Description

Technical Field

[0001] The utility model belongs to the technical field of dispersers, in particular to a multi-stage high-efficiency disperser. Background Art

[0002] A disperser is a type of mixer in a broad sense. Because it uses a high-speed agitator (such as a disc sawtooth agitator) to form strong turbulence locally, it usually has a strong dispersing and emulsifying effect on the material, so this type of high-speed mixer is also called a disperser.

[0003] Existing dispersers usually use a driving mechanism to drive the dispersion rod, which makes the material stirred evenly and regularly in the same direction. However, this dispersion method has some limitations in the actual working process, mainly manifested in that the dispersion effect is average and it cannot efficiently handle high-viscosity or difficult-to-disperse materials, thereby reducing the working efficiency of the disperser. For this reason, a multi-stage high-efficiency disperser is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1-Figure 4 As shown, a multi-stage high-efficiency disperser provided by an embodiment of the utility model includes a tank body, on which a feed port 71 and a discharge port 72 are provided for inputting and outputting slurry, and further includes:

[0027] The fixed connection seat 03 is fixedly arranged on the tank body and is used for installing the servo motor 04 .

[0028] The servo motor 04 is fixedly mounted on the fixed connection seat 03 and is used to drive the central shaft 06 to rotate. The use of the servo motor 04 can achieve fine control of the dispersion process, including accurate setting of the rotation speed and the rotation direction, so as to adapt to different dispersion requirements and material properties.

[0029] The central axis 06 has one end fixedly connected to the output end of the servo motor 04, and the other end of the central axis 06 extends into the tank body and is rotatably connected to the bottom wall of the tank body; the rotation of the central axis 06 can drive the dynamic rotor blades 08 and the static rotor blades 09 to work.

[0030] The seal 05 is sleeved on the outer ring of the central axis 06 and fixed between the central axis 06 and the tank body; it effectively prevents slurry leakage, ensures the cleanliness of the operating environment, and also reduces the risk of cross contamination.

[0031] The dynamic rotor blades 08 are fixedly arranged on the central shaft 06; they rotate at high speed along with the rotation of the central shaft 06, and collide and cut with the static rotor blades 09, so as to achieve the effect of mixing and dispersing the slurry.

[0032] Static vanes 09 are fixedly arranged on the inner wall of the tank body. They are used together with dynamic vanes 08, but do not rotate with the central axis 06. When the dynamic vanes 08 rotate with the central axis 06, the static vanes 09 remain stationary. This design enables relative movement between the dynamic vanes and the static vanes 09, thereby generating collision and cutting effects, thereby achieving efficient mixing and dispersion of the slurry.

[0033] In the embodiment of the utility model, the slurry enters the mixing tank 11 from the feed port 71, and the servo motor 04 drives the dynamic rotor blade 08 to rotate. When the dynamic rotor blade 08 rotates with the central axis 06, the static rotor blade 09 remains stationary. The relative movement between the two produces a collision and cutting effect, thereby achieving mixing and dispersion of the slurry. The mixed and dispersed slurry is output from the discharge port 72.

[0034] like Figure 1 and Figure 2As shown, as a preferred embodiment of the utility model, the tank body includes a mixing tank 11 and a tank cover 12, a feed port 71 and a discharge port 72 are provided on one side of the mixing tank 11, a fixed connection seat 03 is fixedly connected to the tank cover 12, and a seal 05 is provided between the tank cover 12 and the central axis 06.

[0035] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, a circulating pipe water return port 21 and a circulating pipe water inlet 22 are provided on the other side of the mixing tank 11, which are used as interfaces for cooling and preheating circulating pipes, and can be connected to an external cooling or preheating system to control the temperature in the mixing tank 11, and are suitable for temperature-sensitive materials.

[0036] like Figure 2 As shown, as a preferred embodiment of the utility model, a through hole is provided in the fixed connection seat 03, and the inner diameter of the through hole is adapted to the outer diameter of the central axis 06, so as to ensure that the central axis 06 can pass through stably and maintain good centering performance.

[0037] like Figure 3 and Figure 4 As shown in FIG. 1 , as a preferred embodiment of the present invention, a through slot 91 is provided at the center of the static rotor blade 09, the central axis 06 passes through the through slot 91, and there is a certain distance between the central axis 06 and the inner wall of the through slot 91. Thus, when the dynamic rotor blade 08 rotates with the central axis 06, the static rotor blade 09 remains stationary.

[0038] like Figure 1 As shown, as a preferred embodiment of the utility model, the static rotor blades 09 are provided with two groups. The rotor blades are arranged from top to bottom as dynamic rotor blades 08 - static rotor blades 09 - dynamic rotor blades 08 - static rotor blades 09 - dynamic rotor blades 08. This alternating hierarchical arrangement helps to achieve a more uniform and efficient dispersion effect.

[0039] like Figure 1 As shown, as a preferred embodiment of the utility model, the dynamic rotor blades 08 are provided with three groups. The combination of three groups of dynamic rotor blades 08 and two groups of static rotor blades 09 improves the dispersion efficiency and quality, and is particularly suitable for materials with high viscosity or difficult to disperse.

[0040] like Figure 1 As shown, as a preferred embodiment of the utility model, the mixing tank 11 and the fixed connection seat 03 are both made of stainless steel, which helps to improve the durability and hygiene of the equipment.

[0041] The working principle of the utility model is:

[0042] In this multi-stage high-efficiency disperser, the slurry enters the mixing tank 11 from the feed port 71, and the servo motor 04 drives the dynamic rotor 08 to rotate. When the dynamic rotor 08 rotates with the central axis 06, the static rotor 09 remains stationary. The relative movement between the two produces a collision and cutting effect, thereby achieving mixing and dispersion of the slurry, and the mixed and dispersed slurry is output from the discharge port 72.

[0043] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
