Abstract

A static mixer for mixing components of liquid reactive multicomponent compounds includes a jacket ( 1 ) having a mixing section ( 4 ). The static mixer also includes an inlet ( 2 ), an outlet ( 3 ), at least one mixing element ( 5 ) arranged in the mixing section ( 4 ) and having its outer dimensions adapted to inner dimensions of the jacket ( 1 ), and at least one chamber ( 6 ) arranged between the inlet ( 2 ) and the outlet ( 3 ) for receiving additives ( 7 ) which are added to a mixture produced in the static mixer.

Claims (26)

1. A static mixer for mixing components of liquid reactive multicomponent compounds, comprising:

an outlet ( 3 );

a jacket ( 1 ) having:

a mixing section ( 4 ); and

an inlet ( 2 );

at least one mixing element ( 5 ) arranged in the mixing section ( 4 ) and having outer dimensions thereof adapted to inner dimensions of the jacket ( 1 );

a tubular section ( 16 ) releasably connectable to and removable from the jacket ( 1 ), with the tubular section ( 16 ) including at least one chamber arranged between the inlet ( 2 ) and the outlet ( 3 ) when the tubular section ( 16 ) is connected to the jacket ( 1 ), with the at least one chamber for receiving additives ( 7 ) which are added to a mixture produced in the static mixer; and

a pair of boundary elements ( 18 , 19 ), with the boundary element ( 18 ) positioned in the tubular section ( 16 ) and arranged between the tubular section ( 16 ) and the jacket ( 1 ) when the tubular section ( 16 ) is connected to the jacket ( 1 ), and with the boundary element ( 19 ) positioned substantially adjacent to the outlet ( 3 ).

2. A static mixer according to claim 1 , wherein the at least one additives-receiving chamber is located, in a direction of flow of the mixture, downstream from the mixing section ( 4 ).

3. A static mixer according to claim 1 , wherein the jacket ( 1 ) has a surface profile with a circular cross-section.

4. A static mixer according to claim 3 , wherein the jacket ( 1 ) has an inner space with a circular cross-section.

5. A static mixer according to claim 1 , wherein the jacket ( 1 ) has at least one of circular, oval, and angular inner cross-sections, and wherein the tubular section ( 16 ) has an inner cross-section and a cross-sectional profile adapted,respectively to the inner cross-section and a cross-sectional profile of the jacket ( 1 ).

6. A static mixer according to claim 5 , wherein the jacket ( 1 ) has at least one of circular and square inner cross-section, and the tubular section ( 16 ) has a corresponding inner cross-section.

7. A static mixer according to claim 1 , wherein the tubular section ( 16 ) is releasably connectable with the jacket ( 1 ) and is fixedly connected with the outlet ( 3 ).

8. A static mixer according to claim 7 , wherein the tubular section ( 16 ) and the outlet ( 3 ) are formed as one-piece member.

9. A static mixer according to claim 1 , wherein the boundary elements ( 18 , 19 ) are formed as at least one of sieve, aperture plate, sinter plate, a fleece material filter, and a filter bag.

10. A static mixer according to claim 1 , comprising means for securing the boundary elements ( 18 , 19 ) against displacement in a forward direction.

11. A static mixer according to claim 1 , wherein openings in the boundary elements ( 18 , 19 ) are permeable for the mixture but are not permeable for not yet dissolved or dispersed additives.

12. A static mixer according to claim 11 , wherein the openings have a diameter from 0.2 mm to 2 mm.

13. A static mixer according to claim 12 , wherein the openings have a diameter from 1 mm to 1.5 mm.

14. A static mixer according to claim 1 , wherein at least one mixing element ( 5 ), which is one of carries the additives ( 7 ) to-be-added to the mixture on a surface thereof and consists of the additives ( 7 ), is arranged in the additives-receiving chamber.

15. A static mixer according to claim 1 , wherein the at least on additives-receiving chamber is one of carries the additives ( 7 ) to-be-added to the mixture on an inner surface thereof and consists of the additives ( 7 ).

16. A static mixer according to claim 1 , further comprising means for securing the mixing element ( 5 ) against rotation in the jacket ( 1 ).

17. A static mixer according to claim 1 , further comprising thread means ( 20 , 21 ) for releasably connecting the tubular section ( 16 ) with the jacket( 1 ).

18. A static mixer according to claim 1 , wherein the jacket ( 1 ), the mixing element ( 5 ), and the boundary element ( 18 , 19 ) is formed of at least one of glass, plastic material, and metal.

19. A static mixer according to claim 1 , wherein the thread means ( 17 ) is provided at the inlet ( 2 ) of the jacket ( 1 ) for releasably connecting the static mixer to an outlet of an ejector apparatus containing components of a fluid reactive multicomponent compound to-be-produced in the mixer.
