Definitions

  • the invention relates to a device for uniform Loading a flat surface of a workpiece, in particular the end face of a band bundle, with a heat treatment gas, which in the preamble of Claim 1 specified genus.
  • Such a device as for the high temperature zone a grate cooler, especially for cement clinker, is to be used, for example, from DE-OS 24 54 202 and has a flat nozzle bottom and several punctiform openings in the bottom of the nozzle on the single, discrete gas jets on the plane Straighten the surface of the workpiece; the openings are according to a given pattern on straight lines arranged in the nozzle base, so that each row of holes a forms slit-shaped nozzle opening.
  • a grate plate for a clinker cooler is known, in its surface Openings for the passage of cooling air open out.
  • the surface of the grate plate is between the openings with guiding surfaces for the Bulk clinker provided, which is thereby distributed on the grate plate so that their Surface is evenly tempered.
  • GB-A-12548 A.D 1911 also describes a spray device for a mixture Compressed air / paint with a spray head, which contains the features of the preamble of claim 1, and its strip-shaped outlet area through three superimposed and pressed plates is formed. In the big areas the plates have passage channels in different directions, so that from the outlet openings, which are located on the end face of the block thus formed, Exit beams in different directions.
  • the new blowing system is therefore particularly suitable for convective heat transfer on the end faces of coils, their arrangement to the blowing system not from is determined in advance and from batch to batch can change. So the new blowing system has it Advantages of from German patent specification 35 03 089 known device, but without the disadvantages, namely the need for some centering of the blowing system on the coil end faces to be heated in To have to buy.
  • Another extremely beneficial application for the device according to the invention is the production of a high heat transfer to small parts, such as B. ball bearing rings, that on one surface, essentially one flat layer with a fluid, e.g. B. a cooling gas, to be charged.
  • a fluid e.g. B. a cooling gas
  • Such a device has the Advantage of the special orientation of the ball bearing rings no requirements were placed on the nozzle system become. It is sufficient for. B., the rings on an appropriate Roll under the blowing device past move.
  • the four are designed as bores circular nozzle openings 1, 2, 3, 4 combined to form a nozzle opening group 5.
  • the adjacent nozzle openings 1-4 of a group 5 have one another smaller distance than from the nearest nozzle opening 1-4 one neighboring group.
  • the nozzle base 6 is a flat sheet. Several such groups 5 of nozzle openings 1 up to 4 form the entirety of the nozzle openings in the nozzle base.
  • the Deflection devices 7 consist of a cross section of the deflected jet considered, U-shaped sheets, i.e. channel-like guide elements, with the joining surface 10 created by the inclined section on which the nozzle openings containing planar nozzle bottom 6 are placed. Through the corresponding sloping section the desired deflection angle is between 15 ° and 45 °, as in the example illustrated case, as mentioned, 45 °.
  • the projection of the deflected nozzle jets forms an example and according to the invention in case shown for two adjacent nozzle openings divided by 360 ° the number four of the nozzle openings equal 90 °.
  • the devices 7 are for Jet deflection on the downstream side of the nozzle openings 1 to 4. As an alternative for this purpose, they can also be arranged on the inflow side.
  • the distance between the closest nozzle openings 1-4 adjacent Nozzle opening groups 5 is at least 1.5 times the smallest distance between the nearest nozzle openings 1-4 in a group 5.
  • the geometrically free nozzle surface in the projection makes it flat Nozzle plate 6 or the reference plane of the nozzle plate 6 between 2% and 10% of the associated total area of the nozzle base 6 or its reference plane.
