Description

Bearing block and production method

Technical Field

The present invention relates to a support block for storing a tank body for cryogenic liquids (in particular liquefied gas, LNG, LPG, ethylene, etc.) and a method for producing the same, the support block being formed of dense laminated wood, the dense laminated wood being formed of veneers, the veneers being impregnated with synthetic resin and being stacked, the stack being subsequently densified at high temperature to form dense laminated wood, the support block forming a support side facing the tank body for connection with the tank body. The invention further relates to a tank with a support block, to a ship with a support block and to the use of an aerogel for producing a support block.

Background

Dense laminated wood is well known and used in a variety of technical fields. In particular, due to its superior electrical performance, it is commonly used as an electrical and thermal insulation material in oil-filled power transformers, rotors of turbine generators, and similar locations where heavy objects need to be supported.

Dense laminated wood, as defined and described by DIN EN 61061, is usually produced from veneers, which are usually produced by slicing or rotary cutting of the trunk. Thus, there is a distinction between flat cut veneers and rotary cut veneers. The veneers are then impregnated (in particular soaked or coated) with a synthetic resin and stacked, followed by densification or compression of the stack at elevated temperature to form a densified laminated wood, the term "elevated temperature" especially denoting a temperature range of from 100 ℃ to 300 ℃, preferably in the range of 150 ℃.

All technical specifications mentioned in the present patent application refer to versions applicable at the decisive date of the priority date of the patent application.

Furthermore, the use of dense laminated wood to form support blocks for storage of tanks for cryogenic liquids is known. The dense laminated wood is impregnated with a synthetic resin so that a sufficiently stable support block can be formed from the dense laminated wood. The tank is usually supported by several blocks or series of supports forming a fixed or floating support for the tank. Dense laminated wood is well suited for forming such a support block because it has good thermal insulation properties. On the support side of the support block, i.e. the side facing the respective tank, the temperature of the support side may be-160 ℃ or lower, for example, when a tank made of metal is filled with a cryogenic liquid. Meanwhile, the temperature away from the lower side of the can body or the supporting lower side of the supporting block may be, for example, -30 ℃ to 0 ℃ or more. The height of the bearing block is therefore dimensioned such that the desired insulating effect is achieved. Particularly when the tank is installed in a vessel, any components adjacent to the support block must not be cooled below 0 ℃, either because this may lead to brittle fracture of the components or because the components must not be cooled below a certain allowable temperature. By cooling steel, in particular steel for ships, below 0 ℃, the elastic limit is greatly changed.

A similar arrangement of such a bearing block is known, for example, from EP 1945498B 1. Experience has shown, however, that the bearing block may exhibit undesirable cracks. This may occur when the bearing block is cooled down rapidly on the bearing side due to the filling of the can body. Due to the good heat insulation effect of the dense laminated wood, the cooling process from the bearing side towards the interior of the bearing block progresses only very slowly, so that large temperature differences in the bearing block may occur in the region of the bearing side, so that tensions may occur which form cracks in the bearing side. Possible cracks can lead to a reduction in the strength of the respective bearing block or even to destruction. In addition, ice formed on the cracks may also reduce the insulation effect.

Disclosure of Invention

It is therefore an object of the present invention to provide a support block for storing a tank for cryogenic liquids or a tank with a support block, a vessel with a tank and a method for producing a support block, which support block is improved in terms of service life.

This object is achieved by a support block having the features of claim 1, a tank having the features of claim 20, a vessel having the features of claim 21, a method having the features of claim 22 and the use of an aerogel having the features of claim 23.

The support block for a tank body for storing cryogenic liquids (particularly liquefied gas, LNG, LPG, ethylene, etc.) in a ship according to the present invention is formed of dense laminated wood formed of veneers impregnated with synthetic resin and stacked, the stack being subsequently densified at high temperature to form dense laminated wood, the support block forming a support side facing the tank body so as to be connected to the tank body, a gap being formed in the support side of the dense laminated wood, the gap extending substantially orthogonal to the support side, the gap being filled with aerogel.

It has been found that the strength properties of the bearing block according to the invention are not significantly degraded due to the formation and filling of the aerogel gaps in the bearing side, since the pressure is essentially applied to the bearing side. Furthermore, the gap prevents undesirable cracks from forming in the region of the bearing side. Since the gap extends through the bearing block in the region of the bearing side, the bearing side of the bearing block is divided into at least two surface regions. The aerogel arranged in the interspace has particularly good thermal insulation properties and is hydrophobic. At the same time, the aerogel is flexible, and can counteract tension due to temperature expansion in the interstitial regions, or compensate for shrinkage in the dense laminated wood. Furthermore, the good insulating properties of the aerogel allow the gap to be formed relatively narrow, so that the strength of the support block is not substantially affected, and the dense laminated wood remains thermally separated on either side of the gap. Meanwhile, filling the gap with the aerogel effectively prevents dirt, water, and the like from penetrating into the gap. Overall, this can prevent crack formation due to thermal stresses and thus extend the working life of the bearing block.

