Definitions

  • the present invention relates to a sealed silo with a suspended envelope, in particular with a suspended metallic envelope.
  • One of the applications of the invention relates to plastic bottle silos, produced in large series in companies for bottling mineral water or other drinks.
  • plastic bottles are produced, upstream of the bottling line, for example of the polyvinyl chloride type, called PVC, by a first chain of extruders intended to produce at high speed by extrusion- blowing plastic containers, in particular PVC, intended to contain the mineral water thus distributed to consumers.
  • PVC polyvinyl chloride type
  • ventilated silos formed of a metal base inclined towards a discharge outlet and of a side and upper surface screened on a framework.
  • the shape of the bottles of square or rectangular section, arranged in bulk in the silo, and their low weight do not facilitate their evacuation movement on the inclined outlet plane.
  • the staff is obliged to push or help certain bottles to descend along the inclined plane and the discharge chute by repeated blows on the rear face of the sheet metal plates. The same is true for bottles stuck at the corners.
  • the base of this type of silo can be dismantled in the form of removable panels which must be dismantled and moved to ensure sufficient cleaning and reassembly.
  • an automatic internal cleaning system can be provided, for example with turnstiles or rotating balls, or any other fluid pressure cleaning assembly, performing the same roles and work.
  • the object of the present invention is to remedy these various drawbacks by proposing a silo with a new structure which is perfectly sealed, light, smooth and resistant, housing a set of insufflation and integrated cleaning.
  • the invention relates to a silo for various bulk products, in particular plastic bottles, characterized in that the metal envelope constituting its walls is formed from sheets of sheets suspended or hung on horizontal and vertical load-bearing profiles constituting an external framework.
  • the invention also relates to the correlative method of constructing a silo or a closed and sealed enclosure with a suspended envelope.
  • the general inventive idea consists in producing a closed storage volume, in particular a sealed sealed silo, in particular for bulk bottles, from an external framework on which sheets of sheet metal, in particular of thin sheet metal, are hung, each of they ensuring with its neighbor a sealing overlap by weld beads on the periphery along its edges including at least one weld of horizontal connection along and in line with or in the vicinity of each bend of attachment of each sheet metal sheet constituting with the lateral extension of a hanging wing.
  • a silo 1 is constituted by an envelope 2 formed of a plurality of sheets such as 3, for example of thin sheet metal, individually suspended from horizontal 4 and vertical 5 bearing profiles of a external framework 6, preferably metallic, taking the general external shape of the body 7 of the silo 1.
  • the body 7 consists of an upper volume 8 of generally semi-parallelepiped shape extended downwards by a pyramidal hopper 9.
  • the framework will then have a general parallelepipedo-pyramidal shape constituted by the perimeter and stepped lateral succession of horizontal 4 and vertical 5 support profiles arranged in several superposed stages 10, 11, 12, 13 and 14.
  • each horizontal perimeter of the hopper 9, or of the upper volume 8 such as respectively 15 and 16 is formed of a succession of sections such as 17 or 18.
  • each oblique amount of the hopper 9 or vertical of upper volume 8 such as 19 and 20 respectively is formed by a succession of inclined 21 or vertical 22 sections.
  • upper longitudinal attachment wings 23 which they have in the upper part, shaped in their upper edge 24. These wings are formed by folding the upper edge 24 to form a transverse support plate 25 with a return 26 for lateral immobilization allowing it to perfectly fit the adjacent bearing profile between two of its consecutive edges and to hang thereon to press on two consecutive faces in order to wedge-hook each sheet sheet in accordance with the invention.
  • the sheet metal sheets 3 are hung directly on the adjacent support profile or on an auxiliary attachment profile 27 attached to it in order to carry out the attachment.
  • the leaves each also have at least one lateral attachment wing such as 28 shaped for example in the same way in a lateral edge 29, each being wedged on a corresponding vertical auxiliary attachment profile such as 30.
  • This double attachment ensures effective wedging of the sheets 3 for vertical and lateral forces.
  • the sheets are of such dimensions that they overlap each other on peripheral overlapping strips such that 31 of minimum width 32 sufficient to achieve sealing and overall cohesion by horizontal weld beads such than 33 and verticals such as 34 (Figure 5). These peripheral bands break down into horizontal 35 and vertical 36 bands.
