Übersetzung für "Weir plate" in Deutsch

However, a plurality of discharge channels and recesses 29 can also be formed on a single weir plate.

A single discharge channel and a single recess 29 are preferably formed on each weir plate.

Located opposite to the weir plate is a baffle 34 that is attached to a fixed part of the housing of the decanting centrifuge 1 and that does not rotate with the cylinder drum 20 .

The width of a weir gap 33 that is generated between weir plate 32 and baffle plate 34 can thus be varied even at a rotating cylinder drum 20 .

This leads to the advantage that the advantageous properties of such an overflow weir 21 on a weir plate 19, in accordance with the present disclosure, are maintained.

It is in accordance with the present disclosure, advantageous when the weir plate 19 and the deflecting device 23 are materially connected with one another and thereby form a constructional unit.

This can be achieved, according to an embodiment of the present disclosure, in such a way, for example, that the deflecting wall is disposed partly directly in axial extension of the region of the passage opening not covered by the respective weir plate axially outside before the passage opening, and axially partly or fully covers the opening.

It is also known, for example, from U.S. 2004/0072668 A1 or WO 2008/138345 A1,to arrange a housing instead of an overflow weir on the weir plate of the passage opening, with the overflow weir or a nozzle being then arranged in an oblique side of the housing on the passage opening.

The deflecting device is, accordingly, arranged in such a way, for example, on the weir plate, that, by maintaining the overflow weir, an exiting fluid flow is subjected to a twist in the circumferential direction at the overflow edge in the axial extension of the passage opening.

After the discharge from the weir plate 32, the liquid phase 54 is thrown radially towards the outside due to the high centrifugal forces.

The publication “Patent Abstracts of Japan”, number 11179236 A, in contrast discloses that guide plates can be associated with outlet ports in the drum cover, which are partially closed off in each case by a weir plate forming an overflow weir, which guide plates impart a swirl to the liquid discharging from the drum, wherein the repelling effect that occurs is to be utilized for saving energy.

It is also known—for example from US patent document US 2004/0072668 A1 or PCT International patent document WO 2008/138345 A1—to arrange a housing instead of an overflow weir on the weir plate of the outlet port, wherein the overflow weir or a nozzle is then formed at the outlet port in an inclined side of the housing.

As already explained, the three guide plate pieces 31 a, b, c and the weir plate 25 itself together form the discharge channel which is open toward the rotational axis D.

Also to be referred to as being very advantageous is that the area of the recess 29 up to the inner edge 25 a of the weir plate 25 should preferably be smaller, especially by 25% or more smaller, preferably 30% smaller, than the imaginary cross section—the imaginary cross-sectional area—of the discharge channel in the region of the overflow edge (which in the main can be calculated as the product of the width of the bottom by the height of the discharge channel) which is defined by the height of the guide plate piece 31 a in the region of the overflow edge 31 k .

According to German patent document DE 10 2010061 563 A1, the weir plate has a material recess forming at least a part of a discharge channel or a complete discharge channel, wherein the discharge channel is designed in such a way that it deflects in a suitable manner flow discharging from the drum.

The liquid in contrast flows toward the larger drum diameter at the rear end of the cylindrical section of the drum 3 and is diverted there over a weir having outlet ports 15 in a drum cover 17, wherein a weir plate 19, which is attached on the outer side of the drum cover in a radially adjustable manner in this case, is associated with each outlet port 15 .

The discharge weirs 23 again have in each case a flange-like weir plate 25 arranged on the drum cover.

The guide plate section 31 a and also two guide plate pieces 31 b, c, forming the bottom, together serve, in conjunction with the weir plate 25, for deflecting a liquid flow, discharging axially from the drum through the recess 29, essentially against the direction of rotation K in the direction ?K, which as a result of the additional driving effect in the circumferential direction produced by the deflection leads to a favorable operation from the energy point of view.

Such internal fitments may be baffle plates, weirs or hollow spirals.

The guide plates are attached to the outside of the overflow weir on the weir plates, for example.

The guide plates are attached on the outer side of the overflow weir, for example on the weir plates.

A typical sieve plate column suitable for use in carrying out the present process may comprise e.g. 5 to 20 sieve plates with or without discharge weirs, the plates being arranged so as to be spaced apart from each other at separations which increase from below to above, the two uppermost plates being spaced apart from one another at a separation which is 10 times the separation between the two lowermost plates.

It is, therefore, advantageous that an embodiment according to the present disclosure leaves the overflow weir directly on the weir plates on the drum cover, and only the fluid which has already left the rotating system via the overflow weir will be deflected in the circumferential direction.
