【発明が解決しようとする課題】この従来の撹拌翼によ
れば、その回転により単板翼の回転方向における後端部
の上面に渦の発生に伴う液体の剥離が生じ、この剥離に
より液体の循環速度が小となって撹拌効率が低下する問
題点があった。According to the conventional stirring blade, the rotation causes the liquid to separate due to the generation of a vortex on the upper surface of the rear end portion in the rotation direction of the single-plate blade. There was a problem that the circulation speed was reduced and the stirring efficiency was reduced.
【０００４】本発明はこのような問題点を解消し、簡単

ることを特徴とする。In order to achieve this object, according to the present invention, a wing unit protruding from a boss has one plate-like shape which is inclined in the rotational direction and is disposed vertically above and below each other. It is characterized by comprising a wing body and another plate-shaped separation preventing wing body for eliminating or reducing the separation caused by the eddy current of the liquid generated at the rear end of the wing body.

【実施例】本発明の撹拌翼の第１実施例を図１乃至図３
に従って説明する。1 to 3 show a first embodiment of a stirring blade according to the present invention.
It will be described according to.

体２ａ、２ｂ間の間隔を保持するための支持片を示す。Reference numeral 1 denotes a boss, 2... 2 denote wing units radially protruding from the outer periphery of the boss 1, and each of these wing units 2.
Consists of a main wing body 2a as one wing body and an auxiliary wing body 2b as another wing body for preventing separation.
a and the other auxiliary wing body 2b are formed of band-shaped plates at a predetermined interval from each other, and are both formed to be inclined in the rotational direction such that the front end is upward and the rear end is downward. Reference numeral 3 denotes a support piece for maintaining an interval between the two wing bodies 2a and 2b.

となり、撹拌が円滑に行われる。When the boss 1 of the stirring blade is fixed to the lower end of the rotating shaft, and the stirring blade is rotated in the liquid in the direction of the arrow in FIG. 1, the main wing body 2a as shown in FIG. A liquid flow such as B is generated by the auxiliary wing body 2b while the liquid flow is generated, and the liquid flow B causes the liquid at a position above the rear end of the main wing body 2a generated in the case of the conventional stirring blade. The separation phenomenon due to the vortex disappears or decreases, and thus the flow velocity and the flow rate are increased at the top and bottom of the main wing body 2a, and the stirring is smoothly performed.

よい。In this embodiment, an example in which two upper and lower wings are provided has been described. However, three or more wings may be provided at an interval from each other as necessary. Alternatively, the rear end may be inclined so that the front end is downward and the rear end is upward in the rotation direction.

In this embodiment, an auxiliary wing body 2b for preventing peeling which is located at an upper portion is formed in a shape of a letter which is bent in the middle. Thus, according to the rotation of the stirring blade in the liquid, the flow B above the main wing body 2a is bent by the rear part 2c in which the inclination of the auxiliary wing body 2b is steep, and the flow B is formed on the upper surface of the rear part of the main wing body 2a. In the same manner as in the first embodiment, the fluid flows positively along the edge of the main wing body 2a, so that separation of the liquid above the rear end of the main wing body 2a due to the vortex is more reliably prevented, and rectification is performed above and below the main wing body 2a. As a result, the speed and the flow rate become large, and further, even above the auxiliary wing body 2b, the rear part 2c is steeply inclined downward, so that a negative pressure part is formed above the auxiliary wing body 2b and the liquid flow C is bent. The speed and flow rate are greatly rectified without separation and separation and agitation Rate becomes larger.

d and the rear portion 2e are steeply inclined, and the separation preventing auxiliary wing 2b is also formed so that the rear portion 2f is steeply inclined, and the auxiliary wing 2b is provided below the main wing 2a with an interval. The liquid flow B is separated above the main wing body 2a in the same manner as the auxiliary wing body 2b of the second embodiment because the front part 2d and the rear part 2e of the main wing body 2a are steeply inclined. Rectification of high velocity without flow, and flow rectification of high velocity and high flow rate above the auxiliary wing 2b without separation due to the flow A bent by the steep inclination of the rear part 2e of the main wing 2a. All of the flows A and B together with the flow D below the auxiliary wing body 2b are rectified at a high speed and a high flow rate, and the stirring efficiency is increased.

In this embodiment, auxiliary wings 2b and 2g for preventing separation are provided above and below the main wing 2a. Thus, the overall flow of the liquid is a rectified state in which the flows of the second and third embodiments are combined, and the stirring efficiency is large.
