Abstract

The invention discloses a multistage belt-type transportation centralized control device of a coal cleaning plant. The multistage belt-type transportation centralized control device comprises a multistage belt-type transportation monitoring device. A controller of the centralized control device is a PLC (Programmable Logic Controller); each-stage belt-type conveyor unloader of the centralized control device, a de-ironing separator, an electro-hydraulic overturning plate, an electric gate, a band-type brake detection switch, a contact feedback detection switch of a main contactor and an input / output endpoint of the PLC are connected. A multistage belt-type transportation starting and stopping sequence and fault processing can be monitored, meanwhile, the unloader, the de-ironing separator, the electro-hydraulic overturning plate and electric gate equipment in the coal cleaning plant are centralized and integrated, and are uniformly monitored. The centralized control device also can protect a phenomenon that the band-type brake and the contact of the main contactor are not closed.

Description

technical field [0001] This patent relates to a centralized belt transport control device, in particular to a multi-stage belt transport centralized control device for a coal washing plant. Background technique [0002] The main mode of coal transportation in the coal washing plant is belt conveying, which has the characteristics of multi-stage belt conveying. According to the requirements of the coal washing process of the coal washing plant, the start and stop methods of the multi-stage belt conveyor are as follows: under normal circumstances, the process flow of the multi-stage belt conveyor is "start in the direction of the coal flow and stop in the direction of the coal flow"; emergency stop When any equipment breaks down, stop this equipment and all equipment in the direction of coal in an emergency, and then stop the other equipment in sequence according to "following the direction of coal flow". At the same time, it is also necessary to monitor related equipment, su...
