Definitions
- the invention relates to a device for the production of granules from flowable, viscous masses, which are brought into the form of drops and solidify or gel, consisting of a container charged with the flowable mass with outflow openings which intermittently form drops through a perforated belt which is periodically guided past them be opened or closed.
- Such a device is known from EP 0 134 944 B1.
- an endlessly circulating belt is guided on two deflection drums, at least one of which is driven.
- the band is designed as a plastic band, for example made of PVC, in order to obtain sufficient elasticity during circulation and to rest against the container.
- Plastic straps are subject to relatively high wear and aging. This can mean that a relatively frequent belt change must be provided, which is associated with a loss of production, or that the belt no longer fits tightly against the outlet slot of the container after a long period of operation, so that an insufficient function occurs if the belt tension is not continuously adjusted.
- the invention has for its object to provide a tape that is much more durable and that does not have the problems of resilient tapes.
- the invention is based on the consideration that, of course, metal strips, in particular steel strips, have the desired strip properties, but are only very effective given the relatively small dimensions of the deflecting drums of the devices mentioned at the beginning and because of the flexibility required thereby would have thin strips realized, the openings of which do not have sufficient volume to enable droplet formation.
- the invention consists in the fact that the band is designed as a thin metal band, but is provided on all perforation openings with sleeves projecting towards the side facing away from the container. This configuration enables a sufficiently thin steel strip to be used which has sufficient stability with aging resistance, but the openings of which nevertheless provide a sufficiently large volume for the formation of drops.
- the sleeves can be provided with a collar which bears against the metal strip on the side facing the container, and the interspaces between the collar and the sleeves can be filled with a layer which is flush with the collar .
- This layer can be, for example, a corresponding plastic layer, but in this case it does not need to absorb tensile forces.
- FIG. 1 is a schematic side view of an inventive device for producing granules
- 2 is a top view of the device of FIG. 1
- Fig. 3 is an enlarged view of the section through the perforated tape used in the device of FIGS. 1 and 2 along the section line III-III in Fig. 2, and
- FIG. 4 shows a variant of the perforated tape in a representation similar to FIG. 3.
- an endless circulating belt (2) is guided above two conveyor belts (3 and 4) above a conveyor belt (1), in particular a steel belt designed as a cooling belt, which in a manner not shown above the conveyor belt des (1) are stored in a support frame.
- the deflection drum (3) is driven in the direction of the arrow (5).
- Fig. 2 shows that this is done in that the bearing shaft (3a) of the Umlenktrom ⁇ mel (3) is provided with a gear (6) which is driven by a pinion (7) and an electric motor (8).
- a chain or rubbing, in particular toothed belt operation it is equally possible to use a chain or rubbing, in particular toothed belt operation.
- the two deflection drums (3 and 4) are mounted so that their mutual distance can be adjusted to a certain extent.
- the deflection drum (4) is held in a longitudinal slot (9) indicated by a broken line in FIG. 1.
- the distance between the deflection drums (3 and 4) can be adjusted using a spacer (10) consisting of the two parts (10a and 10b), which is provided with a screw bolt (11). Spacers of this type are provided on both sides of the deflection drums.
- the circumferential band (2) of which a section of the lower strand (2a) is shown in FIG. 3, consists of a perforated metal band, in particular steel band (25), which, as FIG. 3 shows, is very thin.
- This thin steel strip (25) can therefore be placed around and guided around the deflection drums (3 and 4) even with small dimensions.
- the openings (12) provided in the steel strip (25), which are circular in the exemplary embodiment, are each provided with inserted sleeves (26), the collars (26a) of which rest on the side of the steel strip (25) and for example with these are welded, which points inwards when the steel strip (2) rotates.
- the spaces remaining between the collars (26a) of the sleeves (26) are filled with a layer (27), in particular with a plastic layer, so that the inward-facing side of the band (2) has a flat surface points.
- the steel strip (2) rests on the curved outer surface of a tubular body (14), which on the outer surface facing the lower run (2a) is provided with a slot (15) running transversely to the strip (2) which is closed off by the tightly fitting perforated band (2) or, if a row of openings (12) is passed in each case, is released through these openings.
- the tubular body (14) has a guide channel (16) for the supply of viscous and flowable mass, which is supplied in the direction of the arrow (17) in a flowable, in particular heated, state. From this guide channel (16) go from holes that open into the slot (15) formed as an open groove. If the guide channel (16) is therefore charged with the material to be dripped, it can drip into the slot (15) and from there through the sleeves (26) onto the conveyor belt designed as a cooling belt (1). Despite the relatively thin steel strip (25), this is possible because the sleeves (26) provide sufficient volume to absorb a certain amount of the mass coming from the tubular body (14), which is hot in the exemplary embodiment, and then drop-shaped on the surface of the cooling belt (1) where the mass solidifies into small lenticular bodies.
- the tubular body (14) is heated in a manner not shown in detail.
- the entire device is also closed off by a cover (22).
- Direction indicators (14a and 14b) in the form of radially projecting ribs serve to force the product which emerges from the tubular body (14) back onto the inner surface of the band with the openings (12).
- FIG. 4 shows a variant of a steel strip (2) which, as in the exemplary embodiment shown first, is provided with inserted sleeves (26 '), which here, however, have the shape of nozzles which are made from elastically deformable material. These sleeves (26 ') have an insertion bevel
- the sleeves (26 ') can be pressed into the openings of the steel band (25) with their insertion bevel (30) and locked in place with their locking groove
- the layer (27) again ensures that a smooth contact surface is created on the side of the collar (26'a).
