The self-cleaning quick sand filter comprises a barrel of which the upper part is of a cylindrical shape and the lower part is of a conical shape; a filter device is arranged at the middle and lower part of the barrel; a filter material cleaning device is arranged at the upper part of the barrel; a filter material lifting device is connected with a sand collecting box of the filter device and a sand washing pipe of the filter material cleaning device; the self-cleaning quick sand filter also comprises a filter material distributor; and the filter material distributor is of an umbrella shape and is arranged below the filter material cleaning device. According to the self-cleaning quick sand filter, the umbrella filter material distributer is arranged below the filter material cleaning device; and the filter material is evenly scattered in the filter layer through the filter material distributor after being cleaned. Therefore, the intermediate accumulation is avoided; the circulating filter effect is effectively improved; a discharge hole is arranged on the filter material distributor; the filter material uniformity is improved; and the diameter of the discharge hole is gradually increased outwards, so as to further improve the uniform effect. The self-cleaning quick sand filter is simple to operate, and improves the filter efficiency.
Description
Technical field
The utility model relates to the water filtration treatment facility, relates in particular to the water filtration treatment facility with filtering material cleaning device.
Background technology
At present; quartz filter be use wider filter plant in water treatment, to have an outlet effect good; the advantage that floor space is little is if but also ubiquity needs regularly to shut down that backwash, the untimely quartz sand of complicated operation backwash are hardened, more grow the problems such as the water effect is poorer running time.Simultaneously, appearance along with full-automatic filter, with raw water filtration and two relatively independent processes of carrying out simultaneously that are integrated into of filtrate cleaning and regeneration, but the problem that often occurs is: after filtrate cleans, filtrate is reapposed in the process of cylindrical shell, the phenomenon that in the middle of often occurring, filtrate is piled up is unfavorable for the filtrate tiling, cause the filtrate poor fluidity of both sides, thereby reduced the effect that whole system is filtered.
The utility model content
The utility model provides a kind of filtrate self-cleaning function that has for above problem, effectively prevents the Self-cleaning shifting sand filter of filter course middle part filtrate accumulation.
The technical solution of the utility model is: comprise that top is cylindrical and the bottom is the cylindrical shell of taper, filter is positioned at cylindrical shell middle and lower part, filtering material cleaning device and is positioned at cylindrical shell top, and the filtrate lifting device connects the silt box of filter and the sand developing tube of filtering material cleaning device; Also comprise the filtrate distributor, described filtrate distributor is umbrella, and is positioned at the below of described filtering material cleaning device.
The surface of described filtrate distributor is laid with discharge opening.
It is large that the diameter of described discharge opening becomes from inside to outside gradually.
Described filter comprises the former water water inlet pipe that radial distribution is housed on the ring sparger with raw water inlet that is positioned at filter bottom, former water water inlet pipe is connected to the guiding gutter below the interior taper water-locator of cylindrical shell, the water-locator top is the sand filter course, sand separator and silt box are equipped with in the bottom, and downflow weir and clear water output are equipped with in the cylindrical shell top.
Described filtering material cleaning device comprises the three phase separator that is positioned at the sand developing tube periphery, the washed-out sand mud discharging mouth, and sand-washing device is equipped with in the sand developing tube bottom.
Described filtrate lifting device comprises the sediment transport pipe of the gas that connects on the carrying sand pump and being connected the top sand developing tube of silt box, sand, water inlet.
The operation principle of this filter and process are: the use of Self-cleaning shifting sand filter can be divided into raw water filtration and two relatively independent processes of carrying out simultaneously again of filtrate cleaning and regeneration.Both complete at the diverse location of same filter.
Raw water filtration: pumped into the ring sparger of filter bottom when former water by head tank gravity flow or elevator pump, through guiding gutter and the even adverse current process filtering layer gradually that makes progress of conical distributor, impurity in former water is constantly held back, absorption, final filtrate is completed filter process from the excessive weir flow discharging of filter top.
The cleaning of sand and regeneration: when filtering when constantly carrying out, the impurity in former water is also constantly accumulated and is trapped in filter material surface, and the dirty amount of filter maximum be the sand of bottom.The sand of bottom is carried sand pump by the compressed air that is located at filter bottom and at first this part sand is quantitatively submitted in three-phase (water, gas and sand) separator to the top by the sediment transport pipe in batches, air venting, water enters in the sand-washing device that is connected with sand again and cleans, washed-out sand water is by independent discharge of pipes, the sand of wash clean is scattered again and is distributed to whole filter bed surface, has realized the cleaning of sand and the process that circulates.
by the sand of suspended solid pollutant, the passage that sand separator by taper and the inclined plane of filter form, arrive down silt box, then be transported in the sand-washing device of top rinse bath by carrying sand pump, sand in lifting process due to air, water, sand is acutely friction under compressed-air actuated effect, the foreign material wash-out that sand is held back, at three phase separator Air and sand, moisture from, sand flows in labyrinth passage because of the bottom of gravity by sand-washing device, the filtered water on filter bed top is by cleaning water pipe, bottom by decontaminating apparatus enters labyrinth passage, washing water flows in passage from the bottom up, the sand slow decreasing, both contact relatively, sand is cleaned.Clean sand is evenly distributed to filter bed central authorities again.Draining after cleaning is discharged by drainage arrangement.Clean displacement can by the regulating weir of up-down adjustment drainage arrangement, make it reach most suitable amount.
The utility model is provided with the filtrate distributor of umbrella below filtering material cleaning device, after filtrate cleans, be scattering into uniformly in filter course by the filtrate distributor, avoids the generation of middle packing phenomenon, effectively raises the effect of circulating filtration; Offer discharge opening on the filtrate distributor, improved the filtrate uniformity; It is large that the discharge opening diameter outwards becomes gradually, further promotes uniform effect.The utility model is simple to operate, has improved the efficient of filtering.
