Definitions

  • the invention relates to a device for hydromechanical descaling with several liquid jet nozzles, on which the to be descaled Workpiece is moved past, and with at least one Liquid pump.
  • At a defined feed rate of the workpiece can be off the workpiece length are calculated that time in which the nozzles have to radiate. About the number of nozzles and about this jet time can then be the total volume flow or the total amount of water calculate that comes out of the nozzles. The required total volume flow and determine the required pressure of the liquid the pump size and / or the number of pumps during configuration a Entzu shoresstrom.
  • the present invention is based on the object at a Device for hydromechanical descaling the number of required liquid pumps and / or their performance compared Descaling systems with annularly arranged liquid jet nozzles to be able to reduce.
  • the object is achieved with a device for hydromechanical descaling with several liquid jet nozzles to which the descaling workpiece is moved past, and with at least one Solved liquid pump, which is characterized in that the Liquid jet nozzles are arranged in one place and that the device comprises means for moving the workpiece (11) several times past the liquid jet nozzles, each time only part of the liquid jet nozzles are active.
  • the liquid jet nozzles no longer ring in a plane arranged around the workpiece and all at the same time active or not active, but they are now rather arranged or driven, that the individual surface areas of the workpiece during transport be processed one after the other at the liquid jet nozzles.
  • the total volume flow of the liquid to the individual Split points with liquid jet nozzles By this division the volume flow, the at least one liquid pump can be smaller be designed, or it can be the number of required pumps to reduce.
  • the total purchase price for the liquid pumps is So in a device according to the invention significantly lower than at known plants.
  • liquid jet nozzles In order to obtain an optimal descaling result, the liquid jet nozzles to arrange or control such that one after the other an all-round descaling of the workpiece is possible.
  • the liquid jet nozzles are preferably on bars or rings arranged, wherein the beams arranged pivotable about its longitudinal axis so that an optimal angle of impact of the liquid can be adjusted on the workpiece surface.
  • Fig. 1 shows a descaling device 10 according to the prior Technique with a total of four rings around a workpiece to be descaled 11 arranged around bars 12 to 15 with liquid jet nozzles 16, all in one plane and arranged and driven are that the workpiece 11 when passing through the annularly arranged liquid jet nozzles 16 machined on all sides becomes.
  • the workpiece 11 descaled over its entire length is a supplying the liquid jet nozzles 16, not shown here liquid pump or more such Fluid pumps switched to idle mode until the next Workpiece arrives.
  • liquid pump or more such Fluid pumps switched to idle mode until the next Workpiece arrives.
  • the device 10 according to the invention is designed so that the workpiece 11 in both directions through the liquid jet nozzles 16 is movable therethrough and with each passing of the liquid jet nozzles 16 only part of the nozzles 16 is active, so can the Total volume flow can be divided into several partial volume flows, which must be made available at a later time, so that now pumps of lower power or used in smaller numbers can be.
  • the state of the art known in the art descaling device 20 of FIG. 2 the here shown in side view, two spaced apart Make 21 and 22, at which liquid jet nozzles 23 for descaling the surface of the workpiece 11 are arranged.
  • the surface of the workpiece 11 At the Passing the workpiece 11 in the direction of arrow 24, the surface of the workpiece 11 first on the bottom and on the front descaled and then at the point 22 at the top and on the back side.
  • the two points 21 and 22 of descaling are thereby spaced by a distance D from each other, which is greater than the length L of the workpiece 11.
  • Fig. 3 shows a descaling device 30 with two liquid jet nozzles 31 provided bars 32 and 33, a descaling the top and the bottom of a workpiece 11 allow.
  • the Beams 32 and 33 are spaced by a distance D in the transport direction 34 of FIG Workpiece 11 spaced apart, which is greater than the length L of the workpiece 11.
  • the bars 32 and 33 are arranged in the same place.
  • the beams 32 and 33 are pivotable about their longitudinal axis 35, 36 arranged so that the impact angle of the liquid on the surface of the workpiece 11 is adjustable.
