Definitions

  • the present invention relates to a cover unit for covering a substantially circular holder for holding one or more fluids and/or solids.
  • the invention also relates to a method for manufacturing such a cover unit.
  • holder For the purpose of storing fluids (liquids and/or gases) or solids (such as for instance bulk goods) use is made of a wide variety of holders, such as liquid tanks or liquid containers, (manure) silos, reservoirs and storage systems generally.
  • the embodiment of the holder may depend on the specific application, such as for instance manure storage, water treatment, fire prevention (sprinkler installation) and fermentation, on the quantity of fluid or solid for which the holder must provide space, on possible legal requirements laid down for the holder, etc.
  • the holders are often open on their top and can be covered so as to protect the internal space of the holder from outside influences.
  • the cover may also have the function of protecting the outside environment from the release of unpleasant odours or the occurrence of other emissions adversely affecting the environment.
  • a first example of a cover construction is a floating deck wherein a floating cover layer is arranged on the liquid surface in the holder.
  • a floating deck does however have a number of drawbacks. Firstly, it is relatively difficult to mix the liquid in the holder because of adhesion of the liquid, for instance manure, to the floating deck itself.
  • a further drawback is that inspection or an operation under the floating deck is not possible, or only with difficulty.
  • gases are generated under the floating deck, for instance when the holder is used for the storage of liquid manure from which biogas is released, these accumulate against the underside of the cover layer. These gases cannot be readily recovered in such a construction and use of the biogas, for instance to generate energy, is hereby made more difficult.
  • span cover This is a conical tent construction consisting of an upright which is disposed in the middle of the holder and from which a cloth is suspended. The cloth is also fastened to the wall of the holder. Many tensioning straps run under the cloth from the middle to the wall. It is important in this construction that the wall can take up the forces from the tensioned cover toward the inside. For a relatively strong, for instance concrete holder wall, this need not be a problem. In the case of less strong holder walls, the transverse forces exerted by the cover on the wall are however too great, whereby damage to the wall can result.
  • a further cover construction is a further development of the span cover.
  • a wooden roof construction is herein arranged on an upright disposed in the middle of the holder.
  • a cloth is tensioned over the wooden roof construction.
  • a drawback of this type of cover is that only a limited span (a maximum of about 20 metres) is possible, that the span, as in the case of the span cover, is not column-free, and that the cover is relatively costly.
  • segment cover consisting of a number of wooden trusses with roof covering on the top side of the trusses.
  • the cover is per se form-retaining and a column need not be placed in the middle of the cover.
  • segment cap has a relatively high weight, is extremely expensive owing to the use of the wooden truss construction and moreover provides only a limited maximum span (diameter less than 16 metres).
  • covers consisting of a frame against which a large number of form-retaining panels are attached. This cover is also very expensive and generally involves a relatively high weight. Nor therefore is this type of cover suitable, or at least less so, for application on holder constructions with relatively little bending stiffness.
  • a cover unit for covering a substantially circular holder for holding one or more fluids and/or solids, wherein the cover unit comprises:
  • Such a cover unit has a number of advantages. By erecting the support construction of the cover unit from a number of rod-like structural members the weight can remain relatively low. The separate structural members and the cover layer are moreover east to transport.
  • the tensioning means engage on the cover layer and thereby on the frame itself. No tensioning forces are exerted on the holder itself. In combination with the dome form of the frame, this ensures that the cover unit applies only downward forces on the holder wall and transverse forces remain absent. Because no transverse forces are exerted on the wall, the cover unit can also be applied in the case of less strong or rigid wall constructions.
  • the cover unit can furthermore be realized with simple means, wherein all operations for constructing the cover unit and arranging thereof on the holder can basically be carried out at ground level. It has been found in practice that the cover unit can be manufactured and arranged quickly. A cover unit of average dimensions can for instance be assembled in two to three days by three to four people.
  • the outer ends of the rod-like structural members preferably meet in different nodes substantially in the plane of the dome form.
  • the dome form can then be realized quickly and easily by supplying the structural members separately and coupling them together onsite in the intended nodes.
  • the cover unit for covering the holder can be placed on an array of supports ordered in the form of a circle. These supports can be formed by a number of standing support elements extending in the form of a circle and placed inside the holder or outside thereof.
  • the top side of the holder wall can however be applied equally well in many cases for this purpose (wherein the upper edge of the holder is seen as a number of supports placed side by side).
  • the cover unit is arranged by placing the folded-back edge portion of the cover layer on said supports.
  • the diameter of the dome form is greater than a diameter of the holder and, in the position of use, the folded-back edge portion of the cover layer rests on the top side of the holder wall. A good sealing between the cover unit and the holder wall is hereby achieved.
