6-Branches Vacuum Filtration Manifold
Hawach Scientific co., LTD. is specialized in the development, production, sales and service of teaching instruments, experimental instruments, medical instruments, and analytical instruments, and in the production of multi-branches vacuum filtration manifold professional manufacturers.
6-branches glass vacuum filtration manifold is made of high-quality silicate, can bear hot pressure disinfection, flange mouth is fine grinding, compact performance reasonable structure, beautiful appearance, surface bright and clean, easy to clean, corrosion-resistant, easy to use, durable. It is the equipment used by colleges and universities, scientific research institutes, pharmaceutical factories, and hospitals to filter bacteria, microorganisms, and particles as culture medium, blood products, and liquid medicines.
The vacuum filtration method utilizes a pressure difference formed between the atmospheric pressure and the generated vacuum to overcome the resistance of the filter layer and performs a water filtration clarification process, which is commonly used for sludge drying.
The vacuum drum filter used in production generally has a vacuum of 300-500 mm Hg, and the rotating speed of the drum is about one to several revolutions per minute. The filter cloth is usually made of wool or nylon. The filtration capacity is 10-40 kg/(m2h) dry mud, the thickness of the cake is 5-10 mm, and the water content is 70-80%. Less floor space, but with high operating costs.
Vacuum filtration process
Generally, the vacuum filter is used to rotate the cylinder to form a filter cloth, and a radial fan-shaped compartment is arranged in the crucible, and the rotary valve is operated to make each compartment pressurize or decompress. The sludge is dehydrated under reduced pressure, and a mud cake is formed on the filter cloth, and the mud cake and the dirt adhering to the filter cloth are separated during the pressurization.
