Fully-enclosed dustproof energy-saving anti-deviation belt conveyer
The invention provides a fully-enclosed dustproof energy-saving anti-deviation belt conveyer, and relates to energy-saving sealing improvement of an upper-layer operation carrier roller assembly of the belt conveyer and whole-course enclosed dust prevention of a receiving section, a conveying section and an unloading section of the conveyer. The belt conveyer has numerous energy consumption and easily produces dust in operation, while the existing common dust control mode can not realize better closed effect, service efficiency of dust-collecting equipment is low and belt wear is severe; and a great amount of dust still raises in the conveying section and the unloading section, so the dust problem can not be solved fundamentally. In the invention, multiple sealing assemblies are mounted with a V-shaped sealed energy-saving roller support as a fixed pivot, and a flexible material is taken as a main material for shielding dust and in seamless connection with casings of the receiving section and the unloading section casing and the sealing assemblies of a running section of the conveyer to form a membrane structural casing with multiple closed isolation chambers, thus realizing sealed dust prevention of the whole conveyer, solving the problems of belt deviation and belt wear caused by a baffle and enhancing energy-saving performance of a conveying system.
