Description
Technical field
The utility model belongs to filter, specially a kind of automatic gravity backwash filtering device.
Background technology
Back-flushing filtering device can be with backwashed filtering layer due to it, it is to avoid frequently artificial cleaning or change filter layer,
The need for meeting the continuous operation of equipment, automatic gravity backwash filtering device is the recoil that filter layer is realized by Action of Gravity Field
Wash, save the supplement of external force, so as to save the consumption of the energy, therefore be now widely used for sewage treatment area.It is used as
The filtrate of automatic gravity backwash filtering device mainly has fiber filtering, granular filter material and biological film filtering material etc..Fiber filtering
There are two kinds of forms of fibre bundle and fibrous nodules, fibre bundle two ends are fixed, the fiber that bound two ends have 200mm or so long cannot be clear
Wash clean, causes the quick exhaustion of filtering layer, is accomplished by stopping production quickly and changes filtering layer, and rinse water cannot be saturating when fibrous nodules are due to backwash
Cross at colligation, easily forming sand core bacterium long causes balling, finally has to change filtering layer in short term, once and pine at the colligation of center
It is dynamic, will hair loss until be all scattered, fiber will enter with water and leach end, have a strong impact on filter quality；Though biological film filtering material
Right filtering accuracy is high, but filtrate high cost, is not suitable for the filtering of general sanitary sewage and light polluted source；Granular filter material has
Silica sand, anthracite and ore etc., silica sand are generally used due to wide material sources and with low cost, when doing filtrate using silica sand,
The method for using at present is to be deposited in silica sand naturally to form layer of sand as filter layer in automatic gravity backwash filtering device, by
It is loose structure in the silica sand stacked naturally, therefore only piles up certain thickness and can just play a role in filtering, therefore layer of sand is anti-
It is difficult to be rinsed during flushing totally, for a long time using layer of sand contamination and plugging is easily caused, water-flowing amount is reduced, it is necessary to silica sand is moved
Go out, artificially cleared up or changed, and loose sand layer of sand surface in filtering is easily loose because of water, influences filter quality, and
Sand phenomenon is leaked during backwash serious.
