Abstract
This utility model belongs to filter technology field, relate to Double-layer filter cartridge, it is provided with, on outer surface with the cylindrical stent of stainless steel material making, the drainage screen that one layer of stainless steel material makes, it has been spaced diamond hole on the sidewall of cylindrical stent, the area of the diamond hole of cylindrical stent is more than the mesh area of drainage screen, advantage is: cylindrical stent of the present utility model uses corrosion resistant plate to be drawn into stainless-steel sheet net, the mesh of stainless-steel sheet net is diamond hole, integrated cylindrical stent not only intensity is high, and filter area is big, filter efficiency is high, service life is long, the decay resistance of the drainage screen that employing 316L stainless steel silk is woven into, particularly pitting resistance is good, elevated temperature strength is high, it is applicable to V-type filter.
Description
Technical field
This utility model belongs to filter technology field, refers in particular to a kind of Double-layer filter cartridge.
Background technology
At present, the screen cloth that cartridge filter is monolayer that V-type filter uses, or in mesh grid or use corrosion resistant plate punching
The outer surface of the support formed is provided with one metal wire layer mesh grid, and it is disadvantageous in that: one is the entirety due to mesh grid
Intensity is low, is easily deformed, and is not suitable for high-pressure filteration；Two is that the filter area of support that corrosion resistant plate punching is formed is little, impact
Filter efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of intensity height, the Double-layer filter cartridge of good filtration effect.
The purpose of this utility model is achieved in that
Double-layer filter cartridge, the outer surface with the cylindrical stent of stainless steel material making is provided with one layer of stainless steel material system
The drainage screen made, the sidewall of cylindrical stent has been spaced diamond hole, and the area of the diamond hole of cylindrical stent is more than drainage screen
Mesh area.
Above-mentioned drainage screen stainless steel silk is knitted to form.
Above-mentioned stainless steel silk 316L rustless steel is made.
Above-mentioned cylindrical stent is the stainless-steel sheet net using corrosion resistant plate drawing and forming, and the mesh of stainless-steel sheet net is
Described diamond hole.
The filtering accuracy of above-mentioned drainage screen is 80-500 mesh.
This utility model highlights and useful having the technical effect that compared to existing technology
1, cylindrical stent of the present utility model uses corrosion resistant plate to be drawn into stainless-steel sheet net, the net of stainless-steel sheet net
Hole is diamond hole, and integrated cylindrical stent not only intensity is high, and filter area is big, and filter efficiency is high, and service life is long.
2, the advantage of the drainage screen that this utility model employing 316L stainless steel silk is woven into is: decay resistance, particularly
Pitting resistance is good, and elevated temperature strength is high, and service life is long.
3, this utility model is applicable to V-type filter.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, sees Fig. 1-Fig. 2:
Double-layer filter cartridge, the outer surface with the cylindrical stent 10 of stainless steel material making is provided with one layer of stainless steel material
The drainage screen 20 made, the sidewall of cylindrical stent 10 has been spaced diamond hole 11, the face of the diamond hole 11 of cylindrical stent 10
The long-pending mesh area more than drainage screen 20.
Above-mentioned drainage screen 20 is knitted to form with stainless steel silk.
Above-mentioned stainless steel silk 316L rustless steel is made.
Above-mentioned cylindrical stent 10 is with the stainless-steel sheet net of corrosion resistant plate drawing and forming, the mesh of stainless-steel sheet net
For described diamond hole 11.
The filtering accuracy of above-mentioned drainage screen 20 is 80-500 mesh.
Above-described embodiment is only preferred embodiment of the present utility model, limits protection model of the present utility model the most according to this
Enclose, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, protection of the present utility model all should be covered by
Within the scope of.
