The invention relates to a method for controlling a
silicon filtering and recycling
system, which has convenient and visualized control, high filter efficiency and thorough cleaning and has the control steps of compacting, filtering, cleaning 1, cleaning 2, squeezing, draining water, blowing air, blowing air 2, blowing back, returning
stroke, opening a turning plate, discharging by a pull plate and closing the turning plate, wherein the cleaning process comprises the following steps of: cleaning secondary compacting, cleaning secondary return
stroke, moving ahead of a cleaning car, descending a frame, ascending the frame, moving the pull plate forward, moving the pull plate backward, returning the pull plate and returning a dolly; and an electric cabinet is provided with an
emergency stop button and a cleaning cloth selection turn button. The invention has the advantages that the
silicon filtering and recycling
system is controlled by a PLC and displays through a touch screen, thereby having visualized and convenient control; the plate pulling and the
rapping are performed at the same time, thereby shortening the time for discharging cakes and enhancing the filter efficiency; and the secondary cleaning is adopted, thereby having thorough cleaning.
