Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0033] Referring to Figure 1 The utility model provides technical scheme: a single wing plate shape runoff type impeller, it includes: shaft 1, the outer wing plate 2 is provided on the shaft 1, and the shaft 1 is used to be connected with driving device, and driving device provides power for the rotation of outer wing plate 2;Multiple toothed plates 3 are arranged on the outer wing plate 2 away from the shaft, and the outer wing plate 2 is used to stir high viscosity fluid.
[0034] Among them, the shaft 1 is preferably a cylindrical structure, for example, a cylinder or a polygonal column. One end of the shaft 1 is connected with the rotating shaft of the driving device along the length direction of the rotating shaft, so that when the rotating shaft of the driving device rotates, the shaft 1 rotates along its length direction, driving the outer wing plate 2 to rotate around the vertical axis direction of the shaft 1. The toothed plate 3 is detachably mounted on the outer wing plate 2, which is convenient for maintenance, replacement and maintenance of the toothed plate 3 after stirring is completed.
[0035] When the outer wing plate 2 rotates, the radial flow capacity is provided for the high viscosity liquid in the stirring tank, and the laminar flow area is generated near the outer wing plate 2, which has a good effect on mixing the high viscosity liquid. The plurality of tooth plates 3 on the outer wing plate 2 can shear the liquid units in the high viscosity liquid in the laminar flow area, and the laminar flow area can be destroyed through the axial sweeping, so that the shear field in the stirring tank is more uniform, and the liquid units in the high viscosity liquid are gradually elongated, thinned or divided through the shearing and subdividing effect, so that the purposes of mixing, dispersing, heat transfer and mass transfer of the high viscosity liquid are gradually achieved.
[0036] Specifically, the device is placed in the stirring tank, the driving device drives the shaft 1 to rotate, the outer wing plate 2 rotates synchronously, and the plurality of tooth plates 3 on the outer wing plate 2 rotate in the high viscosity fluid. Under the action of centrifugal force, the high viscosity fluid flows outward at high speed along the outer wing plate 2, forms a laminar flow area, is dispersed by the shearing of the sharp protruding part of the tooth plate 3, and the turbulent degree of the high viscosity fluid is further increased, the discharge flow of the high viscosity fluid is increased, and the liquid with high discharge flow rate is reduced. The dead zone in the stirring tank is reduced. The problem that a large number of dead zones appear in the stirring of the high viscosity fluid, and the stirring effect of various stirring requirements such as mixing, dispersing, heat transfer and mass transfer is very poor is solved.
[0037] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in some embodiments, the plurality of tooth plates 3 are arranged side by side on the outer wing plate 2 along the length direction of the shaft 1, and the plurality of tooth plates 3 increase one by one downward. The number of tooth plates 3 is preferably four, and the width of the four tooth plates 3 increases one by one downward, so that each tooth plate 3 provides different shearing force to better disperse the laminar flow area, increase the discharge flow of the high viscosity fluid, and further improve the stirring effect of the high viscosity liquid.
[0038] In some embodiments, the outer wing plate 2 and the tooth plate 3 are integrally formed. The production cost of the outer wing plate 2 and the tooth plate 3 is greatly reduced, the production speed of the outer wing plate 2 and the tooth plate 3 is improved, and the firmness and stability between the outer wing plate 2 and the tooth plate 3 are also guaranteed.

The hub 4 is sleeved and fixed on the shaft 1, and the hub 4 rotates synchronously with the rotation of the shaft 1, so that the stability of the rotation of the shaft 1 is improved.

[0040] In some embodiments, the single-wing-plate radial flow impeller further comprises a root wing plate 5 arranged on the hub 4, and the root wing plate 5 is fixedly connected with the outer wing plate 2. Further, the inner wing plate 6 is arranged on the root wing plate 5, and one side of the inner wing plate 6 is connected with the hub 4. Wherein, two root wing plates 5 are arranged on each hub 4, and the two root wing plates 5 are distributed on the two sides of the hub 4 at 180°, and the root wing plate 5 is used to connect the outer wing plate 2 and the hub 4. The connection mode of the root wing plate 5 and the outer wing plate 2 is detachable connection, and the detachable connection mode is convenient for maintenance, replacement and maintenance of the outer wing plate 2, and the connection mode is preferably screwed.
[0041] In some embodiments, the width of the inner wing plate 6 decreases away from the hub 4 along the length direction of the root wing plate 5. The arrangement of the inner wing plate 6 strengthens the connection relationship between the hub 4 and the inner wing plate 6, and makes the connection between the hub 4 and the inner wing plate 6 more stable when the shaft 1 rotates. The inner wing plate 6 plays a certain auxiliary role in the destruction of the laminar flow region under the condition of rotation of the shaft 1, better cuts and disperses the liquid in the laminar flow region to the outer wing plate 2, so that the tooth plate 3 on the outer wing plate 2 further disperses the liquid in the laminar flow region.
[0042] Referring to Figure 6 and Figure 7 In some embodiments, the single-wing-plate radial flow impeller further comprises an end rod 7 arranged on the side wall of the outer wing plate 2. Wherein, the end rod 7 is arranged on the side of the outer wing plate 2 through the connecting rod 8, and the position is on the opposite side of the side where the outer wing plate 2 is connected with the root wing plate 5.

It is extremely beneficial to the stirring of liquid mixing, mass transfer and heat transfer between high-density-difference liquid and high-viscosity-difference liquid.
[0043] It should be noted that a certain radian can also be arranged in the rotation direction of the end rod 7 to further improve the stirring effect.
[0044] Referring to Figure 8 In some embodiments, the single-wing-plate radial flow impeller further comprises an end wing plate 9, the end wing plate 9 comprises a first end plate 901 and a second end plate 902, and the first end plate 901 and the second end plate 902 are arranged on the side wall of the outer wing plate 2. The first end plate 901 is away from the outer wing plate 2, and the end corner close to the shaft 1 is twisted downward, and the second end plate 902 is away from the outer wing plate 2, and the end corner close to the shaft 1 is twisted upward. Preferably, the twist angle of the edge corner of the first end plate 901 and the twist angle of the edge corner of the second end plate 902 are the same, both are α, 30≥α>0.
[0045] Wherein, the first end plate 901 and the second end plate 902 can also be connected with the outer wing plate 3 through the connecting rod 8. The first end plate 901 on each outer wing plate 2 is preferably two, the second end plate 902 on each outer wing plate 2 is preferably one, the first end plate 901 is arranged above the second end plate 902, the first end plate 901 has a downward arc in the rotation direction, the second end plate 902 has an upward arc in the rotation direction, during the stirring process, a larger pressure is generated on the front of the outer wing plate 2, a certain negative pressure is generated at the back of the outer wing plate 2 and the position of the end wing plate 9, and a strong pressure difference is formed, and then the high-strength shearing of the tooth plate 3 breaks the laminar flow region and reduces the appearance of the dead zone in the stirring tank.
[0046] Referring to Figure 8 the placement position, when the shaft 1 rotates clockwise, due to the end angle of the first end plate 901 and the arc of the second end plate 902, the first end plate 901 position in the stirring tank will generate an upward liquid flow, and the second end plate 902 position will generate a downward liquid flow, so that the degree of turbulent flow of the high-viscosity fluid is further increased, the discharge flow of the high-viscosity fluid is improved, and the dead zone in the stirring tank is reduced. In the stirring of high-viscosity fluid, the appearance of the dead zone is reduced, and the mixing, dispersion, heat transfer and mass transfer and other various stirring are better
