Abstract

The invention discloses a belt speed control method of a heavy type belt conveyor with high drop height, which is mainly characterized in that: on the structural basis of the existing heavy type belt conveyor with high drop height which consists of a belt conveyor tail (2), a belt conveyor head (3), a belt conveyor roller (4), a conveyor belt (5), a speed reducer (6), an adjustable frequency motor (7), a frequency converter (8) and a resister (9) of the frequency converter, the belt conveyor tail (2) is configured with an electric generator (10) which rotates coaxially with the original adjustable frequency motor (7) so as to convert the potential energy generated by the belt conveyor when conveying materials of high drop height into electric energy and utilize the potential energy for generating electricity simultaneously when adjusting and controlling the belt speed of the belt conveyer. By utilizing the potential energy of the belt conveyer when conveying the materials of high drop height and converting the potential energy into the electric energy to replace the drive of the motive power motor through the electric generator, the invention realizes the purpose of utilizing the potential energy for generating electricity simultaneously when effectively controlling the belt speed of the belt conveyor.

Description

technical field [0001] The invention belongs to the technical field of belt speed control of high-drop belt conveyors, and mainly relates to a belt speed control method of high-drop heavy-duty belt conveyors. Background technique [0002] The belt conveyor belongs to a kind of mechanical equipment that continuously transports materials. It is an indispensable part of the rhythmic assembly line in the production process of modern industrial enterprises. It is the basic stand-alone machine in the material handling mechanization system. Its performance determines the transportation Efficiency and level of mechanization. It has strong applicability and can be used for long-distance and short-distance, large-volume and small-volume transportation, as well as the transportation of finished materials and bulk materials. Widely used in building materials, coal, metallurgy, construction, grain, chemical industry, electric power and other departments. [0003] High-drop heavy-duty b...
