The lower end port of the sand conveying pipe is opposite to a sand collecting port of a compressed air nozzle, and the middle lower part of the sand conveying pipe is connected with a canopy hood. A water inlet pipe is arranged on the canopy hood. A clean water chamber is arranged above a sand filtering layer, and a distributing chamber is arranged below the canopy hood. The upper end port of the sand conveying pipe enters a sand washing device. The center of the sand washing device is provided with a separating cavity, and the center of the separating cavity is provided with a sewage cavity. The lower end port of the sewage cavity is sheathed on the sand conveying pipe to form a sand washing cavity. A draining groove which is connected with a drain pipe is arranged between the sewage cavity and the sand washing device. The clean water chamber is provided with a water collecting groove along the inner wall of the filtering container, and the water collecting groove is connected with a water outlet pipe.
Description
The utility model relates to a kind of water filtration treating apparatus.
Existing water filtration treating apparatus, the method for operation as various filter tanks, filter etc. all adopt filtration and filter sand backwash periodically to replace for guaranteeing the backwash of big intensity, needs the clear water deposit of big volume or provides the backwash water by other many lattice filter tank; When filtered water contained colloid and organic matter, it is clean fully that filter sand only depends on washing to be difficult to, if increase the compressed air washed-out sand, because its high-strength in short-term backwash needs, the pneumatic plant that is equipped with is on a grand scale, and utilization rate is then lower.Existing water filtration treating apparatus, as various filter tanks, filter etc., its filter sand backwash is constant intensity, can't adjust, and is difficult to adapt to the variation of building up back filtered water water quality.
The purpose of this utility model provides a kind of circulation washed-out sand Continuous Flow filter, saves huge filter sand backwash system, reduces the filter volume, realizes continuous filtration, uninterruptedly produces water.
The technical scheme of the utility model circulation washed-out sand Continuous Flow filter: it comprises sand filter blanket, the water inlet pipe that links to each other with chamber wall, outlet pipe in filtering container, the container, it is characterized in that:
The center of filtering container vertically is equipped with a sediment transport pipe, and lower port of sand delivering pipe is a sand collecting port, and sand collecting port is facing to compressed-air atomizer;
Sediment transport pipe middle and lower part connects a umbrella hood with one heart, and water inlet pipe penetrates and place on the umbrella hood from chamber wall;
Be clean water chamber above the sand filter blanket, the filtering container bottom is dirty sand chamber.
Sediment transport pipe upper port enters funnelform sand-washing device, the sand-washing device top is higher than clean water chamber, the center is the tubulose disengagement chamber, in the middle of the sand-washing device is concentric soil chamber, the soil chamber top is lower than the clean water chamber horizontal plane, the soil chamber lower port is funnel-form and is enclosed within outside the sediment transport pipe, become the washed-out sand chamber, between soil chamber and sand-washing device outer wall is rhone, the rhone drainpipe outer with leading to the filtering container wall is connected, clean water chamber is equipped with water leg along filtering container inwall ring-type, and the water leg outlet pipe outer with leading to chamber wall is connected.
The sand collecting port of above-mentioned lower port of sand delivering pipe is the Taper Pipe shape.
Above-mentioned filtering container top has regulates sand-washing device washed-out sand adjuster up and down.
The washed-out sand adjuster can be to regulate bolt.
The course of work of the present utility model: water is entered by after umbrella hood 2 even the distributions by water inlet pipe 1 before the filter, flows into clean water chambers 4 by sand filter blanket 3; Import outlet pipe 6 by water leg 5 and discharge, realize filtering; The dirty sand of sand filter blanket 3 bottoms slips into dirty sand chamber 7 downwards, compressed air from nozzle 8 blow to sand collecting port 9 carry dirty sand through sediment transport pipe 10 rise to make sand, gas, moisture from disengagement chamber 11; After realizing that in disengagement chamber 11 air cleans, filter sand slips into washed-out sand chamber 12 downwards, clear water upwards flows into washed-out sand chamber 12 and cleans the filter sand of whereabouts under pressure reduction h effect, washed-out sand sewage is discharged through soil chamber 13, rhone 14 and drainpipe 15, filter sand after cleaning falls back to filter sand layer 3, realizes the continuous wash of filter sand.According to filtered water water quality situation, adjust adjuster 16 to adjust washed-out sand intensity.
Advantage of the present utility model: utilize principles of fluid mechanics to realize the operation of automatic continous-stable fully, need not on dutyly, need not switch valve; Realize continuous filtration, uninterruptedly produce water with wash cycles filter sand filter sand mode; Compare with the periodicity backwashing filter, it is about 20% to reduce the filter volume, reduces the engineering equipment head and takes up an area of about 20%; Adopt the compressed air washed-out sand, can guarantee the washed-out sand effect, compare with the periodicity backwashing filter, its installation scale can reduce about 60%; After completing for use, can adjust the filter sand back washing strength, make filter can keep operational effect and adaptive capacity preferably according to the filtered water change of water quality.Be applicable to the purification filtering of running water, also can be used for the filtration treatment of sewage; The simplification of new construction and original engineering is transformed with being suitable for.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, circulation washed-out sand Continuous Flow filter comprises sand filter blanket, the water inlet pipe that links to each other with chamber wall, the outlet pipe in filtering container, the container, it is characterized in that:
The center of filtering container vertically is equipped with a sediment transport pipe 10, and lower port of sand delivering pipe is a sand collecting port 9, and sand collecting port is facing to compressed-air atomizer 8, and the sand collecting port of lower port of sand delivering pipe is the Taper Pipe shape.
Sediment transport pipe middle and lower part connects a umbrella hood 2 with one heart, and water inlet pipe 1 inherent filtration chamber wall penetrates and places on the umbrella hood.
Be clean water chamber 4 above the sand filter blanket 3, the filtering container bottom is dirty sand chamber 7, is distribution cavity under the umbrella hood.
