Aforesaid a kind of dye liquor injector head, described spray orifice is for vertically lining up three rows, and every round is equally spaced, and the front and back round is staggered.Also can arrange the pore size distribution that is staggered front to back arbitrarily according to injector head and spray orifice size.
Aforesaid a kind of dye liquor injector head, described nozzle boss connects with welding manner with nozzle cap.Also can pass through screw attachment.
Aforesaid a kind of dye liquor injector head, the cylindrical of described dye liquor inlet tube has screw thread.Described screw thread adopts 60 ° of fastening connections of angular thread of common metric system.Also the dye liquor injector head can be connected with shower by flange.
Aforesaid a kind of dye liquor injector head, described nozzle cap is of a size of: arc length * wide=100mm * 50mm, arc diameter are 180mm; The major parameter of spray orifice satisfies following relational expression:
The willow leaf of single wicker leaf shape spray orifice is long to be 2k mm,
Willow leaf is wide to be 2k/3mm,
Total hole count n satisfies: n=23-3k, wherein, k=1～6; Preferred k=3 or 4.
Aforesaid a kind of dye liquor injector head, the described longitudinal fluting degree of depth is k mm.
As application extension, this arc shower nozzle can be adjusted size and radian, can be hemispherical or spherical shower nozzle, satisfies the needs of different spray occasions.
Beneficial effect
A kind of dye liquor injector head of the present utility model has adopted the how arc arrangement of staggered spray orifice of strip, has simplified dyeing course, has improved dyeing efficient, has avoided look flower, fringe phenomena, and DEcmc is stable less than 0.3, can guarantee fiber quality; And can reduce shower, shorten dyeing time.A kind of dye liquor injector head of the present utility model, jetting fluid wide coverage and intersection need not bigger spray pressure, and gelatine silk can not thrust, and is particularly useful for powerful little, not impact-resistant fiber.And interlock because spray nozzle is arranged, stop up the hidden danger that influences local tow colouring because of indivedual spray orifices when having eliminated single tube nozzle spray, the fiber whiting does not take place, fiber colour is even, and aberration is minimum.In addition, easy to operate, single injector head has been realized the effect of many single mouth showers, shortens dyeing time greatly, and color is switched flexibly, and the transitional fibre of generation is few, the quality problems of avoiding fiber, yarn or fabric to bring in road, back dyeing process.
