Definitions

  • Gas flame burners are arranged in casings for directly heating a portion of the chain run at a position spaced from the engagement with the chip material.
  • Each of the easings also include burner exhaust gas conducting channels for conducting the hot exhaust gases adjacent portions of the chain which are not impinged upon by the flame at a particular given time.
  • conduit means for the flame burner exhaust gases are provided for conducting the exhaust gases to heat the endless steel bands by way of Z-shaped channeled housings arranged at a position spaced from the casings for the flame burners and immediately adjacent the steel bands.
  • the invention relates to a continuously operating press for producing boards such as chipboards, fibreboards or the like with two superimposed endless belts comprising heatable plates articulated to one another and rotating about horizontal and parallel shafts whose facing sides are movable in the same direction particularly by drivable feed rollers and each endless belt is enveloped by a further heatable endless steel band. Presses of this general type are known (U.S. Pat. Nos. 2,926,719, 2,981,307).
  • the present invention contemplates a more economic manner of heating of the endless belts and steel bands than was hitherto possible.
  • the present invention also contemplates to permit heating in a relatively rapid manner to advantageously above 200C, as well as to increase the throughput of the continuously operating presses.
  • both the upper run of the upper endless belt and the lower run of the lower endless belt each with at least one casing provided with at least one suction pipe, wherein are arranged a plurality of flame burners.
  • These flame burners are gas burners, each of which directly heats a portion of the run of the belt, the waste or exhaust gases from the burners being led away in such a way that these gases impinge upon the endless belt also outside the area directly heated by the gas burners.
  • Heating the areas to be heated by gas in this way is not only much cheaper than electrical or steam heating but is also more effective because the waste or exhaust gas obtained is also used for heating the areas to be heated and namely in areas which are located in front of or behind the flame burners.
  • the conduction of the exhaust gas in the casing a good insulation of the endless belts against cooling is obtained.
  • each gas burner comprises a chamber provided at the top with slots and surrounded by a cooling jacket wherein is arranged a supply pipe with a plurality of openings for a gas air mixture.
  • a cooling air chamber construction associated with the individual gas burners limits or prevents the danger that the burners would be extinguished at the relatively high temperatures of about 600C.
  • the gas burners preferably are located parallel to one another and extend transverse to the direction of movement of the endless belts. If, for reasons of space, the casing cannot be designed so that it envelops part of the endless belt so that in practice the casing is covered by the endless belt from above, than an adequate utilization of the exhaust gas heat is still achieved although part of the waste gases are led away below the parallel gas burners.
  • the casing should be designed in such a way that it envelops at least a part of an endless belt and the part of the latter is constructed as a partition optionally with associated sealing means.
  • the corresponding endless belt is acted upon and thereby heated from one side by both the flames of the gas burners and the waste gases removed and on the other side is heated by the waste gases removed.
  • the walls of the casing be arranged spacedly from the portion of the endless belt and to provide sealing means between the side walls of the casing and the portion of the belt which extend to just before the terminal surfaces of the casing, the suction pipe being arranged in immediate proximity of the upper side of the casing.
  • the length of the casing can be made much larger than the width of the endless belt area upon which the gas burners act when viewed in the direction of movement of the belt.
  • the present invention further contemplates that the temperature of the heated plates be measured and the result of the measurements be used via a limit value circuit for switching on and off the burner or burners.
  • a contact plate is provided behind the outlet point of the casing nearest to a deflecting or reversing pulley for a respective endless belt which is pivotally mounted about a horizontal axis and is displaceable perpendicular to the plane of the plate.
  • This contact plate has at least one heat sensor which is connected to a thermometer.
  • some of the burners, and on reaching a still higher predetermined temperature, further or all of the burners are disconnected or shut down. Also, on reduction of the detected temperature in the contact plate, part or all of the burners are connected up again. It is preferred to provide at least two burners in each casing to facilitate the above-discussed temperature control and optimize heating.
  • a housing which forms a plurality of zig-zag channels and has partitions to which can be supplied the exhaust gases of the flame burner or burners heating one of the endless belts.
  • a more uniform temperature of the upper run of the lower endless steel band can be obtained according to the present invention by providing that the waste gas supply connections discharge into the partial chambers of the housing associated with the endless steel band which is located nearest to the enveloped endless belt.
  • each partition arranged in the housing can be provided at one of its ends with openings such as holes or slots, it is preferred that the length of each partition be made smaller than the width of the casing because thereby a saving in material and construction time is obtained. In both cases it preferably should be ensured that the waste gases are led through the partial cham bers in a zig-zag manner.

