Described folded ring squeezes the filter dewatering unit, it is characterized in that: the cone-type spiral axle tapering be 3%～7%, the screw thread of cone-type spiral axle from the sewage inlet end from coil to coil around to sludge outlet and whenever around a circle pitch all from coil to coil reduce 5%～15%.
Described folded ring squeezes the filter dewatering unit, it is characterized in that: fixed plate is square.
When the utility model uses, mix sewage that mud is arranged and enter from the sewage inlet of housing, when the cone-type spiral axle rotated, movable plate can move to the sludge outlet direction while rotating along with the screw thread of cone-type spiral axle; Because the pyramidal structure of cone-type spiral axle, the cavity volume of housing reduces to sludge outlet gradually from sewage inlet, under the rotation of cone-type spiral axle promoted, mud is this terminal point motion from this starting point of sewage inlet to sludge outlet, and the mud in the housing inner chamber diminishes along with the space and is compressed; Movable plate was moved by the screw thread ejection of cone-type spiral axle when the cone-type spiral axle rotated, to keep the slit between movable plate and the fixed plate not blocked, moisture under the effect of pressure in the mud is extruded by the slit between movable plate and the fixed plate, mud after squeezing the water out finally is extruded from sludge outlet, can control the water ratio of the mud that is discharged from by the tightness of adjusting spring between sludge outlet side panel and the housing.
The utlity model has following beneficial effect: 1. the granule content wide accommodation of pair sewage, can use from general sewage to water-containing sludge, do not need pre-treatment; 2. filter effect is stable, can contain dirty granular size according to the accurate adjusting water outlet of spacer thickness; 3. squeeze pressure is large, can make the mud extraction water ratio low.

Embodiment
Below further specify the utility model by specific embodiment.
A kind of folded ring squeezes the filter dewatering unit, comprise housing 1, cone-type spiral axle 21, screw rod 22, fixed plate 31, movable plate 32 and pad 33, such as Fig. 1～shown in Figure 5, concrete structure is: the two ends of housing 1 are respectively with 11 sealings of a panel, one end of housing 1 is provided with sewage inlet, shown in the A among Fig. 1, the other end of housing 1 is provided with sludge outlet, shown in the B among Fig. 1, the sidewall of housing 1 is provided with water port, shown in the C among Fig. 1, the two ends of cone-type spiral axle 21 are separately fixed on two panels 11 of housing 1 by bearing, the less end in cone-type spiral axle 21 cross sections is fixed on the panel 11 of sewage inlet side, the larger end in cone-type spiral axle 21 cross sections is fixed on the panel 11 of sludge outlet side, the panel 11 of sludge outlet side is fixed on an end of housing 1 by spring, the screw thread of cone-type spiral axle 21 from the sewage inlet end from coil to coil around to sludge outlet and whenever around one the circle pitch all from coil to coil reduce; Screw rod 22 has four, and the two ends of four screw rods 22 are fixed with an angle of two panels 11 respectively; Fixed plate 31 is square, and the middle part of fixed plate 31 has circular through hole, respectively opens a fixed orifices on four angles of fixed plate 31, and four holes of fixed plate 31 are enclosed within respectively in four screw rods 22; Movable plate 32 is annular, and every movable plate 32 all is located between two adjacent fixed plates 31, and every movable plate 32 all is fixed on the circle screw thread of cone-type spiral axle 31, and the external diameter of movable plate 32 is less than the internal diameter of fixed plate 31 middle through-holes; Pad 33 is enclosed within respectively in four screw rods 22, and is provided with a slice pad 33 between two adjacent fixed plates 31.
