The working principle of the frame filter:

Floating liquid is pumped into each sealed filter chamber of the filter machine. Under the action of working pressure, the filtrate passes through the filter membrane or other filter materials and is discharged through the outlet. The filter residue remains in the frame to form a filter cake, thus achieving the purpose of solid-liquid separation.

Characteristics of Plate and Frame Filters:

1. Corrosion resistant and durable.

2. The filter plate adopts a threaded mesh structure, which can replace different filter materials according to different filtration media and production processes (primary filtration, semi fine filtration, fine filtration) requirements. The purpose of sterile filtration can be achieved directly by using microporous membrane. Users can also reduce or increase the number of filtering layers according to the size of the filtering volume, making it suitable for production needs.

3. All sealing components are made of silicone rubber sealing rings, which are heat-resistant, non-toxic, leak free, and have good sealing performance.

4. The pump (or explosion-proof motor can be used) and input pipe components of the plate and frame filter adopt quick installation connection, which is easy to disassemble and clean. Plate and frame filters have a large filtration area, high flow rate, and a wide range of applications, so they are widely used in industries such as pharmaceuticals, chemicals, and food. They are applied in the filtration of injection drugs in pharmaceutical factories and have excellent results.

Except for the motor, all other components of the plate and frame filter are made of high-quality corrosion-resistant stainless steel materials, suitable for filtering various pH and acidic solutions. The plate and frame filter should be pressurized and sealed for filtration, with low loss of filtrate, good filtration quality, and high efficiency. The filtration section consists of nine layers of filter plates, with a large filtration area and high flow rate; And according to the different production processes (primary filtration, semi fine filtration, fine filtration) requirements of the filtered solution, different filter membranes can be replaced, and the number of filter plate layers can be appropriately reduced or increased according to the user's production flow rate to meet production needs. Therefore, the plate and frame filter has the characteristics of one machine for multiple uses and a wide range of applications; The filter plate adopts a flat threaded mesh shape with advanced structure, no deformation, easy cleaning, which can effectively increase the service life of various filter membranes, thereby reducing and saving production costs. The plate frame filter is equipped with a stainless steel infusion pump, which is equipped with a small motor and consumes less power.