The gap may be formed to extend from a lateral surface of the bearing block adjacent the bearing side to an opposite lateral surface of the bearing block adjacent the bearing side. Thus, the gap may extend continuously from the lateral surface to the opposite lateral surface. In principle, however, the gap can also be formed only in a part of the bearing side.

The gap may penetrate through a portion of the bearing block, preferably up to 20%, 35%, 50% or 70% of the height of the bearing block. This means that in this case the gap does not completely divide the bearing block, but only partially. The height of the bearing block refers to the distance from the bearing side to the lower side of the bearing block. Then, a gap is formed in the support block from the support side toward the lower side. Depending on the desired temperature difference between the bearing side and the underside, a height-dependent gap can be formed accordingly. Therefore, it is possible to ensure that even in a deep region in the support block, the formation of cracks due to tension can be prevented.

Advantageously, the bottom of the gap may be formed with a radius. The radius prevents a notch effect at the bottom of the gap. For example, the radius may correspond to half the width of the gap.

Further, the radius may be formed by a hole having a diameter greater than the width of the gap. This type of hole safely avoids the notch effect at the bottom of the gap.

The gap may be formed to extend continuously over the circumference of the bearing block. Thus, the gap may extend over the entire circumference of the bearing block: starting from the support side, over the adjacent lateral surface of the support block, over the underside, towards the opposite lateral surface of the adjacent lateral surface, and back to the support side. In this case, the gap does not penetrate completely through the bearing block. In this way, cracks can be prevented from forming on the outer surface of the bearing block due to thermal stresses. For example, the gap may be formed by a circumferential kerf in the support block.

The support block may be formed by a first block and a second block, which are firmly connectable to each other by means of an adhesive material. In principle, the bearing block can be formed as a single piece. By forming the bearing block from the first block and the second block and then gluing the first block and the second block together, a larger bearing block can be produced particularly easily. The support blocks may also be formed by a number of blocks greater than 2, for example 4 blocks or 5 blocks. At the same time, an adhesive bond can be applied such that the aerogel is disposed between the first and second pieces. The aerogel can thus be arranged particularly easily in the gap. The blocks may be formed as block halves or may have different sizes.

The gap may extend in a common plane with the bond line or orthogonally with respect to the bond line of the block. For example, the gap may be formed particularly easily by forming a recess in the first and/or second block adjacent to the adhesive seam or in an extension of the block. The aerogel can be inserted into the recess and then fill the gap in the bond line after the first and second pieces are glued together. Alternatively, the adhesive seam may extend orthogonally with respect to the gap, for example on the bottom of the gap, so that the first and second pieces are connected to each other via the third piece. Synthetic resin or glue may be used as the binder.

The support block may have at least one connecting means made of dense laminated wood and connecting the first block with the second block, the connecting means being capable of spanning the gap. For example, the connecting means may be a protrusion formed in the bearing block and then forming a gap. Thus, the connecting means spans the gap and connects the first and second blocks of the support block to each other. Alternatively, the connecting means may also be a plate made of dense laminated wood, which is arranged on or glued to the first and second blocks.

The connecting means may be an extension formed on or inserted into the first block and/or the second block. The extension may be formed by one or both of the blocks and may span the gap. Alternatively, a recess into which the extension is inserted may be formed in one or both of the blocks by milling, for example. The extension may be glued to the block by means of synthetic resin.

The support block may have a plurality of connecting means, which are bolts or rods. For example, four connecting means symmetrical with respect to each other may be provided between the bearing blocks. The connecting means may be formed in the form of a bolt or a rod and span the gap. The connecting means can generally have any cross section, circular or square cross sections being particularly simple to produce. If the connecting means is a bolt, the first block and the second block may each have a hole formed by milling, into which the connecting means is inserted and glued by means of synthetic resin. In addition to the connecting means, it is also possible to provide round or angular projections or plates which surround the connecting means and determine the width of the gap. Such a plate may be formed independently of the connecting means or may be formed on said connecting means in the manner of a collar.

The ratio of the width of the gap to the thickness of the block may be 1: 30 to 1: 50, the thickness of the blocks are preferably of equal size. The gap is relatively narrow compared to the thickness of the block, so that the strength of the support block is hardly affected by the gap. For example, the width of the gap may be determined by the connecting means. The width of the gap can also be formed in a defined manner by a plate or a projection inserted into the gap. If the thickness of the blocks are of equal size, the blocks can be inexpensively mass produced. If the bearing block is formed by two such blocks, the gap always extends through the center of the bearing block. In general, some blocks may also be arranged in a row in the following way: forming a gap which extends through the bearing blocks at always the same distance relative to each other.

