Description

Technical Field

[0001] The invention relates to the field of belt conveyors, and in particular to a self-cleaning belt conveyor and a belt cleaning method. Background Art

[0002] Belt conveyors are often used to transport powders. For some sticky powders, after long-term use, the powders are easy to stick to the belt surface. If they are not cleaned regularly, it is easy to affect the normal operation of the belt conveyor. For example, the Chinese patent with patent number CN202221219224.8 provides a belt cleaning device for a belt assembly line, including an assembly line frame and a belt conveyor, wherein two groups of fixed frames are fixedly installed at the bottom of the assembly line frame, and a slide groove is opened on the fixed frame, and a rotating bearing that can be adjusted to rise and fall is slidably installed in the slide groove, and an adjusting screw is threadedly installed at the bottom of the fixed frame; through the fixed frame, the utility model installs a plurality of groups of cleaning brushes distributed in a circular array, and then a plurality of groups of cleaning brushes are driven by the pulley to stick to the bottom surface of the conveyor belt of the belt conveyor for cleaning, and the pulley can be driven to rotate by another motor, and the two groups of fixed frames can be rotated synchronously to adjust the height of the cleaning brush, thereby adjusting the contact effect between the bristles of the cleaning brush and the surface of the conveyor belt; in addition, the water outlet nozzle arranged on the side of the cleaning brush can circulate and flush multiple cleaning brushes, thereby ensuring the continuous cleaning effect of the device. The belt cleaning mechanism in the prior art, such as the one mentioned above, mainly cleans the belt surface by spraying water. For some powders with high viscosity, after they adhere to the belt, it is difficult to effectively remove them by flushing. They need to be soaked in special chemical cleaning agents to make them fall off. When flushing is used, the contact time between the agent and the belt is short, and the cleaning effect is poor.
