Detailed description of the invention
And the present invention is described in detail in conjunction with the embodiments below with reference to the accompanying drawings.It should be noted that, when not conflicting, the feature in following embodiment and embodiment can combine mutually.
In one of them embodiment of the present invention, a kind of hollow fiber membrane cartridge casting mold is provided, as shown in Figures 1 to 3, hollow fiber membrane cartridge casting mold comprises die main body 10 and built-in circle 20, wherein, die main body 10 is provided with charge groove 11, and described built-in circle 20 can be positioned over described bottom, forms stairstepping pour into a mould chamber with described charge groove 11.Preferably, described charge groove 11 is circular trough, and described built-in circle 20 is circular, and the internal diameter of the external diameter of described built-in circle 20 and described charge groove 11 matches.Hollow fiber membrane cartridge casting mold is owing to have employed this kind of structure, when carrying out filter core cast, by changing the internal diameter of different built-in circle 20 to change the packed density of film silk, change filter core by the height changing different built-in circle 20 and enter glue height, thus on the basis not changing die main body 10, prepare different packed densities flexibly, enter the hollow fiber membrane cartridge of glue height, operability is flexible, can save repeatedly mold expense, and water the filter core form uniform specification outpoured.
Preferably, described built-in circle 20 has elasticity, forms tight fit to make built-in circle 20 with die main body 10.
Preferably, the Hydrophobic organic materials that described die main body 10 and described built-in circle 20 adopt surface energy low is prepared from, to solve the problem of demoulding difficulty after resin solidification.
The hardness of described die main body 10 and described built-in circle 20 is selected in the machinable scope of material, the requirement of mechanical strength final with die main body 10 and the ease common decision of the demoulding, the hardness of described die main body 10 and described built-in circle 20 is preferably 30 ~ 90 degree, more preferably 50 ~ 80 degree.
Preferably, the material of described die main body 10 is silicon rubber, fluorubber or fluoroplastics.The material of described built-in circle 20 can select silicon rubber that hardness is large or the just larger fluoroplastics of hardness own.
Hollow fiber membrane cartridge casting mold of the present invention, owing to have employed said structure, has following beneficial effect:
1, by regulating the internal-and external diameter of built-in circle, height size can reach the object regulating filter core end face glue ring size, packed density, filter core to enter the filter core preparation parameters such as glue height, operability is flexible, repeatedly mold expense can be saved, and water the filter core form uniform specification outpoured;
2, the Hydrophobic organic materials that die main body 10 and built-in circle 20 adopt surface energy low is prepared from, and uses the easy demoulding;
3, this mould uses simple and easy, feature easily.
In another embodiment of the present invention, a kind of hollow fiber membrane cartridge pouring procedure is provided, comprises the steps:
Step S1, in the charge groove 11 of described die main body 10, pour into appropriate casting glue.
Step S2, the end face hollow-fibre membrane tow that shutoff is concordant in advance to be inserted in described built-in circle 20.
Step S3, after the casting glue standing and defoaming in described charge groove 11, one end of built-in circle 20 is had to embed in described charge groove 11 on hollow-fibre membrane tow hoop.
Step S4, be inserted in filter-core shell in the outside of described hollow-fibre membrane tow, make filter-core shell be placed in the upper surface of described built-in circle 20, thus realize pouring operation.After casting glue solidification, filter core and casting mold are peeled off, completes the casting process of hollow fiber membrane cartridge one end.
The conveniently demoulding, before carrying out resin-cast, charge groove 11 inwall and built-in circle 20 surfaces externally and internally need first uniform application last layer lubricant, lubricant comprises vaseline, grease, cup grease, releasing agent (based on medical ventolin, but being not limited to this).
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
