Description

Technical Field

[0001] This utility model relates to a stirrer, specifically an energy-saving, high-efficiency, self-stabilizing stirrer. Background Technology

[0002] When the agitator is running, it will oscillate due to the resistance of the fluid, especially the end of the agitator. Currently, in order to solve this problem, most methods use a support frame at the bottom of the agitator to support the agitator shaft. However, this method will also hinder the operation of the agitator shaft and will not increase the amount of liquid discharged by the agitator. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention provides an energy-efficient and self-stabilizing agitator. This invention increases the blade area, reduces the resistance at the blade surface, and increases the discharge capacity of the agitating blades, achieving high efficiency and energy saving. The addition of a stabilizing cylinder increases the damping effect on the agitated material, reduces the runout at the shaft end, and achieves a self-stabilizing effect. This improves the service life of the equipment's drive system, namely the motor reducer bearings, reduces the energy consumption of the agitating equipment, increases the discharge capacity of the agitator, and improves the agitation effect.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: an energy-saving and high-efficiency self-stabilizing stirrer, comprising a hub, blades and a stabilizing cylinder, wherein there are at least three blades evenly distributed on the hub, and the bottom surface of the blades is fixedly connected to the stabilizing cylinder.

[0005] Furthermore, the stabilizing cylinder is welded to the bottom surface of at least three of the blades.

[0006] Furthermore, the stabilizing cylinder is a hollow cylinder with openings at both the top and bottom.

[0007] Furthermore, the angle α2 between the blade and the central hub is 66°.

[0008] Furthermore, the angle α1 between the blade and the plane perpendicular to the central hub axis is 16°.

[0009] Furthermore, the ratio of the maximum width to the minimum width of the blade is 1.8 to 2.8 times.

[0010] In summary, this utility model achieves the following technical effects:

[0011] This invention increases the blade area, reduces the resistance on the blade surface, and increases the discharge capacity of the stirring blade, thereby achieving high efficiency and energy saving.

[0012] The addition of a stabilizing cylinder increases the damping effect on the materials being stirred, reduces the runout at the shaft end, extends the service life of the equipment drive system (i.e., the motor reducer bearings), reduces the energy consumption of the stirring equipment, increases the discharge volume of the stirring equipment, and improves the stirring effect.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] Example:

[0023] Figure 1 It is an energy-saving, high-efficiency, self-stabilizing agitator. Figure 2 yes Figure 1 Top view, Figure 3 This is a schematic diagram of the impeller, including a hub 1, impeller blades 2, and a stabilizing cylinder 3. At least three impeller blades 2 are evenly distributed on the hub 1, and the bottom surface of each impeller blade 2 is fixedly connected to the stabilizing cylinder 3. The hub 1 is fixed to the stirring shaft, the impeller blades 2 are used to stir the liquid, and the stabilizing cylinder 3 is used to increase stability and achieve a self-stabilizing effect.

[0024] The stabilizing cylinder 3 is welded to the bottom surface of at least three of the blades 2. The stabilizing cylinder 3 is a hollow cylinder with openings at both the top and bottom.

[0025] This invention incorporates a stabilizing cylinder. In general fluids, a stabilizing cylinder is welded below the agitator. The damping effect of the liquid within the tank on the stabilizing cylinder reduces agitator oscillation, keeping the runout of the agitator shaft within acceptable limits. This effect is particularly noticeable under conditions with linear velocities greater than or equal to 4 m / s. As the agitator rotates at high speed, the liquid flowing towards the stabilizing cylinder through the agitator blades interacts with it, generating a damping force. This damping force is related to the area and flow rate of the liquid facing the cylinder; a larger surface area results in more stable damping. When the agitator shaft rotates in the medium, the presence of the stabilizing cylinder increases the damping effect on the agitated material, reduces the runout at the shaft end, extends the service life of the drive system (motor, reducer, and bearings), reduces energy consumption, increases the discharge capacity, and improves the agitation effect.

[0026] The angle α2 between the blade 2 and the central hub is 66°. The angle α1 between the blade 2 and the plane perpendicular to the axis of the central hub is 16°. The ratio of the maximum width to the minimum width of the blade 2 is 1.8 to 2.8 times.

[0027] This invention increases the blade area, reduces the resistance on the blade surface, and increases the discharge capacity of the stirring blade, thereby achieving high efficiency and energy saving.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