  • FIG. 10 is a plan view of a portion of the upper run of the lower endless steel band with a housing arranged thereunder cut at the level of the plane fixed by the axes of the waste gas feed and discharge connections.
  • the continuously operating press shown comprises two frames 1 and 2, from each of which an endless plate chain 3 and 4 is arranged in such a way that the facing chain runs 5 and 6 of said plate chains form a gap therebetween which serves to shape a stream of chips 21.
  • These plate chains 3 and 4 are each envel oped by a further respective endless band 7 or 8.
  • These bands 7 and 8 are interposed between the plate chains and the supply of chips 21 so as to directly compress the chips.
  • Endless band 8 also serves as a supply conveyor belt to supply the stream of chip material to be compressed.
  • the second left-hand guide roller or drum or the like provided for deflecting the endless band 8 is not shown in the drawing.
  • deflect or reverse plate chains 3 and 4 use is made of respective deflection pul leys 13 and 14 or 15 and 16 having a polyangular outer contour and which are freely rotatable about shafts 9 and 10 or 11 and 12 which are horizontal and parallel to one another.
  • Driving means are used to appropriately drive said chains and bands.
  • the facing chain runs 5 and 6 are influenced by feed rollers 17 insofar as they are associated with the upper plate chain 3.
  • Corresponding feed rollers 18 are associated with the lower plate chain 4 which rollers 18 face the upper feed rollers 17.
  • Feed i.e. a to 17d are influenced by hydraulic means in such a way that they bring about a compression of the chip material sheet supplied. The pressure on these rollers 17a to 17d exerted is resilient and adjustable for appropriately sequentially compressing the chips.
  • Feed rollers 18 arranged below feed rollers 17, 17a to 17d are fixedly mounted. The diameters of the feed rollers shown are such that at all times at least two adjacent feed rollers are in working connection with one chain plate 19 or 20; i. e. the length of each chain plate 19 or 20 is at least equal to double the axial spacing of respective adjacent feed rollers 17 or 18.
  • the runs or travel path of plate chains 3 and 4 remote from the chip material sheet 21 to be compressed are heated by gas burners, to be described hereinafter, arranged in respective casings 22 and 22' and/or 23 and 23'.
  • the endless steel bands 7 and 8 enveloping plate chains 3 and 4 are also heated by the waste gases of the gas burners as explained below. These bands may also be heated by electrically heated heating plates 24 and 25 which give off their heat by contact.
  • Casing 23' shown schematically in FIG. 2 and associated with the lower run of the lower plate chain 4 is divided by partition 26 into two superimposed separate chambers 27 and 28.
  • In the upper chamber 27 are arranged four gas burners 29 extending parallel to one another and transverse to the direction of movement of plate chain 4 so that their flames pass over the complete width of the chain plate.
  • the endless steel band 8 can also be passed through this chamber. If the band 8 passes through chamber 23, the partition 26 would be formed or replaced by the steel band 8 and steel band 8 would be arranged and sealed in a manner similar to the manner as shown in FIG. 3 for the casing and burners associated with the upper run of the upper plate chain 3.
  • Casing 23' is substantially longer than the combined width of the four gas burners 29, as is shown by separating lines in FIG. 2.
  • Partition 26 therefore extends to positions close to the ends 30 and 31 of casing 23 so that the superimposed chambers 27 and 28 are only interconnected or intereommunicated with one another in the area of the ends 30 and 31 of the casing.
  • the width of the partition corresponds to the space between the two side walls of the casing so that the side edges of the partition are tightly connected with the side walls of the casing.
  • Casing 22' (FIG. 3) also has gas burners 29 which are also arranged in such a way that their flames act on the underside of the upper run of the upper plate chain 3.
  • casing 22' in the same way as casing 22 envelops a portion of the plate chain 3.
  • plate chain 3 is provided in the form of a partition which via sealing means 35 is sealed relative to the side walls of casing 22 the exhaust gases produced by the burners 29 are partially removed by suction in proximity to one end wall 30' and partially in proximity to the other end wall 31 from the lower chamber 28' into the upper chamber 27' and from there via a suction pipe 32' which is located in immediate proximity of the upper side of casing 22'. This can be seen in FIG. 4.
  • Each of the gas burners 29 comprise chambers 37 provided with slots 36 wherein is arranged a feed pipe 39 for the gas air mixture having a plurality of openings 38.
  • the slots 36 are designed in such a way that in each of the hollow members 40 of chamber casing 41 is provided a rectangular bar 42 which is fixed in the hollow members via a wire 43 which envelops the bar in a spiral manner so that between bar and spiral coils of wire 43 slots 36 are formed.
  • the chamber casing 41 and therefore each gas burner is surrounded as completely as possible by a cooling jacket 44 which is in the present case formed by a type of box 45. Cooling air is passed through the box for example by suction at 46. Gas is supplied via a pipe 47 and air via a pipe 48 to feed pipe 39.
  • FIG. 7 shows how the gas burners 29 are switched on and off.
  • a contact plate 49 provided with a temperature sensor which is therefore located behind the outlet point of the casing containing the respective burners 29 (said casing not being shown in FIG. 7).

  • all the gas burners 29 provided are switched on and their flames heat the plate chain 3. If, as assumed here, the temperature of 200C is exceeded then two of the burners 29 are automatically disconnected. lf also the temperature of 210C is exceeded then the other two burners which are still burning are also disconnected. The switching on of the two last disconnected burners is brought about automatically when the temperature drops below 210C and the two other burners when the temperature drops below 200C.
  • the temperature of the plate chains can be controlled with relatively simple means.
  • Heating of one of the endless steel bands is explained relative to FIGS. 8 to 10.
  • the two endless chain belts 3 and 4 are each enveloped by an endless steel band 7 or 8 whereof the lower endless steel band 8 has a greater length than the upper endless steel band 7 because it serves to supply the chip material sheet 21 to the press. Quite apart from the fact that a longer endless steel band cools more rapidly than a shorter endless steel band it must in certain circumstances be cooled by supplying a cooling agent to prevent a too early setting of the binder supplied to the chip material. However this endless steel band in the working zone of the continuously operating press must be adequately hot to ensure setting in this working zone.
