Abstract: A method for handling a product, in particular a viscous, pasty product, with at least one rotating shaft (3, 11) in a product space (5), a driving spindle (11) of the shaft (3) is mounted and sealed outside the product space (5) in a housing consisting of a plurality of parts (7, 8, 12). The sealing is brought about by at least two seals (2, 4), wherein a dynamic seal (2) follows an eccentric movement of the shaft (3) and takes on dynamic sealing of the rotating shaft (3), while another seal (4) compensates for an eccentric movement of the shaft (3) in relation to the housing by plastic or elastic deformation and therefore prevents a leakage between the housing part (12), which moves eccentrically, and a rigid housing (10).

Abstract: A kneader for carrying out mechanical, chemical and/or thermal processes, comprising at least two shafts, which rotate in a manner that is parallel to the axis and which are situated inside a housing having an inner wall. Kneading bars, which follow one another in a direction of rotation and in an axial direction of the shafts and which extend along the inner wall of the housing and in the direction of the shafts or diagonal thereto, are located on the shafts while being mounted on a supporting element. The paths of the kneading bars on both shafts overlap at least partially and, during rotation, the kneading bars on one shaft engage between the supporting elements on the other shaft. The supporting elements are of different thicknesses and are arranged in succession in a direction of rotation (X) on the shaft while being situated on and/or in a radial plane (E).

The packing box comprises at least a sealing casing which presses on at least a compression packing. The sealing casing is pushed against the compression packing parallel to the axis of the shaft with adjustable pressure.

Abstract: The invention relates to a mixer-kneading device for carrying out mechanical, chemical and/or thermal processes, consisting of mixing elements (A, R) disposed on a shaft (2, 3), extending approximately in the longitudinal direction of the shaft (2, 3) or being somewhat inclined and comprising at least one scraping edge (14, 18, 21). Said mixer-kneading device is characterised in that clearance angles (w1-w6) are formed, respectively, in a direction leading away from the scraping edge (14, 18, 21) and which is opposite to the direction of movement of the mixer element.

In this case, mixing arms (14) of different configurations engage in the open space (toric space 12) from the shaft (2).

Abstract: In a kneader mixer for the thermal or chemical treatment of products in liquid, pasty and/or powdered form within a housing (1), a kneader shaft (20) which is provided with blade elements (25) and rotates around an axis of rotation (A) is arranged. Between the blade elements (25) there are kneading-support elements (27, 43) having in each case a foot (32) fastened on the housing. The blade element(s) (35) is (are) arranged in blade planes (E) perpendicular to the kneader shaft. In this connection, the foot (32) of the kneading-support element (27, 43) also lies in the plane (E) of the blade element(s) (25).

Abstract: In a mixing kneader for the mechanical and/or thermal treatment of products, there is a shaft (16) arranged in a housing (1), on which shaft disk segments (21) are avoided distributed in the axial direction. In the kneading spaces (24) between the disk segments (21) there are fixed kneading counter-elements (27), which clean the disk segments (21) and shaft (16) and comprise a section (30), running close to the disk segments (21), and an arm (31), running close to the circumferential surface (37) of the shaft (16). In order that the section and the arm can give way to excessive product encrustations on the shaft, a center line (N) of the section (30) close to the disk segments (21) is to run at an inclination, in the direction of rotation (Z) of the shaft (16), corresponding to a secant through the shaft (16). Something similar also applies to the center line (O) of the arm (31) and to a leg (28) adjoining the section (30) at the other end from the arm (31).

Abstract: For the separation of sulfur from a sulfur/alkaline solution suspension, the suspension is heated to a temperature above the melting temperature of the sulfur and is introduced under pressure into a separating tank 1, containing a separating chamber 8, alkaline solution chamber, and sulfur chamber 12. From the separating tank, settled liquid sulfur is continuously withdrawn, on the one hand, via conduit 16 and alkaline solution is continuously withdrawn, on the other hand, via conduit 9. In order to provide a system having little susceptibility to trouble, the separating chamber and alkaline solution chamber are operated in the flooded mode, thereby avoiding the necessity for a steam blanket therein.
