Energy-saving control device for belt conveyor units

Abstract

The invention provides an energy-saving control device for belt conveyor units. The energy-saving control device comprises a belt conveyor unit composed of a plurality of belt conveyors. Each belt conveyor is provided with a slave controller. The slave controllers are all interactively connected with a master controller. The input end of the slave controller is connected with the output end of each of a material sensor, a belt speed sensor, an emergency stop sensor and a performance detection unit disposed on the corresponding belt conveyor. The output end of each slave controller is connected with a start / stop button of the corresponding belt conveyor. The slave controllers on the belt conveyors are all interactively connected with the master controller, actual time of the former belt conveyor serves as delayed start time of the second belt conveyor, and accordingly start or stop time of each belt conveyor is more accurate; chances of the belt conveyors being idle are avoided, transporting efficiency is improved, normal effective transport modes are ensured, energy resources are saved, and the service lives of the belt conveyors are prolonged.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to an energy-saving control device for a belt unit. [0002] Background technique [0003] Belt conveyors, also known as belt conveyors, are widely used in many industries of the national economy, such as coal mines, ports, power plants, industrial production and other fields, especially the main transportation equipment for underground coal mine operations, responsible for transporting coal, The task of transporting gangue and so on. In practical applications, in order to meet the needs of cargo transportation, a belt unit composed of multiple belt conveyors is often used to undertake the entire transportation work. The combination of these belt units is very long, the shortest is several hundred meters, and the longest is several kilometers or even Dozens of kilometers. When the goods arrive, it is necessary to start each belt conveyor in the belt unit...

AI Technical Summary

Problems solved by technology

Although the belt unit has implemented centralized control and one-button start or stop, it is impossible to fundamentally avoid the idling phenomenon of the belt conveyor, because each belt conveyor has different conditions and different speeds, and the uniformly set delay time cannot meet the requirements of each belt conveyor. Therefore, some belt conveyors still have a long-term idling phenomenon; if one of the belt conveyors fails and causes the idling of the belt conveyor, resulting in a serious waste of electric energy
