Working Principle of High Pressure Diaphragm Filter Press<\/strong><\/h3>\n1, the frame is the foundation of the whole set of equipment, it is mainly used to support the filtering mechanism, by the thrust plate, compression plate, seat, cylinder body and the main beam and other connecting components. When the equipment is running, the piston rod on the cylinder body pushes the compression plate, and presses the diaphragm plate, filter plate and filter cloth located between the compression plate and the thrust plate, so as to ensure that the filter slurry with pressure is pressurised and filtered inside the filter chamber.<\/p>\n
2. The filtering part consists of diaphragm filter plate, chamber filter plate and filter cloth sandwiched between them, which are neatly arranged on the main beam. At the beginning of filtration, the filter slurry enters into the filter chamber through the inlet of the thrust plate under the push of the feed pump, and the slurry is separated from the solid-liquid with the help of the pressure generated by the feed pump, and the solids stay in the filter chamber to form the filter cake due to the action of the filtering medium (filter cloth) and the filtrate is discharged from the liquid discharge valve.<\/p>\n
3, the hydraulic part is the host to complete the pressure and release action of the power unit, under the action of the electrical control system, through the cylinder, oil pump and hydraulic components to complete a series of work in the system: when the system is pressed, the various chambers will be sealed for filtration; conversely, when loosened, for unloading.<\/p>\n
4\u3001The unloading mechanism is mainly composed of two gear motors, transmission shaft, sprocket, chain and other components. When the pressure plate is loosened, the motor at the position of the support seat starts, pulling the cylinder seat and pressure plate through the sprocket and chain, and pulling away the filter plate, the motor at the position of the thrust plate starts, driving the spacer to pull away the second part of the filter plate, and then through the signal in the electric control cabinet, the motor reverses, driving the spacer to pull away the rest of the filter plate, in this way, the process of a discharging is completed.<\/p>\n
5, the electrical control part is the control centre of the whole system, which is mainly composed of electric control cabinet, circuit breaker, air switch, contactor, intermediate relay, PLC (programmable controller), travel switch, proximity switch and TD200 text display, etc., which can automatically control the whole filter-pressing cycle.<\/p>\n
Scope of application<\/h3>\n
Filter press is widely used in sludge dewatering treatment of urban domestic sewage, textile printing and dyeing, electroplating, papermaking, leather, brewing, food processing, coal washing, petrochemical, chemical, metallurgical, pharmaceutical, ceramic and other industries, and is also suitable for solid separation or liquid leaching process of industrial production. Sudong sand washing filter press products mainly include sand washing diaphragm filter press and sand washing chamber filter press, the treated slurry can meet the standard for reuse, and the filtered sludge is directly transported for secondary use.<\/p>\n
