41 Tangential solid separation device JP2000594576 1999-08-25 JP4514958B2 2010-07-28 トラバウニズ ゲオルゲ; ニームツェジック ベルンハルト; メンケ ルカス; ヘインッ ロベルト
The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A rotationally symmetrical flocculation/flow reactor is provided with outlets in the lower part thereof and is arranged in a separating tank. At least one suspension inlet extends eccentrically into said reactor. The supplied suspension is guided into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor via the suspension inlet. A circular flow is thus created which drains off from the flocculation reactor downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank. In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards. One advantage of the invention is that said flow of the mixture has to travel a longer way to the outlets in the area of the wall of the tank due to the tangential flow component. The solid matter can be separated more effectively by virtue of the longer travel path or the longer presence in the separating tank.

The de-inking procedure consists of circulating the pulp in a flotation cell comprising a chamber (2) with a vertical axis in which the pulp can move downwards from top to bottom, passing through a series of stages (E1...En), in each of which bubbles (13) introduced in the lower part of the chamber pass through it. The bubbles reach the top of the chamber in the form of a foam (5) carrying particles of non-soluble materials, the foam being removed at the top while the de-inked pulp is drawn off at the bottom. In each of the aforementioned stages the rising bubbles follow the under-surface of a spiral guide (12) to reach the passages taking them to the higher levels. In addition, the speed of the pulp is accelerated at the passage entrances by a progressive reduction in the passages' cross-section to draw the bubbles through and mix them with the pulp.

<P>PROBLEM TO BE SOLVED: To provide a process for de-inking paper pulp and flotation cell reducing energy consumption, controlling waste and enabling a larger modular property than the conventional flotation cell. <P>SOLUTION: The process comprises introduction of pulp from a main inlet (3) of the flotation cell having a vertical outlet conduit (16) in the vessel (2), de-inking of the introduced pulp in a transfer process of the introduced pulp from top to bottom by bubbles introduced from the bottom of the vessel, wherein bubbles can rise along a guiding means (12) to reach a bubble passage (13) for passing to upper level in each step (E1-En), and in the section of the bubble passage (13) acceleration of the pulp speed is induced and that causes suction of the bubbles coming out, promotes mixing of the pulp with bubbles, the acceleration of the pulp speed is obtained by step down of the passing cross-sectional area of the pulp on the guiding means (12) on the adjacent upper stream of the bubble path. <P>COPYRIGHT: (C)2005,JPO&NCIPI
45 Apparatus and method for supplying the coolant in the cutting machine and grinding machine JP52918697 1997-02-12 JP3354156B2 2002-12-09 義和 中井
A method and apparatus for feeding coolant liquid to a lathe with a nozzle (53) having a discharge port (58) of substantially rectangular cross section and a constricted curved surface portion (62) on its inner wall to produce a turbulent flow and a loosely mounted tongue piece (59) crossing the section of the discharge port and projecting outside the port. The coolant is thus discharged as a collection of particulate turbulent flows containing air bubbles drawn into the coolant liquid as it passes by the tongue piece. The coolant is caused to impinge on the rotating peripheral surface (56) which is continuous with the region of the workpiece in contact with the cutter (57). <IMAGE>

In a centrifugal rotor (1) for separation of a substance from a liquid mixture supplied to the centrifugal rotor there is delimited a separation chamber (7) having peripheral outlets (30). The centrifugal rotor includes an outlet device (20-28) for intermittent opening and closing of the outlets (30) during rotation of the centrifugal rotor. An actuation device (31-40) may cause the outlet device (20-28) to keep the outlets (30) open to a varying extent and/or during a varying time, and a control device (43) is adapted to control the actuation device (31-40) in response to a sensed value of the amount of mixture supplied to the rotor, such that a predetermined amount of separated substance (29) having collected in the separation chamber (7) is discharged through the outlets (30) each time these are opened and closed.
47 Method and apparatus for separating the heavy fraction of the aqueous slurry from the light fraction by centrifugal action JP53851197 1997-04-17 JP2000508968A 2000-07-18 アイヒラー,ディートリッヒ
The invention relates to a process and apparatus for the separation of heavier from lighter fractions in aqueous slurries by means of centrifugal force. The slurry is made to spin in the separation chamber under the influence of the differential pressure generated between the inlet and outlet of a cyclone separation chamber (4). The differential pressure, which can amount to several bar, is generated by means of a pressure increasing stage in the form of a transport rotor device (20) which acts in conjunction with a stator arrangement (22); essentially this takes place immediately in front of the inlet of the slurry into the separation chamber (4). The rotor blades of the cyclone rotor device (10) as the rotor blades of the transport rotor device (20) can be mounted on the same rotary shaft (5) in order to induce additional rotary force into the slurry. The separation of floatable fractions in aqueous slurries is effected by the presence of micro gas bubbles introduced into the separation chamber (4). The separated floatable fractions can be removed from the gas bubbles to which they adhere by means of an anti-foaming device driven by the rotary shaft (5) of the transport rotor device (20).

The apparatus includes a powered bowl assembly having a tubular shaft journalled within a base of the apparatus. A pressurized air flow is discharged into slurry in the bowl assembly via a circular array of bubble generators. An impellor discharges the slurry outwardly against an upwardly inclined annular surface of the bowl assembly to cause the slurry to merge upwardly with the streams to promote flotation. Slurry within the bowl assembly forms a vortex with particle flotation forming a froth layer inwardly of a slurry vortex. The froth exits the bowl assembly upwardly past a barrier partially closing the bowl assembly. Heavier gangue particles exit via an outlet about the bowl assembly periphery. A collector shroud is partitioned to receive the froth and the heavier waste material. A modified form of the apparatus includes an independently powered bowl assembly and impellor.

An apparatus and method for de-inking waste paper pulp using a foam flotation process to recycle printed waste paper for the manufacture of new paper. Pulped printed paper is fed as a slurry to an inlet of a shallow tank. Internal guide walls in the tank establish a flow path from the inlet to an outlet. The walls are sized and positioned to create a generally uniform cross-sectional flow area. A plurality of modules are disposed along the flow path. Each module includes at least one injector that aerates the flow and an extractor that removes floated ink foam. A portion of the flow from each module is recycled to an upstream module, preferably by a conduit and associated pump. In a preferred form, an injector (or injectors) alone located at the inlet is fed by the next downstream module and an extractor alone is located near the outlet. The invention also includes a main recycling loop from the downstream end of the flow path to the upstream end. This main recycling loop has a large flow rate compared to the recycled flow between the modules.

In deinking, the flotation of fiber suspensions is performed in a cylindrical tank 2 to which the fiber suspension is fed through a coupling means 36 as primary stream. The fiber suspension is already aerated and is withdrawn through a suction connection 33 below the coupling means 36 and fed after another aeration through a secondary connection 35 above the coupling means. The volume of the circulated secondary stream is greater than the volume of the primary stream. It is thereby assured that the fiber suspension is aerated at least twice and thus better cleaned.
