Definitions

  • the invention relates to a water lance blower with a water lance, which is pivotally mounted with its mouth on or in a hatch, with a drive system having at least two drive units for controlling the water lance, and with a holding device for fastening the water lance blower on a wall.
  • a water lance blower are used in particular for the purification of thermal systems, the water lance can blow a stream of water through the in-service and flowed with flames and / or flue gases heat plant on accessible from the hatch wall areas.
  • Water lances of this type are described, for example, in WO 96/38701, WO 96/38702, WO 96/38703 and WO 96/38704.
  • the water lancers give a bundled stream of water through the firebox to the opposite wall.
  • a spalling of the soot, slag and ash is effected.
  • the impact area of the jet of water generated by the water lance blower generally follows a certain predeterminable path on the surface to be cleaned, also known as a blower, this way generally meandering and optionally avoiding obstacles, openings or other sensitive zones.
  • drive systems of known water lance blowers have a horizontally oriented and a vertically oriented drive unit. At least one of the two drive units is attached with appropriate devices directly to the heat system.
  • the second drive unit of known drive systems has devices, by means of which this second drive unit can be fastened on the first drive unit in order to realize a two-axis control. In most cases, the second drive unit is arranged such that it is additionally guided, for example, to the heat installation or parts of the drive system.
  • a drive system is described for example in WO 93/12398.
  • a drive unit is usually attached to a part of a framework. This drive unit moves during operation both the other drive unit and a water lance and is made particularly robust for stability and rigidity reasons.
  • the second drive unit which is articulated in particular on the water lance, adapted to the structural design of the first drive unit. Specially designed holding and fastening devices are therefore required.
  • the individual components (such as the drive system, the water supply, the control cabinet) known Wasserlanzenbläser are further arranged around a centrally positioned water lance that they are located in areas outside the pivoting range of the water lance, so as not to limit the pivoting range.
  • the water lance is connected to a water supply line, which must follow the movements of the water lance and this may not restrict at the same time.
  • Such a water supply known water lance blower is therefore out of the swivel range immediately after leaving the water lance out. For these reasons, known water lance blowers have a much larger footprint than the actual movement of the water lance requires.
  • the object of the present invention is to provide a water lance blower of the type mentioned, the footprint substantially equal to the area below the maximum pivoting range of the water lance, which is easy to assemble and maintain and which reduces the above-mentioned logistical requirements for a company the water lance along predeterminable blow figures with different speeds is controllable.
  • the water lance blower has a water lance, which is arranged pivotably on the one hand with its mouth on or in a hatch and on the other hand connected to a water supply system.
  • the water lance can blow a jet of water through the heat exchanger, which is in operation and is supplied with flames and / or flue gases, to wall areas which can be reached from the hatch.
  • the water lance is controlled by a drive system with two drive units and thus allows the generation of any blowing patterns through the water lance.
  • the drive system of the water lance blower has two drive units, which are characterized in that they are designed as modules. This means that the drive units form functional units for themselves and as such are completely interchangeable. Such trained identical drive units in a drive system are therefore interchangeable with each other.
  • a modular embodiment of the drive units additionally reduces the logistical expenses of a company, which now only has to manufacture, store or logistically manage a reduced number of variants of the drive units. This significantly reduces the manufacturing and service costs of the company.
  • the drive system supports a compact and simple arrangement of the water lance blower.
  • the attachment of the holding device to a thermal system can thus be made in the desired position.
  • the drive units can be arranged arbitrarily, so that, optionally, with regard to components of the thermal system, the drive units are combined in such a way that a desired pivoting range of the water lance is realized.
  • the first and second drive units are arranged perpendicular to each other and connected to each other, wherein the first is connected to the holding device and the second drive unit is moved through the first.
  • the second drive unit directs the water lance so that its end area can cover a maximum projection area during operation.
  • the orientation of the L- or T-shaped arrangement is irrelevant.
  • a frame is not needed for such an arrangement.
  • Advantageously and particularly preferred is the arrangement of the integrated parts of the water supply system in the region of a corner of the projection surface of the water lance.
  • the second drive unit of the drive system is designed with a connecting element which protrudes laterally with one end from the second drive unit. With this end of the connecting element, the water lance is articulated.
  • the connecting element is to be designed so that the freedom of movement of the water lance is not limited.
  • the connecting element is arranged such that the projecting end is aligned with the side of the drive system of the water lance blower, which faces the holding device, in particular with integrated parts of the water supply system.
  • This orientation of the connecting element results in a very compact and space-saving water lance blower, since in this way the drive units and the holding device are arranged essentially on a surface which can be swung over by the rear end region of the water lance.
  • the connecting element is moved by the two drive units in one plane and thus allows the movement of the water lance. Due to the different positions of the water lance, the articulation point of the connecting element varies. Does the water lance strongly (for example both drive units are near an edge position), the point of articulation moves in the outer area of the water lance towards the flexible conduit. In an upright position the articulation point is closer to the mouth of the water lance.
  • the modular drive units each have at least one motor, a spindle and a spindle nut.
  • the motor is connected to the spindle and thus rotates during operation, the spindle, whereby the mounted on the spindle spindle nut is moved translationally.
  • Such drive units are particularly suitable for exact path control. In addition, they are characterized by their simple structure.
  • the water lance blower on a guide system with sliding shoes and rails.
  • the spindle nut is connected to the sliding shoes.
  • the shoes are guided by two parallel rails.
  • the rails are attached directly to the drive unit and aligned so that they are parallel to the spindle. In this way, the bending and torsional rigidity of the drive unit is increased.
  • the motors of the drive units can work accordingly Their purpose can be optimized and thus enable reliable path control of the spindle nut. Furthermore, these engines are characterized by a low heat generation, high speeds and the possibility of detecting the speed for determining the distances covered by a connected via a spindle spindle nut. It is particularly advantageous if, in addition to the travel control of the water lance by the motors of the drive units, the water lance is designed with a motion sensor which reports disturbances in the motion transmission.
  • the sliding shoes are connected to a fastening unit.
  • the fastening unit is connected either to the number of sliding shoes, which are moved translationally on a rail, or it is connected to the total number of sliding shoes. If the fastening unit is connected to all sliding shoes, this represents a kind of platform covering an area between the rails and fixing the spindle nut.
  • a fastening unit designed in this way significantly increases the torsional rigidity of the drive unit.
  • the fastening unit has according to a further embodiment positioning aids for the exact alignment of attachable to the fastening unit structures.
  • the fastening unit is a kind of interface to the structures which are moved by the drive unit.
  • Such structures are, for example, a further drive unit, the connecting element for fixing the water lance or components which form part of a guide on the thermal system.
  • the exact path control of the water lance along predetermined blow patterns with arbitrary speeds requires an exact alignment of these structures on the drive unit. With such positioning aids assembly errors are avoided.

