Definitions

  • Such tunnel dryers composed in fact of two superimposed tunnels, are known and used in the manufacture of construction products such as bricks or tiles.
  • tunnels have a production capacity depending on the number of places available in the nacelle inside the tunnels for the products to be dried. This means that for the same length of tunnel, the capacity is limited by the number of nacelles that can equip the conveyor chain. However, the nacelles must respect a given interval between two successive nacelles so that, at the level of the corner references constituted by a pulley, between the exit (or the entry) of a tunnel and the well of descent / rise, two successive nacelles do not collide.
  • a tunnel dryer comprising the features of the preamble of claim 1 is disclosed in the document FR 2517417 ,
  • the present invention aims to develop a tunnel dryer with a larger production capacity for otherwise identical dimensions or allowing a reduction of the dimensions of the dryer for the same capacity as that of known facilities.
  • the invention also proposes to create means for improving the capacity of existing dryers.
  • the present invention relates to a tunnel dryer of the type defined above characterized in that at each corner of the rectangular path, at the well, the return pulley at the end of the horizontal path is complemented by a deflection pulley installed in the well so that the chain passing around the deflection pulley and the diverting pulley follows an inclined path substantially corresponding to the hypotenuse of the triangle constituted by the rectangle whose vertical side is equal to the height of the nacelle to its point of suspension to the chain and the horizontal side is equal to the half-width of the nacelle.
  • the dryer according to the invention allows a very significant increase in capacity of the order of 15 or even 25% by better occupation of the chain with closer nacelles without creating risk of collision of two successive nacelles at the level of a bevel gear.
  • the nacelle comprises a single solid partition to close the airlock of a well connecting the two tunnels.
  • the airlock can be closed at the top and bottom only by the presence of a low or high full partition of two successive nacelles since they are sufficiently close together to ensure this seal.
  • the deflection pulley and the deflection pulley are completed by an auxiliary pulley, creating an outward deflection of the chain circulation path which would pass only on the return pulleys and the deflection pulleys. , to sufficiently separate the deflection pulleys from the well to create an airlock closed by one or two successive nacelles.
  • the invention also relates to a dryer comprising, for one of the tunnels, at the junction of the wells, a return pulley and a deflection pulley and, for the other tunnel, at each end, a return pulley combined with a deflection pulley and supplemented by an auxiliary pulley creating the outward deviation of the chain circulation path.
  • the invention in its various characteristics, allows not only the realization and the first installation of tunnel dryers with reduced space between the nacelles but also the transformation of existing tunnel dryers to seriously increase the production capacity.
  • a tunnel dryer (s) 1 for drying construction products such as bricks or tiles consists of two horizontal tunnels, a lower tunnel and an upper tunnel, opening at each of their two ends 11, 12; 21, 22 in a vertical shaft 30, 40.
  • the tunnels 10, 20 and the wells 30, 40 are traversed by a chain conveyor 50 passing over four return pulleys 51, 52, 53, 54 at each junction between a tunnel 10 , And a well 30, 40, both at the descent into the well and at the bottom end of the well as well as up a well to the entrance in the upper tunnel 20.
  • the chain conveyor or to simplify the chain 50 is equipped with nacelles 55 or swing in which one loads the products to be dried. These nacelles 55 are spaced a minimum distance (d) so as to make the best use of the space available in the dryer (1) to optimize the efficiency.
  • the distance (d, d1) separating two nacelles 55 or their attachment points 56 to the chain 50 is limited to a minimum of because of the problem of collision between two successive nacelles at the junction of a tunnel and a well, when the nacelle 55 upstream, down in the well and the downstream nacelle comes from the tunnel, which is also true for a traffic in opposite.
  • the loading / unloading of the nacelles is done in one of the wells 40 equipped with a loading / unloading station 60.
  • the loading station 60 comprises, in the passage 61 followed by the nacelles 55, a double opening 62, 63 on either side, to access both sides of a nacelle stopped in this position.
  • the loading / unloading of the products are two operations that are done almost simultaneously.
  • the loading device not shown, pushes the products placed on a floor of the nacelle through for example the opening 62 and at the same time, deposits green products, that is to say products to be dried, in through the opening 63.
  • This nacelle loading technique known per se, does not require a more detailed description.
  • the nacelles provide a certain degree of tightness in order to prevent excessive outside air being sucked in by the vacuum cleaner 74 of the chimney 75.
  • the description refers to a chain 50 driving the pods 55
  • this chain is actually doubled and the pods 55 are attached to the parallel chains 50 which follow the path described above.
  • the chains 50 pass on the return pulleys 51-54 which may be toothed pulleys or chain wheels, at least some of which drive the chains.
  • the pulley 54 is a driving pulley.
  • the nacelles 55 are attached to the chains 50 in the upper part substantially in their middle 56 for reasons of balance and in practice, the attachment points are located slightly below the top of the nacelle.
  • the sides of the nacelles are equipped with unrepresented rollers which circulate in lateral rails to the passage of the nacelles in the lower tunnel 10 and in the upper tunnel 20.
  • the nacelles 55 are only hanging on the chains 50.
  • the dryer 1 whose structure is described above, is traversed by the boats 55 which circulate in a certain direction (arrow F) and by hot drying gases circulating against the current (arrow G).
  • Hot gases are provided by equipment 70 consisting of burners and fans that blow hot gases into the lower tunnel 10 near its exit.
  • the hot gases pass through the lower tunnel 10 to exit through a bypass 71 equipped with a vacuum cleaner 72 and bypassing the vertical descent shaft 30 to be injected again in the upper part of the well at the upper tunnel 20 in which the gases also flow against the current.
  • the hot gases circulating in the upper tunnel 20 can be partly recovered at point 73, near the entrance 21 of the tunnel to be recycled through the equipment generating the hot air 70. But the main part of the hot gases, charged humidity, is evacuated by the chimney 75 equipped with a vacuum cleaner 74.
  • the branch 71 is equipped with a fan 72 so as to blow the hot gases coming from the lower tunnel 10 into the outlet 22 of the upper tunnel 20. But to prevent the hot gases thus blown into the upper tunnel 20 from attempting to pass through the well 30 to circulate in a loop, the well comprises an airlock 31 closed by the nacelles 55.
  • This airlock 31 is formed by a cylinder 32 of rectangular section corresponding to the section of the nacelle 55 (width and depth, the depth is the dimension of the nacelle perpendicular to the plane of the figure 1 ).
  • This cylinder 32 is closed on the sides. Its height is such that at least the bottom wall 551 of a nacelle and the upper wall 55S of the following nacelle are in the cylinder 32, in the closed parts around the entire periphery.
  • each known nacelle has an upper wall 55S and a lower wall 551 constituted by a solid plate so that whatever the movement of the nacelles 55 in the cylinder 32, there will always be an upper wall 55S and a lower wall 551 belonging to the same nacelle or two successive nacelles, which will plug this cylinder 32.
  • the Figure 2A schematically shows the operation of the conveyor 50 carrying the n boats, at the junction between a horizontal tunnel 10, 20 and a vertical shaft 30, 40 for example the upper left corner of the installation of the figure 1 .
  • the return pulley 51-54 has a zero diameter; it is represented by the point T2.
  • the efficiency of the tunnel dryer 1 depending inter alia on the speed of circulation of the pods 55 in the tunnels and also the interval between two pods 55, we must bring the pods (or swing) as much as possible while avoiding the collision between two successive nacelles at the level of a reference angle between the horizontal direction and the vertical direction as presented to the Figure 2A .
  • specific references to the Figure 2A or then the Figure 2B ) were used; thus the nacelle carries the reference N.
  • the path of the conveyor chain 50 driving the nacelles N is represented by the path T0, T1, T2, T3, T4 corresponding to the characteristic points of the path.
  • the horizontal path T0, T1, T2 joins the vertical path T2, T3, T4 of the chain at the pulley T2 which is of zero radius in this example of principle.
  • the nacelle N has a rectangular shape of vertices A, B, C, D; it is attached to the middle M of its upper side AB to the chain 50.

