    DEVICE AND METHOD FOR DRYING CALCIUM SILICATHYDRATE
    BASED PLATES
    Domain of the invention
    The present invention relates generally to devices and methods for drying calcium silicate hydrate (CSH) based plates. More specifically, the present invention relates to devices and methods for drying CSH-based plates with a reduced risk of damage.
    BACKGROUND OF THE INVENTION
    Furnaces for drying calcium silicate hydrate-based plates, hereinafter referred to as CSH-based plates, with best known examples of Xonotlite and Tobermorite-based plates, are known in the art.
    In contrast to cement plates, CSH-based plates are usually dried up in an oven. The present invention relates to the latter type of furnaces. A problem with such ovens is that sometimes cracks or dents occur on the plates caused in the drying oven.
    Summary of the invention
    It is an object of the present invention to provide a drying oven and a method for drying calcium silicate hydrate (CSH) based plates, with a reduced risk of damage to the plates caused in the drying oven.
    These and other objects are achieved by a drying oven and a method according to embodiments of the present invention.
    The invention provides a drying oven for drying calcium silicate hydrate (CSH) based plates, comprising: a displacement system with a plurality of transverse profiles to which at least two support profiles are each attached to support the CSH-based plates on their back, and wherein the drying oven further comprises a tilting mechanism to tilt the CSH-based plates early so that they rest with their front side against a downstream support profile.
    In a first aspect, the present invention provides a drying oven for drying calcium silicate hydrate (CSH) based plates, comprising: a displacement system for moving the CSH based plates from an entrance of
    BE2018 / 0048 the drying oven to an outlet of the drying oven in a continuous direction, the plates being in a substantially vertical position, the displacement system comprising at least a plurality of transverse profiles to which at least two support profiles are each attached for supporting a back side of one CSH each -based plate; characterized in that the drying oven further comprises a tilting mechanism adapted to cause the CSH-based plates to tilt so that they support against a downstream support profile; wherein the tilting mechanism is provided to tilt the CSH-based plates at a time when the support profiles associated with the plate to be tilted are still in a substantially vertical position. The tilting mechanism comprises a compressed air system, which is provided to tilt the plate by exerting a compressive force by means of compressed air. The compressed air system comprises one or more nozzles that are arranged above a horizontal interface on the plates. This horizontal plane is of course understood as the horizontal interface on the top of the plates moving through the drying oven.
    According to embodiments, the one or more blow nozzles may be mounted so that the support profiles pass the blow nozzles laterally. The blow nozzles are, as it were, mounted between the support profiles. According to embodiments, the one or more blow nozzles may optionally be adjustable in height, to allow different types of plates of different lengths to be dried in the oven. With every run of a plate type; the height can be adjusted to tilt the plates.
    According to embodiments, the one or more blow nozzles can be mounted on support profiles above the horizontal interface.
    Substantially vertical position of the support profiles or plates means that they are at an angle of between 0 and 15 ° with respect to the vertical or perpendicular.
    Tilted backwards means tilted in the direction opposite to the flow direction.
    In some embodiments, the displacement system comprises at least two closed chains for displacing the transverse profiles.
    It is an advantage of deliberately and prematurely tilting the plate when the support profiles are still in a substantially vertical rearward tilted position, and the plate is therefore also in a substantially vertical rearward direction
    BE2018 / 0048 is in a tilted position, because the angle that must be tilted, and the time at which tilting is performed, are much better controlled, in contrast to the state of the art, where the moment of tipping over is not precisely determined, and in addition the angle of rotation and impact on the plate that falls over is greater than with the controlled tilt.
    It is an advantage of the premature tilting, while the support profiles are still in substantially vertical backward tilted position, that the risk of damage is drastically reduced, or even completely excluded.
    In one embodiment, the support profiles are provided to support the CSH-based plates on their rear side such that these plates form a first angle of inclination of 5 ° to 15 ° with respect to a vertical direction, and the support profiles are provided to support the tilted CSH support based plates on their front side such that these plates form a second angle of inclination of 1 ° to 15 ° with respect to a vertical direction.
    By tilting the plate at a moment when it is still in a substantially vertical position, only a very small force is required to move the center of gravity of the plate beyond the supporting point. Indeed, depending on the chosen first angle of inclination, this force is only a fraction of the weight of the plate
    In one embodiment, the first and / or the second slope angle is an angle in the range of 1 ° to 10 °.
    In one embodiment, the tilting mechanism comprises a compressed air system, which is provided to tilt the plate for exerting a compressive force by means of compressed air.
    In one embodiment the compressed air system comprises at least one compressed air mouth provided for discharging compressed air at a third angle of inclination from 0 ° to 45 °, for example from 0 ° to 30 °, for example from 10 ° to 30 °, or even in the range of 0 ° up to 20 ° with respect to a horizontal plane. This angle is defined as the angle between the horizontal plane in the direction opposite to the moving direction, and the vertical direction upward.
