    IMPROVED SHUTTER COVER FOR STORAGE DEVICE AND TRANSPORT VEHICLE WITH SUCH STORAGE DEVICE
    Technical field
    The invention relates to an improved hatch cover for a storage device, such as for example a tank or a container mounted on a truck or trailer. The invention also relates to a transport vehicle, such as for example a trailer, with a storage device in which an improved hatch cover is provided.
    BACKGROUND OF THE INVENTION
    Storage devices suitable for mounting on a vehicle such as a trailer truck and used for storage of material such as bulk products (e.g. cereals) typically comprise a tank provided with an opening, usually with a cover system, for loading the (bulk) products . Such products are pressurized within such a storage device or tank whenever the product is to be unloaded at, for example, farmers or customer locations in, for example, a container or silo. In principle, the higher the pressure, the faster the bulk material can be unloaded or unloaded. While in principle the acceptable pressure is determined by the materials and plate thickness used for the tank, in reality the weak points in such a construction determine the final pressure to be used.
    An important weak point is the opening through which the bulk products are poured into the trailer or tank thereof. The material of that point can indeed bend under pressure and even a small variation can lead to sealing problems and air pressure loss. This is particularly true in the case that sliding covers are used, which is preferred over other covers, given that they require less space above the tank and that they are quick and easy to open. Although the above problem is known in the art, the state of the art attempts
    BE2019 / 5033
    - 2 technique to solve the problem by applying additional reinforcements externally around the opening. However, such a solution is not satisfactory.
    In addition to being a delicate point in terms of pressure, and hence tension or tension acting on it, the opening or more particularly the hatch cover system comprising the opening of the tank also represents a design or architecture where the surface is not smooth and flattened is compared to other part of the tank. In other words, many corners and edges are included, and in particular are present in the tank when the hatch cover system, more particularly a sliding hatch cover system, is mounted substantially on the inside of the tank. Such a geometry with many corners and edges is very disadvantageous in the transport of, for example, bulk material such as grain or flour, while the material, for example grain or flour, can get stuck at the corners or edges, which easily leads to dirt and strong contamination or pollution in the tank. Such contamination is either absolutely not accepted or permitted for quality, standards, but also for safety reasons, and hence that those hatch cover systems with angular design require frequent maintenance, ie thorough cleaning of the tank. Figure 15 (a) depicts a hatch cover system in accordance with the state of the art, which is designed to be built or mounted from outside the tank. While Figure 15 (a1) substantially shows the outer surface 150 (ie, it is outside the tank) of the hatch cover system, Figure 15 (a2) is a view from the inside of the tank and thus essentially shows the inner surface 151 of the hatch cover system . The angles and edges that are clearly shown in this image are at least partially visible in the inner part of the tank and therefore cause problems with regard to contamination of bulk material. Such a design is therefore not GMP approved, whereby GMP stands for Good Manufacturing Practice and corresponding ditto regulation. In order to solve the problem of fouling, other hatch cover systems occur in the art, such as e.g. shown in Figure 15 (b) also designed to be built or mounted from outside the tank. However, another drawback is now apparent with this design of a remedy for dirt, and therefore GMP approved, because leads to rather high structures protruding on top of the tank as indicated by arrow 152. In other words, such a GMP approved hatch cover system, e.g. the sliding hatch cover system, with a smoothly finished inner part, protrudes largely far or
    BE2019 / 5033
    - 3 above the tank, which is also seen as a disadvantage. Indeed, the maximum dimensions of the tank or trailer must be respected for transport, or else for activities in an environment for loading or unloading bulk goods or other material.
    It is clear that the metric of concern is related to the efficiency of the transport, for example the amount of products transported per vehicle energy used, which is predominantly determined by the total weight, including the weight of the storage device. Consequently, work in a safe and secure manner, in terms of sealing, and precisely and efficiently, in terms of cleanliness, with a given tank or use it for both loading and transporting material, or else to dispose of its stored material under elevated pressure and while keeping any weight gain limited, poses an interesting technical problem.
