A perspective view and a partially cutaway perspective view of the discharge portion, and Figure 11 is a schematic illustration of a state in which the aeration stirrer according to the present invention is installed in the aeration tank, respectively.

That is, the multi-aeration stirrer A according to the present invention is provided with a central chamber 10 in which the liquid 3 is located, as shown in FIGS. 1 to 11, and the liquid is disposed at one side of the central chamber 10. The inlet part 21 is provided, and the functional connection part 41 is provided on the other side, and the liquid discharge part 31 is provided on the outer side of the central chamber 10.

Therefore, the liquid 3 in the aeration tank 2 is introduced into the central chamber 10 and then discharged to the liquid discharge part 31 again, so that the liquid 3 is mixed evenly in the aeration tank 2. .

In particular, the multi-aeration stirrer (A) according to the present invention includes a functional connection portion 41 is connected to one side of the liquid discharge portion 31 so that any one or more substances of liquid, aeration air, and aeration agent are supplied. It is characterized by being provided.

In particular, since the overall shape of the liquid discharge portion 31 of the multi-aeration stirrer A according to the present invention has a narrow tube shape that becomes narrower gradually toward the outward direction, the liquid discharged from the liquid discharge portion 31 is separated. (3) is discharged by a strong pressure. The liquid 3 inside the aeration tank 2 is agitated by the force of the strong wave by the liquid 3 discharged at such a high pressure.

In addition, when air or aeration agent is supplied to the functional connection portion 41, the liquid 3 discharged from the multi-aeration stirrer (A) is to perform aeration afterwards, so the multi-aeration stirrer according to the present invention By (A) there is an advantage that the aeration and agitation can work together.

Looking at the detailed configuration of the multi-aeration stirrer (A) according to the present invention provided as follows.

The central chamber 10 is provided on the central side of the multi-aeration stirrer A, and one or more liquid discharge parts 31 are provided on the outside of the central chamber 10.

The central chamber 10 may be formed in various forms such as a horizontal cross-sectional shape of a polygonal, circular enclosure or pipe.

In particular, as shown in Figs. 1 to 4 may be provided in a cylindrical shape, an elliptical cylinder shape, a polygonal cylinder shape and the like to have a central axis in the transverse direction of the drawing. In addition, as shown in FIGS. 5 to 11 may be provided in a cylindrical shape, an elliptical cylinder shape, a polygonal cylinder shape, etc. to have a central axis in the vertical direction of the drawing. Alternatively, the central chamber may be formed in a pipe shape and installed in various directions such as a transverse direction, a longitudinal direction, or an oblique direction in the aeration tank, and may be provided so that the discharge part may be formed in a plurality of pipe-shaped central chambers. Therefore, it is provided in a tubular shape in various forms, it may be provided so that the liquid 3 supplied from the aeration tank 2 therein temporarily.

And the side of the central chamber 10 is provided with a plurality of liquid discharge portion 31 is connected.

Of course, the liquid discharge portion 31 may be formed to extend outward with respect to the horizontal side of the central chamber 10 as in the examples of the accompanying drawings. In addition, as shown in FIG. 7, the liquid discharge part 31 may be provided in such a manner that the liquid is discharged in an acute angle (a) direction with respect to a normal direction with respect to the side surface of the central chamber 10.

In addition to the other horizontal direction, the liquid discharge portion 31 may be provided on the outer surface of the central chamber 10 so as to be directed upward or downward, or horizontal, upward, downward, etc. are combined with each other.

Thus, according to various external conditions such as the conditions, size, structure for supplying liquid to the aeration tank 2, and the structure for discharging the aerated liquid from the aeration tank 2, In addition, the shape of the central chamber 10 may be determined, or the number and position of the liquid discharge part 31 and the discharge direction may be appropriately set.

The multi-aeration stirrer (A) according to the present invention provided as described above is a process of mixing with the air, liquid, or aeration agent of the functional connection portion 41 is discharged while the liquid 3 contained in the central chamber 10 is discharged will be.

Looking at the detailed configuration of the liquid discharge portion 31, the internal nozzle 32 to discharge the liquid in the central chamber 10; An outer nozzle 33 surrounding the inner nozzle 32 to discharge the liquid mixed with at least one of liquid, air, and aeration agent supplied from the functional connection part 41 to the outside; Mixing is formed in the central portion of the outer nozzle 33 in order to mix at least one of the liquid supplied from the inner nozzle 32 and the liquid, air, aeration agent supplied from the functional connecting portion 41 with each other The chamber 34 is provided to be included.

That is, the inner nozzle 32 in which the liquid in the central chamber 10 is discharged is connected to the inner center of the liquid discharge part 31 in a relatively small size. And the outer nozzle 33 is provided in such a way that gradually narrowing while wrapping the inner nozzle (32). Of course, the inner nozzle 32 or the outer nozzle 33 may be formed such that the discharge end is narrower to the end than the inlet side, as in the example of the accompanying drawings, depending on the conditions such as function or aeration tank It may be formed in a variety of forms, such as a form to be expanded to the outside or to have the same diameter.

