Definitions

  • the invention relates to a water lance blower for cleaning heat exchangers, in particular a combustion chamber heating surface in steam boilers, the mouth of which is pivotally mounted in the wall of the steam boiler and is pivotally suspended at its rear part.
  • 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 carries out 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.
  • these solutions require multiple redirections of the water supply system, which are associated with high pressure losses.
  • 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.
  • the invention has for its object to provide a water lance blower, which is pivotally mounted with its mouth in the wall of the steam boiler and is 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 at the mouth of the blowpipe which is attached to a segment of a universal joint and the universal joint is fastened in the combustion chamber wall
  • the rear part of the blowpipe is arranged in a guide which is vertically displaceable on a vertical spindle is, the vertical spindle above and below is horizontally displaceable on a horizontal spindle and the guide is formed from a housing that does not rotate on the vertical spindle and carries a fork-shaped receptacle on the side, in which a gimbal-shaped cage is arranged , which is formed in its inner part as a sleeve and receives the blow tube axially displaceable therein.
  • 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 formed, 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.
  • FIG. 1 shows a front view of the water lance blower
  • FIG. 2 a side view according to FIG. 1
  • Fig. 5 another variant of the guide for the blow pipe in a partial section
  • the water lance blower consists essentially of a blow pipe 1, a universal joint 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 attached to a segment of the universal joint 3.
  • the universal joint 3 is fastened in a hatch of the combustion chamber wall 4 by means of several bolts.
  • 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 on top of the horizontal spindle
  • 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 cardan-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 displaceable 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.
  • Both 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 screw connection 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 center of rotation of the blowpipe 1 is always in the plane of movement 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 area of application of the water lance blower according to the invention is significantly increased.

Abstract

Une tuyère d'injection d'eau utile pour nettoyer des surfaces de transfert de chaleur, notamment la surface de chauffe de la chambre de combustion de chaudières à vapeur, a une embouchure montée pivotante dans la paroi de la chaudière et une partie postérieure suspendue pivotante. Pour que la tuyère d'injection d'eau puisse se déplacer dans tous les sens sur un plan au niveau de l'embouchure, sans se salir, et pour que le jet incident sur la paroi opposée de la chaudière décrive une trajectoire définie avec précision, une bride placée sur l'embouchure du tuyau de soufflage (1) est montée sur un segment d'un joint universel (3) et le joint universel (3) est assujetti dans la paroi (4) de la chambre de combustion. La partie postérieure du tuyau de soufflage (1) est placée dans un guidage (5) monté sur une broche verticale (6) et horizontalement mobile en haut et en bas sur des broches horizontales (7, 8). Le guidage (5) est constitué d'un boîtier (9) non rotatif qui repose sur la broche verticale (6) et qui porte sur le côté un logement (10) bifurqué dans lequel est située une cage (11) en forme de joint de cardan. La cage (11) a une partie intérieure en forme de manchon (12) et y reçoit le tuyau de soufflage (1) de manière axialement mobile.
