Small laboratory filter, customized for you!

 The Laboratory filter press consists of a group of filter chambers composed of filter plates and filter frames arranged alternately. There are grooves on the surface of the filter plate, and its protruding parts are used to support the filter cloth. There are through holes on the corners of the filter frame and the filter plate. After assembly, a complete channel is formed, which can pass the suspension, washing water and lead out the filtrate. There are handles on both sides of the plate and frame to support the crossbeam, and the plate and frame are pressed by the clamping device. The filter cloth between the plate and the frame acts as a sealing gasket. The suspension is pressed into the filter chamber by the feed pump to form filter residue on the filter cloth until the filter chamber is filled. The filtrate passes through the filter cloth and flows along the grooves of the filter plate to the channel at the corners of the plate and frame, and is discharged in a centralized manner. After the filtration is completed, clean washing water can be introduced to wash the filter residue. After washing, compressed air is sometimes introduced to remove the remaining washing liquid. Then open the filter press to remove the filter residue, clean the filter cloth, re-press the plate and frame, and start the next working cycle

Features of laboratory filter press

●The material of the laboratory filter press machine can be polypropylene or stainless steel according to actual needs, which is corrosion-resistant and durable. This experimental filter press can achieve the purpose of sterilization by matching microporous filter membrane according to different filter media and production processes (primary filtration, semi-fine filtration, fine filtration). It can also reduce or increase the number of filter layers according to the size of the filtration volume to make it suitable for production needs. The sealing parts of this machine are made of medical silicone rubber or fluororubber, which has no leakage and good sealing performance. This machine has the advantages of good sealing, stable performance, convenient operation and maintenance, low filtration cost, long service life, high production efficiency, extended working time, convenient forward and reverse flushing, etc.

●The laboratory filter press can also be customized with multi-stage filtration devices according to user needs, with coarser filter materials in the first stage and finer filter materials in the second stage, which saves time and equipment and improves the filtration accuracy. The plate and frame filter with microporous filter membrane is currently the ideal equipment for filtering activated carbon and particles.

●The filter element of this filter adopts a skeleton-type all-stainless steel winding wedge structure, which is processed by stainless steel wire and central ribs. It has high precision, high strength and durability. It overcomes the shortcomings of the past disc candle type that is easy to deform and easy to clog. It is easy to discharge slag and clean, easy to install and replace. It is firm and not easy to damage, and has a long service life.

●No need to use filter cloth, no manual cleaning, clean and hygienic.

●Automatic filter candle cleaning: During backwashing, the backwash water forms a moving continuous water film on the inner surface of each filter candle. Through periodic compressed air (compressed air is treated) as power, the moving water film suddenly passes through the V-shaped gap and is rinsed clean, thereby completely removing diatomaceous earth and other residues attached to the surface of the filter candle.

●Equipped with a pre-coating circulation pump, the diatomaceous earth pre-coating evenly and quickly forms a stable filter layer.

●The system has few mechanical transmission parts during the whole process of filtration, drainage and CIP cleaning, and is easy to repair and maintain.

●The diatomaceous earth filter layer of the filtration system is stable and firm, the filtrate is clear and transparent, the production efficiency is high, the filtration cycle is long, and the production capacity can exceed the nominal production capacity.
