Abstract
The invention relates to the field of water purification and particularly relates to a filter membrane component and a preparation method thereof. The filter membrane component comprises a mounting plate and a membrane component mounted on the mounting plate. The membrane module comprises a support layer, the first filter layer covered on the supporting layer, a fixed bed covered the first filter layer and the second filter layer coated on the fixed bed. The filter membrane component and preparation method thereof has the advantages of no longer needing additional fixed layer and fixed structure. The reason why adopting intermediate winding nylon fiber cloth and PVDF coating outside again is that the film is more tough, difficult to damage and debris is not easy to enter while reverse flushing. By the adoption of the design of the removable module, the membrane component is more convenient for the replacement and cleaning.

Filtering film component changing and preparation method thereof.
A kind of filtering film component, including installing plate and installation membrane module on a mounting board, described membrane module includes propping up
Support layer, in supporting layer outer cladding first filter layer, in the first filter layer outer cladding fixed layer, filters in fixed layer outer cladding second
Layer.
Further, described supporting layer is the support tube of some straight line arrangements.
Further, described support tube adopts internal diameter 0.5-2mm, and phosphorus content is more than 95% activated carbon fiber pipe.
Further, it is added with nontoxic, stable chemical nature metal material in described activated carbon fiber pipe.
Further, described first filter layer is made using activated carbon fiber polyvinylidene fluoride composite material.
Further, described second filter layer is made using pvdf material.
Further, described fixed layer is made using nylon fiber cloth.
Further, described membrane module has some pieces, is provided with joint at membrane module two ends, and described installing plate includes upper and lower
Symmetrically arranged upper mounting plate and lower installation board, upper mounting plate and lower installation board are provided with some installing holes, described membrane module
The joint at two ends is embedded in installation in the hole.
Further, described installing hole is obliquely installed.
A kind of preparation method of filtering film component, the method comprises the following steps:
It is more than 95%, the activated carbon fiber pipe of internal diameter 0.5-2mm from phosphorus content, itself and comb are arranged to numerical value more than 8；
Brush wraps up in the first filter layer that activated carbon fiber polyvinylidene fluoride composite material is made；
When the mass dryness fraction of the first filter layer is 50%, carry out nylon fiber cloth cladding；
At a temperature of 50-200 DEG C, outside nylon fiber cloth, brush wraps up in the second filter layer that pvdf material is made；
At a temperature of 150-190 DEG C, at the two ends of the above-mentioned assembly completing, thermoplastic is carried out using polystyrene solid
Determine molding and make joint.
The invention has the beneficial effects as follows: it is no longer necessary to additionally increase fixed layer, self structure is fixed, mid-wrap nylon
Fiber cloth, when outside is because carrying out back flush from pvdf coating again, film is more tough and tensile, is hardly damaged, and debris are not yet
It is easily accessible；Using dismountable modularized design, the replacing of more convenient membrane module and cleaning.
Brief description
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is overall structure diagram of the present invention；
Fig. 2 is the upward view of the present invention；
Fig. 3 is the structural representation of inventive film assembly.
Specific embodiment
Below in conjunction with accompanying drawing, technical scheme is further described, but the present invention is not limited to these in fact
Apply example.
As shown in figure 1, the technical scheme is that: a kind of filtering film component, including installing plate 1 and be arranged on installing plate
Membrane module 2 on 1.Installing plate 1 both sides are provided with installing hole 11, and membrane module 2 is installed in Rose Box by installing hole 11.
In conjunction with accompanying drawing 2, described membrane module 2 has some pieces, is provided with joint 21 at membrane module 2 two ends, and described installing plate 1 includes
Upper and lower symmetrically arranged upper mounting plate 12 and lower installation board 13, upper mounting plate 12 and lower installation board 13 are provided with some inclinations
The installing hole 11 of setting, the joint 21 at described membrane module 2 two ends is embedded in installation in the hole.Membrane module 2 tilts again parallel setting, increases
Add filter area, improve filter effect；The modular removable design of membrane module 2, is easy to maintain, easily substitutes and damage
Bad part.
As shown in Figure 3, membrane module 2 includes supporting layer 22, in supporting layer 22 outer cladding the first filter layer 23, in the first mistake
Filtering layer 23 outer cladding fixed layer 24, in fixed layer 24 outer cladding the second filter layer 25.
Wherein, supporting layer 22 is the support tube of some parallel arrangements, and support tube 22 adopts internal diameter 0.5-2mm, and phosphorus content
Activated carbon fiber pipe more than 95%, this activated carbon fiber pipe tensile strength is high.Be added with activated carbon fiber pipe nontoxic,
The metal material of stable chemical nature, increases its stability.
Wherein, the first filter layer 23 is made using activated carbon fiber polyvinylidene fluoride composite material, and activated carbon fiber gathers partially
Fluoride composite material acf＆pvdf (activated carbon fiber＆poly vinyli-dene fluoride), existing
On the basis of some pvdf materials, compound interpolation activated carbon fiber, has more preferable adsorption effect.In addition, the second filter layer 25 is adopted
Made with the pvdf material first having, when carrying out back flush, film is more tough and tensile, is hardly damaged, and debris are also not easily accessed.This
Bright cover pressure double-deck acf＆pvdf-pvdf filter membrane design using unique, filter effect is splendid.
In addition, acf＆pvdf has the intensity of superpower resistance to stress, shearing in itself, fixed layer 24 adopts nylon fiber cloth,
Improve tension further and rise intensity.
The invention still further relates to a kind of preparation method of filtering film component, the method comprises the following steps:
