Definitions

  • the invention relates to a device provided with a reservoir for receiving a liquid and a rotor arranged in said reservoir, said rotor being rotatable about its central longitudinal axis and having blades distributed over its circumference, said blades being shaped such that when the rotor is rotated a liquid is sucked in towards said blades in a direction extending transversely to the axis of rotation of the rotor, whilst near the rotor there is arranged a first end of a pipe having an other end in flow communication with a further reservoir.
  • Such a device is known from FR-A-2,241,704 (& NL-A-7 311 537).
  • the first end of the pipe is situated at some distance from the rotor when seen in the direction of the central longitudinal axis of the rotor.
  • the purpose of the invention is to obtain a device of the above kind whereby it is possible that the liquid present in the reservoir, at the same time as it is being agitated by means of the rotating rotor, can be mixed in an effective manner with a material to be drawn from one or more other reservoirs, such as liquid or gaseous substances, which may also contain solid substances.
  • US-A-3,773,302 discloses a device having a disc shaped impeller arranged in a reservoir and displacing liquid in an outward direction during operation. In line with the axis of rotation of said impeller there has been arranged the end of a pipe which is in communication with a further reservoir.
  • Fig 1 is a diagrammatic side view of a device according to the invention.
  • Fig 2 is a top view of the device illustrated in fig 2, whereby the rotor has been left out.
  • Fig 3 shows on a larger scale a part of the device illustrated in fig. 1.
  • the device illustrated in fig 1 comprises a first reservoir 1 and a reservoir 2 arranged therebeside.
  • the reservoir 1 is intended for being used as an aerating basin of a water purification device, whilst the reservoir 2 is intended to act as a settling basin.
  • a rotor 3 e.g. of the type described in the Dutch patent application 73111537 or 7807073, for agitating the liquid present in the reservoir 1.
  • the rotor 3 is fixed to a hollow shaft 4, which is mounted on a motor 5, by means of which the shaft 4 with the rotor 3 can be rotated.
  • the motor 5 is adjustably supported by a frame part 6 having a fixed connection to the reservoir 1.
  • the liquid to be purified can be supplied to the reservoir 1 via a supply pipe 7.
  • a gutter 8 extending along one side of said reservoir and parallel to the longitudinal direction of the reservoir 1, said gutter being in communication with the reservoir 1 at one end, at a point located under the liquid level of the reservoir 1.
  • Liquid can thus flow from the basin 1 into the gutter 8.
  • the bottom of the gutter 8 there are provided a number of regularly spaced holes 8′, so that the liquid, with the silt present therein, can flow into the reservoir 2, whereby the silt will settle in said reservoir.
  • Purified water can be discharged from the reservoir 2 through a discharge pipe 9 arranged in the reservoir 2.
  • a pipe 10 extends along part of its length into the reservoir 2, whereby the open lower end of said pipe is located at some distance from the bottom of the reservoir 2. From said lower end the pipe is led upwards and with one bent end through or over the partition wall 11 separating the two reservoirs 1 and 2. The arrangement is thereby such that the open end of the part of the pipe 10 passed through the wall is located near the side of the rotor.
  • an extension piece 13 may be movably provided on the end of the pipe 10 located near the rotor 3, which extension piece can be fixed to the pipe 10 in any position desired by means of clamping means 14.
  • clamping means 14 the distance between the outer circumference of the rotor and the mouth of the pipe 10 can be adjusted in order to be able to regulate the degree of suction of silt from the settling reservoir 2 therewith.
  • shut-off valve may be mounted in the pipe 10, for interrupting the passage of material through the pipe 10.
  • the pipe 10 may be constructed with a bend above the liquid level in the reservoir 2, whereby the relevant shut-off valve or the like can be incorporated, easily operable, in the part of the pipe 10 located above the liquid level.
  • the end of the pipe fitted with a flexible part in that case, may have a fixed connection to the motor, so that when the motor with the shaft and the rotor are pivoted the distance between the end of the pipe 10 and the rotor 3 remains unchanged.
  • the shaft 4 may be solid in that case.
