Energy saving system of belt conveyor and energy-saving control method thereof

Abstract

The invention relates to an energy saving system of a belt conveyor and an energy-saving control method of the energy saving system of the belt conveyor. The energy saving system of the belt conveyor comprises a system starting button, a belt conveyer, a material detection device, a signal transformer, a belt conveyer drive motor, a frequency converter and a programmable controller. The belt conveyer is provided with a conveyer belt and the belt conveyer drive motor. The material detection device is installed right belowunder the conveyer belt and connected with the programmable controller through a signal line. The system starting button is connected with the programmable controller which is connected with the belt conveyer drive motor through the frequency converter by controlling the signal line. The belt conveyer system realizes the automatic control state of ''high speed with materials and low speed without materials''. According to the energy saving system of the belt conveyor and the energy-saving control method of the energy saving system of the belt conveyor provided by the invention, the idle time and idle energy consumption of the belt conveyer can be effectively reduced, so that the system mechanical loss generated in the time is reduced, the work efficiency is remarkably improved, the electric energy loss is reduced, and the purpose of saving energy and reducing consumption is realized.

Description

technical field [0001] The invention relates to an energy-saving system for a belt conveyor and an energy-saving control method thereof, which are suitable for an energy-saving and consumption-reducing system matched with a belt conveyor for material transportation. Background technique [0002] Belt conveyor is a widely used transmission machinery. The energy consumption of the belt conveyor is mainly divided into two parts. One is the energy consumption generated by the work done by moving and lifting materials, which must be paid for material handling. The other part is the mechanical loss of the system, including the frictional resistance between the belt and the idler, the resistance of the cleaner and the guide trough, and the efficiency loss of the motor and reducer. This part of energy consumption, no matter whether there is material on the belt conveyor or not, as long as the belt conveyor is running, it will be paid. [0003] In the process of material transpo...

Problems solved by technology

Therefore, the longer the belt conveyor in the process, the more the number of transfer belts, the longer the idling time of each downstream belt conveyor in the state of no material, the higher the mechanical loss of the system, but the transportation volume has not increased, resulting in the unit output The rise in energy consumption is a serious waste of energy

[0004] In the process of material transportation, the belt conveyor system is often operated with no load or low load, such as moving the cabin during dock loading, etc. Since there is no material loading during these processes, the belt conveyor can only run idly, and energy is wasted; and if the The entire process is stopped and restarted after the existing work is completed, which will cause a longer start-up time and lower operating efficiency
