摘要:
Es sollen solche das Mischen bewirkende Misch-Schikanen (17,18) geschaffen werden, die einerseits eine intensive Vermischung ergeben und andererseits gewährleisten, dass die miteinander vermischten Medien möglichst vollständig durch das Mischgerät hindurch und aus dem Auslass (6) gefördert werden. Das ist besonders dann wichtig, wenn die Medien ein Kleber und ein Aushärtungs-Beschleuniger sind. Hierzu werden die Misch-Schikanen als Stifte (17,18) ausgebildet, die eine kreis-, oval- oder tropfenförmige Querschnittsfläche aufweisen. Es ergeben sich hierdurch keine Stauflächen für die strömenden Medien und eine möglichst wirbelfreie Strömung

The invention relates to a device for mixing and transporting a polymer melt. Said device consists of a mixer and a transporting means. The mixer comprises a hollow cylindrical mixing shaft (external shaft) and an internal mixing shaft (internal shaft). The hollow cylindrical mixing shaft is arranged such that it encloses the internal mixing shaft. Both mixing shafts penetrate into a mixing chamber in a protruding manner. On the face end a passage is formed between the wall of the mixing chamber and the free end of the external shaft so that the mixing chamber is divided into an inner mixing chamber (internal chamber) and an outer mixing chamber (outer chamber) which are connected via the passage. The melt inlet and melt outlet are positioned in such a way that the melt flow passes through the inner chamber and the outer chamber in opposite directions of flow.

Disclosed is a process for continuously mixing two liquid components, one of said liquid components being a two-liquid curing type resin, which process comprises continuously supplying one liquid component under stirring into a mixing container (10) and pouring the other liquid component into said container by pushing open a needle (32) forcibly provided to a check valve (30), wherein said needle (32) is pushed open with a non-curing liquid, and thereafter a curing liquid is poured into said mixing container. According to the present invention, when, for example, a polyamide acid and a curing agent are caused to mix and react with each other, a transparent polyimide mixed uniformly is obtained and high quality molded articles of polyimide are provided therefrom.

A device for mixing at least two fluid to pasty substances has a housing (2) with at least two openings (5, 6) for feeding the substances and with a discharge opening (8), a mixing element (3) which can rotate in the housing (2), which mixing element (3) can be displaced in the direction (17) of its axis (7) in relation to the housing (2) in order to adjust the size of a gap (18) between a conically tapering part (14) of the mixing element (3) and a likewise tapering region (15) of the housing (2) in order to adjust the shear rate in the region of the gap (18). The mixing element (3) has a region (9) in which annular ribs (11) are provided which project from the mixing element (3) and which engage between adjacent annular ribs (12) which project from the inner surface (10) of the housing (2).

Disclosed is a continuous two-liquid type mixer comprising: a cylindrical container (10) having a liquid inlet (14) at one end and an outlet (16) at the other end; rows of stationary stirring blades (18,20) on the inside of said cylindrical container (10) protruding substantially radially on the same periphery; a rotor (22) to rotate about the same axis and housed in said cylindrical container; and rows (26) of rotary stirring blades (24) on the outside of said rotor (22) protruding substantially radially on the same periphery in an alternate relation with said rows of stationary stirring blades (18,20) on the inside of said cylindrical container, wherein at least one liquid injection inlet (28) is provided on either or both of said stirring blades on said liquid inlet side. According to the present invention, even highly viscous liquids can be mixed quickly and uniformly and troubles caused by ununiform mixing can be solved without fail.

The present invention discloses a stirring-type mixer comprising a cylindrical container (10), a rotor (22) housed in the cylindrical container and stirring blades (18,24) attached to either of the cylindrical container or the rotor or the both, for stirring and mixing a plurality of fluid materials of different kinds fed into the aforementioned cylindrical container, while said cylindrical container and the rotor are rotated relatively, wherein a cooling means (32,36) is provided inside the aforementioned rotor and fluid materials are cooled thereby in the cylindrical container. The mixer has the capability of releasing the heat of reaction and Joule's heat out thereof and ensures against thermal deformation of the liquid material as well as shortening of its pot life.
