Description
Technical field
The invention belongs to filtering material and device field, relate to a kind of glass fibre sintered filter core.
Background technology
Filter element is the core component of filter plant, filter element is used primarily in oil filtration, air filtration, water filtration etc. and filters industry, solid particle in filter element separation liquid or gas, after fluid enters filter element, its impurity is blocked, and the stream thing cleaned is flowed out by filter element, liquid is made to reach certain cleanliness factorAir filtering coreMake the air that the is contaminated state by cleaning to producing, required for life.
The material of filter element is varied, there are the kinds such as paper filter core, chemical fibre filter element, metal filtering core, ceramic element, active carbon filter core, different filter elements has different features, in recent years, fiber sintering filter element is rapidly developed, it belongs to the one of chemical fibre filter element, it is to use specific fiber, add the filter element goods that binding agent, firming agent, stabilizer etc. obtain by heating thermal sintering, there is the characteristics such as micropore size is uniform, porosity is high, flux is big, water environment capacity is strong, mechanical strength is high, self-supporting performance is good, insoluble, molten.
Summary of the invention
It is an object of the invention to provide a kind of glass fibre sintered filter core, this filter element has the advantage that mechanical strength is high, self-supporting performance is good, filtering accuracy is high, can be applicable to oil and filters and water filtration industry.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of glass fibre sintered filter core, described filter element is hollow tubular body, described filter element includes outer coarse filtration fibrous layer (1), fine straining fibrous layer (2), interior coarse filtration fibrous layer (3) the most successively, described each layer is tubular, described each layer fibreglass sintering forms, described fine straining fibrous layer (2) is located between described outer coarse filtration fibrous layer (1) and interior coarse filtration fibrous layer (3), and described each layer is hot sticky is connected into an entirety.
The pore size filter of described fine straining fibrous layer (2) is less than outer coarse filtration fibrous layer (1) and the pore size filter of interior coarse filtration fibrous layer (3), and described outer coarse filtration fibrous layer (1) and interior coarse filtration fibrous layer (3) have identical pore size filter.