However, in the case of being formed in the narrow tube shape to narrow gradually toward the outward direction, the liquid 3 introduced into the inner nozzle 32 or the outer nozzle 33 at the same flow rate flows more rapidly at the relatively narrow end portion, and eventually the inner nozzle. The liquid after being discharged from the 32 or the external nozzle 33 is faster than the first flowing time and has a strong pressure.

Thus, the liquid discharged from the internal nozzle 32 and introduced into the mixing chamber 34 is stirred well with the material supplied from the functional connection part 41, and the liquid discharged from the external nozzle 33 and discharged to the outside (3). ) Has a strong pressure to act to force the other liquid in the aeration tank (2). Therefore, the liquid flowing at a high pressure from the aeration tank (2) has the advantage that the agitating action naturally in the aeration tank (2) without a separate stirring member.

The mixing chamber 34 is formed in the center of the outer nozzle 33 to form a mixing space which is a space in which the liquid 3 of the inner nozzle 32 and the material of the functional connection part 41 are mixed. Therefore, when aeration air or aeration agent is supplied from the functional connection part 41 side, the liquid 3 and air or aeration agent are evenly mixed with each other in the mixing space formed by the mixing chamber 34. That is, as shown in FIG. 2, the liquid discharged from the internal nozzle 32 with a high pressure is small in the process of mixing by a material such as air or aeration agent from the functional connection part 41, so that a large number of small vortices are formed. Will be more evenly mixed. Particularly, when air and liquid are mixed to form microbubbles of droplets, the mixture is better mixed with the liquid, so that the dissolved oxygen becomes liquid and the aerobic action is more actively performed.

These forms may be provided in various ways by factors such as what is the aeration tank and the corresponding liquid or what the processing capacity, the material supplied from the functional connection 41.

In particular, as shown in FIGS. 1 and 2, a mixing chamber 34 is formed at the middle of the outer nozzle 33 of the conical barrel to protrude outward in a streamlined or polygonal shape (not shown) to form a mixing space. Can be done. In this case, since a large number of small vortices are formed in a large space in which the liquid discharged from the internal nozzle 32 and drawn into the mixing chamber 34, which is a mixing space, is formed, the air supplied from the functional connection part 41 is further increased. It has the advantage of being well stirred. Therefore, the configuration in which the mixing chamber 34 is formed on the outer nozzle 33 will be referred to as one of the main features of the present invention.

As shown in FIG. 8, one or a plurality of bubble expanding wings 341 are attached to the inner nozzle 32 in an oblique helical direction with respect to a wall surface of the inner nozzle 32 and are formed in a semicircular shape or a half moon shape. It is provided. Thus, the liquid 3 discharged through the inner nozzle 32 is rotated to cause a vortex, thereby causing a whirlwind of the vortex in the mixing chamber 34 of the outer nozzle 33. Thus, since the liquid is easily mixed by the vortex of the air and the vortex which flows in through the functional connection portion 41 connected to the outer nozzle 33, the air is made into microbubbles of small bubbles, and thus more and more in the liquid. Oxygen is mixed. Therefore, aerobic reactions are more likely to occur in liquids having smaller bubbles, smaller bubbles, and more dissolved oxygen.

In addition, the shape of the functional connection portion 41 for introducing the material into the mixing chamber 34 may be variously formed. That is, as shown in FIGS. 3 and 4, the functional connection part 41 may be provided using only the supply connection part 43 connected to the outer surface of the external nozzle 33 of the liquid discharge part 31.

In addition, as shown in FIGS. 1 and 2, and 5 and 11, a concentrator 42 connecting the plurality of supply connections 43 may be formed. The concentrator 42 is formed in the shape of “ㅗ” as shown in FIGS. 1 and 2, and is coupled to both ends of the supply connection part 43 at both ends of the lower side, and an air supply is provided at an upwardly extending portion. Pipes (or hoses) may be connected.

1 and 2, the liquid supply pump 4 (or supply pipe, hose, etc.) for pumping the liquid 3 in the aeration tank 2 to the liquid inlet 21 at the lower side is connected. In this case, the liquid 3 is filled in the central chamber 31 by the operation of the liquid supply pump 4, and the liquid 3 compressed in the central chamber 31 is the internal nozzle of the liquid discharge part 31. 32). Subsequently, the liquid 3 passes through the mixing chamber 34 of the external nozzle 33 and is connected to the supply connection 43 of the functional connection 41 to be mixed with air or liquid.

When the liquid is contained in the central chamber 31 by the liquid supply pump 4 for the liquid 3 inflow, while the air is supplied to the central portion 42 of the functional connection portion 41, the mixing chamber 34 Air and liquid are mixed in the aerobic and stirring process.

