Definitions

  • Continuous press in particular for the pressing of beet pulps and other products containing juices.
  • the invention relates to a continuous press, intended in particular for pressing beet pulps and other products containing juices, such as green cut fodder, for recovering the juice of these products or else for increasing the dry matter content. of the final product.
  • Beet pulps are made up of the byproduct of the sugar beet pod processing, which allows the sugar to be extracted from them.
  • the residual pulp consists essentially of water and contains only about 6% by weight of dry matter.
  • pulps are usually subjected to a first pressing bringing the dry matter content to about 10% when they are intended to be consumed immediately by animals. If they have to be ensiled for their conservation during the winter, it is necessary to carry out a second pressing giving a dry matter content of about 20 X.
  • a second pressing giving a dry matter content of about 20 X.
  • the pulps must be transported or incorporated into concentrated feed for livestock, their dry matter content must be brought to 85 X, which is usually carried out in two stages, the first consisting in forcing the second pressing to raise the dry matter content up to around 25% on average, the second consisting in thermal dehydration by passage through a dryer heated by fuel combustion. The energy expended for this second stage is particularly expensive.
  • the invention aims to allow a significant reduction in this expense, by increasing the dry matter content of the product to be dehydrated, thanks to a particularly effective pressing of the product.
  • this press comprising a wheel with a rim movable in rotation inside an eccentric ring also movable in rotation and having a diameter greater than that of the wheel, means for clamping the rim of the wheel on the inner surface of the crown, and means for introducing the product to be pressed between the rim of the wheel and the crown upstream of the pressing zone and for extracting the pressed product downstream of this zone, characterized in that the pressing zone is laterally limited by two plates with circular outline which are applied substantially tightly to the sides of the crown and of the rim of the wheel and which have a diameter smaller than that of the wheel so as to leave free, between the wheel and the crown, a zone for introducing the product to be pressed and a zone for extracting the pressed product, these p lacquers being mounted for rotation about an axis parallel to the axis of rotation of the wheel and fixed in position relative to the latter.
  • a press according to the invention makes it possible to obtain pressed products having a dry matter content of the order of 32 to 35% by weight, while the best known presses currently on the market do not allow a value of 26 to be exceeded. %.
  • the internal surface of the crown is formed of a first perforated sheet with relatively fine holes covered, on the side of the rim of the wheel, with a filter cloth and a second perforated sheet at larger holes applying the canvas to the first protest the axial ends of these two sheets having annular edges oriented towards the outside for their fixing in housings formed in hollow in the sides of the crown.
  • This arrangement of a filter cloth between a perforated sheet with large holes and a perforated sheet with much thinner holes prevents the fine holes of the first perforated sheet from being obstructed by the pressed product, while avoiding wear and rapid destruction of the filter cloth which is protected by the second perforated sheet.
  • the rotation shaft of the wheel is supported by rigid levers, one end of which is articulated on the fixed frame of the press around an axis parallel to the axis of rotation of the wheel and the other end of which is articulated by a clamping device such as a jack, at another fixed point of the frame, and in that the crown is supported externally by rotary coils carried by at least one bogie articulated in one fixed point of the press frame around an axis parallel to the axis of rotation of the wheel.
  • FIGS. 1 and 2 represent part of the press according to the invention.
  • this press comprises a wheel 10 with a peripheral rim 12 having a cylindrical outer surface 14 with a wavy profile as shown in the drawings.
  • the wheel 10 rotates, around its axis of rotation not shown in the drawings, inside an eccentric ring which consists essentially of substantially identical coaxial rings 18, which are at equal distance from each other along their common axis and which are rigidly joined together by spacers 20 or the like or which can also be formed in one piece with each other.
  • the rings 18 are substantially flat and have peripheral edges? radially internal and external in triangular shape in cross section, as shown in 22 and 24.
  • the internal surface of the crown is made up in the following way: a first perforated sheet 26, with relatively fine holes, having an undulating shape corresponding to that of the peripheral surface 14 of the rim of the wheel, covers the internal peripheral edges 22 of the rings 18 and has at its ends annular flanges 28 by which it is fixed, for example by welding, in housings formed in the hollow side flanks of the rings 18 of ends.
  • a first perforated sheet 26 On this first perforated sheet 26 is applied directly a te 32 which is folded laterally on the outside so as to cover the annular flanges 28 of the first sheet 26.
  • the end flanges of the second sheet 34 have tabs 36 oriented radially outwardly which are engaged in housings hollowed out in the external sides of the rings 18 and which are fixed in these housings by means of screws 38 in the vicinity of the external periphery of the rings 18.
  • the second sheet 34 is not formed in one piece, but is formed by a plurality of crown sections arranged end to end.
  • the filter cloth 32 can also be formed of pieces fixed directly on the different crown sections constituting the second perforated sheet 34, which makes it possible to quickly replace a defective part of the cloth, without completely changing this cloth.
  • the device for clamping the wheel on the crown thus formed is of the type described in the aforementioned French Patent No. 2,469,273 and comprises coils 40 carried by a bogie 41 connected by a spar and a clamping device such as a jack. (not shown) to a spar 42 supporting the rotation shaft of the wheel 10.
  • the coils 40 are keyed on a hub 44, so as to be integral in rotation with this hub and free in axial translation relative to the latter this.
  • the hub 44 is itself keyed onto a shaft 46 which may be a free shaft or else a drive shaft.
