Definitions
- the invention relates to a method and an apparatus for drying ceramic moldings during manufacture of lattice stones, so-called perforated bricks, whereby Drying air in gaps between neighboring moldings is blown and flows through molding channels.
- Such a method and a corresponding device are already known from DE-AS 21 09 071.
- the moldings are continuously guided past nozzles, which offset each other alternately to both Sides and / or above and below the conveyor tracks in Direction of movement of the moldings at a distance from each other are arranged, which is at least twice the distance from successive moldings.
- the moldings are arranged on ropes in such a way that their channels (holes) run with the longitudinal axis in the transport direction (see Fig. 1).
- the mold transport is regulated in such a way that the moldings only about 0.5 seconds from about 20 mm wide nozzles immediately to be flown, and that there is a pause from approx. 5 sec.
- the invention has for its object an improved Method and an improved device for quick drying of lattice-like ceramic moldings, in particular so-called Perforated brick moldings to create, in which an even one with little device and energy expenditure and intensive flow around and through the moldings given and the flow at a relatively high speed is feasible.
- the invention enables a simple manner uniform and intensive flow around and flow through all moldings to be dried.
- the location of the respective molding within the trim (covering) has no negative Effect on drying, i.e. there are no delays in the drying progress due to the position of the individual Moldings in the trim / covering.
- the single-layer Form rows across the entire width of the trimmings directly as well equal (the moldings of a row become the same treated) and blown into the gaps between two rows of moldings due to the blown air opposing baffle - that of the at least in closed / hole-free transport pad in this area is formed - a dynamic pressure builds up, which ultimately leads to a advantageous underflow of the moldings and also a Air deflection for better flow through the moldings is guaranteed. Because of absolutely the same treatment of each brick shape as it passes through the dryer an optimal drying result is guaranteed.
- the direct blowing or blowing on at least one row of moldings as well as the dynamic pressure formation before it in one Blowing station allow a targeted flow through all Shaped articles with a speed not previously achieved in tunnel dryers - of over 1.0 m / sec., in particular even of about 2.0 m / sec. - and cause a largely gentle Fast drying with relatively little energy consumption.
- the "targeted" blowing makes additional guidance devices and / or reversing devices for generating air flows superfluous in opposite directions.
- the transverse arrangement of the nozzle boxes and their wide jet nozzle (s) enables a simple tunnel dryer construction, economical Utilization of space and a molding arrangement with in Channels / perforated axes running in the direction of transport.
- blowing on the front of the a row of moldings and simultaneous blowing of the back another row of moldings results in one of the Blowing station solely by its directed air jet or through their directed air jets, i.e. without using one Reversing device, caused strong air flow in opposite Directions.
- the inventive method is in a tunnel dryer realized.
- This tunnel dryer has a number 1 in general Dry channel / tunnel, through the transport documents 2 be moved in cycles.
- the transport documents can be used as Carriages or other moveable platforms. Their width can be over 5 m.
- the arrow T indicates the preferred direction of transport, the opposite in particular for air flow through the tunnel, the so-called “Longitudinal flow” runs.
- Shaped carrier 3 running transversely to the transport direction T. provided which receive molded articles 4 arranged in one layer.
- the moldings 4 lined up in transverse rows are at a distance arranged to every neighboring molding and thus on all sides air flow.
- Your channels 5 extend with the channel axis in the longitudinal direction of the tunnel dryer, i.e. in the direction of transport T and thereby enable an advantageous flow due to the "pull-through" effect of the "longitudinal flow”.
- the blank carrier 3 - and also the blank 4 of each transverse row - Are with the formation of a transverse gap 6 Spaced one behind the other. These gaps 6 each form a gap for targeted blowing in accordingly the respective requirements of assembled dry air.
- the moldings 4 have one within a row of moldings much smaller distance to the adjacent molding 4 than the distance between rows of moldings is great. Through the small side gap between side by side arranged moldings 4 is a space-saving Alignment and still an advantageous air passage guaranteed.
