- the deflection or distribution rings have on their the bandage end face associated with circumferential circumferential grooves that distribute thedemed ium over the entire kring from the Umlen end face region of the bandage.
- the deflection or distribution rings are each connected via separate pipe connections with the radial inlet and outlet channels.
- the invention is the technical problem of providing a press roll for a roller press of the type described above, which is characterized by an improved cooling concept.
- the invention teaches a press roll for a roll press, comprising a roll core and a cooled or coolable bandage affixed to the roll core, wherein a plurality of circumferentially distributed within the bandage below the (outer) bandage surface (ie the working surface) , Running axially parallel cooling channels are incorporated, which are connected via radially extending inlet and outlet channels with an axial central channel in the roll core, wherein on the roll core at least two each end face connected to the bandage distributor rings are arranged, in which in the circumferential direction
- extending annular channels are arranged, which are connected (each directly) on the one hand with the radial inlet and outlet channels and on the other hand with the axis-parallel cooling channels.
- a press roll is intended in particular for briquetting or compacting and more preferably for hot briquetting or hot compacting.
- the invention also includes press rolls for other purposes, eg. B. for crushing or grinding of granular material.
- the invention is initially based on the knowledge that an effective cooling is achieved by arranged within the drum cooling channels.
- the cooling channels are consequently arranged very close to the bandage surface or close to the pressing tools and / or wear protection layers arranged on the bandage, so that the cooling is realized where the heat is also supplied.
- the distributor rings are provided, in which circumferentially extending annular channels are arranged, which are connected on the one hand with the radial inlet and outlet channels and on the other hand with the axis-parallel cooling channels.
- the distributor rings with the integrated ring channels ensure a perfect distribution of the cooling medium, eg. As the cooling liquid, preferably water or the like. In the course of production can be dispensed with the use of expensive piping systems, steel corrugated hoses or other fasteners. Because of the separately manufactured distributor rings, in which the ring channels are integrated, there is a perfect distribution of the cooling medium.
- the cooling medium passes from the central channel via the inlet and outlet channels oriented in the radial direction into the distributor ring and is there distributed via the annular channel to the individual axis-parallel cooling channels.
- the distributor rings namely waiving separate piping systems, steel corrugated hoses or the like.
- This gel ingt z. B. in that the distributor rings are connected directly to the bandage and to the roll core with the interposition of seals.
- the distributor rings are each arranged in the region of the radial inlet and outlet channels on the roller core, so that they cover the radial inlet and outlet channels.
- the distributor rings fastened on both sides of the bandage consequently extend beyond the radial inflow and outflow channels, so that the distributor rings are directly interposed with seals and without the use of separate tube rings, corrugated steel tubes or The like, can be attached to the roll core and connected to the radial inlet and outlet channels.
- the seals between distributor ring and roll core are particularly preferably annular sealing elements, for. B. O-rings.
- distributor ng and bandage are particularly preferably flat gaskets.
- the embodiment of the invention is characterized by a particularly simple structure and optimized cooling.
- the absence of separate connecting pipes or the like makes it possible to fully exploit the roll width, so that you can work with wider bandages or segments.
- the cooling is also optimized so that, surprisingly, the distributor rings can be connected to the roll core directly, with the interposition of suitable seals, despite the high temperatures without the need for, for example, B. corrugated hoses are required.
- the distributor rings are particularly preferably designed in each case as completely circumferential, one-piece distributor rings, for. B. steel.
- the required channels can be introduced by machining in the distribution rings.
- These separate distribution rings also have the advantage that they can be used multiple times regardless of the bandage, z. For example, if the bandage has to be exchanged after wear. So there is z. B. the ability to fasten the distributor rings only on the bandage (and not on the roll core), z. B. releasably by means of screw.
- the distributor ring can be produced in a particularly simple manner if inner circumferential grooves are provided in the distributor rings, which extend in the inner circumferential direction over at least part of the inner circumference and which form the annular channels with the roll core in the mounted state of the distributor ring. It is therefore not necessary to integrate the ring channels "completely" in the distribution rings, but manufacturing technology
- each distribution ring only a single, over the entire circumference completely encircling annular channel is integrated.
- This has the advantage that only one radial inlet or Abiaufbohrung is then required for each distribution ring, so that the stability of the roll core is only minimally affected.
- a plurality of annular channels can be incorporated in each distribution ring, each not over the entire circumference, but over a certain circumferential angle of z. B. extend 90 ° to 180 ° and the respective separate supply and discharge channels are connected to the central channel. So z. B. are worked with two ring channels per distribution ring, each extending over a circumferential angle of 180 °.
- Such an embodiment has the advantage that the distribution of the cooling medium in particular under the aspect of a uniform distribution and thus a homogeneous
- throttling devices in the cooling channels or in some cooling channels which reduce the flow cross section of individual cooling channels by a predetermined amount.
- the invention is based on the recognition that it is first of all sensible in terms of manufacturing technology to manufacture all cooling channels with the same cross-section. Depending on the geometry of the annular channel and in particular the position of the feed channels, however, an inhomogeneous cooling may then occur since, starting from the radial feed channel, not all cooling channels are uniformly supplied with cooling liquid. This fact can be taken into account in a preferred embodiment of the invention in that some cooling channels are provided with suitable throttling devices.
- These are preferably simple diameter reductions z. B. can be realized by the use of suitable ring elements or diaphragms, which are integrated into the cooling channels or assigned to the cooling channels. Preferably, these elements or panels are not integrated directly into the cooling channels, which are arranged directly in the bandage, but in the adjoining sections in the distributor rings. This can be done in advance by
- the distributor ring is preferably made of steel.
- the bandage can be made of steel, wherein the pressing tools arranged on the bandage and the wear layer are preferably made by powder metallurgy and fixed to the bandage, z. B. by hot isostatic pressing (HIP).
- the cooling channels essential to the invention are therefore particularly preferably used in a bandage whose pressing tools and / or wear protection layer are powder-metallurgically, for. B. by hot isostatic pressing, is produced.
- the invention is preferably realized in a one-piece, completely encircling ring bandage. This is preferably shrunk onto the core.
- the invention also includes other types of attachment, eg. B. gluing or by means of feather keys.
- FIG. 2 shows a simplified axial section (in another sectional plane), the article according to FIG. 1 in a "partially broken" view and a partial section through the article according to FIG. 1 in FIG another view.
