3 Claims. (01. 261-76) The present invention relates to a device for mixing a gas such as air with a liquid such as water, and, more particularly, relates to improvements in such a device for more intimately mixing a large volume of air with the liquid.
Accordingly, an object of the present invention is to provide 'a mixing device of the foregoing character wherein mechanical means effect mixing of the liquid and the air.
Another object is to provide such a device wherein a plurality of streams of liquid at a high Velocity are directed towards the mechanical means :to effect operation thereof.
Another object is to provide such a device wherein baffie means are provided at the downstream side of the mechanical means.
A further object is to provide such a device which is simple and economical in construction and reliable in operation.
Other and further objects will be obvious upon an understanding of the illustrative embodiment about to be described, or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
In accordance with the invention, the fore going objects are accomplished by providing a device comprising a chamber having an inlet adapted for connection to a source of liquid and having an outlet for discharging the jet, means such as an apertured disc for delivering a plurality of streams into the chamber at a high velocity, inlet ports in the chamber through which air is entrained by the streams of liquid, and mechanical means in the chamber, such as a rotatably mounted member having blades which means is operable by the streams of liquid for mixing the entrained air with the liquid.
In a preferred embodiment of the invention about to be described a baflie member is positioned at the down-stream side of the rotatable member and a second baflie member is positioned at the upstream side of the rotatable member having grooves for directing the streams of liquid against the blades, the baflle members and the rotatable member being supported by the disc at the downstream side thereof. The outlet end of the chamber has a converging wall which may be formed with stepped baiile faces and the baffle member at the downstream side may be stream-lined to cooperate with this wall.
A preferred embodiment of the invention has been chosen for purposes of illustration and description and is shown in the accompanying drawing, forming a part of the specification, where- 1n:
Fig. l is a longitudinal sectional view of a device in accordance with the present invention illustrating one embodiment thereof.
Fig. 2 is a sectional view taken along the line 2--2 on Fig. 1.
Fig. 3 is a sectional view taken along the line 3-3 on Fig. 1.
Fig. 4 is a longitudinal sectional view of a device in accordance with the invention illustrating another embodiment thereof.
Fig. 5 is a sectional view taken along the line 5-5 on Fig. 4.
Fig. 6 is a longitudinal sectional view of a device in accordance with the invention illustrating still another embodiment thereof.
Referring to the drawing in detail and more particularly to Figs. 1 to 3 thereof, there is shown an air and liquid mixing device which includes a body member ll] providing a chamber .having an upper inlet end I! adapted for connection to a water faucet l2 and having a lower converging outlet end 14 adapted for attaching a filter screen It thereto. The inlet end is formed with an annular shoulder I6 and the body member has air inlet ports in the form of circumferentially extending slits |l (Figs. 1 and 3), just below the shoulder [6.
A cup-shaped member I9 having a central disclike portion 20 formed with apertures 2| adapted to direct streams of water into the chamber (Fig. 3) is positioned in the chamber which is provided with an outwardly extending annular flange 22 at the upper end seated on the shoulder IE to support the member I9. A gasket or washer 24 is disposed between the flange 22 and the mouth of the faucet |2 to form a seal between. the body member and the faucet.
A baffle member 25 is positioned adjacent the outlet end which is in the form of a circular button supported on a rod-like section 26 secured to and suspended from the underside of the disc portion 20. Mechanical means for mixing the streams of water, such as an element 21 having blades 28, is rotatably mounted on the section 26 and is adapted to be rotated by the streams of water. A second bafiie member 30 in the form of a circular button is supported on the section 26 above the element 21 which has a plurality of peripheral recesses 3| disposed beneath alternate apertures 2| for directing streams of water against the blades 28 (Fig. 2).
In operation, when water is introduced into the chamber by way of the faucet |2, streams. of water are formed by the apertures 2| which are directed downwardly into the chamber to cause air to be entrained through the ports [1. Certain. of these streams strike the upper surface of the baffle 30 to deflect the same outwardly to produce turbulence and other streams strike the blades 28 to eifect rotation of the element 21 whereby the streams are given a swirling motion which cooperate with the deflected streams to thoroughly mix the water with the entrained air. The portion of the streams of water passing between the blades 28 strikes the upper surface of the bafile member 25 to further produce turbulence in the chamber which improves the mixing action. The baffle member 25 also serves to diverge the water passing through the chamber to impinge a portion thereof on the converging walls of the outlet end of the chamber which thereafter serve to direct the water through the outlet.
In Figs. 4 and 5, a modified device is shown which comprises a body member Ill providing a chamber having a converging wall at the downstream end formed with stepped baflle faces 35, an apertured disc 29a having a depending circular flange 35 adjacent the ports 11, and a bafile member 25a and a baille member 300, suspended from the disc a by a screw 31 on which an element 21 is rotatably mounted between the baffle members 2511 and 30a. The upper portion of the bafile member has circumferentially spaced peripheral recesses or grooves 38 for directing a portion of the stream downwardly while other portions of the stream are deflected outwardly. The lower portion of the bafile member 25a has a. section 39 of reduced diameter adjacent the outlet which is surrounded by the converging wall of the body member to streamline the flow of water as it is directed to the outlet.
In Fig. 6, another modified device is shown which is similar to the device shown in Figs. 4 and 5 except that the outlet has a flow directing nozzle 40 for applying the stream when used for washing dishes or shampooing hair and the like, and that a pear-shaped stream-lined baffie member 25b is provided.
From the ioregoing description, it will be seen that the present invention provides an improved device for producing a jet of liquid having air bubbles dispersed therein.
As various changes may be made in the form, construction, and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matters herein are to be interpreted as illustrative and not in any limiting sense.
What I claim is:
1. A device for producing a jet of liquid containing air bubbles comprising a chamber having an inlet adapted for connection to a source of liquid and having an outlet for discharging the jet, an apertured disc at the upstream end oi said chamber for delivering a plurality of streams of liquid into said chamber at a high velocity, said chamber having air inlet ports between said inlet and outlet through which air is entrained by the streams of liquid, and means supported on said disc at the downstream side thereof including a solid bailie member adjacent said outlet, a rotatably mounted member at the upstream side of said baffle member having a plurality of blades for mixing the entrained air with the liquid, and a solid baiile member at the upstream side of said rotatably mounted member having circumferentially spaced grooves for directing streams of liquid onto said blades to effect rotation of said rotatably mounted member.
2. A device according to claim 1, wherein said first mentioned baffle member has a plurality of circumferentially spaced grooves therein.
