Description
Technical field
The technical field of sewage disposal equipment is the utility model is related to, more particularly, to a kind of active sand filter plant and dirt
Water filtering system.
Background technology
Sand extraction tube is applied in active sand filter, and the principle of active sand filter processing waste water is that sewage flows from top to bottom
By the quartz sand filter media in filter, dirty effect is cut by raw water filtration by quartz sand filter media.In the process, quartzy sand filtration
The content increase of pollutant in material, and the pollutant load of lower floor's filter material layer is higher than upper strata filter material layer.In filter bottom
The bottom active sand for retaining pollutant is promoted to filter by the air lift of centre under the action of air compressor machine by sand extraction tube
Cleaned in the sand-washing device at top, the active sand after cleaning returns to filter bed, while cleaning produced pollution beyond the region of objective existence is arranged, and is reached with this
To the purpose of circular treatment.Quartz sand filter media carries out always during cleaning with water process, and sand extraction tube transmits carried always
The quartz sand filter media risen, this wearability to sand extraction tube have very high requirement.
Sand extraction tube in traditional activated sand filter uses polypropylene PPR materials, its advantage is：(1) polypropylene PPR is ring
Material is protected, is not easy that burn into is less scaling, is not easy to grow bacterium, meets national water hygiene index request；(2) connector uses
Hot-melt adhesive paste is integrally formed, and compared to the silk mouth connection mode of other materials, hot-melt adhesive paste has the advantage in interface ne-leakage,
Also avoid gluing toxicity at the same time；(3) polypropylene PPR pipe is smooth, and transporting resistance is small；(4) it is cheap moderate, easily by city
Field receives.
However, conventional polypropylene PPR material sand extraction tubes have the disadvantages that：(1) sand extraction tube in active sand filter
Lifting medium is that particle diameter is less than the natural sea sand filtrate that 1.5, silicon content is high, hardness is big for 1.2-2.0mm, nonuniformity coefficient, than
Other conventional pumped (conveying) medium Ru Shui, oil etc. require higher to the wearability of pipeline material, are found in multiple projects run,
During quartz sand filter media is lifted, tube wall occurs grinding cut, non-uniform mill by quartz sand on conventional polypropylene PPR pipe road
Thin or even mill leakage phenomenon, its average life is only that 2-3 is just needed to change, increase replacement cost, operation expense；
(2) sand extraction tube inner wall it is rough cause to carry sand transporting resistance become larger, it is bad to cut dirty filtrate cleaning performance；If mill leakage is not in time
It was found that the problem of equally filtrate being caused to clean.Filtrate cleans not in time, and waste water filtering effect is bad, and water outlet does not reach
Mark, and for a long time, the pollutant being attached on filtrate can form mycoderm under anaerobic environment and cause filtrate hardened, filter tank event
Barrier.Filter tank is once hardened, and solution difficulty is larger, and expense is also higher, greatly increases operation expense.
Based on problem above, propose a kind of with wearability is good, service life is long, the filter plant of the low sand extraction tube of cost is shown
It is particularly important that obtaining.

It is not susceptible to deform after the extruding of water or damages.
In the optional technical solution of the present embodiment, the bottom of sand extraction tube 100, which is provided with, carries sand pump 200, and top, which is provided with, to be washed
Sand device 300；When extraneous high-pressure air source to carry be filled with gases at high pressure in sand pump 200 when, can be by active sand filter plant bottom
Dirty sand is lifted to sand-washing device 300 by sand extraction tube 100 and cleaned.
Active sand filter plant when being filtered to sewage, sewage by filter material layer can by the pollutant in sewage into
Row intercepts, and then flows out clear water.However, by long-time filter sewage process, a large amount of pollutants are adsorbed on filtrate, so that shadow
Filter effect is rung, based on this, it is necessary to be cleaned to filtrate.In the present embodiment, it is provided with the bottom of sand extraction tube 100 and carries sand pump
200, this carries sand pump 200 and uses air lift, sand-washing device 300 is provided with the top of sand extraction tube 100, so, by outer
Boundary's high-pressure air source to carry be passed through gases at high pressure in sand pump 200 when, gas pressure effect under, carrying sand pump 200 can be by bottom
Dirty sand is lifted by sand extraction tube 100 and is rinsed in sand-washing device 300, filtering material particle can be separated with pollutant and be reached clear
The purpose washed, filtrate returns to casting bed after over cleaning using dead weight, and cleaning sullage is then discharged to the external world.Also, washed-out sand process
Carried out together with filter process so that filtrate can be carried out continuously cleaning, to improve the filter effect to sewage of filtrate.
In the optional technical solution of the present embodiment, the outside of sand extraction tube 100 is provided with support tube 400, sand extraction tube 100 and support
Multiple fixing pieces 500 are provided between pipe 400；Sand extraction tube 100 can be fixed in support tube 400 by fixing piece 500.
