Definitions

  • the invention relates to a method for drying green roof tiles, the same in one Drying room in a single-layer arrangement inclined from the vertical are dried on moldings and a plant for carrying out the process.
  • a drying installation is known from De 34 25 625 A1, in the case of clay roof tiles or Similar products are stored on pluggable frames, which in turn are inclined Position inserted in the frame carrier. In addition to better use of drying room should result in a more favorable drying behavior. About the way of air flow and thus the drying medium is not exposed to the medium causing the drying disclosed.
  • This previously known version appears to be a chamber dryer act - cf. Fig. 1 and 2, from which it can be seen that on the side walls angle profiles are arranged on which the support units rest.
  • Such a dryer version for roof tiles to be dried, so-called. green roof top is for quick drying hardly suitable.
  • the invention has for its object a method and an installation for carrying it out of the process, with which quick and easy drying of roof tiles is possible can be carried out with simple means and is largely as a result distortion-free roof tile moldings are achieved and made available for the fire.
  • the invention becomes greener in a plant for drying fresh roof tile moldings
  • Roof tiles 1 realized that a tunnel dryer 2 and a large number of times through the same movable roof tiles to be dried on air carriers that can be flowed through by air 3 has transporting carriage or sledge-like transport frames 4.
  • you tunnel dryer 2 ventilated in counterflow i.e. its longitudinal flow L runs counter to the direction of transport T (see FIGS. 1 and 2 and FIGS. 5 and 6).
  • the tunnel dryer 2 there are several to one another in the tunnel dryer 2 spaced, which can be supplied with drying air conditioned according to the requirements Blowing stations 5 available. Part of the longitudinal flow is sucked in and after Blended with hot air back into the drying duct towards the material to be dried.
  • Each blowing station 5 has at least one and one running transversely to the transport direction T. inclined in the height direction, i.e. vertical air inclined from the vertical (Blowing air flow) 6 blowing nozzle or nozzle arrangement, by means of which through the covering to be dried is blown (see FIGS. 1, 3 and 4).
  • each blowing station 5 is designed such that there is a multichannel outflow with one behind the other and across Transport direction T extends wide beams.
  • Each blowing station 5 has a nozzle box 5a, in the bottom of which a plurality of wide, one behind the other slot nozzles 5b is provided. However, it can also many individual nozzles, lined up in a transverse row, to achieve a so-called "Broad jet” see.
  • the nozzle box air supply is preferably carried out by means of a wide flow fan 5c.
  • the individual blowing stations 5 are in the Tunnel width is not continuous, but only extends over a section, in particular, about half the cross-sectional half of the tunnel dryer 2 and are also alternately arranged on the left and right side so that a meandering or streamlining air flow (see. Fig. 2 and 5).
  • the blank carrier 3 are in Direction of transport T seen in front of the roof tiles 1.
  • the one between the back of the roof tiles (Roof tile underside) and the horizontal included angle can be about 50 to 85 ° be.
  • only one row of moldings is shown in the vertical direction, can also two rows of moldings (with appropriate training and / or arrangement of the mold carriers 3) arranged and thus double the amount of roof tiles can be dried at the same time. Due to the longer flow path in the case of a two-strand molding arrangement, at a longer drying time may be useful for certain clay materials - so that despite double Occupancy is not always double dryer performance achievable.
  • the molded carriers 3 are for receiving one Roof tile group formed in a row arrangement. You can do one or two whole Take transverse row (s) of roof tiles running transversely to transport direction T or just over extend a portion of the tunnel width. It is particularly preferred if on the Channel width of the tunnel dryer 2, two molding carriers 3 are arranged side by side. These each enable a single-row or two-row molding arrangement Blank supports 3 have the same for each green roof tile 1 to be dried Form-fitting support and air-flowable reception area.
  • the individual molded carriers 3 are preferably on the so-called transport frames Dryer car, on or on holding arms 4a at a distance from a closed, Airflow deflecting surface, esp. Floor plate 4b, arranged / held.
  • the individual green roof tiles 1 are supported with their underside in places on the Shaped carriers 3 and with a front edge, preferably the head end, on one Abutment 3a from.
  • the air is blown out of the blowing stations 5 by means of oblique air jets, as indicated in principle in FIG. 1 and from FIG. 3 can be seen.
  • the blow-out angle of the individual air streams 6 is dependent on the Roof tiles inclined and made by appropriate nozzle box slats causes (see Fig. 3).
  • These nozzle box fins can be fixed or in the housing changeable (adjustable).
  • the transport racks 4 are in relation to the Nozzle boxes 5a stopped in such a way that out of the slot nozzles 5b each row of roof tiles running transversely to the transport direction T from the one above The end of the molding is flowed from both sides. This will make it intense and gentle Mold blowing guaranteed.
  • the mold carriers 3 partially blown shaded roof tiles undersides and thus upper and Underside dried with approximately the same intensity.
  • the green roof tile to be dried 1 undergoes the same treatment on both main surfaces, making it a one-sided, prevents more drying. Due to the equal treatment of both sides of the roof tile Prevents warping due to drying.
  • the blowing direction of the individual air streams 6 runs preferably at a small angle, in particular about 5 - 15 °, to the sloping roof support level. As a result, the inflow to the rear is stronger.
  • At least one longitudinal alley 7 is present in the roof tile covering on the transport frames 4, in each of which an end of the nozzle box facing the center of the tunnel dryer cross section arranged screen 8 for lateral limitation of the longitudinal flow L and meandering or meandering circulating air.
  • This screen 8 extends in Longitudinal tunnel dryer approximately over the area of the nozzle box air outlet section and extends in the height direction to about the lower end of the roof tile.
  • the invention is characterized by advantageous operation of the dryer system and simple Structure of the same.
