Definitions

  • the invention relates to a drying trolley for holding in drying devices acted upon with drying air moldings, in particular perforated bricks o. ⁇ . Structural bodies, wherein a plurality of moldings is halterbar on a dryer car, according to the preamble of claim 1.
  • dryer cars for holding in drying devices acted upon with drying air moldings, in particular perforated bricks o. ⁇ . Structural bodies with through recesses, known.
  • Such dryer cars are often designed shelf-like and allow the stacking of several layers of moldings on top of each other, so that an effective use of space in the drying oven can be ensured with a high throughput of Formligen.
  • a difficulty, especially with a high stocking of the dryer car, however, is to ensure a uniform drying of each individual molded article.
  • the DE 195 27 415 shows a dryer car in which moldings are also flowed through by their through-holes through drying air, so as to provide over the extent of a single molding approximately uniform drying conditions and to reduce the risk of warping.
  • this solution implies that moldings that are not at the edge of a stack are blown by such drying air that already pass through other moldings and thereby absorb moisture from them Has.
  • different drying ratios are created for each series of moldings, so that the drying times and qualities vary.
  • the invention has for its object to provide an improvement in the drying quality for the largest possible number of moldings and still be able to ensure a high stocking and good handling of the dryer car with moldings possibly also underschledrained formats.
  • drying wagon on the one hand due to the towering brackets for supporting several halved hold dry material carriers for receiving at least one layer of moldings with a variety of moldings stacked on each other, typically about 8 to 20 layers, and on the other hand, the moldings To be able to act on the uplifting and over a plurality of layers extending Beerleit Vietnamesen for deflecting drying air in the direction of the blanks with a similar over the entire stack height air flow.
  • the air handling aids are continuous over their height extent, so that no individual adjustments for individual layers must be made.
  • the height of each individual layers is not relevant for the over the entire height of the same flow; the layers can therefore vary in their height and number and be equipped with molds of different formats, so that a high degree of variability is created with minimization of conversion effort.
  • a stack can be completely inserted from above into a gap between two stacks and displaced so that the dry goods carriers are pushed onto the supports of the upright holders and a complete stack can be set up at once.
  • the top and bottom are provided with an at least almost horizontally extending end surface to form a flow channel in which the substantially horizontal inflowing air does not escape up or down and in their horizontal Flow direction can pass through channels of the moldings.
  • the moldings are respectively above and next to each other to arrange a stack in the depth of only a series of moldings stack on the dryer car, each stack of moldings each an air assist before and one downstream.
  • the recesses of the moldings are favorably extended in the vehicle longitudinal direction, so that they are optimally reached and flowed through by the deflected by the Heilleit Huawein Troeknungs Kunststoff.
  • a stack can be influenced both during drying by an air assist which is behind and behind it, for example by the fact that in the operating position the air-assisting aids are so diagonal in plan view that they extend almost over the entire width of the dryer wagon are and with a vertical edge of a back-connecting stack and with the opposite vertical edge of a forward adjacent stack directly adjacent.
  • the flow direction may vary from both sides, for example alternately in the drying device, and yet each be created a point-symmetrical geometry about a vertical axis for the entire stack, whereby from both sides equal drying conditions are formed.
  • the dry goods carriers can be formed simply and flexibly by slats which can be laid on supports provided on the holders. Not all supports have to be covered with dry goods carriers. If a number of supports is omitted, results in a double layer spacing.
  • the supports can also be adjustable in height in development of the invention.
  • the Heilleit Vietnamesen extending over a height that corresponds to the maximum stack height of moldings and jewelligen dry material carriers, so that the actual height and number of layers for the Gutleit Vietnamesen is irrelevant.
  • the dryer trolley includes a chassis and is mobile over it by a drying device.
  • the dryer car is composed of a plurality of individual shelf units linked directly to one another to form a long unit which can be loaded and unloaded in cycles and advanced through the drying unit.
  • FIG. 1 An exemplary dryer car 1 according to the invention is shown in FIG. 1 in plan view and broken off to the front and rear indicated only schematically. It is composed of a plurality of directly coupled to each other units E with here two shelves. These units E can follow each other in considerable numbers,
  • Such a dryer car 1 serves for holding in drying devices 2 acted upon by drying air moldings 3, in particular perforated bricks o. ⁇ , structural bodies with particular through recesses 5.
  • Each control unit E includes here by way of example two vertical shelves behind each other, each serving to receive a stack 4 can.
