Definitions
- the present invention relates to a centrifuge with egg nem stationary outer housing, a rotatably mounted in the outer housing centrifugal drum with an outer wall, a drive for the centrifugal drum to rotate dersel ben, a cleaning device for the deposited on the outer wall of the centrifugal drum sediment and inlets and outlets , Wherein the centrifugal drum has chambers separated from each other by annular horizontal partitions.
- centrifuge is known for example from DE 199 25 082 B4.
- the well-known centrifuge is classified as a wet classification device with a arranged in the outer housing and overhung centrifugal drum with an inner wall, extending from below into the recess formed by the inner wall bearing housing and a vertically disposed, extending from below through the bearing housing shaft for rotating the Centrifugal drum formed.
- Such a centrifuge is used, for example, as a wet classification device for the separation of the coarse fraction of powders use.
- ultrafine materials with a particle size between 0.1-5 gm are being used.
- the solid is mixed with a liquid in a premix tank to obtain a suspension.
- the suspension is introduced into the wet classifier designed as a centrifuge. Within the rotating centrifugal drum who the heavier and coarser particles faster than the lighter and finer the suspension out radially against the drum wall, where they settle as sediment.
- the sediment is sier adopted in cleaning phases of the Nassklas released from the drum wall, for this purpose, depending on the embodiment, cleaning fluids, mechanical cleaning equipment, such as knives, etc., are used.
- the sediment redispersed in the cleaning liquid is removed from the centrifuging drum and fed, for example, to a separately arranged ball mill, in which the coarse fraction of the redispersed suspension is ground.
- the treated suspension can then be reintroduced into the system.
- the classified suspension is continuously withdrawn from the wet classifier during the classification process and fed to further use.
- the present invention is therefore the task yakrun de to provide a centrifuge of the type described above, which has particularly good flow conditions within the centrifugal drum.
- the inventively provided through holes in the individual chambers separating partitions provide a pressure equalization between the chamber and chamber and allow a flow through the suspension to be classified from chamber to chamber. They therefore have the func tion of calming holes, so that within the centrifugal drum between the individual chambers largely uniform and calm flow conditions prevail, since a balancing effect on the intended through holes is achieved.
- the balancing effect achieved ensures a largely uniform functioning of the centrifuge over the height of the spinning chamber, so that a uniform centrifuging or classifying effect is achieved.
- the intended through holes are formed as slots or as tail holes.
- Long holes are characterized by a straight axis, while tail holes have a curved axis.
- the invention provides in this case a special position and orientation of the slots / tail holes, wherein in one embodiment, the axis of the slots in the direction of rotation of the centrifugal drum from radially inward obliquely ra dial extends radially outside.
- the tail holes are preferably curved in the direction of rotation of the centrifugal drum from radially inward kon vex radially outward.
- the through holes By forming the through holes as slots or tail holes a forced flow is given, so that in this way the flow compensation between the chamber and chamber is realized via directed flow effects. Due to the special positioning of the elongated holes / tail holes, a forced flow in the direction of rotation of the centrifugal drum is realized obliquely outward in the direction of the outer wall of the drum, so that improved cleaning effects can also be achieved as a result.
- the curved tail holes ensure smoother flow conditions. As they form an arch in the outer wall of the
- the apertures are preferably formed as narrow slots which extend along the outer wall over parts of the circumference of the respective partition wall.
- Yet another development of the invention relates to the feature that the outer wall of the centrifugal drum has radially inwardly projecting annular projections, with which the partitions are connected.
- This embodiment has the advantage that for attaching the partitions no welding process must take place directly on the outer wall of the centrifugal drum, so that therefore no damage to the outer wall are possible by the welding process. Rather, the welding process can take place at the intended annular Ansurgi zen, ie at a distance from the outer wall of the centrifugal drum.
- the centrifugal drum is therefore made directly with appropriate approaches to a direct Welding of partitions to avoid.
- the connection with the lugs can be done for example by welding, gluing, shrinking or other connection methods.
- the centrifuge according to the invention is designed in particular as a wet classifier.
- a wet classifying device is described, for example, in the initially-mentioned DE 199 25 082 B4.
- the centrifugal drum is preferably mounted on the fly inside the statio nary outer housing.
- a bearing housing extending from below into a recess formed by an inner wall of the centrifugal drum and a vertically arranged, from the bottom by the bearing housing extending shaft for rotating the centrifugal drum can be provided.
- the slenderness ratio of the centrifugal drum L / D is preferably 0,8 0.8, where L is the length or height of the classification surface available in the centrifugal drum, and D is the inner diameter of the centrifugal drum.
- the centrifuge has as a cleaning device a combination of mechanical features and a device for supplying a dispersing liquid. With such a cleaning device succeeds to skim or remove the sediment cake without the risk of damage to the
- Cutting devices and these carrying waves of the cleaning device occur.
- the wear on the cutting devices is thereby reduced.
- the cleaning device comprises a shaft which can be pivoted or linearly moved in the centrifugal drum and has at least two strip-shaped parts on its circumference
- Cutting devices are arranged, which have a gap between them at their adjacent ends, and means for introducing a dispersing liquid into the centrifugal drum.
