Definitions

  • the subject of the present invention is a device for separating hard elements for mill used in the field of the food industry and more particularly the cutting meat.
  • grinders each essentially comprising a feed hopper opening into a chamber where a auger which pushes the meat towards one or more sets cutters each consisting of a star-shaped knife to several branches, curved or not, and a grid presenting more or less large openings.
  • the knife can spin freely on the grid and possibly in the two grids which surround it if it is the case, the said grid (s) being able to be immobilized in the crusher, while a tree is able to drive in rotation the knives it crosses, being linked to them at rotation through at least one flat, while one of its ends is linked to a motor means and that the other end swivels in the landing of a grid support or cross.
  • the most effective of these devices consists of a grid associated with a separating knife which also has the shape a star with several branches, curved or not, each having parallel ribs on one side, making a angle with the radial axis of the branch.
  • the ribs are intended to come into contact with the grid, to scrape this last and, because of their orientation, to drain towards the centers hard elements that do not pass through the grid.
  • the hard elements pass between the separating knife and the grid to find itself in the central hole of it, between it and the drive shaft, said central hole being for this purpose with a diameter much greater than that of said tree.
  • a collection tube is screwed into the support plate and is engaged in the central hole of the grid according to a adjustable recess with possibility of blocking in view to adapt its position relative to the separating knife.
  • the tube is also connected to a drain hose hard elements.
  • the separator knife when a device is fitted to the crusher separator, the separator knife is not intended for swirl in the grid to allow the passage of hard elements, which removes a means of maintaining said knife, while the end of the drive shaft is not no longer required due to the replacement of the bearing by the collection.
  • the transverse maintenance of the end of the shaft is therefore not insured, which results, due to the many constraints to which the separating knife is subjected, and which are increased when the meat is frozen, movements of the separator knife with respect to the grid, which generate premature wear of these.
  • the document FR 2,474,342 proposes a grid also pierced with holes around the edge of the seat where rotates the end of the drive shaft, while the collection tube is held externally against said grid and has holes which, according to the angular orientation of said tube with respect to said grid, are likely to be more or less closed in order to control the size of the elements Hard.
  • this device has another drawback, in effect, adjusting the size selection of hard elements is made downstream of the grid, which causes frequent clogging incidents and requires intervention.
  • the object of the present invention is to propose a device hard element separator for grinder, allowing remedy the various aforementioned drawbacks.
  • the device for separating hard elements for a shredder is of the type comprising, downstream of one or more cutting sets each consisting of a shaped knife of a star with several branches and a grid presenting more or less large openings, a grid intended to stop said hard elements and that is associated with a knife separator designed capable of draining said hard elements towards the center to pass them between said knife and said grid in a collection tube intended to be connected to a discharge pipe, said collection tube being screwed into a support grid or crosspiece according to an adjustable recess with possibility of blocking, by means of a lock nut, with a view to adapting its position relative to said knife separator, and it is essentially characterized in that said collection tube comprises on the one hand an axial housing adapted to receive the end of the knife drive shaft said mill so that it can be held there transversely and journalling there; And on the other hand, peripherally to said axial housing, at least one channel capable of allow the transit of said hard elements to said pipe discharge.
  • the end of the drive shaft is thus maintained and can rotate in the collection tube, while the hard elements can escape through the opening (s) which border the axial housing of said collection tube, which allows, by the possibility of adjusting its sinking, that is to say adapting the distance between its end of the knife, controlling the size of said hard elements.
  • the axial housing of the collection tube intended for receive the end of the drive shaft is lined with a Ring.
  • the drive shaft is often of section other than round, to allow the knives to mesh. Most frequently it has one or more flats, so the ring is shaped adapted to allow the end of the shaft to swivel no play in the collecting tube housing.
  • the collection tube has an axial channel surrounded of a multitude of peripheral channels with axes parallel to said audit axial channel.
  • the axial channel and the peripheral channels extend into the collection tube over a portion of it.
  • the ends of the peripheral channels on the knife side are beveled.
  • a device hard element separator for mill comprises a grid 1 intended to stop the hard elements, associated with a separating knife 2 moved in rotation by a shaft drive 3 having at least one flat.
  • the knife separator 2 comprises in known manner branches 20 provided each on a face of ribs 21 making an angle with the axis radial of the branch 20 which carries them, so as to scrape the grid surface and bring the elements back to the center hard which do not cross the grid 1.
  • the hard elements are, also in known manner, evacuated by the center of grid 1, which is crossed by a tube of collection 4 screwed into a support grid or cross 5 and blocked on the latter by means of a lock nut 40.
  • the collection tube 4 has at its opposite end of the separating knife 2, over a length substantially corresponding to that of the free end 30 of the drive shaft 3, a cylindrical housing 41 axial, bordered at the periphery by channels 42 parallel to the axis of the tube 4.
  • the housing 41 is intended to receive the free end 30 of the drive shaft 3, via a ring 32.
  • the free end 30 of the shaft 3 provided with its ring 43 can thus freely rotate in the housing 41 while being maintained, without preventing the evacuation of the elements hard which pass through the peripheral channels 42, to spread in tube 4 before being discharged into a pipe flexible, not shown, suitable for connection at the other end of tube 4.
  • the separating knife 2 remains in contact with the grid 1, which is maintained by the spider 5.
  • the possibility of move the collection tube 4 relative to the spider 5 makes it possible to vary the space E which separates the knife 2 from the end 45 of the collection tube 4, the variation of this space E allowing adjustment of the size selection of hard elements to evacuate. This adjustment being made upstream of the tube there is no clogging problem, as it is the case with the devices mentioned above.
  • ends of the channels peripherals 42 on the side of the end 45 are bevelled at kind of create 44 larger holes that make it easier evacuation of hard elements.
  • peripheral channels 42 of the embodiment shown are of round section, but they may very well present a different section.
