The utility model content
To the above-mentioned defective that exists in the prior art, the purpose of the utility model has provided a kind of modified water treatment sand filter that improves effluent characteristics, stable and reliable operation.
The technical scheme of the utility model; Comprise: contain the cylindrical shell 1 of inner chamber, the delivery port 2 that communicates with cylinder lumen is arranged at cylindrical shell 1 bottom, and delivery port 2 connects outlet pipe 3; At least be provided with the two-stage layer of sand 4 that grit size is gradually little successively from the bottom to top in the inner chamber of cylindrical shell 1; The tubular type water inlet water-locator 5 that the layer of sand of bottom below has supporting layer 4a, the top of layer of sand 4 to be provided with to communicate with water inlet pipe has backwash discharge outlet 6 on the barrel wall of layer of sand 4 tops;
Improved structure is; Said cylindrical shell 1 intracavity bottom is provided with the spill convex structure drainage member 7 of some through holes; Said spill convex structure drainage member 7 is positioned at the below of supporting layer 4a; Between said spill convex structure drainage member 7 and cylindrical shell 1 diapire paring chamber 8 is arranged, the top of said outlet pipe 3 connects backwash water inlet pipe 9.
The technique effect of the utility model is:
1, because cylindrical shell 1 intracavity bottom is provided with the spill convex structure drainage member 7 of some through holes; And between spill convex structure drainage member 7 and the cylindrical shell 1 inner chamber diapire paring chamber 8 is arranged, current can be flowed in the paring chamber 8 through the through hole of spill convex structure drainage member 7 corresponding sites, flow into outlet pipe by delivery port then; With the prior art ratio; Eliminate the current dead angle, had the unimpeded characteristics of water stream channel, can improve effluent characteristics;
2, be connected on the outlet pipe 3 owing to backwash water inlet pipe 9; And cylindrical shell 1 intracavity bottom is provided with the spill convex structure drainage member 7 of some through holes, and is provided with corresponding paring chamber 8, during backwash; Backwashing water gets into paring chamber 8 by delivery port 3; Because drainage member 7 is the concavity arc-shaped structure, paring chamber 8 has the effect that distributes current with respect to the through hole on the spill convex structure drainage member 7, therefore; The backwashing water that gets in the paring chamber 8 can carry out backwash via 7 pairs of supporting layers of concavity arc-shaped structure drainage member and all layers of sand more equably, can improve filter effect and the normal operation that helps sand filter.And backwash water inlet pipe 9 is connected on the outlet pipe 3, with prior art the backwash water-locator is located at the cylinder lumen ratio, have simple in structure be convenient to the characteristics of Maintenance and Repair.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
