Abstract
The utility model relates to an enhancement mode hollow fiber membrane spinneret, including the spinneret body that is hollow cylinder, the cavity position of spinneret body is the feed liquid passageway, be equipped with core liquid stream way in the feed liquid passageway, the side of spinneret body is equipped with the feed liquid import, its characterized in that, core liquid stream way is equipped with 3, and the center of 3 core liquid stream ways is regular triangle and arranges. The beneficial effects of the utility model are that: textile membrane silk inside has three holes reinforcing structure, and three holes center becomes regular triangle, is favorable to improving the compressive strength of membrane silk, has higher mechanical stability, makes the improvement of membrane silk performance, and the preventing film silk breaks and leads to the raw water to be sneaked into to improve the life of membrane silk.
Description
Technical field
This utility model relates to a kind of spinneret, particularly relates to a kind of hollow-fibre membrane spinneret, belongs to technical field of membrane.
Background technology
At present, hollow-fibre membrane spinneret is single liquid stream road mode, and spun film silk is single hole arrangements, and the film silk of single hole arrangements is limited by this body structure, self-supporting ability, and use process is easily flattened, and affects overall mechanical properties and the service life of hollow-fibre membrane；Single hole arrangements film silk flux is also by certain limitation.
Utility model content
The deficiency that this utility model exists for existing hollow-fibre membrane spinneret, it is provided that a kind of enhancement type hollow fiber film spinneret.
The technical scheme that this utility model solves above-mentioned technical problem is as follows:
A kind of enhancement type hollow fiber film spinneret, including the spinnerette body in hollow cylindrical, the hollow part of described spinnerette body is feed liquid passage, core liquid stream road it is provided with in described feed liquid passage, the side of described spinnerette body is provided with liquor inlet, it is characterized in that, described core liquid stream road is provided with 3, and the center in 3 core liquid stream roads is equilateral triangle arrangement.
The beneficial effects of the utility model are: have three holes inside spinning film silk and strengthen structure, three center, holes become equilateral triangle, be conducive to improving the comprcssive strength of film silk, there is higher mechanical stability, film silk performance is made to improve, preventing film silk from rupturing causes former water to be mixed into, thus improves the service life of film silk.
On the basis of technique scheme, this utility model can also do following improvement.
Further, the outer surface of described feed liquid passage film forming end is provided with the interior convex configuration that equally distributed 3 circular arcs towards feed liquid passage central concave form, and adjacent two core liquid stream road is divided on the summit of described interior convex configuration equally with the line at feed liquid passage center.
Above-mentioned further scheme is used to provide the benefit that so that film silk appearance has three inside circular arc females, has the thinnest positive filtering surface, and permeable amount is big.
Further, the external diameter in described core liquid stream road is 0.5～3.0mm, and the summit of described interior convex configuration and the distance at feed liquid passage center are 0.8～4.0mm, and the summit of described interior convex configuration is more than the external diameter in core liquid stream road with the distance at feed liquid passage center.
