Definitions

  • the invention relates to a tempering machine for lumpy goods, in particular dryers or pasta dryers, with a drum, with a plurality of chamber elements, which have: conveying devices for the goods; side walls facing adjacent chamber elements; an outer wall having a first screen hole wall; and an inner wall opposite the outer wall and having a second screen hole wall.
  • a temperature control machine If we are talking about a temperature control machine, it should be expressed that such a machine is of course also suitable for cooling and in general for any type of heat or cold treatment. Therefore, the use of such machines is not limited to pasta, but could also be used for the heat treatment of fruits (e.g. nuts or beans of all kinds) or for mineral, lumpy goods.
  • Such a temperature control machine is known from FR-A-888 387.
  • the drum of the known temperature control machine has an outer wall lying on the outer circumference, an inner wall lying on the inner circumference and a plurality of dividing walls which radially connect the inner wall to the outer wall and which divide the area between the inner wall and the outer wall into individual chamber elements.
  • the outer wall of each chamber element like the inner wall of each, has a tightly screwed sieve.
  • a drying drum with sector-shaped pocket trays is known from DE-C-320 526.
  • the drum consists of a frame, which in cross section has approximately the shape of a spoked wheel.
  • sector-shaped pocket trays can be inserted interchangeably into the sector-shaped pockets located between the spokes.
  • the pocket trays are provided with perforated perforated walls and have a flap attached to the front by hinges.
  • This known rack dryer is designed without a conveyor. The dry goods must be introduced through the flap in the front.
  • each chamber element In a drum dryer for pasta known from IT-A-512 118, the conveying device in each chamber element consists of a type of screw formed by correspondingly shaped walls, which is, however, immovably arranged in the chamber element and only rotates eccentrically around the drum axis with each drum revolution .
  • the result was that the general cargo moved under the action of gravity along the screw gears, which brought about a gentle conveying, which avoided the risk of crushing and excessive abrasion.
  • pasta dryers have also become known in which a driven screw is provided within each chamber element. In this case the chamber element was mostly cylindrical.
  • each chamber formed a channel for the dry air, which generally flowed across the drum.
  • the screen wall of the outer and inner circumference of the drum was fixed to the chamber housing. In the case of sticking, access to the interior of the housing was therefore difficult, so that cleaning could hardly be carried out in practice.
  • the invention has for its object not only to provide easy access to the interior of the chamber and thus to facilitate cleaning, but also to enable easy handling for this purpose. Another goal is to make assembly easier.
  • this is achieved in a tempering machine set out at the outset in that the chamber elements for forming free spaces between the chamber elements have a cross-sectional shape that deviates from a sector shape and the first screen hole wall can be detachably fixed in a closed position by a holding and tensioning device arranged in these free spaces and in one Open position can be brought.
  • a special perforated screen wall is preferably provided for interacting with the holding device mentioned, which is characterized in that it has at least at one end at least one opening for the engagement of a holding device.
  • This sieve-side holding device then interacts with the machine-side holding device and / or with the tensioning device.
  • a drum 1 is mounted in a drum housing 2 in a manner not shown.
  • the drum 1 is divided at predetermined, preferably uniform intervals by drum shields 3 (hereinafter also referred to as shields 3).
  • drum shields 3 On the side of the drum housing 2, each of these drum shields is opposite an intermediate wall 4 which closely surrounds the shields 3.
  • the shields 3 can be pushed into the opening 5 of the partition 4 surrounding it, or the partition 4 is divided and is only completed after the shield 3 has been inserted.
  • the shields 3 may have a groove and / or a spring on their outer circumference, which engages in a corresponding groove or shape of the intermediate wall 4, so as to provide a better seal between the shields 3 and the intermediate walls 4 to achieve treatment chambers 24 formed.
  • the shields 3 and / or the partition walls 4 are made up of several layers, of which individual layers protrude corresponding to a spring or form a depression.
  • the drum 1 receives a number of box-shaped chamber elements 6 on its circumference.
  • Each chamber element 6 contains a conveyor device which can be driven in the manner described at the beginning or can also be operated only passively by the rotation of the drum, but which in any case transports the goods to be treated, generally pasta, at a uniform speed over the length of each chamber element 6.
  • the chamber elements 6 are aligned in mutually adjacent and separated by a shield 3 drum sections so that the material to be dried at the end of a chamber element 6 of the (refer to Fig.1) rear drum section passes through one of the openings 7 and from there falls into a chamber 6 of the front drum section.
  • the material to be dried then passes through the corresponding chamber element 6 in the front drum section and exits again at the foremost plate 3, with corresponding discharge devices being provided for the dried material.
