Definitions

  • the invention relates to a water lance blower for cleaning heat exchangers, especially a combustion chamber heating surface in steam boilers during of the company.
  • a water lance blower is already used for cleaning Heat exchangers known with the mouth of the blowpipe via a universal joint is attached in a hatch of the combustion chamber wall and in which the rear part of the blowpipe is arranged in a guide on a vertical Spindle is adjustable in height, with the vertical spindle above and is horizontally displaceable below on a horizontal spindle.
  • the horizontal spindles are stored at their ends in a box, there attached and are operatively connected on one side.
  • the guide is formed from a housing that is not rotatable on the vertical Spindle sits and carries a fork-shaped holder on the side in which a gimbal-shaped cage is arranged in its inner part with a sleeve is provided and receives the blow tube axially displaceable therein.
  • the horizontal spindles are with one with this water lance blower Surround the bellows to protect the spindles from dirt.
  • the invention has for its object a water lance blower, the front via a universal joint in a hatch of the combustion chamber wall and over the rear a guide on a vertical, top and bottom driven on a horizontal Spindles slidable spindle is arranged and in which the guide from a housing with a fork-shaped holder for a gimbal Cage exists, so that the respective position of the blowpipe recognizable during the cleaning process, a synchronous drive of the horizontal spindles constantly guaranteed and the replacement of the Dust protection on the horizontal spindles provided with little effort is to be made on site and vortex formation within the Blow jet can be avoided.
  • this is achieved in that in the hatch of the combustion chamber wall a transition box made of trapezoidal, side panels drawn inwards, forming a square box is inserted between the respective side panels touching each other within the box reinforcement plates arranged with a receiving hole are the universal joint in the mounting holes via a joint holder is attached, in the inner joint of the universal joint the mouth of the Blow-through tube is inserted and into the mouth of the blow-through tube Nozzle head with the subsequent blow pipe is screwed in, the nozzle head divided into an inflow cone and a head piece and into the cylindrical Part of the blowpipe is a swirl plate, the upper horizontal Spindle and the lower horizontal spindle via a rigid transmission shaft and an angular gear are connected to each other, the horizontal Spindles at the end are supported in ball bearings by an annular Bearing housing, which is provided with an external groove and the bearing housing with each other via a guide tube for the spindles are connected, a split wedge-shaped in the recess of the bearing housing Inserted ring and on
  • the transition box is on two opposite Provide mounting plates on both sides. Furthermore, the upper one is horizontal Spindle with the right slope direction and the lower horizontal spindle with left slope direction formed. There are bellows on the guide tubes postponed.
  • the pressure ring is provided with a conical inner surface. The angle scales are from the center outwards with an increasing angle degree marking Mistake.
  • the water lance blower consists essentially of two horizontal spindles 14; 15, a vertical spindle 30, a blowpipe 10, a transition box 1, a left spar 31, a right spar 32 and a guide 33 for the blowpipe.
  • the transition box 1 serves to fasten the mouth of the blowpipe 10 via an auxiliary frame 40 in a hatch of the combustion chamber wall.
  • the transition box 1 consists of trapezoidal, inwardly drawn, side plates 2 forming a square box 34. Between the respective touching side plates 2, reinforcing plates 3 with a receiving bore 4 are arranged inside the box 34.
  • the junction box 1 is provided on two opposite sides with mounting plates 29, with which the attachment to the subframe 40 takes place.
  • the water lance blower is set up on the combustion chamber wall in such a way that the mouth of the blowpipe 10 is located centrally in the existing hatch of the combustion chamber wall.
  • the universal joint 5 is fastened in the receiving bores 4 via a joint holder 6.
  • the mouth 8 of the blow-through tube is inserted.
  • the nozzle head 9 with the adjoining blow pipe 10 is screwed into the mouth 8 of the blow-through pipe.
  • the nozzle head 9 is divided into an inflow cone 11 and a head piece 12. This ensures better production engineering compliance with the inner nozzle head geometry to ensure the blast jet quality.
  • the swirl plate 13 required for generating a laminar flow necessary in the blowpipe 10 is arranged at the rear end of the cylindrical part of the blowpipe 10. This eliminates turbulence in the area of the nozzle head.
  • the blow pipe 10 sits with its rear part in the guide 33, which is arranged on the vertical spindle 30 so as to be vertically displaceable.
  • the vertical spindle 30 is mounted on top of the horizontal spindle 14 and below on the horizontal spindle 15 and can be displaced horizontally thereon.
  • the vertical spindle 30 is driven by a gear motor 35.
  • the horizontal spindles 14; 15 are supported at the ends in ball bearings 18 which are received by an annular bearing housing 19.
  • the bearing housings 19 are provided with an external recess into which a split wedge-shaped ring 21 is inserted.
  • the bearing housing 19 are via a guide tube 20 for the horizontal spindles 14; 15 connected together.
  • a pressure ring 22 with fastening holes 36 is pushed onto the ring 21 from the guide tube 20.
  • the pressure ring 22 is provided with a conical inner surface.
  • the horizontal spindles 14; 15 in the side rails 31; 32 braced.
  • the horizontal spindles 14; 15 are connected on one side within the spar 31 or 32 via a rigid transmission shaft 16 and angular gear 17.
  • the upper horizontal spindle 14 is provided with a right-hand pitch direction and the lower horizontal spindle 15 with a left-hand pitch direction.
  • a bellows 39 is pushed onto the guide tubes 20.
  • the upper horizontal spindle 14 is connected to a corresponding drive via a slip clutch 38.
  • To change the bellows 39 on the horizontal spindles 14; 15 are only both pressure rings 22 from the spar 31; 32 and the entire assembly can be removed from the water lance blower without disassembling it.
  • the special design of the storage for the horizontal spindles 14; 15 also enables their disassembly and assembly on site, since a relatively easy adjustment of the parallelism of the spindles 14; 15 can be made.
  • the guide 33 for the blow pipe 10 is formed from a housing which is not rotatably seated on the vertical spindle 30.
  • the housing carries a fork-shaped holder on the side, in which a gimbal-shaped cage 25 is arranged.
  • the cage 25 is formed in its inner part as a sleeve 37 and receives the blow tube 1 axially displaceably therein.
  • An angle scale 24 is arranged on the upper tab 23 of the fork-shaped holder, and a pointer 26 projecting beyond the angle scale 24 is arranged on the outside of the cage 25.
  • the angle scale 24 is provided with an increasing angle degree marking from the center outwards. The horizontal position of the blowpipe 10 during the cleaning process can thus be seen.
  • another similar angle scale 27 is arranged on the outside thereof and a plug-in notch pin 28 is inserted into the sleeve 37 in the vertical central axis of the cage 25. The vertical position of the blowpipe 10 can be seen on this angle scale 27.
