Definitions

  • the present invention finds more particularly its application in mechanical smoke extractors for chimneys, but it could also be adapted to all types of ducts requiring air extraction from an industrial or domestic premises, and likely to require cleaning or maintenance.
  • Known vacuum cleaners of this type are formed in a known manner by a rotary turbine, integral with a free part of a vertical axis, rotated under the action of an actuating force, and one of which lower end zone is journalled in a bearing by through at least one element such as bearing or ball bearing, immersed in a bath of lubricating oil and placed in the center of a adapter flange fixed to the chimney flue by connecting arms radial.
  • the actuating force of the rotary turbine is in some cases formed by the wind acting on the blades of the turbine. In other case, this actuating force is constituted by an electric motor rotating the blades of a turbine controlled by the engine.
  • the object of the present invention is to remedy these various disadvantages related to the tightness of the device, while allowing access completely free from the duct during maintenance or repair.
  • the invention relates to a mechanical smoke extractor for chimney flue of the type constituted by a rotary turbine, integral a free part of a vertical axis, rotated under the action of a driving force and having a lower end region mounted swiveling in a support bearing by means of at least one element such as bearing or ball bearing, immersed in an oil bath lubrication and placed in the center of a flange for adaptation to the duct by radial link arms arranged between the latter and said bearing support, characterized in that all of its constituent elements, except for the adaptation collar, form a retractable mobile assembly, by lateral release, thanks to removable fixing means of the arms radial connection on said flange, one of these fixing means being consisting of a hinge pin arranged vertically in an area fixed device of the flange and cooperating with a bore made at the free end of one of the radial link arms, so as to make said free movement in a horizontal plane by rotation around the fixed vertical axis, in one direction or the other, to
  • the present invention also relates to the features which will emerge during the description which follows.
  • the mechanical smoke extractor 1, shown in FIG. 1, is intended for a chimney flue 2 and it is constituted, for example, by a rotary turbine 3 comprising, in a manner known per se, fins 3a and made integral with a free part 4a of a vertical axis 4, driven under the action of an actuating force, in this case the wind, and of which an area lower end 4b is pivotally mounted in a support bearing 5.
  • a rotary turbine 3 comprising, in a manner known per se, fins 3a and made integral with a free part 4a of a vertical axis 4, driven under the action of an actuating force, in this case the wind, and of which an area lower end 4b is pivotally mounted in a support bearing 5.
  • the bearing support 5 consists of two upper ball bearings 7a and lower 7b immersed in a lubricating oil bath 6, said support bearing being closed at its upper part by a plug-forming element 8.
  • the support bearing 5 is arranged in the center of an adapter collar 9, designated in its assembly, which is intended to be fixed to the duct 2 by link arms radials 10 derived from and obtained from material during the same operation of molding with bearing 5.
  • all the constituent elements of the vacuum cleaner smoke mechanics 1, namely: the rotary turbine 3, the axis 4, the bearing 5, the oil 6, the support bearing 7, the closing element 8 of the bearing 7, the arms of radial link 10, form a movable assembly 11 fully retractable by lateral clearance with respect to the adaptation collar 9 which is itself of course fixed relative to conduit 2.
  • the lateral clearance of the mobile assembly 11 is obtained by means of removable fixing means for all of the radial link arms 10 on said fixed collar 9.
  • One of these fixing means is constituted by a hinge pin 12 arranged vertically in a fixed peripheral zone 13 of the flange 9 and cooperates with a bore 14 made at the free end of one of the arms connecting radials 10A.
  • the mobile assembly 11 is made free of travel in a horizontal plane by rotation around said fixed vertical axis 12, in a one way or the other, to allow either free access to conduit 2 within sight of its maintenance, ie its recovery in operation.
  • the axis articulation 12 is constituted by a screw capable of passing through a hole 14 in the arm radial 10A to be screwed into a threaded hole 15 made in a appendix 16 constituting the peripheral zone 13 of the collar 9.
  • a sleeve 17 is introduced into the hole 14 of the radial arm 10A, of a height slightly greater than the height of this hole, so that the screw 12 is blocked on said sleeve 17, which prevents the blocking in rotation of the radial arm 10A.
  • the retractable assembly 11 rotatably mounted about the vertical axis articulation 12, via one of these radial link arms 10A, comprises a second radial link arm 10B whose free end is extended by a locking means 18 intended to cooperate with a complementary means 19 disposed at the outer periphery of the fixed flange adaptation 9.
  • the locking means 18 produced on the second radial link arm 10B is constituted by a light produced on an extension 20 of the end of said arm 10B folded vertically, to form a tab able to cooperate with the body of a screw constituting the complementary means lock 19 which is engaged radially in a threaded hole 21 of the side wall 9A of the flange 9, and coming to clamp against the tab 20 the contacting of which with said fixed flange 9 corresponds to centering of the movable assembly 11 relative thereto.
  • the lumen 18 of the locking tab 20 is oblong shape, open at one end directed towards the screw 19 to define a U whose branches 18a, 18b extend horizontally on either side of the longitudinal axis of the light 18 which they delimit, the center O of the background rounded 18c thereof corresponds to the axis xx 'of the locking screw 19.
  • the locking tab 20 comprises, in an area lateral opposite the open end of its lumen 18, an extension 22 extending substantially radially outward and forming a grip manual maneuver in rotation of the movable assembly 11 in one direction or in the other.
  • the mobile assembly 11 comprises a third link arm 10C with the fixed collar 9, of which the free end forms a tab 23 produced in a horizontal plane, and on the outer periphery of which is formed a groove 24, also carried out according to a horizontal plane, which is capable of cooperating in closure with a corresponding tooth 25 projecting from the inner wall device 9B of the flange 9, so as to obtain a fixing in three points of the mobile assembly 11.
  • the peripheral side wall 9A of the adapter flange 9 comprises, to the right of the clamping screw 19, a notch 26 of relative height h1 capable of allowing the passage of the lug 23 of the radial link arm 10B, during the rotation of the assembly around of the vertical hinge axis 12.
  • a second notch 27 In the peripheral extension of the notch 26, is made a second notch 27 whose relative height h2 is able to allow the passage of the bottom 5a of the support bearing 5, during the same rotation for perform the lateral release of the mobile assembly 11.
  • adaptation collar 9 is secured to conduit 2 by means of four fixing hooks 28 driven in tightening against the internal wall of the duct 2 by nuts with fins 29.
