Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of fibre filter, as shown in Figure 1-Figure 3, it comprises filter fiber 1, and a minimum filter core 2, described filter fiber 1 is pencil and is arranged on described filter core 2.Some described filter fibers 1, in pencil, have good filtering function.Filter fiber 1 in pencil fixes through the installing hole in described filter core 2.Each described filter core 2 can be equipped with a branch of described filter fiber 1.
As depicted in figs. 1 and 2, wherein said filter fiber l is unequal in the length of described filter core 2 both sides, forms asymmetric setting, has good result like this for some filter medium.As shown in Figure 3, described filter fiber l is equal in the length of described filter core 2 both sides, and formation is symmetrical arranged.
As shown in Figure 4, can be installed on 2 described filter cores 2 at every Shu Suoshu filter fiber l.Described filter core 2 is in word order.
As shown in Figure 5,2 described filter cores 2 are equipped with filter fiber 1 described in three beams, wherein the described filter fiber 1 of two bundles is arranged on two described filter cores 2 respectively, and another Shu Suoshu filter fiber 1 restraints through 2 described filter cores 2 and two that described filter fiber 1 is vertical to be arranged.
Can be connected by described flexible piece 3 between 2 described filter cores 2, described filter core 2 word order.
Or on each filter core 2, three beams filter fiber 1 is housed, this three beams filter fiber 1 is cross-shaped arrangement centered by described filter core 2, and described flexible piece 3 is positioned at the position vertical with above-mentioned three beams filter fiber 1.
The spheroidal that described filter core 2 is made for plastics or oval spherical entity filter core, its diameter is 1.5-3mm.The root diameter (RD) of described fibre bundle is 1.0 ~ 2.0mm, and taper diameter is 1 ~ 80mm, and filament filament diameter is 1 ~ 500fim, and fibre bundle length is 30 ~ 80mm.
The situation of the utility model fibre filter when filtering is as shown in figure Fig. 6, filtered water water inlet pipe 5 is through water-locator, enter filter 4, filtered water flows out from filtered water outlet pipe 8, fibre filter is blocked by web plate 6, in order to avoid enter in water, during filtration, fibre filter is squeezed in filter 4 bottom, due to filter core 2 and filter tow 1 difference in specific gravity larger, certain compaction is had to filter bed, filter bed space slowly reduces from top to down, improves the utilization rate of fiber filtering body, increases the pollutant holding capability of filter bed.During the backwash of fibre filter filter bed, situation as shown in Figure 7, adopts compressed air together with water during backwash, and backwashing water is from backflushing water intake pipe 7, and air enters filter 4 from recoil air inlet pipe 9, and recoil Xian draining is discharged from washback drainpipe 10.Owing to filtering the difference in specific gravity of core 2 and filter tow l, under the effect of backwash current and air bubble, causing fibre filter to filter, core 2 collide mutually, interspersed between current and fiber, symmetric double tail whipping and inverting action, and bubble and interfibrous friction make the particle that fiber adheres to come off rapidly and reach and clean object thoroughly.Its fibre bundle of double-core fibre filter can mix for one or more in natural fiber, staple fibre, synthetic fibers, inorfil.
Monokaryon fibre filter of the present utility model, makes middle for monokaryon is solid, two ends filtrate is loose dissymmetrical structure by fibre filter.Because the list filter core proportion be made of plastics is greater than the proportion of symmetrical tail, when filtering, filter core serves the compaction to fibre bundle, filter bed is close and dirt-carrying precision is high, filter bed dirt-carrying ability and dirt-carrying precision first mate are improved, simultaneously, filter bed porosity also makes filter bed hydraulic resistance little by upper to little diminishing gradually, and the rate of filtration first mate degree in filter tank improves.Thus improve that the dirt-carrying ability of filter bed, filter area are large, filtering accuracy and solid-liquid separation efficiency high.When backwash, increased gradually by the bubble risen bottom filter tank, the bubble of filter tank lower curtate is greater than at the active force of top, filter tank bubble, the filtrate on filter bed top plants dirty amount greatly, the filtrate on top, filter tank is subject to larger effect and adapts, achieve large compared with dirty filtrate cleaning strength, in the difference in specific gravity due to monokaryon and asymmetric double tail, asymmetric double tail fibre bundle swings with backwash current, collision and stronger upset is produced between core, oscillating force, knockout press, also the mechanicals efforts that filtrate is suffered in water is exacerbated, the mechanicals efforts that when enhancing backwash, filtrate is subject to.The acting in conjunction result of several power makes the suspended particulate being attached to fiber surface be easy to come off above, thus drastically increases the wash degree of filtrate, and backwash water consumption is few and backwashing time is short.The cleaning of monokaryon asymmetric double tail fiber dimension filter bed can adopt separately forever flows backwash, compressed air, water and compressed air and replaces backwash, also can carry out water and the common backwash of compressed air.Larger save the power consumption of backwash and the water consumption of backwash and backwashing time.Because the difference in specific gravity of filtrate is in the effect adding intelligent self-pressure after backwash, filtrate can rapid and natural, intelligent layering, naturally fast form desirable filter course.Its effect is that filter bed space diminishes from top to bottom gradually, improve filter bed pollutant holding capability and capacity utilization, the feature of the general fiber molding filtrates such as fibre filter filter surface area is large, filtering accuracy is high, filtering velocity is fast, long service life, solid-liquid separation efficiency are high, filter bed pollutant holding capability is large.Another feature of monokaryon fibre filter to play intelligent self-pressure and layered effect, and filter bed space is diminished from top to bottom gradually, and the volume ratio in filter bed shared by fibre filter is large, and thus the filter table area of filter bed is large, filter bed capacity utilization is high.More effectively make use of the strained volume in filter tank.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any improvement of doing based on the utility model or modification all belong to the protection domain of the utility model claim.