The gap may be completely filled with aerogel. Thus, the bearing block may form a continuous, closed surface, including in the region of the gap. Thus, dirt or water cannot penetrate into the gap.

The veneer may be maple, birch or beech, preferably beech (european beech). For example, beech has advantageous mechanical and electrical properties compared to spruce or pine due to its natural homogeneity and ideal cell structure. Spruce or pine, even carpinus turpini in europe, may also be used.

The dense laminated wood may be completely impregnated with a synthetic resin, which is a phenol resin. The synthetic resin may be applied to the veneer before the veneer is densified or compressed. The viscosity of the synthetic resin may allow the synthetic resin to substantially fully impregnate the veneer such that the densified laminated wood may be fully impregnated with the synthetic resin. For example, complete impregnation can be achieved by vacuum impregnation. In particular, phenol resin or phenol formaldehyde resin glues can be used, whereby the dense laminated wood or veneer can be bonded or glued together with the desired effect of preventing delamination.

Advantageously, the dense laminated wood may have a weight percentage of phenol formaldehyde resin of at least 25%. Phenol formaldehyde resins result from the hardening of phenol resins in dense laminated wood. With this ratio of phenol formaldehyde resin, a dense laminated wood can be formed having sufficient strength characteristics to be used as a support block. The absorption of water by the dense laminated wood can be substantially excluded.

The surface of the support block may be coated with a synthetic resin. Preferably, the entire support block or a surface thereof may be coated with a synthetic resin. In this case, since the surface is coated with synthetic resin, water or liquid can be prevented from entering the dense laminated wood, and thus the support block is almost hydrophobic. The surface of the densely laminated wood and/or veneer can be worked, in particular polished and/or planed. Thus, in addition to the most precise tolerances, a particularly desirable and rapid absorption of the synthetic resin can be ensured when using a dense laminated wood as material for the bearing block. The surface of the bearing block may also be uncoated if the bearing block is completely impregnated with synthetic resin.

The single sheets may be arranged to have a grain direction parallel, staggered or tangential to the stack, the grain direction being extendable laterally, orthogonally or preferably parallel with respect to the gap. Tangential grain direction is advantageous in particular for dense laminated wood with block-like geometry, since in particular the required bending stiffness can be optimized thereby. The selection of a particular grain direction or layer direction also affects the mechanical and thermal insulation properties of the densified laminated wood. For example, the thermal expansion of a dense laminated wood parallel to the lamination or grain direction is much smaller than the thermal expansion of a dense laminated wood transverse to the lamination or grain direction. Thus, the lamination direction or the grain direction preferably extends orthogonal or parallel to the support side. The grain direction may extend vertically and parallel with respect to the gap, or vertically and orthogonally with respect to the gap. Thus, these properties of the densified laminated wood can be customized depending on the construction environment or requirements by selecting a particular grain direction.

Further, the density of the dense laminated wood may be 0.7g/cm ³ To 0.9g/cm ³ 、0.9g/cm ³ To 1.1g/cm ³ 、1.2g/cm ³ To 1.35g/cm ³ Or 1.35g/cm ³ To 1.4g/cm ³ . A particular density can be achieved by selecting a particular level of compression for the densified laminated wood. The level of compression also affects the mechanical and thermal insulation properties of the dense laminated wood. Preferably, the density may be 1.4g/cm ³ 。

The bearing block arrangement may be formed by at least two bearing blocks, which are firmly connectable to each other by means of a synthetic resin. A support block arrangement may be realized such that the arrangement is formed by a plurality of support blocks glued to each other, forming a bonding gap. The adhesion gap may be filled with synthetic resin, so that dirt or water is prevented from penetrating into the adhesion gap, and the support blocks are firmly mechanically connected to each other.

The can body according to the invention comprises at least one bearing block according to the invention.

The can may be approximately cylindrical or approximately spherical (type A, B or C). The can body may have a number of different support blocks that enable storage or positioning of the can body. Furthermore, the can may be provided with a supplementary insulating material, such as polyurethane foam. The tank may be a fuel tank, a storage tank or a transport tank.

The vessel according to the invention has at least one tank according to the invention. The vessel may also have a plurality of tanks, each having a support block. The support block or blocks may be fastened to the tank and/or the building elements of the vessel by casting resin. The casting resin may be used in the form of a filling material for connecting the support blocks to each other, to the tank and/or to the building elements of the vessel, the deck of the vessel and/or the floor or side walls of the hull in the hold of the vessel. Depending on the shape of the support block, it can be a fixed support or a floating support. It is also possible to disperse some of the support blocks in a semi-circle around the tank body or as separate large-sized support blocks under the tank body.

