belt is adjusted to the more ambitious orientation. The position of the best accurate device before adjusting is the drive or redirection of the drum.

4. Adjustment of tension
Adjustment belt tension is a very important link of belt conveyors adjustment. The two redirection rollers on the upper part of the heavy hammer should be straight in the direction of the gravity perpendicular to the gravity perpendicular to ensure the horizontal axis of their axis. When using spiral tension or oil cylinder hydraulic tensioning, the two bearing seats of the tensioning roller should be shifted together to ensure that the roller axis and belt longitudinal direction are straight. The adjustment of the detailed belt running deviation is similar to that of the roller.

5. Transfer point blanking position influence on belt running deviation
Forward the points of material blanking bearing has very big effect on the belt running deviation, especially in the two belt machine in the horizontal plane projection into straight influence is greater. The relative height of the two belt machines at the forwarding point should normally be considered. The lower the relative height, the higher the weight of the material, the greater the lateral impact of the belt on the base belt, and the material can hardly be centered. The bias of the material on the cross section of the belt causes the belt to run sideways. If the material goes to the right, the belt runs sideways to the left, and vice versa. The relative height of two belt machines should be increased in the planning process. It should be considered carefully in the ways and dimensions of the funnel, guide slot and so on. Generally, the width of the guide slot shall be the two thirds of the belt width. To reduce or prevent the belt running to increase the baffle material, change the direction and direction of the material.

6. Two-way adjustment of deviation of belt conveyor running operation
Two-way operation of belt conveyor belt running deviation adjustment than one-way belt conveyor running wide more difficult to relatively detailed adjustment should be first in one direction, and then adjust the other direction. When adjusting, you should carefully observe the link between the direction of belt movement and the tendency of running deviation, and make adjustments one by one. The main points should be in the driving drum and the adjustment of the drum, followed by the adjustment of the rollers and the adjustment of the feeding point of the material. Together, it should be noted that the belt should be evenly distributed in the direction of the length of the belt in the direction of vulcanization joint, and the force on both sides of the guide chain will be equal to the same.

The disposal of belt conveyor

The spreading of belt conveyor is a common question, and for many reasons.But the main point is to strengthen common protection and conservation.

1. The feed at the forwarding point
The scatter material at the forwarding point is mainly in the feeding hopper, guide slot and so on. If the belt conveyor is severely overloaded, the guide slot of the belt conveyor is damaged, and the steel plate of the guide slot is designed with a long distance rubber skirt, and the material can be rushed out of the guide slot. The above conditions can be used to control the transport ability, and strengthen the protection and maintenance.

2. The feed of concave section belt when hanging up
The concave section of the belt hung up when the concave section of the belt and material range when the concave section of the radius of curvature is small can make the belt dangling, belt into tank attack change at the moment, because the belt has now left the grooved roller group, usually groove Angle smaller, make out some of the material. Therefore, it is necessary to choose the larger curvature radius of the concave segment to prevent the occurrence of such conditions during the planning phase. Such as in mobile machinery on board machine, material piling and taking machine equipment in order to shorten the vehicle and the concave section of planning to form a circular arc transition interval, when the belt width is chosen redundancy is small compared to simple and material.

3. Sprinkling of the belt
When running deviation and the belt running deviation and material is due to the belt in two marginal highly attacks changed during operation, high side, but on the other side is low, the material from one side of the lower and the disposal method is to adjust the belt running deviation.
