Abstract
The utility model provides a spiral sand-water separator, comprising: the device comprises a water tank, a U-shaped conveying groove, shaftless spiral blades and a driving device; the U-shaped conveying groove is obliquely arranged in a manner that the left part is low and the right part is high; the shaftless helical blade is arranged in the U-shaped conveying groove, the lower section of the shaftless helical blade is positioned in the water tank, and the upper end of the shaftless helical blade is connected with the driving device; the inner side of the shaftless helical blade is provided with a concentric column, and the diameter of the inscribed cylinder of the shaftless helical blade is larger than that of the concentric column. This spiral sand-water separator is less than shaftless helical blade inscription cylindrical concentric column through setting up the diameter, forms the passageway of relative less width between shaftless helical blade's inner wall and the outer cylinder wall of concentric column, can reduce and block up the risk, can prevent effectively again that the grit from falling back, helps improving sand-water separator's treatment effeciency.
Description
Technical Field
The utility model relates to the technical field of sand-water separation, in particular to a spiral sand-water separator.
Background
The spiral sand-water separator is used for separating sand and other various granular solid matters with larger specific gravity in the sand-containing sewage.
In order to reduce the blocking risk of materials, a shaftless helical blade is generally adopted in the prior sand-water separator. In practice, however, a part of the sand often falls back from the inner hole of the shaftless spiral blade to lower the treatment efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model provides a spiral sand-water separator which can effectively prevent sand from falling back.
Specifically, the utility model adopts the following technical scheme:
a spiral sand-water separator comprising: the device comprises a water tank, a U-shaped conveying groove, shaftless spiral blades and a driving device;
the U-shaped conveying groove is obliquely arranged in a manner that the left part is low and the right part is high;
the shaftless helical blade is arranged in the U-shaped conveying groove, the lower section of the shaftless helical blade is positioned in the water tank, and the upper end of the shaftless helical blade is connected with the driving device;
the inner side of the shaftless helical blade is provided with a concentric column, and the diameter of the inscribed cylinder of the shaftless helical blade is larger than that of the concentric column.
In order to effectively reduce sand fall back, the diameter of the inscribed cylinder of the shaftless helical blade preferably differs from the diameter of the concentric cylinder by no more than 5 mm.
In order to effectively reduce the risk of blockage, the diameter of the inscribed cylinder of the shaftless helical blade is preferably not less than 1mm different from the diameter of the concentric cylinder.
Preferably, in the spiral sand-water separator, the shaftless spiral blade is in a spiral rising shape, and the spiral rising angle is 15-30 degrees.
Preferably, in the spiral sand-water separator, a side plate is fixedly connected to the upper end of the shaftless spiral blade, and the middle of the outer side surface of the side plate is fixed to a rotating shaft of the driving device and rotates coaxially with the rotating shaft.
According to the spiral sand-water separator provided by the utility model, the concentric column with the diameter smaller than that of the inscribed cylinder of the shaftless spiral blade is arranged, and the channel with relatively small width is formed between the inner wall of the shaftless spiral blade and the outer cylindrical wall of the concentric column, so that the blocking risk can be reduced, sand and stone can be effectively prevented from falling back, and the treatment efficiency of the sand-water separator can be improved.
