Description
Technical field the utility model relates to a kind of slight irrigation filter, specifically a kind of a kind of New-type Swirl Flow well strainer that the hydraulic cyclone filter is combined with well strainer.
The background technology slight irrigation comprises technology such as drip irrigation, microspray irrigation and infiltrating irrigation, and is because its water outlet device runner or aperture are less, higher to water quality requirement.Therefore, purification of water quality just becomes the key that micro irrigation technology is applied.At present both at home and abroad the filter that adopts mainly contains: husky formula filter, hydraulic cyclone filter, stacked and well strainer etc. are several.These filter major parts are to have a style of one's own, and are separated from each other.Only under the better situation of condition of water quality, stacked and well strainer can use separately.And in most of the cases, or cooperate in twos or three uses that cooperatively interact, learn from other's strong points to offset one's weaknesses.Reach the silt of different-grain diameter size in the water, the purpose of Impurity removal.But the way that this multistage filter matches and uses often causes pipeline many, and contact is many, has increased along the loss of the defeated water pressure of journey, and then has strengthened operating cost.Simultaneously, each filter is separate, each one-tenth system, separate unit cost height, the corresponding investment cost that increases irrigation system.In addition, common well strainer is because the restriction of design space and application target is general not from washing capacity, usually because the tiny silt of stopping attached on the filter screen, influences the operate as normal of well strainer.Need often unpick and wash, also increase no small workload.
China patent CN2349774Y disclosed " drip irrigation filter ", it is a kind of filter that whizzer and well strainer are combined as a whole, the deficiency of its existence is: the filter core of being made up of framework and filter screen is placed in the inner chamber of bucket, filter area reduces relatively, and eddy flow does not almost have from flushing action filter screen; The lower end of housing independently is provided with the desilting bucket, also must be provided with special flushing machine, the structure relative complex, and production cost is higher.
The summary of the invention the purpose of this utility model is to provide a kind of eddy flow well strainer simple in structure, reasonable in design, with low cost, it can finish centrifugal and net formula double-filtration simultaneously, and under cyclonic action, wash filter screen automatically and in real time, guarantee the good permeability of filter screen, and the filter screen long service life.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of eddy flow well strainer, comprise housing and top cover thereof, water inlet, delivery port and sand excluding valve, and top cover is provided with air bleeding valve, that the housing epimere is is cylindric, hypomere is the inverted round table shape, and its junction is provided with dividing plate; Water inlet is arranged on the top of rounding platform piece housing along the housing tangential direction, delivery port is positioned at the cylindrical section housing place of screen pack top, it is characterized in that the filter screen fixed head is connected with dividing plate, fall with one that round table-like porous filtering rack is unsettled to be fixed in the housing, the porous filtering rack covers filter screen outward, and the filter screen mouth is pressed between filter screen fixed head and the dividing plate; The below of screen pack is provided with branch hourglass bucket, and dividing the below of hourglass bucket is sand collecting cavity; The bottom of sand collecting cavity is provided with the inclined-plane base plate, and the lowest part of inclined-plane base plate is provided with sand excluding valve.
Between described screen pack and the water inlet semicircle is set or arc-shaped watertight shutter also claims deflector, water fender (or deflector) is fixed on the dividing plate place.
The passage that forms between described water fender and the housing presents by wide to narrow variation along water (flow) direction.
Described porous filtering rack can be welded into cylindric by stainless steel strip, also can be directly punches to form on the cylinder that metal or macromolecular material are made, and its mesh area is 0.5-5cm
2, shape can be circle, ellipse, prismatic, square, rectangle etc.
The eddy flow well strainer that manufactures and designs by technique scheme, when water enters the filter along the housing tangential direction from water inlet, rely on inertia to rotate along inner walls, under action of centrifugal force, the sand grain that quality is bigger in the water is got rid of to inner walls, and along the inner walls sedimentation, enters sand collecting cavity through a minute hourglass bucket, drop on the inclined-plane base plate, regularly discharge then from sand excluding valve; Through the water of cyclone filter, filter through the silt of filter screen again fine particle, send by delivery port at last.Because this eddy flow well strainer filters combination in a housing with rotational flow separation and net formula, has simplified the filter pipeline, thereby has reduced the water flow pressure loss, and reduced operating cost.Because current are centrifugal cyclone in the housing, cause housing center low-pressure area, can alleviate the water pressure of screen pack greatly, simultaneously, because the eddy flow direction is in the screen pack tangential direction, nature forms from flushing action the filter screen outside under the current turning effort, to guarantee that filter screen has good permeability in real time.Owing to be provided with semicircle or arc-shaped watertight shutter between its water inlet and the screen pack, when prolongation filter screen life-span, the speed-raising of performance water conservancy diversion, strengthening centrifugal separating effect, taken into account the increase area of filter net, improve the effect of filter efficiency.Owing to be provided with branch hourglass bucket and inclined-plane base plate in its housing, both helped the concentrated sedimentation of silt, the current that the silt that can avoid again depositing is rotated once more take up.
The utility model is described in further detail in conjunction with the accompanying drawings below by embodiment.