    In one embodiment, the drying oven further comprises at its entrance a receiving mechanism for receiving plates to be dried from a supply system and transferring them to the displacement system; and the drying oven at its exit further comprises a take-off mechanism for transferring dried plates from it
    BE2018 / 0048 transport system to a drain system, and the tilting mechanism is located between the pick-up mechanism and the pick-up mechanism.
    In one embodiment, the displacement system comprises at least two closed chains for displacing the plurality of transverse profiles, said chains traversing a rotation zone on both sides of the drying oven with the chains making a rotation of about 180 ° about an axis transverse to the direction of travel. In one embodiment, the tilting mechanism is located in a zone of 3 meters in front of the rotation zone at the level of the take-off mechanism, or even in a zone of 2 or even 1 meter in front of the rotation zone at the level of the take-off mechanism.
    In one embodiment, the CSH-based plates have a length of 100 to 300 cm, and a width of 50 to 150 cm, and a thickness of 2 to 30 cm, and a mass of 10 to 50 kg.
    Concrete plates with the following dimensions are mentioned as a concrete example:
    1.2 m (width) x 2.5 m (length) x 15 mm (thickness) used, but other dimensions are also possible.
    In a second aspect, the present invention provides a method for drying CSH-based plates in a drying oven, comprising the steps of:
    - moving the CSH-based plates from an entrance to the drying oven to an exit from the drying oven in a flow direction where the plates are in a substantially vertical position, using a displacement system comprising at least a plurality of transverse profiles (each of which has at least one two support profiles are attached for supporting a rear side of one CSH-based plate in each case;
    characterized in that the method further comprises the step of:
    - tilting the CSH-based plates so that they support against a downstream support profile on the at least two support profiles associated with the plate to be tilted, are still in a substantially vertical backward tilted position with the step of tilting applying a force by means of compressed air, which compressed air system comprises one or more nozzles which are arranged above a horizontal interface on the plates.
    BE2018 / 0048
    According to embodiments, the method for drying CSH-based plates in a drying oven comprises the steps of: moving the CSH-based plates from an entrance of the drying oven to an output of the drying oven in a flow direction with the plates in a substantially vertical position using a displacement system comprising at least two closed chains with a plurality of transverse profiles to which at least two support profiles are each attached for supporting a rear side of one CSH-based plate; characterized in that the method further comprises the step of: tilting the CSH-based plates so that they support against a downstream support profile at the time that the at least two support profiles associated with the plate (101) to be tilted, are still in a substantially vertical position.

    Numerous specific details are set forth in the description provided here. It is, however, understood that embodiments of the invention can be practiced without these specific details. In other cases, well-known methods, structures and techniques have not been shown in detail to keep this description clear.
    In the present invention, the terms transport system and displacement system are used as synonyms.
    FIG. 1 shows a schematic representation of a known drying oven 100 for drying calcium silicate hydrate (CSH) based plates 101 in side view, and FIG. 2 in perspective view. The best known examples of CSH-based plates are perhaps plates which include as CSH Xonotlite and / or Tobermorite. It has been known for years how such plates can be manufactured. The drying process must be forced because otherwise it will take too much time.
    In contrast to drying cement plates, which are usually air-dried, CSH-based plates can be dried in a type of oven as shown in FIG. 1 and FIG. 2, in which the plates are substantially upright, because the plates 101
    BE2018 / 0048 are already sufficiently strong after forming to be able to stand upright, but are not yet dry and cured. Such drying usually takes place at a temperature in the range of 100 ° C to 170 ° C, preferably between 120 ° C and 150 ° C, and the plates usually remain in the oven for a period of about 10 to 20 hours so that the excess water is evaporated.
    The furnaces 100 typically include a displacement system 102 (also called a conveying system) with two or more closed chains 105, 106 spaced apart (e.g., about 2.5 m apart) in the depth direction of the plane of FIG. . 1, and mounted on a plurality of gears that guide the chains. The gear wheels are preferably driven stepwise. Only one chain 105 and two such sprockets are shown in FIG. 1, in particular one gear 116 at the input 103 and one gear 117 at the output 104 of the drying oven 100, but of course additional gears or other supporting means can be arranged between them.
    The at least two chains 105, 106 are interconnected by means of a plurality of transverse profiles 107, e.g. in the form of substantially flat metal plates. As the chains 105, 106 rotate, these transverse profiles 107 assume different positions. For example, when a cross section is at the top or bottom, it will be oriented substantially parallel to a horizontal plane, but near the oven entrance 103 (left in FIG. 1) and near the oven exit 104 (right in FIG. 1) ) these plates make a rotational movement of 180 ° about the axis of the gear wheels 116, 117 shown. Use is made of this rotation to receive new plates to be dried in the conveyor system 102 and to bring them into an upright position, and to bring already dried plates to a horizontal position and remove them from the conveyor system 102 on ways known in the art.
    A plurality of support profiles 108 are attached to the transverse profiles 107. These support profiles 108 have a longitudinal direction that forms a first angle α relative to a perpendicular to the plane defined by the transverse profile 107 to which the relevant support profiles 108 are attached, the first angle α preferably being in the range of 5 ° to 15 °, e.g. in the range of 5 ° to 10 °, and for example equal to about 6.5 °. In other words, the CSH-based plates 101 to be dried are transported substantially vertically through the oven 100, or rather, they are transported slightly sloping backwards through the oven, supported on their back side 109 by the support profiles 108.
    BE2018 / 0048
    Known furnaces have a height of, for example, 3 to 5 m, and a length of, for example, 20 to 30 m. The plates 101 are preferably introduced into the oven at approximately half height, and taken out of the oven, as can be understood from FIG. 1.
    FIG. 1 also schematically shows a feed system 112 (at an input 103 of the oven) that delivers new CSH-based plates to be dried to an input of the oven, which plates 101 are then transferred to the oven displacement system 102. As shown schematically, new plates to be dried are supplied almost horizontally, e.g. via caterpillars or conveyor belts or chains or rollers or in any other suitable manner. This supply system 112 is not an essential part of the oven 100, but it does work closely with it.
    FIG. 1 also shows schematically a collection system 113 (at an exit 104 of the oven) that discharges dried CSH-based plates from the drying oven. As shown schematically, dried plates are preferably also discharged substantially horizontally.
    As explained above, the displacement system 102 as described above automatically ensures that plates supplied horizontally are brought to an upright, almost vertical position, and held therein over substantially the entire length of the oven, and are brought back to a horizontal position on the oven exit 104.
    Finally, it should be mentioned that chains 105, 106 do not run continuously in practice, but step by step. Specifically, a new plate 101 to be dried is repeatedly, e.g. periodically (e.g. every minute) presented to the input 103, where it is transferred to the displacement system 102, and a dried plate is presented to the output 104 at the same time period, where it is removed from the displacement system 102, after which the chains 105, 106 move through one step or stroke, so that a next plate 101 can be presented at the entrance and the exit.
    FIG. 3 outlines a problem of known drying ovens such as that shown in FIG. 1 and FIG. 2. Indeed, it has been found that some CSH-based plates that have been dried with a drying oven such as those of FIG. 1 and FIG. 2, show cracks or damage. Research has shown that these cracks or damage occurred mainly in places that correspond to the positions of the support profiles 108. Further research has shown that these damage can largely be attributed to
    B E2018 / 0048 sometimes the CSH-based plates fall over abruptly, especially when they change from a substantially vertical orientation to a horizontal orientation as shown at the top right in FIG. 3. It will be appreciated that propelling the chains 105, 106 with the transverse profiles 107 and support profiles 108 when loaded with a plurality of CSH-based plates 101 requires enormous force, and that this propulsion sometimes occurs jerky. As a result of such a shock, a given plate 10x may abruptly become unbalanced, and accelerate as a result of its own weight, and bump into the front sections 110b at its front 110 with full force. CSH-based plates, in particular Xonotlite and / or Tobermorite plates, are relatively brittle and porous, and are therefore not always resistant to such impact, which can lead to the mentioned cracks or dents.
    FIG. 4 shows a schematic representation of a drying oven 400 according to the present invention, wherein this problem is solved.
    The present invention proposes that the tilt, which must in any case take place in order to deliver the dried product to the outlet 104 in a substantially horizontal position, not suddenly and uncontrolled to take place near the outlet, but to allow this tilt to take place earlier, at a time when such tilting is actually not yet necessary, e.g. approximately halfway between the entrance 103 and the exit 104, but in any case before the preceding transverse profile 108b starts to tilt from the horizontal position, and consequently the associated support profiles from the almost vertical position. The controlled tilt is preferably effected near the turning point of the transport system 102 near the exit 104 of the oven. Thus, the plates are supported as long as possible over their full height by the rear support profiles 108a (the plate is tilted slightly backwards), and the plate 101 is tilted against the front support profiles 108b at the end of the drying process, where it will rather have a point contact between the plate surface and the apex of these front support profiles 108b.
    This controlled tilting has the advantage that the plate is tilted from a substantially vertical position, more specifically from a first (rearward-facing) angle α, to another substantially vertical position, more specifically a second (forward-facing) angle β, but both angles are relatively small, for example, both smaller than 15 °, or even smaller than 10 °, so that the plate has no chance of falling and accelerating. Moreover, it appears
    B E2018 / 0048 surprisingly that the angle (α + β) to be tilted in this case (FIG. 4) is considerably smaller than the angle φ (see FIG. 3) over which the plate would tilt uncontrollably in the known oven of FIG. 1 and FIG. 2, further reducing the impact. The support profiles 108 preferably have a circular or elliptical cross-section or a rectangular cross-section with rounded corners, so that sharp edges are avoided.
