Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor transportation, and particularly relates to a long-distance belt conveyor cleaning roller device for materials containing slag and water. Background Art

[0002] When the belt conveyor transports materials with a high water content, the materials tend to adhere to the working surface of the belt conveyor. The existing technology usually uses a cleaning device to clean the materials from the working surface. However, when the cleaning device is not adjusted or replaced in time, the cleaning effect of the cleaning device will decrease, and the residual materials adhering to the working surface will be brought to the relevant operating parts of the belt conveyor by the rotating layer of the belt conveyor working surface and accumulate there. If it is not cleaned in time, the materials will easily become hardened over time, wear the operating parts of the belt conveyor, and affect the on-site environment. When too much material is accumulated under the rotating layer, the hardened materials will block the drainage channel and cause wastewater to overflow. Excessive accumulation of materials will hinder the replacement of rollers. Especially on belt conveyors enclosed with "machine covers", the adverse effects of residual materials on belt conveyors are particularly obvious. Utility Model Content
