For example, there is known one in which an injection nozzle for injecting cleaning water is capable of swinging and reciprocating (see Patent Document 1).

JP 2001-87676 A

  However, in many conventional apparatuses, the spray nozzle itself is a fixed type, and the cleaning range is limited because the direction and object of cleaning and the area are restricted. And since the range which can be covered with one apparatus is limited, the installation location had to be many. In addition, it takes time to install and install the apparatus, and the installation work is complicated.

  In view of such circumstances, an object of the present invention is to provide a fluid jet reaction force rotary cleaning device having high cleaning efficiency and excellent handleability.

  The fluid ejection reaction force rotary cleaning device of the present invention includes a rotating body having a plurality of ejection nozzles for ejecting fluid, and a base body that is connected to and supported by a pipe and rotatably supports the rotating body. The fluid is supplied to an inner chamber formed between an outer peripheral portion of the base shaft body and an inner peripheral portion of the rotating body, and the fluid is radially supplied to a fluid feeding path of the rotating body communicating with the inner chamber. And the rotating body is rotated by a reaction force of the fluid ejected from the ejection nozzle.

  Further, in the fluid jet reaction force rotary cleaning device of the present invention, the rotating body is rotatably supported around the base shaft body via bearings spaced in the longitudinal direction of the base shaft body, The inner chamber is disposed so as to be sandwiched between the bearings.

  Further, in the fluid jet reaction force rotary cleaning device of the present invention, the inner surface of the flange portion that contacts the thrust direction end surface of the bearing has slit-like grooves formed in a substantially radial or radial direction.

  In the fluid jet reaction force rotary cleaning device of the present invention, a slit-like groove is further provided on the outer peripheral portion of the base shaft body.

  According to the present invention, the fluid is pumped from the pipe through the base shaft to the fluid feed path of the rotator, so that the rotator is rotated by the reaction force of the fluid ejected from the ejection nozzle, so that a wide cleaning object is extremely efficient. Can be cleaned well. In this case, an inner chamber is formed between the outer peripheral portion of the base shaft body and the inner peripheral portion of the rotating body, and the fluid is pumped in the radial direction to the fluid feeding path of the rotating body communicating with the inner chamber. Thereby, it is possible to substantially suppress the thrust load from being generated on the rotating body by the water pressure, and to rotate the rotating body smoothly and efficiently.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a preferred embodiment of a fluid jet reaction force rotating cleaning device according to the invention will be described with reference to the drawings.
FIG. 1 shows an example of the overall configuration of a fluid jet reaction force rotary cleaning device of the present invention. The fluid jet reaction force rotary cleaning device 10 includes a rotary body 12 having a plurality of jet nozzles 11 for jetting fluid, a base shaft body 13 connected to and supported by a pipe 100 and rotatably supporting the rotary body 12. The rotating body 12 is rotated by the reaction force of the fluid ejected from the ejection nozzle 11.

  In this embodiment, for example, when cleaning various industrial facilities, the fluid jet reaction force rotating cleaning device of the present invention is used. Moreover, although it is set as the example which typically injects water from the injection nozzle 11, it can apply effectively with respect to another installation or fluid as a use object or fluid of this invention apparatus.

  2 and 3 show the detailed structure of the fluid ejection reaction force rotary cleaning device 10. The rotating body 12 has a substantially cylindrical shape, and a pair of arms 14 extend in the radial direction from the outer peripheral surface at a substantially central position in the axial direction. The injection nozzle 11 is attached to the tip of each arm 14, but the ends of the arms 14 are bent so as to face in opposite directions. A blowout hole 11a is formed through the center of the injection nozzle 11, and water is sprayed from the blowout hole 11a in a spray form or the like. Typically, water is jetted from the blowout hole 11 a in the tangential direction of the rotation circumference of the jet nozzle 11.

  The arm 14 extending from the rotating body 12 is formed in a pipe shape and has a fluid feed path 15 inside. An inner chamber 16 is formed between the outer peripheral portion of the base shaft body 13 and the inner peripheral portion of the rotating body 12, and the fluid feed path 15 opens into the inner chamber 16 (opening 15a) and communicates therewith. As will be described later, water is supplied from the base shaft body 13 to the inner chamber 16, and the water is further pumped in the radial direction to the fluid feed path 15 of the rotating body 12.

