1 to 4 are views for explaining the vortex mixer injection tube 10 according to an embodiment of the present invention, Figure 1 is a perspective view of the vortex mixer injection tube 10, Figure 2 is a vortex mixer powder FIG. 3 is an enlarged view of a portion in which the nozzle is installed to explain the spraying direction of each nozzle, and FIG. 4 is a fluid spraying direction of the nozzles provided in the vortex mixer spray pipe. It is a geometric perspective view for explaining. Here, FIG. 1 and FIG. 2 indicate the positions of the nozzles with respect to the virtual center point 13 by a dashed line, and FIG. 4 is for explaining the fluid injection direction, and shows only the positions of the nozzles without showing the nozzles and the injection pipes. It was.

1 to 4, the vortex mixer injection pipe 10 according to the embodiment of the present invention includes a hollow tube having one end 11 closed and the other end 12 opened as a virtual center point 13. It has a shape that is bent in a circular shape so as to circulate horizontally on the circumference, and the inner surface facing the imaginary center point 13 is provided with nozzles 14 provided at regular intervals along the circumferential direction.

That is, the injection pipe 10 is formed as an annular pipe open at one side with a circle around the imaginary center point 13 on a horizontal plane, and the injection direction of the nozzles 14 is surrounded by the injection pipe 10. It is directed inward, each nozzle 10 is in communication with the inner hollow of the injection tube 10, so that the fluid introduced into the inner hollow through the other end 12 opened inward through each nozzle 14 To be sprayed. In practice, the fluid is injected simultaneously from the nozzles 10 as the fluid is applied to the inner hollow of the injection pipe 10.

At this time, each nozzle 14, as shown in Figure 2, the injection direction is different in different directions depending on the position.

When the four nozzles 10: A, B, C, and D are connected to each other in a sequential order by arranging the nozzles 10 in a circumferential direction around the imaginary center point 13, along the circumferential direction Each pair is repeated sequentially. In detail, A, B, C, and D nozzles having different injection directions form a pair, and nozzles that form a pair in the order of A, B, C, and D nozzles are repeated along the circumferential direction.

)을 이루는 방향으로 틀어져 있고, 각 조의 노즐들 중에 1번째의 노즐인 A 노즐은 틀어지지 아니하고 상기 가상의 중심점(13)을 향하게 되어 있다. 여기서, A 노즐도 B,C,D 노즐과 동일하게 상기 예각(

)으로 틀어지게 할 수 있으나, 도 4를 참조하여 하술하는 바와 같이 상기 가상의 중심점을 향하게 하여서, B,C,D 노즐의 분사방향과의 각도를 크게 하고 B,C,D 노즐로부터 분사되는 유체가 상기 가상의 중심점으로 힘을 받게 하는 것이 좋다. 상기 예각에 의한 틀어짐 방향을 각 노즐에서 동일하게 하여 소용돌이를 위한 회전 흐름 방향도 동일하게 한다.The nozzles B, C, and D, which are the 2nd, 3rd, and 4th nozzles of each set of nozzles, have a direction toward a center point on a horizontal plane and a predetermined acute angle (

The nozzle No. A, which is the first nozzle of each set of nozzles, is not twisted and faces the virtual center point 13. Here, the A nozzle is also the acute angle (the same as the B, C, D nozzles)

), But the fluid is injected from the B, C, D nozzles to increase the angle to the injection direction of the B, C, D nozzles to face the virtual center point as described below with reference to FIG. It is good to force the virtual center point. The twisting direction by the acute angle is the same at each nozzle so that the rotational flow direction for the vortex is also the same.

On the other hand, in the specific embodiment of the present invention shown in the drawings, the end cap is mounted to close one end 11 of the injection pipe 10, the other end 12 is bent outward to inject fluid, Due to the space required for bending the closed end of the one end (11) and the other end (12), the C nozzle belonging to any one group was not installed. However, the above-described C nozzle may be provided by sufficiently reducing the space required for bending the closed end of the one end 11 and the other end 12. Here, the end cap is used to clean the interior after opening one end 11 of the injection pipe (10).

