본 고안은 상기와 같은 상하 대류현상이 효과적으로 이루어지도록 하기 위하여, 제 2도에 도시한 바와 같이 혼합용기(1)의 상·중·하 위치에 따라 날개판(2)의 경사각θ와 보조날개(10)의 결착위치를 각각 달리 형성시킨 것으로, 이것을 각각 설명하면, 상부의 교반날개(B)는 날개면(3)과 회전축(4)간의 경사각 θ를 θ0로 유지하되 상기 날개판(2)의 상단이 진행 방향쪽으로 기울어져 있어, 날개판(2)이 회전될 때 전방쪽 날개면(3)에 맞닿는액상물(13)이 날개면(3)을따라 하방향으로 미끄러져 유동되고, 상기 액상물(13)의 일부는 유입구멍(8)을 통해 후방쪽 날개면3)상부에 결착된 보조날개(10)의 와류 유도면(12)을 따라 유입된 후 개방부(11)와 유출간극(d)을 통해 유출되므로써 하방향으로 와류가 이어질 수 있도록 하는 한편, 하부의 교반날개(B)는 날개면(3)과 회전축(4)간의 경사각θ를 θ0로 유지하되 상기 날개판(2)의 하단이 진행 방향쪽으로 기울어져 있어, 날개판(2)이 회전될 때 전방쪽 날개면(3)에 맞닿는 액상물(13)이 날개면(3)을 따라 상승되고, 상기 액상물(13)의 일부는 유입구멍(8)을 통해 후방쪽 날개면(3)하부에 결착된 보조날개(10)의 와류 유도면(12)을 따라 유입된 후 개방부(11)와 유출간극(d)을 통해 유출되므로써 상방향으로 와류가 이어 질수 있도록 한 것이며, 또한 중간의 교반날개(B)는 날개면(3)의 방향을 회전축(4)의 방향과 동일하게 하여, 날개판(2)이 회전될 때 상.하로부터 와류 이동된 액상물(13)이 날개판(2)에 의해 골고루 교반되고, 상기 액상물(13)의 일부는 유입구멍(8)을 통해 후방쪽 날개면(3) 상부에 결착된 보조날개(10)의 와류 유도면(12)을따라 유입된 후 개방부(11)와 유출간극(d)을 통해 재 유출되므로써 전체적으로 상하 대류가 원활히 이루어질 수 있도록 한 것이다.In order to effectively achieve the above-described up and down convection, the present invention, as shown in Figure 2 according to the upper, middle, lower position of the mixing vessel (1) inclination angle θ and auxiliary wings ( 10, the binding position of each is formed differently, each of which will be described, the upper stirring blade (B) is to maintain the inclination angle θ between the wing surface 3 and the rotating shaft (4) at θ0 of the wing plate (2) The upper end is inclined toward the traveling direction, and when the vane plate 2 is rotated, the liquid substance 13 which abuts on the front vane plane 3 slides downward along the vane plane 3, and flows, A portion of the water 13 is introduced along the vortex guide surface 12 of the auxiliary wing 10, which is fastened to the rear wing surface 3 through the inlet hole 8, and then the opening 11 and the outlet gap ( While flowing through the d) so that the vortex can continue in the downward direction, while the lower stirring blade (B) is the wing surface (3) and the rotating shaft The inclination angle θ between (4) is maintained at θ0, but the lower end of the wing plate 2 is inclined toward the traveling direction, so that the liquid substance 13 abuts on the front wing surface 3 when the wing plate 2 is rotated. The vortex guide surface 12 of the auxiliary wing 10 is raised along the wing surface 3, and a part of the liquid substance 13 is attached to the lower side of the rear wing surface 3 through the inlet hole (8). After flowing along the flow through the opening 11 and the outlet gap (d) so that the vortex can continue in the upward direction, and the middle stirring blade (B) in the direction of the wing surface (3) the axis of rotation ( In the same manner as in 4), when the vane 2 is rotated, the liquid 13 vortexed from the upper and lower sides is evenly stirred by the vane 2, and a part of the liquid 13 is rotated. Is introduced along the vortex guiding surface 12 of the auxiliary blade 10 attached to the upper side of the rear wing surface (3) through the inlet hole (8) and then re-opened through the opening (11) and the outlet gap (d). Spilled Write it down a whole, so that convection can take place smoothly.

이때, 보조날개(10)는 날개판(2)의 크기와 교반효율을 고려하여 적정한 갯수로 전연쪽에 다수개 결착하되, 보조날개의 가로폭(W1)을 유입구멍의 가로폭(W2)보다 다소 크게 설정하고, 보조날개의 세로폭(W3)도 유입구멍의 세로폭(W4)보다 다소 크게 설정하는 것이 와류를 유도하기에 적합하며, 점도가 높은 액상물(13)일수록 축방향에 대해 날개판(2)의 경사각θ을 크게 하므로써 유체저항을 줄일 수 있다.At this time, the auxiliary wing 10 is bound to the leading edge in the appropriate number in consideration of the size and agitation efficiency of the wing plate (2), the width of the auxiliary wing (W 1 ) the width of the inlet hole (W 2 ) It is suitable to induce vortex, and to set slightly larger, and set the longitudinal width W 3 of the auxiliary wing to be slightly larger than the vertical width W 4 of the inlet hole. The fluid resistance can be reduced by increasing the inclination angle θ of the blade plate 2 with respect to.

따라서, 단순히 평면상으로 이루어진 종래의 교반날개(B)에 비해, 본 고안은 날개의 구조를 개량하므로써 단시간 내에 균일한 밀도로 액상물(13)을 교반시켜 줄 수 있고, 적은 동력으로도 효과적으로 다향한 점도의 액상물(13)을 혼합시켜 줄 수 있는 매우 유용한 고안인 것이다.Therefore, compared to the conventional stirring blade (B) simply made in a flat plane, the present invention can stir the liquid (13) in a uniform density within a short time by improving the structure of the blade, and effectively multi-directional even with less power It is a very useful design that can mix the liquid 13 of one viscosity.
