Definitions
- the present invention relates to an installation of convective radiative heat treatment of a strip continues according to the preamble of claim 1.
- a beautiful installation is known from EP-A- 0 291 832
- the infrared radiant elements have a power density (power per unit area) very high, which allows for treatment thermal, by means of a space installation relatively small.
- Hot air heating systems have the disadvantage of having a power density much weaker than those using elements infrared heaters, their size is therefore very important compared to that of a radiant system infrared performing the same heat treatment.
- this type of installation does not require no auxiliary means to support the strip; this function being ensured by the air which can also create ripples on the tape to increase its rigidity in the direction perpendicular to its travel.
- the object of the present invention is to remedy to the disadvantages of the above techniques, by creating a installation for drying a continuous strip which has a reduced size, which delivers a high density of heating power and which provides a solution for support the continuous tape.
- the invention thus relates to an installation of heat treatment of a continuously moving belt next to infrared radiant elements and elements air blowers on this tape.
- this installation is characterized in that it comprises a succession blowers separated from each other by at minus one infrared radiant element, each element blowing comprising on each side an element suction extending near a radiant element infrared.
- the installation according to the invention thus combines infrared radiant elements with elements blowers and aspirants.
- blowing elements allow to support contactless tape, without the use of means auxiliary, while creating undulations on the strip ensuring its mechanical rigidity in the direction perpendicular to the scroll.
- blower-suction modules are such that they do not disturb the operation of infrared radiant elements.
- the blowers are separated from each other by two parallel rows of infrared radiant elements.
- each blowing element comprises near the strip at least one air blowing slot, transverse to the direction of travel Of the band.
- the preferred version of the invention as that illustrated in figure 1 concerns an installation for the heat treatment of a strip 1 which can be move at a speed that can reach or exceed 2000 m / min.
- the installation of heat treatment includes a succession of elements blowers 2 separated from each other by at least one infrared radiant element 3.
- Each blowing element 2 includes a suction element on each side 4 extending near an infrared radiant element 3.
- the radiant surface of the radiant elements 3 extends parallel to strip 1.
- blowing elements 2 and the elements aspirants 4 are made up of boxes substantially parallelepipedal extending vertically and across the width of the strip.
- the blowing elements 2 are connected to means (not shown) for creating an overpressure of air.
- the suction elements 4 are connected to means (not shown) for creating a depression.
- the elements blowers 2 are separated from each other by two parallel rows of infrared radiant elements 3.
- Each blower element 2 includes near the strip at least one and preferably two slots air supply 8, (see Figure 2), transverse by relative to the direction of movement D of the strip 1.
- each suction element includes near the band 1 a suction mouth 9, forming an acute dihedral with the adjacent end wall 10 of the blowing element 2.
- the distance between the bottom of the dihedral and the band 1 is between 5 and 50 mm, in the preferred version this distance is between 10 and 25 mm.
- edge 11 of the suction mouth 9 closest to strip 1 is connected to the wall side 12 of the suction element 4 by a wall broken 13.
- elements infrared radiant 3 and blowing elements 2 and applicants 4 are located on each side of the strip 1.
- elements 3, 2 and 4 are arranged symmetrically on either side of strip 1.
- the elements 3, 2 and 4 located on one side of the strip 1 are offset, in the direction of movement D of the strip 1, relative to elements 3, 2, 4 located on the other side of band 1.
- This offset is such that the elements 3 infrared radiant heaters located on one side are arranged opposite the blowing elements 2 and aspirants 4 located on the other side.
- This staggered arrangement has the effect of create undulations on strip 1 which stiffen it mechanically in the direction perpendicular to the scroll.
- infrared radiant elements 3 and / or blowing 2 and suction elements 4 may vary along the direction D of movement of band 1.
- the strip 1 to be treated scrolls continuously in the direction D between the two superimposed series of elements 3, 4, 2.
- Air blown by the blowers 2 (see arrows F in figure 2) hold the strip 1 away from successive elements 3, 4, 2 and supports thus the strip during its journey through the installation, without auxiliary support devices.
- the infrared radiant elements 3 presenting high power density, transfer energy to band 1.
- each blowing element 2 suck through their suction mouth 9, the combustion gases emitted by the radiant elements 3, if they operate on gas, the water vapor emitted by the strip 1 if it is dried (see arrows F 1 in FIG. 2) and the air coming from the blowing elements 2 (see arrows F 2 ).
- side opposite to the radiant elements 3 of the reflectors can be arranged to improve efficiency thermal system.
- these reflectors are arranged alternately with blowing elements, so to support the paper.
- these reflectors can also serve as suction elements.
- these reflectors can be-placed between elements blowers and aspirants.
- the arrangement of the elements radiant, blowers and aspirants can be such that it provides a non-straight path from the bandaged.
