The corrugated sidewall belt conveyor is a new type of belt conveyor developed in the recent more than ten years in China and it is developed and manufatured in Germany, Britain, Japan, the former Soviet Union, the United States and other foreign countries in the 1960s. It is a special belt conveyor used for materials lifting when there is limited space to refuce floor space.
The main cleaning methods of the corrugated sidewall belt conveyor is composed of the following kinds.
1 Belt beater
The belt beater is a easy and common sweeping method. it can bring about a striking effect for the dry carried materials.
1.Active beater
1.1 The RPM of the rubber belt beater should be 300 RPM ~500 RPM. Generally, the belt is driven by a triangle belt with a separate motor.
1.2 The beater should only press the tape down by 6mm~8mm .If the the required stroke of pressing down is bigger， auxiliary cleaning device should be equipped. 1.3 The beater should be installed as close to the head drum as possible
1.4 Damping rollers must be intalled underneath tensioning the belt for better cleaning effect.
1.5 The minimum diameter of the roller is 60mm
1.6 Double row spherical roller bearings should be adopted
1.7 The flapping roll can rotate by itself.
2. Passive beater
2.1 Hydraulic cleaning of head drum：If the pressure is right, the cleaning effect should be practical and desirable.
2.2 Air knife cleaner of the head drum：With enough pressure, it would have a good effect. Three installed nozzles align with each diaphragm base and the middle contacted part of the flanges.It is better for the small devices with flanges of lower 120mm. Moreover, air compressor must be equipped.
2.3 Air knife cleaner of the head drum
With enough pressure, it would have a good effect. Three installed nozzles align with each diaphragm base and the middle contacted part of the flanges.It is better for the small devices with flanges of lower 120mm. Moreover, air compressor must be equipped.
2.4 Stationary industrial vacuum system
it is applied for thin and fluid materials such as inattentive cement and sodium carbonate.
2.5 Spiral circulation system
Deploy a screw conveyor under the lower horizontal branch on the return section while the other screw conveyor is used to carry the material back to the bearing branch.
2.6 trough chain conveyor
The materials around the stern roller of an en masse conveyor could be conveyed to its bearing branches whereas compared with the above spiral circulation system the screw conveyor which is applicable for most of the devices and equipment is cheaper and less maintenance frequency.
Considering both various material properties and conveying, if the method of corrugated sidewall belt conveyor is adopt, satisfactory results can be achieved.
