Description

Technical Field

[0001] The invention relates to the technical field of belt transportation, and in particular to a belt return dust cleaning device and a use method thereof. Background Art

[0002] Belt conveyor is a continuous transport machine that uses a conveyor belt as a traction and load-bearing component. The conveyor belt is wound around the driving roller and various redirecting rollers, and is given appropriate tension by the tensioning device. When working, the conveyor belt is driven by the driving device and the friction and tension between the roller and the conveyor belt are used to make the conveyor belt run. Materials are continuously sent to the conveyor belt and move with the conveyor belt, thereby realizing the transportation of materials.

[0003] It is mainly composed of a frame, conveyor belt, roller, drum, tensioning device, transmission device, etc. It can be used to form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can convey both bulk materials and pieced items. In addition to pure material conveying, it can also cooperate with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow operation transportation line.

[0004] The functional characteristics of belt conveyors determine that they are indispensable in material transportation. However, in the production process, especially in the process of conveying water-containing materials with belts, due to the high viscosity of the materials, after the materials are transferred by the belt head wheel, some of the mixed materials will inevitably stick to the belt and follow the belt to the bottom of the belt conveyor. After passing through the lower rollers, a large amount of mixed materials and dust will fall to the ground. The accumulated materials not only pollute the factory environment, but also easily damage the belt conveyor.

[0005] The belt conveyor return dust cleaning device currently used mainly consists of a cleaning roller brush and a scraper driven by a chain. This system requires a large space to install. At the same time, both the cleaning roller brush and the scraper need to be equipped with a reducer as a power source, and the reducer needs to be configured in areas with severe dust accumulation. When the equipment is running, the moving parts are in areas with heavy dust accumulation, which can easily cause the reducer and scraper sprocket to malfunction, causing dust accumulation on the return journey to pollute the on-site environment.

[0006] Therefore, the applicant, based on many years of rich experience in design, development and actual production in the relevant industry, has conducted research and improvements on the existing structures and deficiencies, and provided a belt return dust cleaning device and a method of use thereof, in order to achieve a more practical purpose.
