Description
Affiliated technical field
The utility model belongs to the water filtration treatment facility, particularly has the water filtration treatment facility of filtering material cleaning device.
Background technology
At present; the quartz sand filtration device be in water treatment, use wider filter plant, to have a water outlet effective; the advantage that floor space is little; if but also ubiquity needs regularly to shut down that backwash, the untimely quartz sand of complicated operation backwash are hardened, grow problems such as the water effect is poor more running time more; CN2740597 discloses a kind of coagulation formula continuous self-cleaning and has washed filter; this filter has realized that the filtrate self-cleaning has that floor space is little, small investment, advantage that efficient is high, but filtrate lifting device and cleaning device efficient are not high enough.
Summary of the invention
The purpose of this utility model provides a kind of novel technical scheme with self-cleaning drift sand filter of filtrate self-cleaning function.
The technical solution of the utility model is, a kind of self-cleaning running sand filtration device, comprise that the top cylindrical lower portion is the cylindrical shell of taper, its structure is: filter is positioned at the cylindrical shell middle and lower part, filtering material cleaning device is positioned at cylindrical shell top, and the filtrate lifting device connects the silt container of filter and the sand developing tube of filtering material cleaning device.
Described filter comprises, be positioned at the former water water inlet arm that radial distribution is housed on the ring sparger that has raw water inlet of filter bottom, former water water inlet arm is linked the guiding gutter of the taper water-locator below in the 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, water level is regulated plate, the washed-out sand device of being made up of urceolus and inner core is equipped with in the sand developing tube bottom, idle loop and washed-out sand ring are alternately installed in the urceolus inboard, there is ring in the inner core outside, and the washed-out sand ring and the inner core of urceolus intersect, and are labyrinth passage between the inner/outer tube.
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 material that described washed-out sand device urceolus is stainless steel, inner core and washed-out sand ring is a polyurethane, and the material of idle loop is a stainless steel.
Also comprise general control system, described general control system comprises filtration resistance sensing device, the liquid level sensing device that is positioned at the cylindrical shell top, the central controller, the volume control device that is positioned at intake-outlet that are positioned at sand filter course bottom, is positioned at the control device of carrying sand pump.
The operation principle of this filter and process are: the use of self-cleaning running sand filtration device can be divided into raw water filtration and two relatively independent processes of carrying out simultaneously again of filtrate cleaning and regeneration.The two is finished at the diverse location of same filter.
Raw water filtration: the ring sparger that pumps into 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 the former water is constantly held back, absorption, final filtrate is finished 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 the 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.Drag losses according to the sand of bottom, transmit signals to control system, the compressed air that control system control is located at filter bottom is carried sand pump and at first this part sand is quantitatively submitted in three-phase (water, gas and the sand) separator to the top by the sediment transport pipe in batches, the air discharging, water enters in the sand-washing device that links to each other with sand again and cleans, washed-out sand water is by independent discharge of pipes, and 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.
The sand that is polluted by suspension, the passage that the sand separator by taper and the inclined plane of filter form, arrive silt box down, then by carrying in the washed-out sand device that sand pump is transported to the top rinse bath, sand in lifting process because air, water, sand is acutely friction under compressed-air actuated effect, the foreign material wash-out that sand is held back, air and sand in three phase separator, moisture from, sand then flows in the labyrinth passage because of the bottom of gravity by the washed-out sand device, and the filtered water on filter bed top is by cleaning water pipe, enters labyrinth passage by the bottom of decontaminating apparatus, cleaning water flows in passage from the bottom up, sand slowly descends, and both contact relatively, and 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 make it reach only amount by the regulating weir of up-down adjustment drainage arrangement.
The self-cleaning running sand filtration device of the high efficiency smart that the utility model provides can move in 24 hours continuously, need not shut down backwash and corresponding apparatus; System architecture and configuration are simple, removable, design, easy for installation; Simple to operate again because of no auxiliary element, can realize unattendedly, maintenance work is few; The backwash water yield is low, only be about 5% of the processing water yield, and the traditional type filter is about 20%; The casting bed of this machine is a thermopnore, so therefore the worry of no filter sand caking need not change sand.
