Definitions

  • the invention refers to presses of the type for pressing inchoerent humid materials in order to obtain the liquid contained therein as, for instance, it is required in agricolture to press squashed grapes, olive husks and the like.
  • the invention refers to an equipment intended to substitute presses, as screw or hydraulic presses at present in use.
  • Screw presses which are at present the pressing equipments most widely used in agricolture, comprise a cylindrical compartment or "cage" adapted to receive the material to be pressed, having a stationary bottom and an open top through which the cage can be filled.
  • This cage has also an upper wall that can be vertically moved up and down inside the cage by means of a fi-' xed screw and a mobile screw nut fitted thereon.
  • the screw nut is rotated by means of levers in one direction to lower the wall and to compress the material inside the cage and in the opposite direction to lift the wall.
  • Screw presses of this type has many drawbacks, the most serious of which is that the pressing operation of the load cannot be performed continuosly but it must be performed through subsequent steps. Indeed, after loading of the material inside the cage, the upper wall is lowered through a certain length by rotating the screw in order to obtain a certain pressure on the material and, accordingly, a certain quantity of liquid. After this initial pressing it is necessary to wait at least about half an hour before lowering the upper wall by another length to further compress the material and so on.
  • the vertically moving upper wall as well as the mechanical devices associated thereto are completely eliminated and they are substituted by a compartment or cage having stationary walls and containing a bag or "baloon" adapted to be inflated by a fluid supplied by a suitable source outside the compartment.
  • the cage In operation, the cage, that can be opened, is filled with the material to be pressed, while the bag is in the deflated condition and, once the cage is closed again, the bag is inflated through the fluid supplied by the source connected thereto.
  • the increase of the volume occupied by the bag inside the cage causes an identical decrease of the space available for the material and, consequently, the compression of the material betweeen the bag and the cage walls.
  • Another important feature of the invention is that the equipment can make partial use of the presses of the prior art, and more precisely of the cage, that is usually made of circumferentially spaced wood staves, and the support thereof, suitably modified.
  • the equiprent of the invention substantially comprises:
  • Supporting structure 10 is very simple and comprises more legs 11 and a supporting ring 12 fixely attached thereto.
  • Cylindrical compartment 20 has an upper solid dome--shaped wall 21, a cylindrical wall 22 provided with closely spaced openings 23; a solid bottom wall 24, having a similar shape to top wall 24, a ring-shaped basin for the collection of the liquid obtained by the pressing operation, located below cylindrical wall 22; and a connecting pipe 26 for the discharge of the liquid.
  • Bag 30 is of a resistent, resilient, flexible and water-proof material as for instance rubber used in the food trade, and comprises (fig. 2) a mouth 31, a body having a conical portion 32, a cylindrical wall 33 and a bottom wall 34, the bag being arranged with mouth 31 in the lover part and bottom wall 34 in the upper part of cage 20..
  • Mouth 31 is tightly sealed, through a suitable sealing device 35 to the lower end of delivery tube 37, that passes through sealing device 35 and extends axially with respect to cage 20 inside bag 30, having its open end 38 at level with the connection CA between cylindrical wall 22 and upper wall 21.
  • tube 37 may present holes 38A spaced therealong.
  • Tube 45 exemplified as a source of fluid under pressure suited for use in the equipment of the invention, can be a flexible hose having one end connected to a tap of a water network for drinking or irrigation purposes (having a minimum pressure of approximately 2 kg/cm 2 ) and the other end tightly connected to lower end 39 of tube 37 that protrudes below sealing device 35.
  • a three-way limiting valve LV is connected for security reasons to limit the pressure inside bag 30 at a preselected maximum value in order to avoid the danger of excessive inflation of the bag and consequent "bursting" of the cage.
  • cage 20 must be adequately resistent, or rendered still more resistent in case of compartments of already existing presses, particularly in correspondence with connection area CA between the lateral wall and the upper and bottom walls, since the pressure of pressing is uniformly distributed against the cage walls.
  • the equipment is integrated by a pump DP and it is sufficient to arrange for a water tank, as exemplified by well WP, to draw water therefrom through pipe C1 and to supply this water to bag 30, (not shown in this figure, as it is inside cage 20) through limitation valve LV, of the three-way type, and hose 45; duct C2 returning the water to well WL in case of excessive pres sure.
  • a water tank as exemplified by well WP
  • Naturally pump DP must have such a power to supply water with a sufficient pressure as indicated.
  • any equipments to press humid incoherent materials comprising a solid compartment of whatever s-hape, having at least one wall provided with closely spaced openings, suited to contain humid incoherent material to be pressed and a bag, also said bag of any suitable shape, arranged in any way inside the compartment and suitably connected with a source outside the compartment, but able to deliver any fluid under pressure as to inflate the bag insi - de the compartment and progressively to reduce the space available for the material to be pressed, which material therefore will be compressed and pressed, so that the liquid obtained in this way, can be collected outside the compartment.
