Definitions

  • the invention relates to an atomizing nozzle with a first flow channel with an annular cross section for guiding a medium to be atomized, which is delimited by two radially spaced walls and which opens into an annular nozzle opening, and with a second flow channel surrounding the first one for guiding one gaseous spray medium, which also opens into an annular nozzle opening.
  • Such an atomizing nozzle is known for example from DE 197 49 071 AI. Such atomizing nozzles are used to spray a medium to be atomized, usually a liquid, sometimes also a powder, using a gaseous spray medium.
  • the medium to be atomized is transported under pressure through the annular or gap-shaped flow channel to an annular gap-shaped nozzle opening.
  • This first annular flow channel is surrounded by a second also annular flow channel and this also opens adjacent to the first flow channel in an annular or gap-shaped nozzle opening.
  • such nozzles spray axially or more or less laterally out of the axial axis with an ever increasing spray angle, with spray angles of up to 180 ° and a wrap angle of 360 ° around the muzzle head.
  • Such nozzles are widely used in devices for treating particulate material, for example for granulating or coating these particles.
  • a sticky liquid is sprayed, which serves to glue the particles into larger agglomerates, i.e. the desired granules.
  • Such apparatuses are used primarily in the pharmaceutical industry, where tablet ingredients that are produced as fine dust powders are granulated into manageable powders, for example tablets that can be compressed into tablets.
  • pellets or finished granules or even whole tablets are provided with an outer coating layer.
  • the nozzles spray vertically upwards, that is to say they are designed as standing nozzles, spray at an angle, horizontally or, in some cases, vertically from top to bottom.
  • Such atomizing nozzles are used to spray suspensions, dispersions or solutions and these are also to be used in so-called "hot-melt” processes in which wax melts or hard fat are processed under the influence of heat.
  • the annular flow channels work with liquid cross sections that are in the range of ⁇ 0.25 mm.
  • the material to be treated is swirled or moved around the nozzle, so that an irregular treatment result is then achieved in the case of a nozzle spraying unevenly due to blockages.
  • the object is achieved in that the walls surrounding the first flow channel are rotatable relative to one another about a longitudinal axis of the nozzle. are. It was found that with such a configuration of the gap-forming walls, a centrifugal and radial, ie toroidal movement occurs in the annular gap.
  • the medium to be atomized, which is conveyed in the axial direction through the annular gap, is also set into a rotating movement by the walls rotating relative to one another, which results in the aforementioned toroidal movement.
  • the rotary design of the liquid gap achieves a certain size reduction of such solid clumps, which would otherwise lead to a blockage of the liquid gap with standing walls.
  • a kind of self-cleaning effect is achieved through the rotary configuration, so that ultimately the medium to be atomized leaves the annular nozzle opening in a uniformly distributed manner.
  • the two walls are also axially displaceable relative to one another, as a result of which the gap width of the nozzle opening of the first annular flow channel can be changed.
  • a significant, considerable advantage of this axial displaceability is that the width of the annular gap is self-regulated over a certain bandwidth.
  • annular gaps in such atomizing nozzles have a width of 0.1 to about 0.25 mm, and it is desirable to be able to drive out 1 to 5 grams of medium to be sprayed per millimeter of length of the gap.
  • the axial mobility makes it possible, depending on the nature of the medium to be sprayed, that the gap height adjusts itself. If a certain medium is carried through the first flow channel at a certain pressure, intrinsic properties, for example in the case of a liquid, its viscosity, in the case of emulsions, its flowability and viscosity, exert a considerable influence on the amount that can pass through per millimeter of a gap. In other words, there are liquids that are relatively easy to drive out through such a gap, but others require a slightly wider gap for the same amount of discharge.
  • the gap width adjusts itself to an optimal value under given boundary conditions, that is to say the nozzle regulates itself.
  • the possibility mentioned at the beginning of closing the nozzle mouth of the first flow channel in the idle state can be achieved, for example, when the nozzle is at a standstill by that the at least one movable wall sags due to gravity and thereby the closing movement takes place.
  • this movement can take place by means of a spring force or other mechanisms.
  • conveyor elements are arranged at least on one of the walls which can be rotated relative to one another and which control a movement of the medium to be atomized which is transported to the nozzle opening.
  • these conveying elements can also serve as mechanical means in order to transport any lumps of solid that are carried along in a targeted manner and to crush them if necessary.
  • one wall is stationary and the other wall is rotatable.
  • this measure has the advantage that only one of the two walls has to be moved, and accordingly only drive elements corresponding to these walls have to be present.
  • one wall is stationary and the other wall is axially displaceable.
  • the wall that is rotatable is also axially movable at the same time.
  • this measure has the advantage that the precautions of both the rotatability and the axial
  • the axial mobility is controlled by the conveyed medium to be atomized itself.
  • This measure allows the aforementioned self-regulating effect of the gap width of the nozzle opening of the first flow channel.
  • the axial displaceability is designed such that the nozzle opening of the first flow channel is closed in the idle state.
  • the axial displaceability takes place against a restoring force which moves the displaceable wall (s) into the closed position of the nozzle opening.
  • gravity can be used as the restoring force, so that when the nozzles are stationary, the one movable wall is moved into the closed position by gravity relative to the other.
  • the axially displaceability of the walls is designed such that the nozzle opening of the second flow channel is also closed in the idle state.
  • This measure has the advantage that both nozzle openings are closed in the idle state.
  • the rotatable wall carries a fan on the outside of a head of the atomizing nozzle, by means of which the head can be freed from any buildup in the region of the nozzle openings.
  • a problem that crops up again and again is the contamination of the muzzle head due to mostly uncontrolled secondary air movement, which occurs in the vicinity of the liquid or spray gap. Due to the high blow-out speed, negative pressure areas are formed, which attract vagabonded, sprayed liquid droplets and deposit them on the muzzle head. Therefore, there is an agglomeration or gradually build-up of dried solid from the sprayed liquid.
  • the rotatability of the wall according to the invention can not only be used to create optimal conditions inside the nozzle, but this rotating movement can at the same time be used to avoid buildup on the outside of the head.
  • the one wall is designed as the outside of a central spindle, which is rotatable. This measure has the constructive advantage that the rotating wall is created by a structurally simple means, namely the central spindle.
  • the conveyor elements are designed as impeller sections.
  • This measure has the advantage that a particularly uniform promotion of the movement of the medium to be sprayed is possible.
  • impeller sections are formed on the outside of the above-mentioned central spindle, on the one hand, it is extremely simple to construct and it is possible to achieve particularly favorable and targeted conveyance.
  • the length and number of the impeller sections that is the number of conveying wheels and their cross-sectional shape, can also be varied so that media which are particularly problematic to be sprayed can also be dealt with.
  • the spindle is driven by a pneumatically operated motor.
  • this measure has the advantage that a gaseous medium for spraying the medium to be sprayed will be passed through such a spray nozzle, that is to say it is connected to a source of spray air, usually compressed air. This means that parts of this air can also be used at the same time to operate the motor, which ensures the rotary movement between the walls.
  • the spindle is plugged onto a drive pin, which allows the spindle to move to a certain extent.
  • this measure has the particular advantage that both the spindle can be rotated and, to a certain extent, axially movable due to these dimensions.
  • the degree of mobility can be limited, for example, by a connecting cross pin that runs in an elongated hole in the drive pin.
  • the fan sits on the head of the spindle.

  • the plug connection is such that there is also a certain axial mobility of the spindle 22, the meaning and purpose of which will be described later in connection with the mode of operation.
