Definitions
- the invention relates to a dryer for strip or plate-shaped material, in particular a multi-stage dryer for plasterboard or veneers, according to the preamble of claim 1.
- a dryer with a distribution wall with semicircular air guide bodies is known, which is arranged on the air inlet side of the chambers of a chamber dryer.
- the distribution wall narrows the inflow cross-section to the chambers, thus increasing the pressure in the pressure chamber and leading to an even air distribution over the individual chambers. A uniform flow in the chambers themselves is not achieved.
- a chamber dryer is not a generic type.
- the invention is based on the dryer known from DE 197 01 426 A1, in which a uniform drying over the entire width of the material is to be achieved. This is largely achieved in that the distance between the nozzles and the crop surface is adjustable at least at one end of the nozzle box and is different in size at both ends. However, it has been shown that the drying on the side of the air inlet in the nozzle box is less than over the remaining length of the nozzle box. Studies have shown that swirling occurs in the area behind the air inlet in the nozzle box. These arise due to the compact design of the dryer, which causes a relatively high, vertically directed flow velocity in the pressure chamber in front of the nozzle boxes.
- the speed in the area of the air inlet in the nozzle box also has a vertical component, which causes the swirling. This' that total must be dried for longer in order to ensure the maximum permissible residual moisture over the entire property means in practice. This means that more energy has to be used for drying than is required under optimal conditions.
- the object of the invention is to provide a dryer with the features specified in the preamble, in which even drying on the side of the air inlet in the nozzle box is achieved with improved energy utilization.
- Figure 1 shows the cross section of a dryer according to the invention.
- Figure 2 shows a longitudinal section with a view of the partition
- Figure 3 shows a guide body according to claim 2 as a detail.
- Figure 4 shows a guide body according to claim 3 as a detail.
- the dryer is e.g. from a large number of modular compartments.
- a compartment measures 2.0 m to 2.5 m in the conveying direction and is 2.5 m to 6.0 m wide. As can be seen from FIGS. 1 and 2, it has a ceiling 1 and side walls 2, 3.
- a core area 7 is separated from a circulating air duct by an intermediate ceiling 4, a partition 5 and a grid-like support frame 6. This consists of a horizontal channel 8 above the core area 7, a lateral vertical pressure chamber 9 and a collecting channel 10 arranged essentially mirror-symmetrically on the opposite side.
- the width of the core area 7 is approximately 50 to 70% of the total width, the height approximately 60 to 80 % of total height.
- rollers 22 are arranged in several, in practice mostly four to twelve levels, which are stacked at the same distance from each other at about 250 mm to 350 mm, which are on one side on the partition 5 and on the other in the Support frame 6 are stored. All rollers 22 can be driven at the same speed via gears and chains (not shown) and form a roller conveyor on each floor, which extends over the entire length of the dryer.
- finger-like nozzle boxes 12 are arranged in the spaces between adjacent rollers, which extend across the width of the roller conveyor.
- the boundary wall of the nozzle box 12 facing the transport plane is provided with nozzle openings for inflating drying air onto the drying material 11.
- One end of the nozzle box 12 is designed as an inflow opening 13, the other end 14 is closed.
- the nozzle boxes 12 are wedge-shaped, so that their cross-section decreases steadily in the direction of the closed end 14.
- the end with the inflow opening 13 is suitably fastened in a rectangular recess in the partition 5.
- a guide body 20 is cross-section-neutral with respect to the inflow opening 13, that is to say the cross section of the inflow opening 13 is not changed.
- the length L with which a guide body 20 projects into the pressure chamber 9 is
- a fan 15 is fastened to the side wall 2 and can be driven by a motor 16.
- the suction side of the fan 15 is open to the collecting duct 10.
- the pressure side of the fan 15 is connected to a diffuser 17 which opens into the horizontal duct 8.
- a heat exchanger 18 is arranged on the 20 side of the horizontal duct 8 opposite the fan 15.
- the collecting duct 10 and the horizontal duct 8 are separated from one another by a wall 19.
- the invention can also be used in other dryers in which, due to the compact design, disturbing intermingling occurs when entering the nozzle box 25, e.g. for belt dryers.
- a meandering belt can be arranged instead of a number of transport systems.
- the problem of turbulence becomes more apparent with an increasing number of floors, that is, especially with gypsum plasterboard dryers, where up to twelve floors are known.
- a guide body 20 extends over the width of the inflow opening 13 of a nozzle box 12.
- an upper nozzle box 12 and a nozzle box 12 located immediately below are preferably connected in a pant-like manner between two adjacent transport levels, so that both form a double box and have a common inflow opening 13.
- the fan 15 sucks drying air from the collecting duct 10 and presses it through the diffuser 17 into the horizontal duct 8 in the direction of the arrow 21. At the end of this duct 8, the drying air flows through the heat exchanger 18, is heated and flows into the pressure chamber 9.
- the flow here is directed from top to bottom and must be deflected into an approximately horizontal flow when it flows into the nozzle boxes 12.
- the guide bodies projecting into the pressure chamber 9 cause the flow lines to be largely aligned, so that eddy formation is avoided.
- the drying air is blown out of the nozzles onto the surface of the material to be dried 11, absorbs water and flows into the collecting duct 10, from where it is sucked back into the circuit to the fan 15. Part of the drying air, which corresponds approximately to the amount of water evaporated, is removed from the circuit.
- the guide body 20 shown in cross section in FIG. 3 according to claim 2 is preferably used in dryers for peeled veneer. It is designed here in the manner of a finger slightly curved upwards.
- the cross section of a guide body 20 is composed of two circular segments with non-identical centers.
- the radius R1 of the upper circular segment 23 is 180 mm to 220 mm, preferably 190 mm to 210 mm; the radius R2 of the lower circular segment 24 is 80 mm to 120 mm, preferably 90 mm to 100 mm.
- a rounding with a radius of 10 mm to 15 mm is used instead of the pointed end 25.
- the guide body 26 shown in cross section in FIG. 4 according to claim 3 is preferably used in dryers for plasterboard.
- the guide body 26 here has the shape of a rectangle with an attached semicircle, the round side protruding into the pressure chamber 9.