  • Such devices are known from the prior art and therefore do not need to be explained in detail. It should only be pointed out that it is also known to remove the dried material from the inside of the drum, which is also within the scope of the possibility here.
  • the screen fabric 8 delimiting the inner circumference of the drum somewhat narrower, so that there is enough space between its edge and the adjacent plate 3 to prevent the dried material from falling down on the underside of each chamber element 6 and on the edge thereof to allow attached outlet opening.
  • the outlet opening can also be arranged in the region of the outer circumference of the drum 1, the dried material falling out being collected below the drum 1.
  • the sieve fabric 8 delimiting the inner circumference of the drum 1 is placed over rods 9 which are each fastened between two shields 3.
  • the inner screen wall consists of a single screen fabric 8 which is common to all the chamber elements 6 arranged on the drum 1, a particularly advantageous embodiment is shown for the outer screen wall.
  • Each chamber element 6 is assigned a separate sieve wall 10, which is held taut at its lateral ends by means of inserted rods 11 on the housing of each chamber element 6. How this is done in detail will be explained later with reference to FIGS. 3 to 5.
  • the drum 1 is permeable to air transversely to its axis due to its design with sieve walls on the inner and outer circumference, so that a treatment gas, generally hot air, for example on the bottom according to the arrow 12 is blown into a treatment chamber 24 and on the top, for example via a discharge pipe 13, can be removed. Examples of the guidance of the treatment air are explained below with reference to FIG. 2.
  • FIG. 2 and the following figures parts with the same function are designated with the same reference symbols, parts with a similar function are also identified, but with the addition of a hundred digit. Accordingly, it can be seen from Fig. That the drum housing 2 is jacked up on a frame 14. In order to facilitate access to the interior of each treatment chamber 24 or to the drum 1, the side walls 15 of the drum housing 2 can be opened in the manner indicated by arrows. For this purpose, hinges (not shown) are provided on the top of the drum housing 2. Furthermore, it is indicated how the material 16 to be dried is circulated in the chamber elements 6 when the drum 1 rotates, and it is understandable that during this circulation the material 16 is transported along the screw flights already mentioned.
  • each treatment chamber 24 has at its front Intermediate wall 4 'has an inlet opening 20 and an outlet opening 21 on its rear intermediate wall 4. A connection to the adjacent treatment chambers can be established through these openings 20, 21, provided these openings 20, 21 are not closed.
  • the flow path for the through-air operation is given by the axis of the tubes 23 and 13 or the openings 20 and 21. This ensures that air is passed through the chamber elements 6 in the upper and lower quarters of the drum 1 in the through-air mode. But precisely in the upper and lower quarters, the screen hole walls 10 of the chamber elements 6 are completely covered by the material 16, so that it is ensured that the air cannot pass the material essentially ineffectively. However, even with a narrow construction of the treatment chamber 24, there is still enough space on the side to allow the through-air to escape.
  • FIG. 3 shows a first embodiment of box-like chamber elements 106 distributed over the circumference of the drum, which - viewed in cross section - have approximately a polygonal shape.
  • the wall section 25 facing the respective adjacent chamber element 106 is kinked and extends in such a way that a radially inward section 26 runs parallel to the corresponding wall of the adjacent chamber element 106. This measure ensures that a negligibly thin gap remains between adjacent chamber elements 106, and thus the air is forced to flow through the inner screen hole wall 8, to wash the material to be dried inside each chamber element 106 and ultimately on the outer screen wall 110 to resign.
  • the radially outward part 27 of the wall section 25 forms an angle with the part 25 in such a way that a free space 28 is formed between mutually opposite sections 27 of adjacent chamber elements 106.
  • This free space 28 serves to accommodate a holding device and a tensioning device for each of the screen hole walls 110 assigned to only one chamber element 106.
  • each chamber element 106 can extend in the form of a slot from a central wall 30 to the lateral wall section 25. This gives the outlet opening 29 a shape deviating from the rectangular shape. Therefore, in order to supply the dry material to a (in the manner shown) rectangular outlet opening 29, an inclined wall 31, indicated by a broken line, can extend from the side wall section 25 to the outlet opening 29.
  • the inner perforated screen wall 8 may be placed over cylinder brackets (not shown) defining the inner circumference of the drum 1, so that it has a substantially completely cylindrical surface.
  • the housings of each chamber element 106 are concavely shaped on their side resting against the screen hole wall 8, as can be seen from FIG. 3. It is understood, however, that with such a design, the individual chamber elements 106 must be tensioned very strongly against the inner screen hole wall 8 in order to prevent slit formation.
