A multipurpose blower assembly for stimulating flows in underwater environments, which includes a lower assembly connecting to an upper assembly by a rotating shaft and a mount post for connecting the blower assembly to a supportive structure near a water body and supporting the lower assembly below and the upper assembly above the water body's surface. The lower assembly includes a lower bracket for supporting a blower motor, whereas the upper assembly includes a top plate for mounting an electrical gear motor having an output shaft connecting to the rotating shaft and a system controller having a microcontroller communicatively coupled to logic circuits for controlling operation of the electrical gear motor for rotation of the lower assembly relative to the upper assembly and a linear actuator to move upward and downward the lower bracket to effect angular positioning of the blower motor.

A guide rail assembly for a submersible machine as well as a guide rail holder for such a guide rail assembly is described herein. The guide rail holder includes a radially extending support body and an axially extending post, which is rigidly connected to the support body and which is adapted to be inserted into an end of the guide rail. An engagement head is connected to the post at a distance from the support body and has a greater radial extension than the post. The engagement head includes a radially expandable member that is adapted to be reversibly manipulated between an active state, in which the expandable member is in engagement with the guide rail, and an inactive state, in which the expandable member is disengaged from the guide rail.

An example fluid moving device for manure agitation in a pit located beneath a confinement building can include: a boom extending vertically into a pump-out wall of the pit; and a mechanism for extending horizontally into a main chamber of the pit to provide agitation. In some examples, the device can also include a self-propelled mechanism for moving along a surface.

A system and method that automatically transfer liquid manure from an intermediate holding receptacle to a lagoon involves a common pump for both agitating the liquid manure in and pumping the liquid manure from the receptacle. A pump motor, first valve, second valve and directable agitation nozzle of the pump are controlled by an electronic controller. The electronic controller switches on the pump motor, ensures that the first valve is closed and ensures that the second valve is open when the receptacle is full, directs the nozzle to at least two different locations in the receptacle to permit liquid manure to be redirected to the at least two different locations to agitate the liquid manure for a predetermined period of time, and opens the first valve after the predetermined period of time to permit pumping of the liquid manure from the receptacle to the lagoon. The system and method reduce equipment cost, equipment maintenance and the amount of operator time required to perform liquid manure transfer, while providing better agitation and more complete emptying of the receptacle in a shorter period of time.

Described is a device for granulating a powder to be granulated or a powder mixture to be granulated. The device includes at least one working vessel in which the powder to be granulated or the powder mixture to be granulated is provided, at least one mixer for mixing the powder to be granulated or the powder mixture to be granulated, at least one dosing device for granulating liquid, and at least one drive unit that includes a rotational speed range for providing a drive torque required for the mixer. The drive unit provides a uniformly high drive torque over its entire rotational speed range. Also described is a method for granulating a powder to be granulated or a powder mixture to be granulated using such a device.

A mount for a water circulator is described that is configured to control vertical adjustment and angular (or horizontal) adjustment of a water circulation assembly using independent mechanisms on the mount that mounts the water circulator to a support structure.

The invention relates to a container, in particular a fermenter for a biogas plant, wherein in the container a mixer is arranged that can be removed through an inspection opening provided in a container wall. A boom is provided for this purpose. Furthermore, the invention relates to a related method and a related use.

The invention relates to a horizontal agitator for producing a flow in a clarifier, a propeller being connected to a submersible motor which is axially offset in relation thereto, wherein the propeller and the submersible motor are designed such that a flow in a direction from the propeller towards the submersible motor is produced when the submersible motor is operated, and wherein plate-shaped flow guide elements are provided downstream of the propeller and extend in at least an axial plane that runs substantially parallel to the propeller axis. In order to improve the efficiency of the horizontal agitator, it is proposed in accordance with the invention to support the submersible motor on a bottom of the clarifier via at least two first flow guide elements.
