The filter press is a fully-automated system for sludge treatment, does not require operator assistance and in most cases, no additional chemicals are needed. The sludge is sent to every sealed filter chamber by the feeding pump with pressure, going into filter plates and filter cloths. The clean water will be filtered out from the filter plate water outlet by the filter cloth, but the solid is kept in the chambers to separate solid and liquid, finally, we will get the slurry cake to contain 25% water.
When the Filter press is operated, the sludge is discharged from the feed inlet into the filter cylinder and is moved to the discharge port by the push of the spiral shaft rotary vane. The pitch is gradually reduced, so the pressure of the sludge is also increased, and the pressure difference is started to be dehydrated, and the water is from the fixed ring and the activity.
The annular piece is filtered out of the gap, and the filter press depends on the self-cleaning function between the fixed plate and the movable plate, and the clearance between the filter and the filter is prevented from being blocked. After fully dehydrated, the discharge is discharged from the discharge port under the action of the propeller shaft.
1. Providing efficient cleaning support to sludge accumulated in wastewater.
2. The machine works on the principle of pressure feeding that provides for optimum output support.
3. Supports a reduction in moisture content of sludge significantly.
4. Working as the solid-liquid separation device, the system can also be custom tuned as per the specific work process needs of customers.
5.Suitable for dewatering low and high concentrated sludge.
The main function of the filter press type dewatering machine is to separate the solid matter from the liquid and dewater the sludge. It is composed of a frame, a filter plate, a filter cloth and a plurality of membrane-assembled parts for automatic operation.
When the mud is pressured to contact the filter cloth, the larger particles produce bridging filtration before the filter cloth holes (because the filter cake layer is the main character of the filtration, so it is called CAKE FILTRATION), and the solid matter is intercepted and stacked to form a filter cake layer. The liquid that penetrates the filter cake and the filter cloth in the mud is recovered or discharged as a filtrate; the filter cloth and the filter cake produce an impedance, and the pressure of the fluid must be higher than the increased impedance of the gradually thickened filter cake layer until the pressure filter The filter cake layer in the machine reaches a solid state, the filter plate will be pulled open and the filter cake removed.
The plate and frame filter press is the first machine used in chemical dehydration. Although the plate and frame filter press generally has an intermittent operation, the large investment in infrastructure equipment, and low filtration capacity, it has large filtration driving force, the high solid content of filter cake, clear filtrate, high solid recovery rate, and conditioning medicine. The advantages of low consumption and so on are still widely used in some small sewage plants.
The frame part is the main body of the machine to support the filter mechanism and connect other components. It is mainly composed of a thrust plate, a pressing plate, a cylinder block and the main beam.
The filtering part is composed of a filter plate arranged on the main beam in a certain order, a filter cloth sandwiched between the filter plates and a diaphragm filter plate.
Pull plate part
1. The automatic pull plate part
The automatic pull plate portion is composed of a hydraulic motor, a robot, a transmission mechanism, and a suspension device.
2. The manual pull plate part
Manually pull the plate to discharge the material.
A hydraulic part is a power unit that drives the pressing plate to press or loosen the filter plate and is equipped with a plunger pump and various control valves.
Electronic control part
The electronic control part is the control center of the entire system.
1. Corrosion-resistant rubber coated and reinforced thick steel plate material molding (SRRM) so that the filter plate can be long-lasting and non-deformable. Many manufacturers purchase the commercially available rubber-coated steel plate, which is not easy to deform.
2. PP polypropylene rafts should have sufficient support for the increase in strength of Stay Bosses, insufficient support or incorrect alignment, and reduced reinforcement.
