[0035] Please refer to Figures 1-4 The utility model provides technical scheme: The utility model discloses a complex wing plate radial flow type impeller, which comprises:
[0036] The outer wall of the shaft rod 1 is fixedly sleeved with a hub 2;
[0037] The outer wall of the hub 2 is uniformly welded with hub root leaves 3 at an angle of 180 degrees;
[0038] The outer side end of the hub root leaf 3 is fixedly assembled with a main wing 4, and a toothed groove 6 is formed in the outer side edge of the main wing 4; when the main wing 4 rotates, liquid flows outward at a high speed along the surface under the action of centrifugal force, and the degree of turbulent flow of the liquid is further enhanced through shearing of the toothed groove 6;
[0039] The main wing 4 is fixedly assembled with an auxiliary wing 5 in a clockwise direction, and the main wing 4 and the auxiliary wing 5 are kept at a certain distance; when the stirrer rotates, a relatively large pressure is generated on the front face of the main wing 4, and a certain negative pressure is generated on the back face of the auxiliary wing 5, thereby forming a relatively strong pressure difference between the front and back; the pressure difference cooperates with the rotation of the main wing 4 and the auxiliary wing 5 to generate strong ejection flow and ejection flow rate outward along the radial direction of the shaft, and then the high-strength shearing of the toothed groove 6 of the main wing 4 can be suitable for liquid-liquid mixing with high viscosity, high specific gravity and high viscosity difference, and the stirring effect is good, and the stirring conditions can adapt to a wide viscosity range.
[0040] In some embodiments, in order to generate a strong upward flow, the hub root leaf 3 is integrally formed with a baffle 7 in a counterclockwise direction, and the upward flow drives the medium to flow up and down, thereby improving the effect of liquid-liquid mixing with high viscosity, high specific gravity and high viscosity difference.
[0041] In some embodiments, in order to reduce the stirring resistance, the auxiliary wing 5 is formed in a trapezoidal shape, and the smaller end of the auxiliary wing 5 faces upward.
[0042] In some embodiments, in order to reduce the stirring resistance, to form the stirring around the blade and the center of the annular arrangement of the stirring piece, to mix the material more fully, to improve the mixing efficiency of the material, the upper end size of the main wing 4 is smaller than the lower end size.
[0043] In some embodiments, in order to ensure the strength of the fixed connection between the auxiliary wing 5 and the main wing 4, the support column 8 is fixedly connected between the auxiliary wing 5 and the main wing 4, and the number of support columns 8 is three.
[0044] The three support columns 8 are longitudinally distributed along the position between the auxiliary wing 5 and the main wing 4.
[0045] In some embodiments, in order to enhance the effect of the pressure difference between the auxiliary wing 5 and the main wing 4 by this misalignment, the auxiliary wing 5 and the main wing 4 are misaligned in front and back, and the outer side end of the auxiliary wing 5 in the front and back direction of the main wing 4 is located outside the main wing 4. After the misalignment design, the range of action of the pressure difference is expanded, and the effect of the pressure difference is enhanced.
[0046] In some embodiments, in order to ensure the strength of the connection between the hub root blade 3 and the main wing 4, the mounting hole is uniformly provided on the hub root blade 3, and the number of mounting holes is four.
[0047] The four mounting holes are distributed in a rectangular shape.
[0048] The bolt and the nut are fixedly connected between the mounting hole and the inner side end of the main wing 4.
[0049] In some embodiments, in order to improve the strength of the connection of the main wing 4, the number of hubs 2 is two, which are distributed above and below, and the two side hubs 2 are fixedly sleeved on the shaft rod 1.
[0050] The inner side end of the main wing 4 is fixedly connected with the upper and lower hubs 2 through the hub root blade 3. The additional hub 2 provides two connection fixed positions above and below, and improves the strength of the connection of the main wing 4.
[0051] In some embodiments, in order to make the stress evenly distributed and avoid stress concentration, improve the service life, and at the same time the circular arc surface 9 can reduce the stirring resistance, the bottom surface of the main wing 4 is a circular arc surface 9.
[0052] In some embodiments, in order to improve the liquidity of the liquid and improve the mixing uniformity, the inner side end of the circular arc surface 9 is inclined downward to form a sharp end. This sharp end changes the flow direction of the liquid below the main wing 4, improves the liquidity of the liquid, and improves the mixing uniformity.
[0053] Working principle:
[0054] The hub root blade 3 is fixedly assembled with the main wing 4 at the outer side end, and the outer side edge of the main wing 4 is provided with a toothed groove 6; when the main wing 4 rotates, liquid flows outward along the plate surface at high speed under the action of centrifugal force, and the shearing of the toothed groove 6 further enhances the turbulent degree of the liquid;
[0055] The main wing 4 is fixedly assembled with the auxiliary wing 5 in the clockwise direction, and the main wing 4 and the auxiliary wing 5 keep a certain distance; when the stirrer rotates, a greater pressure is generated on the front face of the main wing 4, and a certain negative pressure is generated on the back face of the auxiliary wing 5, so that a strong pressure difference is formed in front and back, which, in combination with the rotation of the main wing 4 and the auxiliary wing 5, generates a strong ejection flow and ejection flow rate outward from the shaft outer diameter, and then the high-strength shearing of the toothed groove 6 of the main wing 4 can be suitable for liquid-liquid mixing with high viscosity, high specific gravity and high viscosity difference, and the stirring effect is good, and the stirring condition is suitable for a wide viscosity range.
[0056] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
