Working principle and application characteristics of plate and frame filter

Plate and frame filter is a kind of filtering equipment It is suitable for the closed filtration of the liquid with lower viscosity and less slag under 50% concentration to achieve the requirements of purification, sterilization, clarification and other fine filtration and semi fine filtration The purpose of sterile filtration can be achieved directly without microporous membrane filter Working principle: the floating liquid is pumped into each closed filter chamber of the filter Under the action of working pressure, the filtrate is discharged through the filter membrane or other filter materials through the outlet, and the filter residue is left in the frame to form filter cake, so as to achieve the purpose of solid-liquid separation The plate and frame filter is a stainless steel multi-layer plate and frame filter press, which is suitable for the closed filtration of the liquid with lower viscosity and less slag content under 50% concentration to achieve the requirements of purification, sterilization, clarification and other fine filtration and semi fine filtration The microporous membrane can be directly selected to achieve the purpose of sterile filtration without directly connecting the microporous membrane filter Features 1 Corrosion resistance, durable 2 The filter plate adopts the thread strong structure According to the requirements of different filter media and production process (primary filter, semi fine filter and fine filter), different filter materials can be replaced and the purpose of sterile filtration can be achieved by directly using microporous filter membrane Users can also reduce or increase the number of filtering layers according to the size of filtering volume, so that it can meet the production needs 3 All sealing parts are made of silicone rubber sealing rings, which are high temperature resistant, non-toxic, leak free and have good sealing performance 4 The pump (or explosion-proof motor) and input pipe parts of the plate and frame filter are connected by quick installation, which is convenient for disassembly and cleaning The plate and frame filter has a large filtering area, large flow and wide application range, so it has a wide range of applications in pharmaceutical, chemical, food and other industries, and it is applied to the filtration of pharmaceutical injection liquid medicine in pharmaceutical factories with good results The plate and frame filter is made of 1Cr18Ni9Ti corrosion-resistant stainless steel except for the motor It is suitable for filtering various pH value acid-base solutions The plate and frame filter is pressurized and sealed, with less filtrate loss, good filtering quality and high efficiency The filtering part is composed of nine filter plates, with large filtering area and large flow volume According to the requirements of different production processes (primary filtration, semi fine filtration and fine filtration) of the filtered solution, different filter membranes can be replaced, and the number of filter plates can be appropriately reduced or increased according to the production flow of the user, so that it can meet the production demand Therefore, the plate and frame filter has the characteristics of one machine, multi-purpose and wide application range; The filter plate adopts the flat thread net shape, with advanced structure, no deformation and easy cleaning, which can effectively increase the service life of various filter membranes, thus reducing and saving the production cost The plate frame filter is equipped with stainless steel infusion pump, with small motor and power consumption Application: plate and frame filter is widely used in pharmaceutical, biochemical, food and beverage, water treatment, brewing, petroleum, electronic chemical industry, electroplating, printing and dyeing, environmental protection and other industries It is a new Zui equipment for filtration, clarification and purification of various liquids
