Description
Technical field
The utility model relates to a kind of water purification filter, refers in particular to the filter that the water higher to sand content carries out purified treatment.
Background technology
Huanghe valley shortage of water resources, Water Consumption in Agriculture takies the 70-85% of the Yellow River total water consumption at present, and development efficient water-saving irrigation is the effective way alleviating water resource disparities between supply and demand.Higher based on Huanghe water sand content, in order to reach drip irrigation water standard, need to filter Huanghe water.Current have Huanghe water filtration common method: natural subsidence, sandstone filter, net formula is filtered.Natural subsidence Huanghe water is introduced the artificial setting pot of a constant volume, and under water flow slowly situation, the sand grains in Huanghe water and other impurity natural subsidence, realize the filtration to Huanghe water; It is as filter medium using the sandstone of certain particle diameter that sandstone filters, Huanghe water is by the sandstone of filter medium, sand grains and other impurity are intercepted at filter medium sandstone surface or absorption inside, filtered Huanghe water delivers to next link through filter medium sandstone, achieves the Separation of Solid and Liquid to Huanghe water; Net formula is filtered and is realized filtering using filter screen as filter medium, belongs to known category, no longer describes.Take natural sedimentation, the quantities of building pond is large, and land occupation area is large, invests larger.In addition, also limit by orographic condition, can not arrange suitablely; The long-pending sand of basin bottom and other impurity need cleaning within a certain period of time, and cleaning up cost is high.It is carry out work by pressure vessel that sandstone filters, the particularity of Huanghe water high sand content, and because pressure vessel is subject to holding quantitative limitation, cause frequent backwash, washing water quantity is large, makes process water efficiency not high; As the sandstone of filter medium, also there is space between sandstone, the surface area of sand grains increases, and under suction-operated, the organic matter in water is also blocked, and a large amount of nutrient in Huanghe water is filtered.Application number is the flusher that application discloses a kind of electric control self-cleaning strainer of 200810217079.8, be provided with water flow jet in addition to the device on fie screen inwall in the dirt sucking device assembly of filter, by suction nozzle to fie screen inwall inject high pressure current, the aforementioned various impurity being attached to fie screen inwall is washed away in advance, the means of row absorption carry out the backwash of filter again, to improve backwash effect.But, even if add backwashing equipment, first, adhesive force direction due to the various impurity of fie screen inwall is from inside to outside generally, with aforementioned High-Pressure Water to wash away direction consistent, therefore, still have part to be attached to the impurity of fie screen inwall, the impurity that especially adhesive force is stronger is difficult to thoroughly loosen in this kind of high pressure scour process and by suction, removing; Secondly, the fie screen outer wall in filter is in blind area in backwash process always, is positioned at the various attachments being attached to fie screen outer wall and is not removed all the time, frequently use backwash, can affect the filter efficiency of filter; In the former water system of low-pressure, the defect of this kind of Filter Back Washing aspect is never effectively solved.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Huanghe water filter being applicable to agricultural drop irrigation, this filter is that one can in filter process, continuous flushing filter screen is realized and can the Huanghe water filter that drip irrigation is applicable to of automatic sand draining under passive state, its floor space is little, arrange suitablely, effectively can tackle the silt particle in Huanghe water and impurity, not reduce the organic substance in Huanghe water, with traditional sandstone compared with well strainer, filter efficiency can be significantly improved.
The technical problems to be solved in the utility model is realized by following structure: a kind of Huanghe water filter being applicable to agricultural drop irrigation, comprise fixed mount, web plate, water distributor, long-pending sand launder, it is characterized in that: described a pair web plate and both sides are that the end face shrouding of wedge forms water storehouse, and a pair web plate upper end is fixed on fixed mount; Lower end is connected with base support by long-pending sand launder side plate, described a pair long-pending sand launder side plate and long-pending sand launder base plate are configured for the long-pending sand launder of long-pending sand effect, long-pending sand launder one end is connected with sediment outflow pipe, the fixed mount upper end crossbeam of described both sides connects, crossbeam is equipped with the liquid level sensor for monitoring water level, a pair water distributor is fixed on crossbeam two ends and is placed in inside described a pair web plate upper end.
The utility model also comprises following structure: described a pair web plate upper end is fixed on fixed mount with 15-30 ° of symmetry respectively.Described long-pending sand launder base plate is placed in the middle part of base support, in strip layout.The each arrangement of going to the bottom of described a pair water distributor has row's spurt hole, described spurt hole respectively with 15-30 ° with a pair web plate in opposite directions.Described end face shrouding is placed in fixed mount both sides.Described end face shrouding upper end is equipped with overfall, and lower end is equipped with sediment outflow pipe, and described sediment outflow Guan Yuji sand launder communicates.
Operation principle of the present utility model: Raw Water of Yellow River is pressurizeed by immersible pump, is split into two parts through water source tube, is ejected on web plate, permeates, Separation of Solid and Liquid by a pair water distributor through flow jeting port.Treated water permeation, to the outside of water storehouse, concentrates on the rear pond of concrete structure filter by guiding gutter.Be trapped within sandstone on a pair web plate inside water storehouse and other coarse granule impurity sprays and Action of Gravity Field downward motion at former water, be deposited in long-pending sand launder.When sandstone and granule foreign are piled up gradually, former water liquid level rises thereupon, when liquid level sensor detects liquid level to certain altitude threshold value, there is provided signal to control system, motor-driven valve is opened automatically, sediment outflow pipe communicates with atmospheric pressure, and the sandstone piled up at long-pending sand launder under former jet water stream and Action of Gravity Field and impurity are discharged to the downstream position relative to immersible pump of Hetao Irrigation District general main canal automatically from sediment outflow pipe.When the liquid level of water storehouse drops to certain position, liquid level sensor provides signal to control system, and sediment outflow pipe is closed by motor-driven valve.Concentrate on pond after the filter of concrete structure through the water of filtration treatment, enter next step agricultural irrigation link by water pump.
The utility model tool has the following advantages:
1, this filter bottom area is little, and after thus required concrete structure filter, pond floor space is little, and concrete structure civil engineering is little, economizes the land resource and material cost;
2, uninterrupted filtration continuously, do not stop by sediment outflow affects filtering, filtration treatment Huanghe water efficiency is high;
3, automatic sand draining, piles up without silt particle: can not pile up on the spot through Separation of Solid and Liquid silt particle out, automatically enter in Hetao Irrigation District general main canal, enter into field with trunk canal current;
4, duct type water-locator angle can regulate according to pressure;
5, Organic substance in water matter content can not be destroyed, reach agricultural drop irrigation water quality requirement;