)로 방사상으로 뻗어 가는 가상의 선상에 배치되게 한다. 즉, 방사상으로 등각 배치, 즉, 인접하는 가상의 선 간의 각도가 동일하게 배치되게 하여서, 안쪽으로 분사되는 유체의 소용돌이가 어느 한쪽으로 편중되지 않게 한다. 여기서, 상기 등각도(

)는 상술한 바와 같이 A,B,C,D 노즐을 한 조로 하므로, 360°를 4의 배수로 나눈 각도이다. 이때, 상기 4의 배수는 16, 20, 24 및 28 중에 어느 하나로 하는 것이 바람직하다. 이는, 28보가 큰 4의 배수로 하면 노즐 간의 간격이 너무 작아 필요 이상으로 노즐의 개수가 많아지고, 16보다 작은 4의 배수로 하면 노즐 간의 간격이 너무 커져서 후술하는 바와 같이 A 노즐로 분사한 유체의 흐름이 B,C,D 노즐로 분사한 유체 흐름에 미치는 영향이 미약해지기 때문이다.The nozzles 10: A, B, C, and D are equiangular at the imaginary center point.

) To be placed on a virtual line extending radially. That is, the radially conformal arrangement, that is, the angle between adjacent imaginary lines are arranged equally, so that the vortex of the fluid injected inward is not biased to either side. Where the isometric angle (

) Is an angle obtained by dividing 360 ° by a multiple of 4 because A, B, C, and D nozzles are a group as described above. At this time, the multiple of 4 is preferably any one of 16, 20, 24 and 28. This means that when the multiple of 4 is 28, the interval between the nozzles is too small and the number of nozzles is larger than necessary, and when the multiple of 4 is smaller than 16, the interval between the nozzles is too large, so that the flow of the fluid injected into the nozzle A will be described later. This is because the influence on the fluid flow injected by the B, C, and D nozzles is reduced.

)만큼 하향지게 하고, 각 조의 D 노즐은 수평면을 기준으로 상향으로 유체를 분사하도록 노즐의 분사 방향을 수평면에 대해 상향 경사각(

)만큼 상향지게 한다.In addition, the B nozzles of the pairs have a downward inclination angle with respect to the horizontal plane to inject the fluid downward with respect to the horizontal plane.

), And each nozzle of D sets the direction of inclination of the nozzle upwardly with respect to the horizontal plane to eject the fluid upward with respect to the horizontal plane.

Up by).

As shown in FIG. 3, the spraying direction of the A, B, C, and D nozzles belonging to each group is directed to the imaginary center point 13, and the spraying direction of the B nozzle is on the horizontal plane. The direction inclined by the acute angle with respect to the direction toward the virtual center point 13 and at the same time inclined downward by the downward inclination angle with respect to the vertical plane, the spraying direction of the C nozzle is the virtual center point 13 on the horizontal plane ) And toward the direction twisted by the acute angle, but not inclined on the vertical plane, and the spraying direction of the D nozzle is directed toward the virtual center point 13 on the horizontal plane and in the direction twisted by the acute angle and simultaneously on the vertical plane. It is inclined upward by the upward inclination angle with respect to the direction.

In summary, nozzles are arranged at an equiangular position on an imaginary circle 13d centered on the imaginary center point 13, and a plurality of sets of A, B, C, and D nozzles as a pair are arranged in the virtual center point. (13) is arranged in a circumferential manner, and if a pair of A nozzles is used as the first nozzle and the order is given along the circumferential direction, the even-numbered nozzles (B nozzles and D nozzles in each pair) The spraying direction is alternately downward and upward. That is, every even number of nozzles (B nozzles and D nozzles in each pair) are lowered to the downward inclination angle one by one, and the other is upward to the upward inclination angle.

Then, the nozzles are turned in the direction of forming the acute angle with respect to the direction of the virtual center point 13 on the horizontal plane, one of the nozzles (each set of A, D nozzles) arranged in an odd number along the circumferential direction Only every other nozzle selected (A nozzles in each pair) is directed to the virtual center point without changing the direction on the horizontal plane.

