Definitions

  • This invention concerns a unit for the cleaning of shafts or pipes and consits of a brush rotating around an axis; this brush is designed mainly for filling in the shaft or pipe section, and the brush is designed to rotate by means of the fluid pressure.
  • this brush is designed mainly for filling in the shaft or pipe section, and the brush is designed to rotate by means of the fluid pressure.
  • the purpose of the present invention is that of pointing to a unit which is particularly suitable for cleaning vertical shafts, preferably waste chutes.
  • the unit to the invention is characteristic in that the unit has been suspended in a bearing, in that there are means of hoisting the unit up and down, in that between the bearing and the brush liquid nozzles with directions have been mounted, the latter providing a reaction torque when the liquid is sprayed out, and in that the unit is connected at the underside with fluid pressure hose over a rotating coupling so that the unit may rotate without the hose rotating, too.
  • One mode of design of the unit is characteristic in that in front of each nozzle viewed in the rotation direction clamps or plates have been mounted inside the circle surface described by the nozzles, stretching mainly tangentially forward from each nozzle.
  • This design is particularly suitable for waste chutes having insertion openings at the sides, these being most generally used.
  • the chute will not have a cylindrical shape inside but a somewhat larger section which will deviate from that of a cylindrical shape. The clamps will thus prevent the unit from getting stuck. or being braked in its rotation by the passage of any such extended sections.
  • Fig. 1 shows in part a vertical section in a waste chute in a house in which a unit to the invention has been placed
  • Fig. 2 the unit to a particularly suitable mode of design on a larger scale, partly in section and without means of hoisting & liquid supply, and Fig. 3 this unit viewed from above.
  • Fig. 1 shows a residential house 1, equipped with a waste chute 2. At the individual floors, there are insertion gates 3, 4, 5, and 6, and at the bottom an exhaust outlet 7. The actual unit 8, shown in Figs. 2 and 3, have been suspended in actually known hoisting means 9. Obviously, mechanical hoisting means may be connected at the top. Below, the unit has been connected to liquid supply means through a hose 10.
  • the unit to Figs. 2 and 3 has been equipped above with a suspension ring 11, mounted in a bearing 12, so that the ring 11 may rotate freely around a vertical axis in relation to the other part of the unit.
  • the unit is equipped with two nozzle arms 13 and 14 at the outer ends of which high pressure nozzles 15 and 16 have been mounted, directed partly radially and partly tangentially outwards.
  • Nozzles 15 and 16 are supplied with cleaning liquid through arms 13 and 14 which are hollow, and connected with a central supply canal 17, below connected with a quick-coupling unit 18 which over a svivel coupling 19 has been designed to rotate freely in relation to the other part of the unit in the same manner as that of the ring 11.
  • a circular brush 20 has been mounted; it has a diameter a little larger than the diameter on which nozzles 15 and 16 have been placed.
  • clamps 21 and 22 have been mounted, running at the horizontal level, at which nozzles 15 and 16 have been designed to rotate.
  • the part carrying nozsles and brush When the unit has been suspended in a vertical shaft as shown in Fig. 1, the part carrying nozsles and brush will be able to rotate freely in the chute in relation to the other parts, and the vertical orientation of the unit axis will be quite stable because there is a central tension in the unit from both sides.
  • the unit may, when rotating and colliding with a point or a minor stretch at the chute wall, very easily perform oscillations in the form of precession-like movements at the horizontal level. Thus, a considerable amount of certainty is provided with respect to the cleaning of all the areas of the chute wall which will in a given position be radially outside the brush. If the section of the chute is not altogether circular, such as is the case of insertion openings, clamps 21 and 22 will prevent nozzles 15 and 16 and nozzle arms 13 and 14 from getting damaged and the rotation from being braked.
  • This invention is not limited to the use of the unit with two nozzles and one brush, and clamps 21 and 22 may just as well be replaced by plates.
  • clamps 21 and 22 may just as well be replaced by plates.