Detailed Description

By way of example, fig. 1 shows a cylindrical can body 10 with bearing blocks 11 and 12. The support 11 is substantially semicircular and is arranged on the can body 10 coaxially to the longitudinal axis 13 of the can body 10. The bearing block 11 forms a fixed support 14 for preventing the can body 10 from moving towards the longitudinal axis 13 or the can body 10 from rotating relative to the longitudinal axis 13. The support blocks 12 prevent the can body 10 from floating transversely to the longitudinal axis 13. The tank 10 is for receiving a cryogenic liquid, such as liquefied gas or the like.

Fig. 2 shows a support block 15 formed from impregnated densified laminated wood. The dense laminated wood is formed of veneers (not shown) which are impregnated with a synthetic resin and stacked, and the stack is subsequently densified at an elevated temperature to form the dense laminated wood. For example, the support block 15 is a support block used with an a-type can body. The support block 15 forms a base 16 for resting on a surface. A can (not shown) may be placed on the support side 17 of the support block 15. In the support side 17, gaps 18 are formed in the densely laminated wood. The gap 18 extends through the bearing block 15 orthogonally to the bearing side 17. The gaps 18 are completely filled with aerogel 19. In particular, the gap 18 extends from a lateral surface 20 adjacent to the support side 17 to an opposite lateral surface 21 of the support block 15 adjacent to the support side 17.

The combined views of fig. 3 to 5 show a further bearing block 22, which bearing block 22 can form a fixed support for a tank (not shown). The support block 22 is formed by a first block 23 and a second block 24, the

blocks

23 and 24 being firmly connectable to each other by means of an adhesive material (not shown). The first piece 23 and the second piece 24 are made of densely laminated wood and glued to each other along a glue seam 25. The bearing block 22 forms a bearing side 26 for supporting a can body (not shown), the bearing side 26 having a groove 27 formed therein, the groove 27 being adapted to receive a rib or center plate (not shown) provided on the outside of the can body. Furthermore, a gap 28 is formed on the support side 26, the gap 28 being substantially aligned with the adhesive seam 25 and extending orthogonally to the support side 26 relative to the support side 26. On the bottom 29 of the gap 28, a hole 30 extends through the bearing block 22. Therefore, a notch effect generated by the gap 28 can be prevented in the bottom 29. Furthermore, the gap 28 is completely filled with aerogel 31. The hidden veneer layer 32 of dense laminated wood may extend laterally, longitudinally, or parallel to the gap 28.

Fig. 6 shows a support block arrangement 33 consisting of a plurality of

blocks

34 and 35.

Blocks

34 and 35 are glued to each other and form support block 22 as described in fig. 3 to 5. Aerogel 31 is disposed within a gap 37 extending orthogonally to support side 36. The pairs 39 of

blocks

34 and 35 are then arranged in a row so as to form a bonding gap 40, the additional bonding gap 40 being completely filled with synthetic resin 38 so as to firmly connect the

blocks

34 and 35 of the adjacent support blocks 22.

Fig. 7 shows a support block 41, the support block 41 forming a floating support 42 for a tank (not shown). The support block 41 is formed of an upper block 43 and a lower block 44, with an intermediate plate 45 made of stainless steel. The upper block 43 and the lower block 44 are movable relative to each other along a plate 45. The lower block 44 forms a base 46 for resting on a surface and the upper block 43 forms a support side 47 for supporting a can body. In the bearing side 47, a gap 48 is formed, which gap 48 extends between

lateral surfaces

49 and 50 of the upper block 43. The gap 48 is completely filled with aerogel 51.

Fig. 8 shows a support block 52, which support block 52 may form a fixed support for a tank (not shown). The support block 52 is formed of a first block 53 and a second block 54, the first block 53 being connected to the second block 54 via bolts 55, the bolts 55 being made of dense laminated wood. The bolts 55 are each inserted into recesses 56, and are glued by means of synthetic resin, each recess 56 being formed in the first block 53 and the second block 54 by milling. The bolt 55 is surrounded by a plate 57, which plate 57 determines the distance from the first block 53 to the second block 54, thus forming a gap 58. The gap 58 thus extends over the entire circumference of the bearing block 52. The plates 57 are also glued to each other by gluing on the first block 53 and the second block 54 by means of synthetic resin. The gap 58 thus created is filled with aerogel 59. It is noted that the embodiment shown in the previous figures may be formed by the bearing blocks 52 by means of the bearing blocks having a circumferential gap 58.
