Hereinafter, a preferred embodiment of the water treatment stirring apparatus according to the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

In the description of the present invention, terms defined are defined in consideration of functions in the present invention, which may vary according to the intention or custom of a person skilled in the art and the definitions are based on the contents throughout this specification. Will have to be lowered.

Figure 2 is a perspective view showing for explaining the water treatment stirring apparatus according to an embodiment of the present invention.

As shown in FIG. 9, the stirring apparatus 100 of the present invention has a separate structure in the outdoor space such as a river, a reservoir, a river or the sea as well as a water treatment plant as shown in FIG. 9 through the buoyancy

adjustable floats

117 and 138. It can be installed without, of course, there is an advantage that can be cleaned for a wide range.

The stirring device 100 drives the inlet 160 to suck the foreign matter precipitated in the bottom of the water body, the discharge 130 to discharge the introduced foreign matter into the upper water layer and the impeller 115 to water the foreign matter. It is largely configured as a driving unit 110 for pulling up from the lower layer to the upper layer, which will be described in detail with reference to FIGS. 3 and 4.

3 is an exploded perspective view illustrating a stirring device according to an embodiment of the present invention, Figure 4 is a cross-sectional view of the stirring device.

As shown in FIG. 3, the stirring device 100 is largely composed of an inlet 160, an outlet 130, and a driver 110.

Inlet 160 is a tubular shape immersed vertically in the water body, the inlet 165 through which the foreign matter precipitated in the bottom of the water through the rotation of the impeller 115 and the inlet for inducing the sucked foreign matter into the upper body of the water body. The secondary body 161 and the inlet body 161 and the second flange 163 for coupling the outlet 130 is composed.

The inlet 160 is a tubular body diffused downward, and further includes a support 169 for predetermined distance from the bottom surface of the inlet 165 facing the water surface.

Here, the support 169 is to facilitate the suction of foreign matter by the predetermined distance from the inlet 165 and the bottom surface, or to maintain a spaced state of the inlet 165 and the bottom surface, the inlet body 161 It may also be used to limit the movement of a).

That is, by fixing the support 169 to the bottom surface it is possible to limit the inlet body 161 to move from the current position even at the flow rate.

For example, when the stirring device 100 is installed outdoors, and the inlet body 161 is not fixed, the stirring device 100 is separated from the installed place through the discharge amount discharged from the reservoir or the dam, or the flow rate due to the difference between tides. Problems may arise.

This is because the risk of loss from the contaminated area may occur, and above all, there is a big problem that the water quality improvement of the contaminated area cannot be made.

Therefore, especially when the stirring device 100 is installed outdoors it is necessary to be fixed, which is preferably fixed through the support (169).

In addition, the inlet body 161 is a body that is vertically immersed in the body of water, and the corrugated portion 167 is formed to be stretchable, to induce an upward flow of foreign matter sucked through the inlet 165.

In this case, the inlet body 161 is preferably a tubular body as shown, but should not be limited to this, and very preferably may be in the form of a polygon of various shapes such as square, pentagon and hexagon, as well as the cylinder. .

On the other hand, the wrinkles 167 is to adjust the length of the inlet body 161, when the depth of the deepening or lowering according to the change in the water level, to maintain the corresponding length.

In particular, in the case of an outdoor area such as a river, a reservoir, a river or the sea, a periodic change in depth occurs due to the amount of discharge of water or the difference between tides.

Therefore, the wrinkle portion 167 needs to be made to extend or shorten the length of the inlet body 161 in response to the change in depth.

The discharge unit 130 is provided with a first flange 149 to be discharged and discharged to the upper portion of the body of the discharge body 131 and the second body 131 is tightly coupled to the upper portion of the water inlet 160. And a second floatation unit 138 for adjusting the balance of the diffusion unit 135 and the stirring device 100 installed in the water and the discharge area of the foreign matter.

The discharge part body 131 has a tubular shape and is provided with a second bracket 147 for fastening the driving unit 110 on one side of the outer circumferential surface thereof, and a guide member for supporting the rotation shaft of the impeller 116 in one region of the inner circumferential surface thereof. 133 is provided.

The second bracket 147 is integrally provided through the discharge unit body 131 and the fastening means, and is detachably coupled to the first bracket 119 of the driving unit 110, and the driving unit together with the first bracket 119. It is to couple the 110 to a predetermined distance.

As illustrated in FIG. 4, the guide member 133 supports the rotating shaft 113 that is rotated by the driving of the motor 111, so that the rotating shaft 113 is eccentric or rotates together with the rotating shaft 113. ) Is to be prevented from being damaged with the rotation shaft 113 by the eccentricity.

Diffusion unit 135 is a form that is extended to the upper portion of the discharge unit body 131, that is, a dish, is to diffuse and discharge the foreign matter sucked from the bottom of the water body to the upper water layer.

