Product Description

Vacuum Filter System

Vacuum Filter is a fully automatic filtration system, which can filter low viscosity oil or emulsion liquid with vacuum operation. Most application is nonferrous metal production like steel, cast iron, Aluminum and so on. 

 

Main Structure

  • Clean liquid tank
  • Dirty liquid Tank
  • Sludge Box
  • Vacuum/suction tank

 

Filtration Process:

On vacuum filter, the liquid to be filtered enters into an integrated sump, where it is pumped into a filtration area. The filtration bed provides additional inches of gravir pull. The two sides of the filters have seals to prevent bypassing of filter media. The stock removal that builds on the filter media creates a “cake”, which provides additional filtration and makes the filtration rate more accurate. Meanwhile the filtration speed is getting more slowly and more vacuum.

When the clean liquid reaches a certain level and a certain vacuum, it automatically transport the media, the dirt filtration paper and slugs will be moved forward to slug box. Dirty filter paper will be replaced by clean filter paper automatically, another filtration circle starts.

 

FEATURES

  • Compact structure, easily installation
  • Fully automatically to reduce operation cost
  • No stop to ensure a continues production
  • High Vacuum and high filtration rate to have lower consumption of filter paper
  • Can design acc. to customer flow rate