  • the blanks 3 can be arranged in the shelves in each case in mutually separated stacks 4 with a plurality of superimposed layers 4a (FIG. Fig. 4 ) are arranged on the dryer car 1, wherein a large number of such stacks 4 can be provided one behind the other on the dryer car 1.
  • the stacks 4 are arranged in the dryer carriage 1, that the here through recesses 5 of the moldings 3 are aligned along the direction of travel F of the dryer car 1 in a drying device 2.
  • Each stack 4 comprises for optimizing the air flow with respect to the direction of travel F of the dryer car 1 (depth of the stack 4) only one layer of moldings 3 before the next stack 4 follows at a distance A.
  • the dryer car 1 is provided on its shelves with upstanding supports 6 for supporting a plurality of dry goods carriers 7 which can be held on top of one another for receiving at least one layer 4a of blanks 3.
  • the holders 6 have a plurality of supports 8 distributed over their height, onto which the drying material carriers 7 can be placed.
  • the dry material carrier 7 can be formed very easily by auflegbare on the supports 8 of the brackets 6 slats. These are inexpensive and have only a low weight.
  • the supports 8 can be height adjustable. Also, the number of superposed dry material carrier 7 may vary. If, for example, each support 8 is omitted, resulting in the individual layers 4a twice the height. Likewise, it is not necessary that all supports 8 are occupied to the top. Thus, a very high variability for a variety of different forms to be dried 3 is possible.
  • the dryer car 1 is provided at a distance A between the stacks 4 with likewise upwardly projecting air guiding aids 9 for deflecting drying air in the direction of the blanks 3 over a plurality of layers 4a.
  • air-assisting aids 9 air 12, 10 laterally transversely injected by fans 12 can thus be deflected in such a way that it receives a component parallel 13 or anti-parallel 14 to the direction of travel F of the dryer car 1 and thus can flow through the longitudinal recesses 5 of the molded products 3 optimally (FIG. Fig. 1 ).
  • the air handling aids 9 are integrated in the respective units E of the dryer car 1.
  • An obliquely oriented to the direction of travel F arrangement of the individual stacks 4 and / or the fans 12 may be favorable and possible depending on the flow conditions.
  • an orientation of the air-assisting device 9 adapted to this inclination preferably takes place.
  • the air guiding aids 9 comprise upstanding guide surfaces 15 and are on the upper and lower sides with an at least almost horizontally extending end surface 16, 17 (FIG. Fig. 7 ) provided for the formation of a flow channel, wherein the end surfaces 16, 17 prevent escape of air up or down.
  • a diffuser or baffle is dispensable due to the uniform flow of the stack 4 over the entire height.
  • Each stack 4 of moldings 3 is an air assist 9 before and one downstream. This means that always a stack 4 and an air guide 9 alternately follow each other on the dryer car 1.
  • the shipsleit Vietnamesen 9 are here in each case extends over a height corresponding to the maximum stack height of moldings 3 and respective dry material carrier 7. Thus, the Heilleit Vietnamesen 9 can be used for each assembly of the stack 4 in the same way, without any conversion or adaptation measures would be required.
  • the air inflow 10, 11 from both sides can therefore be used completely equally for drying the moldings 3.
  • a particularly noteworthy feature of the invention relates to a mobility of the air handling aids 9:
  • the distances A can be released to their full extent by the air assist 9 between the in FIG. 1 shown operating position for optimized flow of the moldings with drying air and a loading position for the arrangement of moldings 3 on the dryer car 1 are movable.
  • each air guiding aid 9 is pivotable in the direction of the arrow 20 about a vertical axis in the vicinity of its edge 18 from the diagonal operating position into a loading position arranged at right angles to the drying trolley and to a stack 4.
  • FIG. 2 is the Belade ein an airlift 9 dashed lines and marked with bracketed reference numerals. Due to the fact that it rests flat on the shelf for a stack 4, the distance A In almost full width for introducing a stack 4 with dry material carriers 7 and layers 4a of moldings 3 stacked thereon can be available.
  • fuses for the operating position and / or the loading position may be provided, for example, spring-loaded fishing hooks or magnets.
  • the dryer car 1 may comprise a chassis 21 with rollers 22 and be mobile through a drying device 2.
  • the dryer car as a whole can be placed on a chassis and above it by the drying device 2 is mobile.
  • the tunnel-type drying device 2 may, for example, comprise two superimposed rows of fans 12, so as to be able to ensure a uniform air flow over a large stack height and thus be able to effectively utilize the air-laying aids 9 which are extended over the entire height.