  • the peripheral edge is situated lower in the position of use than the top side of the holder wall, so that the cover layer remains pressed on the holder wall as a result of the bias by the tensioning means.
  • the frame is embodied is wood.
  • the material in the holder contains (aggressive) substances which can adversely affect the frame
  • hardwood or protected metal such as stainless steel or aluminium
  • the frame is constructed from aluminium, which results in a very light construction.
  • the design has a low own weight through the use of a flexible cover layer.
  • the cover layer is preferably manufactured from reinforced PVC cloth.
  • the low weight is particularly important in the case of holder walls with very little bending stiffness, as already set forth above.
  • the cover unit comprises half-trusses which extend radially outward from the centre of the dome form and which are formed in each case from at least two mutually coupled rod-like structural members. A greater or smaller number of structural members are successively placed depending on the intended dimensions of the cover unit.
  • the construction of the half-trusses of a frame for a large span hereby corresponds to the construction of a frame for a relatively small span. This already results per se in a standardization of the applied structural members and of the method of manufacturing the frame.
  • the cover unit comprises a number of connecting elements between the half-trusses, wherein a connecting element extends between the end of a first structural member of a first half-truss and the end of a first structural member of a second half-truss.
  • the connecting elements hereby form "rings" in the frame.
  • pull rod elements In those rings of the frame situated in the vicinity of the part of the frame which must rest on the supports there are however provided pull rod elements for the purpose of forming a connection under strain of tension between the half-trusses.
  • the pull rod elements form the edge of the dome, though this is not essential. If the frame has dimensions such that an overhang is formed, the pull rod elements can be provided in a "ring" further to the inside.
  • the pull rod elements of the frame take a hollow form and tensioning means, preferably in the form of one or more tensioning cables 47, are arranged through pull rod elements for taking up the tensile forces in the pull rod elements. Because the tensioning means in this embodiment take up the tensile forces which occur, the pull rod elements can also be given a structurally lighter form. It is even possible to place the pull rod elements, in addition to the other elements of the frame, only under strain of pressure, which means that securing of the elements can be dispensed with.
  • the tensioning means can then be arranged on the outside of the ring of pull elements.
  • Said pull rod elements are preferably manufactured from steel, which does after all have a high maximum tensile load. Since the maximum tensile load is not an important factor in the connecting elements, other materials can also be used for these elements, such as plastic, aluminium or wood.
  • cables are arranged, should this be necessary, between the structural members. These cables are arranged in order to mutually connect the structural members and thus decrease the danger of the structural members buckling and/or limit the sag of the flexible cover layer.
  • the cover unit therefore comprises a gas membrane fixed to the frame for collecting gas therewith. Owing to the fixed spherical shape of the frame and the absence of an intermediate support it is possible to store a maximal quantity of gas.
  • the storage capacity of the gas is after all not limited by the presence of intermediate supports and the spherical space under the dome furthermore has a larger capacity than the conical form of the cover applied in many cases. This advantage is all the greater compared to the situation in which a flat cover, for instance a concrete roof, is applied.
  • the cover unit comprises a suspension unit for suspending the gas membrane from the frame, wherein the suspension unit is embodied for the purpose of limiting a lowest position of the gas membrane to a preadjusted level. In the lowest position the cover layer will in other words not be able to make any contact with the liquid surface. In the case for instance manure is arranged in the holder, there would otherwise be the danger of manure caking onto the membrane.
  • the gas membrane is preferably arranged on a suspension unit provided in the central area of the dome.
  • the membrane is preferably connected to the tensioning means, for instance the tensioning cable or the tube in which the tensioning cable is received. From this connection the gas membrane runs outward in the direction of the holder wall.
  • the gas membrane then runs over the wall to the outside or extends downward as an apron on the inside of the wall. In the case the gas membrane hangs downward as an apron on the inside of a wall, the length of the gas membrane is made such that a natural water seal is created. As a result, the gas in the holder cannot escape.
  • weights can be attached to the underside of the apron, preferably by incorporating these in the hem of the membrane, in order to ensure that the apron hangs in the liquid at all times. Owing to the development of the gas pressure, the apron will adjust to the greater or lesser degree of non-roundness of the holder.
  • a cover unit preferably the above described cover unit, wherein the method comprises the steps of:
  • the cover unit can be manufactured and placed on the holder in quick and simple manner.
  • Figure 1 shows a manure silo 1 of circular cross-section.
  • the walls of the manure silo have a flat top side in the shown embodiment.
  • the material from which the silo is constructed can take many forms.
