The Design And Application Of Belt Conveyer With Long Distance,Large Capacity And High Strength

With high belt speed, large capacity, high degree of automation, continuous operation and other characteristics of belt conveyor, it is the ideal equipment for conveying bulk materials. Its development has been more than a hundred years of history, are widely used in electric power, chemical, mining, metallurgy, port, coal and other industries.Industrial production rising demand, belt conveyor performance requirements are improving gradually, become the inevitable trend of the development of long distance, large capacity, high strength belt conveyor. The design theory of the subject of the long distance, large capacity, high strength belt conveyor are analyzed and the induction system, and makes a concrete analysis of the practical projects.This article analyses the frame characteristics of belt conveyer with long distance, large capacity and high strength. It studies the design theory and the calculate method on load distributing coefficient of belt conveyer with long distance, large capacity and high strength, which is verified in a project.Starting from the theory of belt conveyor, the cross section with accounting material area, check transport capacity, accurate calculation of circumferential force conveyor, determine the pulley shaft power and motor power, using point by point method is used to calculate the tension belt, the tension of each pulley and the torque transmission pulley, using the maximum tension check belt with strong, give theoretical support for long distance, large capacity, high strength belt conveyor.Considering the particularity of long distance, large capacity, high strength belt conveyor, combined with the actual operation of the general problems and solve them. Starting with the drive equipment, Soft starting system of frequency conversion is introduced, In the drive large power condition, it can realize the multi-point drive power balance, according to the working condition and can set the start time, realize the soft start of belt conveyor. To set up45degree groove rollers of belt conveyor, in under the condition of no cost increase, effectively increase the material cross-sectional area. The safety coefficient of the backstop is2times the backstop moment, make more safety for belt conveyor running. The use of frequency conversion winch take-up, control the take-up at any time, solve the problems of conventional take-up, in the large tensile condition, problem of the reaction speed is slow and difficult to control.Through specific examples of Australia SINO Iron Ore Project, from the theory and the structure of two aspects, for belt conveyor towards long distance, large capacity, and high strength design provides a train of thought. To solve the belt conveyor of the theoretical calculation and component design problems, and prove the feasibility of the method from the practical cases, so that it has more practical significance in production safety.
