Description

viscous material mixer

technical field

The utility model relates to a stirrer, in particular to a stirrer which can be applied to material systems with different viscosities at the same time.

Background technique

Agitators are widely used in chemical, food, light industry, pharmaceutical and other fields. Under the action of the agitator, it is beneficial to the uniform dispersion and mixing of materials in liquid-liquid, gas-liquid and other systems, and at the same time, the mass and heat transfer of the reaction system is enhanced, which is conducive to the progress of the reaction, and at the same time avoids local overheating in the system. In industry, agitators are often selected according to different reactions and material characteristics. Common agitator types include: propeller agitator, turbine agitator, paddle agitator, anchor agitator, ribbon agitator, etc. .

For the mixing of high-viscosity materials, whether the shape of the agitator is reasonable is very important. Ordinary agitators generally use paddles at the end of the agitator shaft. This kind of agitator is good for mixing thin materials, but for high-viscosity materials, due to the poor fluidity of viscous materials, the paddles of the agitator The rotation of the blade can only stir the material at the bottom, and the material does not mix well up and down, which affects the mixing effect of the whole material.

Chinese patent CN2430211Y announces a kind of wall-scraping agitator, which is suitable for the mixing of two-phase materials with a large difference in density, but it is not suitable for the mixing of high-viscosity materials because there is a tie bar between the stirring frame and the scraper.

Contents of the invention

In order to solve the above technical deficiencies, the utility model provides a viscous material agitator which is suitable for both low-viscosity materials and high-viscosity materials, and has better stirring effect on high-viscosity materials.

The utility model is achieved through the following measures:

A viscous material stirrer, comprising a stirring shaft, the end of the stirring shaft is provided with straight blades, the outer surface of the stirring shaft is provided with propeller blades, the propeller blades are in a spiral shape, and the propeller blades spirally surround the stirring shaft The outer surface of the shaft, the propeller blades extend from the top of the stirring shaft to the end of the stirring shaft.

Preferably, there are two propeller blades, which are arranged parallel to each other and spirally arranged on the outer surface of the stirring shaft.

There are 3 straight blades, and the horizontal angle between two adjacent straight blades is 120 degrees.

The beneficial effects of the utility model are:

1. The utility model is suitable for stirring material systems with different viscosities, especially for high-viscosity material systems.

2. The utility model stirs evenly. When the stirring shaft of the stirrer rotates, the propeller blades on the stirring shaft follow the rotation, thereby turning the surrounding materials and forcing the viscous materials to flow up and down, so that the materials are fully mixed while left and right. Mix up and down, the overall material mixing effect is good.

3. The utility model is simple in structure, low in cost, and has the advantages of maintenance and daily maintenance by using the agitator.

Description of drawings

Fig. 2 is a schematic diagram of the structure of the front view of Embodiment 2.

In the figure: 1 stirring shaft, 2 propeller blades, 3 straight blades.

Detailed ways

Example 1

As shown in Figure 1, a viscous material agitator of the present utility model includes a stirring shaft 1, and the end of the stirring shaft 1 is provided with a straight paddle 3, and there are 3 straight paddles 3, and the horizontal clamp between two adjacent straight paddles The angle is 120 degrees. The outer surface of the stirring shaft 1 is provided with a propeller blade 2, the propeller blade 2 is in a spiral shape, and the propeller blade 2 spirally surrounds the outer surface of the stirring shaft 1, and the propeller blade 2 extends from the top of the stirring shaft to the end of the stirring shaft.

The working principle of the utility model is: when the stirring shaft 1 rotates, the straight blade at the end of the stirring shaft 1 rotates, and at the same time the propeller blade 2 also rotates, thereby turning the material around the propeller blade 2, forcing the viscous material to flow up and down, and the material is in the While mixing left and right, it also fully mixes up and down, so that the mixing is more fully and evenly.

Example 2

A kind of viscous material stirrer, structure is the same as embodiment 1, difference is:

There are two propeller blades 2, which are spirally arranged on the outer surface of the stirring shaft 1 in parallel with each other, as shown in Fig. 2 .
