Produced by PPH vacuum filtration tank manufacturerworking principle

The PPH vacuum filtration tank extracts the air inside the tank through a vacuum pump, creating a negative pressure environment lower than the external atmospheric pressure. After the liquid containing solid particles is poured into the tank, the external atmospheric pressure pushes the liquid through the filter cloth, and the solid particles are trapped on the surface of the filter cloth to form a filter cake. The liquid then passes through the filter cloth into the bottom of the tank and is discharged through the drain outlet. As the filtration progresses, the thickness of the filter cake increases and needs to be cleaned regularly to maintain filtration efficiency. The vacuum state can lower the boiling point of liquids and is suitable for filtering high boiling point substances, while accelerating the speed of liquid passing through the filter cloth and improving overall processing capacity.

Application advantages

Efficient separation: Vacuum negative pressure drives the liquid to quickly pass through the filter cloth, with a filtration speed superior to gravity or pressurized equipment, shortening the production cycle.

Cost optimization: PPH material is cost-effective and corrosion-resistant, with a long equipment lifespan and reduced frequent replacement costs; The filter cloth can be reused, reducing the cost of consumables.

Environmental compliance: solid-liquid separation reduces the content of harmful substances in wastewater, helps enterprises meet environmental discharge standards, and avoids punishment risks.

Flexible operation: The vacuum degree and filter cloth aperture can be adjusted according to the properties of the liquid to meet the filtration needs of materials with different concentrations and viscosities.

Easy maintenance: The tank body has no complex mechanical components, and daily cleaning only requires washing the filter cloth and residual materials inside the tank; Regularly inspecting the vacuum pump and seals can ensure stable operation.

Produced by PPH vacuum filtration tank manufacturerPrecautions for use

Installation inspection: Before use, carefully check whether the fasteners in each part are loose to ensure that the suction volume and vacuum degree are not affected.

Operating standards:

Before starting the vacuum pump, ensure that the connection is well sealed to avoid air leakage.

Reasonably control the operating pressure based on the pressure bearing capacity and liquid characteristics of the filter membrane to prevent membrane blockage or damage.

Maintenance and upkeep:

Regularly clean the filter membrane and choose chemical cleaning, physical cleaning, or ultrasonic cleaning according to the blockage situation.

Regularly maintain the vacuum pump, such as replacing lubricating oil, cleaning the pump body, and checking the seals.

Safety protection: Wear protective equipment during operation to prevent contact with corrosive liquids or inhalation of harmful gases.
