Definitions

  • the invention relates to a water lance blower for cleaning heat exchangers, in particular a combustion chamber wall in steam boilers, the mouth of which is pivotally mounted in the combustion chamber wall of the steam boiler and is pivotally suspended at its rear part.
  • the cleaning of the fireboxes of high-performance steam boilers during operation is also carried out, among other things, with the help of water lance blowers, which emit a bundled water jet through the firebox on the opposite wall.
  • the blow pipe which has a blow nozzle in the center, is connected in an articulated manner via a roller guide to a drive which performs superimposed movements.
  • the water lance blower is moved up to an open hatch or the blow pipe is inserted into the combustion chamber through a piece of pipe stored in the hatch.
  • the water lance blower is swung out after the cyclical cleaning process or retracted linearly backwards. This requires complex mechanics that are prone to failure, which also makes automation of the cleaning process very difficult. In addition, these solutions require multiple redirections of the water supply system, which are associated with high pressure losses. In order to avoid the entry of false air into the steam boiler and contamination from the steam boiler, the pipe leadthrough the combustion chamber wall must be as tight as possible.
  • a water lance blower is also already known in which the blow pipe no longer has to be moved axially, the diameter of the pipe leadthrough through the hatch is reduced and a self-cleaning effect is achieved between the sliding parts of the pipe leadthrough (DD 235 102).
  • this is achieved in that a blow-through cylinder is rigidly flanged to the blow nozzle at the front and the mouth of the blow nozzle is inserted into the blow-by cylinder, the blow-through cylinder is rigidly fixed in the ball joint formed from a ball segment and is slotted in its free part or provided with bores.
  • a disadvantage of this water lance blower is that the effect of the ball joint with regard to self-cleaning has not occurred sufficiently.
  • the invention has for its object to form a water lance blower, which is pivotally mounted with its mouth in the combustion chamber wall of the steam boiler and pivotally suspended at its rear end, so that there is movement in the plane on all sides without contamination and the occurring Beam on the opposite wall of the boiler describes a precisely defined path.
  • a flange is provided on the mouth of the blowpipe in the combustion chamber wall, which flange is fastened in the combustion chamber wall by means of a gimbal, the rear part of the blowpipe is arranged in a guide which is vertically displaceable on a vertical spindle, the vertical spindle being horizontally displaceable at the top and bottom of a horizontal spindle and the guide being formed from a housing which is not rotatably seated on the vertical spindle and carries a fork-shaped receptacle on the side, in the transverse axis of which a cage is rotatably arranged, which receives in its inner part a sleeve rotatably arranged in the longitudinal axis of the fork-shaped receptacle, in which the blowpipe is mounted so as to be axially displaceable.
  • the vertical spindle is surrounded by a fixed protective tube with a longitudinal groove, a threaded nut with a feather key is arranged on the vertical spindle, the feather key being guided in the longitudinal groove and projecting from this a socket on which the housing sits.
  • the vertical spindle is driven by a gear motor.
  • the housing and the receptacle are advantageously formed from one part and the feather key is T-shaped, attached with its flange to the outside of the housing and guided with the shaft through the housing into the threaded nut.
  • the vertical and horizontal spindles are surrounded by a bellows or a spiral protection spring. Both horizontal spindles are supported at their ends in a front and rear box, the upper spindle is driven by a gear motor and the lower spindle is connected to the upper spindle by a chain in the rear box.
  • the water lance blower consists essentially of a blow pipe 1, a gimbal 3, a guide 5, a vertical spindle 6 and two horizontal spindles 7; 8.
  • the blow pipe 1 sits flush with its mouth in a flange which is fastened via a gimbal 3 in a manner known per se via several bolts in a hatch of the combustion chamber wall 4. There are two bolts in two different axes, so that the parts of the gimbal 3 can move in the two desired planes.
  • the rear part of the blow pipe 1 is seated in the guide 5, which is arranged on the vertical spindle 6 so as to be vertically displaceable.
  • the vertical spindle 6 is mounted on top of the horizontal spindle 7 and below on the horizontal spindle 8 and can be displaced horizontally thereon.
  • the vertical spindle 6 is driven by a geared motor 20.
  • the guide 5 consists of a housing 9 which is not rotatably seated on the vertical spindle 6 and on the side carries a fork-shaped receptacle 10 in which a gimbal-shaped cage 11 is arranged.
  • the cage 11 is formed in its inner part as a sleeve 12 and receives the blow tube 1 axially displaceably therein.
  • 12 bushings 21 are provided at both ends of the sleeve.
  • the vertical spindle 6 is surrounded by a fixed protective tube 22 which is provided with a longitudinal groove.
  • a threaded nut 23 with a feather key 2 is arranged on the spindle 6.
  • the feather key 2 is guided in the longitudinal groove, protrudes out of this and receives a socket 13 on which the housing 9 sits.
  • the vertical spindle 6 is surrounded by a bellows or a spiral protective spring 14.
  • the horizontal spindles 7; 8 are also surrounded by a bellows or a spiral protection spring 14. Both horizontal spindles 7; 8 are at their ends in a box 18; 19 stored.
  • the upper horizontal spindle 7 is driven by a geared motor 17.
  • the lower spindle 8 is connected to the upper spindle 7 by a chain in the rear box 19.
  • the housing 9 and the receptacle 10 are advantageously formed from one part, in particular from a cast part.
  • the feather key 2 is T-shaped and with its flange 24 is screwed onto the housing 9 from the outside. With the shaft 25, the feather key 2 is guided through the housing 9 into the threaded nut 23 (FIG. 6).
  • the previous protective tube 22 serves as a guide 5 for the parallel key 2 actuated by the threaded nut 23.
  • the bushing 13 which has been continuous so far is divided into two and is only inserted into the housing 9 at both ends.
  • the feather key 2 which wears during the course of the movement and must be replaced at larger intervals, can be replaced more easily.
  • the screwing of the flange 24 to the housing 9 only has to be loosened, the key 2 removed and replaced with a new one.
  • the water lance blower works as follows:
  • the blow pipe 1 is pivoted by actuating the vertical spindle 6 with the aid of the geared motor 20 and the horizontal spindles 7; 8 by means of the geared motor 17.
  • the guide 5 executes a meandering movement with the blowpipe 1, which in the same way is mirrored by the water jet on the opposite combustion chamber wall. Due to the non-rotatable housing 9, the fulcrum of the blowpipe 1 is always in the plane of travel of the vertical spindle 6, but the blowpipe 1 can carry out all the necessary movements by being mounted in the gimbal-shaped cage 11.
  • the blowing figure mathematically determined for the different combustion chamber surfaces for their cleaning can be converted into a directional movement sequence and can also be executed exactly. This eliminates the need to correct the practically executed blow figure.
  • the area of application of the water lance blower according to the invention is significantly increased.