Accordingly, as shown in Figure 4 in the injection pipe 10 according to the present invention, the injection direction of the A, B, C, D nozzles belonging to each tank is different from each other, the lower end of the injection pipe 10 is cylindrical When installed on the inner bottom of the stirrer, the fluid injected from the B, C, D nozzle twisted at an acute angle on the horizontal plane vortex. Specifically, it swirls upward as the fluid is injected from the upwardly inclined D nozzle. As the fluid is injected from the downwardly inclined B nozzle, the fluid near the bottom surface of the stirrer is raised while causing the same rotational flow as the rotational flow direction of the vortex by the D nozzle to increase the stirring effect. Since the flow of the fluid injected from the C nozzle is a horizontal rotational flow, only the rotational force is applied to the rising and swirling flow by the B nozzle to increase the stirring effect.

Further, the A nozzle does not cause rotational flow since it causes the fluid flow toward the imaginary center point, whereas the angle between the B, C, and D nozzles is the angle between the B, C, and D nozzles. Since it is relatively larger, it acts to impact the vortex flow by the B, C, D nozzles. Accordingly, an improved stirring effect can be obtained than the stirring effect of only the vortex, and also serves to pulverize the lumped heterogeneous material moving along the rotation flow of the vortex.

)은 10°내지 20°의 범위 내에서 정하는 것이 바람직하다. 이는, 도 3에 도시한 바와 같이, 노즐들의 분사방향이 공통으로 접선방향이 되는 가상의 원(13a, 13b, 13c)의 지름이 적당한 크기여야만 분사한 유체의 흐름에 의한 소용돌이가 본 발명이 원하는 형태로 잘 일어나기 때문이다. 즉, 상술한 바와 도 4에 도시한 바에 따르면, 하향의 분사방향을 갖는 B 노즐의 분사방향이 접선이 되는 하부의 가상의 원(13c), 상향의 분사방향을 갖는 D 노즐의 분사방향이 접선이 되는 상부의 가상의 원(13a), 및 수평면상의 분사방향을 갖는 C 노즐의 분사방향이 접선이 되는 중간의 가상의 원(13b)이 분사관(10)으로 에워싸인 내측에 상기 가상의 중심점을 중심으로 형성되는 데, 이때, 상기 예각을 크게 하면 소용돌이(또는 와류) 발생을 위한 회전 흐름을 크게 할 수 있으나, 상기 가상의 원의 직경이 커져서 교반기의 바닥 중심에 가해지는 회전 흐름이 약해진다. 이에 따라, 교반기의 바닥 중심에 쌓이는 덩어리진 물질에 가해지는 충격이 약해지고, 결국 교반 효과가 낮아진다. On the other hand, the acute angle (

) Is preferably set within the range of 10 ° to 20 °. 3, the vortex due to the flow of the injected fluid only when the diameter of the imaginary circles 13a, 13b, and 13c, in which the nozzles are commonly tangential, has a proper diameter, as shown in FIG. Because it happens well in the form you want. That is, as described above and as shown in Fig. 4, the imaginary circle 13c of the lower portion where the spraying direction of the B nozzle having the downward spraying direction is tangential and the spraying direction of the D nozzle having the upward spraying direction are tangential. The virtual center 13a of the upper part which becomes the upper part, and the virtual center 13b of the intermediate | middle virtual circle 13b which the injection direction of the C nozzle which has the injection direction on a horizontal plane are tangentially surrounded by the injection pipe | tube 10 is the said virtual center point. In this case, when the acute angle is increased, the rotational flow for vortex (or vortex) can be increased, but the diameter of the imaginary circle is increased to weaken the rotational flow applied to the bottom center of the stirrer. . As a result, the impact applied to the lumped material accumulated at the bottom center of the stirrer is weakened, and the stirring effect is lowered.

