Introduction to Cartridge Filter

Description of Cartridge Filter

A cartridge filter is a type of precision filter composed of a shell and filter cartridges. It can be equipped with a single cartridge or multiple cartridges, the quantity of which is determined by the filtration flow rate. The shell consists of an upper head, a cylinder body and a cartridge base, featuring easy cleaning with no sanitary dead corners. 3D model online review.

Working Principle

During operation, different filter cartridges are selected according to various filtration media and design processes to meet the requirements of liquid output effect. Driven by pressure, the stock solution passes through the filter cartridges, the filter residue is retained on the cartridge wall, and the filtrate flows out through the cartridges, thus achieving the purpose of filtration.

Advantages

  1. Large processing capacity, small volume and high dirt-holding capacity.
  2. Wide application range, flexible use and diverse installation methods.
  3. Convenient and quick cartridge replacement, easy cleaning with no sanitary dead corners.
  4. The filtration precision ranges from 0.5 to 100 micrometers and can be adjusted freely.
  5. Excellent sealing performance, strong pressure-bearing capacity and low leakage probability, which effectively ensures the filtration quality.

Introduction to Bag Filter

Description of Bag Filter

A bag filter is a new-type filtration system. Inside the filter, the filter bag is supported by a metal mesh basket. It features a novel structure, excellent sealing performance and zero side leakage, along with a large effective filtration area, high filtration efficiency, convenient and quick filter bag replacement, and low operating costs.

Working Principle

The material flows into the filter bag from the inlet of the bag filter. Particles larger than the filtration pore size of the filter bag are trapped on the inner surface or inside the filter bag. The purified liquid passes through the filter bag from the inside out and flows out through the outlet of the bag filter.

Advantages

  1. Large processing capacity, small volume and high dirt-holding capacity.
  2. Wide application range, flexible use and diverse installation methods.
  3. Convenient and quick filter bag replacement, and the bag filter is maintenance-free without the need for cleaning.
  4. The filtration precision ranges from 0.5 to 600 micrometers and can be adjusted freely.
  5. Excellent sealing performance, strong pressure-bearing capacity and low leakage probability, which effectively ensures the filtration quality.

Description of Melt Blown String Wound Filter Cartridge

The melt blown string wound filter cartridge is a depth filtration element with excellent sealing performance. It is designed for filtering low-viscosity fluids with low impurity content, and can effectively remove suspended solids, rust, particles and other contaminants from the fluid, delivering outstanding filtration performance.

Working Principle

During operation, under external force, the liquid in the suspension passes through the filter cartridge equipped with a specified filter screen. Impurities are trapped by the cartridge, while the purified liquid flows out, thus achieving solid-liquid separation.

Advantages

  1. Broad chemical compatibility: Meets the requirements of various industrial processes.
  2. Graded pore structure: Features uniform pore distribution, high filtration efficiency, high dirt-holding capacity, and effective removal of particles of different sizes.
