Definitions
- the invention relates to a convection oven according to the preamble of patent claim 1.
- Convection ovens for drying and / or melting, briefly for the treatment of guided through the oven material webs, in particular textile material webs comprise a housing in which transport means are arranged for passing a material web. Above and below the transport means nozzle boxes are mounted parallel to each other transversely to the transport direction, at the opposite, the transport means facing side surfaces nozzles are formed. Air is blown onto the material web with the nozzles. The nozzle boxes are arranged in a closed outflow space, from which the air emerging from the nozzles is sucked off and - heated and compressed - is again supplied to a pressure chamber in order to be blown through the nozzles onto the material web again.
- a device for nonwoven bonding with hot air is known.
- either hot air can be blown from bottom to top or from top to bottom through a fleece. It is possible to change the direction of air flow in sections.
- a device for guiding freshly coated leaves is known. These are acted upon both from above and from below simultaneously or from above with air and below with suction air over the entire length of the drying device.
- a device for heat treatment of a web by means of a convertible airflow is known. In this device, air can be blown from side by side arranged transversely to the material web transport direction nozzle boxes optionally from top to bottom, from bottom to top of the web.
- the EP 0062854 shows a method and an apparatus for guiding strip-like material, in which the width of the blowing nozzles is adjustable. From the DE 43 31 496 Furthermore, a nozzle system is known, in which from lying transversely to the transport direction of the web nozzle boxes air can be blown onto the web. Sliders can be used to set the width of the nozzles that are active. An object of the present invention is therefore to provide a recirculating oven, which allows a controlled inflow and outflow of process air to the material web and away from this according to essentially arbitrary criteria.
- a connection of the nozzle chambers and the nozzle boxes can be provided either with a suction chamber or a pressure chamber to pass targeted by the nozzle air flowing through the web and sucked through the sucking nozzles.
- a suction chamber or a pressure chamber to pass targeted by the nozzle air flowing through the web and sucked through the sucking nozzles.
- an optimum flow through the material web with process air can be achieved.
- the air can be distributed transversely to the material web, when the nozzle boxes are alternately arranged in mirror image.
- the convection oven also makes it possible to adjust the volume of air supplied to each nozzle box along the passage of the material through the convection oven in terms of volume and change.
- the air quantity adjustment and adjustment can be adapted very quickly to the conditions.
- the air flow can be greatly simplified and, for example, in the transport direction of the web on the one hand air in excess pressure and on the other side air in the negative pressure.
- the circulating air oven can be modular, namely by the air-carrying, laterally arranged boxes are constructed regardless of the length of the nozzle boxes arranged therebetween.
- FIG. 1 represented from the EP-A1 148 113 known construction of a convection oven 1 comprises an insulated housing 3, the interior of which is divided into a pressure chamber 5, a return flow 7 and a heating chamber 8.
- the boiler room 8 is connected via a filter element 11 in connection with the return flow 7.
- a fan 15 for example an axial fan installed.
- the pressure chamber 5 may be connected to a heating element, a cooling element and / or a dryer.
- the remindströmraum 7 comprises at least one transport means 17, preferably a guided around a plurality of guide rollers 19 circulating conveyor belt 21.
- the conveyor belt 21 is made of an air-permeable material, such as a gauze, a net or a grid made of metal or plastic and is driven by a motor M.
- a second transport means 17 ' may also be arranged above the first one, such that two runs 23 and 23' run parallel to one another and a material web 27 is guided therebetween.
- the distance between these two runs 23, 23 ' is preferably adjustable to the thickness of the material web 25 guided therebetween.
- the material web 25 is guided by the two transport means 17 in the direction of the arrow T through the circulating air oven 1.
- the nozzle boxes 27 extend at right angles to the transport direction T of the material web 27 over its entire width, ie they extend over the width of the conveyor belt 21 Nozzle boxes 27, ie at the material web 25 facing side surfaces, nozzles 29 are admitted for the passage of air.
- the nozzle boxes 27 have a cross-section narrowing from the air inlet side 31.
- a pressure flap 35 is articulated, with which the opening cross section 37 to the pressure chamber 5 is completely or partially closed (see also FIG. 2 ).
