Abstract:
A sewage tank (20, 100, 200, 300) for use with a pump (12) such as a grinder pump to convey sewage. The sewage tank includes a container (21) having an upper portion (24) and a lower portion (22) defining a chamber (30) for containing the pump. The upper portion has a generally constant cross-section and the lower portion has a tapered cross-section to reduce retained sewage. The upper portion and/or the lower portion includes a plurality of vertical ribs (25) and horizontal ribs (27) defining a plurality of recessed pockets (29). The lower portion of the sewage tank may also include an outwardly extending flange (40, 110) sufficiently sized so that soil may be backfilled around the bottom of the tank to prevent the tank from floating upward out of the ground due to its buoyancy under high ground water conditions. A sewage tank having a stepped flange (110) is also disclosed.
Abstract:
The method according to the invention consists in that the valve (1) control is performed with help of the floating valve element (6), which according to needs is moved down from its open position to the close position under operation of liquid level reduction together with the floating valve element (6) floating in liquid, by means of gas supplied from the outside to the well (7) in the duration- and/or quantity-controlled manner. The device according to the invention has the well (7) connected hermetically from below with the valve (1) housing (2), in which the floating valve element (6) is situated, and the well (7) is hermetically covered with the closure head (8) to which at least one control conduit (9) is introduced, and at the same time in the housing (2) just opposite its inlet the outlet with the seat (5) is situated, on which the floating valve element (6) can be settled.
Abstract:
A grinder pump station (10) capable of having its height adjusted in the field during installation has a longitudinal tank having a substantially cylindrical non-corrugated inner wall (52) secured to a substantially cylindrical corrugated outer wall (54), a separate transition section (18) for mounting a grinder pump unit (34) within the longitudinal tank, a removable lid assembly (22) attached to the top of the longitudinal tank, and a base (32) attached to the bottom of the tank. The removable lid assembly (22) includes an electrical (76) and ventilation interface for the grinder pump unit (34) mounted in the tank, thereby facilitating adjustment of the height of the tank through variation in its longitudinal extent without interference with the electrical (76) and ventilation interface. The transition section (18) separates an upper tank portion (14) from a lower tank portion (16), preferably has a non-corrugated side wall (17), and includes a sewage inlet opening (20) and a sewage outlet opening (19) through its side wall (17).
Abstract:
Die vorliegende Erfindung betrifft einen flüssigkeitsführenden Hohlquerschnitt (1), insbesondere eine Wasser führende Leitung, wobei die Flüssigkeit (4) temperaturabhängige Volumenänderungen zeigt, insbesondere Erstarren/Gefrieren kann. Erfindungswesentlich ist dabei, dass in dem Hohlquerschnitt (1) zumindest ein Verdrängerelement (5) vorgesehen ist, welches den für die Flüssigkeit (4) zur Verfügung stehenden freien Querschnitt verringert und so die Gefahr von Frostschäden, insbesondere das Bersten des Mantels (2) des Hohlquerschnitts (1) verringert bzw. vorzugsweise gänzlich ausschließt.
Abstract:
Gegenstand der Erfindung ist eine Vorrichtung zur Überwachung und Unterstützung der Wartung einer Reinigungs- und/oder Belüftungsanlage für eine Einrichtung, die der Aufnahme und zeitweiligen Speicherung von verunreinigter Flüssigkeit dient, wobei die Reinigungsanlage ein oder mehrere Aggregate umfasst, welche in der Einrichtung befindliche Flüssigkeit ansaugen und in Form eines Strahles in die Einrichtung ausbringen. Außerdem betrifft die Erfindung ein Verfahren zur Überwachung und Unterstützung der Wartung einer Reinigungs- und/oder Belüftungsanlage mit einer solchen Vorrichtung. Im Bereich eines Luftsaugrohres (8) sind ein oder mehrere Messmittel (10) zur Überwachung des Strömungsverhalten der Flüssigkeit angeordnet.
Abstract:
In performing the method according to the invention the sewage accumulating in the transfer tank is periodically drawn away and is, in given circumstances, stirred in such a manner that the sewage is guided into the pump horizontally or downward at an acute angle to the horizontal, and the periodic pumping is performed such that when the sewage level attains a height of 1-30 cm above the pump intake opening, the electric motor is operated at a reduced sewage throughput and when, in given circumstances, the sewage level intersects the intake opening and/or the pump impeller, the electric motor is operated without sewage throughput for ventilating the sewage advantageously for at least 3 seconds, but expediently for at least 10 seconds. Stirring is performed such that the sewage is, in a vortex coaxial with the rotary axis of the stirrer agitating the sewage, first accelerated toward the stirring element and then guided along the superficies thereof and is eventually ejected in a impulse-like manner. The pump unit (4) proper comprises an electric motor (5) and a pump (6) and is arranged in the transfer tank in such a manner that its rotary axis is horizontal or is oriented at an acute angle to the horizontal and the intake opening (7) of the pump (6) is at the top.
Abstract:

The device for collecting and/or treating and carrying away liquids, multiphase systems or liquids containing lumpy materials, primarily waste water, has a container with inflow and drainage apertures, with a pump situated in the liquids chamber and with turbulence-generating elements, the pressure supports of the pump being connected with the drainage aperture of the container, the turbulence-generating element being a mechanical agitator (4) and roughened surfaces (35) in the liquids chamber being used to break up and comminute. The device for collecting and discharging multiphase media, primarily waste water, has a container fitted with a pipe for intake of waste water and a pipe for discharge of waste water and has inside the container a pump engine unit that contains an electric motor and a hydraulic unit fixed to the shaft thereof, the electric motor and the shaft being sealingly separated from each other within a common housing. The pump engine unit (1) has two hydraulic units which are fixed at one end or at the two ends of the shaft of the electric motor (2), and the shaft of the electric motor (2) is disposed horizontally or at an acute angle to the horizontal.
