SDN filter thickener

Generation 4(B)

Main feature

· Thread installation and double-end fixing of titanium-based metal filter element

· Mixing flange flange also serves as maintenance manhole

· The top is connected with the clearing and summarizing pipe

· Positive pressure/negative pressure cleaning

Main advantages

1. Advantages of the same metal filter element

2. The bottom blade ensures that the material liquid does not sink to the bottom

3. The equipment is small in size

Main process

No intermediate kettle

 Reaction kettle → Feed pump → 4 generation machine → Reaction kettle 

There is an intermediate kettle

 Reaction kettle → Intermediate kettle → Feed pump → 4 generation machine → Reaction kettle 

Introduction to filter elements of SDN thickener

01 Productive process

Industrial high purity metal powder as raw material, by high pressure pressing, high temperature sintering production. Joints are welded with inert gas protection without any adhesive.

02 Material characteristics

a) It is the first to prepare membrane materials by Kirkendall effect caused by partial diffusion between elements;

b) Reaction synthesis technology can realize precise regulation of pore structure at micron/submicron level, uniform pore size distribution of materials, high filtration accuracy, high open porosity, small tortuosity factor and small filtration resistance;

c) The unique mixed bond crystal form of "metal bond + covalent bond" combines the advantages of metal and ceramic materials, and has excellent chemical stability, thermal stability, mechanical and physical properties, machinability, thermal conductivity and electrical conductivity;

d) Material preparation process, environmental protection, friendly life cycle, recyclable and cost-effective.
