What is a press filter and how does it work?
Filterpress filterpress is a device that performs the filtration process in a large volume and separates liquids and solids from each other. Filter presses are mainly filters under pressure, which are made of plates that are placed between a fixed plate and a moving plate connected to a hydraulic jack and are pressed together. The work of the filter press is to extract water from the slurry that has excess water.
🔰 Filter Press Components
1- The chassis of the filter press machine 2- The screen of the filter press device 3- The frame of the filter press machine 4- Jack and hydraulic unit of the filter press device
🔰 Types of Press Filter Devices
🔶 Manual press filter 🔶 Automatic filter press 🔶 Hydraulic press filter 🔶 Membrane press filter (variable volume) 🔶 Filter press chamber (constant volume)
🔰 How Filter Press Functions
In short, filter press function is defined in 5 steps: 🔹 Filtration: The slurry enters the filter press from above and the filtration process begins. 🔹 Compression: In the compression stage, to separate the remaining water from the slurry, air or water is introduced with high pressure to the back of the slurry so that the slurry chambers are under pressure. 🔹 Dehydration with air: In the step of dehydrating with air, due to the separation of the remaining water, air flow is blown into the cake. 🔹 Cake discharge: The plates containing the cake are spaced apart so that they can be easily removed from the filter press. Filter washing: Filters are washed with water to prepare for reuse.
🔰 Steps to make filter presses
🔹 Design, supply and preparation of steel and cast parts
🔹 Cutting of steel parts, which includes the arms of the filter press machine and the machining of the arms.
🔹 Flooring plates and frames
🔹 Drilling holes and installing handles on plates and frames
🔹 stone work of cast parts and quality control of parts in terms of the quality of cast parts
🔹 Assembling the arms and the initial and final parts of the filter press machine 🔹 Construction of hydraulic unit set Installing the hydraulic unit on the chassis 🔹 Assembly of plates on the chassis 🔹 Turning on the hydraulic system and testing different parts 🔹 Dismantling plates and hydraulic unit 🔹 reassembly and final test
