The cleaner often encounters some problems during installation and use, such as unsatisfactory cleaner effect, unreasonable design leading to rapid wear of the cleaning cutter head, and potential safety hazards caused by inadequate installation. The cleaner installed in some areas will also cause a lot of safety accidents, some places install 7~8 cleaners at a cleaning point, but the actual cleaning effect is poor, and the belt joint cracks after the cleaner is installed in some areas, resulting in the overall belt tearing problem. These problems are mainly caused by the following factors:
(1) Wrong cleaner selection.
(2) The cleaner is installed in the wrong position.
(3) The cleaner head is not wear-resistant.
Principles for choosing a cleaner
1. Installation position, chute structure
2. The position of the conveyor belt and the conveyor frame, and the position of the pressure roller
3. Conveyor belt speed and surface conditions and quality
4. The type of joint, whether it is a two-way running conveyor belt
5. The type and characteristics of the conveyed material, water content, particle size and viscosity of the material
The consequences of the belt conveyor not being cleaned in time
The materials conveyed by the conveyor belt may have sticky substances, such as coal dust, mud, and powdery materials, some of which will stick to the working surface of the conveyor belt, and cannot be completely unloaded when discharging, and will stick to the idler with the operation of the belt, which will cause the following consequences for a long time:
(1) The material enters the shell of the roller, thereby increasing the degree of bearing wear, and the material on the roller shell will damage and pull the surface glue of the conveyor belt, and accelerate the damage of the conveyor belt.
(2) When the adhesive enters the tail wheel and the reversing pulley, the material will stick to the surface of the roller, and the more sticky it is, the more it will be, causing the conveyor belt to deviate, aggravating the wear and tear of the conveyor belt, and causing adverse consequences.
(3) The material sticks to the driving roller, increasing the friction force of the roller, which will cause damage to the conveyor belt adhesive and the roller covering layer.
(4) If the material is not removed in time, a blanking area will be formed in the entire working channel, resulting in environmental pollution, an increase in cleaning labor, affecting the physical and mental health of employees, and increasing the cost of the enterprise.
Therefore, in order to ensure the normal operation of the belt conveyor, the attachment on the conveyor belt must be cleaned. The cleaner is an important part of the belt conveyor, it plays a role in cleaning the conveyor belt, and the working effect of the cleaner will directly affect the working performance, status and service life of the belt conveyor. Choosing the right set of cleaners will not only make the belt conveyor work smoothly and reliably, but also extend the life of the belt conveyor.
