Definitions

  • the present invention relates to a device for holding in position the end of a mobile element, driven in rotation in a tube by Inaction of a fluid. It also relates to the application of this device to the maintenance of a rotary member for preventing fouling and / or continuous cleaning of a fluid conduit, in particular with a view to improving heat transfers.
  • An object of the invention is therefore to propose a device for holding in position the end of a mobile element, driven in rotation in a tube taken by a fluid, which causes only a minimum increase in the loss of charge of this tube.
  • Another object of the invention is to propose a device of this type, which can be assembled and disassembled simply and in a very short time on the tubes, so as not to complicate the maintenance operations of the installations of which these tubes are part.
  • the invention also aims to propose a device of this type which can be applied to maintaining in position a rotary member for preventing fouling and / or continuous cleaning of the tubes of a heat exchanger.
  • the subject of the invention is a device for holding in position one end of a movable element driven in rotation inside a tube by the action of a fluid, characterized in that it comprises, on the one hand, a bearing member, one or more parts of generally cylindrical shape enclose the outside of one end of said tube; - on the other hand, a pin, mounted to rotate relative to said bearing according to the 'axis of the end of said tube and able to be made integral with the element driven in rotation.
  • the bearing member which encloses the end of the tube, will therefore be fixed by clipping onto it.
  • This member may have any shape allowing a free passage of the fluid in the tube, for example a stirrup shape, the ends of the branches of which will have a cylindrical profile allowing them to cover the end of the external surface of the tube and of which the part central uniting said branches will include an orifice or a recess for holding the pin.
  • the ends of the branches of the bearing enclosing the tube will be welded at a single point, so that the part of said bearing enclosing the end of the tube is fixed like a clip on this end.
  • a clamp will be provided, if necessary, to maintain in position on the end of the tube the part of said bearing enclosing this end.
  • This bearing can advantageously be obtained by cutting from a metal plate and stamping the cut shape to obtain the profile of said bearing.
  • the pin may include, in a simple manner, a rectilinear part, engaged in an orifice of the bearing member, one end of this part having a hook shape and cooperating with a ring-shaped end of the element driven in rotation, or vice-versa, while its other end will include a head now captive of said bearing.
  • This pin will advantageously be made in one piece.
  • the shapes of the hook of the journal and of the ring of the end of the element driven in rotation will be such that the point of contact between these two organs will be substantially located on the axis of the tube.
  • these will be made of materials capable of reducing their friction and, advantageously, an anti-wear washer will be interposed between these members.
  • said anti-wear washer has a sufficient thickness and that it is crimped into the bearing member.
  • Such a device is particularly well suited to maintaining in position the rotary members for preventing fouling and / or continuous cleaning of the tubes of the heat exchangers.
  • the tubes of the heat exchangers are generally engaged, at their two ends, in the orifices of a tube plate and they protrude slightly outside these tube plates, of a length of a few millimeters, which is sufficient. to make integral by clipping the bearing portion of the device according to the invention and the outside of the end of the projecting tube.
  • Another object of the invention is therefore constituted by the application of this device for holding in position in a tube, in particular a heat exchanger tube, of the end of a rotary member for preventing fouling and / or continuous cleaning of this tube.
  • This rotary member may have any shape known in the art, for example a helical shape, and be deformable or not. It may or may not be in contact with the internal wall of the tube.
  • the choice of the rotary member will depend, in practice, on the nature of the fluid borrowing the tube and, in particular, its viscosity, the dimensions of the tube and tolerable pressure losses in the installations of which they are part.
  • the device shown in FIGS. 1 and 2 comprises two essential parts, namely a member 1 forming a bearing for a journal 2.
  • These members will, for example, be made of stainless steel or mild steel.
  • the member 1 has a stirrup shape, of which only the parts 8a - 8b of the ends of the branches la and 1b, have the shape of a cylinder portion, allowing them to cover the outer surface of the end of a tube 3 which borrows a fluid (FIG. 2) and inside which is disposed a cleaning member 4, here of helical shape, driven in rotation by the fluid.
  • a fluid FOG. 2
  • a cleaning member 4 here of helical shape
  • the pin 2 comprises a straight part 2a engaged in an orifice 5 arranged in the center of the part 1c joining the branches 1a and 1b of the bearing 1.
  • One end 2b of the pin 2, disposed between the branches la and lb of the bearing 1 has a shape hook, while the opposite end 2c has a spherical or hemispherical head, preventing the pin 2 from being released from the bearing 1.
  • the tube 3 could be a duct of a heat exchanger, the end of which is engaged in a tubular plate 7 and protrudes by a few millimeters, for example three millimeters, outside this plate.
  • the protruding length of the tube 3 will be sufficient so that one can pinch its end using the ends 8a and 8b of the branches 1a and 1b. So that this pinching is sufficient to make the bearing 1 perfectly integral with the tube 3, the edges 9a and 9b or 10a and 10b of the ends 8a and 8b are welded to stiffen the opening of the bearing at these ends, said bearing being fixed like a clip on the end of the tube.
  • the rotary member 4 will have a ring-shaped end 4a, which will protrude outside the tube 3 and will be hooked to the end 2b of the pin 2.
  • the hook 2b of the journal 2 and the ring 4a of the rotary member 4 will have a shape such that the part of the ring housed in the hook is centered substantially on the axis X - X of the conduit 3, so that the pin 2 can itself be rotated about this axis, without a more complex movement being imparted to it by the member 4.
  • the ends 8a - 8b of the branches 1a and 1b of the bearing 1 have the shape of a ring part and they are enclosed externally, after positioning on the end of the tube to be fitted, by a split clamp 11.
  • the branches 1a and 1b of the bearing 1, in an exemplary embodiment of the device of Figure 4, have a total length of 39 mm, the width of the parts 8a and 8b is only 5 mm.
  • the internal diameter of the parts 8a and 8b is 25.4 mm and their external diameter of 27.4 mm.
  • the rectilinear part 2a of the pin 2 has a length of 10 mm and a diameter of two millimeters, while the head 2c is a sphere of 5 mm in diameter.
  • the collar 11 has an external diameter of 28 mm, an internal diameter of 27 mm and a width of 5 mm.
  • This embodiment of the device according to the invention serves to fix in position the end of a helical rotary member, whose turns have a diameter of 15 mm and a pitch of 22 mm, and whose total length is 6 m .
  • This rotary member consists of a metal wire of 1.2 mm in diameter and the turns are joined by a rod with a diameter of 1.2 mm.
  • the anti-wear washer 6 is crimped in the orifice 5 of the part 1c of the stirrup 1. This washer is of sufficient thickness to guide the pin which is introduced there.
  • the invention therefore provides a simple and easy to implement means for maintaining in position the end of a rotary member for preventing fouling and / or cleaning a tube, in particular a tube d 'heat exchanger.
