When the device works, 1-2 telescopic filter screen baffles 11 (adjacent) and the telescopic filter screens 24 are firstly disassembled to form a feeding gap, then muddy water to be dehydrated is poured (filled) into the feeding gap, and then the disassembled telescopic filter screen baffles 11 and the telescopic filter screens 24 are reassembled. Then, the oil pump is started, and pressure oil is let into the right hydraulic motor 17 and the left hydraulic motor 5 through the multi-way valve, the right input/output oil pipe 36 and the left input/output oil pipe by the control system, and further, the output shafts of the right hydraulic motor 17 and the left hydraulic motor 5 respectively drive the right threaded disc 14 and the left threaded disc 8 to rotate in an arc, so as to drive the threaded sliders 20 at the two ends of the retractable plate support 15 to move downward (i.e., move toward the center) along the guide convex strips of the right guide rail disc 12 and the left guide rail disc 10, respectively. With the descending of the expansion plate bracket 15, the space (i.e. the compression and centrifugal working chamber) between the inner wall of the regular polygon cage and the outer cylindrical surface of the outer shaft tube 37 is reduced, so that the expansion filter screen 24 and the expansion plate bracket 15 compress the mud and water, the mud and water are primarily separated, the mud and water are uniformly distributed on the outer cylindrical surface of the outer shaft tube 37, and the eccentric force can be reduced and a larger centrifugal force can be obtained when the mud and water rotate.
After the sludge is compressed to a certain degree, the motor or the engine is started, the left belt pulley 1 or the right belt pulley 23 is driven through the belt, the regular polygon cage sleeve is driven to integrally rotate, water is thrown out, and the sludge water obtains a larger linear speed and generates centrifugal force at the same time. Because mud is the solid, and moisture is liquid, mud can be stopped by flexible filter screen 24, and moisture can see through the dehydration pore on flexible filter screen 24 and be thrown away to reach the effect of quick dehydration.
After the dehydration action is finished, 1-2 telescopic filter screen baffles 11 (adjacent) and the telescopic filter screens 24 are detached again at the front part to form a discharging gap, and the dehydrated mud is discharged.
The utility model discloses a compression and centrifugal combined type mud water extractor can be used to the earth dehydration of the transportation of being convenient for after needing the dehydration, applicable in building engineering and concrete mixing plant.