  The rotating body 12 is rotatably supported around the base shaft body 13 via two bearings 17 spaced in the axial direction (thrust direction) of the base shaft body 13. The inner chamber 16 is disposed so as to be sandwiched between the bearings 17. The bearing 17 is typically formed in a ring shape from Teflon (registered trademark) or the like, and is fitted into a stepped portion 12 a formed on the inner peripheral portion of the rotating body 12. The rotating body 12 and the bearing 17 are disposed between the upper and lower flanges 18 and 19 and are held so as not to be substantially rattled.

  In this example, the upper flange 18 is configured separately from the base shaft body 13, and is fastened to the upper end portion of the base shaft body 13 by a bolt 20. The lower flange 19 is configured integrally with the base shaft body 13.

  A fluid feed path 21 communicating with the inside of the pipe 100 is formed inside the base shaft body 13. The fluid supply path 21 is formed to a position substantially the same height as the arm 14, opens to the outer peripheral portion of the base shaft body 13 (opening 21 a), and communicates with the inner chamber 16. As shown in FIG. 2, the fluid feeding path 15 of the arm 14 and the fluid feeding path 21 of the base shaft 13 are opened so as to face each other with the inner chamber 16 interposed therebetween.

  In addition, it has the thread part 13a in the lower end part of the base shaft body 13, and is screwed to the piping 100 by this thread part 13a.

  The inner surfaces of the flanges 18 and 19 that are in contact with the end face in the thrust direction of the bearing 17 have slit-like grooves formed in a generally radial or radial direction. For example, as shown in FIG. 3, grooves 22 and 23 having appropriate depths are formed from the center to the outer periphery of the flanges 18 and 19, respectively.

  Further, a slit-like groove 24 is further provided on the outer peripheral portion of the base shaft body 13. The groove 24 is formed at an appropriate depth, for example, in a spiral shape on the outer peripheral portion of the base shaft body 13, and in this case, is formed so as to be connected to the center portion side of the grooves 22 and 23 of the upper and lower flanges 18 and 19.

  In the above configuration, water is pumped from the pipe 100 to the inner chamber 16 via the fluid feed path 21 of the base shaft 13, and further from the inner chamber 16 to the injection nozzle 11 via the fluid feed path 15 of the arm 14. And water is pumped. When water is jetted from the blowout hole 11a of the jet nozzle 11, the rotating body 12, and thus the jet nozzle 11 itself, is rotated by the reaction force of the water. An annular spray S is formed from each spray nozzle 11 as shown in FIG. 1, and the spray nozzle 11 itself rotates in this way, so that a very wide cleaning target can be cleaned efficiently. Therefore, various industrial facilities and the like can be cleaned extremely efficiently and completely.

  In the above case, the thrust water pressure acts on a part of each bearing 17 facing the inner chamber 16. The thrust load due to the water pressure is received by the upper and lower fixed flanges 18 and 19, and the thrust load does not substantially act on the rotating body 12. That is, since the frictional force is not substantially generated at the contact portion with the bearing 17 and the flanges 18 and 19 at the step portion 12a and the end surface of the rotating body 12, the rotating body 12 rotates very smoothly. Moreover, since there is no frictional force, water pressure can be used efficiently.

  Further, impurities such as dust mixed in the water are discharged from the inner chamber 16 through the groove 24 of the base shaft body 13 and further from the center portion to the outer peripheral portion through the grooves 22 and 23 of the flanges 18 and 19. . In this way, during operation of the apparatus, impurities can be discharged to the outside of the apparatus in advance before reaching the injection nozzle 11, thereby preventing inadequate rotation of the rotating body 12 due to impurities or the like and clogging of the injection nozzle 11. Can do. In this respect as well, the smooth operation of the device is guaranteed.

  When the apparatus of the present invention is installed and installed, it can be easily and accurately attached by simply screwing the screw portion 13 a into the pipe 100 at the lower end of the base shaft 13. Therefore, installation and installation work are not time-consuming and installation work is easy.

The preferred embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments, and can be appropriately changed within the scope of the present invention.
For example, the number of injection nozzles 11 can be increased or decreased as necessary. That is, it may have a single injection nozzle 11 or may have three or more injection nozzles 11. In any case, water is injected from each injection nozzle 11 as in the above-described embodiment. Thus, the rotating body 12 is smoothly rotated by the reaction force of the water.
Further, the apparatus of the present invention is effectively applied to cleaning other various facilities and apparatuses. In that case, other fluids of water can be used as the fluid to be ejected.
