Description

Technical Field

[0001] The utility model belongs to the technical field of mixture separation, and in particular relates to a device system for separating mixed media in mixed powder. Background Art

[0002] Powder metallurgy is a process for producing metal powders or using metal powders (or mixtures of metal and non-metallic powders) as raw materials, forming and sintering them to create metal materials, composite materials, and various other products. Powder metallurgy shares similarities with ceramic production, both involving powder sintering techniques. Therefore, a range of new powder metallurgy technologies can also be applied to the preparation of ceramic materials. Due to its advantages, powder metallurgy has become the key to solving new material problems and plays a vital role in the development of new materials.

[0003] Powder mixing refers to the process of moving solid particles of different components in a large range and mixing them during the back-and-forth flow, so that two or more materials are evenly mixed together to form alloy powder. It is an important step before powder molding.

[0004] During the powder mixing process, a mixing medium is often used to ensure that the powders are thoroughly mixed and uniform. This helps the different powders blend together. The medium is usually made of a large particle size similar to the mixed material. However, after the powders are mixed, the mixing medium is dispersed within the mixed powders and cannot be easily separated.

[0005] Currently, the method for separating the mixed medium includes removing the powder from the mixer and then sieving it through a sieve to separate the mixed medium from the powder. However, this separation method has the following disadvantages: (1) the separation process of the mixed powder is prone to secondary contamination of the powder, and impurities are easily mixed into the powder during the sieving process, reducing the purity of the powder; (2) repeated separation and sieving will cause the powder to be exposed to the air for too long, thereby oxidizing.

[0006] Therefore, it is necessary to provide a device system that can ensure the smooth separation of powder and medium without affecting the powder purity, gas content, etc. Utility Model Content

[0007] In response to the shortcomings of the prior art, the present invention aims to provide a device system for separating a mixed medium from a mixed powder. This device system reduces human involvement and reduces the time the powder is exposed to air, thereby ensuring that the powder purity and gas content are minimized during the separation process.
