  • the gear 84 and the flange 86 define through them arrangements of circumferentially spaced apertures 94 and 96, respectively. These arrangements are such that the angular position of the gear 84 relative to the flange 86, as determined by rotation effected by the stepper motor 88, determines the degree to which the respective apertures 94 and 96 are in register. With the respective apertures at least partially in register, they define inlets for the bypass air flow passage 78.
  • the motor 88, the reduction gearbox 90, the gear 92, the gear 84, and the flange 86 thus operatively serve as air flow control means for controlling air flow through the passage 78, as will be referred to again later herein.

  • the said first and second pipe sections thus form an arrangement of telescopically displaceable pipe sections that accommodate pivoting of the joint 24.
  • the said arrangement clearly defines an arc about the axis 102.
  • the boom pipe 42, the down pipe 20, and the pipe segment 104 define a suction pipe of the unloader unit 10.

  • Each line 108.2 is angularly spaced from the corresponding one of the lines 106.1 and 106.2 by an angle Y of approximately 135 ° corresponding to the pivot position of the joint 24 shown in Figure 7.
  • two limit swivel positions of the down pipe 20 are represented by broken lines 110.1 and 110.2, respectively, offset from vertical on opposite sides thereof by an angle ⁇ of approximately 20 ° .
  • Pendulum fashion displacement of the down pipe 20 between the two limit positions is provided for by the swivel joint 26 (see Figures 3 and 4).
  • the nozzle arrangement 74 can be maneuvered to reach substantially all positions in the hull of a ship required for unloading fluent material located therein.
  • a below-atmospheric pressure is thus created in the chamber 34 and, due to the pressure differential between the inlet 22 of the down pipe 20 and the chamber 34, air is displaced from the inlet 22, via the down pipe 20, via the pipe segment 104, via the boom pipe 42, and into the chamber 34. Fluent material at the inlet 22 defined by the nozzle arrangement 74 is displaced along with the air and collected in the vessel 32, from which it can be discharged through operation of the discharge arrangement 36. Insofar as the operation of unloader units of types similar to the unit 10 is known, it will not be elaborated herein in relation to the unit 10 specifically.
  • bypass air flow passage 78 provides for air to be displaced therethrough, then via the apertures 82, and then into the passage in the pipe segment 72.3 even when the bottom end of the nozzle arrangement 74 is submerged in bulk fluent material being unloaded by the unit 10 of Figure 1. Air flow into the passage in the pipe segment 72.3 may thus be maintained.
  • the velocity of such particles may be reduced to a level at which the degree of fragmentation of the particles upon impact with stationary material in the chamber 34 (see Figure 1) is limited to an acceptable level.
  • the perforated section 56 serves also as screening means for preventing particulate material from entering the bypass airflow passage 52.
  • Figure 10 shows a part of an unloader unit, in accordance with the invention, including an alternative arrangement of telescopic pipe sections to that shown in Figures 6 and 7.
  • Figure 10 shows many features that are similar to features shown in Figures 6 and 7. Such similar features are again designated by the same reference numerals as before and are not described again.
  • the arrangement of pipe sections comprises three rigid pipe sections 112.1 , 112.2, and
  • the section 112.1 forms a top end section of the down pipe of the unit whereas the section 112.3 forms an end section of the boom pipe 42, particularly of an end pipe segment 113 of the pipe 42.
  • the section 112.2 is an intermediate section intermediate the sections 112.1 and 112.3 and the joint 24 includes an arm 114 via which the section 112.2 is pivotally connected to the arms 98 and 100.
  • the sections 112.1 to 112.3 define an arrangement of pipe sections defining a constant radius arc around the axis 102 of the pivot joint 24. Through telescopic displacement of the pipe sections 112.1 to 112.3, pivot displacement of the joint 24 is accommodated.
  • FIG. 11 instead of the arrangement shown in Figure 2 for controlling air flow through a portion of the passage within the pipe 42 of the unit 10 of Figure 1 , another embodiment of a bulk materials handling unit, in accordance with the invention, includes an arrangement as shown in Figure 11.
  • the unit particularly is an unloader unit similar to the unit 10 of Figure 1 and includes a boom pipe 116 and a bypass pipe 118 running along side it and parallel to it.
  • the bypass pipe 118 defines therein a bypass air flow passage 120 which, at its downstream end, is in communication with the chamber defined in the pressure vessel of the unit and, at its upstream end, to the passage defined in the pipe 116 near its upstream end via an inlet 122.
  • the pipe 118 has air flow control means including a butterfly valve 124 for controlling airflow through the bypass air flow passage 120 - the equivalent of the control of air flow through the bypass air flow passage 52 (see Figure 2) via the sleeve 60. Again, by controlling the air flow through the bypass air flow passage 120, the velocity of the air flow in the pipe 116 is effectively controlled.

Abstract

L'invention concerne une unité de manipulation de matières pneumatiques, destinée, par exemple, au déchargement de matières fluides en vrac depuis des navires. L'unité comprend une structure de support, une flèche et un tuyau d'aspiration. Le tuyau d'aspiration comprend un tuyau de flèche qui fait partie intégrante de la flèche et un tuyau rigide orienté vers le bas qui définit une buse d'aspiration à son extrémité fonctionnelle inférieure. Il comprend aussi une articulation qui sert à relier le tuyau de flèche et le tuyau orienté vers le bas de manière pivotante; l'articulation comprend un système d'au moins deux parties du tuyau pouvant se déplacer de façon télescopique qui relient le tuyau de flèche et le tuyau orienté vers le bas. Ce système définit un arc dans le tuyau d'aspiration autour de l'axe de l'articulation et permet de le pivotement fonctionnel de l'articulation par le déplacement télescopique de ses parties du tuyau. L'unité permet la manipulation efficace de la buse d'aspiration dans des espaces restreints dans lesquels se trouvent les matières qu'elle doit décharger.
