Inclined paddle type stirrer with shearing wings

Abstract

The utility model relates to the technical field of inclined paddle type stirrers, in particular to an inclined paddle type stirrer with shearing wings, which comprises a hub and an inclined blade, a plurality of shearing wings are arranged on the inclined blade, the edge of the inclined blade is arranged to be zigzag, and the paddle type not only increases the shearing function, but also enhances the stirring and air dissolving effects. The paddle is particularly suitable for the mixing and gas dissolving occasion of high-viscosity liquid, can meet the using conditions under the conditions of low rotating speed and low power consumption, and is more energy-saving compared with a traditional inclined blade.

Description

Technical Field

[0001] The utility model belongs to the technical field of oblique-blade agitators, in particular to an oblique-blade agitator with shearing wings. Background Art

[0002] The oblique-paddle agitator uses obliquely arranged stirring blades, which has a wider stirring range and can form a larger vortex in the stirred liquid, thereby improving the stirring efficiency. It has the characteristics of energy saving, simple structure, stable and reliable operation, and easy maintenance;

[0003] However, its shearing ability is relatively poor, and it is generally suitable for materials with low viscosity. Utility Model Content

[0004] The utility model provides an oblique-paddle stirrer with shearing wings, which can solve the problems pointed out in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising a hub and an inclined-blade paddle, wherein the inclined-blade paddle is provided with a plurality of shear wings, and the edge of the inclined-blade paddle is configured to be serrated.

[0006] Preferably, the plurality of shear wings are arranged in parallel array on the lower end surface of the pitched-blade paddle.

[0007] Beneficial effects: It has the following technical effects:

[0008] 1. Pitched blades, that is, the pitched blades are installed at a certain angle to the horizontal plane, and the fluid has both radial flow and axial flow.

[0009] 2. The edges of the inclined blades are processed with serrations to increase the contact area with the fluid and enhance the shearing effect and gas dissolving function.

[0010] 3. Multiple shear wings are welded under the oblique blades to increase the contact area with the fluid, enhance the shearing effect and gas dissolving function, and at the same time enhance the radial flow to make the mixing effect stronger.

[0011] 4. This type of paddle increases the shearing effect and enhances the stirring and dissolving effect, and is particularly suitable for mixing and dissolving high-viscosity liquids.

[0012] 5. This type of propeller can also meet the use conditions under low speed and low power consumption, and is more energy-efficient than traditional inclined-blade propellers. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model;

[0014] Description of reference numerals:

[0015] Numbers in the figure: hub 1; pitch-blade blade 2; shear wing 3. DETAILED DESCRIPTION

[0016] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0017] Embodiment 1:

[0018] like Figure 1 As shown, a pitched-blade agitator with shearing wings comprises a hub 1 and a pitched-blade paddle 2. The pitched-blade paddle 2 is provided with a plurality of shearing wings 3. The edge of the pitched-blade paddle 2 is arranged in a serrated shape. The plurality of shearing wings 3 are arranged in parallel array on the lower end surface of the pitched-blade paddle 2. The specific connection method may be welding.

[0019] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
