Abstract

A length-adjustable adapter device (100) for connecting a plastics melt filtering device (200) to a pipeline (300), having at least a housing connection element (10) which has at least one inner flow duct (13) in a pipe extension (12) which is provided with an external thread (14), an adjusting ring element (20) having an internal thread (24) for receiving the external thread (14) of the pipe extension (12) and a line connection element (30) for connecting to the pipeline (300) with a line ring flange (31) and with a pipe extension (32) having an inner flow duct (33). The line ring flange (31) is rotatable in a receiving groove (23) of the adjusting ring element (20) and is fixed in a form-fitting manner against axially acting forces.

Claims

1. A length-adjustable adapter device for connecting a plastics melt filtering device to a pipeline, comprising:

a housing connection element comprising at least one inner flow duct in a pipe extension having a reduced outside diameter, said pipe extension being provided over at least part of the length thereof with an external thread;

an adjusting ring element comprising an internal thread configured to receive the external thread of the pipe extension of the housing connection element; and

a line connection element configured to connect to the pipeline with a line ring flange and with a pipe extension having an inner flow duct,

wherein the line ring flange of the line connection element is rotatable in a receiving groove of the adjusting ring element and is fixed in a form-fitting manner against axially acting forces, and

wherein the pipe extension of the line connection element is partially pushed into the flow duct of the housing connection element.

2. The adapter device of claim 1, wherein the line ring flange has a multiplicity of passage bores or threaded bores.

3. The adapter device of claim 1, wherein the adjusting ring element has a ring flange with a multiplicity of passage bores or threaded bores.

4. The adapter device of claim 1, wherein the adjusting ring element is formed from two half elements, wherein the receiving groove for the line ring flange is formed in the plane of separation of the half elements.

5. The adapter device of claim 1, wherein the adjusting ring element is provided with at least one heating means.

6. The adapter device of claim 5, wherein the at least one heating means is formed by a heater band.

7. The adapter device of claim 1, wherein the housing connection element comprises a housing adapter ring with a multiplicity of passage bores or threaded bores.
