The stirring part is disposed in the accommodating cavity and configured to mix the materials in the accommodating cavity. The dispersing part is disposed in the accommodating cavity and includes a first cylinder and a second cylinder. The first cylinder has a first cavity in communication with the accommodating cavity, the second cylinder is located in the first cavity, and the second cylinder has a second cavity in communication with the accommodating cavity. The driving part is connected to the stirring part and the dispersing part. The materials mixed in the accommodating cavity flow into the second cavity and flow out after being dispersed in the dispersing part.

This invention belongs to the field of biomass energy utilization at the large scale. A material stirring device for a biomass bin includes a transmission mechanism, a main stirring mechanism, and an auxiliary stirring mechanism. The main stirring mechanism includes a cylinder connected to the transmission mechanism. The outer wall of the cylinder is provided with a hollow stirring rod. The auxiliary stirring mechanism includes a rotating shaft vertically penetrating through the hollow stirring rod. Both ends of the rotating shaft are provided with stirring blades and the rotating shaft is connected to the transmission mechanism. That the stirring device is easily damaged due to too high density of the biomass material is overcome through the automatic conversion adjustment of the main and auxiliary stirring mechanisms. The continuous discharge efficiency of the biomass bin is improved by the organic integration of over and partial stirring.

A fine-bubble mixed liquid producing apparatus 1 includes a reservoir 4 and a bubble feeding means 6 for feeding bubbles to a liquid L stored in the reservoir 4, wherein the bubble feeding means 6 includes a rotary cylinder 20 having an emitting part 22 on the outer circumferential surface, the emitting part 22 for being rotationally driven by a drive means 10, a circulating means 40 for drawing out the liquid L stored in the reservoir 4 and feeding the liquid L from the emitting part 22 to the reservoir 4, and a gas-liquid mixing part 50 for mixing bubbles with the liquid L circulated by the circulating means 40. This apparatus enables a fine-bubble mixed liquid to be efficiently produced.

A crystallization device (4) includes a stirring blade (W) including a plurality of radially penetrating holes (h) and rotating about a rotating shaft (3), a reaction tank (1) having a bottomed cylindrical shape and concentrically accommodating the stirring blade (W) inside, a first liquid supply portion (5a) provided on the reaction tank (1) and supplying a first reaction liquid (L1) to the inside of the reaction tank (1), and a second liquid supply portion (5b) provided on the stirring blade (W) and supplying a second reaction liquid (L2).

Inside a driven cylindrical housing 23 that is a cylindrical rotation member 13, a liquid to be mixed 4 is caused to become an inner circulation current f by extruded plate portions 24A-24D. Discharge ports 22A-22D formed in the cylindrical housing 21 discharge a portion of the inner circulation current f outward as outer discharge current d1-d4 by centrifugal force. At the same time, the outer portion of the liquid to be mixed 4 is sucked into suction ports 23, 30 as suction current e1-e3, h1-h4, thus mixing the liquid to be mixed 4 in the mixing tank 3.

A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flask 2 and a lower flask 3 includes a body that defines an opening in which a sand mold is to be molded. The body has at least one inlet 101 for introducing the mold sand into the opening. Two flanges 102 are extended from the body such that they are opposed to each other across the opening. Each flange has a through bore. The flask also includes engaging members for engaging an actuator in the outside of the flask such that a force or forces from said actuator could be transmitted to the flask. An upper flask 104 and a lower flask 105 are opposed to each other across a pattern plate 107. They are integrally assembled to make a flask unit by means of a pair of connecting rods 106 that are fitted in each bore.