    Object of the invention
    The object of the invention is to provide a hatch cover system for a storage device, such hatch cover system being, for example, a sliding hatch cover system, which is resistant to high pressure and contamination of (bulk) material within the storage device.

    Description of the invention
    BE2019 / 5033
    The invention provides a storage device provided with a first opening, for example for loading bulk products, storing and discharging them under (high) pressure. The storage device comprises a tank provided with a second opening. The storage device also comprises an access system provided with the first opening and adapted such that a part fits through the second opening. The access system is adapted for and mountable at least internally on the tank, in particular on a part of an inner wall of the tank.
    The invention is directed to the specific choice of materials, in particular material thicknesses, with a view to use under pressure, while considering the weight problem described above. In essence, the invention offers a clear design choice. The local opening or lid system problem is solved by providing a separate access system, specifically designed, while keeping the overall or global tank design, especially in terms of weight.
    Given the above design choice, the invention further focuses on the attachment of the access system, in particular with a view to the use of welds as an attachment technique. The invention specifically provides shape requirements that are selected to minimize the force or force component tangential to the inner wall where the second portion fits or is attached to the inner wall.
    It is worth emphasizing that in typical arrangements cylindrical tanks are used that further result when openings are provided therein, in special geometric shapes. The shape requirements as shown above also lead to specific geometries in such an arrangement.
    The invention relates to an improved hatch cover system, which is, for example, a sliding hatch cover system, which on the one hand is a kind of compromise to limit its height on the tank, and thus to place (a substantial) part thereof inside, on the other hand to eliminate the disadvantages. from inside the tank by a clean seal inside the tank.
    BE2019 / 5033
    Referring to Figures 1 to 7, the invention relates to a storage device 10 adapted to provide access through a first opening 20. The storage device comprises a tank 30 provided with a second opening 40 and an access system 50 provided with of the first opening 20 and which is arranged so that a part fits through the second opening 40. The access system 50 is adapted for and mounted at least internally or internally on the tank 30, in particular on a part of an inner wall of the tank 30.
    For example, as shown in a plan view and semi-cross-section of Figure 2, the storage device 10 has an access system 50 that may include a first portion 110 that provides the first opening 20 and is shaped to fit through the second opening. In addition, the access system 50 may include a second portion 100 configured to be mounted on a portion of an inner wall of the tank 30. By semi-cross-sectional view is meant that a portion of this view is a schematic representation of the cross-section of a tank 30 in which an access system 50 is mounted, although a portion of the access system 50 is depicted in its longitudinal view with the second portion 100 viewed as bent toward the inner surface of the tank 30. As shown, the first and second portions 110, 100 may be connected ; preferably the second portion 100 is completely mounted around its circumference on the inner wall of the tank 30. According to one embodiment, the shape of the second portion 100 is selected to minimize the tension force 200 (or its force component) thereon. In general, the size and shape of first and second portion 110, 100 including the first opening 20 within the first portion 110 is dependent on the size and shape of the second opening 40 as made within the tank 30, as well as depending on the pressure exercised during the unloading of bulk material.
    The access system 50, which represents a kind of casing surface (elliptical seal inside, on the inner wall of the tank 30), is not only designed for strength to absorb forces, but also serves to neatly close the part of the lid or part that ends in the inside of the tank 30, without any corners and edges which are not desirable because the dirt can accumulate therein. This rounded seal prevents contamination or contamination.
    BE2019 / 5033
    According to an embodiment, the tank 30 is made of a first material with a first thickness and the access system 50 is made of a second material with a second thickness. Furthermore, the materials and thicknesses are preferably chosen such that the strength of the tank 30 with the access system 50 against pressure is greater than the strength of the tank 30. The first and second materials of tank 30 and access system 50 can be fixed on the basis of of welding techniques, wherein, for example, part of the welding is performed at a location 120 where the second part 100 is connected to the inner wall of the tank 30.
