Solenoid valve (73), scum is discharged through the slag discharge pipeline; sandstone mud thickness detector (76) monitors the remaining thickness of sandstone mud in real time; when the thickness of sandstone mud at the bottom is less than 2cm, the sandstone mud thickness detector (76) will The feedback signal is sent to the control system (10), and the control system (10) reduces the speed of the variable frequency drive motor (4). After 15 minutes, the control system (10) independently controls the sand scraper (74) to stop working; the upper clean water passes through the pipe Road flow to the sump;

Step 3: During the operation of the sandstone mud scraper (74), the arc-shaped scraper (742) rotates around the rotation axis (741), and the arc-shaped scraper (742) scrapes the sandstone mud deposited at the bottom to the sandstone mud sedimentation The center of the bottom of the pool (7) is discharged through the sandstone mud outlet (745);

Step 4: During the operation of the sandstone mud outlet (745), the water-containing sandstone mud enters the round steel cylinder from the sandstone mud collector (7451), and the rotating column (7455) drives the inner net winch (7454) and the outer net winch (7453) Rotate at a low speed, squeeze the water-containing sandstone mud downward, the extruded water is discharged from the fine mesh of the round steel cylinder, the dry sandstone mud is collected at the bottom of the round steel cylinder, the mud receiving plate (7456) is opened, and the bottom of the dry sandstone mud is discharged;

Step 5: During the operation of the sandstone mud collector (7451), the four inclined blades of the inclined grouting (74513) are driven by the motor and run at low speed to press down the sandstone mud; enter the squirrel cage (74515); The cage rotation (74514) drives the squirrel cage (74515) to rotate along its own axis, and throws out the sandstone mud water; the pushing and squeezing (74516) pushes the squirrel cage (74515) upward to make it squeeze and deform, and squeeze out the sandstone mud water. ; Sprayer (74512) for equipment cleaning.
