Description

The present invention relates to a distribution device for a solids-laden liquid with the preamble features of claim 1. Such a device is made DE 203 08 082 U1 known.

This prior art device has a housing which has perforated discs at its opposite end faces. The first perforated disc serves to introduce liquid and the second perforated disc to dispense liquid from the housing. The exit-side perforated disc is associated with a counter-perforated disc which is arranged concentrically to the perforated disc. The hole pattern of the counter-perforated disc usually corresponds to that of the perforated disc. However, the holes may have different size and / or shape. The respective holes of the perforated disc and the counter-perforated disc can be brought to complete coverage in order to maximize a passage area through the perforated disc and the counter-perforated disc. By moving the two perforated disks relative to one another, the passage area can be reduced starting from this maximum passage area. The reduction results depending on the sectional area formed by the holes of the perforated disc and the holes of the counter-perforated disc.

The prior art device still leaves something to be desired. Thus, the present invention will specify a distribution device of the type mentioned, which can be made easier and which allows a larger throughput. Furthermore, a higher degree of flexibility should be allowed with regard to the throughput through the distributor. Finally, the throughput should be within larger limits and more variable.

To solve this problem, a distribution device with the features of claim 1 is proposed by the present invention.

The distribution device according to the invention has a first counter-perforated disc, which is arranged fixed to the housing. This first counter-perforated disc can be formed for example by a wall of the housing. As a rule, the first counter-perforated disc then delimits the distributor receiving the slurry in which the knife is rotatably driven. There, the first counter-perforated disc is provided stationary. Against the outer surface of this counter-perforated disc, the perforated disc is slidably applied to change the first passage area. This first perforated disc is associated with an adjusting device for changing the passage area. The corresponding adjusting device is mechanically coupled to the perforated disk. The adjusting device may for example comprise a toothed wheel, which meshes with a formed on the perforated disc counter teeth. Alternatively, the adjusting device can also be formed by an actuating cylinder, which is fastened at one end to the housing and at the other end to the perforated disk in order to change its position relative to the housing and thus the passage area.

According to a preferred development or alternatively according to the invention, a second perforated disk is provided, which is assigned a second counter-perforated disk, wherein the second perforated disk and the second counter-perforated disk are displaceable relative to each other for changing the passage area through the second perforated disk and the second counter-perforated disk.

The distribution device according to the invention then has usually on opposite side surfaces of the housing mutually associated perforated discs with counter-perforated discs. On one side lies the first perforated disc with the associated counter-perforated disc. On the other, opposite side, the second perforated disc lies with the second counter-perforated disc. These are usually arranged concentrically with each other. Each unit of perforated disc and counter-perforated disc is assigned a rotatable knife. The two rotatable knives are usually connected to each other with a common drive axle. The knife is preferably provided eccentrically to the perforated disc, so that at the outer periphery of the knife certain holes remain free, whereas other holes are completely covered by the knife and covered with it. The eccentric knife is in itself off DE 20 2011 050 654 U1 known and prevents the clogging of the passage area by the solids entrained by the liquid. On the off DE 20 2011 050 654 U1 Previously known solution can be used in this respect. The disclosure is therefore included in the disclosure of the present application.

Also in the solution according to the invention, the first and / or the second counter-hole surface are each formed by circular discs, which are rotationally connected to the housing. Accordingly, there is a displaceability of perforated disc to the counter-perforated disc by a mobility of the perforated disc relative to the housing.

In the case of two circularly formed counter-perforated discs, these are preferably provided concentrically with one another. This simplifies the arrangement of the rotating blades on a common, arranged eccentrically to the central longitudinal axis of the two counter-perforated discs shaft, which drives the two rotating blades.

In this embodiment, the counter-perforated discs are inside the housing, whereas the perforated discs are provided on the outside of the housing. The two perforated discs are preferably provided with connecting pipes. The connecting pipes are usually arranged as a pipe socket and adapted adapted for connecting hoses, through which the discharged from the housing liquid is discharged.

For recognizability of the respective setting, the first or second perforated disc is preferably overlapped as a circular disc by a flange, which is provided with a scale indicating the passage area. With this scaling a pointer cooperates, which is connected to the perforated disc and accordingly shifts relative to the relative displacement of the perforated disc and the counter-perforated disc relative to the scale.

According to the embodiment according to claim 7, it is possible to adjust the respective partial flows, which are output by the first and the second passage area, individually by adjusting the passage areas. Thus, the mass flow can be adjusted individually on both sides of the distribution device.

The 1 shows an embodiment with a housing 2 whose essential parts are in 1 have been omitted and is basically recognizable only with a housing part, which is an inflow opening 4 Are defined. This inflow opening 4 leads into an annulus 6 that of the shaft of an engine 8th eccentrically interspersed, which is a first knife 10 (see. 2 to 4 ) and a second knife 12 rotating drives. The axis of the engine 8th is eccentric to a first counter-perforated disc 14 or a second counter-perforated disc 16 arranged.

The first counter-perforated disc 14 is an in 1 transparent first perforated disc 18 associated with a variety of first connection pipes 20 is provided with holes of the first perforated disc 18 communicate and surround them. On the opposite side are those with a second perforated disc 22 connected connection pipes with reference numerals 24 characterized.

The first perforated disc 18 is with the first orifice plate 14 with the interposition of a first ring seal 26 connected. This ring seal 26 is between an outer edge of the first perforated disc 18 and a first annular flange 28 clamped. On the first ring seal 26 opposite side is a mounting ring 30 , the fixing screws 32 absorbs through the first annular flange 28 are resisted, and the part of the housing 2 is. The fixing screws 32 protrude not shown slots of the first perforated disc 18 so that the first perforated disc 18 relative to the first orifice plate 14 can be pivoted. The first ring seal 26 takes it through the mounting screws 32 caused compression forces so that the mounting screws 32 held on train and are braced. The fixing screws 32 spring rings may be underlaid against the annular flange 28 abut the ring seal 26 to keep under tension. By adjusting the torque of the mounting screws 32 can the clamping force against the perforated disc 18 acting seal 26 be set in total and distributed on the scale.

For the purpose of a better understanding of the solution according to the invention, the first perforated disc 18 in the range of first holes 34 the first perforated disc 18 shown transparently. So it is clear that in 2 the engine-side, ie first holes 34 only slightly first mating holes 36 at the first counter-perforated disc 14 are omitted, cover. It is understood that the first holes 34 and the first mating holes 36 are provided on equal radii and with the same circumferential division, so that all the first holes 34 completely to cover with the first counter holes 36 can be brought, or the first holes 34 exactly between the second mating holes 36 can be moved so that the passage and thus the effective passage area is laid on the motor side. A corresponding embodiment results for the second perforated disc 22 and the second orifice plate 16 , There are the second holes with reference numerals 38 and the second mating holes with reference numerals 40 characterized.
