In a rapid stirrer that stirs sludge and a flocculant in a tank with a stirring blade, the rotation speed of the stirring blade is increased at a set rate with an increase in the amount of charged sludge, the rotation speed of the stirring blade is reduced at the set rate with a decrease in the amount of charged sludge, and flocculated flocs having a fixed floc diameter are stably generated even when operating conditions change so as to fluctuate the amount of charged sludge.

An apparatus for accommodation and dispensing of miscible materials has an accommodation vessel having a lower region in the form of a truncated cone, with a lower discharge opening in the direction of gravity, and ha a mixing mechanism shaft disposed centrally in a mixing space, which shaft has at least one mixing mechanism that revolves in the accommodation vessel. The discharge opening is provided with a displacer apparatus that projects into the interior of the lower region of the accommodation vessel. The lower end of the mixing screw or mixing spiral of the mixing mechanism projects into the approximately V-shaped channel between the lower vessel wall and the displacer apparatus.

Provided is a bidirectional simultaneous rotary blade bundle for a mixer, the bidirectional simultaneous rotary blade bundle including: a housing; a forward rotary shaft installed on the housing; a forward rotation blade provided on the forward rotary shaft; a central gear axially installed on the forward rotary shaft; horizontal insertion gears engaged with the central gear; a reverse rotor, of which inner gear teeth are engaged with and rotate on the outside of the horizontal insertion gears; and a reverse rotation blade installed on the reverse rotor, wherein the horizontal insertion gears are rotated in the reverse direction according to the forward rotation of the central gear such that the inner gear teeth are rotated in the reverse direction.

The problem of providing a stirrer capable of more effectively shearing a fluid to be treated is addressed, by using the action of an intermittent jet stream. A stirrer is provided with a rotor having a blade and a screen, which are relatively rotated such that the fluid to be treated is discharged from the inside of the screen to the outside as an intermittent jet stream through a slit in the screen, the stirrer satisfying condition 1 and condition 2. (Condition 1) the relationship among the width b in the rotating direction of a tip part of the blade, the width s in the circumferential direction of the slit, and the width t in the circumferential direction of the screen member is b2s+t. (Condition 2) the relationship between the width b in the rotating direction of the tip part of the blade and the maximum inner diameter c of the screen is b0.1c.

Provided is a stirring device including: a stirred tank, of which an inner peripheral wall has a circular shape in cross section; and at least one flow impeller and at least one shearing impeller that are located inside the stirred tank and configured to be rotatable independently of each other, in which rotational centers of the flow impeller and the shearing impeller are coaxially provided, the flow impeller rotates around a vertical axis along the inner peripheral wall of the stirred tank to form at least a flow directed toward a lower side in the stirring object existing in the stirred tank, and the shearing impeller imparts a shearing force to the stirring object and is provided on a radially inward side of the flow impeller in the stirred tank and at a position contacting the flow of the stirring object formed by the flow impeller.

A filling apparatus comprises a filling material reservoir and a filling chamber that is connected to the filling material reservoir with a filling opening configured to dispense filling material into cavities in the rotary press. A first rotatably driven stirrer blade wheel with one or more stirrer blades and a second rotatably driven stirrer blade wheel with one or more stirrer blades are arranged in the filling chamber. The first rotatably driven stirrer blade wheel has at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the second rotatably driven stirrer blade wheel.

A rapid stirring machine including a tank for stirring sludge and a flocculant; a drive shaft disposed in the tank; and an edged turbine blade attached to the drive shaft, the edged turbine blade including turbine blades that are disposed along a virtual circle centered around the axis of the drive shaft, on at least one of the front and back sides of the edged turbine blade in the axial direction of the drive shaft, the turbine blades being raised in the axial direction of the drive shaft.

Disclosed is a dissolution mixer, which includes: a dissolution bath configured to accommodate a powder and a solvent for dissolving the powder; a powder input unit located at an outer side of the dissolution bath; an impeller installed to be rotatable inside the dissolution bath; and an anchor located inside the dissolution bath and having a passage of the powder inputted by the powder input unit and a powder spouting hole connected to the passage.