- This known arrangement makes it possible to direct warm air into the nozzle boxes 27 and from there onto the material web 25 from the air inlet side 31 from the pressure chamber 5.
- the impinging on the web 25 air escapes uncontrolled side of the nozzle boxes 27 and can pass through the spaces between the adjacent nozzle boxes 27 in the remindströmraum 7.
- the nozzle boxes 27 are shown cubic, ie also rectangular in vertical section.
- the supply of air pressure-side opening 85
- the extraction of air takes place on the right side through an opening 87 in a suction chamber 39, which is also over the length of the convection oven 1 extends.
- the suction chamber 39 and the pressure chamber 5 are connected to each other via blowers as in the previous examples.
- This embodiment of the nozzle boxes 27 results in a very balanced air distribution across the material web and regardless of the prevailing in the nozzle boxes 27 flow direction of the air.
- FIG. 9 to 11 shown embodiment of the convection oven 1 shows next to the nozzle boxes 27 arranged one above the other the passage space 77 for the material web 25.
- Inside the nozzle boxes 27 are horizontal swivel axes A, which are preferably mounted in at least one of the side walls 27 'and 27 ", is mounted on each swivel axis A, which divides the interior of the nozzle box 27 substantially diagonally into two wedge-shaped halves of space A extending edges 81 of Umschaltklappe 79 are preferably at a distance to the end walls of the nozzle boxes on the lower and upper side walls 27 ', 27 "at.
- the switchover flap 79 does not pass exactly diagonally through the nozzle box 27 to allow the flap 79 to move from the one diagonal (FIG. FIG. 9 below) to the other diagonal ( FIG. 10 below), without touching the end walls.
- the pivoting can be done with a mounted on the suction or pressure end of the Umschaltklappe 79 handle 83.
- a closing flap 89 is preferably articulated, which is guided by a guide element 91.
- the upper nozzle box 17 is connected to the pressure chamber 5.
- the Umschaltklappe 79 rests with its one edge 81 at the top left and with the other edge at the bottom right of the nozzle box 17.
- the Umsetzklappe 79 allows the entry of air from the pressure chamber 5 through the adjoining the pressure chamber 5 opening 85 in the nozzle box 27 and from there through the nozzles 29 to the material web 25.
- the suction chamber 39 is well connected to the upper half of the nozzle box 27, but because of the Umsetzklappe 79 no connection to the nozzles 29th By pivoting the Umschaltklappe 79 in the in FIG. 10 shown below, the suction chamber 39 is now connected to the nozzles 29.
- Each of the nozzle boxes 27 can be switched on either the suction chamber 39 or the pressure chamber 5 individually.
- Both the pressure chamber 5 and the suction chamber 39 is connected to a plurality of nozzle boxes 27.
- nozzle boxes 27 are used with a corresponding length L. It can consequently for differently long nozzle boxes 27 always identically formed pressure chambers 5 and suction chambers 39 are used, which consequently allow a modular production of the circulating air ovens 1.
- the convection oven 1, as in the FIGS. 3 to 8 is shown, in addition to the pressure chamber 5 and the gearströmraum 7 comprises a suction chamber 39. This may extend adjacent to the pressure chamber 5 and / or be penetrated by the nozzle boxes 27.
- the suction chamber 39 is in direct communication with the heating chamber 8.
- a passage opening 41 between the suction chamber 39 and the heating chamber 8 is covered by a filter element.
- the passage 43 can be completely or partially closed by a slider 45.
- suction valves 49 are arranged in the connecting space 47 of the suction chamber, which allow the suction of air with the nozzles 29.
- the air duct according to a convection oven FIG. 3 does not differ from that in the known circulating air oven when the suction-side closure means, such as suction valves 49, closed and the slider 45 is open to the suction side of the fan 15. Then namely the air flows from the nozzles 29 of the nozzle boxes 27 on the material web 25 and from there uncontrolled between the adjacent nozzle boxes 27 through into the return flow chamber 7 and further through the filter 11 into the heating chamber. 8
- the warm air flows from the upper nozzle boxes 27 of the nozzles 29 through the web 25 and is sucked by the present in the lower nozzle boxes 27 vacuum from the nozzles 29 or vice versa. Consequently, the warm air not only contacts the upper side of the material web 25, but it is sucked through the material web 25 and comes into contact with all parts of the material web 25 and, as a side effect, the air is filtered, ie any fibers and fluff possibly detached from the surface remain in the web 25, so that only a small number of fibers or lint can pass through the suction chamber 39 to the filter 11. So that no air can escape laterally and leave the direction of flow directed perpendicular to the material web 25, nozzle beds 30 are formed between the nozzles 29. These form surfaces lying parallel to the material web 25 between the nozzles 29.
