2nd, back purge system 4 connects；Control device 5 is closed according to the first control instruction (backwash instruction) control water inlet closing device 2
After the water inlet of water feed apparatus 1, back purge system 4 is opened；Control device 5 recoils according to the second control instruction (instruction of pouring water) control
After cleaning device 4 is closed, water inlet closing device 2 is opened, the water inlet for making water feed apparatus 1 is opened.Control device 5 refers to according to the 3rd control
The water inlet for making (shutdown command) control water feed apparatus 1 is closed.
When using, control device automatically controls the folding of water inlet closing device, when filtering irrigation water is needed, control
Device control water inlet closing device is opened, and needs the irrigation water for filtering to enter in water feed apparatus, afterwards by filtering mesh bag
Filtration enter in settling pit.When needing to be rinsed filtering mesh bag, control device automatically controls water inlet closure dress
Closing is put, while control tractor traction block filtering mesh bag is pushed in the water stream channel of water feed apparatus, is automatically controlled afterwards
Start pollutant discharge vacuum pump, start to be rinsed the filtering mesh bag in water stream channel.
In the technical scheme that the present invention is provided, filter is provided with control device, can be intake by control device control
The folding of closing device, and then the water inlet switch of water feed apparatus is controlled, with timed unit back purge system can be controlled to mistake
Filter-screen bag is rinsed.Compared to existing technology, sandrock filter is adopted filter, sandrock filter is using the sandstone copied more
Screening formula filtration system adds stacked filtration system using sandstone, is all manually to control, system automation low degree.
The filter of the present invention can carry out the filtration of automatic control filter and the backwash of filtering mesh bag by control device, no
Need to manually control, high degree of automation.
As shown in figure 1, specific, water feed apparatus 1 include horizontally disposed first pipeline 11 and hang down with the first pipeline 11
The second pipe 12 of the straight connection of bending downwards；Water inlet closing device 2 is arranged on the entrance of the first pipeline 11；Filtering mesh bag 3
Entrance is connected with the bottom of second pipe 12.
First pipeline of water feed apparatus is connected so horizontally disposed with water channel, and second pipe outlet is connected with filtering mesh bag,
The second pipe one end for bending vertically downward connects the first pipeline, and the other end is towards settling pit, the water energy after filter screen bag filtration
Enough flow directly into settling pit.
As shown in figure 1, specific, filtering mesh bag 3 is flexible filter mesh bag.In backwash, flexible filtering mesh bag can
Turn when into water stream channel, be easy to rinse by the pollutant on filtering mesh bag.And the filtering mesh bag of flexibility
A part for lower end is stretched in the water of settling pit, and when filtering, water flows into filtering mesh bag, filtering mesh bag from the top of filtering mesh bag
Can swing back and forth with the impact of current, pollutant will not be gathered in the surface of filtering mesh bag, the effect for filtering be improved, while mistake
Filter-screen bag is not easy blocking.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, all should contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by the scope of the claims.
