Definitions

  • the present invention relates to an improved framework for supporting droppings in tunnels or galleries for drying the same droppings.
  • Drying tunnels are constructions wherein the droppings, supported on suitable multilevel frameworks, remain in order to be dehydrated to an appropriate and required level of moisture in view of its reuse as fertiliser for farmland, ingredient of fodder for livestock etc.
  • the surfaces of the framework for supporting the droppings generally consist of conveyor belts which are driven to rotate during the operations of loading and unloading of the droppings.
  • the droppings coming from the farm are generally unloaded on the upper conveyor belt and from there are then sent to the one below and so on to the next ones until they reach the lower surface from which, after the drying process has been completed, they are unloaded outside of said tunnel.
  • Ventilation of droppings performed in known drying systems involved the blowing of air taken from the outside environment at one end of the tunnel and expelling of the air at the opposite end of the tunnel towards the outside.
  • unevenly dehydrated droppings are obtained which particularly in the case wherein they have to be processed later, for example in the case of use as raw material for animal fodder, creates problems in the subsequent processing phases of the same, and does not enable a final product with acceptable features to be obtained.
  • the ventilation air does not reach all the surfaces of the support framework evenly; the higher and lower surfaces may not be reached by a sufficient quantity of ventilation air.
  • the object of the present invention is that of providing a framework for drying droppings which can be used in a drying tunnel with which high drying yields are achieved without spreading unpleasant odours or incurring high building costs and overheads.
  • equipment or a framework for storage and ventilation of droppings in a droppings drying tunnel comprising a support structure for a plurality of longitudinally extending surfaces for supporting and holding droppings, wherefrom said droppings are periodically loaded and unloaded, and means of ventilation of the droppings, characterised in that said means of ventilation of the droppings comprise for each surface for supporting and holding the droppings a respective set of ventilation blades longitudinally aligned one with the other and evenly distanced along said support and holding surface, and means for driving the movement of said blades for ventilating the air inside said drying tunnel over the droppings of the respective support and holding surface.
  • the arrangement on each surface for holding the droppings of means for ventilating the droppings using air inside said drying tunnel due to the fact that cold air taken from the outside environment is not used and said air is not expelled towards said outside environment, provides a high drying yield of the droppings in every season of the year and prevents unpleasant smells from being spread outside of the tunnel.
  • means for ventilation of the droppings in particular in the form of ventilation blades evenly distributed along the support and holding surface, provides even and homogeneous drying of all the droppings inside the drying tunnel.
  • Fig. 1 illustrates a drying tunnel 12 containing the framework 14 for supporting the droppings.
  • the droppings are the result of defecation by poultry.
  • the tunnel for drying droppings of the present invention has been devised with reference to a poultry plant, nevertheless it could also be used in any other type of animal breeding farm or in another situation wherein dehydration or drying of a material is required.
  • Said framework for supporting droppings comprises several surfaces 16 for holding the same droppings and, as shown in greater detail in Fig. 2, a support structure 13 composed of uprights 14, longitudinal rods 17 and cross members (not shown in the figures).
  • the droppings support surfaces 16 consist of conveyor belts which are driven to rotate by suitable drive means not shown in the figures during the operations of loading and unloading of the same droppings.
  • the droppings coming from the farm 18 are transported via suitable belts and conduits 20 and are unloaded on the upper conveyor belt of the framework and from there are then moved to the underlying belt and so on to the next ones up to the last conveyor belt situated in the lowest position of the framework.
  • each belt 16 has a portion 16' projecting from the framework and suitable for receiving by falling the droppings transferred from the upper belt.
  • said framework for drying the droppings 14 is provided with suitable means for ventilation over the droppings of air inside the drying tunnel.
  • said means for ventilation of the droppings comprise a plurality of longitudinally aligned blades 30 above the unit for storage of the droppings to be dried.
  • said blades 30 are shown also in a dotted line in order to give an example of the reciprocating motion they perform.
  • each blade 30 is attached to the support framework, more particularly to longitudinal rods 17 thereof, so as to rotate freely around an axis transverse to the longitudinal axis of said storage unit and are moved by suitable means for actuating said blades according to a backward and forward reciprocating motion whereby air is sent, at the temperature of the air inside the tunnel, over the droppings being dried.
  • Said blade 30 has a transverse bar 34, connected rotatingly to the rods 17 by means of pins 36, and a first and a second panel for churning the air 38, which panels are arranged coplanar and adjacent one with the other and which are embedded by one of their upper ends in an appropriate transverse slot of the bar 34. Said panels are separated one from the other by a narrow central space 40.
  • each set of blades 30 comprise a long longitudinal rod 42 which extends into the central space 40 for separation of said panels 38 of said blades 30.
  • the blades 30 are attached to the rod 42 by means of a cylindrical block 44 having two opposite layers 46 which contain the rod 42 and are moved close one to the other, blocking the rod 42, by means of suitable screws 48.
  • Said cylindrical block 44 is in turn fixed rotatingly to the transverse support bar 34 by means of a pin 50.
  • each drive motor has a respective drive shaft 52' and 54' which extends vertically and which drives respective rods 42 for moving the blades.
  • the shaft 52' of the motor 52 via suitable transmission parts 52'', drives the rods for moving the blades for ventilation of the droppings of the first, third, fifth and seventh surfaces for holding the droppings
  • the shaft 54' of the motor 54 via suitable transmission parts 54'', drives the rods for moving the blades of the second, fourth, sixth and eighth surfaces for holding droppings.
  • the drive motors 52 and 54 are actuated in such a way that they impose opposing and synchronous movements on the respective sets of blades.
  • an effect of compensation of the actions which said ventilation systems discharge on the support structure is obtained.
  • the support structure is thus not involved by longitudinal oscillations which would otherwise be possible if the blades of all the surfaces were moved synchronously in the same direction.
  • the structure must not therefore be anchored to the tunnel and the resistant sections thereof must be appropriately dimensioned with smaller sizes, thus entailing lower construction costs of the system.
  • each rod 42 at the opposite end to that of driving is attached to the framework of said battery by means of a return spring 68 which pushes against a transverse rod 69 of the framework.
