The water collecting tank 2 is provided below the dewatering outer cylinder 11, and a water outlet 21 is provided on a side wall of the water collecting tank 2. The drying mechanism 3 is respectively provided with an inlet 31 and an outlet 32 along the length direction, an inclined baffle 4 is arranged between the dewatering mechanism 1 and the drying mechanism 3, one end of the inclined baffle 4 is positioned below the sludge outlet 113, and the other end of the inclined baffle 4 extends into the inlet 31 of the drying mechanism 3.
Before using, make mud produce flocculation reaction earlier, can add flocculating agent or use the electrolytic method to make mud form the flocculence in order to reach the effect of preliminary cement separation, during the use, the mud pump of this state goes into dog-house 112, make mud get into the inside of dehydration urceolus 11, under the drive of motor 18, pivot 12 drives helical blade 13 and rotates, mud in the dehydration urceolus 11 passes through helical blade 13 to the propelling movement of mud mouth 113 direction, the moisture in the mud is continuous to be extruded by drainage hole 111 simultaneously, the mud that the moisture content is less at last drops to the inclined baffle 4 from mud mouth 113, and slide into the entry 31 of drying mechanism 3 by inclined baffle 4 and carry out the heat drying, in order to reach the effect of mud mummification. When the sludge is not discharged, one end face of the annular movable piece 15 is attached to one end face of the dewatering outer cylinder 11 adjacent to the annular movable piece, when the sludge is pushed to the sludge outlet 113 and needs to be discharged, an outward thrust is given to the annular movable piece 15, the annular movable piece 15 is displaced towards the direction of the blocking piece 14 by the thrust, at the moment, the elastic piece 16 is compressed, when the thrust is reduced (namely, the sludge discharge amount at the moment is smaller), under the action of the elastic restoring force of the elastic piece 16, the annular movable piece 15 is displaced towards the sludge outlet 113, namely, the position of the annular movable piece 15 in the horizontal direction is adjusted leftwards and rightwards according to the sludge discharge amount, so that the smooth sludge discharge is ensured. In this embodiment, the elastic member 16 may be a spring. In addition, the bottom of the water collecting tank 2 can be designed into a funnel-shaped structure, because a small amount of flocculent sludge with smaller particles can be carried in the water discharged from the water filtering holes 111, the bottom of the funnel-shaped water collecting tank 111 has the function of secondary sedimentation, when the sediment reaches a certain amount, the sediment can be discharged by using a mechanism such as a centrifugal pump, and the clear water which is positioned on the upper layer of the water collecting tank 111 and does not contain the sediment is discharged from the water discharging port 21 after reaching the certain amount.
Because the moisture in the sludge is continuously extruded and flows into the water collecting tank 2, the side of the sludge outlet 113 of the dewatering outer cylinder 11 necessarily needs a larger extrusion force to fully extrude the residual moisture, and therefore the helical blades 13 can be specifically set as follows: the pitch of the helical blades 13 is gradually reduced along the direction from the feeding port 112 to the sludge outlet 113, as shown in fig. 1, so that the extrusion force of the water in the sludge can be gradually increased to improve the extrusion efficiency.
