摘要： The invention relates to a device for circulating a liquid received in a container, in particular for circulating wastewater received in a basin, comprising a hyperboloid or truncated cone-shaped stirring element (1) which is attached to a vertical shaft. Multiple transport ribs (T1... T8) which run from the circumferential edge (UR) in the direction of the shaft are provided on an outer face (A) of the stirring element (1), and a central line (M1... M8) between two adjacent transport ribs (T1... T8) is defined by points having the same minimum distance to each ridge line (K1... K8) of the two adjacent transport ribs (T1... T8). A through-opening (D1... D8) in the stirring element (1) is provided between the two transport ribs (T1... T8), and a through-opening surface which is delimited by the edge of the through-opening (D1... D8) has a geometric center of gravity (S1... S8). The aim of the invention is to improve the efficiency of the device. According to the invention, this is achieved in that the geometric center of gravity (S1... S8) of the through-opening surface is located in a region between the central line (M1... M8) and the ridge line (K1... K8) of one of the two transport ribs (T1... T8).

摘要： The invention relates to a stirring device for activated sludges comprising a stirring body (2) attached to a shaft (1) and having a hyperboloid wall (3), further comprising an air supply line (5, 8) for supplying air to a funnel-like recess (6) formed on a bottom of the stirring body (2). In order to improve the entry of air into the fluid medium surrounding the stirring body (2), the invention provides for an opening of the recess (6) formed on the bottom be covered with a covering element (7) such that an annular gap (10) having a predetermined width remains uncovered between an outer circumferential surface (9) of the stirring body (2) and the covering element (7) and for the air supply line (8) to be guided coaxially through the cover element (7) relative to the shaft (1).

摘要： The invention relates to a stirring device for activated sludges comprising a hyperboloid stirring body (2) attached to a shaft (1), wherein a plurality of transport ribs (3) are provided on the top (O) of the stirring body (2) running toward the circumferential boundary (UM) thereof, wherein the transport ribs (3) have an oblique course, at least in sections, relative to a radial direction, and wherein an oblique position of the transport ribs (3) is selected such that, when the stirring body (2) rotates in a predetermined rotational direction (R), a flow is generated that is directed radially outward away from the circumferential boundary (UM) of the stirring body (2). In order to improve the efficiency of the stirring device, the invention proposes that at least one propeller (6) be attached to the shaft (1) that, when the stirring body (2) rotates in the rotational direction (R), generates a flow (A) directed toward the top (O) of the stirring body (2).

摘要： The invention relates to a drive device for the immersed operation below a surface of a liquid (F), particularly for the immersed operation in a clearing basin, having a drive shaft (5) guided out of a housing, wherein the drive shaft (5) is guided through an axial face seal (12, 13) received in a sealing chamber (10) for sealing the housing against penetrating liquid. In order to improve the service life of the seal, the invention provides that a line (22) is connected to the sealing chamber (10) for receiving an oil supply and is guided to above the surface of the liquid (F).

摘要： The invention relates to a decanter for separating a supernatant protruding from a sewage sludge in a sludge tank (1) having a withdrawal device (4) attached to a first end (El) of a pivot-mounted discharge pipe (3), wherein for discharging the supernatant flowing through the discharge pipe (3) near a second end (E2) opposite of the withdrawal device (4) a flexible hose (14) is provided, which is connected to a connecting piece (13) that is firmly mounted to the base relative to the pivoting bearing. In order to improve the robustness of the decanter, the invention provides that the discharge pipe (3) is received at its second end (E2) pivoting around a pivoting axis (A) in a pivoting bearing (2) having two bearing blocks (17) supported on a base.
