Description

Technical Field

[0001] The utility model relates to the technical field of homogenizers, and specifically relates to an efficient homogenizer for coating processing. Background Technique

[0002] A coating homogenizer is a device specifically used in the coating production process. Its main function is to homogenize coating raw materials (such as pigments, resins, solvents, etc.) to ensure that the components of the coating are evenly distributed, achieving ideal physical and chemical properties. This device is crucial in the coating industry because a uniform coating can not only improve the coating quality but also enhance the performance and service life of the coating.

[0003] In coating processing, the homogenizer significantly improves the uniformity of the coating, reduces the particle size, and improves the rheology through high shear force and uniform mixing, thereby enhancing the coating performance and production efficiency. For a homogenizer used in coating processing, it is necessary to clean the inside in time after use. However, for a multi-stage homogenizer, its disassembly and assembly are relatively difficult, and the internal parts are complex and diverse, making the cleaning process extremely cumbersome; although the cleaning process of a simple-structured single-stage homogenizer is relatively easy, its homogenization efficiency and quality are lacking; therefore, in view of the above current situation, there is an urgent need to develop an efficient homogenizer for coating processing to overcome the deficiencies in current practical applications and meet the current requirements. Content of the Utility Model

A partition is integrally formed inside the housing, and the partition divides the inside of the housing into two chambers. A rotor a and a rotor b are respectively rotatably installed in the two chambers. The drive shaft sequentially penetrates stator b, rotor b, the partition, and rotor a, and both rotor a and rotor b are drivingly connected to the drive shaft. The drive shaft is rotatably connected to stator b and the partition;

[0011] Preferably, a plurality of through grooves are provided at the edge position of the partition plate and are evenly distributed in a ring shape.

[0012] Preferably, a discharge pipe penetrates through the edge position of the stator b, and one end of the discharge pipe is horizontally aligned with the eddy current fan blade. Specifically, through the provided eddy current fan blade, the processed coating is discharged through the discharge pipe.

[0037] Preferably, a feed inlet 101 for feeding is provided at the middle position of the stator a10. Specifically, through the provided feed inlet 101, an external feeding device is connected to introduce the coating to be processed between the stator a10 and the rotor a30, so that the coating to be processed is located at the discharge fan blade 301.

[0038] Preferably, a plurality of through grooves 202 are provided at the edge position of the partition plate 201 and are equidistantly distributed in a ring shape. Specifically, the two chambers of the housing 20 are communicated through the provided through grooves 202. After the paint is homogenized in one chamber, it enters the other chamber for secondary treatment, achieving a multi-stage homogenization effect.

[0039] Preferably, a discharge pipe 502 is penetrated through the edge position of the stator b50, and one end of the discharge pipe 502 is horizontally aligned with the eddy current fan blade 401. Specifically, the processed paint is discharged through the discharge pipe 502 by the provided eddy current fan blade 401.

[0040] Preferably, there are three groups of arc-shaped blocks a102, and each group of arc-shaped blocks a102 is distributed in a ring shape. There is a gap between adjacent arc-shaped blocks a102.

[0042] Working principle: Connect the end of the drive shaft 60 to an external power device. The external power device drives the drive shaft 60 to rotate at a high speed, and then the drive shaft 60 drives the rotor a30 and the rotor b40 to rotate at a high speed. The paint to be processed enters the interior of the cavity through the feed port 101 and is guided to the edge position by the discharge fan blades 301 on the outside of the rotor a30. During this process, the paint to be processed will sequentially pass through the shear channels formed between adjacent arc-shaped blocks a102, and the high-speed rotating shear cutter head a302 cooperates with the shear channels to shear and homogenize it. Subsequently, the preliminarily processed paint will enter the chamber on the opposite side through the through groove 202 and move from the edge towards the middle position under the drive of the high-speed rotating eddy fan blades 401 and the guide cutter head 403. During this process, the preliminarily processed paint will sequentially pass through the shear channels between the arc-shaped blocks b501, and the high-speed rotating shear cutter head b402 cooperates with the shear channels to shear and homogenize it. Finally, the processed paint is discharged through the discharge pipe 502.
