Description

technical field [0001] The invention relates to a device for gas impact coupling porous top plate stamping, which belongs to the technical field of physical experiment equipment. Background technique [0002] Particle packing and densification has been widely used in energy, chemical, metallurgy, construction and other industries. To achieve fast and efficient particle packing densification, more stringent requirements are put forward for particle packing density and arrangement. At present, there are three main ways to achieve particle accumulation and densification: vibration, compression and gas impact. However, the noise generated by vibration is large, segregation is easy to occur for multi-component particles, and the vibration time to achieve densification is long; during the pressing process, since the force is mainly concentrated near the pressing plate, it is easy to cause uneven distribution of the packing density of the particles, resulting in a higher density a...

Problems solved by technology

However, the noise generated by vibration is large, segregation is easy to occur for multi-component particles, and the vibration time to achieve densification is long; during the pressing process, since the force is mainly concentrated near the pressing plate, it is easy to cause uneven distribution of the packing density of the particles, resulting in a higher density at the top. Large defects; during the gas impact process, due to the difference in the degree of freedom of the particles at different heights of the piled material column, it is easy to form a gradient difference in which the density at the bottom of the material column is greater than that at the top, and the particle layer at the top is affected by the gas impact process. The initial instantaneous gas impact forms an uneven material layer and even some particles splash, resulting in waste and a greater impact on product quality
