Abstract
一种纤维过滤器，包括纤维滤层、上承托板、下承托板，纤维滤层由多束短纤维束和多根细绳构成，多束短纤维束的一端均匀地固定绑结在一根细绳上，短纤维束的另一端完全松散，细绳的两端分别固定在上下承托板上。本实用新型与现有技术相比，具有过滤精度高、截污容量大，过滤周期长且运行阻力小，反冲洗方便，上承托板不会出现卡阻的优点。
A fiber filter, including a fiber filter layer, an upper support plate, and a lower support plate, the fiber filter layer is composed of a plurality of short fiber bundles and a plurality of thin ropes, and one end of the plurality of short fiber bundles is evenly fixed and tied on the On a thin rope, the other end of the short fiber bundle is completely loose, and the two ends of the thin rope are respectively fixed on the upper and lower supporting plates. Compared with the prior art, the utility model has the advantages of high filtration precision, large sewage interception capacity, long filtration period, small running resistance, convenient backwashing, and no jamming of the upper supporting plate.
Description
(1) technical field
The utility model relates to a kind of processing filter plant of purifying waste water, the especially a kind of various suspensions removed in the water and fabric filter of organic matter colloid of being mainly used in.
(2) background technology
At present, the fiber filter equipment on the market, its filter material layer mainly by long fibre bundle filtrate, fiber-ball filter media, huddle short-fibre silk filtrate etc. and constitute.The fabric filter that is made of filter material layer the long fibre bundle is prone to supporting plate jam phenomenon, and because fibre bundle is longer, the trapped substance of tow inside is difficult for cleaning up; The centre of fiber-ball filter media is difficult for cleaning; The filament that huddles the short-fibre silk filtering material filter easily twines, and whole filtering layer becomes piston-shaped with liter waterborne during backwash, can't form the scrubbing action of certain dynamics, and cleaning performance is poor.
(3) summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of rate of filtration height, retaining power is big, water consumption is low, backwash is clean, stable, simple in structure fabric filter.
The technical solution of the utility model realizes in the following manner: the fiber filtering layer is made of short fiber bundle and cord, and an end stitch of short fiber bundle is on cord, and the other end is loose fully, and the two ends of cord are separately fixed at up and down on the supporting plate.Because fibre bundle is shorter, under the agitaion of ascending air bubble, the short fiber bundle produces and swings fiercely and get rid of and drag, and with comparalive ease the suspended material of holding back is cleaned from fibre bundle.
Stitch is on a cord equably for multi beam short fiber bundle, and many cords are evenly distributed on supporting plate and the following supporting plate.Last supporting plate is a removable orifice plate, and following supporting plate is fixing orifice plate.Moving up and down of last supporting plate, the function with backwash is filtered in realization.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 be filtered water inlet and backwash delivery port, 2 for tank body, 3 for lowering or hoisting gear, 4 for last supporting plate, 5 for cord, 6 is the short fiber bundle, 7 are supporting plate down, 8 are the backwash air inlet pipe, 9 for filtering water outlet and backwash water inlet.
(5) specific embodiment
During filtration, apparatus for automatically lifting 3 reaches upward, and supporting plate 4 drops to certain altitude, the filtering layer height that is made of short fiber bundle 6 and cord 5 is reduced, reach certain packing (little voidage), former water enters from fabric filter top water inlet 1, by the fiber filtering layer, suspension is retained in the filtering layer in the water, and filter back water is discharged from bottom delivery port 9.
During backwash, stop into water, open backwash delivery port 1, open backwash water inlet 9 and air inlet 8, air enters fabric filter, under the effect of air, lowering or hoisting gear 3 rises to the highest spacing automatically, with filtering layer expansions that stretch fully of compression, and the bigger space of maintenance between each the short fiber bundle 6 in the filtering layer, because an end of short fiber bundle 6 is fixed on the cord 5, the complete loose freedom of the other end under the agitaion of ascending air bubble, produces short fiber bundle 6 and swings fiercely and get rid of and drag, produce collision between the filament and between each fibre bundle 6, mechanical friction and kneading action are removed the end with the suspended material of holding back from filament and are cleaned.Gas, water recoil behind the certain hour simultaneously, can close recoil water, and gas is towards certain hour separately, and then gas, the water certain hour that recoils simultaneously.Backwashing water is taken away the suspension that rinses out, and filtering layer is rinsed well.After backwash finishes, apparatus for automatically lifting 3) reduce to and filter height, enter next filter cycle.
Claims (3)
1, a kind of fabric filter, comprise fiber filtering layer, last supporting plate, following supporting plate, it is characterized in that: the fiber filtering layer comprises short fiber bundle and cord, and an end stitch of short fiber bundle is on cord, the other end is loose fully, and the two ends of cord are separately fixed at up and down on the supporting plate.
2, fabric filter according to claim 1 is characterized in that: stitch is on a cord equably for multi beam short fiber bundle, and many cords are evenly distributed on supporting plate and the following supporting plate.
3, fabric filter according to claim 1 is characterized in that: going up supporting plate is removable orifice plate, and following supporting plate is fixing orifice plate.
