Embodiment 1

[0008] Example 1: Refer to the attached figure 1 . A control method for filtering and recycling silicon system, which is characterized by: (1) The process graphics design is required on the touch screen, and each state can be displayed, and each parameter is set on the screen, and each alarm state is displayed, using text Display; (2) An alarm is required, and the reset is reset by touching the button. There are emergency stop buttons and washing cloth selector knobs on the electric control box; (3) There should be buttons for various actions and automatic buttons on the touch screen; stop button - --The filter press will stop working in any state of the filter press, and will be cleared in any manual state; in the automatic state, the pause button will not clear the pressure holding state; (4) The above actions are all single Step and automatic action control; (5) Water flushing. All cleaning states are effective when the cloth selection knob is in the cleaning state. The num...

Abstract

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.
