Abstract
The utility model discloses a stacked screw type sludge dewatering machine provided with a wear-resistant skirt of a screw shaft. The wear-resistant skirt is embedded on an outer edge of a blade of the screw shaft, and the width of the wear-resistant skirt is larger than that of the outer edge of the blade of the screw shaft. The middle of the wear-resistant is provided with a skirt groove, and solid lubricating mater is arranged in the skirt groove.
Description
Technical field
The utility model relates to the device of a kind of mud and sewage solid-liquid separation, especially relates to a kind of folded spiral shell formula sludge dewatering equipment, and this folded spiral shell formula sludge dewatering equipment is applicable to the sludge dewatering in the WWT.
Background technology
The folded spiral shell formula sludge dewatering equipment of prior art; Dehydration portion and concentrated portion are by screw shaft and be enclosed within the outer set collar of screw shaft and form with the ring that moves about; The internal diameter of set collar is slightly larger than limit, the outer diameter of spiral shaft vane, and the internal diameter of the ring that moves about is slightly less than limit, the outer diameter of spiral shaft vane, constantly the ring that moves about is promoted through the rotation of screw shaft; Making the ring that moves about do radially and move about, thereby playing the effect of dehydration and self-stip.Yet because the ring that moves about is under free state, to contact with the blade of screw shaft, contact area is minimum, stress concentration, and this just makes spiral shaft vane very big with the frictional dissipation of the ring that moves about, thereby greatly reduces the work-ing life of the screw shaft and the ring that moves about.
Summary of the invention
The purpose of the utility model is to propose a kind of novel folded spiral shell formula water extracter, existing folded spiral shell formula sludge dewatering equipment screw shaft structure improved, so that folded spiral shell formula sludge dewatering equipment structure is more reasonable, and longer service life.
The folded spiral shell formula sludge dewatering equipment that is used for sludge dewatering that the utility model proposes; Inlay a removable shirt rim along the limit, outer of spiral shaft vane; This shirt rim adopts high-abrasive material to process; The shirt rim width is greater than the width on limit, former spiral shaft vane outer, and has a groove on the end face of shirt rim, is lined with solid-state lubricating substance in the groove.
The folded spiral shell formula sludge dewatering equipment that the utility model proposes; Advantage is that in the shirt rim that inlay on limit, spiral shaft vane outer, width is bigger than former screw shaft outer hem width degree; Increased the contact area of screw shaft with the ring internal diameter that moves about; Reduced frictional force between the two, be lined with solid-state lubricating substance in the groove, along with the rotation of screw shaft the discharging the lubricating screw axle and move about the ring workplace of trace gradually; The workplace Castor Oil of screw shaft and the ring that moves about has reduced the workplace frictional coefficient, running resistance of screw shaft and the ring that moves about, has prolonged replacement cycle of the screw shaft and the ring that moves about significantly.And after the wearing and tearing of screw shaft shirt rim, need not to change whole screw shaft, the shirt rim replacing that only needs to inlay gets final product, and makes the running cost and the maintenance cost of the novel folded spiral shell formula water extracter after improving significantly reduce.

Among Fig. 1～Fig. 4,1 screw shaft, the 2nd, spiral shaft vane, the 3rd, wear-resisting shirt rim, the 4th, shirt rim groove, the 5th, the ring, the 6th that moves about, set collar.
Embodiment:
The folded spiral shell formula sludge dewatering equipment that is used for sludge dewatering that the utility model proposes is inlayed a wear-resisting shirt rim 3 on the limit, blade outer of screw shaft as shown in Figures 2 and 3, and these wear-resisting shirt rim 3 width are greater than the width on limit, spiral shaft vane 2 outer.In the middle of wear-resisting shirt rim 3, have a shirt rim groove 4, the solid lubrication material is housed in the shirt rim groove 4.
The workflow and the principle of work of the utility model are following: by Fig. 3 and shown in Figure 4, flocculation back sewage gets in the filtering chamber from the water-in of folded spiral shell formula sludge dewatering equipment.Screw shaft in the filtering chamber is rotated by electric motor driving, and the ring 5 that moves about that is applied on the spiral shaft vane also rotates thereupon, and clear water leaches through the slit of moving about between ring 5 and the set collar 6.In this process; Be embedded in the wear-resisting shirt rim 3 on the limit, screw shaft outer; Increase spiral shaft vane limit, 2 outer and moved about the contact area of ring between 5 internal diameters; Reduced frictional stress, and the solid lubrication material in the shirt rim groove 4 is along with micro-gradually the discharging lubricating screw axle 1 and move about ring 5 workplaces of the rotation of screw shaft 1.
