The present disclosure relates to a mixing assembly for a fluid mixing system. The mixing assembly includes a first rotational assembly having a first casing and a first hub rotatably mounted to the first casing, a second rotational assembly having a second casing and a second hub rotatably mounted to the second casing, an elongated member having a first end coupled with the first hub and an opposing second end coupled with the second hub, and one or more impellers secured to the elongated member.

A device aerates a drinkable liquid inside a handheld container. An aerator is detachably mounted on the container in a mounted position. The aerator has an aerator portion that extends into the liquid and that is held adjacent an interior surface of a side wall of the container in the mounted position. The aerator portion has a multitude of turbulence-inducing agitating elements, such as pores, through which the liquid in the container flows to, and impacts against, the interior surface of the side wall of the container, and mixes with ambient air in the container, when the container is manually swirled to aerate the liquid.

The invention relates to a horizontal agitator for producing a flow in a clarifier, a submersible motor (1) and a propeller (3) drivingly connected thereto forming an assembly unit (M), wherein a receiving portion (A) for removably attaching the assembly unit (M) is provided and can be supported on the bottom (Bo) of the clarifier, and wherein a guide for guiding the assembly unit (M) along a substantially vertical movement path between a surfacing position above a maximum nominal sewage level (N) defined for the clarifier and the receiving portion (A) is provided. In order to improve the efficiency of the horizontal agitator and to reduce complexity of manufacture, the guide is formed by at least one first cable (S) extending between the surfacing position and the receiving portion (A).

A tool for resisting rotation of a bucket of the type having a handle carried on a support wire is provided. The tool includes a handle engaging portion configured for attaching or engaging with the handle of the bucket, and a step plate coupled with the handle engaging portion and configured for resting against a surface of the ground. The handle engaging portion and the step engaging portion are configured to extend at generally right angles from each other. In operation, the handle engaging portion is engaged with the handle of the bucket, and the step plate is positioned on the ground, and a user steps on the step plate during mixing of materials contained within the bucket.

An aerator accessory has a handle having a main body and a plurality of connecting joints surrounding the main body, a top end and a bottom of each connecting joint respectively connected to a socket with different diameters. Each socket has an opening end and an inner sidewall, and one opening end of at least one of the sockets has a first fastening portion with a plurality of engaging teeth disposed evenly around the opening end. One inner sidewall of at least one of the sockets has a second fastening portion with two opposite parallel tangent planes. One inner sidewall of at least another socket has a third fastening portion comprising at least two fastening grooves on the inner sidewall.

An aeration device includes a pipe, connection members and a first connection unit which is connected to the connection member. The first connection unit includes a first connector, a first connection part, a one-way member, a second connector, a turbine unit and a shell. When air enters into the pipe, the shell guides the air and liquid in the pound into the turbine unit via the second and third rooms so as to increase the mixing feature of the air and the liquid in the pound.

A bucket holding and tipping device has a system of one or more combination handle/foot plates affixed to the outside of a bucket.

A fluid mixing system includes a flexible bag having an interior surface bounding a compartment. A retainer is coupled to the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag. An elongated tubular connector has a first end coupled to the flexible bag and an opposing second end projecting into the compartment thereof. An impeller is disposed within flexible bag and is coupled with the tubular connector. A steady support is mounted on the second end of the tubular connector and terminates at a distal nose, the distal nose being freely disposed within the retention cavity of the retainer so that the steady support can rotate within the retention cavity relative to the retainer.
