In pharmaceutical production, filtration is a crucial step in ensuring the quality of drugs. Stainless steel duplex filters, with their reasonable structural design and stable working principle, are widely used in the industry. The following analysis will be conducted from two aspects.
1、 Structural Design
1. Core materials and basic structure
materialThe overall material is made of high-quality 304 stainless steel, which has strong corrosion resistance and can resist various chemical substances during the pharmaceutical process, extending the service life of the equipment and meeting the industry's requirements for durability.
main bodyComposed of two cylindrical bodies, using a single-layer stainless steel welded structure, it has stable physical properties and can withstand certain pressure, ensuring the safety of filtration operations.
surface treatmentBoth the inner and outer surfaces are polished to a smoothness of 0.4um, which reduces material residue, facilitates cleaning, lowers the risk of cross contamination, and further enhances corrosion resistance.
2. Key functional components
Filter and support basketThe filter cartridge is equipped with a stainless steel filter screen (different pore sizes can be selected according to needs to accurately filter fine impurities) and a support basket to avoid deformation of the filter screen due to pressure and ensure filtration efficiency.
auxiliary componentThe top vent valve can discharge internal air to prevent air resistance from affecting efficiency; The quick opening cover facilitates quick cleaning and replacement of the filter screen, reducing downtime for maintenance; The bottom three adjustable legs can adapt to different floors and maintain equipment stability.
Connection designThe pipeline is connected by flexible joints or clamps, making installation and disassembly convenient; The inlet and outlet valves are selected as three-way ball valves, which are pressure and temperature resistant, flexible in operation, and can prevent material leakage, meeting hygiene standards.
2、 Working principle
1. Basic filtering process
Liquid materials (such as fresh milk, oral liquids, herbal liquids, etc.) flow into a single working filtration unit from the feed inlet, and after being intercepted by stainless steel filters for impurities, the purified liquid flows out from the discharge outlet to complete the filtration.
2. Dual tube switching mechanism
When a filtering unit experiences an increase in resistance and a decrease in efficiency due to the accumulation of impurities, there is no need to stop the machine. The material can be switched to another unit for further filtration through two three-way ball valves. At this time, the pollution unit can be cleaned or replaced with a filter to ensure continuous production and meet the long-term continuous production needs of pharmaceutical companies.
3. Single tube function expansion
If a single filtration unit is required, the common machine base can be removed while keeping the other dimensions unchanged to achieve single cylinder filtration, which has flexible scene adaptability and meets diverse production needs.
Stainless steel dual filter, with scientific structural design and efficient working principle, provides reliable filtration solutions for the pharmaceutical industry, helping enterprises to steadily improve product quality and ensure production continuity.
