Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a high-efficiency powder mixing device. Background Art

[0002] Powder mixing generally refers to the process of evenly mixing two or more powders of different ingredients. Mixing is also the first step in the entire process of preparing a product. The uniform distribution of the mass of each component in the mixture is crucial, because uneven mixing cannot be adjusted in the later process.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese patent number: CN217549539U discloses an efficient powder mixing device. The utility model provides an efficient powder mixing device that can fully and evenly mix a large amount of powder, including a support rod, a rotating shaft, a tank body, a funnel and a solenoid valve, etc. The two sides of the top of the support rod are symmetrically connected to the rotating shaft, the rotating shafts are commonly connected to the tank body, the middle of the tank body is connected to the funnel, and the funnel is connected to the solenoid valve that connects the funnel with the tank body. After the solenoid valve is opened, the powder to be crushed is added to the tank body through the funnel. The stirring blade is driven by a motor to rotate in the tank body, and the stirring blade continuously mixes and stirs the powder in the tank body, so as to achieve efficient, sufficient and even mixing of the powder.

[0005] However, the above patent still has some problems in actual use. The most obvious one is that after repeated use, the scraper will produce a gap with the inner wall of the tank due to wear, thereby affecting the scraping effect and efficiency of the powder on the inner wall of the tank, causing the powder to remain in the tank and difficult to discharge.

[0006] To this end, we proposed an efficient powder mixing device to solve the above-mentioned drawbacks. Utility Model Content
