The plate and frame filter press uses pressure difference and filter cloth filtration to separate the solid-liquid mixture. It is mainly composed of a frame, filtration, automatic plate pulling, hydraulic and electrical control parts. It has the advantages of good separation effect, wide application range, high degree of automation, energy saving and environmental protection. It is suitable for sludge dehydration in urban sewage treatment, pharmaceutical, electroplating and other industries. It is an ideal equipment for environmental management and resource recovery.

The plate and frame filter press uses the pressure difference between the plate and frame and the filtration effect of the filter cloth to separate the solids and liquids in the solid-liquid mixture. During the filtration process, by applying a certain pressure and forming a filter cake, Achieve efficient solid-liquid separation.

The filter press is mainly composed of five parts: frame part, filter part, automatic pull plate part, hydraulic part and electrical control part.

Working principle of plate and frame filter press

Pressing the filter plate: First, apply pressure through the hydraulic system to press the filter plate tightly to form a good sealing environment.

Feeding: The suspension to be treated is sent into the filter chamber through a feeding pump, and a filter cake is formed on the filter cloth, while the clear liquid flows out through the gap between the filter cloth and the filter plate to achieve solid-liquid separation.

Filter cake pressing: As the filter cake thickens, the filtration resistance increases. At this time, the pressure can be adjusted to maintain a stable filtration speed.

Filter cake washing: When washing is required, close the water outlet valve of the rinsing plate and open the water outlet valve of the pressure drying plate so that the rinse water can pass through the filter cake under pressure to achieve the washing effect.

Unloading: After the processing is completed, perform the cake unloading operation, that is, open the filter plate and remove the filter cake from the filter cloth.

In addition, the drainage methods of the plate and frame filter press are divided into two types: open flow and undercurrent. The open flow type means that the filtrate is directly discharged out of the machine through the water outlets on both sides of the plate and frame, while the underflow type means that the filtrate passes through the undercurrent of the plate frame and the rear roof. hole discharge.

The entire process realizes solid-liquid separation through pressure difference, which is widely used in solid-liquid separation scenarios in industrial production.
