Power plant lime -ash scraper conveyor chain rupture automatic check out system

Power plant lime -ash scraper conveyor chain rupture automatic check out system belongs to the automatic control field, including scraper conveyor the last automatic checkout device that connects of scraper conveyor, automatic checkout device include cam, proximity switch, and the cam is connected on scraper conveyor's chain drive's driven shaft, and proximity switch connects in scraper conveyor's frame and set up in one side of cam, proximity switch's signal output part connects DCS control system, and DCS control system connects the touch -sensitive screen, scraper conveyor still connects the field control case, field control case connection control cabinet, and the switch board is connected with DCS control system. After scraper conveyor metal chain disconnection, signal that automatic checkout device detected calculates the judgement through the communication cable teletransmission to DCS control system to the major loop moves in delivering to the switch board through teletransmission cable output control signal, and supply interruption makes the scraper conveyor bring to rest.
