Abstract

A device for division of a non-Newtonian liquid, for example a molten synthetic material, flowing through a passage (1, 21), and comprising a flow-conditioned viscosity decreasing outward in cross section in flow through a T-shaped passage branching (T) deflecting and dividing the liquid flow. In a first embodiment of the device, before the end of the supply passage (1), a partition (11) is installed in the passage branching (T) dividing the liquid counterflow from the supply passage (1) into two halves, the angular position of the partition (11) assuming a setting adapted to the distribution of the differentially viscous components of the liquid in the supply passage (1). In a second embodiment of the device, in the passage branching (T), a deflector (23) is installed, so fashioned that essentially the central (viscous) component of the liquid from the supply passage (21), prior to its deflection into the discharge passages (22a, 22b), is divided into two components and these are so deflected that the two components preferably flow diametrally towards each other in the region ahead of the discharge passages (22a, 22b).

Claims (16)

  1. [Claim 1]A device for dividing a non-Newtonian liquid material flowing through a passage (1), the material having a flow-conditioned viscosity decreasing outward in cross-section in flow through a substantially T-shaped passage branching (T) deflecting and dividing the liquid flow, comprising a partition (11) positioned adjacent the end of the supply passage in the passage branching (T) which divides the liquid flowing counter from the supply passage segment (1) into two halves, the angular position of the partition (11) having a setting adapted to the distribution of the differentially viscous components of the liquid In the supply passage segment (1), wherein the liquid flowing into the said discharge passages does not have substantial distribution of the differentially viscous components of the liquid.
  2. [Claim 2]The device according to claim 1, wherein the partition (11) is adjustable in its angular position.
  3. [Claim 3]The device according to claim 1 wherein the partition (11) is positioned in the passage branching (T) by means of a partition plug (10) to which the partition (11) is attached by way of a bore (12) in the passage branching (T).
  4. [Claim 4]The device according to claim 2 wherein the partition (11) is positioned in the passage branching (T) by means of a partition plug (10) to which the partition (11) is attached by way of a bore (12) in the passage branching (T).
  5. [Claim 5]The device according to claim 3, wherein the partition plug (10) at a first end adjacent the supply passage segment (1) has a dome-shaped recess (16) in which the partition (11) is fastened.
  6. [Claim 6] The device according to claim 5 wherein said dome-shaped recess (16) is bored open In the direction of the discharge passages (2a, 2b).
  7. [Claim 7] The device according to claims 3 wherein to secure the lengthwise position of the partition plug (10), a screw plug (14) is screwable into the bore (12) at the back of the partition plug.
  8. [Claim 8] The device according to claim 4 wherein to secure the lengthwise position of the partition plug (10), a screw plug (14) is screwable into the bore (12) at the back of the partition plug.
  9. [Claim 9] A device for dividing a non-Newtonian liquid material flowing through a passage (21), the liquid material having a flow-conditioned viscosity decreasing outward in cross section in flow through a substantially T-shaped passage branching (T) deflecting and dividing the flow of liquid, comprising a deflector (23) positioned in said passage branching (T) for dividing the central (viscous) component of the liquid material from the supply passage segment (21) prior to its deflection into the discharge passages (22a, 22b) into two components, said two components being deflected in the region ahead of the discharge passages (22a, 22b) and preferably flowing diametrally towards each other wherein the liquid flowing into the discharge passages (22a, 22b) does not have substantially asymmetrical distribution of the differentially viscous components of the liquid.
  10. [Claim 10] The device according to claim 9, wherein the flow directions of the two components flowing towards each other run substantially perpendicular to the longitudinal axes of the discharge passages (22a, 22b).
  11. [Claim 11] The device according to claim 9, wherein the deflector (23) projects into the end of the supply passage (21) and beginning from the blade (24), at first widens perpendicular to the latter and then narrows again.
  12. [Claim 12] The device according to claim 10, wherein the deflector (23) projects into the end of the supply passage (21) and beginning from the blade (24), at first widens perpendicular to the latter and then narrows again.
  13. 13 [Claim 13] The device according to claim 11, wherein the deflector (23) is positioned to not contact the wall of the supply passage segment (21).
  14. [Claim 14] The device according to claim 11, wherein the deflector (23) is secured to the passage branching (T) by a web (27) present at its in flow direction posterior end.
  15. [Claim 15] The device according to claim 13 wherein the deflector (23) is secured to the passage branching (T) by a web (27) present at its in flow direction posterior end.
  16. [Claim 16] The device according claim 9 wherein the shape of the deflector (23) proceeds from a cylinder provided with the said blade (24) at its anterior end, behind this a constriction emanating from two sides (25) running essentially parallel to the blade, forming the said web (27), and then continuing as a cylindrical segment (31) with the aid of which the deflector (23) is insertable and fastenable in the bottom of the passage branching (T) from without through a bore in the bottom thereof.