  • the tensioning device for the radially outer screen hole wall 110 which will be described below, can simultaneously act as the tensioning device which causes the inner screen hole wall 8 to be pressed against the housing of each chamber element 106.
  • a rectangular frame (see FIG. 1), which extends over the entire housing of the chamber element 106, is provided, which consists of two rods 11, 111 and a spring clip 32 at each end of a chamber element 106 .
  • the chamber element housing can have a small cutout on the upper side, but each drum shield 3 can also be provided with a corresponding lateral groove.
  • the arrangement of spring clips 32 helps to keep the screen fabric forming the screen hole wall 110 taut. Since the chamber elements 106 can be made relatively long in the manner shown in FIG. 1, it may be expedient to also provide additional spring clips 33 between the opposite ends of each chamber element 106, which protrude beyond the screen hole wall 110.
  • Each spring clip 32, 33 can be pivoted about an axis 43 such that it can move from the closed position shown in FIG. 3 by means of the central chamber element 106 to the open position shown by means of the right-hand chamber element 106. In this open position, the screen perforated wall 110 may be loose in the manner shown, but depending on the selected deflection of the spring clip 32, it can also be tensioned by its inherent elasticity.
  • a tensioning device which in the simplest case consists of a tension spring 35.
  • a tension spring 35 engages on an anchoring pin 36 fastened to a drum shield 3 (cf. FIG. 1) and is hooked on to the other end on the rod 11 forming the holding device together with the rod 111.
  • This construction ensures, on the one hand, that the outer screen hole wall 110 is always tensioned and bears against the housing of each chamber element 106 without any gap formation. In addition, this construction ensures that the screen hole wall 110 can get into its open position by simply unclamping the tensioning device 35 and so that each individual chamber element 106 is easily accessible for cleaning purposes is. Furthermore, a single chamber 106 can also be easily removed from the drum circumference in this way, so as to clean the inner screen hole wall 8.
  • the new insertion of an individual chamber element 106 is additionally supported by the polygonal shape shown, because the approximately radially running wall sections 26 of the adjacent chamber elements act as guide and orientation surfaces. It also has a relief if the anchoring parts 34, 36 are arranged along a radial line 37.
  • FIG. 4 shows how a screen fabric 310 can be arranged on a chamber element 6, for example as an inner screen hole wall, by tension springs 35 acting on a reinforced fabric edge 51.
  • the inner screen hole wall does not necessarily have to be formed by a screen fabric that is common to all chamber elements, but that this inner wall can, if appropriate, be configured exactly as has been described with reference to the outer screen hole wall 10 and will be described below will be.
  • at least the outer screen hole wall 10 is preferably divided into a plurality of angular sections over the outer circumference of the drum 1, a separate screen hole wall preferably being associated with each chamber element.
  • the screen fabric 310 is first suspended in the springs 35.
  • the chamber element 6 is then inserted between two stops 52 attached to the shield. If necessary, the stops 52 can have funnel-shaped bare cones for more precise orientation of the chamber 6.
  • the outer sieve 10 is then placed over it and pulled down with the aid of quick-release fasteners 53 which are suspended in the holding rods 11 and are anchored to the shield 3. In this case, the quick-release fasteners 53 are pulled against the action of the tension springs 35, which tension themselves more strongly until counter-stops 54 provided on the chamber element housing abut against the stops 52.
  • the tension springs 35 cooperate with the tension locks 53 to form a common tensioning device for both screen hole walls 10, 310, the stops 52, 54 acting as orientation devices ensuring that the inlet and outlet openings (see the opening 29 in FIG. 1) exactly aligned with the openings 7 of the shields 3.
  • the funnel surfaces already mentioned on the stops 52 can contribute to the lateral alignment, just as the stops 52 are arranged as closely as possible on the side wall sections 225 of the chamber element housing.
  • the chamber element 6 is shown in the embodiment according to FIG. 4 in the open state and has walls consisting of five surface sections in a known manner. While the lower surface section 55 extends essentially perpendicular to the longitudinal axis of the chamber element 6 over both chamber halves separated by the central wall 30 (see FIG. 6), the darker hatched section 56, which extends to the left, extends from below and further inwards (with reference to the level of the drawing) upwards and outwards until after a pitch of the screw formed in this way, a wall 57 located in a parallel plane to the wall section 55 follows.
  • an obliquely inward, lightly hatched wall section 58 (cf. FIG. 6), which is followed by a wall section 59 parallel to it at a distance from the wall section 57.
