Automatic Cleaning Industrial Filter Press Plate And Frame Diaphragm Filter Press Chamber

The Fully Automatic Box-Type Diaphragm Filter Press Reduces The Moisture Content Of The Municipal Wastewater ​

Device overview
The plate and frame turbidizer is the first machine used for chemical dehydration. Although the plate and frame mud press is generally operated intermittently, the investment in infrastructure equipment is large, and the wave passing capacity is also low, due to its
It has the advantages of large filtration discharge power, high solid content of filter bamboo, filtrate purification, high solid recovery rate, and low consumption of conditioning drugs. It is still widely used in Yisheng Small Sewage Plant.
After the sludge is concentrated and digested, there is still a moisture content of about 95% to 97%, and the volume is still large. Sludge dewatering allows one-step removal of empty yard water and capillary water in the sludge, reducing its volume.
After dehydration treatment, the moisture content of sludge can be reduced to 70%-80%, and its volume is 1/10-1/4 of the original volume, which is beneficial to subsequent transportation and treatment. Sludge mechanical dewatering is the method of filtering water,
Centrifugal dehydration and bowl-pressing dehydration, etc., filter dehydration and vacuum filtration and pressure filtration: centrifugal dehydration is dehydration with a centrifuge;
Dehydration. The most commonly used methods are pressure river oil and centrifugal joy water. The oil-passing dehydration of the sludge is based on the pressure difference between the two sides after passing through the medium as the driving force, so that the sludge moisture is forced to pass through the oil-passing medium.
The filtrate is formed by the filtrate, and the solid particles are trapped on the medium to form a filtrate, so as to achieve the dehydration of the river mixture.
dehydration process
The plate and the frame are arranged alternately: there are filter cloths on both sides of the filter plate, and the plate and the bar are compressed by the pressing device, that is, the filter press chamber is formed between the plate and the frame. In the middle of the upper end of the plate and the frame
A small white hole is opened in the same part, and after pressing, it becomes a channel, and the sludge pressurized to 0.2-0.4MPa enters the filter press chamber through this channel. The surface of the filter plate is engraved with white grooves, and the bottom end is drilled to supply the liquid.
The discharged channel, under the pressure of the liquid, passes through the filter cloth, and is discharged from the filter along the groove and the channel, so that the sewage is deeply dehydrated. Kuang Neihui has developed a dynamic plate-type filter press. Plate and Frame Pressing Machine Bio
The air filter can withstand higher sludge specific resistance, so that the consumption of conditioner can be significantly reduced, and cheaper agents (such as FeS04.7H20) can be used. When the sludge ratio is 5x|011-
When 8xIC1 is 2m/kg, it can be filtered directly without preconditioning. The mud cake yield and mud cake moisture content of the plate and frame filter press should be determined according to test data or similar operating experience.
The moisture content of mud pieces can generally be 75% to 80%.
