Abstract

A heat treatment device for a thermal treatment of a workpiece is provided with a housing that houses a chamber for accommodating the workpiece for the thermal treatment. A first roller supports the workpiece and moves the workpiece in a moving direction. A first brush seal is provided, wherein the first roller and the first brush seal are arranged relative to each other such that a first side of the workpiece contacts the first roller and a second side of the workpiece that is opposed to the first side contacts the first brush seal such that the first roller and the first brush seal then seal at least a first section of the chamber from a second section of the chamber.

First claim

a first roller ( 110 ) configured to support the workpiece ( 101 ) and move the workpiece ( 101 ) in a moving direction ( 105 );
a first brush seal ( 111 ), wherein the first roller ( 110 ) and the first brush seal ( 111 ) are arranged relative to each other such that a first side of the workpiece ( 101 ) contacts the first roller ( 110 ) and a second side of the workpiece ( 101 ), wherein the second side is opposed to the first side, contacts the first brush seal ( 111 ) such that the first roller ( 110 ) and the first brush seal ( 111 ) seal at least a first section (I) of the chamber ( 103 ) from a second section (II) of the chamber ( 103 ).

2. The heat treatment device ( 100 ) according to claim 1 , further comprising a driving unit operatively connected to the first roller ( 110 ) to drive the first roller ( 110 ) such that the first roller ( 110 ) drives the workpiece ( 101 ) along in the moving direction ( 105 ).

3. The heat treatment device ( 100 ) according to claim 1 , wherein the first roller ( 110 ) is adjustable relative to the first brush seal ( 111 ) such that a distance between the first roller ( 110 ) and the first brush seal ( 111 ) is adjustable.

4. The heat treatment device ( 100 ) according to claim 1 , wherein the first roller ( 110 ) is adjustable in the moving direction ( 105 ).

5. The heat treatment device ( 100 ) according to claim 1 , wherein the first brush seal ( 111 ) is adjustable relative to the first roller ( 110 ) such that a distance between the first roller ( 110 ) and the first brush seal ( 111 ) is adjustable.

6. The heat treatment device ( 100 ) according to claim 5 , further comprising a pretensioning device ( 104 ) configured to pretension the first brush seal ( 111 ) relative to the first roller ( 110 ) such that the pretensioning device ( 104 ) presses the first brush seal ( 111 ) in a direction toward the first roller ( 110 ).

7. The heat treatment device ( 100 ) according to claim 1 , wherein the first brush seal ( 111 ) is adjustable in the moving direction ( 105 ).

8. The heat treatment device ( 100 ) according to claim 1 , wherein the first brush seal ( 111 ) is adjustable in the moving direction ( 105 ) and is adjustable in a direction parallel to an axial direction of a rotary axis of the first roller ( 110 ).

9. The heat treatment device ( 100 ) according to claim 1 , wherein the first brush seal ( 111 ) is adjustable in a direction parallel to an axial direction of a rotary axis of the first roller ( 110 ).

10. The heat treatment device ( 100 ) according to claim 1 , wherein the first brush seal ( 111 ) comprises brushes ( 201 ) and further comprises a brush holder ( 202 ) for holding the brushes ( 201 ).

11. The heat treatment device ( 100 ) according to claim 10 , wherein the first brush seal ( 111 ) further comprises a brush adjusting device ( 203 ), wherein the brush adjusting device ( 203 ) is configured to move the brushes ( 201 ) relative to the brush holder ( 202 ) such that a length of the brushes between the brush holder ( 202 ) and the first roller ( 110 ) is adjustable.

12. The heat treatment device ( 100 ) according to claim 1 , further comprising a dividing wall ( 114 ) dividing partially the first section (I) from the second section (II), wherein the dividing wall ( 114 ) extends from the housing ( 102 ) into the chamber ( 103 ), and wherein the first brush seal ( 110 ) is fixed to the dividing wall ( 114 ).

13. The heat treatment device ( 100 ) according to claim 1 , further comprising a second brush seal ( 112 ), wherein the second brush seal ( 112 ) contacts the first roller ( 110 ) such that the first roller ( 110 ) and the second brush seal ( 112 ) additionally seal the first section (I) of the chamber ( 103 ) from the second section (II) of the chamber ( 103 ).

14. The heat treatment device ( 100 ) according to claim 1 , further comprising two second brush seals ( 112 , 113 ) spaced apart from each other, wherein the two second brush seals ( 112 , 113 ) contact the first roller ( 110 ) such that the first roller ( 110 ) and the two second brush seals ( 112 , 113 ) additionally seal the first section (I) of the chamber ( 103 ) from the second section (II) of the chamber ( 103 ).

15. The heat treatment device ( 100 ) according to claim 1 , further comprising a second roller ( 120 ) and a third brush seal ( 334 ) arranged spaced apart from the second roller ( 12 ) in the moving direction ( 105 ), wherein the third brush seal ( 334 ) is arranged spaced apart in the moving direction ( 105 ) from the first brush seal ( 111 ), wherein the first roller ( 110 ) and the third brush seal ( 334 ) are arranged relative to each other such that the first side of the workpiece ( 101 ) contacts the first roller ( 110 ) and the second side of the workpiece ( 101 ) contacts the third brush seal ( 334 ).

16. The heat treatment device ( 100 ) according to claim 1 , further comprising:
