Definitions

  • the present invention relates to an apparatus according to claim 1 for heating mats based on incoherent wood material.
  • This heating step is generally implemented by means of the insertion, along the production line, upstream of the press or occasionally right inside of it, of apparatuses for injecting steam at at least one of the main faces of the mat, the mat itself being made to advance in the horizontal position resting on its underside.
  • the plate furthermore has inner heating channels defined in proximity to the lower surface, in order to even out its temperature and prevent thermal deformations thereof.
  • DE 10207573 C1 discloses an apparatus that has, at the input to the press, at least one plate for injecting steam at one of the faces of the mat, preceded by an extractor hood for removing the air held by the particles of the mat and facilitating the subsequent penetration of the steam.
  • a steam heating apparatus is disclosed in document US 4 923 555 .
  • EPA 09425027.1 discloses an apparatus for injecting dry saturated steam on a mat upstream of the point of input to a press, provided with at least one dispensing assembly provided with a plurality of outlets of the steam at one of the main faces of the mat.
  • Such assembly basically consists of one or more steam supply channels connected with the outlets and comprises a monolithic body made of heat-conducting material for supporting the channels which is crossed by one or more ducts for the passage of a heating fluid, the purpose of which is to yield heat to the channels in order to inhibit the formation of condensation inside them and, therefore, reduce the risk of the mat's coming into contact with condensation resulting in the formation of defective mats.
  • the aim of the present invention is to eliminate the above mentioned drawbacks in the background art, by providing an apparatus for heating mats based on incoherent wood material by means of steam injection, that makes it possible to dispense exclusively dry or superheated saturated steam, thus avoiding excessively wetting the mat or carrying along condensation in contact therewith.
  • an object of the present invention is to obtain, for the same steam supplied, an increase in the heat energy yielded to the mat and a reduction in the water content thereof compared to known apparatuses and, therefore, an increase in the productivity of the subsequent baking step of the panel in a press.
  • a further object of the present invention is to provide a simple structure, that is easy and practical to implement, safe in use and effective in operation, and low cost.
  • the present apparatus for heating mats based on incoherent wood material comprising at least one assembly for dispensing a fluid heating medium comprising dry saturated steam, which is provided with a plurality of outlets for said fluid medium which are adapted to be positioned at at least one of the main faces of a mat based on incoherent wood material in transit along an advancement direction, the dispensing assembly comprising at least one body for delimiting at least one chamber for propagation of the fluid medium, which is associated and connected with said outlets, characterized in that said outlets are associated directly with a wall of said body and in that it comprises means for heating said wall which are associated with said body and are arranged inside said chamber directly in contact with said wall, so as to achieve saturation of the steam contained in the fluid medium in output from the outlets, in the event of reduction in the titer in passing through the dispensing assembly, or its superheating.
  • the reference numeral 1 generally designates an apparatus for heating mats based on incoherent wood material.
  • the apparatus 1 is designed to be used along production lines of panels of wood material, upstream of the input to the baking device, in order to obtain a pre-heating of the mats, or directly inside them. Furthermore, the apparatus 1 can be combined with a perforated presser belt P of the type conventionally used upstream of the input to the press, as shown in Figure 1 , and with an optional further perforated supporting belt arranged below the mat, i.e. to constitute a self-contained device.
  • the apparatus 1 uses a fluid heating medium substantially in the gaseous state and comprising dry saturated steam optionally mixed with superheated steam and/or hot air.
  • the apparatus 1 comprises at least one assembly 2 for dispensing the fluid heating medium provided with a plurality of outlets 3 thereof which are adapted to be arranged at at least one of the faces of a mat M in transit along an advancement direction A.
  • each outlet 3 is convergent with the direction of travel of the fluid medium, having an inlet that is wider than the outlet. In this way a diffused progression of the jet of fluid heating medium is obtained, thus preventing the furrowing of the mat M in transit, and the fouling, and hence the risk of clogging, of the outlets 3 is reduced.
  • the term "mat” designates a semi-finished product obtained from the formation of a mixture of wood particles mixed with suitable thermosetting or thermoplastic glues.
  • the mat M is essentially parallelepiped in shape and is made to advance along the production line in the horizontal position.
  • faces is thus used to designate the two largest surfaces of the mat, one arranged above and the other below in the advancement configuration.
  • the dispensing assembly 2 comprises at least one body for delimiting at least one chamber for propagation of the fluid medium, which is associated and connected with the outlets 3.
  • outlets 3 are directly associated with a wall 8 of the body that is adapted to be placed in contact with the mat M in transit and the apparatus 1 comprises heating means 9 associated with the body and arranged inside the respective chamber directly in contact with the wall 8, so as to achieve the saturation of the steam contained in the fluid medium in output from the outlets 3, in the event of reduction in the titer in passing through the dispensing assembly 2, or its superheating.
  • the dispensing assembly 2 comprises at least one first body 4 for delimiting at least one first chamber 5 for the inflow and propagation of the fluid medium associable with means for feeding thereof, not shown since they are of the traditional type, and at least one second body 6 for delimiting at least one second chamber 7 for the propagation and outflow of the fluid medium associated and connected with the outlets 3.
  • the first and the second chamber, respectively, 5 and 7 are mutually in fluid communication and the second chamber has a greater volume than the first so as to obtain an isenthalpic expansion of the steam contained in the fluid heating medium in the passage from one to the other with consequent increase in the titer of the steam, according to the known properties of saturated steam as per the Mollier Diagram, in the event of reduction in the titer in passing through the first chamber 5.
  • the dispensing assembly 2 can comprise a different structure for example constituted by a single body for delimiting a single chamber for propagation of the fluid medium, communicating both with the supply means and with the outlets 3.
  • the first and the second body, respectively, 4 and 6 are box-like in shape and are made of heat-conducting material.
  • outlets 3 are obtained directly at a wall 8 of the second body 6 that is thin, so as to render the second chamber 7 immediately communicating with the outside environment and, therefore, with the mat M and obtain a diffused and non-linear progression of the jets of steam flowing out from the outlets 3.
  • the heating means 9 are associated with the second body 6 inside the second chamber 7 and comprise at least one duct 10 for the passage of a second fluid heating medium arranged in contact with the wall 8 and connected thereto by means of fastening elements 11 interposed between the duct 10 and the wall, which are made of heat-conducting material and are elastically deformable even after heat stresses (harmonic steel). In this way the fastening elements 11 are always kept in contact with the duct 10, from which they absorb heat, and with the wall 8, to which they yield heat.
  • each fastening element 11 is constituted by a central portion 11 a, which is arched so as to define a seat for accommodating the duct 10 and which envelops so as to adhere to a sectional portion of the duct, and by two rectilinear end portions 11b, arranged at opposite ends of the central portion 11a and connected thereto, which are positioned so as to adhere to the wall 8 and are fixed thereto by means of mechanical connection elements, welding or the like, not shown.
  • the end portions 11b must be fixed to the inward side of the wall 8 of the second chamber 7 so as not to create breaks in continuity on the outward side of the wall in contact with the mat M.
  • each fastening element 11 absorbs heat from the duct 10 and transfers it to the end portions 11b which yield it to the wall 8, so as to increase the exchange of heat with respect to that which would occur between the duct 10 alone and the wall, since the fastening elements 11 make it possible to recover and transfer to the wall 8 part of the heat which otherwise would be dispersed in the second chamber 7 and not yielded directly to the wall.
  • the duct 10 is also made of heat-conducting material in order to ensure the transmission of the heat to the wall 8 and, specifically, in proximity to the peripheral region of the outlets 3, so that the outflowing steam is necessarily heated thus increasing its titer, if in passing through the dispensing assembly 2 the saturated steam contained in the fluid medium has undergone a reduction in the titer, or becoming superheated, if the saturated steam had been maintained in the dry state.
  • the duct 10 is coiled so as to cover the wall 8 in an irregular manner. Alternatively there could be a plurality of ducts 10.
  • outlets 3 are distributed in one or more rows that are transversal to the advancement direction A in the regions of the wall 8 that are free from the duct 10 and from the fastening elements 11.
  • the second fluid heating medium used can be steam, supplied and drained through a circuit that is separate from the one used in the dispensing assembly 2 for heating the mat M, or water, diathermic oil or the like.
  • arrows show the path of the second fluid heating medium through the duct 10.
  • the positioning of the duct 10 close to the wall 8 is particularly advantageous in that it makes it possible to prevent cooling and, therefore, reduction in the titer of the steam flowing out from the outlets 3 as a consequence of the removal of heat taken away by the mat M in transit and by the optional interposed belt N.
  • the heating means 9 could comprise at least one electric resistor associated in contact with the wall 8 and fixed by means of connector elements of the type described above.
  • the apparatus 1 comprises at least one vent 12 connecting the first chamber 5 to the second chamber 7 and diffuser means 13 associated with the vent for distributing the steam inside the second chamber 7.
  • the apparatus 1 can comprise a single dispensing assembly 2 arranged in contact with one of the faces, upper or lower, of the mat M or, more preferably, it can be provided with two dispensing assemblies 2 of which one below 2a and one above 2b arranged with the respective walls 8 provided with outlets 3 in contact, respectively, with the the lower and upper faces of the mat M in transit, the walls 8 being flat.
  • the two dispensing assemblies 2 are designed with particular contrivances for enabling the collection by gravity and evacuation of any quantities of condensation formed inside the chambers 5 and 7 for the lower dispensing assembly 2a and for preventing the formation of condensation which by gravity would risk falling on the mat M through the outlets 3 for the upper dispensing assembly 2b.
  • the first and the second chamber, respectively, 5 and 7 are substantially linear in extension.
  • the first and the second body, respectively, 4 and 6 are constituted by respective box-like elements that are parallelepiped in shape and arranged with the longitudinal axis thereof horizontal and transversal to the advancement direction A.
  • the first body 4 is arranged inside the second body 6 and has a plurality of vents 12 constituted by respective openings defined at the upper portion thereof and distributed along its length.
  • the diffuser means 13 comprise a mesh 14 for covering each vent 12 and a diaphragm 15 shaped like a pan and supported by the first body 4 inside the second chamber 7 at each vent 12, so as to obtain a diffusion of the steam inside the second chamber with consequent expansion, to prevent the steam from flowing out from the outlets 3 directly. Furthermore, the diffuser means 13 make it possible to fragment any drops of condensation contained in the fluid medium thus favoring their re-evaporation. For this reason the diaphragms 15 can also be made at least partially from mesh.
  • the first body 4 is provided, in proximity to the lower face, with slits 16 for the outflow of any condensation that has formed inside the first chamber 5 and collected on the bottom thereof. Through the slits 16 the condensation falls on the bottom of the second chamber 7 from which it can then be evacuated.
  • the upper dispensing assembly 2b ( Figures 1 , 3 , 4 , 6 ), on the other hand, comprises at least one chamber 17 that is heated and arranged in contact with at least one between the first and the second body, respectively, 4 and 6 and isolated, in terms of fluid dynamics, from the first and from the second chamber, respectively, 5 and 7.
  • the chamber 17 is crossed by a third fluid heating medium, which can be steam, supplied and drained through a circuit that is separate from the one used in the dispensing assembly 2 for heating the mat M, water, diathermic oil or the like.
  • a third fluid heating medium which can be steam, supplied and drained through a circuit that is separate from the one used in the dispensing assembly 2 for heating the mat M, water, diathermic oil or the like.
  • the supply and draining circuit can coincide with the one for the second fluid heating medium used by the heating means 9.
  • the chamber 17 is interposed between the first and the second body, respectively, 4 and 6 so as to yield heat to both the chambers 5 and 7 and to the steam contained in them.
  • the vents 12 are constituted by respective ducts passing through the chamber 17.
  • the apparatus 1 comprises redirection means arranged inside the vents 12 to give a helical motion to the steam along each of them. In this way, as a result of the centrifugal effect, any condensation carried along by the steam in passing through the vents 12 is driven against the walls thereof, which are heated by the chamber 17, thus determining their re-evaporation.
  • the diffuser means 13 are constituted by pan-shaped diaphragms 18 supported inside the second chamber 7 at each vent 12 in order to favor the propagation of the steam inside the second chamber 7 with consequent expansion, thus preventing the immediate outflow through the outlets 3, and the fragmentation of any drops of condensation thus favoring their re-evaporation.
  • the first body 4 is constituted by a plurality of tubular sections 19 that are mutually connected to define a first chamber 5 with non-rectilinear development and a steam path following an open line. Furthermore, the tubular sections 19 are adjacent to the chamber 17. In this way, in passing through the first chamber 5 heat is yielded to the steam along all of the path, thus reducing the formation of condensation.
  • the vents 12 are defined along the end tubular sections 19a.
  • tubular sections 19 can be circular in cross-section ( Figure 1 ) and thus define a region of contact with the wall delimiting the chamber 17 that is limited to one generating line, or prismatic in cross-section ( Figures 3 , 4 , 6 ), for example square, and can each be placed with a respective longitudinal face in contact with the wall so as to enlarge the area of contact and increase the transmission of heat.
  • baffle elements (not shown) can be provided, accommodated inside the first chambers 5 so as to impart a turbulent motion to the steam inside them, thus forcing it to strike the chamber 17 so as to increase the transmission of heat to the steam.
  • the steam is fed into the first chamber 5 and from this it propagates to the second chamber 7 through the vents 12, undergoing an isenthalpic expansion with consequent increase in titer if the dry saturated steam has undergone a reduction in titer in passing through the first chamber 5.
  • the steam receives heat from the heating means 9 thus further increasing its titer, if necessary, or becoming superheated.
  • the steam is fed into the two first chambers 5, travelling through the tubular sections 19 heated by the chamber 17 until it reaches the end tubular sections 19a, to then enter along the vents 12, which are also heated, and exit into the second chamber 7, also heated, and expanding.
  • baffle elements positioned along the tubular sections 19 and the redirection means provided along the vents 12 force the steam to strike the walls heated by the chamber 17 thus increasing the absorption of heat by the steam.
  • the apparatus 1 could have a single dispensing assembly 2 arranged below, or two identical dispensing assemblies 2 of the type of the upper dispensing assembly 2b described previously and provided with a chamber 17.
  • the invention as described achieves the intended aim and objects and, in particular, attention is drawn to the fact that the apparatus according to the invention makes it possible to prevent the carrying along of condensation to the mat and to optimize, for the same amount of dry saturated steam supplied, the share of heat yielded thereto compared to known apparatuses, in that the outflowing steam is in the saturated dry or superheated state.
