An aeration nozzle is provided, having on one end an air supply port (16a) connected to an aeration pump (13) and a waste water suction port (17) for suctioning waste water in a processing tank (3, 4), and having a micro-bubble generation unit (18), provided facing the air supply port, for mixing air supplied by the air supply port and waste water suctioned from the waste water suction port and generating micro-bubbles (9), wherein a plurality of blades of cylindrical micro-bubble generators (19) included in the micro-bubble generation unit (18) is configured such that tip ends of the blades are formed so as to face one another around the center of the cylindrical micro-bubble generators (19a, 19b); and by being formed from an elastic member (such as rubber), the tip ends of the blades are configured so as to bend with the base ends as starting points.

An impeller blade formed of a central base portion having a center axis. At least a pair of impeller blades is extended outwardly from the central base portion, with each impeller blade further including an extension. A leading edge is formed on each of the impeller blades, with each leading edge being defined by an outer periphery of the central base portion, and each leading edge having at least a portion that forms a continuous curve with a radius decreasing outwardly toward a radial tip of the corresponding impeller blade, wherein the continuous decreasing radius curve of each leading edge is formed by a portion of an ellipse centered on the center axis, a short axis of the ellipse being equal to a long axis thereof divided by approximately three and one-half. Each blade extension is projected from the corresponding impeller blade opposite of the leading edge.

A blending device is shown and described. The blending device may include a blending container and a power source operatively connected to the blending container. The power source may be configured to supply power to the blending container. The blending container may also include a feature that is powered by the power source.

A method of mixing a rubber composition includes a carbon introduction step and a uniform dispersion step. In the carbon introduction step, on the basis of a deviation between a rate of temperature increase of the rubber mixture (R) and a target value, at least one of a ram pressure (Pr) and a rotational speed (N) of the mixing rotor (2) is PID controlled so that the ultimate temperature of the rubber mixture (R) at the conclusion of the step is within a tolerance range. In the uniform dispersion step, the ram pressure (Pr) or the rotational speed (N) of the mixing rotor (2) is adjusted to reduce a deviation between a value based on successively detected data associated with a predetermined control target and a target value.

A kneader internal inspection device according to the present invention suspends and supports a photographing unit, which is arranged in an interior of a kneader and which photographs the interior, so as to be vertically movable in the interior of the kneader. Therefore, such a kneader internal inspection device is capable of easily inspecting the interior of the kneader.
