Definitions

  • the present invention relates to a machine for reducing the amount of waste produced by machining.
  • a very important problem for anyone performing machining is currently constituted by the disposal of the sludge produced by said machining.
  • This type of apparatus filters out the oily emulsions and mineral oils from the actual waste chips by means of a screen which is mounted on a conveyor belt above which the machining fluids are filtered.
  • Said screen is usually constituted by a paper roll or, in other cases, by a film made of non-woven fabric or other material having adapted characteristics, so that the cutting fluids can filter out from said waste by gravity.
  • Said cutting fluids i.e., the oily emulsions and the whole mineral oils, are thus collected and conveyed into a tank which lies below said screen to be subsequently reused for subsequent machining.
  • the conveyor belt actuated appropriately, must therefore replace the clogged part of the screen with a new one, conveying the part that is clogged with residues into a collection container for subsequent disposal.
  • the aim of the present invention is to solve the above drawbacks by providing a machine for reducing the amount of waste produced by machining.
  • a particular object of the present invention is to provide a machine which reduces the amount of waste and is simultaneously capable of recovering as completely as possible the fluids that can be reused for subsequent machinings.
  • Another important object of the present invention is to provide a machine for reducing the amount of waste produced by machining which allows to downgrade the waste to be disposed, so as to reduce its impact on the environment.
  • Another important object of the present invention is to provide a machine which by reducing the amount of waste ensures a considerable saving on the costs to be sustained for the disposal of said waste, reducing unit disposal costs.
  • Another important object of the present invention is to provide a machine which separates the liquid part of the waste from the solid part, so as to reduce the weight and volume thereof.
  • Another object is to provide a machine for reducing the amount of waste produced by machining which allows to recover the oily emulsion to dispose it separately from the remaining waste.
  • Another object of the present invention is to provide a machine for reducing the amount of waste produced by machining which can be equipped in practice with per se known equipment and technologies and has a simple structure.
  • a machine for reducing the amount of waste produced by machining characterized in that it comprises a press with a compaction chamber provided with perforated walls, one of which can be opened in order to discharge the compacted material.
  • a machine for reducing the amount of waste produced by machining is generally designated by 10 and comprises a body 11 (housing) which is substantially box-like and is provided, in an upward region, with an opening 12 for accessing a compaction chamber 13 formed inside said body 11.
  • Said machine 10 further comprises a flat presser 14 which can slide alternatively in a longitudinal direction inside said compaction chamber 13 and is arranged, when inactive, above the body 11.
  • Said flat presser 14 is conveniently actuated by a piston 15, which is supported by a frame 16 is provided above the body 11 and is connected to an oleodynamic control unit actuated by a motor drive 17.
  • said compaction chamber 13 has a trapezoidal plan shape, with a bottom 18 and side walls 19 formed by the coupling of a first internal layer, a second intermediate layer and a third outer layer, designated by the reference numerals 20, 21 and 22 respectively, all of which are made of metal plate.
  • First uniformly distributed holes 23 are provided in said first layer 20, while said second layer 21, which is thicker than the first layer 20, is provided with second holes 24 which are conveniently larger than the first holes 23 and are also uniformly distributed.
  • Said third layer 22 also is thicker than said second layer 21 and has third holes 25 which are conveniently larger than the second holes 24.
  • Said body 11 is also provided with a door 26 which is arranged at the side wall 19 formed by the larger parallel side of the trapezoidal plan of said compaction chamber 13.
  • Said door 26 is hinged, at one end, to the body 11 so that it can be opened; a pin 30 prevents accidental opening of the door 26, while the housing body 11 of the machine has a detachable part 31 at said door 26.
  • a removable footing 27 which also is constituted by the coupling of said first, second and third layers 20, 21 and 22 made of metal plate.
  • a hopper with an inclined plane 28 for conveying the waste produced by machining toward the opening 12 of the compaction chamber 13.
  • tray 29 for collecting the liquid part and there is a pump, not shown in the above figures for the sake of simplicity, for emptying said tray 29.
  • the flat presser 14 enters the compaction chamber 13, compressing the waste introduced therein, causing the consequent migration of the fluid part through said first, second and third holes, designated by the reference numerals 23, 24 and 25 respectively, and its conveyance into the collecting tray 29, while the solid part is compacted at the bottom of the chamber 13.
  • the passage for the cutting fluids subjected to the compression of the flat presser 14 is determined by the first, second and third holes 23, 24 and 25, which lead into the collection tray 29.
  • This operation correspondingly substantially reduces the noxiousness of the waste to be disposed, which can thus be sent directly to a landfill.
  • An important advantage achieved with the present invention is the provision of a machine by virtue of which there is a reduced waste of raw material, in view of the considerable amount of whole oil that can be recovered and returned to subsequent machining operations.
  • Another advantage is achieved with the machine according to the present invention in that a machine has been provided which allows, by reducing the amount of waste, to correspondingly also reduce the transportation related thereto, leading to positive effects on traffic, noise pollution and atmospheric pollution.
  • the materials used may be any according to the requirements.
