General Introduction
Filter press is a solid-liquid separation device that utilizes a specialized filter medium to exert a specific pressure on the substance, causing the liquid to seep out.
Types of Filter Presses: There are several types of filter presses, including plate and frame filter presses, chamber type filter presses, vertical filter presses, belt filter presses, and membrane filter presses.
The membrane filter press has found extensive applications in various fields requiring solid-liquid separation. It is regarded as a replacement for the conventional box filter press.
When the membrane filter press (MKFP) is used in sludge and sewage treatment, the moisture content of the filter cake can be as low as below 60%. Compared with the traditional box pressure filter, the solid content rate of the filter cake can be more than doubled. This significantly reduces the transportation cost of the filter cake. The filter cake can be directly sent to a power plant for combustion, truly transforming sludge into a resource and making sewage as clear as spring water. It can completely replace the box pressure filter.
Highlighting Membrane Filter Press
Superior Dewatering Performance: It offers a better dewatering effect, reducing the moisture content of the cake to within 20% - 30%.
Automation Options: Automatic functions such as automatic plate shifting, cake discharge, and cloth washing can be added.
Robust Frame Structure: The main material of the frame is carbon steel. It consists of carbon beams with seamless rectangular tube welding, which is resistant to special frame deformation, strong, and durable.
High Quality Filter Plates: The filter plates are made of pure polypropylene (PP), without any other fillers or recycled materials. They have high strength, are lightweight, corrosion-resistant, acid and alkali - resistant, non-toxic, and odorless.
Customizable Filter Cloths: There are various types of filter cloths available to suit different materials, enhancing the filtering accuracy.
Durable Faucets: The special faucets are made of polypropylene materials. They are formed by quick-opening molds, are strong and durable, and can withstand high temperatures, strong acids, and alkalis.
Technical Advantages
The belt filter press comes with the following characteristics: a compact structure, an innovative design, ease of maintenance and operation, a large processing capacity, a low moisture content in the filter cake, and excellent performance.
Comparing with other similar devices, it offers the following advantages:
Inclined Design of the First Gravity Filtration Section The first gravity filtration section is designed with an incline. This design keeps the sludge at a height of 1700 mm above the ground, effectively increasing the height of the gravity filtration section and enhancing its gravity-based filtering capacity.
Extended Gravity Filtration Section The gravity filtration section is relatively long. The combined length of the first and second sections reaches up to 5 m. This ensures that the sludge undergoes thorough dewatering before entering the pressing stage. Additionally, the gravity dewatering section is equipped with inversion devices. After passing through the wedge - shaped and S-shaped filtering processes, sludge with an extremely low moisture content can be obtained.
“T”-Type Draining Tank on the First Dewatering Roller The first dewatering roller is equipped with a “T”-type draining tank. This feature enables the rapid discharge of a large volume of water, thereby enhancing the dewatering effect.
Automatic Deviation - Prevention and Adjustable Filter Belt An automatic device is installed to prevent the filter belt from running off-track. The tension and moving speed of the filter belt can be freely adjusted, making the equipment easy to maintain and operate.
Low Noise and Vibration The belt filter press operates with low noise levels and minimal vibration. 6. Reduced Chemical Reagent Consumption It consumes a relatively low amount of chemical reagents.