  • the top and bottom of the housing of the chamber element 6 is expediently rounded in order to apply a more uniform tension to the respective screen fabric 10 or 310. This rounding can be done according to a circular arc, but the best equalization results when training along a parabolic arc.
  • FIG. 5 illustrates further possible designs using chamber elements 306, 406 and 506, of which the chamber element 406 can be seen in a side view together with a drum shield 3 from FIG. 6.
  • the chamber element 306 has an embodiment of the passive, ie. only by the rotation of the drum acting conveyor device of the type known from IT-A-427 072.
  • the chamber element is divided by a number of partition walls 60, which are inclined by inclined, channel-like conveyor chutes 61.
  • the material to be dried slides down a conveyor trough 61 and, at the next half turn of the drum, reaches the upper region, from where it slides into the next chamber element via the adjacent conveyor trough.
  • the housing of the chamber element 306 can be provided with handles 62, on which schematically indicated tensioning fasteners 53 (see FIG. 4) designed in a known manner act.
  • the chamber element 306 is brought into its aligned position with the chamber elements on the other side of the respective shield, stops 154 again corresponding to the stops 54 in FIG. 4 (only one stop 154 is shown) can be provided.
  • the stop 154 is in FIG. 5 shown in an exploded view because it fulfills another function.
  • a tension spring 35 for engagement with a holding rod 11 of the outer screen hole wall 10 can be anchored to it.
  • the holding rod 11 at the other end, or the holding rod 11 is combined with the handle 62 on the right-hand side (with reference to FIG. 5), as a result of which it also has a double function there for the attack of the tension lock 53 there exercises, which on the other hand has the consequence that the sieve 10 can only be detached from the chamber element 306 after the rod has been removed from its holder on the handle 62.
  • This example shows that the respective screen hole wall does not necessarily have to be attached to a holding device of the shield, but that the holding device can also be provided on the chamber element itself.
  • the stop 153 is assigned a corresponding counter-stop (not shown).
  • a possible embodiment of the funnel-shaped side flanks of such a counter-stop 152 is shown on the chamber element 406. However, in this embodiment it acts only as a centering aid because a stationary counter-stop 252 is welded to the shield 3 in the manner shown in FIG. 6.
  • This counter stop 252 interacts with a stop 254 which is fixedly connected to the chamber element housing and is provided with an angled plate 63.
  • This plate 63 has a slot-shaped opening 64 into which a pawl nose 65 engages.
  • the pawl nose 64 is formed on a spring arm 66 which is attached to the counter stop 252.
  • the lower surface 67 of the nose 65 is slightly beveled, so that manufacturing tolerances are compensated for and this surface 67 is in any case in contact with the lower edge of the opening 64 (cf. FIG. 5).
  • the chamber element 406 is fixed in a position in which the two stops 252, 254 abut one another.
  • the latch nose 65 which forms a snap lock, only needs to be pulled out of the opening 64 of the plate 63.
  • the pawl 65 can be assigned a locking device in order to hold it in the open position against the action of its spring arm 66.
  • FIG. 6 is only a particularly advantageous example, in which the individual chamber elements 6 or 406 can be loosened or attached quickly to the associated drum shields 3 due to the quick coupling device shown.
  • the centering device shown With the aid of the centering device shown, not only a correct fit can be ensured, but in the end also a relatively rigid construction, in which the chamber elements 6 form the stiffening ribs between the shields 3.
  • another type of releasable connection for example a screw connection, may be preferred.
  • no or only a weaker supporting structure is required.
  • this modular arrangement not only makes assembly easier, but there is also an expansion option for each machine, so that production and storage are also simplified and less expensive.

  • the chamber elements 506 show how the sealing effect in the region of the mutually parallel and approximately radially extending side wall sections 126 can be improved by designing it as a type of labyrinth seal.
  • the wall section 126 pointing to the right has bulges 68 which engage in corresponding notches 69 in the adjacent wall 226.
  • This wall design not only improves the sealing effect, but at the same time also fixes each chamber element 506 in its seat with respect to the adjacent chamber elements, so that the arrangement becomes more stable.
  • the bulges 68 and the depressions 69 (which do not necessarily have to be triangular, but can also have a different shape, for example a wave shape) represent reinforcing beads for the side wall sections 126, 226, so that these wall sections can optionally be formed from weaker material. This not only saves costs, but also reduces the overall weight of the machine. In order not to jeopardize the removal of individual chamber elements 506 if the toothed sections 126, 226 are too strongly interlocked, these beads 68, 69, which preferably have a rounded shape, should have an opening angle ⁇ which is greater than 45 ° and, for example, approximately 60 °.
