Abstract

The invention relates to a flotation cell line, wherein there are installed, in order to treat the flotatable material, several flotation cells so that the flotatable material can be set to flow through the flotation cell line. According to the invention, the flotation cells (1, 2, 3, 4, 5;31, 32, 33, 34, 35) that are arranged successively in the flowing direction (22, 52) of the flotatable material, are at least partly installed in parallel with respect to each other.

Description

CEL-AFFDE FLOTATION LINE DESCRIPTION OF THE INVENTION The present invention relates to a line formed by cells used in the treatment of floating materials, cell lines which is installed with respect to each other, so that at least one cell can be removed from the process without essentially deteriorating the operation of the flotation cell line. In a flotation cell, materials similar to suspension are treated in order to remove the desired ingredients that can be used from the rest of the material. The main task of the flotation cell is to keep the flotable material in suspension, to feed air in suspension and to disperse the suspension in small air bubbles as well as to transport the usable ingredients, that is, the concentrate, and the rest of the material to separate positions . However, with respect to the recovered concentrate, the efficiency of the flotation cell is essentially low. Accordingly, in order to obtain the desired degree of concentration for the usable ingredient, the flotation cells are usually coupled in series, so that the waste of the preceding flotation cell serves as a feed for the successive flotation cell. The concentrates that are obtained from the cells of the flotation cell line generated accordingly are then combined and transported for further treatment. In a conventional flotation cell line, the cells are coupled in series - one with respect to the other, so that the entire flotation cell line must be stopped and production is interrupted even in the case where only a cell in the flotation cell line needs repair or maintenance. Because the capacity of the flotation cells as such has increased, and due respectively to the fact that the number of parallel photon cells has decreased, the shared relative capacity of each float cell line becomes large. When this type of flotation cell line must be stopped, in order to maintain or repair a cell in the line, the procedure remarkably cuts the degree of utilization of the flotation process, and therefore causes high additional costs for the process. The object of the present invention is to eliminate some of the drawbacks of the prior art and obtain an improved flotation cell line, wherein the removal of a flotation cell from the line does not cause any essential change in the operation of the line of Flotation cell, and therefore it is possible to reduce the space needed for the flotation cell line. The essential novel features of the invention are apparent from the appended claims.
According to the invention, the flotation cell line is formed of flotation cells, which are provided with inlet and outlet opening for the flotable material, so that the flotable material can be transported from a flotation cell to at least two flotation cells that are located in succession to the flotation cell, when observed in the direction of flow of the flotable material. Therefore, the floatable material can alternatively be transported either to the cell in the flotation cell line that is located posteriorly in the flowable material flow direction, or by passing the cell which is located proximal in the direction of flow, to at least one subsequent cell in succession in the flow direction of the floatable material. In the case where the cell in question is the cell which is located at the end in the flow direction of the buoyant material, the buoyant material can only be directed to the last cell or further treatment after the flotation cell line. In addition, when the buoyant material is fed to the flotation cell line, the material can be fed either to the cell which is located first in the flow direction of the buoyant material, or by passing the first cell to the cell that it is located second in the flow direction of the floatable material. When the floatable material, according to the invention, is directed passing that cell in the cell line of irl &? i? t? & x .asfafe flotation which is located next to the flow direction of the floatable material, the flotable material in the waterline can be further directed, regardless of whether the flotation cell is removed for use , so that the flotation cell line can be used in the treatment of the flotable material. In addition, in a flotation cell line according to the invention, the flotation cells are installed at least partially parallel so that the space can advantageously be saved in the direction of flow of the waterline. flotation cell, and simultaneously the interval between two flotation cells is reduced, when the flotable material is directed past the cell in need of repair or maintenance. In the flotation cell line according to the invention, the cells are interconnected by means of conduits, A flow control member is installed at the cell exit opening, or between the cells, which guides the buoyant material to the feed inlet of the cell which is located close to the flow direction of the cell. the float cell line, or alternatively to the power input of the the cell that is located closest to the next cell. Advantageously, the number of inlet and outlet openings of the cells that are provided in the flotation cell is one or two. However, a larger number may also be applied, if desired. In the flotation cell line according to the invention, the number of inlet openings can be altered and output of the individual float cells, in which case different types of float cell can be combined in a float cell line. According to the invention, when the two inlet openings and the two outlet openings are used in the cells of the flotation cell line, the passage of the floating material either to the next cell or to the conduit passing the next cell is it controls in advance in the flotation cell itself, by maintaining an outlet opening and an inlet opening that is provided in the flotation cell is received open by means of the flow control members, so that the buoyant material flows from one cell to another. The passage of the floatable material from a flotation cell to the cell located later in the float cell line, or passing the next cell, can also be placed so that the floatable material is discharged through the same outlet regardless of the whether the floatable material passes to the next flotation cell or to the conduit that passes to the next cell. Now the flow control member of the floating material is installed outside the flotation cell, in the conduit that connects the cells. When only one output is used in the float cell, it is possible that one or two inputs are used in the next receiving float cell, because the floating material conduit means the passage of a float cell that can be connected to the float cell. that piece of conduit which provides the buoyant material to a direct contact between two successive float cells, or in conduit can be connected directly to the float cell as a separate inlet opening. In the flotation cell line according to the invention, the cells which are located successively in the flow direction of the buoyant material are installed at least partially in parallel with respect to each other. Therefore, the distance of the first and the last cell in the flotation cell line is reduced, when observed in the flow direction of the flotable material, and the flotation cell line as such requires less space than a line of conventional flotation cell. Also now the distance between the cell and the cell that is located later in succession, when observed in the direction of flow of the floatable material, it is essentially reduced. Similarly, the conduit placed between a cell and the cell located next in succession, when observed in the direction of flow, also essentially short and easily installed in its place. The distance read by the buoyant material in the flotation cell line remains essentially the same as in a conventional flotation cell line, in case the buoyant material passes through all the cells in the flotation cell line, but the distance is essentially shortened, in case the ^^? ¡¡¡¡^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ The invention is explained in more detail with respect to the accompanying drawings, in which Figure 1 is a schematic top view illustration of a preferred embodiment of the invention, and Figure 2 is a schematic top view illustration of another preferred embodiment. of the invention. According to Figure 1, cells 1, 2, 3, 4 and 5 of the flotation cell line which are sequentially located in the flow direction 22 of the buoyant material are installed partially in parallel with respect to each other , so that between the flotation cells 1 and 3, a conduit 6 is installed, through which the floating material can be transported, when necessary, passing the flotation cell 2. Respectively, a conduit 7 is installed between the flotation cells 2 and 4 in order to transport the floating material, when necessary, passing the flotation cell 3. Furthermore, a conduit 8 is illustrated which is installed between the flotation cells 3 and 5 in order to transport the Flotable material passing the flotation cell 4. In the flotation cell line according to Figure 1, the floatable material is fed by means of a feeding device 9. The supply device 9 is connected to both cell 1 and cell 2 via conduits 10 and 11. In the case where cell 1 is removed and there is no use, the floatable material is fed directly to cell 2 via conduit 11. Normally, the feed of the floatable material within flotation cell 1 is transported in the flotation cell line by means of an inlet 12 to the cell 2 of flotation. In the case in which it is necessary to go through the flotation cell 2, the floating material is transported, via an inlet 13, to the conduit 6 and in addition to the flotation cell 3.