  • Particularly sensitive to dirt are, for example, the motor, the spindle, the spindle nut, and the parts of a translational guide system with sliding shoes and rails. Due to the installation site, the drive system for a water lance blower is exposed to a great variety of environmental conditions. The high proportion of soot or ash in the ambient air and optionally leakage or spray water are kept away from the spindle and guide system in this way.
  • the rails of the guide system are attached on the cage-like rail.

  • the bellows is not connected to the movable fastening unit, but serves to protect during the downtime of the water lance blower. This means that at the beginning of a cleaning cycle of the water lance blower, the bellows is moved to a position in which it only extends over edge regions of the gap and is stretched again after the cleaning cycle has ended and thus covers the at least one gap up to the fastening unit.
  • This embodiment is particularly well suited in conjunction with additional sealing means at the gap, which during operation of the Water lance blower prevent the ingress of contaminants into internal areas of the drive unit.
  • At least one sliding shoe is connected in each case to a rail with a small boat.
  • the fastening unit can be fastened both between the sliding shoe and the shuttle and on the side of the shuttle which faces away from the sliding shoes.

  • Under a boat is an elongated structure to understand, which tapers at its narrow ends so that a wedge shape is formed. The boat is arranged in a gap between the rail and cover and thus protrudes beyond the cover.
  • sealing means Areas between fixed parts of the drive units, such as the rail or the cover, and the movable parts (attachment unit or boat) are executed according to a development of the drive system with sealing means. Because of the accelerations and speeds occurring during operation of the water lance blower, the sealing devices are made robust. Furthermore, the sealing means are adapted to the external environment, in this context, in particular the temperature insensitivity of the sealing device is in the foreground, since the drive system is usually attached directly to the heat system.

  • Another particularly advantageous embodiment of the water lance blower has two bands for sealing the gap of the drive unit.
  • the bands are connected to the rail and to the cover and extend over the gap to be sealed. Between these bands, the movable structure is guided. It is particularly advantageous to use an outwardly directed band of metal an inwardly directed rubber band.
  • the bands lie on each other in areas remote from the movable structure and open near the position of the movable structure. For example, the metal band provides good protection against ashes, etc., while the flexible and elastic rubber band adapts particularly well to the moving structure.
  • air with overpressure can be introduced into the rail.
  • the air escapes essentially through the gaps between the rail and the cover. Due to the air flow from inside sections of the rail to the outside, the ingress of dirt and soot from the environment of the drive system is prevented.
  • the holding device is characterized by integrated control elements for at least one drive unit or for the formation and monitoring of a water jet. These controls affect, for example, the speed of the motor or regulate the water flow blown out by the water lance.

  • This holding device has advantageously integrated into it parts of the water supply system.
  • the water lance blower By integrating parts of the water supply into areas of the water lance blower, which are arranged close to the water lance, the water lance blower is made very compact.
  • the holding device also provides a kind of adapter between a mostly rigid running water supply and a flexible, flexible forwarding of the water to the water lance out. The forwarding is moved only in a relatively small section, whereby lower forces to move the water lance are needed and the space, in which parts of the water lance blower move, is significantly reduced. It is precisely this reduction of the movement space has the consequence that in the positioning of the water lance blower according to the invention a complex adaptation of the water supply system to the structural conditions of the thermal system is no longer required.
  • the holding device has at least one connecting device for a separate water supply line having.
