Definitions

  • the present invention relates to a splitter gate (hereinafter referred to as of the kind described) for dividing in an adjustable manner a stream of particulate or pulverulent material into at least three substreams, which gate comprises an inlet and at least three outlet ducts branching off from separate openings, where between the inlet and the outlet ducts is provided an intermediate section which comprises a chute forming an angle relative to the vertical so that the material stream is discharged from the lower edge of the bottom wall of the chute as a wide, flat, uniform stream, and which close to the lower edge of the chute comprises means for dividing the material stream into at least three outlet substreams.
  • a splitter gate hereinafter referred to as of the kind described
  • Our EP 0133762 discloses a splitter gate of the aforementioned kind.
  • This known splitter gate comprises a baffle plate which is rotatable about a vertical axis and constitutes the only adjustable component of the gate.
  • the material is divided by means of the stationary edges between the outlet openings into substreams of fixed mutual proportions being determined by the present position of the baffle plate in relation to the outlet openings.
  • a gate is utilized for dividing a material stream into e.g. three substreams, it will not be possible to vary freely the mutual proportions between the outlet material streams.
  • the dividing means may be formed in any suitable manner but it is preferred that they consist of plates which are fitted with their planes substantially at right angles to the bottom wall of the chute and extending in the direction of the material stream where the upper side edge of each plate is transversely displaceable relatively to the direction of the material stream.
  • each plate can be made displaceable in several ways.
  • each of the plates may be rotatably mounted at its lower edge so that the free end of each plate is pointing opposite to the flow direction and may be displaced in the transverse direction by angular displacement of the plate.
  • each of the plates may at its upper edge be rotatably mounted about a transversely displaceable axis, and hang down freely with its free end projecting into a respective one of the outlet ducts.
  • the splitter gate may advantageously comprise means for smoothing the material stream in the chute.
  • such smoothing means may consist of at least one flap which is rotatably suspended in the chute. To enhance the smoothing effect of the flap, it may biased towards the material in the chute by, e.g., a spring or a weight.
  • the bottom wall of the chute is planar.
  • the bottom wall In cases where the bottom wall is exposed excessively to the effect of heat, and consequently is subjected to a certain thermal expansion, the bottom wall will show a tendency to bend either upwards or downwards.
  • the bottom wall is designed with a concavely curved surface in the transverse direction. Hence, it is ensured that thermal expansion will always result in the bottom wall being bent further downwards.
  • the bottom wall of the chute may be designed so that its angle relative to vertical may be adjusted. However, during operation it is preferred that the bottom wall is stationary.

  • the splitter gate 1 shown in Figs, l and 2 comprises an inlet duct 2, an intermediate section 3 providing a chute, and three outlet ducts in the form of pipes 4, 5 and 6.
  • the bottom wall of the chute 7 constitutes a baffle plate which forms an angle relative to the axis of the inlet duct 2 so that it is struck by the material being fed which will thus be smoothed and discharged from the lower edge 7a of the bottom wall of the chute 7 as a wide, flat, uniform flow.
  • the splitter gate 1 comprises two plates 8 and 9 which are mounted in immediate continuation of the chute 7 at right angles in relation hereto and extending in the direction of the material stream indicated by the arrow 10.
  • the plates 8 and 9 are both rotatably mounted at their lower edges about a respective shaft 8a, 9a, and have their free ends 8b and 9b, respectively, pointing opposite to the direction of flow.
  • angular rotation of the plates 8 and 9 can be carried out manually by means of handles 11 fixed to the shafts 8a and 9a, but may also be carried out automatically using remote-controlled means, not shown.
  • the splitter gate 1 further comprises one or more flaps 12 which are each rotatably suspended in the chute 7.
  • the function of the flaps 12 is to ensure optimum smoothing of the material stream in the chute 7.
  • the latter may, as shown, be provided with a spring 13.
  • the two plates 8 and 9 of the splitter gate 1 could alternatively be fitted immediately above the bottom wall of the chute 7 at its lower end, being, in similar manner, rotatably mounted at its lower edge about a shaft which is at right angles to the bottom wall of the chute 7.
  • Fig. 3 is shown another embodiment of a splitter gate 31 according to the invention.
  • the difference between the splitter gate 31 shown in Fig. 3 and the splitter gate 1 shown in Figs. 1 and 2 relates primarily to the configuration of the means for dividing the material stream.

Abstract

L'invention concerne une grille (1, 31, 41) de séparation permettant de diviser d'une manière réglable un courant (10) de matière particulaire ou pulvérulente en au moins trois courants secondaires. La grille comporte une canalisation d'entrée (2) et au moins trois canalisations de sortie (4, 5, 6) se subdivisant à partir d'ouvertures séparées. Entre les canalisations d'entrée et de sortie se trouve un partie intermédiaire (3) comprenant un élément, tel qu'une chicane (7), formant un angle par rapport à l'axe vertical de manière que le courant de matière s'écoule sous le bord inférieur de la chicane sous forme de courant large, plat et uniforme. Au voisinage du bord inférieur de la chicane (7) se trouvent des éléments (8, 9; 38, 39; 48, 49) permettant de diviser le courant de matière en au moins trois courants secondaires de sortie. La grille est caractérisée en ce que les éléments diviseurs (8, 9; 38, 39; 48, 49) sont réglables de manière indépendante de façon que les proportions mutuelles entre les courants secondaires de sortie puissent être modifiées librement. Le courant de matière peut, en conséquence, être divisé en un nombre quelconque de courants secondaires de sortie selon les proportions mutuelles souhaitées.