In addition, the diffusion unit 135 is further formed with a diffusion protrusion 137 for guiding the diffusion of foreign matter discharged to the upper water layer, the diffusion protrusion 137 is provided in a spiral shape to induce the diffusion of the foreign matter, as well as the upper water layer It is to maximize the spread of foreign substances discharged into the.

The second floating part 138 is provided in at least one pair on the other side of the outer peripheral surface of the discharge part body 131, and adjusts the buoyancy of the stirring device 100 in the water body, so that the overall balance of the device and the diffusion part 135 To adjust the height.

The second floating part 138 has a cylindrical shape with an empty inside, and is integrally installed in close contact with the discharge part body 131 through the second support 141 as shown.

This is to facilitate the installation and installation in a narrow area, such as a stirring tank (not shown), as well as a compact volume.

For example, when the second floating part 138 is spaced apart from the discharge body 131, the volume may not be easily loaded due to its volume, and the second floating part 138 may be disposed with the discharge body 131. The hassle of transporting separately and the economic loss caused by the increase of freight cost are incurred, and above all, the installation and the separation of them from the site must be assembled, and the work environment has to be done in the water, so assembly and installation are not easy. .

Therefore, the second floating part 138 is integrally installed to the discharge part body 131 in one piece, so that the device may be manufactured in a compact manner, as well as easy to carry and install.

At this time, the second floating part 138 is installed integrally with the discharge part body 131, it is preferable that the second type is detachable through a fastening means such as a bolt.

On the other hand, it is preferable that the inlet 143 for injecting the fluid into the second floating portion 138 and the inlet cap 145 for opening and closing the buoyancy control is possible.

As such, it is to adjust the height of the diffusion unit 135 through the buoyancy control, and to perform a good stirring operation through the ascending water flow action to float and circulate the foreign matter precipitated in the bottom of the body of water.

For example, when the diffusion unit 135 rises above the surface of the water, foreign substances in the bottom of the water can be suspended above the surface of the water, but the circulation due to the upward flow cannot be made, and the diffusion unit 135 is located in the middle of the water surface. There is a problem that stirring is performed only in the water basin and the middle layer.

Therefore, while the diffusion unit 135 is immersed below the surface of the water, the buoyancy of the second floating portion 138 should be adjusted to maintain sufficient proximity to the water surface so that sufficient agitation can be achieved in the bottom and the upper portion of the water. Buoyancy control at 135 is of paramount importance in water treatment operations.

In addition, the second floating portion 138 is composed of an integral structure that can be separated from the discharge body 131, away from the conventional limited installation area, the present invention is a water treatment plant, as well as a river, reservoir, river or sea There is a big structural feature that can be installed in the open air without a separate structure.

On the other hand, in case it is necessary to withdraw the fluid injected into the second floating portion 138, or to reduce the amount of fluid, although not shown, a drain (not shown) may be further provided.

Such a discharge port is preferably formed at the lower side of the side of the second floating portion, or is formed at the bottom.

In addition, it is preferable that the second floating portion 138 is at least one pair, and may have a fan shape as shown in the figure, or a ring shape as shown in FIG. 6, depending on the installation environment or overall balance of the device. It can be selectively employed.

For example, if the configuration of the stirring device (not shown, for example, a bubble device and a device for drug input, etc.) is installed in one direction in one direction, the center of gravity is biased to either side, as shown By varying the amount of the fluid accommodated in each of the second floating portion 138 facing each other, the overall center of gravity of the stirring device 100 is maintained to maintain a stable floating in the water body.

That is, a small amount or fluid is not injected into the second floating part 138 on one side of which weight is biased, and a corresponding amount of fluid is injected into the second floating part 138 on the other side so that the balance of weight is maintained. By doing so, the overall balance of the stirring device 100, as well as the buoyancy can be adjusted.

On the other hand, the stirring device 100 by the buoyancy control of the second floating part 138 maintains a stable state in the water, but as the exposure to nature, such as agitation depending on the speed of the wind or water current and variable water level ( 100) may be biased or flooded into the water.

That is, the stirring device 100 is unbalanced in one direction due to changes in water flow, or the fluid of the second floating part 138 is generated inside, due to an unstable floating state, and furthermore, the second floating part 138 A) the inner side is biased to one side, and the agitation apparatus 100 may be heavily flooded into the water, especially in the case of the sea, due to the difference between the waves or tides, as well as the possibility of being inundated into the water It is.

Accordingly, as shown in FIG. 5, the total receiving area of the fluid is maintained, but the durable space is partitioned by the partition wall 139 to minimize the flow of the fluid in the second floating part 138, which is illustrated in FIG. 5. This will be described with reference to.

5 is a plan view and a cross-sectional view showing a second floating part according to an embodiment of the present invention to illustrate an example. Here, (a) shows the case where two second floating parts are provided, (b) shows the case where three second floating parts are provided, and (c) is divided into three areas using two partition walls. The cross section of each 2nd floating part is shown. The number of the second floatation portions may be greater than that as long as each second floatation portion is positioned in a region partitioned evenly. In FIG. 5, one second floating part is provided in each of the two divided areas that are uniformly divided, and one second floating part is provided in each of the three divided areas that are uniformly divided.

