    A method of and an apparatus for separating a liquid medium in different components by gravity in a manner that a medium to be separated is set in slow rotating motion (2) with the axis of rotation substantially vertical, so that the heavier component concentrates in the bottom section of a slow-moving vortex and the lighter component concentrates in the top section of a slow-moving vortex (2). For a more pronounced separation activity and simpler equipment, two or more slow-moving vortexes (2) are contacted with each other in horizontal direction. The outer sections of various settling basins (1) are in contact with each other by way of a gate or channel (40). Various sub-basins (1) can be connected in series or in parallel.

    (54) METHOD FOR SEPARATION OF COMPONENTS FROM LIQUID ENVIRONMENT WITH THE HELP OF FORCE
    (57) The invention relates to a method for the separation of components from a liquid medium by means of gravity and makes it possible to increase
    efficiency. The separable medium is tangentially supplied to the first whirlpool of a series of chambers having a vertical axis of rotation, the heavier component is concentrated in the bottom part and removed to its center, and the lighter component is concentrated in the upper part of the chamber. Two or more whirlpools are brought into contact with each other in a horizontal direction, while whirlpools interact at least part of the height of the chamber, and part of the whirlpool flow is directed from the periphery of the whirlpool to the periphery of the next whirlpool. Whirlpools parallel to the stream interact with a friend. Whirlpools, arranged in series with respect to flow, interact with each other. The lighter component is released from the last chamber through its outer edge, and the heavier component is released into a common container located behind the chambers 3 of a 3 f f-ly, 7 sludge

    part 4, and the lighter component is concentrated at the top of the chamber. Some part of the outer edge of the slowly moving whirlpool 3 of the preceding tank passes into the outer portion of the subsequent sedimentation tank, where said slow moving whirlpool 3 has a continuation. A row (Fig. 1 v 2) contains five successive sedimentation tanks. When the flow slowly passes from the first reservoir to the last one in the row, gravity concentrates the heavy component in the lower portions of the reservoir, and the light component in the upper portions. In this case, the light component is discharged only from the last reservoir at the surface along the outlet 5. The light component is discharged over the overflow bridge 6. In the preceding tanks of this pitch, the Heavy component s is discharged from bottom 4 of the outlet 7, regulated by by the size of the orifice, a valve, or a backpressure so that an excessive component of the light component does not get caught by the heavy component. In this case, the first four units of the row are pre-separators with a not very significant discharge stream, but the amount of the heavy component decreases and precipitates towards the bottom. The sedimentation tanks are round, but aggregates with tanks of other shapes, such as elliptical, polygonal, and various arcuate shapes, can be used. The collection of heavy and light components can be made from the geometric center of the tank or from The heavier component is discharged into a common container 8. If the level of the heavier component in container 9 rises, the amount of overflow increases. Thus, the level of the overflow bridge b and the level in the total relative flow container 8 remain almost unchanged due to a kind of self-regulation. If you raise the flow level of the more heavy component higher, the flow rate of the heavy component increases relative to the flow rate of the light component. The whirlpools collide at rounded edges 9. If sharp edges are used in which a collision occurs, it is possible to create an oscillatory motion in the sedimentation tanks when the flow periodically passes through different
    sides of the hem. This reciprocating, oscillatory motion is preferable to keep the collected sediment at the bottom and to bring it gradually to the site.
    collection.
    The bottom parts of the tanks 1 (FIG. 3) are staggered in the vertical direction. The steps of such an arrangement prevent the direct flow near the bottom from the front end of the row of aggregates towards its rear end. The bottom layer containing the heavy component tends to remain below the steps. Since the liquid layer is preserved near the tail end, separation of the heavy component is easier as the deposition distance becomes shorter. Step arrangement can be used
    0 to increase the height of the tangential inlet 2 in order to reduce the inlet speed. It is possible to cut off part of the entrance 10 by means of a blocking plate 11.
    5 A plate for blocking the flow can also be installed to prevent the passage of floating objects and particles to said exit 5 for the light component (L-shaped), which
    0 prevents the formation of turbulence. An effect similar to that obtained by stepping can be achieved by positioning near the bottom of some vertical plates 11 to block flow, the height of which is appropriately selected. The lightweight component can be discharged at various stages in a series of sedimentation tanks 1 by using overflows b through an outer board. They can be formed in the middle part of the row (fig. 3) or at the end of the row. Through the gradual unloading of a lightweight component can be created,
    If possible, small vertical flows, while the upward flows do not pick up a heavy component from the bottom and do not carry it forward.
    Parallel and series tanks 1 (Fig. 4) are in contact with each other by means of inputs 10. Sludge tanks create a system with only minor flow dividers 12 between different tanks. Such de ligas l and 12 fluxes can be made in the form of light construction or hollow, in the form of separate units on the common bottom or floor of the tanks 1. In the case shown in figure 4, an effective oscillatory action can be provided if the dividers
    11 threads are installed with sharp edges, which have a collision. In FIG. 4, the outlet for the light component is shown similarly to the outlet in FIG. 2, but for all units with a tank.
    Fig. 5 shows a diagram in which the size of the precipitating tanks 1 varies. At the beginning of the row, a smaller diameter creates a stronger lower current than that which occurs in large tanks towards the end. The size of the precipitating tanks in the row can also be gradually reduced.
    Figure 6 shows a series of precipitating tanks 1 arranged in a zigzag manner. The stream passing through the device from inlet 2 to outlet 5 is forcibly moved to the greatest possible distance, which means that there is a long time for precipitation. In large reservoirs 1, the main flow turns more than 180 °, which leads to an intensification of the cup phenomenon in the turning zone.
    Fig. 7 shows a device in which the inlet 10 is provided with a diverting rib 13 for strengthening the tangential flow direction. Tangential inlet 2 is located outside the radius of the first unit with tank 1. Accordingly, due to the outer wall, the inlet stream is forced to work closer to the center of the first tank 1. This type of device, in particular, is preferable in the lower part of inlet 2 near the bottom.
