Above description is only intended to clearly illustrate the application example, and is not to presently filed embodiment
Restriction.Guarantor of every technical solution changes and variations that derived from for belonging to the application still in the application
Protect the row of range.
The course of work of the application is as follows：As shown in figure 3, settling pit 31 is set in advance and stores irrigation water to be filtered,
The import of water inlet pipe 8 is located in settling pit 31 and is equipped with trash rack 36, preferably makes the pressure of the irrigation water to be filtered in water inlet pipe 8
Head is 0.2 to 0.5 meter, the filtering ponds 32 that setting is isolated with settling pit 31, and the application is mounted on 32 top of filtering ponds, mistake
Filter tank 32 be equipped with the outlet pipe 33 with valve, and outlet pipe 33 can be connected with the pipe-line system of water-saving irrigation realization water supply,
Pressure water pump 28 is mounted on the branch pipe of 32 bottom of filtering ponds or outlet pipe 33, before pressure water pump 28 is opened, in filtering ponds 32
A part of water pressure supply water pump 28 must be reserved to extract, pollution discharge pond 34, the position of pollution discharge pond 34 is arranged in the position of corresponding sewage draining exit 12
There are the return pipe 35 for taking back water screen 37, outlet and the 32 top phase of filtering ponds of return pipe 35 higher than filtering ponds 32 and its underpart
It is logical.When being filtered operation, first, controller makes the unlatching of inlet valve 29, decontamination valve 15 remain turned-off, while pressure water pump 28 opens
It moves, after the irrigation water to be filtered in settling pit 31 is by trash rack 36, left cone cylinder circle 4 and filtering net cylinder 1 is entered by water inlet pipe 8
It is interior, it is filtered from inside to outside by filtering net cylinder 1, all dirts more than aperture of filter screen size are trapped in filtering net cylinder 1,
Filtered clear water is delivered to upper jet pipe 24 and preceding jet pipe 25 by pressure water pump 28 by aqueduct 27, what preceding jet pipe 25 ejected
High pressure water flow pushes filter cylinder blade 17 that filtering net cylinder 1 is made to rotate, as filtering net cylinder 1 rotates, the dirt quilt being adhered on strainer
The high pressure water flow that upper jet pipe 24 sprays pours in sewage sump 3, and enters pollution discharge pond by blowdown axocoel 10, sewage draining exit 12 with flow
In 34,1 filtered clear water of filtering net cylinder continues into filtering ponds 32, and the clear water in filtering ponds 32 is entered by outlet pipe 33 manages
Road system is delivered to field pressurization or from by way of pressing；Then, in the blowdown axocoel 10 at blowdown through-hole 11
The accumulation of dirt, blowdown axocoel 10 gradually blocks, the water level in sewage sump 3 is gradually increasing, when the actual water level in sewage sump 3 is high
When liquid level sensor 30, liquid level sensor 30 sends a signal to controller and decontamination valve 15 is automatically turned on, in water inlet pipe 8
Pressure flow carries out cleaning down to blowdown axocoel 10 by branch pipe 14 of removing contamination and makes its dredging, the dirt accumulated in blowdown axocoel 10
Object enters with flow in pollution discharge pond 34, and the muddy water collected in pollution discharge pond 34 is filtered by return water strainer 37 after precipitation, passes through return water
Pipe 35, which enters in filtering ponds 32, to be used again, to be reduced as far as water consumption；Finally, when reaching preset duration of removing contamination
When actual water level value afterwards or in sewage sump 3 is down to 30 or less position of liquid level sensor, controller makes decontamination valve 15 close automatically
It closes, end of removing contamination, thereby realizes while filters irrigation water, clean-up operation can be carried out automatically as needed,
To under the premise of reducing energy consumption, considerably improve filter efficiency.