    According to an embodiment, the tank 30 is partially cylindrical. According to another embodiment, the openings 20 are circular or elliptical. According to a further embodiment, the first opening 20 is circular or oval, while the second opening 40 is rectangular or square. With reference to the first opening 20 in particular, when we deviate from a small round hole, and thus think of other shapes such as oval holes or larger round holes, additional reinforcement in the area of the opening 20 is required, which is realized with the invention. Solutions in the art may be sufficient for small holes, but are not satisfactory when oval or large round holes for openings are desired. Openings that represent oval or large round holes are especially required to quickly and efficiently feed (bulk) material through the provided holes in the tank. Oval or large round holes mean more positioning margin and therefore less precision is needed in a supply pipe that is part of a number (or plural) thereof at a certain distance from each other.
    According to an embodiment, the storage device 10 is provided with a lid system 300 for the first opening 20, wherein such a lid system 300 is preferably provided with a sliding or slidable lid 310. Moreover, such a lid system 300 is preferably connected to or part of the access system 50.
    The invention also relates to a vehicle, comprising the storage device 10 as mentioned above, possibly with different forms of openings. According to an embodiment, such a vehicle is, for example, a trailer comprising a tank in which a plurality of access systems can be provided, possibly with different shapes
    BE2019 / 5033
    - dimensions and dimensions, depending, for example, on the use or application of the trailer, more particularly, for example, depending on the (un) loading station or the supply of bulk material. The inter-spatial distance between the multiple access systems may be the same or may differ, again depending on the use or application, or at the request of the customer.
    In a broader aspect, the invention also relates to a vehicle, comprising a storage device suitable for providing access through a plurality of first openings 20, comprising: (i) a tank provided with a plurality of second openings 40; and (ii) a plurality of access systems 50 provided with the plurality of first openings 20 and adapted to fit a portion of each of the plurality of access systems 50 respectively through one of the plurality of second openings 40, and therefore each of the plurality of second openings 40 with one of the plurality of first openings 20 (which is provided within the plurality of access systems 50). The plurality of access systems 50 are adapted for and mounted at least internally or on the inside of the tank 30.
    Referring now to Figure 8 and Figure 9, a further embodiment is illustrated of a storage device 10 for providing access through a circular manhole or first opening 20 in accordance with the invention, in cross-section or in longitudinal view, respectively. Although Figure 8 (a) shows the cross-section without lid 310, Figure 8 (b) illustrates the cross-section with lid 310 that is partially slid into the lid system 300 over the first opening 20, and therefore slightly extended over the tank 30. In Figure 8 further shows that the access system 50 wherein the first portion 110 is provided with the first opening 20, including the lid system 300, and the second portion 100 connected to the tank 30. In the embodiment, the first opening 20 is a circular manhole or circularly shaped hole, with a diameter d, while the second opening 40 is a square shaped hole, with side z as indicated in Figure 8 (a). The second part of the access system 100 which is connected to the tank 30 can for instance be attached to the tank 30 by welding. The welding, or a part thereof, can be performed at the location 120 where the second portion 100 is in direct communication with the inner wall of the tank 30. In Figure 9, where the longitudinal view is shown, the respective parts of the storage device are 10
    BE2019 / 5033
    - 11 also indicated, although curves or curved surfaces appear differently here. With the longitudinal view, the access system 50 including its first portion 110 and second portion 100 is now viewed from a different perspective, and thus more or other curved surfaces are now visible. While Figure 9 (a) shows the longitudinal view without lid 310, the illustration of Figure 9 (b) is provided with lid 310 slid into lid system 300 over the first opening 20.
    Figure 10 shows a perspective view of an embodiment of an access system 50 in accordance with the invention, with a circular manhole or first opening 20 with a diameter d, and not having a lid 310, as could be slid into the lid system 300 of the access system 50 comprising first and second portion 110, 100. The surrounding square or rectangle of the lid system 300, or the frame thereof, which more or less corresponds to the dimensions of the second opening 40 made in the tank 30 such that the access system 50 can partially fit through or be pushed through, has a side z1 and z2. In the case of a perfect square, which is, for example, the case with a circular manhole or first opening 20, z 1 is equal to z 2.
