Technical field
The utility model relates to a kind of automatic backwash blowdown water filters.
Background technique
When water power station water supply system is fetched water using tail water, water filter is usually arranged in water supply pump water outlet, to realize certainly
Clear formula automatic backflushing washes down blowdown, but this arrangement has the disadvantage in that
1. the branch of a large amount of silt particles and water float that contain in river, tree (grass) root, leaf and domestic pollution
Object etc. will be directed into water supply pump, will lead to water supply pump cisco unity malfunction and very causes to damage.
2. logical using the power station of this arrangement since water filter needs to realize self-cleaning type blowdown using pressure difference
Sewage pipe must be often connected to power station sump, there is certain limitation, and emissions to sump will also will increase
A possibility that sump draining pump damages.
In order to protect water supply pump, also there is part power station that traditional single-cylinder type water filter is arranged in the water inlet of water supply pump,
Backwash is carried out to water filter filter cylinder from the external pressure water source of the water outlet of water supply pump to remove contamination.But traditional single-cylinder type water filter
It is had the disadvantage that using this arrangement
1. filter cartridge size is necessarily larger, rotating filter cartridge both ends machining accuracy and assembly since filter cylinder can only use single-cylinder type
Gap it is difficult to ensure that, be also just difficult to ensure higher filtering accuracy requirement.
2. being necessarily contactless, the section in the gap of the non-contact part with backwash water cavity since filter cylinder is rotated
Product is quite big, and power plant tail water position is usually above the Installation Elevation of water filter, if dirt is immediately discharged to tail water, sewage draining exit tool
There is back pressure, direct losses can not be overcome the back pressure of tail water to carry out blowdown, only arrange dirt by the pressure at external backwash water source
To power station sump, and it thus will increase a possibility that sump draining pump damages.