)은 10°내지 20°의 범위 내로 할 경우, 교반 효과가 크게 나타남을 확인할 수 있었다. 이러한 교반 효과는, 본 발명에 따른 분사관(10)을 하기의 교반기(20)에 사용하여 황토를 물에 섞었을 때에, 교반기(20)의 바닥에 쌓이는 덩어리진 황토의 양이 상대적으로 많이 줄어드는 것을 보면 알 수 있는 것이다. 실제 실험 제품으로 만들었을 때에는 상기 등각도(

)를 15°로 하고, 상기 예각(

)도 15°로 하였다.As a result of repeated experiments taking into account the diameter of the imaginary circle 13d where the nozzles are located and the diameter of the inner imaginary circle 13a, 13b, 13c where the spray directions of the B, C, and D nozzles are tangent, The acute angle (

In the case of) within the range of 10 ° to 20 °, it was confirmed that the stirring effect is large. This agitation effect is that when the ocher is mixed with water by using the injection pipe 10 according to the present invention to the stirrer 20 described below, the amount of agglomerated loess accumulated at the bottom of the stirrer 20 is relatively reduced. You can see it. When made into a real experimental product,

) 15 ° and the acute angle (

) Was also 15 °.

) 및 D 노즐의 상향 경사각(

)은 분사관(10)을 교반기(20)의 내부 바닥에 설치하였을 때에, 유체가 부상하면서 가능하면 많은 회전수로 소용돌이치고, 더불어, 노즐에서 분사된 유체의 유량에 의한 부상력보다 노즐에서의 분사에 따른 흐름에 의해 상향류가 발생하도록 적절하게 선정하여야 하며, 이에 따르면, 3° 내지 12°의 범위 내에 있는 각도로 선정하는 것이 적절함을 확인하였다. 예를 들어, 황토를 물에 섞는 과정에서 덩어리진 황토가 소용돌이 및 상승류에 의에 상승하면서 분쇄되는 것을 보면 확인 가능하다. 즉, 상기 하향 경사각(

) 및 상향 경사각(

)을 3°미만으로 하면 상승류가 약해서 덩어리진 황토가 잘 부상하지 않고 미립자로 분쇄되지도 않으며, 12°보다 클 경우 덩어리진 황토가 부상은 잘 되지만 너무 빠르게 부상하여 와류에 의한 분쇄가 잘 일어나지 않는다. 실제 실험 제품으로 만들었을 때에는 상기 하향 경사각(

)을 동일하게 5°로 하였다.
On the other hand, the downward inclination angle of the B nozzle (

) And the upward tilt angle of the D nozzle (

When the injection pipe 10 is installed on the inner bottom of the stirrer 20, the fluid floats and swirls at as many revolutions as possible, and the pressure rises at the nozzle rather than the lift force due to the flow rate of the fluid injected from the nozzle. It should be appropriately selected so that the upstream is generated by the flow according to the injection, and accordingly, it was confirmed that it is appropriate to select at an angle within the range of 3 ° to 12 °. For example, in the process of mixing ocher with water, it can be confirmed that the agglomerated loess is crushed while rising due to swirling and upward flow. That is, the downward tilt angle (

) And upward tilt angle (

) If it is less than 3 °, the rising flow is weak, so the agglomerated ocher is not easily injured and pulverized into fine particles.If it is larger than 12 °, the agglomerated ocher is well injured, but it is injured too quickly to cause pulverization by vortex. Do not. When made into a real experimental product, the downward tilt angle (

) And upward tilt angle (

) Was similarly set to 5 °.

The suspension contained in it can be drained by opening the drain valve 48.

The hopper 30 allows to hold a sufficient amount of the ocher suspension in order to continuously spray the ocher suspension through the spray pipe 49.

As described above, the vortex mixer-type ocher sprayer, as described above, injects raw water from the stirrer 20 to the vortex mixer injection tube 10 while internally injecting the ocher particles through the upper opening to finely granulate the raw water. Since the fine particles of raw soil and raw water are mixed well, the resulting suspension flows into the hopper 30 through the flow path 31, so that the suspension contained in the hopper 30 is uniformly mixed as fine particles without lump loess. Becomes Accordingly, by spraying the ocher suspension sprayed with the ocher sprayer according to the present invention can increase the prevention and removal effect of the green alga or red tide.