- the feed of the material web 25 by the transport means 17 causes in the web 25 a continuous change of the air flow direction.
- an extremely uniform flow of the material web 25 with warm air over the entire thickness of the material web 25 can be achieved.
- FIG. 6 schematically shows a further advantageous embodiment of the invention.
- the nozzle boxes 27 are connected by a line 51 to a multi-way valve 53 and a returnable cap, with which either a connection to a pressure line P or a suction line S can be produced.
- the pressure line P is connected to a fan V, which is on the suction side in connection with the suction line S.
- a filter F, a suction fan S and / or a heater H or a refrigerator C can be used.
- FIG. 6 only two nozzle boxes 27, which are opposite to each other, representative of a plurality of nozzle boxes 27 are shown.
- the nozzle boxes 27 are covered in this embodiment by the front side mounted shuttering 59, so that the processing space 61 between the Nozzle boxes 27, through which the material web 25 is guided, is closed. Also, the space between the individual pairwise opposed nozzle boxes 27 may be closed by appropriate formwork or it may be the nozzle boxes 27 strung together without mutual spacing. An insulating layer 63 prevents the heat exchange with the environment. In this embodiment, the air flow can be adjusted over or through the material web from pressure box to pressure box 27. The exiting from the pressure boxes 27 with pressure air is sucked through the slots connected to the suction pressure chambers 27. An uncontrolled, exiting between the pressure boxes airflow is thereby eliminated. This arrangement allows, in contrast to the above-described, an optimal access to the material web 25th
- this arrangement allows both the supply of hot air and cold or possibly humidified air. Furthermore, the sucked back air can be cleaned in a filter F. To increase the vacuum, in particular when connecting a filter F, the pressure fan V can be supported by a suction fan S.
- the switching of the multi-way valves 53 can be manual or when using Electromagnetically controllable valves are made by the machine control. Depending on the design of the valves 53, the inflowed / extracted air quantity can also be controlled in each individual pressure box 27.
- the air outlet cross sections of the nozzles 29 can be adjusted. This makes it possible, for example-at the beginning of the heat treatment of the web 25 to supply a small amount of hot air and successively increase this amount, be it now until the end of the passage or only over a certain range and then by reducing the cross-sections to reduce the amount again.
- a suitable air quantity control can also by an arrangement according to the FIGS. 6 and 7 be obtained.
- a particularly advantageous embodiment of a closure means cap is shown.
- This comprises a flexurally elastic sheet metal or plastic band, in short band 71, which is displaceably guided in guides 73 arranged laterally on the nozzle boxes 27.
- the band 71 can be moved from a closed position, in which the passage for air between the nozzle box 27 and the pressure (5) and the suction chamber (7) is closed, in an open position or intermediate position, which the passage completely or to the desired extent releases.
- the displacement of the belt 71 is preferably done by hand.
- a tab 75 is formed at one end of the tape.
- the belt 71 is held in the guides 73 self-locking and can therefore be brought into any desired position and held there without further technical measures. An eletromechanical shift is also possible.
- the circulating air oven 1 or the various freely selectable options to supply or remove air gives the user a means in the hand to adapt the course of the heat treatment exactly to the material to be dried or treated.
- the inventive convection oven 1 proves to be particularly advantageous if the material web 25 is pressed together within the housing 3 during the heat treatment by the nozzle boxes 27 or printing plates arranged thereon, the spacing of the opposing nozzle boxes 27 and / or printing plates attached thereto Material web (25) is adjustable and adjustable.
- the juxtaposed pressure boxes 27 are switched alternately for an air passage from top to bottom or bottom to top, so provided appropriate nozzles 29, the transported in the transport direction T web 25 are vibrated. An additional vibration or vibration device for loosening the material web 25 can be omitted.
