[0002] Powder mixer is a kind of equipment specially used to mix different powder materials together, aiming to achieve uniform processing of materials. Powder mixer plays a vital role in modern industry, especially in chemical, food, building materials, pharmaceutical, fertilizer and other industries, where mixing operation often involves key steps in product quality.

[0003] Powder mixing usually involves three basic methods: convection mixing, shear mixing and diffusion mixing. Convection mixing is achieved by using a stirrer to move the powder in a large range of positions. Shear mixing occurs on the slip surface formed by different speeds between powder particles, similar to the mixing of thin-layer fluids. Diffusion mixing occurs at the microscopic level, achieving uniform mixing through mutual penetration and blending between particles.

[0004] However, during the powder mixing process, differences in the physical properties of the powders, such as particle size, density, shape and fluidity, may lead to segregation or grading during the mixing process, which may easily lead to uneven mixing, long mixing time and the generation of a large amount of dust. In view of this, the present application proposes a powder mixer. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figures 1 to 4 A powder mixer comprises a mixing barrel 1, a guide block 101 is fixedly installed on the inner bottom wall of the mixing barrel 1, and a raw material barrel 2 is penetrated through the top of the mixing barrel 1.

[0024] The raw material barrel 2 includes a barrel body 21 which is inserted into the top of the mixing barrel 1. A bottom plate 22 having the same inner diameter as the mixing barrel 1 is fixedly installed at the bottom of the barrel body 21. A plurality of leakage holes 23 are opened at the top of the barrel body 21. The leakage holes 23 extend to the bottom of the bottom plate 22. A stirring plate 24 is fixedly installed at the bottom of the bottom plate 22. The stirring plate 24 is matched with the guide block 101. Raw materials are loaded into the barrel body 21, and the barrel body 21 is lifted a little. The raw materials leak out into the mixing barrel 1 through the leakage holes 23 and transfer to the barrel body 21, driving the bottom plate 22 to rotate, driving the stirring plate 24 to mix and stir this part of the raw materials, reducing dust and improving mixing efficiency.

[0025] At the same time, two limiting rings 3 are fixedly installed on the surface of the raw material barrel 2, and a support plate 4 is rotatably installed on the surface of the raw material barrel 2, and the support plate 4 is located between the two limiting rings 3. When the support plate 4 is fixed, the raw material barrel 2 can rotate inside the support plate 4.

[0026] Among them, a support column 5 is fixedly installed on the top of the support plate 4, a top plate 6 is fixedly installed on the top of the support column 5, a rotating shaft 7 is rotatably installed on the top of the top plate 6, and the bottom end of the rotating shaft 7 is fixedly connected to the top of the raw material barrel 2.

[0027] Secondly, a rotating motor 8 is fixedly installed on the top of the top plate 6, and the output end of the rotating motor 8 is fixedly connected to the top of the rotating shaft 7. The rotating motor 8 drives the rotating shaft 7 to rotate, drives the raw material barrel 2 to rotate, and drives the stirring plate 24 to mix and stir the raw materials.

[0028] At the same time, a partitioning partition 9 is fixedly installed on the inner wall of the barrel body 21 , a first feed pipe 10 is fixedly installed on the top of the barrel body 21 , and a second feed pipe 11 is fixedly installed on the top of the barrel body 21 .

[0029] The first feed pipe 10 is connected to the left side space of the partition plate 9, and the second feed pipe 11 is connected to the right side space of the partition plate 9. Two groups of different raw materials are respectively fed into the two sides of the partition plate 9 inside the barrel body 21 through the first feed pipe 10 and the second feed pipe 11, and are uniformly leaked into the mixing barrel 1 through the leakage hole 23 when the barrel body 21 rises.

[0030] Embodiment 2: Based on Embodiment 1, a mounting ring plate 12 is fixedly mounted on the surface of the mixing barrel 1, a lifting cylinder 13 is fixedly mounted on the bottom of the mounting ring plate 12, and the movable end of the lifting cylinder 13 is fixedly connected to the bottom of the support plate 4. The lifting cylinder 13 drives the support plate 4 to rise, drives the raw material barrel 2 to rise, and slowly leaks the two groups of raw materials into the interior of the mixing barrel 1 to prevent dust.

[0031] Finally, a discharge pipe 14 is fixedly installed at the bottom of the mixing barrel 1, and the top of the discharge pipe 14 extends into the mixing barrel 1 and is flush with the lowest point of the guide block 101. The guide block 101 guides the mixed powder to the discharge pipe 14, and the powder is discharged through the discharge pipe 14.

[0032] When this embodiment is in use, two groups of different raw materials are respectively fed into the two sides of the partition partition 9 inside the barrel body 21 through the first feeding pipe 10 and the second feeding pipe 11, the rotating motor 8 is turned on to drive the raw material barrel 2 to rotate, and the lifting cylinder 13 is turned on to drive the raw material barrel 2 to rise slowly. The two groups of raw materials slowly fall into the mixing barrel 1 while being stirred by the stirring plate 24, thereby reducing the occurrence of dust, reducing the amount of single mixing, and increasing the mixing efficiency.

[0033] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