As shown, the partition wall 139 is further installed in each of the second floating parts 138 and partitioned into at least one or more areas, thereby maintaining the entire inner area, and partitioning the inside of the second floating part 138 to allow the fluid to flow in the stirring device 100. Even if it is moved or biased, it is possible to minimize the phenomenon that the inner fluid of the second floating part 138 is swung or biased.

That is, since the area of each space partitioned by the partition wall 139 is reduced, it is possible to minimize the flow movement of the fluid contained in each space, it is possible to stabilize the overall balance of the stirring device (100).

The partition wall 139 may partition the inner space of the second floating portion 138 in various forms. As shown in one embodiment, the partition wall 139 receives the fluid in preference to only the partitioned space. The fluid is not accommodated in two spaces so that buoyancy is maintained by the space in which the fluid is not accommodated, and thus the agitating apparatus 100 is accommodated in one second floating portion 138 that is not partitioned. Can be prevented from sharply inclined, and the balance can be maintained. It also has the advantage of being very easy to balance buoyancy. In this regard, the present invention achieves another important feature.

In addition, the partition wall 139 is formed of at least a first region 138-1 and a second region 138-2 at equal intervals, such as a cross-sectional view cut along S1 of the second floating portion 138. It may be partitioned into three regions 138-3, or at least two or more regions at predetermined intervals.

On the other hand, if the center of gravity of the stirring device 100 is good, as shown in Figure 6 showing another example of the second floating portion 138 can be applied to adjust the buoyancy of the stirring device 100.

That is, since the center of gravity of the stirring device 100 is good and the fluid accommodated in the second floating part 138 maintains a horizontal state, it is possible to maintain a stable floating state.

Meanwhile, the second floating part 138 may be connected through the fluid communication tube 151 as shown in FIG. 7, which is referred to in FIGS. 7 and 8 showing another example of the second floating part 138. To explain.

Although the fluid communication tube 151 connects at least one pair of second floating parts 138 to inject fluid into at least one second floating part 138, the other one or more second floating parts are shown. (138) is connected to the pipe connected.

That is, as shown in FIG. 7, after the injection port cap 145 is removed from any one second floating part 138, when the fluid is introduced into the injection port 143, the fluid flows into the communication port 153. The introduced fluid is to fill the fluid into another second floating part 138 through the fluid communication tube 151.

Accordingly, each second floating portion 138 may be horizontally maintained with each other, and the height of the stirring device 100 and the diffusion part 135 may be balanced in a balanced manner.

Meanwhile, as illustrated in FIGS. 2 to 4, the driving unit 110 includes an impeller 116 that rotates by receiving a rotational force of the motor 111 through the rotation shaft 113, and the driving unit 110 including at least the motor 111. The first floating portion 117 is prevented from being immersed, the driving unit 110 is coupled to the second bracket 147, the first bracket 119 for coupling to the diffusion portion 135 spaced apart It is configured to include.

Impeller 116 is installed as the inner circumferential region of the discharge unit 130, as shown in order to rotate in one direction so that foreign matter in the bottom of the water can be easily discharged through the diffuser 135 of the upper water layer through the inlet port It is for.

However, the installation area of the impeller 116 should not be limited to the area shown, which is to maximize the suction force through the inlet 165 and the discharge force through the diffusion unit (eg, inflow) Part, the discharge part and any one of the areas therebetween).

The first floating part 117 is for preventing the driving unit 110 from being immersed in the water body, and as shown in FIG. 4, the first floating part 117 has a hollow shape.

The first floating part 117 is installed below the motor 111 through the first bracket 119, but is preferably installed at a predetermined distance from the motor 111 through the first support 121, which is water surface. It is possible to prevent the at least the motor 111 is immersed by allowing the distance to and further apart.

In addition, even if the second floating part 138 is damaged and the entire apparatus is immersed in the water, at least the motor 111 can be prevented from being immersed or wetted by the first floating part 117. It is.

On the other hand, the motor 111 is preferably installed in the panel 123 supported through the first bracket 119.

Although the panel 123 is not shown, a power source for driving the motor 111 and a control unit for controlling the same are installed, and when the stirring device 100 is installed or when maintenance is required later, a work space is provided. It is intended to be used as an area to provide.

At this time, the power source is preferably a solar cell or an AC power source, which is preferably applied selectively according to the region in which the stirring device 100 is installed.

In the stirring device 100 according to the present invention, as shown in FIG. 9, the foreign substances sucked through the inlet 160 are diffused and discharged into the upper layer of the water through the diffuser 135 and through the upward water flow action. By maintaining the suspended state of the foreign matter by circulating the foreign matter up and down from the bottom of the water to the upper part of the water, the excellent water purification work is performed by removing the foreign matter and smooth stirring with the chemicals added according to the contaminated state. The present invention can be easily installed in the outdoors, such as rivers, reservoirs, rivers or the sea without a separate structure.
