  • ABSTRACT A device for introducing a gas into a liquid, as for depollution of a stream or pond.
  • a rotatable shaft, jour nalled in floating or fixed bearings, has radial extensions formed both by propelling plates and brush parts.
  • the propelling plates and brushes may be secured to a hollow core, which is fastened to the shaft, and the weight of the whole device may be lower than the lifting power of the liquid on the device.
  • the propelling plates may be helically arranged around the shaft, so that a continuous rotation of the shaft is obtained by the stream of the liquid, and the propelling plates may be prolonged in tangential direction to increase the propelling force thereof.
  • the brushes may rotate relatively to the shaft.
  • a guiding gutter may be provided at the area of the propelling plates, water being pushed through the gutter for causing the shaft to rotate, and the gutter may have a venturi-like section.

AT TORNEYS APPARATUS FOR SUPPLYING A GAS, ESPECIALLY AN OXYGEN INTO A LIQUID This is a continuation of application Ser. No. 93,240, filed Nov. 27, 1970, now abandoned.
  • This invention relates to a device for introducing a gas into a liquid, and it relates, more particularly to such a device including a rotatable shaft provided with extensions and journalled in floating or fixed bearings. It has important applications in anti-pollution devices, such as, for example, de-pollution of rivers and streams.
  • the devices hitherto known have the disadvantage thet they have all had to be driven by electric motors or by combustion engines or the like.
  • the present invention attempts to obviate this disadvantage.
  • the device for introducing a gas into a liquid includes a shaft with extensions and is characterized by the extensions being formed by propelling plates and brush parts.
  • the propelling plates which may be venturi-shaped, are preferably arranged helically around the shaft, so that a continuous rotation of the shaft is obtained by the stream of the liquid in which the device is partially immersed.
  • the rotation of the shaft may be improved by providing guide gutters such that the liquid stream is increased at the area of the rotatable shaft. If the device of the invention is to be used in stagnant water, water movement may be produced with the aid ofa rotatable screw, in front of or behind the rotatable shaft, having propelling plates and brush parts. Such movement of water is preferred, for example, to driving the shaft, because the introduction of the gas into the liquid is thus improved.
  • FIG. 1 shows schematically in side elevation a rotatable shaft provided with propelling blades and brush parts
  • FIG. 2 is a sectional view taken along the line II--II of FIG. 1;
  • FIG. 3 shows schematically in perspective a rotatable shaft having helical propelling blades
  • FIG. 4 is a sectional view of a rotatable shaft having brushes adapted to rotate relatively to the shaft and to a guide gutter;
  • FIG. 5 is a plan view which shows a further embodiment of a rotatable shaft having propelling blades and brush parts also with a guide gutter.
  • a rotatable shaft 1 is provided with a core 2 having propelling blades 3 and brush parts 4.
  • the core 2 may be made of polyvinylchloride or socalled hard foam or of polyester with glass fibre reinforcement, and it is preferably hollow so that the assembly can float.
  • the propelling blades 3 are preferably secured on the core 2 in staggered positions.
  • the arrangement may be such that, for example, the propelling blades 3 can be exchanged.
  • On the core 2 are also fastened, if desired in an exchangeable manner, the brush groups 4.
  • the lengths of the brushes 4 are such that a large quantity of air is enclosed during that part of the period of revolution in which the shaft 1 and the brushes 4 are located above the liquid level 5, the air being given off in the water during the part of a revolution in which the brushes are located in the liquid.
  • the rotatable shaft 1 may be journalled in floating or fixed journals in accordance with the necessary requirements and conditions.
  • FIG. 3 shows an embodiment in which the propelling blades 3a are arranged helically, which may result in a uniform rotation of the shaft 1.
  • the propelling blades 3b are also provided with projecting parts 6 which may be perpendicular to the radial blades 3b, i.e., may be prolonged in the tangential direction.
  • the blades 3b may be made of a flexible material and may be interconnected by wires 7.
  • Such an embodiment is preferably used in stagnant water, in which case a gutter-shaped guide plate 8 is preferably arranged in the area of the propelling blades, through which gutter 8 the liquid 5 is pushed by means of the driven helices, a pump and the like.
  • liquid 5 may be preferably to cause the liquid 5 to move instead of driving the shaft 1 along with the core 2.
  • a flow is thus produced in the liquid 5, for example, in a pond, so that the whole quantity of liquid in the pond from time to time comes into contact with the brush parts of the shaft, so that the whole of the liquid is purified.
  • the brush parts 4 may be adapted to rotate relatively to the shaft 1, for example, by fastening separate shafts 9 to the shaft 1 so that the shafts 9 can rotate relatively to the shaft 1. This may be achieved by means of suitable gear wheels, and
  • FIG. 5 shows a further embodiment in which the shaft 1 is journalled in bearings 10, which may be fastened to floats, whilst the propelling blades 3, which may have a helical shape or a shape as shown in FIG. 4, cause the shaft 1 to rotate.
  • a gutter 8 is again provided.
  • the shaft 1 is provided with geared wheels 11, which mesh with the geared wheels 12 of a shaft 13, to which the brush parts 4 are secured.
  • the shaft 13 is journalled in bearings 14 and 15 which are fastened to the bearing part 10.
  • the whole structure may be caused to float on this hollow core so that the shaft 1 need only be anchored with the aid of anchors, lines and the like.
  • the gutters 8, when employed, may have a shape such that the speed at the area of the propelling blades gives rise to a higher speed of the stream so that a high propelling pressure is produced. This may advantageously be used in flowing liquids, but also in liquids being caused to flow. This may be achieved by a venturi-shaped structure or section of the gutter 8.
  • the shafts with the extensions for introducing the air into the liquid may rotate in the same senses or in opposite senses, depending on the arrangement of the intermediate gear wheels.
  • a device for introducing a gas into a liquid comprising a freely rotatable shaft having associated therewith radial extensions formed by alternate propelling plates and brushes, each of said brushes, in use, enclosing therein a large quantity of air during the period of the revolution cycle when the brushes are positioned above the level of said liquid, said plates being adapted to cause rotation of said shaft and brushes by contact with a stream of liquid when partially immersed therein, said propelling plates being helically shaped and helically arranged around the shaft alternatively with said brushes so that a continuous rotation of the shaft is obtained by the stream of liquid.
  • a device for introducing a gas into a liquid comprising a freely rotatable shaft having associated therewith radial extensions formed by alternate propelling plates and brushes, each of said brushes, in use, enclosing therein a large quantity of air during the period of the revolution cycle when the brushes are positioned above the level of said liquid, said plates being adapted to cause rotation of said shaft and brushes by contact with a stream of liquid when partially immersed therein, said propelling plates and brushes being secured to a floatable hollow core, which is fastened to the shaft, said core being formed of polyvinyl chloride or polyester reinforced with fibre glass or hard foam.