- the molded carrier 3 are designed to allow air to flow through. Thereby can in each blowing station 7 that of a nozzle box 8, 9 or 10 by means of a wide jet nozzle 11 in a wide, air jet extending across the entire width of the trim (Wide jet) 12 (see FIG. 1) or 13, 14 (see FIG. 2) or 15, 16 (see FIG. 3) blown out and against the as Baffle acting transport pad 2 blown dry air also flow under the blown / sprayed molding 4 and also partially coat / rinse the underside with the dry air.
- Wide jet trim
- Each molding carrier 3 has a stiffened (stabilized) Carrier profile made of sheet steel, whose profile (cross section) is designed in the manner of an upside down "U”.
- the length of the U-bridge corresponds approximately to the length of the molded part in this dimension (see Fig. 1-3). This makes a large area and good support of the "green" moldings 4 is guaranteed. To achieve an advantageous stability, the U-section widens downwards. In preferred In this way, the lateral legs are symmetrical Trapezoid.
- the U-web and the two U-legs of the molding carrier 3 are perforated, the proportion of holes in the respective surface is about 35-65%.
- the hole portion of the U-bridge is as possible large, but depending on the material of the to be dried moldings 3 executed such that for the drying molding 4 sufficient support is provided and adverse impressions are avoided.
- the holes in the as Set-up elements / spacers acting side walls each molding carrier 3 is designed such that before the same a back pressure, preferably from 20 to 100 Pa. can build - in a particularly preferred and advantageous manner the hole percentage here is approximately 50%.
- the tunnel dryer in drying tunnel 1 several blowing stations arranged one behind the other 7 available, which work according to Figures 1, 2 or 3.
- the transport documents 2 are each blowing station 7 fed and shut down in such a way that the air jet 12 or the air jets 13-16 each in one Target gap 6 between two transverse rows of moldings can be blown in.
- the molding is transported in cycles around the Interval of a row so that the moldings 4 "row around Row "are blown.
- Each air jet 12-16 is with the entire width blown out at the same flow rate. If one Blowing station 7 works with two air jets, lying the same one behind the other and the corresponding slot nozzles run parallel in the transverse direction of the tunnel dryer.
- Fig. 2 generally discloses the arrangement of two in parallel extending wide jet nozzles 11 on a nozzle box 9.
- the air jets 13, 14 are preferred in FIG. 2 obliquely against the perforated end faces (cut surfaces) of all Moldings 4 of a transverse row of moldings (Transverse row) directed.
- the inclined air jets 13, 14 are in particular in this way on the molding / molding cross section aligned that the whole face / face the moldings 4 are blown - it meets the height Center axis (bisector) of the moldings 4 and the respective Air jets 13/14 (and in Fig. 3: 15/16) together.
- the nozzle box 10 is included provided two wide-jet nozzles 11 at an angle to one another, which air jets 15, 16 diverging downwards blow on two rows of moldings, one side being the front and on the other hand blow the back of a row of moldings becomes.
- the two wide jet nozzles 11 of the nozzle box 10 are symmetrical arranged to the center of the nozzle box / vertical.
- the jet center plane closes with the nozzle box center level or vertical one opening downwards An angle of 15-25 °, preferably approximately 20 °.
- the invention is characterized by a method and a Device for drying air carriers through which moldings can flow 3-ply and possibly also in wide transverse rows - With hole axes running in the transport direction T. 5 - arranged moldings (perforated bricks) 4, whereby the drying air by means of a transverse jet nozzle (s) 11 in gaps 6 between rows of moldings except for the transport pad 2 and the whole Trimming width is blown equally intensely and everyone Mold 4 flows around and flows through and from the outside and inside dries evenly.
- each slot nozzle in the gap width and / or slot position adjustable / adjustable can have a wide jet nozzle numbered 11 telescopically trained and / or arranged (not shown) lips.
