Brief Introduction of Filter Press

The chambe filter press is a technologically advanced separation machinery product that integrates machinery, electricity and hydraulics. lt consists of five parts: frame part, filter part (filter plate, membrane plate, filter cloth), pullingplate part, hydraulic part and electrical control part.

The frame part is the main body of the machine, used to support the filter mechanism and connect other components. lt is mainly composed ofthrust plate, pressing plate, cylinder block and main beam.

The filtration part is composed of filter plates aranged on the main beam in a certain order, filter cloth sandwichedbetween the filter plates, and membrane (membrane models have) filter plates. The filter plates and filter cloths (andmembrane filter plates) are arranged altemately to form several independent filter units - filter chambers.

The automatic pulling plate part consists of a variable frequency motor (hydraulic motor, manipulator,transmissionmechanism and pause dewice.

The hydraulic part is the power device that drives the pressing plate to press or loosen the filter plate. t is equippedwith a plunger pump and various control valves.

The electronic control part is the control center ofthe entire system.

Features

It is easy to operate and maintenance as the filter press is compressed by the hydraulic jack system and mechanical locking.

The maximum filtering (squeezing) pressure is 4.0 Mpa(40 Bar).

The filter press adopts the reinforced PP filter plates. The filter plate featured in high strength, light weight, anti-corrosive, acid and alkaline resistant, non-toxic and odorless is molding pressed with patent technology.

The frame of filter press is weld steel structure with stable mechanical performance, delicate type and attractive appearance.

The filter press can be configured with related auxiliary systems. It can be equipped with a mobile device, achieving automatic pulling of the board. It can be equipped with a filter cloth rapping device to completely remove the filter cake. It can be equipped with a filter cloth cleaning device, which automatically cleans the filter cloth and improves filtration efficiency. The choice of auxiliary system depends on the specific needs of the user.

The filter press is equipped with an electronic control system, achieving automatic control of operating procedures.

Working Principle of  Filter Press

The working principle of a filter press involves several steps, that are part of a filtration cycle. Let’s explore each step in detail:

Filtration cycle

The filtration cycle of a filter press consists of four stages: filling, filtration, cake formation, and cake discharge.

Filling the filter chambers

In the first stage, the filter chambers are filled with slurry, a mixture of solid particles and liquid. Pumping the slurry into the filter press causes the liquid to flow through the filter media, leaving the particles behind.

Filtration and cake formation

Once the filter chambers are filled, pressure is applied using the hydraulic system. This pressure forces the liquid to pass through the filter cloths, while the solid particles accumulate on the filter plates, forming a cake.

Cake discharge

After the filtration stage, the filter press is ready for cake discharge. The cake is removed from the filter plates either manually or automatically, depending on the type of filter press.
