Description

The hollow fiber ultrafiltration membrane filter

Technical field

The utility model relates to the ultrafiltration apparatus in a kind of water treatment field, specifically, is a kind of hollow fiber ultrafiltration membrane filter.

Background technology

At present, at the employed hyperfiltration membrane assembly of water treatment field, generally its putamina adopts lucite tube, and is fragile, and resin distribution is inhomogeneous during cast, and difficulty is installed, and flux is little.The hyperfiltration membrane assembly putamina that has adopts the UPVC pipe, and urceolus adopts the ABS engineering plastics, when two kinds of unlike materials are glued, occur the not firm feelings picture of bonding easily, thereby cause leaking, and UPVC manages hot strength and toughness is relatively poor, usually show as fragility, the low and easy fracture of percentage elongation.Generally be threaded or directly press packing ring, also easily leak when being connected outward by poor sealing for hermetically-sealed construction.The water-locator water (flow) direction adopts large tracts of land perforate cross-flow type, has increased the impulsive force to the film silk, along with the increase of inflow, and the fatigue fracture that the film silk can be too early.

Summary of the invention

The purpose of this utility model then is at present above-mentioned the deficiencies in the prior art, and a kind of good airproof performance is provided, and easy to assembly, flux is big, and the film silk is the hollow fiber ultrafiltration membrane filter of easy fracture not.

The technical solution adopted in the utility model is as follows:

A kind of hollow fiber ultrafiltration membrane filter, it includes film spare main body its feature, film spare main body upper and lower side all is with urceolus, film spare body interior is provided with doughnut, the upper end of doughnut is provided with water-locator, its lower end is provided with film lattice support member, the water distributing pore aperture of described water-locator is with becoming big from water inlet gradually apart from increase, and they are provided with ringwise, the urceolus top of film spare main body upper end connects upper end, the urceolus bottom of film spare main body lower end connects lower end, and the lower end lower end is provided with port.

Described urceolus and film spare main material are the ABS engineering plastics.

Described film lattice support member is provided with 6 lattices that are evenly distributed.

The described film spare main body urceolus at two ends up and down all is connected sealing by sealing ring with upper end, lower end respectively.

The junction of the urceolus at two ends and upper end, lower end is provided with fastener about the described film spare main body, and described fastener spots weld the degree of 90 on steel band circle segmental arc module by 4 and assembles.

The beneficial effects of the utility model have:

Good looking appearance is made easy to assemblyly, and flux is big, good seal performance.Urceolus and film spare main body impact strength are higher, and chemical stability is strong, and pliability is good.The special open-celled structure of water-locator had both guaranteed that backwash or water inlet water distribution were even, and because water (flow) direction is parallel with film silk direction, had reduced the impact to the film silk, can not make the film silk tired or rupture the service life of having improved film.

Fig. 2 is the structural representation of the utility model water-locator.

Fig. 3 is the structural representation of the utility model fast-assembling fastener.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, film sparemain body 7 upper and lower sides of the present utility model all are withurceolus 6, and film sparemain body 7 inside are provided withdoughnut 11, and the upper end ofdoughnut 11 is provided with water-locator 9, and its lower end is provided with film lattice support member 5.As shown in Figure 2, the water distributing pore aperture of the utility model water-locator 9 is with increasing fromwater inlet 10 distances and becoming big gradually, and they are provided with ringwise, water-locator 9 adopts the grooved base perforate to carry out water distribution, the principle that water distributing pore perforate size is directly proportional with the water inlet flow path according to the water distributing pore cross section, little and few from the near local perforate of water inlet, many and big from water inlet local perforate far away, along perforate all around, guarantee that backwash or water inlet water distribution are even, water (flow) direction is parallel with film silk direction, has reduced the impact to the film silk, can not make the tired or fracture of film silk, more efficient like this service life of improving film.Urceolus 6 tops of film sparemain body 7 upper ends connectupper end 8, andurceolus 6 bottoms of film sparemain body 7 lower ends connectlower end 2, andlower end 2 lower ends are provided with port one.

Urceolus 6 of the present utility model is the ABS engineering plastics with film sparemain body 7 materials, and by unified material ABS special glue bonding, with a kind of material bonding firmly, and ABS engineering plastics good combination property, impact strength is higher, and chemical stability is strong, and pliability is good.

Filmlattice support member 5 of the present utility model is provided with 6 lattices that are evenly distributed, and makes when pouring resin and assembling more convenient.

Theurceolus 6 at the utility model film spare main body two ends about in the of 7 all is connected sealing by sealingring 3 withupper end 8,lower end 2 respectively, and in assembling place of sealingring 3 groove is set and fixes, and can prevent that like this sealing ring is loosening, good seal performance.And theurceolus 6 at film spare main body two ends about in the of 7 is fixing byfastener 4 with the junction ofupper end 8, lower end 2.As shown in Figure 3, fastener 4 spots weld the degree of 90 on thesteel band circle 9segmental arc module 10 by 4 and assembles, andsolder joint 11 evenly distributes in 90 degreesegmental arc modules 10, required like this processing mold is little, the convenient making, and cost is low, it is convenient to install, and good seal performance can not produce drainage.

Other undeclared part that the utility model relates to is same as the prior art.