In addition, when the liquid in the aeration tank is also supplied to the concentration portion 42 side of the functional connection portion 41, since only liquid is supplied into the mixing chamber 34 and no air is supplied, the aerobic action is performed without oxygen supply. Will be done.

Furthermore, when the liquid is supplied to the central chamber 31 and the medicine such as an aeration agent is supplied to the concentrated portion 42 of the functional connection portion 41, the medicine and the liquid are evenly mixed.

In particular, the aerobic action, anaerobic action and the action of mixing the drug can be applied not only from the upper side of the aeration tank 2, but also deep inside the large aeration tank 2, so that the aerobic action as a whole, aerobic action, anaerobic action, drugs There is an advantage that the mixing process and the stirring action is made well.

Therefore, in the case of a large aeration tank as shown in Figure 11, there may be provided a separate liquid supply pump (4) and air pump (5) and a chemical tank (not shown) for the drug supply.

That is, a liquid supply pump 4 connected to the liquid inlet 21 and supplying the liquid contained in the aeration tank 2 to the central chamber 10 side may be provided, and is connected to the functional connection part 41. An air pump 5 for supplying air to the mixing chamber 34 may be provided.

In addition, when the horizontal cross-sectional shape of the central chamber 10 is formed in a hexagon as shown in Figure 5 to 11, etc., the liquid discharge portion 31 may be provided on each outer surface, such liquid discharge portion 31 and The functional connection portion 41 to be connected may be provided so that the central portion 10 is provided with a concentrating portion 42 in a large tubular shape. The concentrator 42 is fixed by the connection column 44 fixed to the central chamber 10, and the concentrator 42 and the supply connection unit 43 are connected by the connection hose 45 to supply air. It may be provided to be.

And, as shown in Figure 7, the liquid discharge portion 31 may be provided so as to form an acute angle (a) rather than parallel to the normal of the outer surface of the central chamber (10).

Thus, since the flow direction of the liquid 3 to be discharged is inclined to the side and discharged, it may be provided so that the stirring effect is better.

Therefore, when a plurality of liquid discharge portion 31 is formed in the multi-aeration stirrer (A) according to the present invention, the multi-type aeration having a multifunction by the air pump 5, the liquid supply pump (4) and the like for aeration blower and In the multi-aeration stirrer (A), the microbubble and the liquid are mixed first and then sprayed in the mixed state to increase the contact efficiency between the liquid and the gas. Aeration efficiency is provided to be superior.

Thus, the supplied air and the discharged liquid are more evenly vortexed by the formation of more vortices in the mixing space, which is a larger space. Therefore, the residence time of the liquid in the mixing space where the micro-bubble air and the liquid is mixed, so that the amount of dissolved oxygen in the liquid is increased, the aeration can proceed more actively.

In addition, in the multi-aeration stirrer (A) according to the present invention, as shown in Figs. 9 and 10, the liquid discharge portion 31 is an active appearance 35 so that the end of the outer nozzle 33 is wrapped ) Is provided. In addition, the external appearance part 351 is provided such that the active exterior part 35 is fixed to the external nozzle 33.

According to the active appearance part 35 provided in this way, liquid and air are mixed and discharged to the discharge part of the end part of the outer nozzle 33 of the liquid discharge part 31, and this liquid discharge part 31 is carried out to a liquid. In the immersed state, the liquid in the vicinity of the liquid discharge portion 31 is sucked into the inner end of the active appearance portion 35 by the flow pressure of the discharged liquid.

In more detail, when the liquid is discharged to the end of the outer nozzle 33 of the liquid discharge portion 31, a relatively low pressure is formed around the vicinity of the liquid discharge portion 31 by the discharge pressure of the liquid. When the relative low pressure is formed in this way, the surrounding liquid is attracted to the vicinity of the liquid discharge portion 31. That is, the liquid ejected from the liquid discharge part 31 proceeds in the direction of forming the active appearance part 35, and thus, a relatively low pressure is formed around the active appearance part 35. Therefore, the liquid around the active appearance portion 35 is sucked into the tip of the active appearance portion 35 by the pressure of the liquid discharged, and the liquid discharged and the liquid sucked into the tip of the active appearance portion 35 are evenly mixed, Again it is ejected through the end of the active appearance (35).

In this way, there is an advantage that many liquids around the multi-aeration stirrer A are evenly mixed by the active appearance part 35 formed to surround the external nozzle of the liquid discharge part 31. That is, to allow the liquid to be stirred in a larger amount than the amount of suction and discharge of the liquid for stirring in the liquid discharge part 31, so that a large amount of liquid around the liquid discharge part 31 flows together to be stirred. It is.

As described above, although described with reference to a preferred embodiment of the present invention, within the scope not departing from the spirit and scope of the present invention described in the claims by those skilled in the art In the present invention can be carried out by various modifications or variations.