  • the first position N1 of the nacelle is that of the end of its horizontal path in the tunnel, when the nacelle begins to penetrate into the vertical well continuing to flow in the horizontal direction to its position N2.
  • the position N1 of the nacelle is defined by the points A1, B1, C1, D1 of the vertices.

  • the Figure 2B positioned in relation to the Figure 2A shows the path of the chain at an angle gear according to the invention.
  • the trajectory of the chain conveyor 50 is defined by the points T0, T1, T5, T6 and the characteristic positions of nacelles N11, N3, N4 as well as an intermediate position N 11-3 between the positions N11, N3.
  • the vertices A, B, C, D of the nacelle are not all referenced in the different positions to avoid cluttering the drawing.
  • the path of the conveyor T0, T1, T5, T6 according to the invention differs from the path T0, T1, T2, T3, T4 of the known installation according to the Figure 2A in that the path portion T1, T2, T3 is replaced by the diagonal T1, T5 which makes it possible to reduce the minimum spacing between two successive nacelles to avoid their collision at the PC angle feed.

  • the position N4 shows the nacelle which precedes the nacelle at the position N3, at the minimum distance defined according to the invention.
  • the theoretical minimum distance between the attachment points of two successive nacelles is equal to the sum of the width of the half-nacelle and the length of the diagonal of a half-nacelle.
  • a simple numerical calculation shows that reducing the interval between successive nacelles can represent a gain of the order of 30 or even 40%, which is considerable.
