Product Details
Product Introduction
Plate-and-frame filters are widely used and well suited for precision filtration involving clean oils, absorbents, lubricants, sludge dewatering, and other filtration media. They are particularly ideal for applications where no external mechanical power is available and where the filtration medium can readily enter the plate-and-frame assembly. This equipment features a simple design, low flow resistance, convenient operation, and broad applicability, making it a versatile filtration solution. In addition, plate-and-frame filters are frequently employed for solid–liquid separation of various suspensions. When the suspended particles are relatively large and present in limited quantities, combining filtration with sedimentation can effectively yield a clarified filtrate. For suspensions containing fine, similarly sized particles in substantial amounts, using a plate-and-frame filter—compared with sedimentation alone—can produce a clearer filtrate while significantly shortening the filtration cycle.
Working principle
The slurry is pumped into each sealed filtration chamber of the filter press. Under operating pressure, the filtrate passes through the filter membrane or other filtering medium and exits via the effluent outlet, while the filter cake remains within the frame, thereby achieving solid–liquid separation.
Product Features
1. The equipment is manufactured entirely from high‑quality SUS304 or SUS316L stainless steel, offering excellent corrosion resistance and long‑term durability. 2. The filter plates feature a threaded design, allowing users to select different filtration media and adjust the number of filtration stages—whether for preliminary, semi‑fine, or fine filtration—according to process requirements. By directly using microporous membrane filters, sterile filtration can be achieved. Additionally, users can customize the number of filtration layers based on the desired flow rate, ensuring optimal performance to meet production needs.
3. All sealing components utilize silicone rubber O-rings, which offer excellent high-temperature resistance, are non‑toxic, and provide superior sealing performance. 4. Custom multi‑stage filtration units can also be designed to meet specific user requirements: the first stage accommodates coarser filter media, while the second stage uses finer material, saving time and enhancing filtration accuracy. Moreover, the system is equipped with no backflow device, making temporary cleaning of the filter media exceptionally convenient. Once the pump has stopped, opening the backflow valve allows all accumulated deposits to be automatically discharged; subsequent rinsing with clean water through the backflow line thoroughly cleans the system.
5. The pump unit (or an explosion-proof motor, if applicable) and the inlet piping are connected using a quick‑release coupling, facilitating easy disassembly and cleaning.
