Embodiment 1

[0032] This embodiment provides a powder homogeneous treatment device, such as figure 1 shown, which includes:

[0033] Silo, ultrasonic treatment device (20KHZ\3000W produced by Ningbo Xianchang Company), powder classification device, membrane separation device and solid-liquid separation device.

[0034] The silo is used to contain the powder to be homogenized and the liquid solvent used to dilute the powder; the ultrasonic treatment device is used to perform ultrasonic treatment on the powder to be treated, that is, to reduce the particle size to improve the homogenization of the powder; the powder classification device is used to perform multi-stage screening on the powder to be processed, filter out the powder whose particle size does not meet the standard, and screen out the powder that meets the standard body; the membrane separation device and the solid-liquid separation device are both used to separate the qualified powder from the liquid solvent, thereby preparing a...

Embodiment 2

[0044] This embodiment provides a method for homogenizing powder, which is characterized in that it comprises the following steps:

[0045] Simultaneously transport the powder to be homogenized and the liquid solvent used to disperse the powder to the ultrasonic treatment device and the powder classification device from the silo;

[0046] The ultrasonic treatment device performs ultrasonic treatment on the powder, and at the same time, the powder classification device performs particle size screening on the powder;

[0047] Return the powder ultrasonically treated by the ultrasonic treatment device together with the liquid solvent to the silo, and transport the powder with a particle size up to the standard sieved by the powder classification device together with the liquid solvent to the membrane A separation device, returning the powder with a substandard particle size sieved by the powder classification device to the silo together with the liquid solvent;

[0048] The memb...

Abstract

The invention provides a powder homogeneous treatment method, comprising the following steps: simultaneously transporting a mixture of powder and liquid solvent to be homogenized to an ultrasonic treatment device and a powder classification device from a silo; the ultrasonic treatment device and the powder classification The device operates at the same time; the ultrasonically treated mixture is returned to the silo, and the powder with a particle size that meets the standard treated by the powder classification device is transported to the membrane separation device together with the liquid solvent, and the particle size processed by the powder classification device is sent to the membrane separation device. The unqualified powder is sent back to the silo together with the liquid solvent; the slurry treated by the membrane separation device is sent to the solid-liquid separation device, and the liquid solvent separated by the membrane is sent back to the ultrasonic treatment device; The powder processed by the solid-liquid separation device is delivered to the finished product warehouse. The invention uses a liquid solvent to disperse the powder, ultrasonic treatment and sieving are performed simultaneously, and the powder can be separated in time when the physical size of the powder meets the requirements, which solves the problem of particle size uniformity of the powder.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a powder homogeneous treatment method and equipment for realizing the method. Background technique [0002] In the early 1980s, micropowder technology gradually developed and became the focus of research in countries all over the world. [0003] The micropowder refers to a microscopic solid particle whose physical size is between that of a molecule, an atom, and a bulk material, and generally refers to a small solid particle within the range of D97≤10 μm. Micropowder can include: particles of various materials such as metal, nonmetal, organic, inorganic and biological. With the ultrafineization of the substance, the surface electronic structure and crystal structure have changed, resulting in a surface that is not available in bulk materials. Effect, small size effect, quantum effect and macroscopic quantum tunneling effect, so that ultrafine powder has a series of int...
