Application and Development Prospects of New Nano-Micron Powder Filter Machines
Release time:
2025-08-22
Introduction
With the rapid development of new materials, new energy, biomedicine, and high-performance manufacturing industries, the application scope of powder materials continues to expand, placing higher demands on their purity, particle size distribution, and cleanliness. Traditional filtration equipment often faces issues such as low filtration efficiency, insufficient filtration precision, incomplete cleaning, and secondary pollution when handling high-precision, complex slurry systems. To address these pain points, a new type of nano-micron powder filter machine has emerged. It leverages independently developed filtration medium preparation technology, a closed operation process, and a unique material flow channel opening technology to 25nm achieve solid-liquid separation at the level, demonstrating strong application potential across various industries.
1. Working Principle
1. Filtration Medium
The core of the equipment lies in the filtration medium. It uses a self-developed and patented filtration medium (patent number: ZL 202211217869.2 ), with a maximum retention precision reaching 25nm . This means the equipment can effectively retain tiny particles and even nano-level impurities, ensuring the purity and particle size distribution of the final product. Compared to traditional filtration materials, the new medium not only offers high filtration precision but also excellent chemical corrosion resistance and pressure resistance, enabling long-term stable operation under complex conditions.
2. Filtration Process
The slurry is first delivered into the filtration chamber by a diaphragm pump. Driven by compressed air, the liquid part passes through the filter membrane and is discharged, while solid particles are evenly retained on the membrane surface forming a filter cake. The entire process is completed in a fully enclosed environment , without contact with the outside world. This closed operation effectively prevents secondary contamination of the material, protects the operating environment, and meets the requirements of green production. As the filter cake gradually forms, the equipment can still maintain stable filtration efficiency, thanks to its unique flow channel control design.
3. Cleaning Process
To ensure the cleanliness of the filter cake and the interior of the equipment, the device is equipped with an independent cleaning pipeline. The cleaning liquid (appropriate solvents or deionized water can be selected according to different processes) is pumped into the filtration chamber by a diaphragm pump, passes through the filter membrane under the drive of compressed air, and is discharged, carrying away residual impurities. Subsequently, the equipment uses compressed air for drying treatment, making the material cleaner and drier. The entire cleaning process is also carried out under closed conditions, which not only avoids cross-contamination but also enables recycling of the cleaning liquid, significantly reducing operating costs.
4. Material Flow Channel Opening Technology
Traditional filtration equipment often experiences filtration interruptions or cleaning dead zones due to filter cake accumulation or incomplete cleaning. The new filter machine modifies the surface of the filtration medium and combines multiple integrated technologies to develop " Material Flow Channel Periodic Opening ” Function:
- During the filtration stage, periodic opening of the flow channel prevents excessive clogging of the filter cake, ensuring continuous and stable filtration.
- During the cleaning stage, periodic opening of the flow channel eliminates cleaning dead zones, allowing the cleaning liquid to cover the entire membrane surface, achieving thorough cleaning.
This design not only improves the stability and continuity of the equipment but also significantly enhances the efficiency and effectiveness of filtration and cleaning.
2. Application Fields
1. Battery Materials
In the production of lithium-ion battery cathode and anode materials (such as lithium cobalt oxide, lithium iron phosphate, silicon-carbon materials, etc.), powder purity and particle size distribution directly affect battery energy density and cycle life. The new filter machine can precisely control particle size, remove impurity particles, and ensure consistency and electrochemical performance of electrode materials.
2. Non-metallic Minerals
Non-metallic mineral powders such as kaolin, quartz, talc, and calcite are widely used in coatings, papermaking, plastics, and other industries. Through high-precision filtration, ultrafine powders with uniform particle size distribution and low impurity content can be obtained, thereby improving product whiteness, strength, and processing performance.
3. Fine Chemicals
Fine chemical materials such as white carbon black, titanium dioxide, precipitated barium sulfate, and polymer powders have stringent requirements for purity and particle size. The new equipment can complete high-precision filtration in a closed environment, avoiding external contamination, ensuring product quality, and supporting downstream industries in producing high-end coatings, functional plastics, and specialty chemicals.
4. Ceramic Building Materials
In the production of ultrafine cement, glass powder, ceramic raw materials, etc., particle size distribution uniformity directly affects the strength and durability of products. The application of the filter machine makes the powder finer and more stable, thereby enhancing the comprehensive performance and application value of the materials.
5. Metal Powders
Metal powders such as aluminum powder, nickel powder, and stainless steel powder are widely used in 3D printing and powder metallurgy. This equipment can effectively remove oversized particles and impurities, improve powder flowability and formability, and provide high-quality raw materials for high-end manufacturing.
6. Pharmaceuticals and Food
In the pharmaceutical field, the particle size of drug powders affects the drug release rate. The filter machine can be applied in the preparation of antibiotics, vitamins, and other drugs to ensure controllable particle size and high purity. In food processing, such as starch, lactose, and protein powders, the equipment can also achieve high-standard filtration, complying with food safety regulations.
7. Superhard and High-tech Materials
The preparation of new materials such as silicon carbide, diamond, nano titanium dioxide, and nano calcium carbonate requires extremely high powder purity and uniformity. The new filter machine can ensure the high-performance characteristics of these materials, promoting their application in optoelectronics, electronics, cutting tools, and other fields.
