Furthermore, the spiral conveying assembly is obliquely arranged, the discharge end of the spiral conveying assembly is higher than the feed end, when slurry moves from bottom to top, the slurry is influenced by gravity, moisture in the slurry moves downwards, and sand in the slurry moves upwards under the pushing of the spiral blades, so that the solid-liquid separation degree of the slurry is improved, and the water content in the sand is better reduced.
Furthermore, the cross section of the water collecting shell is arc-shaped, the water collecting shell is coaxially arranged outside the filtering window, the water collecting shell and the shell form a closed water collecting cavity, and the water outlet is formed in the lowest position of the water collecting cavity, so that clear water in the water collecting shell can be completely discharged. In addition, the height of the clear water overflow port limits that some clear water that can not be discharged from the clear water overflow port in the settling tank can be discharged from the water outlet.
The utility model discloses in still including enabling this other subassemblies that supply concrete waste water recycle device normal use, for example the rotatory driving motor of drive helical blade etc. all belong to the conventional selection in this field. In addition, the device or the assembly which is not limited in the utility model adopts the conventional means in the field, for example, the settling tank, the stone screen, the helical blade, the water screen and the like all adopt the conventional arrangement.
The utility model discloses a theory of operation:
pour into the gunbarrel with concrete production waste water from the waste water import, building stones in the waste water are sieved out and are discharged from the building stones export by the building stones screen cloth, other composition aggregations in the gunbarrel deposit a period of time, open clear water overflow mouth discharge some upper clear water again, then the screw conveyor subassembly begins work, with lower floor's thick liquids discharge gunbarrel, when thick liquids remove in the screw conveyor subassembly, moisture in the thick liquids oozes through the water strainer, the thick liquids become the sand material and discharge from the discharge gate of screw conveyor subassembly, the moisture that oozes in the thick liquids is discharged from its delivery port after collecting through the shell that catchments.
Compared with the prior art, the beneficial effects of the utility model are that:
this device can once only isolate building stones and sand material in the concrete production waste water and be used for recycle, has effectively improved the recycle ratio of each component in the concrete production waste water, has fine practicality.
