Description

A kind of heterogeneous body fiber filtering assembly

Technical field

The utility model belongs to the filtering material technology in water treatment field filter, relates in particular to a kind of formation of heterogeneous body fiber filtering assembly.

Background technology

Desirable filtrate is the upper lower close filtering layer of dredging, and the filtrate on upper strata carries out coarse filtration, so that increasing to greatest extent filtrate holding filth capacity in unit volume, the filtrate of lower floor carries out essence to be filtered, and makes sewage reach the object of fine filtering.In addition, when filtrate is carried out to backwash, need to meet increase back washing strength, the requirement in the short period of time filtrate being cleaned up.

Water treatment field is used more filtrate to be generally quartz sand, anthracite, ceramic particle, polyster fibre etc. now, is widely used, but the problem of bringing in actual production is never effectively solved in actual production.It is thin lower close for filtrate is presented, the use of general granular filter material is larger quartz sand, anthracite, the filter material of ceramics granules of filtering layer top filling particle diameter, the less above-mentioned filtrate of bottom filling particle diameter, and so-called multimedium filtrate, although can meet the needs of filtration, but, when back washing strength increases, very easily make disorderly layer and race material of the different filtrate of particle diameter, lose the lower close state of dredging, back washing strength reduces and filtrate can not be cleaned up, and the contradiction while making filtrate carry out backwash increases.When using fiber as filtrate, although can there is not disorderly layer and the phenomenon of running material in fiber filtering, but, because the fiber number of fiber is identical, cause thin lower close perfect condition on filtrate to reach, in addition, be generally that fiber filtering is processed into spherical or is piled up in filter loose granular filter material, cause when filtrate backwash, filtrate and backwash current flow simultaneously, relative velocity between the two is less, causes filtrate to be difficult for rinsing well.

Utility model content

While being to provide the good and backwash of a kind of result of use, can there is not disorderly layer and run the heterogeneous body fiber filtering assembly of material phenomenon in the purpose of this utility model.

For achieving the above object, the utility model has adopted following technical scheme:

A kind of heterogeneous body fiber filtering assembly, it comprises:

Have the base spacer of a level or nearly horizontal positioned at least, on it, arrange in length and breadth several water holes;

The filtrate fixed mount that some parallel rows establish, is separately fixed on base spacer, and each filtrate fixed mount all has a facade plate, is provided with row's filtrate perforation on this facade plate;

Perforation place of each filtrate wears one group of fibre bundle and forms single filter element, and this group fibre bundle at least comprises the fibre bundle of two sections of different fiber numbers, is from top to bottom to be connected successively to thin fibre by thick fibre, and each section fibre interfascicular is by stopper tight joint; Wherein, being positioned at section of the end is fixed in filtrate perforation the lower end of thin fine fibre bundle.

The filtrate fixed mount of described heterogeneous body fiber filtering assembly adopts angle steel to make.

The utility model has the advantages that: can well complete the in-depth filtration of filtering layer, the race material in the time of solving backwash filtrate again, a difficult problem for random layer, and backwash is quick.

Fig. 2 is the structural representation (in use, filter is in filtration condition) of the utility model heterogeneous body fiber filtering assembly.

Fig. 3 is that the structure of the single filter element of the utility model is put schematic diagram.

In figure:

1-filter housing; 2-base spacer; 3-water hole; 4-filtrate fixed mount; The perforation of 5-filtrate; 6-fine fibre bundle; 7-stopper; 8-coarse fiber bundle; 9-three-way diverter valve; 9.1-filter mouth of a river of advancing; 9.2-recoil water outlet; 10-three-way diverter valve; Delivery port after 10.1-filter; 10.2-recoil water inlet.

Below in conjunction with drawings and the specific embodiments, the utility model is described further.

The specific embodiment

Referring to shown in Fig. 1 to Fig. 3, the common filter material layer unit forming of single filter element that the utility model heterogeneous body fiber filtering assembly mainly includes base spacer, filtrate fixed mount and has the some row of the some rows of transverse and longitudinal to arrange.

Described base spacer 2 is support units of utility model heterogeneous body fiber filtering assembly, is at least one, or is put together by polylith, is generally level or nearly horizontal positioned, becomes several rows and every row to arrange several water holes 3 on it.

The utility model heterogeneous body fiber filtering assembly has the filtrate fixed mount 4 that some parallel rows establish, and is separately fixed on base spacer 2, and each filtrate fixed mount 4 all has a facade plate, is provided with row's filtrate perforation 5 on this facade plate.In the present embodiment, these filtrate fixed mount 4 use angle steel are made, and on its angle steel facade, are designed with several filtrate perforation 5, shown in Fig. 2 and Fig. 3.

Each filtrate on filtrate fixed mount 45 places of boring a hole wear one group of fibre bundle (being a single filter element), this group fibre bundle at least comprises the fibre bundle of two sections of different fiber numbers, they be to be connected successively by thick fibre to thin fibre from top to bottom, and each section fibre interfascicular is by stopper 7 tight joints; Wherein, being positioned at section of the end is fixed in filtrate perforation 5 lower end of thin fine fibre bundle, one end of the coarse fiber bundle 8 of the other end of the fine fibre bundle 6 of below and its top joins fastening with stopper 7, has completed being used in combination of the different filtrates of two or more fiber number, shown in Fig. 2 and Fig. 3.

Filter is an airtight container, base spacer 2 is arranged on the below of container, on base spacer 2, arrange in length and breadth several water holes 3, be fixed in addition the filtrate fixed mount 4 on dividing plate 2, filtrate fixed mount 4 use angle steel are made, on its angle steel facade, be designed with several filtrate perforation 5, the lower end of fine fibre bundle 6 is fixing through filtrate perforation 5 use stoppers 7.

Operation principle of the present utility model and the course of work are: when the normal drainage of filter, need the sewage filtering to enter from the filter of the three-way diverter valve 9 of the filter housing 1 top mouth of a river 9.1 of advancing, through the larger coarse fiber bundle 8 of fiber number, bulky grain in sewage is trapped, sewage continues to be passed down through fine fibre bundle 6, in the fine particle in sewage, holds back, and the current after filtration are through after water hole 3, by delivery port 10.1 after the filter of three-way diverter valve 10, discharge, complete the filtration to sewage.

When filter needs backwash, first simultaneously the path of switching three-way reversal valve 9,10, backwash current enter from the recoil water inlet 10.2 of three-way diverter valve 10, through water hole 3, fine fibre bundle 6 and coarse fiber bundle 8 have been rushed, because one end of filtrate is fixed on filtrate fixed mount 4, relative velocity between backwash current and filtrate increases greatly like this, be conducive to the flushing to filtrate, current after flushing and impurity are discharged by the recoil water outlet 9.2 of three-way diverter valve 9 simultaneously, have completed the work of backwash.

The various embodiments described above can not depart from some variations in addition under scope of the present utility model, thus above explanation comprise should be considered as exemplary, but not the protection domain of applying for a patent in order to limit the utility model.
