The mud density that (3-1-4) detects filter screen (3-1-2) surface is less than 2g/cm3When, filter screen mud density detector (3-1-4)
Detection signal is fed back into Programmable Logic Controller (10), Programmable Logic Controller (10) stops electric cleaning brush (3-1-3)；
4th step：During drainage collecting (4) collects drainage, pressure detecting table (4-1) monitor in real time extruding grid (3-
1) hydraulic pressure value；When it is higher than 15MPa that pressure detecting table (4-1) detects the hydraulic pressure extruded in grid (3-1), pressure detecting table (4-
1) feedback signal is sent to Programmable Logic Controller (10), Programmable Logic Controller (10) opens drainage flow probe (4-3), prison
Control drainage changes in flow rate, drainage is entered into drainage collecting pit (5) through circulation duct (4-2)；When pressure detecting table (4-1) detection
When being less than 4MPa to the hydraulic pressure in extruding grid (3-1), feedback signal is sent to Programmable Logic Controller by pressure detecting table (4-1)
(10), Programmable Logic Controller (10) closes drainage flow probe (4-3), it is stopped monitoring work；
5th step：Material location probe in mud cake surge bunker (6) to the controlling level real-time monitoring of mud cake, when material level detection
When the controlling level that device detects mud cake is higher than 12cm, Programmable Logic Controller (10) opens the discharging of mud cake surge bunker (6) bottom
Door, mud cake enters into mud cake and collects in go-cart (7).
