Anti corrosion PPH vacuum filtration tank

Working principle of anti-corrosion PPH vacuum filtration tank

Vacuum formation: The vacuum pump continuously extracts air from the tank through a vacuum tube, making the internal pressure lower than the external atmospheric pressure.

Filtering process: 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 is intercepted to form a filter cake. The liquid enters the bottom of the tank and is discharged through the drain outlet.

Continuous operation: As the filter cake thickens, regular cleaning is required to maintain filtration efficiency; Vacuum state can lower the boiling point of liquids and accelerate filtration speed.

Performance Characteristics

Strong corrosion resistance: PPH material can resist the corrosion of chemical substances such as acid, alkali, and organic solvents, and adapt to complex working conditions.

High temperature resistance: The softening temperature can reach 150 ℃, and it can be safely used for a long time below 100 ℃, meeting the needs of high temperature filtration.

Stable structure: The cylinder body is integrally formed, with a seamless design to avoid leakage risks, and has high impact resistance and tensile strength.

Long lifespan: With proper use, the lifespan can exceed 20 years, and under harsh conditions, it can still ensure stable operation for more than 10 years.

Easy maintenance: No complex mechanical components, daily cleaning only requires rinsing the filter cloth and residual materials in the tank, and regular inspection of the vacuum pump and seals.

Anti corrosion PPH vacuum filtration tankPrecautions for use

Medium matching: Before use, it is necessary to confirm the compatibility between the liquid composition and PPH material to avoid corrosive substances exceeding the equipment's tolerance range.

Temperature control: The operating temperature should be below the PPH softening point to prevent deformation of the tank due to high temperatures; In winter, it is necessary to empty the liquid in the tank to prevent freezing and damage.

Pressure management: Regularly check the performance of the vacuum pump to ensure stable pumping rate; Avoid excessive pressure fluctuations inside the tank that can affect the filtration effect.

Filter cloth maintenance: Select the appropriate pore size filter cloth according to the size of solid particles, clean or replace it regularly to prevent blockage; Avoid using strong acids and alkalis during cleaning.

Safety protection: Operators need to wear protective gloves and goggles to prevent liquid splashing; Emergency flushing devices should be installed around the equipment to respond to unexpected situations.
