Manual Filter Press - Economic Choice & Small Capacity

Manual filter press is one kind of intermittent pressure filter used for solid-liquid separation of various suspending liquids. It is suitable for filtering in industries with small scale, which needs low filter pressure (≤ 0.4 MPa). With manually closing the filter plates and discharging cakes, manual filter press has low cost, easy operation and high filtration efficiency. It belongs to testing machine with small input quantity when used in laboratory. It is widely used in chemical industry, metallurgy, coal washing, pharmacy, food and other industries that need excellent filtered results.

Manual filter press is operated by rotating the hand wheel to press the plates, so as to feeding and filtering.

Manual filter press components
Manual filter press is mainly composed of three parts: frame, filtration part and pressing section. When operating the filter press, rotates the hand-wheel through the pinion and bull wheel, driving the guide screw to impel the compaction board. It presses the filter plate and filter medium (filter cloth) tightly to guarantee pressure filtration in filter chamber for filtered material (slurry) carried with working pressure.

• Frame: The frame forms foundation of filter press, which supports the filtration organization and connects with other parts. It is mainly composed of the thrust plate, compaction board, compaction device and main beam.
• Filtration part: It is composed of filter plates and filter cloths, forming several filtering units (filter chambers). Filter plates are arranged in a certain order on the main beam.
• Pressing section: It is the power unit of manual filter press. The major components include pinion, bull wheel, guide screw, etc.

Manual filter press classification
There are two kinds of manual filter presses:

• Manual hydraulic pressing filter press.
• Manual mechanical pressing filter press.

Working principle
As the filtering process begins, the slurry is pushed into each filter chamber through the feeding port of thrust plate under the impetus of feeding pump. The filter medium (filter cloth) retains the particles in the filter chamber, which forms into filter cake, while the filtrate is drained through the water nozzle (open delivery) or the fluid channel (closed delivery). Inject wash liquid through washing port of the thrust plate, if filter cake washing is needed.