- An example of such a cleaning device is described in EP 1 434 655 B1.
- Figure 1 shows a longitudinal section through a sizing device designed as Nassklas centrifuge, where in the provided on the shaft of the cleaning device cutting devices are not shown;
- Figure 2 is a horizontal section through the spin drum of the centrifuge of Figure 1 with a view of an annular partition wall;
- FIG. 3 shows a partial vertical section through the lock the drum with a part of the cleaning device
- Figure 4 is a section along line A-B in Figure 3;
- Figure 5 is an enlarged view of a slot of a partition wall
- Figure 6 is a sectional view of the attachment of a partition wall on the outer wall of the centrifugal drum.
- the centrifuge in the form of a wet classifying device shown in FIG. 1 has a stationary housing 1 with a lid 15 arranged thereon.
- the stationary housing 1 is mounted on a storage rack via suitable vibration damping devices.
- a centrifugal drum 2 is arranged with a vertical axis, which is offset by a vertical shaft 8 in rotation.
- the vertical shaft 8 extends from below into the centrifugal drum 2. It is surrounded by a bearing housing 11 which contains an upper main bearing 9 and a lower second bearing 10 for supporting the shaft 8.
- the bearing housing 11 is fixed to a plate 17, which in turn is fixed to the stationary housing 1.
- the shaft 8 extends through the bearing housing 11 and the plate 17 downwards via a suitable Kupplungseinrich device 18 to a direct drive forming electric motor 12.
- the speed of the shaft 8 is adjustable.
- the centrifugal drum 2 has a suitable supply (not shown) for the suspension to be classified, which extends, for example in the form of a tube through the open top centrifugal drum in this up to its lower end region and there has an outlet opening.
- the classified suspension is withdrawn, for example via a drain pipe 16 from the upper end of the centrifugal drum 2.
- An exhaust pipe 14 at the lower end of the centrifugal drum is used to remove the sediment.
- the centrifugal drum is thus annular in its lower region and circular in its upper region.
- Horizonta le partitions 4 divide the interior of the centrifugal drum in six superimposed classifying chambers 3, in the radial end regions of the sediment is deposited. This is removed from there via a cleaning device shown schematically at 13.
- the individual separation chambers forming partitions 4 are provided with individual through-holes 31, which are distributed to each other at the circumferential distance of the partition walls 4 To order.
- these through-holes 31 are not shown, whereas they are shown in FIG. Figure 2 is a horizontal section through the centrifugal drum 2 with a view of one of the ring-shaped
- Partitions 4 extending inwardly from the outer wall 30 of the centrifugal drum.
- the through holes 31 are formed as elongated holes whose longitudinal axis is in the direction of rotation of the centrifugal drum 2 extends radially inward obliquely radially outward. The direction of rotation of the centrifugal drum 2 is therefore in Figure 2 counterclockwise.
- a through hole 31 is shown in De tail in Figure 5 on an enlarged scale.
- circumferentially extending openings 32 are provided on the outer edge of the partition wall 4 with circumferential spacing
- the through-holes 31 allow a flow through the separation chamber 3 to the separation chamber 3 and provide a forced flow in the direction of the longitudinal extent of the slots. As a result, more functional flow conditions (avoidance of turbulence, etc.) and better cleaning effects are achieved. In particular, particularly gentle flow conditions are achieved.
- the openings 32 provided on the outer edge of the dividing wall ensure a targeted axial flow at the outer edge of the individual separating chambers and thus prevent the formation of projections in the respective chamber corners, so that better cleaning effects are also achieved as a result.
- Figures 3 and 4 show the more detailed design of the cleaning device in conjunction with the partitions 4 and separation chambers 3.
- the cleaning device has a Wel le 20, on which cutting devices 21, 22 are arranged, which are set so that they at an angle ( a / 2) of 15 ° -45 ° to a shaft axis perpendicular intersecting plane are arranged.
- the main plane of the Schneidvorrich lines 21, 22 extends in the illustrated here Embodiment perpendicular to the axis of the shaft 20, depending but also can run obliquely to this, so that the gap X and the space 26 extend in the radial direction to a larger diameter.
- the horizontal sectional view of Figure 4 shows the lower cutting device 21 in Figure 3 with its cutting head 27 and cutting bar 28.
- the cutting device consists for example of a flat steel profile.
- Figure 5 shows a partial plan view of a partition wall 4 with a trained as a slot through hole 31 and openings 32 in an enlarged view.
- Figure 6 shows a partial vertical section through the outer wall 30 of the centrifugal drum 2 with welded partition 4.
- the outer wall 30 is in this case provided with a radially inwardly projecting lug 33, on which the partition wall 4 is welded, as shown at 34.
- This type of fastening supply has the advantage that for securing the partition 4 does not have to be welded directly to the outer wall 30 of the centrifugal drum. Rather, the corresponding occurs Welding process on the appropriate approach 33, so that the outer wall is spared.
