MAGNETIC COUPLING AND MIXING DEVICE

摘要

A device for mixing liquids in a container having an inner chamber with an enclosing wall and a bottom, an external encasement, an interspace and a transfer opening on top of the inner chamber. A mixing body located in the inner chamber comprises magnetizable material or a permanent magnet spaced from the wall. A coupling body movable in the interspace along a longitudinal axis and wall has magnetic working connection with the mixing body. The wall and the external encasement are transparent to magnetic fields. An acting permanent magnet or magnetizable material outside the external encasement, is in magnetic working connection with the coupling body. Moving the acting magnet or magnetizable material parallel to the longitudinal axis induces movement of the coupling body inside the interspace and moving the mixing body in the inner chamber, mixes liquids present in the inner chamber.

1. A device (1) for mixing liquids of different viscosity or composition within at least one container (2), each container (2) comprising:
(i) an inner chamber (3) with a longitudinal axis (4) and a chamber cross-section area (3′) that extends perpendicular to the longitudinal axis (4), the chamber cross-section area (3′) being substantially constant over at least a working part (5) of the inner chamber (3); (ii) an external encasement (6) with a bottom opening (7), the external encasement (6) being attached to the container (2) at an upper part of the latter; (iii) a wall (8) that encloses the inner chamber (3) and that is spaced apart from the external encasement (6) by an interspace (9), the wall (8) and the external encasement (6) being configured to be transparent to magnetic fields; (iv) a bottom (10) that is attached to the wall (8) and that closes the inner chamber (3) at a bottom side; and (v) a transfer opening (11) that is located at a top side of the inner chamber (3); wherein there is located within the working part (5) of the inner chamber (3) at least one mixing body (12), each mixing body (12) comprising magnetizable material (13) or a permanent magnet (13′) and defining a body cross-section area (14) that adds up to a sum of body cross-section areas (14′), the sum of body cross-section areas (14′) being less than the chamber cross-section area (3′) and the at least one mixing body (12) being spaced apart by a distance (15) from the wall (8); wherein the mixing device (1) further comprises: (vi) a coupling body (16) that is configured to be introducible into the interspace (9) via the bottom opening (7) of the external encasement (6) and that is movable in the interspace (9) substantially in direction of the longitudinal axis (4) and alongside the wall (8), the coupling body (16) comprising a first permanent magnet (17) and/or a mass of magnetizable material (18) that in each case through the wall (8) is in magnetic working connection with the at least one mixing body (12) such that moving the coupling body (16) alongside the wall (8) simultaneously induces moving the at least one mixing body (12) in the working part (5) of the inner chamber (3); and wherein the mixing device (1) further comprises: (vii) at least one acting permanent magnet (19) or acting magnetizable material (19′) that is located outside the external encasement (6) and that through the external encasement (6) is in magnetic working connection with the first permanent magnet (17), a second permanent magnet (17′), or the mass of magnetizable material (18) of the coupling body (16) such that moving the at least one acting permanent magnet (19) or acting magnetizable material (19′) at least substantially parallel to the longitudinal axis (4) of the inner chamber (3) simultaneously induces movement of the coupling body (16) inside the interspace (9), thereby moving the at least one mixing body (12) in the inner chamber (3), and thus mixing of liquids that are present in the working part (5) of the inner chamber (3) of the container (2).
