The spiral-pile dehydrator structurally comprises a filtering main body formed by mutually laminating fixed rings and movable rings, wherein a spiral shaft penetrates through the filtering main body; in the working process, the full dehydration is realized through gravity concentration and the internal pressure effect of the back pressure plate on the sludge in the pushing process, the filtrate is discharged from the filter gap formed by the fixed ring and the movable ring, and the mud cake is discharged from the tail end of the dehydration part.
However, as the use of existing spiral shell dehydrators increases, the disadvantages of existing spiral shell dehydrators are gradually exposed, including:
1. the existing spiral shell hydroextractor is inconvenient to add flocculant in the use process, and the sufficient mixing of the flocculant and the sludge is difficult to realize.
2. The existing spiral shell dehydrator has structural defects, specifically, because the spiral shell dehydrator discharges filtrate by utilizing gravity and internal pressure in principle, in the spiral shell dehydrator, a filtering main body is obliquely arranged according to a fixed angle, however, the characteristics of fluidity, dehydration property and the like of different types of sludge are different, the requirements on the inclination angle of the filtering main body are different, namely the spiral shell dehydrator has poor universality, and the spiral shell dehydrator with different specifications is required to be selected for different types of sludge treatment; in addition, the activity adjustability of the lamination in the existing spiral shell hydroextractor is poor, and targeted adjustment can not be made according to the dewatering requirement.
3. The existing spiral shell stack dehydrator is easy to generate incomplete dehydration, specifically, the existing spiral shell stack dehydrator only performs dehydration once in the working process, and then the obtained mud cake is discharged from the tail end of the dehydration part, and the mud cake still contains more water with great probability.
