Definitions

  • the invention relates to a dryer for perforated ceramic moldings, preferably perforated bricks, with einbringbaren, successive and possibly juxtaposed stackable dry goods carriers having provided with supporting elements storage locations for supporting the mold, wherein dry air is directed directed against the perforated surface of the moldings.
  • the invention also relates to a method for drying perforated ceramic moldings, which are deposited on storage locations of stackable dry material carriers in a dryer.
  • EP 89 408 B1 already discloses a device for venting provided with air channels dry matter in a tunnel dryer, in which only a single layer of brick blanks is arranged in the dryer. But here too complex deflection devices are needed to dry the bricks. The stocking of the dryer is extremely low for the circulation of the dry air is required per dried brick very much energy.
  • the invention has for its object to further develop a dryer for perforated ceramic moldings and a method for drying perforated ceramic moldings so that in a very large stocking uniform drying with low energy consumption per dried brick is achieved.
  • each dry-material carrier has at least one row of filing points and each filing row of support elements for at least two moldings, wherein the dry-material carrier parallel to the filing-row row arranged on both sides, frontally opposite each closed air ducts and wherein the respective one air duct with its open End connected to the dry air supply and the second air duct is connected with its open end with the air discharge.
  • each dry load carrier at least two substantially mutually parallel rows of storage locations and between the filing rows arranged shipsleitkanäle, said disposed between the filing rows air ducts are divided by vertically arranged separating elements in two on each side opposite closed air ducts and the each a sub-channel to the dry air supply is connected and the respective second sub-channel is connected to the air discharge.
  • each dry goods carrier can carry a large number of moldings, no series of moldings takes place.
  • Each dry goods carrier has its own air ducts over which the dry air is directed against the perforated end faces of the moldings.
  • no expensive louvers must be provided in the dryer itself.
  • a very large stocking in the dryer is possible and each mold is flowed through by the dry air of the same nature, so that all moldings dry the same time at the same time.
  • the advantage is that the filing system rows are each closed on the face side. This ensures that only the openings of the channels air can absorb the dry air fan out. Transverse air over the moldings is prevented by the closed end faces of the shelf rows.
  • a particularly simple structure results when the separating elements bisect the air duct diagonally. This ensures that always enough and therefore the same dry air can be passed to all bricks and also the humidified air can be discharged according to the same. In addition, due to the diagonal arrangement of the separating elements, a higher stability results and the least amount of material is guaranteed.
  • each storage place row closed at least on one side nozzle walls having bulkheads to the air duct ensures that in the air duct a corresponding back pressure can occur, so that the moldings can all be supplied with the same dry air via the nozzles.
  • the number of nozzles should correspond at least to the number of holes of the moldings to be dried. Preferably, however, the number of nozzles should be higher than that of the holes of the moldings to be dried, in order to ensure that the end faces of the moldings, in the region of which there are no holes, are accordingly exposed to dry air.
  • the bulkhead is designed as a perforated plate.
  • the holes of the perforated plate form the simplest forms of nozzles, so that the creation of the bulkhead is very cost-effective.
  • the holes of the perforated plates are aligned at least on the perforations having front sides of the moldings, it is ensured that each molding is applied over the entire surface with dry air. It is advantageous, however, if the surface of the holes is larger than the end face of the moldings, so that even on the sides in the area of the supports and above and laterally of the moldings drying air can stroke along.
  • the dry goods carrier is closed at least on the underside. This ensures that the flow in the litter stock actually takes place essentially through the moldings to be dried and not additionally in the dryer from bottom to top through the dry material carrier.
  • the support elements on which the moldings are placed are aligned substantially at right angles to the air duct ensures that the support elements of the dry air barely oppose a resistance. This optimal drying of the bottom of the moldings is possible.
  • Fig. 1 Of the Fig. 1 is to remove a dryer 1, in which a dryer car 2 is arranged, which carries a number of dry material carriers 3. Above the upper dry goods carrier 3 ', a fan 4 can be seen, over the dry air, a flow direction A is issued. At predetermined time intervals or eg after measuring the moisture differences in the moldings 5 on the dry material carriers 3, the fan 4 can reverse the flow direction, so that then the flow direction according to arrow B in the dryer 1 prevails.
  • Fig. 2 shows a dry material carrier 3, the support elements 8, which represent the storage location for the moldings 5.
  • the moldings 5 have right and left holes 9, 9 ', which are connected to each other via tubes 10.
  • the number of moldings in a row is adjusted according to the size of the dryer.
  • Between the filing rows 11 Vietnameseleitkanäle 12 are arranged, which are divided into two by diagonal separating elements 13.
  • the filing-row 11 are separated from the air ducts 12 by perforated plates 14.
  • the perforated plates 14 cause that in the air ducts 12, in which the dry air is injected, a back pressure arises, which in turn ensures the most uniform possible loading of the moldings 5 with dry air.
  • At the two outer ends of the dry material carrier only one shipsleitteilkanal 12 a, 12 b is provided in each case.
  • Fig. It can be seen that a large stocking with moldings 5 is possible by the invention, arranged in the dry material carriers 3 Vietnameseleitkanälen 12, and that in the dryer 1 itself no complex structures for an air duct are necessary, so that the dryer 1 without More can be used for other tasks.
