Description
Technical field
The present invention relates to agricultural machinery technical field, and in particular to a kind of backwash filter for drip irrigation system.
Background technology
Drip irrigation is that water is sent to crop root and entered by the aperture on diameter about 10mm hollow billets or water dropper using plastic conduit
Row localized irrigation.It is a kind of maximally effective Water Saving Irrigation Mode of current drought and water-scarce area, and the utilization rate of water is up to 95%.
Drip irrigation has higher water-saving and yield-increasing effect compared with sprinkling irrigation, while can combine fertilising, improves fertilizer efficiency more than one times.It is applicable to
Fruit tree, vegetables, industrial crops and warmhouse booth are irrigated, and field crop irrigation is can also be used in the place of drought and water shortage.
In arid area, agricultural irrigation is fetched water from subterranean well, and the more impurity of underground water, drip irrigation system is to water quality
Requirement it is stricter, general well water is needed by filtering, and otherwise the impurity in water can blocking dropping head.Existing drip irrigation system
Use thick, thin dual stage filter apparatus mostly, the general filtering that thick impurity is realized using centrifugal filter, thick impurity can by
Line is discharged in good time, it is not necessary to is shut down and is rinsed centrifugal filter；But the filter used for thin impurity can not be arranged online
It is dirty to carry out blowdown using artificial to dismantle filter core, it is necessary to shut down, delay irrigation time, operating efficiency is not also high.
The content of the invention
It is an object of the invention to provide a kind of without shutting down, can blowdown online the backwash filter for drip irrigation system
Device.
The purpose of the present invention is achieved through the following technical solutions：
A kind of backwash filter for drip irrigation system, including housing and the filtering net cylinder positioned at enclosure interior, it is described
Housing includes circular cylindrical shell and the cone cylinder housing positioned at circular cylindrical shell both ends, the open at one end of the filtering net cylinder and fixed company
It is connected in the cone cylinder shell inner surface of water inlet side, the other end of filtering net cylinder closes and is connected with blow-off pipe, and blow-off pipe passes through
The cone cylinder housing for passing mouth of a river side stretches to exterior space, in the filtering net cylinder at the cone cylinder housing of water inlet side
It is provided with current deflecting valve.
Further, the current deflecting valve is driven by rotating shaft and rotated, and is provided with handle in rotating shaft, rotating shaft runs through shell
Body and filtering net cylinder and both ends are arranged on the outer surface of housing.
Further, the housing uses quality carbon steel cylinder, and the filtering net cylinder uses double-layer stainless steel cylinder.
The beneficial effects of the present invention are：
Structure design compact and reasonable of the present invention, floor space is small, installs mobile flexible and equipment few easy workout part, nothing
Consumptive material, operation and maintenance cost is low, and operational administrative is simple；Meanwhile filtering accuracy of the present invention is high, filter area is big, has both kept high
Flow, there is the low pressure loss again；Easy to operate, cleaning is thoroughly, it is not necessary to which installation is bypassed to dismantle blowdown, without artificial
Carry out cleaning filter core；It is not required to shut down, is truly realized online blowdown.

Embodiment
The specific embodiment of the invention uses following technical scheme：
Referring to accompanying drawing 1 and accompanying drawing 2：
A kind of backwash filter for drip irrigation system, including housing 1 and the filtering net cylinder 2 inside housing 1,
The housing 1 includes circular cylindrical shell 101 and the cone cylinder housing 102 positioned at the both ends of circular cylindrical shell 101, and the one of the filtering net cylinder 2
End is opened wide and is fixedly connected on the inner surface of cone cylinder housing 102 of water inlet side, and the other end of filtering net cylinder 2 is closed and connected
Blow-off pipe 3 is connected to, cone cylinder housing 102 of the blow-off pipe 3 through delivery port side stretches to exterior space, leaned in the filtering net cylinder 2
Current deflecting valve 4 is provided with the cone cylinder housing 102 of nearly water inlet side.
Preferably, the current deflecting valve 4 is driven by rotating shaft 5 and rotated, and is provided with handle 6 in rotating shaft 5, rotating shaft 5 runs through
Housing 1 and filtering net cylinder 2 and both ends are arranged on the outer surface of housing 1.
Preferably, the housing 1 uses quality carbon steel cylinder, and the filtering net cylinder 2 uses double-layer stainless steel cylinder.
The operation principle of backwash filter：When backwash filter works, blow-off pipe 3 is closed, current deflecting valve 4
In opening, current enter backwash filter from entrance, and outlet is filled into by screen tube 2, tiny dirt in water
Impurity is intercepted by filtering net cylinder 2, when manometer detects that intake-outlet pressure difference reaches 0.05MPa, tackles filtering net cylinder 2
Cleaned, first manual-lock current deflecting valve 4, then open blow-off pipe 3, now, water is by the inflow of the outside of filtering net cylinder 2
Side, the dirt impurity on the inwall of washing and filtering net cylinder 2, is discharged through blow-off pipe 3, plays reverse automatically washing filter screen cylinder 2 and row
Dirty effect；Whole sewage backwash process does not have to closing system, without manually cleaning filter core is carried out, realizes online blowdown.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned reality
Example is applied, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for this technology
For the those of ordinary skill in field, some improvements and modifications without departing from the principles of the present invention, these are improved and profit
Decorations also should be regarded as protection scope of the present invention.
