| Carbonaceous components are separated from particulate coal containing inorganic solids by agitating and aerating the coal, agglomerating oil and water to form agglomerates of carbonaceous components of the coal and oil with air trapped in the agglomerates. The air trapped in the agglomerates makes them buoyant so that they collect at the surface of the water, for easy removal, while inorganic residual solids collect at the bottom of the water. The inorganic solids containing coal comprise previously formed agglomerates which are broken down by the agitation to form a slurry. In the latter case the process is for removal of inorganic solids which were not removed during the initial agglomeration. The agitation may be accomplished by a stirrer, impeller or a pump. | ||||||

| PCT No. PCT/DE79/00090 Sec. 371 Date Apr. 21, 1980 Sec. 102(e) Date Apr. 21, 1980 PCT Filed Aug. 18, 1979 PCT Pub. No. WO80/00423 PCT Pub. Date Mar. 20, 1980. A pulp suspension of waste paper which is laden with air bubbles is introduced into a flotation cell. Fine air bubbles rise through the pulp suspension toward the top. Printing ink and other impurities are deposited on the bubbles which form a foam layer on the surface of the pulp suspension. The foam which is laden with impurities is drawn off from the surface. The fibers which have been subjected to preliminary purification in this manner sink downwardly. For reducing the number of cells connected in series to fewer than a third, while obtaining the same degree of whiteness, the fibers which were subjected to preliminary purification are drawn off and are once again supplied to the flotation cell in the form of an air-laden pulp suspension. Alternatively, instead of the air-laden pulp suspension, a water-air suspension can be injected. The air bubbles which are thus introduced once again rise toward the top and traverse the sinking fibers in a counterflow. As a result, an intensive air-pulp contact is created. | ||||||

| A flotation machine consists of a flotation chamber and a rotating gas diffuser. The flotation chamber has a lower mixing chamber and an upper quiescent zone for maximizing float accumulation. The rotating diffuser produces ultra fine bubbles as small as 50 microns in diameter. The size of the bubble diameter can be controlled and produced in any size from less than 50 microns to greater than 10 mm to enable flotation of various materials and/or various sized fractions of materials. The ultra fine bubbles are produced by the diffuser in the same size range as bubbles produced by dissolved air flotation, but without the necessity of pressurizing gas in a first tank followed by depressurizing in a second tank. Since the diffuser is located within the flotation chamber and can vary bubble size, it also provides the advantage of sparged air flotation. This rotating diffuser configuration is a low drag thin disc and, when combined with a specially designed flotation chamber, embodies a flotation machine which produces higher product yields over a wider range of feed size fractions utilizing significantly less energy. | ||||||

| Apparatus for de-inking waste paper pulp using a foam flotation process in which the deinked slurry is to be recycled for the production of paper. The old paper is pulped (slushed), mixed with water and flotation- and other chemicals, to produce a slurry which is introduced into the flotation tank. Movement of the slurry through the flotation tank is achieved by the positioning of one or more water injector nozzles with air inlets which causes a swirling rotation from the injector towards a central outlet. Froth or foam bubbles float to the surface of the slurry carrying ink particles. A baffle plate leads the floated froth or foam and ink particles to a vacuum actuated outlet. | ||||||

| A flotator for use in benefication, coal dressing, wet refining and so forth, incorporating a surface flotation technic. The flotator has a funnel-shaped liquid cell having a bottom of an area smaller than that of the top opening. A bubbling device is constituted by an upper sleeve partly immersed in the liquid contained by the cell, a lower sleeve disposed coaxially with the upper sleeve and fully immersed in the liquid. The upper end of the lower sleeve is spaced by a predetermined distance from the lower end of the upper sleeve to form therebetween a spaced region located at a small depth from the liquid surface. The bubbling device further has a rotary blade unit constituted by upper and lower blades separated by a flat partition plate. The rotary blade unit is adapted to rotate around the common axis of the upper and lower sleeves, and has a thickness or axial height substantially equal to the aforementioned predetermined distance in the spaced region, and is located such that the flat partition plate is located at the heightwise mid point of the spaced region. The flotator further has a liquid surface stabilizer constituted by a frusto-conical member disposed around the bubbling device and adapted to deflect the liquid downwardly. Further, provided are a feeding passage having a feed gate opening in the bottom area of the cell and a discharging passage having a discharge gate spaced from both of the feed gate and the lower edge of the liquid surface stabilizer so as to avoid the "short-circuiting" of the liquid. | ||||||

| PURPOSE: To enhance flotation capacity by using both-face blade rotary body to cause effective foaming and liquid surface stabilizer to stabilize liquid surface. CONSTITUTION: A rotary body 3 having blades 3b at lower and upper sides of partition plate 3c is concemtrically mounted in the upper and lower cylinders 2a, 2b. Multiple dispersers 5 are mounted on the periphery facing the rotary member 3. The outer periphery is installed with a liquid stabilizer 7. Air and liquid are mixed by rotation of the rotary body 3, are subjected to centrifugal force and divided into fine particles by the dispersers 5, are downwardly deflected by thr stabilizer 7, and jetted out without disturbing liquid surface. Liquid sucked from the lower cylinder 2b contains only a little bubbles, so that useless power due to bubbles is not used. Because liquid is supplied from the supply route 9, the liquid is not flowed from outlet route 10 without passing bubble section 6. COPYRIGHT: (C)1980,JPO&Japio | ||||||