  • silos are known which are manufactured from material with little bending stiffness, such as corrugated steel sheets.
  • the walls are sometimes also constructed from plastic.
  • This cover exerts only downward forces on the silo wall (at least when external forces, for instance as a result of wind load, are not taken into account, which external forces could cause a general shearing force in the plane of the top side of the holder) and moreover has relatively low weight.
  • the construction of the cover will be described hereinbelow.
  • FIGS 2A and 2B show a cross-section in more detail of the construction of cover 2.
  • Silo 1 is constructed from a bottom 3 and a standing wall 4.
  • Cover 2 consists of a number of rod-like structural members which meet in the middle in a central connecting member 22, which member is also referred to as the king post.
  • the rod-like structural members form a dome-shaped frame 5 over which is tensioned a cover layer, for instance a PVC cloth of about 1 mm thickness.
  • a cover layer for instance a PVC cloth of about 1 mm thickness.
  • the cloth will be arranged tightly round the frame and thereby follow the shape of the frame. It will not be a perfect spherical shape that is then discernible from the outside but rather a number of faces at different angles and tensioned by the different structural members.
  • Tensioning takes place as follows. Cloth 6 is first arranged over frame 5. The excess of cloth 6 is folded back round edge elements 30 of frame 5 and subsequently tensioned on the inside using a tensioning cable 7. As a consequence of this tension, covering cloth 6 is pulled taut over the frame.
  • FIG. 3 shows that covering cloth 6 is folded back round edge element 30 of frame 5.
  • the folded-back edge portion 6' of cloth 6 is arranged on a tensioning cable 7 enclosed by a protective tube 25.
  • Edge portion 6' is herein fastened by guiding the tensioning cable 7 through a hem 26 provided in the outer end of edge portion 6'. Once the tensioning cable 7 has been arranged in the peripheral hem 26 of edge portion 6' of cloth 6, it is tightened at one or more positions so that cloth 6 is pulled taut over frame 5.
  • a condensation collecting layer 27 is further provided to collect possible condensed water inside the silo.
  • the arranging of a condensation collecting layer is important if it is undesirable for this condensation, via the slope of the roof, to accumulate above the wall or drip downward along the surface on the inside or outside of the wall. This is particularly undesirable when this condensation may be aggressive to the wall. It is the intention that the moisture drops downward before reaching the wall. This is possible in at least two ways, by welding a strip against the underside of the cloth within the radius of the wall, or by folding back a strip of cloth inward from the edge tube over the tensioning unit.
  • FIG. 5 shows in cross-section a preferred embodiment of such a support 31.
  • the support is fixed to frame 5 and has a flat underside 32.
  • the flat underside 32 of the support is placed on the flat upper side of silo wall 4.
  • anchoring element 33 is fastened to the silo wall using for instance screws 34.
  • the flat underside 32 of support 31 has a relatively large width b. This has the function of being able to compensate for possible non-roundness of silo 1. Support 31 can therefore be applied within relatively large margins of non-roundness of the holder, which is advantageous in practice, and then particularly when a cover is arranged on an already existing holder. In existing silos the silo wall 4 can often no longer be described as wholly round in top elevation. Cover 2 does not however have to be made specially to size, as long as the non-roundness of the silo remains within the margin defined by the width b of the underside 32 of support 31. The dimension b is determined by the maximum tolerance associated with the holder in question.
  • FIG. 4 An advantageous embodiment of the dome construction is shown in the view of figure 4 and the related cross-sections of figures 6-9.
  • Figure 4 shows with full lines a framework with two "rings” for a dome of a determined diameter.
  • the extension in the case of a framework with three “rings” for a dome of a larger diameter is indicated here with broken lines.
  • the dome is constructed from the following main components:
  • distributing rods (E4,E5 respectively E9, E10, E11, E12) which run from the nodes on the first intermediate ring to the intermediate nodes on the second ring, and from the second ring to the nodes on the following ring.
  • An optional third intermediate ring (not shown in figure 4) or pull strap consists of three times as many rod elements as the number of half-trusses applied.
  • the optional fourth intermediate ring or pull strap consists of the same number of rod elements as the third intermediate ring.
  • the rod elements - not being elements in the pull strap - are characterized by being mainly under strain of pressure and bending.
  • the building sequence for constructing a two-ring dome is as follows. Elements R6 and R7 are first fixed to each other. Elements E3,E4 and E5 are then attached, whereafter it is the turn of elements E2 to be attached. Elements E1 are the last to be attached.
  • a suitable dome construction can hereby be built in rapid and efficient manner and with a minimum of manpower.