  • the peripheral surfaces of the coils 40 have annular grooves of triangular section corresponding to that of the external peripheral edges of the rings 18.
  • the mounting of the free coils 40 in translation on the hub 44 makes it possible to very precisely position each coil on the corresponding ring 18 and to transmit pressure and drive forces very im load-bearing without deformation of the parts.
  • the product pressing zone which is formed between the line of quasi-tangency between the wheel and the crown and upstream of this line, is closed laterally by annular plates 48 applied and held against the outer flanks of the end rings. 18 of the crown 16.
  • the two annular plates 48 comprise a cylindrical hub 50, oriented towards the inside of the press and ending with an annular flange 52 oriented radially towards the outside. This annular rim 52 determines with the rest of the annular plate 48 an annular groove of rectangular section.
  • the internal peripheral surface of the rim 12 of the wheel 10 also has two annular grooves 54 delimiting, with the lateral flanks of the rim 12, annular flanges 56 oriented radially inwards and which are intended to engage in said grooves annular plates 48 until they abut at the bottom thereof.
  • rollers 58 movable in rotation about an axis parallel to the axis of rotation of the wheel 10, and which bear on the internal cylindrical surface 60 of the hubs 50 of the plates 48 so as to maintain the annular flanges 52 engaged in the annular grooves 54 in the vicinity of the zone of smallest section between the wheel and the crown, that is to say in the vicinity of the zone for pressing the product .
  • the annular plates 48 are easily applied to the outer sides of the rings 18 of the crown 16, due because the folded edges of the perforated sheets are arranged in recesses formed in the hollow in the outer flanks of these rings, so that the surfaces of these outer flanks provided with said perforated sheets remain flat and do not prevent a sealed application of the annular plates 48.
  • annular plates 48 When the wheel 10 is rotated inside the crown 16, the annular plates 48 are driven, by the wheel, in rotation about an axis which is fixed relative to the side members 42 and therefore relative to the axis of rotation of the wheel 10.
  • These radial notches 62 and 64 form teeth intended to mesh respectively with studs 66 fixed by screwing on the outer flanks of the end rings 18 of the crown and with studs or studs 68 passing through the annular grooves 54 of the rim 12 This ensures, by positive gear, a continuous movement of rotation of the annular plates 48.
  • these plates could be driven independently, by a variable speed drive.
  • FIG. 3 illustrates another advantageous characteristic of the invention.
  • the wheel has been represented diagrammatically by a circle 70 of center 0, while the crown is represented by two concentric circles 72 and 74 of center 0.
  • the rotation shaft of the wheel 70 is carried by at least one rigid lever 76, which is for example bent at the axis of rotation 0 of the wheel 70 and one end of which is articulated around an axis parallel to this axis of rotation at a point A of a fixed frame of the machine, while its other ex end is connected to a point P of this fixed frame by median of a jack or other similar device 78 articulated at B on the lever 76 and at P on the frame around axes parallel to the axis of rotation of the wheel.
  • a bogie 80 is articulated at another point E of this fixed frame, around an axis parallel to the axis of rotation of the wheel, and carries at rotation, at its ends 82, two other bogies 84 carrying the coils in rotation 86, for example in the same way as the lips 40 are carried by the bogie 41 in the embodiment of FIGS. 1 and 2.
  • the outer peripheral face 72 of the crown is applied and rests on the coils 86.
  • the wheel 70 is brought more or less close to the inner surface 74 of the crown, the zone of smallest section or zone for pressing the product being located substantially on the horizontal line 88 passing through the axis 0 of rotation of the wheel 70 and the axis of rotation of the upper coil 86, in the case of FIG. 3.
  • this straight line 88 it may be advantageous to modify the orientation of this straight line 88 to tilt it more or less relative to the horizontal, for example depending on the nature of the product to be pressed. For this, it suffices to modify the length of the lever arm 76 between the axis 0 and the point A, which causes the various elements of the press to tilt and move, the points A, E and P which are points of the b3ti remaining fixed.
  • Figure 4 two possible positions of the press according to the invention, the first position, shown in gray, corresponding to that of Figure 3, the second position being shown in stronger lines.
  • the elements of the press in this second position have been designated by the same reference numbers assigned to the index "'". It can be seen that the straight line 88 'defining the maximum pressure zone forms an angle of approximately 15 ° with the right 88.
  • the jack 78 determining the clamping force of the wheel on the crown can be a hydraulic or pneumatic jack, but it can advantageously be a pre-stressed resilient device or an oleopneulatic device (hydraulic jack associated with a gas accumulator) allowing to apply an elastic clamping force of the wheel on the crown.
  • the pressing of the product is then characterized, not by a constant geometry of the pressing zone, but by a constant pressing force of the product.
  • the outer peripheral surface of the rim of the wheel can be formed of a split hoop which is fixed to the rim of the wheel at only one of its ends, the other end being left free so as to avoid differential stresses.
  • the hoop can also be formed of a series of successive sections 90, 91, 92 ... which will each be fixed by only one of their ends on the cylindrical rim 93 of the wheel. The use of this hoop makes it possible to modify on the one hand the external profile of the pressure surface of the wheel and, on the other hand, the external diameter of this pressure surface, without it being necessary to completely change the wheel and proceed to very complicated disassembly.
  • the rotary drive of the various elements of the press can be done for example by means of a first hydraulic motor driving the rotation shaft of the wheel and a second hydraulic motor mounted for example on the shaft of the one of the coils 4C or 86 and driving the crown by means of pinions.
