Description
Technical field
The present invention relates to a kind of movement that agricultural irrigation systems is filtered backwash net-type filter in turn.
Background technology
Current well strainer for agricultural irrigation systems generally adopts other clear water that filter monomer to carry out backwash to this filtration monomer, under the state of work, generally can not complete simultaneously filtration and the backwash of filter self.Although some well strainers self can finish the work simultaneously filtration and backwash under state are arranged, its filter and the effect of backwash not fine.And complex structure, complex operation, net formula filter core circumference unbalance stress easily causes the distortion of net formula filter core, increases operating cost.The disclosed a kind of automatic backwashing filter of patent CN 1421261A for example, include a shell body, which is provided with water inlet, delivery port and sewage draining exit, it is characterized in that in this shell body near water inlet end place's installing one valve shaft, this valve shaft first half installing one recoil valve plate, valve plate is filtered in Lower Half installing one, and two valve plate semicirculars in shape are mutually the cross vertical configuration and are fixed on valve shaft, filters the valve plate right side and arranges one
The filter medium of shape filter should
Establish a plurality of filter bores on the shape filter.Its weak point is that the filter screen of water inlet is in filtration condition all the time before the valve shaft of this filter, can not complete the backwash of whole filter screen, and be
Shape filter unbalance stress easily deforms, and increases system operation cost, complex structure, inconvenient operation.
Summary of the invention
The object of the invention is to solve under the normal filtration state, filter self can not be completed the backwash to whole filter screen simultaneously, and backwash situation lower filter screen discontinuity, causes the filter screen distortion, increases the problem of operating cost.And then provide a kind of in the situation that normal filtration can be completed alone the backwash of whole filter screen, and filter screen is stressed even, can not deform, and reduces operating cost, and simple in structure, safe and reliable movement is backwash net-type filter in turn.
basic system of the present invention mainly comprises housing, upper press cover, base, water inlet, delivery port, blow-off pipe and net formula filter core, the two ends that it is characterized in that housing are provided with upper press cover and base, the close upper press cover of housing outer wall place is provided with blow-off pipe, be connected with external force means by synchronized in the same way gear drive on upper press cover, the bottom of base is provided with delivery port, its outer wall is provided with water inlet, enclosure interior is provided with net formula filter core, the two ends of net formula filter core are socketed in " U " shape cushion rubber that is embedded in annular groove on upper press cover and base, be provided with machine annulus dividing plate between net formula filter core outer wall and inner walls, in the annulus dividing plate, be respectively equipped with annular groove on outer wall, be provided with large mechanically-sealing apparatus in annular groove, respectively with outer wall and the inner walls close proximity of net formula filter core, the annulus dividing plate can only be done on the outer wall of net formula filter core and pump, and annulus partition movement scope can not surpass near that end water inlet of annulus dividing plate or the tube wall of blow-off pipe.Its annulus dividing plate is provided with the power pull bar, and the power pull bar passes upper press cover, is provided with the gadget sealing device between them, and the power pull bar is connected with synchronized in the same way gear drive.
The present invention is provided with and makees the annulus dividing plate that pumps on net formula filter core, along with the movement of annulus dividing plate, can carry out backwash to the different part of net formula filter core, thereby under the state of normal filtration, complete the backwash of whole net formula filter core.In the process of backwash, net formula filter core is circumferential stressed, and is whole stressed even, is difficult for causing net formula filter core to deform, and reduced the destruction to filter screen, reduced cost, and overall structure is simple, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure, 1 is upper press cover, and 2 is housing, and 3 is the power pull bar, 4 is external force means, and 5 is gear drive, and 6 is " U " shape cushion rubber, 7 is net formula filter core, 8 is the gadget sealing device, and 9 is blow-off pipe, and 10 is water inlet, 11 is large mechanically-sealing apparatus, 12 is delivery port, and 13 is base, and 14 is the annulus dividing plate.
Specific embodiment
Fig. 1 is that the present invention moves the structural representation of backwash net-type filter embodiment in turn.the two ends of its middle shell 2 are provided with upper press cover 1 and base 13, the close upper press cover of housing outer wall place is provided with blow-off pipe 9, passing through in the same way on upper press cover, gear drive 5 is connected with external force means 4, the bottom of base is provided with delivery port 12, its outer wall is provided with water inlet 10, enclosure interior is provided with net formula filter core 7, the two ends of net formula filter core are socketed in " U " shape cushion rubber 6 that is embedded in annular groove on upper press cover and base, be provided with annulus dividing plate 14 between net formula filter core outer wall and inner walls, in the annulus dividing plate, be respectively equipped with annular groove on outer wall, be provided with large mechanically-sealing apparatus 11 in annular groove, respectively with outer wall and the inner walls close proximity of net formula filter core, the annulus dividing plate can only be done on the outer wall of net formula filter core and pump, and annulus partition movement scope can not surpass near that end water inlet of annulus dividing plate or the tube wall of blow-off pipe.Its annulus dividing plate is provided with power pull bar 3, and the power pull bar passes upper press cover, is provided with gadget sealing device 9 between them, and the power pull bar is connected with synchronized in the same way gear drive.
operation principle: under mobile backwash net-type filter normal operating conditions in turn, the annulus dividing plate is positioned at the top of net formula filter core under the effect of external force means, its annulus dividing plate makes blow-off pipe be in closed condition, sewage is in water inlet moves the housing of backwash net-type filter in turn, the filtration of net formula filter core is arranged again, clear water after it filters flows out through delivery port, constantly filtering simultaneously, some impurity just are attached to the outer surface of net formula filter core, net formula filter core inside and outside differential pressure constantly increases, after pressure reduction reaches certain numerical value, external force means starts, mobile backwash net-type filter in turn enters the backwash state, the normal filtration of its net formula filter core is also being carried out, external force means promotes the annulus dividing plate at the uniform velocity downwards by gear drive and power pull bar, blow-off pipe can be opened simultaneously, and the cavity between net formula filter core and housing is divided into two chambeies, up and down, this is that sewage enters through water inlet, enter annulus dividing plate second chamber, again by the filtration of net formula filter core, clear water after a part is filtered is flowed out by delivery port, another part clear water can be entered by net formula filter core first chamber of annulus dividing plate, thereby net formula filter core is carried out backwash from top to bottom, addle after backwash is discharged by blow-off pipe, when the annulus partition movement during to least significant end, water inlet is closed, this moment, external force means started counter motion, the annulus dividing plate moves from bottom to top by gear drive and power pull bar, again net formula filter-core back-flushing is washed, after moving to the top of net formula filter core, blow-off pipe cuts out, thereby complete the backwash to whole net formula filter core.
