Detailed description of the invention
See accompanying drawing, a kind of closed Continuous Flow sand filter, includes filtering tank 1 and washed-out sand tank 4, and the bottom of filtering tank 1 is pyramidal structure, and washed-out sand tank 4 is fixed on the top of filtering tank 1, and the bottom of filtering tank 1 is provided with sand export, and the top of washed-out sand tank 4 is provided with sand inlet, tubular filter sand sieve 3 is provided with in washed-out sand tank 4, the bottom of tubular filter sand sieve 3 is pyramidal structure, the top of tubular filter sand sieve 3 is fixed with point abrasive cone 6 in the below of sand inlet, the bottom of tubular filter sand sieve 3 is provided with sand removing hole and is connected with the sediment outflow pipe 17 leading to filtering tank 1 inside, the bottom of washed-out sand tank 4 is provided with the sewage draining exit of extraction and is connected with blow-off pipe 15, the sidewall of washed-out sand tank 4 is provided with delivery port 2 and is connected with outlet pipe 17, the front end of outlet pipe 17 be connected with in turn circulating pump 13 and jet send sand device 12 after and sand export be compiled in a place, and be connected with lead to sand inlet send sandpipe 8, bottom in filtering tank 1 is provided with the water-locator 14 of upwards spraying water, water-locator 14 is connected with the source water water inlet pipe 10 of extraction, the below of the inherent water-locator of filtering tank 1 14 is provided with conical sand arranging device 11, have the gap passed through for sand between the outer, bottom of conical sand arranging device 11 and the inwall of filtering tank 1 bottom pyramidal structure, the side at filtering tank 1 top is provided with source water delivery port and connects active water outlet pipe 16.
In the utility model, the top of washed-out sand tank 4 is provided with exhaust outlet and is provided with air bleeding valve 7, and the air produced in washed-out sand tank 4 is discharged by air bleeding valve 7; Bottom in washed-out sand tank 4 is the accumulated filth cavity 18 of half cone-shaped and draws, and sewage draining exit is positioned at the bottom of the accumulated filth cavity 18 of half cone-shaped; Send in sandpipe 8 and observation tube 9 is installed, to facilitate observation; In blow-off pipe 15, control valve is installed; In source water outlet pipe 16, control valve is installed; Filtering tank 1 is fixedly mounted on and is fixed on ground support.
Below in conjunction with accompanying drawing, the utility model is further described:
Source water flows into water-locator 14 by source water water inlet pipe 10, source water is sent in filtering tank 1 from bottom to top by the water distribution method of uniform plane by water-locator 14, impurity in the water of source and suspension retain absorption through quartz sand 5, namely filter source water, and the source water after filtration upwards flows out through source water outlet pipe 16, after quartz sand 5 retains impurity in the water of absorption source and suspension, along the inwall of filtering tank 1 bottom pyramidal structure and the surface uniform of conical sand arranging device 11 descending, clearance control flow between the outer, bottom of conical sand arranging device 11 and the inwall of filtering tank 1 bottom pyramidal structure, after the sand export of outflow filter tank 1 bottom, the rinse water sent into circulating pump 13 mixes, sand device 12(is sent to send sand to be fluidic by jet again, produce negative pressure, take away sand) spray feeding and send sandpipe 8, quartz sand 5 and rinse water are sending collision friction cleaning in sandpipe 8, and the sand inlet through washed-out sand tank 4 top is sent in washed-out sand tank 4.
Quartz sand 5 and the rinse water screen cloth surrounding again through dividing abrasive cone 6 to be distributed to tubular filter sand sieve 3 is carried out secondary cleaning and is separated, because the central vertical of point abrasive cone 6 is in the entrance center sending sandpipe 8, the quartz sand 5 entered and rinse water are scattered along the conical surface of point abrasive cone 6 and are flowed in tubular filter sand sieve 3, sieve the sand removing hole of 3 bottoms and sediment outflow pipe 17 to flow in filtering tank 1 filtered source water again after quartz sand 5 is blocked by the sieve wall of tubular filter sand sieve 3 through tubular filter sand; Impurity and suspension follow current through tubular filter sand sieve 3 sieve aperture flow in accumulated filth cavity 18, because the capacity of washed-out sand tank 4 inner chamber and sectional area are comparatively large, the flow velocity of current is slack-off, and impurity and suspension sink in accumulated filth cavity 18, after precipitation accumulation, discharge through blow-off pipe 15; Rinse water is then through the sieve wall of tubular filter sand sieve 3, send into circulating pump 13 through delivery port 2 and outlet pipe 17 to recycle, rinse water is sent into jet and is sent sand device 12 by circulating pump 13, again mixes with the quartz sand 5 sent into, and by giving sandpipe 8 to send into washed-out sand tank 4, circulate and so forth.
In the utility model, jet send sand device 12 to be made up of sandpipe a and recirculated water shower nozzle b, and rinse water is sent into shower nozzle b and sprayed by water circulating pump 13, generation negative pressure around shower nozzle b, thus is sent in sandpipe 8 by the quartz sand 5 fallen in sandpipe a.