  • FIG. 6 shows a detail of the connection of edge elements R6 and R7 to structural member E3.
  • the edge elements are embodied here as round tubes, the outer ends 34,35 thereof being flattened.
  • the flattened ends of the tubes are coupled to each other with a strip 36, for instance by fastening the strip to the ends using a number of bolt connections.
  • figure 7 shows a detail view of the connection of edge elements R6 and R7 to two structural members E4 and E5, which connection corresponds to that of edge elements R14 and R15 to structural members E9,E10 or E11,E12.
  • the outer ends 34 and 35 are here coupled to each other by a strip 37.
  • Figure 8 shows a detail view of king post 22.
  • the king post is arranged in the middle of the dome and functions as connecting element for all rod elements E1.
  • a further function of the king post is to provide an optional opening in the middle of cover layer 6, which creates the possibility of gaining access to the interior of the silo.
  • Figure 8 shows an embodiment in which the structural members E1 all meet at one point.
  • Figure 9 shows an alternative embodiment in which king post 22 fulfils the same function of receiving structural members E1, wherein an opening 29 is provided in the middle of king post 22.
  • Covering cloth 6 is herein arranged on a flange 48, wherein an opening is provided in the middle which corresponds to opening 29 in the king post. This provides the option of gaining access to the interior of the silo from above.
  • Figure 10 shows an embodiment in which the structural members are formed by round tubes 43, 44 and 45. These are mutually connected using a connecting piece 38 which is made from a tube 41 with a diameter smaller than that of tube 43 and 44 and a tube 40 with a diameter smaller than tube 45. Tubes 40 and 41 are mutually connected using a strip 39. A portion 42 of tube 41 is pushed into tube 43. In similar manner a portion of tube 41 is pushed into tube 44. Structural members 43-45 can be attached to each other in simple and rapid manner using connecting piece 38. When structural members 43-45 are furthermore only under strain of pressure, a separate securing can be dispensed with. Also in the case that structural members 43-44 are pull rods, it is possible to apply the shown connecting piece if there is arranged through the interior of structural members 43-44 a tensioning cable which can take up the tensile forces which occur.
  • a further aspect of the invention relates to the structural possibility of collecting a fluid such as manure gas G above another fluid and/or solid such as liquid manure V.
  • a cord 21 is fastened to king post 22, on which cord there is arranged a gastight membrane 20.
  • This membrane hangs downward from cord 21 and is fastened along the wall to tensioning cable 7 or at least the tube 25 arranged therearound.
  • Gas membrane 20 runs herefrom in the direction of silo wall 4. Depending on the type of silo wall and the preference of the installer, gas membrane 20 then runs first over the top side of wall 4 to the outside or gas membrane 20 runs downward as apron 20' on the inner side of silo wall 4.
  • a number of weights 23 are furthermore arranged on the underside of apron 20' in order to ensure that the apron is always pulled tautly downward, and the underside thereof is at all times below the lowest liquid level and will always extend below the lowest possible liquid level in the silo.
  • Figure 2A shows the situation in which relatively little liquid V and little gas G is present in the silo.
  • cloth 20 will bulge out.
  • the cloth will here ultimately follow the form of the underside of the dome, so that optimum use can be made of the storage capacity under the dome shape.
  • the length of cord 21 is chosen such that the gastight cloth 20 cannot contact the surface of the liquid V in any way whatever. This prevents possible caking of liquid (manure) on cloth 20, in which case the quality of the cloth can be adversely affected.
  • Figure 2A also shows that in a further preferred embodiment an insulating layer 46 is arranged against the underside of the frame.
  • an insulating layer 46 is arranged against the underside of the frame.
  • the covering cloth 6 is folded back round a rotatable edge element 49 of frame 5.
  • the folded-back edge portion 6' of cloth 6 is arranged on a tensioning cable 7 enclosed by a protective tube 25.
  • tensioning cable 7 Once tensioning cable 7 has been arranged in the peripheral hem 26 of edge portion 6', it is tightened at one or more locations so that cloth 6 is pulled taut over frame 5.
  • cloth 6 is secured mechanically to edge element 49 by providing the edge element with one or more protrusions 50 which can be guided into corresponding openings in cloth 6.
  • edge element 49 This creates the possibility during tightening, or later, of rotating edge element 49 further (in direction P) or less far on its axis, so that cloth 6 (re)gains tension.
  • the cloth can also be tensioned by fixing the membrane in the lengthwise direction of the edge element and by then rotating the edge element on its longitudinal axis.
  • Edge element 49 is then fixed at the end of the rod at the position of the connection to other rods, so that the cloth retains the desired tension.
