Abstract
The utility model provides a voltage -sharing formula spinneret cap subassembly has pressure distribution chamber, filter cloth, spinneret, and the connection of pressure distribution chamber is being spouted between a thick liquids export and the filter cloth, lets thick liquids get into pressure buffers of formation between the filter cloth. This pressure distribution chamber is the horn mouth shape, has circular feed inlet, loudspeaker face and circular discharge gate, and the diameter of feed inlet is the 12 -15 of discharge gate diameter. The utility model discloses a filtering material non -deformable, filtering quality is better, can improve the quality of spouting the silk.
Description
Technical field
The utility model relates to a kind of spinneret cap for adopting during chemical fibre spinning.
Background technology
At present, the slurry inlet of general dry spinning spinneret cap, and distance between filtering material or spinneret cap face is less, and almost without excessive pressure or buffer area, high-pressure material is not easily even in the pressure distribution in filtering material and spinneret cap face.Easily cause filtering material to be out of shape, affect filter quality; Indivedual spinneret orifice spray silk is weak or unable, easily produces oblique silk, the silk that wafts, drips slurry etc., causes the failure of spray silk.
Number of patent application be 901095494 file provide a kind of spinneret cap of producing filaments from flowable material, in a spinneret cap, the spinnerets being provided with spray silk capillary and hole forms many platelets, be pressed in the stepped hole of a high rigid support plate again, the thickness of this support plate and the thickness of capillary plate have nothing to do, and the composition material of this support plate can be quite hard material and can not be restricted to the density of capillary.For this purpose, platelet can be made up of softer material.Increase and the installation of this platelet connect the flowing easily hindering spinning slurry, also may have adverse effect to shaping speed.
Number of patent application be 2003201124066 file provide a kind of viscose filament yarn deformed hole spinnerette packs, a kind of viscose filament yarn deformed hole spinnerette packs, belong to technical field of textile machine, for solving the spray silk problem of production three leaf viscose filament yarn.It is made up of spinneret cap, spinning head, filter cloth and pad, the cross sectional shape of spinning head is thin-walled " ∩ " shape, uniform spinneret orifice on concave surface, its special feature is: the cross sectional shape of described spinneret orifice is trilobal, and the breadth length ratio of the every leaf size in exit in hole is 1: 4 ~ 10.This utility model technology reduces the spacing of filter cloth and spinning head, easily causes slurries to stick with paste cap blocking spinneret orifice, causes the Quality Down of tow.
Summary of the invention
Utility model object: a kind of even pressure type spinneret cap assembly that can improve slurries filter effect and spinning quality is provided.
Utility model technical scheme:
The even pressure type spinneret cap assembly that the utility model provides, is connected between spray silk slurry outlet and spray silk path, has pressure distribution chamber, filter cloth, spinnerets.Pressure distribution chamber is connected between spray silk slurry outlet and filter cloth, the effect in pressure distribution chamber is to allow slurry before entering filter cloth, form a pressure buffer district, high-pressure material pressure before reaching spinnerets is disperseed rapidly, filter cloth is formed more uniform pressure, thus reduce the problems such as oblique silk appears in the tow sprayed from spinnerets, the silk that wafts, a slurry, improve the quality of spray silk.
This pressure distribution chamber is horn mouth shape, has circular charging aperture, loudspeaker face and circular discharging opening, and loudspeaker face can be round table surface shape, the spherical shape of local or the ellipsoidal shape of local.
The size of circular discharging opening is not more than the area of filter cloth, and the size of circular charging aperture is less than the size of circular discharging opening, and the diameter of circular charging aperture is the 1/2-1/5 of circular discharging opening diameter, is preferably 1/3.
The height in pressure distribution chamber is generally not more than the distance between filter cloth to spinnerets.
Even pressure type spinneret cap assembly can adopt copper material or stainless steel etc. and slurry that any chemical reaction does not occur and not produce the material manufacture of electrostatic.
Spinneret cap filter cloth can adopt nonmetal weaving material, nonmetal nonwoven material, metal sintering filter disc, metal knitted filter screen or ceramic post sintering filter disc etc. and slurry that any chemical reaction, dissolving or material that is swelling and that do not produce electrostatic do not occur and make, and can be used alone or combinationally use.
Beneficial effect:
Filter cloth of the present utility model and spinnerets are subject to the pressure ratio of slurry comparatively evenly, and filtering material is not yielding, and filter quality is better, and the quality of spray silk is higher.The utility model does not relate to the profile variation of spinneret cap assembly, newly-built equipment or the expense transformed on original production line lower.
Accompanying drawing explanation
Fig. 1 adopts a cross-sectional structure schematic diagram of the present utility model;
In figure: 1, slurry outlet; 2, pressure distribution chamber; 3, pad; 4, filter cloth; 5, spinnerets; 6, circular charging aperture; 7, loudspeaker face; 8, circular discharging opening.
Detailed description of the invention
Even pressure type spinneret cap assembly as shown in Figure 1, be connected between spray silk slurry outlet 1 and spray silk path, there is filter cloth 4, spinnerets 5, filter cloth there is pad, separately there is pressure distribution chamber 2, pressure distribution chamber 2 is connected between spray silk slurry outlet 1 and filter cloth 4, in horn mouth shape, be made up of circular charging aperture 6, loudspeaker face 7 and circular discharging opening 8, the size of circular discharging opening 8 is not more than the area of filter cloth 4, the size of circular charging aperture 6 is less than the size of circular discharging opening 8, and the diameter of circular charging aperture 6 is the 1/2-1/5 of circular discharging opening 8 diameter.Loudspeaker face 7 is round table surface shape, and the height in pressure distribution chamber 2 is not more than the distance between filter cloth 4 to spinnerets 5.