  • the horizontal and vertical overlaps are carried out opposite the horizontal and vertical load-bearing sections of the framework just in line with the fold of each edge comprising a fastening wing so as to facilitate the execution of the welding and its mechanical strength.
  • the overlaps are also made in the shape change and connection bending zone located at the base of the vertical volume at the connection with the hopper 9.
  • the upper support sections of the hopper 9 and lower of the upper volume 8 are adjacent and the sheets of the first stage of the upper volume have a curved and rounded lower covering edge 37 to ensure continuity in tangent with the inclined hopper plane (Figure 8).
  • the lower part or hopper 9 is of convergent downward shape, conical, pyramidal or other, produced in the same way by hooking and joining together or overlapping identical sheets 3 on the frame profiles, at the using their upper longitudinal wing 23 for attachment.
  • the sheets forming the envelope of the hopper are also wedged or immobilized laterally by additional lateral wings 38.
  • This lower part of general pyramidal shape is produced according to the same general principle of construction and constitution allowing the use of sheets of thin sheet metal.
  • corner sheets 39 and 40 respectively are necessary. They have two perpendicular planes 41 and 42, 43 and 44.
  • each plane has its longitudinal, upper and lateral attachment wing.
  • the silo 1 is closed in the upper part by a cover plane 45 constituted in the same way by sheet sheets 46, hung horizontally on support profiles 47.
  • edge bearing profiles 48 and 49 on which are hung the sheets adjacent to the edge perimeter 50. These sheets have raised attachment wings 51 constituting the extension of the plane of the sheet by a rounded fold 52.
  • the upper end of the sheets of the last side wall stage of the upper volume 8 also has a curved and rounded upper covering edge 53 to ensure tangent continuity with the sheets of the covering plane 45. These edges are welded to ensure the sealing required.
  • the cover-carrying profiles 47 criss-cross the upper space and receive the covering sheets 46 which hook onto the cover plane 45.
  • Crossbars of stiffening are provided such as 54 each comprising a lift pad 55 to which each cover sheet 46 is secured in an additional manner. Because of their horizontal position and their small thickness, these sheets require additional support provided by each lift pad 55.
  • some of the sheet metal sheets have a general trapezoidal or triangular shape.
  • an injection assembly 56 has been provided for blowing a neutral gas or sterile air to ensure ventilation cooling, degassing, aeration and the spraying of water and cleaning and disinfection products, but also to release by jets of compressed air certain bottles which would be stuck or in opposite presentation.
  • This assembly is formed, for example, of a plurality of converging oblique ramps such as 57. These preferably consist of oblique tubes 58 pierced with orifices 59 arranged along the oblique edges at the junction of the inclined planes forming the hopper. Additional reinforcing sections 60 and 61 improve, if necessary, the mechanical rigidity ( Figures 4 and 9).
  • An upper hatch allows the filling of the silo and a lower hatch the exit of the stored products (not shown).
  • a support 62 with four feet such as 63 carries the entire silo.
  • the silo comprises in the lower part a device 64 for collecting and evacuating cleaning water, shown diagrammatically in FIG. 10. This is supported by a suspension arm 65 and consists of a lower cone 66 whose outlet communicates with an exhaust pipe 67.
  • the side wall of the cone is connected to the base of the hopper by a junction formed by a baffle 68 fitted with a seal 69, constituted by a lower wing 70 in engagement with the sheet of sheet metal at the lower end.
  • the invention also relates to the method of constructing a sealed silo.
  • This process consists in constructing on the whole surface of the silo body an external framework in profiles having several horizontal perimeter lines at different levels formed by a succession of profiles. These perimeter lines are connected at intervals by vertical sections.
  • the method then consists in conforming with each upper edge of each sheet of thin sheet metal limited in size, an upper attachment wing on each profile of the frame and on at least one lateral wing. These wings are formed, for example, by a double angle bend with return allowing a hanging with wedging effect.
  • the process finally consists in sealing the silo by welding the lower edges of the sheets of thin sheet metal to the right or in the vicinity of the first fold forming the attachment wing disposed immediately below and ensuring complete sealing by welding the lateral edges superimposed, leaving a minimum overlap strip.
  • the upper cover of the silo is made in the same way as the lower hopper of pyramidal shape.
  • connection zones between the vertical lateral surface and the hopper as well as with the cover plane are made by means of curved overlapping edges.
