Description
Technical field
The utility model relates to a kind of fondant filter filter core, specifically relates to a kind of melt filter core of producing for spandex.
Background technology
Polyester fondant quality in spandex fiber production is the key link of spandex production process, because spinned strand diameter is very thin, spinneret orifice is very little, do not allow in melt to be mixed with any impurity or gel particles, therefore in the melting high-speed spinning forming process, want to improve spinning quality, guarantee production stability, filter particularly melt filter core is essential and very crucial parts.
Melt filter core in spandex production is mainly used in impurity and the particle in filtering liquid, is mostly to adopt metallic fiber sintered felt to be folded into bellows-shaped to process.For guaranteeing outgoing, filtering accuracy requires very high.Therefore the current many dependence on import of filter core, be mostly Korea S and produce, and price is high, and delivery cycle is long.Also there is the metal sintering felt that adopts Belgian BEKAERTGROUP to produce in state inner filter core manufacturer, but, because the uneven of wave technology rolled over by filter core manufacturer, the damage to the metal sintering felt in process is difficult to control.And in use find, the pressure loss of import melt filter core is fast, just can reach 20bar about 15 days left and right Pressure Drops greatly, needs can use after cleaning and regeneration.And at present, sintering felt filter element regeneration flow process mode commonly used is in the world:
1. about the filter core Pressure Drop reaches 2.0Mpa, quit work, pull down cleaning;
2. filter core being put into to solvent soaks.Make the inner residual abundant dissolving of filter core sintering felt;
3. put into drying box after filter element cleaning and heat, will not dissolve the part high temperature cabonization.
4. after taking out, filter core is put into to supersonic wave cleaning machine, go out carbonization by the ultrasonic wave high frequency oscillation residual.
5. use water under high pressure, or compressed air, carry out surface and blowback and clean;
6. do bubble test after cleaning, detect the filter core varying aperture, regeneration completes.
The complex process of regeneration, also have harm to operating personnel.And after repeatedly regenerating, the sintering felt also can produce varying aperture, thereby affects filter effect.Though the domestic manufacturer of having adopts domestic sintering felt to become the melt filter core, be that the aperture uniformity or anti-processing characteristics aspect all are difficult to reach instructions for use.
The utility model content
For the defect of prior art, the purpose of this utility model is to provide that a kind of filter effect is suitable with the metallic fiber sintered felt filter core, and pressure rise is slow, and first pressure reduction is lower than fiber sintering felt filter element, with low cost, the melt filter core of producing for spandex.

A kind of melt filter core of producing for spandex; comprise bracing frame and cross filter core cylinder; crossing the filter core jacket casing is located on bracing frame and is welded as a whole with bracing frame; wherein; cross the hollow cylinder of filter core cylinder for being welded into by the stainless steel sintered meshwork, the stainless steel sintered meshwork comprises protective layer, key-course, dispersion layer, the first casing play and the second casing play five-layer structure from outside to inside successively.
The utility model also can further be realized by the following technical solutions:
The described melt filter core of producing for spandex, wherein, described key-course adopts reverse mesh grid, and described protective layer and dispersion layer adopt the square hole mesh grid, and the first casing play and the second casing play adopt the fine groove mesh grid.
The described melt filter core of producing for spandex, wherein, described key-course adopts the reverse mesh grid that filtering accuracy is the 1-150 micron.
The described melt filter core of producing for spandex, wherein, described the second casing play inboard also is provided with one deck diffusion layer, and it is 6 orders that diffusion layer adopts aperture, the square hole mesh grid that string diameter is 0.8mm.
The described melt filter core of producing for spandex, wherein, it is 100 orders that described protective layer and dispersion layer all adopt aperture, the square hole mesh grid that string diameter is 0.1mm; Described the first casing play and the second casing play adopt 12 orders * 64 purpose fine groove mesh grids.
The described melt filter core of producing for spandex, wherein, support frame as described above adopts punching stainless steel coiled sheet to be welded into, or adopts the steel pipe punched on tube wall to make.
Owing to having adopted above technical scheme, the utility model possesses following technique effect:
1) the melt filter core of producing for spandex of the present utility model, adopt the stainless steel sintered meshwork to substitute the sintering felt as filter core, because the stainless steel sintered meshwork forms by vacuum-sintering, can reach the not fusion welding of contact point of each, form many empty, constitutionally stable filtering materials of high-voidage, the open-work rate is up to 28%, intensity is large, and evenly and in gradient arrange in aperture, during filtration, can effectively spread, do not produce dead angle, good filtration effect; Stainless steel sintered meshwork filter core is through folding, and the characteristic such as the intensity of stainless steel sintered meshwork is large, and evenly and in gradient arrange in aperture, high temperature resistant. in regenerative process, dissolving, and high temperature, concussion, clean link, and solvent more easily permeate, residual more easily disengaging.Its regeneration effect will be better than the sintering felt filter element far away.
2) key-course adopts high-precision reverse mesh grid, has better filtering accuracy, and higher open-work rate is combined with the protective layer, dispersion layer, casing play and the steel pipe with holes that adopt other mesh grid, and filter effect is better, and the bulging ability is stronger.
3) set up one deck diffusion layer between casing play and bracing frame, it is 6 orders that diffusion layer adopts aperture, the stainless (steel) wire that string diameter is 0.8mm, can effectively prevent that casing play 12 orders * 64 purpose fine groove mesh grids are close to bracing frame steel pipe with holes, thereby the material after filtering can pass through fully from the hole of bracing frame after by sintered meshwork.
4) the best employing of protective layer and dispersion layer aperture is 100 orders, the square hole mesh grid that string diameter is 0.1mm; The best employing of casing play 12 orders * 64 purpose fine groove mesh grids, key-course adopts the reverse mesh grid that filtering accuracy is the 1-150 micron, the most rational aperture of the best that is combined as like this coordinates, and can effectively increase working strength and the rigidity of stainless steel sintered meshwork when integrally welded.
5) the melt filter core of producing for spandex of the present utility model, through evidence, its filter effect and metallic fiber sintered felt filter core are basic identical, but the pressure reduction rising is slower, and first pressure reduction is well below the sintering felt filter element.And the stainless steel sintered meshwork cost price that the utility model adopts only has the 1/5-1/3 of metal sintering felt, can greatly reduce the cost in spandex production.
