The traditional single blade agitator, its stirring blade usually presents propeller, although can promote the flow and mixing of fluid, but there is certain limitation in practical application. The stirring efficiency of single blade agitator is relatively low, especially when processing complex mixture, its performance is not satisfactory.

[0003] The traditional single blade agitator in liquid-liquid mixing process, due to the contact of blade's contact cutting process and the poor contact of liquid, lead to low heat transfer performance. This means that in the reaction process needing rapid heat transfer, the efficiency of single blade agitator cannot meet the requirements, thereby affecting the quality and production efficiency of product. In addition, when mixing solid-liquid, the stirring effect of single blade agitator is poor, leading to low liquid circulation rate, slow dissolution rate of solid material, and easy to produce the problem of solid material settlement. This phenomenon is particularly evident when processing high viscosity or large solid particle mixture, affecting the continuity of production.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. As long as the effect of the utility model can be achieved, various changes can be made to the implementation solutions.

[0023] By the personnel in the art, the parts in the case are sequentially connected, and the specific connection and operation sequence should be referred to the following working principle. The detailed connection means is the known technology in the art, and the following mainly introduces the working principle and process.

[0024] Reference Figures 1-3 The utility model discloses a wide single-leaf high-efficiency axial flow stirrer.

[0025] The existing wide single-leaf high-efficiency axial flow stirrer mainly comprises a hub 1 and a blade 3 connected through a blade root plate 2 around the circumference of the hub 1.

[0026] The difference between the embodiment and the above content is that: on the basis of the above content, the blade 3 comprises a blade root, a blade tip and a leading edge and a trailing edge connecting between the blade root and the blade tip, the blade root is fixed on the blade root plate 2, and the blade tip is a free end. Figure 1 As shown in the drawing, the blade 3 is sequentially formed with a front blade 31, a main blade 32, a connecting blade 33 and a rear blade 34 by continuously bending in the front edge to the trailing edge direction.

[0027] It should be noted that the bending of the front blade 31, the main blade 32, the connecting blade 33 and the rear blade 34 is continuous bending in one direction. The blade 3 is designed as a continuously bent structure, which has low shear performance and high discharge performance. When mixing liquid and liquid, the front blade 31, the main blade 32, the connecting blade 33 and the rear blade 34 formed by the multi-angle bending design can improve the heat exchange performance. When mixing solid and liquid, the front blade 31, the main blade 32, the connecting blade 33 and the rear blade 34 formed by the multi-angle bending design can stir the solid objects suspended in a large area, improve the circulation speed of the liquid after stirring, and further improve the dissolution speed of the solid material. The rear blade 34 can produce a stirring effect when rotating to prevent the solid from settling.

[0028] In one embodiment, the bending angles of the front blade 31, the main blade 32, the connecting blade 33, and the rear blade 34 are respectively:

[0029] The front blade 31 forms an angle α with the vertical line, where 10° < α < 20°, preferably 15°;

[0030] The angle β formed between the main blade 32 and the vertical line is 20° < β 30°, preferably 25°;

[0031] The angle γ between the connecting blade 33 and the vertical line is 40°<γ<50°, preferably 45°;

[0032] The rear blade 34 forms an angle η with the vertical line, where 50° < η < 65°, preferably 60°.

[0033] The angle between the front blade 31 and the main blade 32 is 170°. The angle between the main blade 32 and the connecting blade 33 is 160°. The angle between the connecting blade 33 and the rear blade 34 is 165°.

[0034] like Figure 3 As shown, to prevent the front blade 31, main blade 32 and rear blade 34 from changing angles during the stirring process, auxiliary connecting plates are formed on both sides of the part of the blade root plate 2 covering the blade 3. The auxiliary connecting plates cover the front blade 31, main blade 32 and rear blade 34, strengthen the use strength of the front blade 31, main blade 32 and rear blade 34, and prevent the front blade 31, main blade 32 or rear blade 34 from bending in the opposite direction when the blade 3 comes into contact with the liquid during use, which would cause the angle to change and affect the stirring effect.

[0035] Specifically, the auxiliary connecting plate includes a front guard plate 21, which includes a first extended guard plate 211 fixed to the front blade 31 and a second extended guard plate 212 fixed to the main blade 32. The first extended guard plate 211 is fitted with the front blade 31, and the second extended guard plate 212 is fitted with the main blade 32. The first extended guard plate 211 and the second extended guard plate 212 respectively fix the angle of the front blade 31 and the main blade 32. The auxiliary connecting plate also includes a rear guard plate 22 fixed to the rear blade 34. The rear guard plate 22 is fitted with the rear blade 34 and fixes the angle of the rear blade 34.
