Belt conveyor system consist of conveyor belt, pulley, idlers, frame, tension devices, driving unit, protection switches and other components etc.
Belt conveyor system is widely used in mining, metallurgy, port, cement, grain, chemical and other industries. The conveyor belt is an important part of the belt conveyor system. Today, let's talk about some problems of the conveyor belt in the process of use.
1 The basic law of conveyor belt deviation
Conveyor belt deviation is a common accident of belt conveyors. In production, people have summed up the basic law of conveyor belt deviation through practice and exploration. In order to provide a reliable basis for the prevention and treatment of accidents, the following is the basic law of conveyor belt deviation.
(1) Too large not too small, the diameter of the roller and the roller is different, and the conveyor belt will run to the large side in the process of operation.
(2) It is on the high side but not on the low side. The support device causes both sides of the conveyor belt to be not on the same horizontal plane, so the conveyor belt will deviate from the high side in operation.
(3) too tight and not too loose. The tightness on both sides of the conveyor belt is different, and the conveyor belt is running to the tight side.
(4) If the idler or roller is not on the vertical section of the running direction and one side is behind and the other side is in front, the conveyor belt will deviate from the backward side during operation.
2 Reasons For Conveyor Belt Deviation
Two diameters of the driving drum or the tail drum are different;
There is coal slime or other radiating material on the surface of the drum or roller;
Main reasons for conveyor belt deviation:
Two diameters of the driving drum or the tail drum are different;
There is coal slime or other radiating material on the surface of the drum or roller;
The head drive drum is not parallel to the tail drum;
The center line of drive drum and tail drum shaft are not vertical to the center line of the fuselage;
Roller installation is not correct;
Feeding position is not right;
The drum center is not on the fuselage center line;
Conveyor belt joint is not straight or aging deterioration of conveyor belt caused by deflection on both sides;
The fuselage is not straight.
3 The harm of conveyor belt deviation
Conveyor belt deviation will not only affect production, damage conveyor belt. When the non-flame retardant conveyor belt is used, it will also increase the running resistance of the conveyor belt due to deviation, making the conveyor belt slip, which may cause mine fire accidents.
4 Conveyor belt deviation prevention and treatment
Preventive measures
Improve installation quality;
Improve the quality of conveyor belt joints;
Strengthen tour inspection and maintenance;
Ensure unbiased loading;
Ensure that the cleaning device is normal.
