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

1. A high efficiency stripper nozzle, made up of at least one body with a through hole (10) configured to be connected to the through hole (20) of another stripper nozzle, guide, or nozzle (2), characterized in that it comprises several radial channels (18, 19) that pass through the stripper nozzle from the perimeter zone to the hole (10) at its entrance zone.

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

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

4. The stripper nozzle according to claim 1, wherein the hole (10) comprises a cone-shaped entrance.

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

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

7. The stripper nozzle according to claim 6, wherein the radial channels (18, 19) are made up of sections with different angles () with respect to the axis (4) of the hole (10).

8. The stripper nozzle according to claim 5, wherein one of the pieces of the stripper nozzle houses other pieces of the stripper nozzle.

9. The stripper nozzle according to claim 5, wherein it comprises at least two pieces that are symmetrical with respect to one of the planes coinciding with the axis (4).

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0021] The aforementioned figures, according to the adopted numbering, show a preferred embodiment of the invention, which comprises the parts and elements that are indicated and described in detail below.

[0022] As shown in FIG. 1, one possible embodiment of the present stripper nozzle is divided into a set of three pieces (11, 12, 13), arranged in series and attached to a nozzle (2), whose through hole (20) is connected to the through hole (10) of the stripper nozzle, in this case with a cone-shaped entrance.

[0023] In this embodiment, the internal contact walls (14, 15, 16, 17) between the pieces (11, 12, 13) have an angled cross-section with respect to the axis (4) of the hole (10), with a conical angle () of 15. The walls comprise gaps such that between them, radial channels (18, 19) are formed, which emerge, on one hand, at the entrance of the through hole (10), and on the other, are connected to the opening (21) located on one of the longitudinal faces of the nozzle (2) by means of a perimeter channel (3), which, in this case, the internal pieces (12, 13) share with the nozzle (2).

[0024] In this embodiment, as shown in FIG. 1, the means for attaching the stripper nozzle (1) to the nozzle (2) are made up of several holes (4) in the corners of the front face for threading screws (not shown in the figure).

[0025] The details, shapes, dimensions, and other accessory elements, as well as the materials used in the fabrication of the present stripper nozzle may be substituted as needed with others that are technically equivalent and that are not at variance with the essential nature of the invention or the scope defined by the claims included below.
