Abstract: A kitchen waste wastewater treatment equipment includes a reaction kettle, a discharging mechanism and a pressurizing mechanism. In the process of high-temperature and high-pressure thermal hydrolysis of wastewater in the present disclosure, the pressurizing disk in the pressurizing mechanism continuously moves downwards in a vacuum state in the reaction kettle, reducing the volume in the reaction kettle and thus increasing the pressure. The secondary pressurization of wastewater is achieved while using heating for high-temperature and high-pressure, and the high-temperature and high-pressure environment greatly improves the reaction rate of thermal hydrolysis. The thermal hydrolysis reaction also generates gas for further pressurization, which greatly improves the treatment efficiency of wastewater. Moreover, the pressurizing mechanism and the exhaust annular groove can separate the gas generated after thermal hydrolysis.

Abstract: A mixing device for mixing a powder-liquid mixture, comprises a movable body, arranged within the housing, with a channel formed between the housing and the movable body. An actuator moves the movable body between a closed and an opened position. The movable body comprises a first body section having a first set of openings, and a second body section having a second set of openings. The housing comprises a sleeve with a covering section that covers the second set of openings when the movable body is in the closed position, for minimizing a flow of the mixture through the second set of openings, and be offset from the second set of openings when the movable body is in the open position, for allowing the mixture to flow into the channel through the second set of openings.

Abstract: A beverage carbonating device includes a carbon dioxide production unit and a pressure container. The carbon dioxide production unit produces carbon dioxide gas by mixing at least two reactants. The pressure container stores the produced carbon dioxide gas in a pressurized gaseous state. As a detachable module, the pressure container is sealingly detachable from the carbon dioxide production unit. Accordingly, the carbon dioxide gas is stored and sealed in the pressure container when detached from the carbon dioxide production unit. Further, a beverage vessel is used with the beverage carbonating device.

Abstract: A flow control arrangement for use with a pump in an aquarium includes a main body having an inlet flow conduit and an outlet flow conduit. The main body has a cylindrical wall having first and second opposite open ends and defining an open interior; and a through hole extending through the wall to the open interior. A flow control dial closes the first open end; and an aeration flow dial closes the second open end and is rotatably adjustable relative to the main body. The aeration flow dial has a tubular aeration wall extending into the open interior. The aeration wall has an aperture, wherein the aeration flow dial can be rotatably adjustable to control axial alignment of the aperture with the through hole in the wall of the main body to selectively adjust a size of a resulting orifice from the open interior of the main body to outside of the main body.