    Figure 11 shows a perspective view of an embodiment of an access system 50 in accordance with the invention, with an oval manhole or first opening 20 with small axis d1 and main axis d2, and not having lid 310, as could be slid in the lid system 300 of the access system 50 comprising first and second portion 110, 100. The enclosing rectangle of the lid system 300, or the frame thereof, which more or less corresponds to the dimensions of the second opening 40 made in the tank 30 such is that the access system 50 can partially fit through or be pushed through, has a width or short side z1 and a length or long side z2.
    For example, a large oval manhole is preferable in comparison with a small circular manhole to allow for less accuracy, for example when the tank of the trailer is filled with bulk material in a (un) loading station. The large oval manhole indeed provides a larger margin for the exact spot or hole in which it
    BE2019 / 5033
    - 12 bulk material must be deposited. However, choosing a large oval manhole is not that obvious. This large geometry in combination with the pressure of, for example, 2 bar required for the release of bulk material is quite challenging, and requires quite a bit of reinforcement of the architecture. In a first design in the development of the invention, this meant adding an additional plate to the access system from the art - as illustrated in Figure 15 - on top of the tank, but this resulted in too much overweight of the structure to be applicable here . In order to obviate the above technical problem, the addition of a type of reinforcement within the tank is chosen, in addition to providing a reinforcement with a certain curvature to absorb stresses or tensile forces when pressure is applied. This has the additional technical advancement that a smooth finish of the design is obtained on the inside of the tank, as required for GMP (Good Manufacturing Practice) regulation, which means that corners and edges are eliminated. With the access system mounted from the tank, at least partially according to an embodiment, the projecting part on top of the tank remains limited, and as a result, more bulk material could be transported within the tank, which is an additional advantage of the invention.
    Referring again to Figure 15 with illustrations of the access system in accordance with the art, Figure 15 will require built-in or built-up designs mounted from outside the tank, in the case of Figure 15 (a) require a square hole or second opening in the tank, while Figure 15 (b) requires a circular hole or a second opening in the tank. Square or rectangular openings in the tank require much more strength and reinforcement to absorb stresses and draw than circular or oval holes. Voltage profiles and simulations were performed during the development of the invention, so that applicable and resistant designs could be created.
    Figure 12 shows a perspective view of an embodiment of a storage device 10 according to the invention, with an oval manhole or first opening 20, provided with lid 310 in sliding or sliding open state such that the oval manhole or first opening 20 is visible . A rectangular second opening 40 is made in the tank 30 to provide sufficient space for creating an oval manhole or first opening 20 in
    BE2019 / 5033
    13 the access system 50. Because of the rectangular shape of the second opening 40, additional reinforcement is provided at the corners of the second opening 40, whereby the access system 50 is fitted. This reinforcement is done by adding a small round plate 316 to each of the corners. Such small circular plates 316 are, for example, welded to the outer surface of the tank 30. Additional or heavier material is also applied to the lid system 300, ie that a heavier structure of the lid system 300 itself is provided, as well as a further structure 314 with brackets. 315 added. The lid 310 is also reinforced with additional material, either rod or plate-like 311, 313, whether or not provided with hooks or brackets, or in a triangular shape 317. A circular hole with a globe cover 312 is additionally provided within the lid 310.
    Figure 13 shows a slightly different perspective view of the embodiment of a storage device 10 according to the invention, with an oval manhole or first opening 20, provided with lid 310 in slidable closed condition such that the oval manhole or first opening 20 is no longer visible on the outside of the tank 30.
    Figure 14 shows a further perspective view of the embodiment of a storage device according to the invention, with an oval manhole or first opening 20, provided with lid 310 in the slidable closed state. Here the oval manhole or the first opening 20 which is covered remains visible, of course, as seen from the inside of the tank 30. A smooth inner surface is provided in the tank 30, as required by GMP regulation.
