A mixing system for mixing fluids or the like in a mixing vessel. The mixing system includes a fixed conduit connected to the top portion of the vessel extends into the vessel. The system also has a rotating shaft having disposed within the fixed conduit that rotates within the fixed conduit while the mixing system is in operation. An impeller is attached to the rotating shaft. The impeller blade has a flat central disk portion, at least a pair of extensions extending from a central disk portion, and at least two leading edges defined by the outer periphery of the disk portion. Each leading edge spans from one extension to an adjacent extension, and each leading edge has at least a portion at which the radius of the leading edge from the center increases to form a continuous increasing radius curve. Each leading edge forms an increasing radius spiral edge surface in between the extensions.

The present invention relates to an aerator apparatus. It comprises an aerator with at least one blade driven around a central axis, and a motor coupled to the at least one blade such that the operation of the motor in a first or a second direction results in the operation of the blade in a corresponding first or second direction. The aerator apparatus further comprises a control device comprising a monitoring mechanism to monitor the current drawn by the motor; and a control mechanism to control the direction of the motor. The monitoring mechanism detects a certain value of the current drawn by the motor and the control mechanism is adapted to direct the motor and coupled at least one blade operating in the first direction to do at least one of (i) stop and/or (ii) operate in the second direction. In preferred embodiments, the monitoring mechanism monitors the current drawn by the motor in relation to one or more of the voltage and frequency applied to the motor. An advantage of certain embodiments of the present invention is that they provide an economical unblocking solution for wastewater aerators where the control device detects a change in the current drawn by the motor, and instructs the motor to direct the aerator into a clean cycle to try to dislodge debris built up during normal flow, when the aerator is running clean.

A method and apparatus is disclosed for maintaining fluid in suspension in a mixing tank including particles includes providing a reversible mixer, rotating the mixer in a normal direction in which particles buildup on the mixer, and, rotating the mixer in an abnormal direction to shed the particles from the mixer.
摘要:
A device for mixing and/or kneading food products. The device includes a container having an inlet, an outlet, and at least one rotary shaft extending substantially in a longitudinal direction of the container. The at least one rotary shaft includes at least one tool, the at least one tool including at least one bar connected to the at least one rotary shaft via spacers. The at least one rotary shaft further includes an operative area to continuously mix and/or knead the food products, the operative area extending in a longitudinal direction of the at least one rotary shaft.

An aeration system for a submerged membrane module has a set of aerators connected to an air blower, valves and a controller adapted to alternately provide a higher rate or air flow and a lower rate of air flow in repeated cycles. In an embodiment, the air blower, valves and controller, simultaneously provide the alternating air flow to two or more sets of aerators such that the total air flow is constant, allowing the blower to be operated at a constant speed. In another embodiment, the repeated cycles are of short duration. Transient flow conditions result in the tank water which helps avoid dead spaces and assists in agitating the membranes.
摘要:
A high-pressure homogenizing apparatus, in which a material receiving recess can be easily cleaned without disassembling/assembling a pressurizing mechanism, is provided. The apparatus includes a high-pressure homogenizing mechanism (1) in which a suspension (2) or semisolid (2′) containing a raw material (G) is passed through the orifice (3) to be subdivided; and a material receiving passage (8) communicated with the high-pressure homogenizing mechanism (1). One of the inserting member (5) and the material processing piston (4) is moved relatively to each, thereby the suspension or semisolid including the raw material is transferred into the material receiving passage (8) so as to be subdivided and processed. When the material processing piston is moved back over open end (6a) of the material processing recess, the cleaning liquid (W) is introduced through the material receiving passage into the material processing recess and the inside of the material processing recess is cleaned.
摘要:
An apparatus for dispensing and mixing fluids from multiple cartridges into a removable container, based on the user input through the provided interface. The user interface allows viewing and adjusting of the mix to be dispensed prior to the actual dispensing. The apparatus is capable of dispensing fluids that have a wide range of viscosities, and that are sticky or that solidify quickly due to the evaporation of the volatile substances they contain.