    To achieve the second angle β in the proposed range, the support profiles 108 must be placed at a suitable distance d2 from each other, as shown in FIG. 4. Specifically, the first angle α is formed between the plate 101 and a vertical when the plate in question rests with its backside 109 against the support profile 108a located behind (upstream of) the plate, and the second angle β is formed between the plate and a vertical one when the plate in question rests with its front side 110 against the support profile 108b which is located in front of (downstream of) the plate in question. A desired second angle β can be selected by choosing a suitable length H of the support profiles 108 and / or a suitable distance d2 between the support profiles. The person skilled in the art can easily calculate this or can easily find suitable values for H and / or d2 experimentally. d2, which is typically the stitch length of the chain or a multiple of the stitch length of the chain, is, for example, 15 cm.
    Thus, as indicated above, by choosing the first angle α in the range of 5 ° to 15 °, e.g., about 10 ° or about 6.5 °, and by choosing the second angle β in the range of 1 ° to 15 °, for example between 2 ° and 5 °, the plate therefore has to be tilted about its equilibrium point by only an angle of a few degrees. The great advantage of this is that when the pre-tilted plate has reached the exit 104 of the oven 400, it already rests against the support profiles 108b which is located in front of (downstream of) the relevant plate, and therefore no longer with full force can collide, avoiding damage. Tests have shown that the pre-tilted plate near the exit 104 will still slide gently until it will rest completely on the downstream support profile 108b, as represented by the arrow B, but this shift causes no more problems.
    Now that the principle of the underlying invention has been explained, some specific tilting mechanisms will be explained in more detail, but the invention is not limited thereto, and other mechanisms can also be used.
    BE2018 / 0048
    FIG. 5 shows a first exemplary mechanism for tilting the plates, one by one, using a compressed air system. In FIG. 5 shows a nozzle 111 (the compressed air lines are not shown), which is arranged above a horizontal interface on the plates 101, which is also arranged above a horizontal interface on the support profiles 108b, and which is oriented such that the air discharged from it essentially has a direction that forms an angle ω with the horizontal tangent in the range of 10 ° to 30 °. The person skilled in the art can experimentally find a suitable diameter and pressure which is sufficiently large to cause the plate 101 to tilt. The starting time at which the compressed air must be applied and the duration can also be determined experimentally. Possibly, multiple nozzles 111 are used at the same time, scattered throughout the width of the plate (in the depth direction of the blade of FIG. 5). By using a number of N nozzles, e.g., N = 2 or N = 3 or N = 4 or N = 5 or even more than five, the total force exerted on the plate 101 to tilt it with the same factor N greater. However, the use of one nozzle and a compressed air with a pressure of a few barg, for example 2, 3, 4 or 5 barg, may be sufficient to achieve the desired effect. Barg stands for bar gauge or overpressure, expressed in bar, on top of the ambient ambient pressure.
    FIG. 6 shows another exemplary mechanism for tilting the plates one by one, using a compressed air system. In FIG. 6 shows a nozzle 111 (the compressed air lines are not shown), which is arranged above a horizontal interface on the plates 101, which, however, is arranged below a horizontal interface on the support profiles 108b, and which is oriented such that the air discharged from it essentially has a direction that forms an angle ω with the horizontal tangent in the range of 10 ° to 45 °. The person skilled in the art can experimentally find a suitable diameter and pressure which is sufficiently large to cause the plate 101 to tilt. The starting time at which the compressed air must be applied and the duration can also be determined experimentally. Possibly, multiple nozzles 111 are used at the same time, scattered throughout the width of the plate (in the depth direction of the blade of FIG. 5). By using a number of N nozzles, e.g., N = 2 or N = 3 or N = 4 or N = 5 or even more than five, the total force exerted on the plate 101 to tilt it with the same factor N greater. However, the use of one nozzle and a compressed air with pressure of a few barg, for example 2, 3, 4, 5 or 6 barg, may be sufficient to achieve the desired effect. Barg
    B E2018 / 0048 stands for bar gauge or overpressure, expressed in bar, on top of the ambient ambient pressure.
    In the examples shown by means of Figures 5 and 6, the nozzle is the end of a 1 inch to 2 inch diameter tube, the end of which was deformed into an elliptical opening 5.
    For each of the tilting mechanisms shown in figures, the oven further comprises a drive unit and / or a control unit (not shown) which controls the tilting mechanism, e.g. stepwise, in line with the movement of the plates.
    Although specific embodiments of the invention have been described, various modifications are possible, which fall within the scope of the claims, in the spirit of the present invention.
