Specific embodiment
To make technical scheme and advantage clearer, below in conjunction with accompanying drawing embodiment of the present invention is made into
One step ground is described in detail.
First aspect present invention provides a kind of sandstone-filter screen integrated form irrigation filter, for carrying out to initial irrigation water
Filter, referring to Fig. 1 and Fig. 2, the irrigation filter includes：
Upper body 1, the upper body 1 is hollow housing, and the upper body 1 is internally provided with the first filtrate
Area 101, the first filtrate area 101 is used to load filtrate；Water inlet 102, the water inlet are provided with the upper body 1
102 are located at the top of the first filtrate area 101, for making the initial irrigation water enter the irrigation filter；
Lower case 4, the lower case 4 is hollow housing, and the lower case 4 is internally provided with the second filtrate
Area 401 and filter screen fixed component 6, the second filtrate area 401 is used to load filtrate, and the filter screen fixed component 6 is used for solid
Determine filter screen；The second filtrate area 401 is located at the top of the filter screen fixed component 6；The second filtrate area 401 and described first
Filtrate area 101 connects；Outlet 402 is provided with the lower case 4, the outlet 402 is located at the filter screen fixed part
The lower section of part 6, for the irrigation water after filtration to be exported from the irrigation filter；
Housing coupling part part 2, the housing coupling part part 2 is located at the outer surface of the upper body 1 and the bottom
The outer surface of housing 4, for the upper body 1 and lower case 4 to be linked together.
The operation principle of the irrigation filter of the embodiment of the present invention is：Filter screen 7 is fixed with filter screen fixed component 6, will be filtered
Material 5 is seated in the first filtrate area 101 and the second filtrate area 401, using housing coupling part part 2 by upper body 1 and lower case 4
It is fixed.Then water inlet 102 is connected with irrigation water back with water inlet line in irrigation system, outlet 402 and irrigation system is irrigated
Water water outlet pipeline is connected.Initial irrigation water enters the irrigation filter by water inlet 101, through media filtration and filter screen mistake
Gained irrigation water is exported by outlet 402 after filter, and farmland is irrigated.
Irrigation filter provided in an embodiment of the present invention becomes one traditional sandrock filter and well strainer,
The function of two kinds of filters is gathered together.Due to the design using integration, the volume of the irrigation filter is reduced,
Simultaneously cost is reduced, and be easily installed.

1 and lower case 4 be processed into an entirety, then flange is connected using bolt 3.
In above-mentioned irrigation filter, being preferably sized to of the first filtrate area 101 accounts for the volume of the upper body 1
More than 1/2, so ensure that filling filtrate amount meet filter requirement.
In above-mentioned irrigation filter, it is seated in first filler 501 in the first filtrate area 101 and is seated in the second filtrate area
401 the second filtrate 502 can select the filtrate of same particle size, it is also possible to select the filtrate of different-grain diameter, realize gradient filtration,
Improve filter effect.Filtrate 5 is not limited only to sandstone filtrate, can be arbitrary filtrate commonly used in the art.Filtrate 5 it is concrete
Species should be determined according to the water quality of actual irrigation water.
In above-mentioned irrigation filter, the concrete species of filter screen 7, also without strict restriction, can be commonly used in the art
Arbitrary filter screen.The aperture of filter screen 7 should be less than the particle diameter of the second filtrate 502, to prevent filtrate from spilling.Filter screen 7 can be one
Metafiltration net, or multistorey strainer mesh are used cooperatively.
Above-mentioned irrigation filter can be manufactured using plastic processing, to mitigate weight, reduces cost.For example can be poly-
Vinyl plastics, igelite, polypropylene plastics etc..
Second aspect present invention provides a kind of irrigation filtration system of the irrigation filter of utilization first aspect present invention, institute
