High efficiency stripper nozzle

Abstract

A high efficiency stripper nozzle, with a through hole configured to be connected to the through hole of another nozzle, guide, or nozzle, which comprises several radial channels that pass through the nozzle from the perimeter zone to the hole at its entrance zone. The nozzle may be divided into several pieces which can be connected together in a removable way and replaceable, which may form the radial channels between them with different sections and angles with respect to the axis of the hole. The radial channels may contact externally with an opening located on one of the surfaces of the nozzle or on one of the surfaces of the nozzle to which the nozzle is connected.

Claims

2. The stripper nozzle according to claim 1, wherein the stripper nozzle comprises a perimeter channel (3) that connects the plurality of radial channels (18, 19) to an opening located on one of a plurality of surface sides parallel to the longitudinal axis (4) of the through hole (10) of the stripper nozzle (1).

3. The stripper nozzle according to claim 1, wherein the stripper nozzle comprises a perimeter channel (3) that connects the plurality of radial channels (18, 19) to an opening (21) located on one of a plurality of surface sides of the another stripper nozzle (2).

4. The stripper nozzle according to claim 1, wherein the entrance zone (102) of the through hole (10) of the stripper nozzle (1) has a cone-shaped lumen.

5. The stripper nozzle according to claim 1, wherein the stripper nozzle is divided into different pieces (11, 12, 13) connected together in a removable and replaceable way.

6. The stripper nozzle according to claim 5, wherein the plurality of radial channels (18, 19) are formed by several gaps located between internal contact walls (14, 15, 16, 17) of the pieces (11, 12, 13).

7. The stripper nozzle according to claim 6, wherein the plurality of radial channels (18, 19) present different angles (a) with respect to the longitudinal axis (4) of the through hole (10) of the stripper nozzle (1).

8. The stripper nozzle according to claim 5, wherein one of the different pieces of the stripper nozzle (1) houses other ones of the different pieces of The stripper nozzle (1).

9. The stripper nozzle according to claim 2, wherein the stripper nozzle comprises at least two pieces that are symmetrical with respect to the longitudinal axis (4).

10. The stripper nozzle (1) according to claim 1, wherein the fluid led by the plurality of radial channels (18, 19) is pressurized externally to the stripper nozzle (1).

11. The stripper nozzle (1) according to claim 1, wherein the coolant/lubricant fluid flow enters through at least one radial channel of the plurality of radial channels (18, 19) and emerges towards the entrance zone (102) through one or more other radial channels of the plurality of radial channels (18, 19).

12. The stripper nozzle (1) according to claim 1, wherein the plurality of channels are situated on a tapered part of the nozzle.
