Specific implementation mode

It please refers to Fig.1 shown in -4, the utility model is about a kind of accurate breath filter core, including filter body 1, stainless steel Filter screen 2, the filter body 1 are cylindrical in shape, and the upper and lower ends of filter body 1 are respectively gas outlet 11 and air intake 12, the filter core The inside of body 1 by stainless steel filter screen 2 along filter body 1 length direction even partition be six layers of filter layer, and filter layer by Under it is supreme respectively fill haydite 3, coarse filtration cotton 4, activated carbon 5, middle filter cotton 6, alumina particle 7, fine filtering cotton 8.

Filter cotton can be divided by national standard (GB/T14295)：Slightly it is (first) effect, it is middle effect, efficiently, can be divided by Europe superscript：G1,G2, G3,G4,F5,F6,F7,F8。

Slightly (first) effect filter cotton (air port cotton) main filtration is more than 5 μm of dust particle, is generally used for ventilation equipment and sky At gas control system suction inlet as pre-filtering or coarse filtration etc. directly and outdoor air contact place；Also it is chiefly used in board-like mistake Filter folds leaf filter, the filtrate of the Filters such as bag filter.Primarily efficient filter wool can also be used in air feed system make Pre-filtering under being exposed for high dust；The pre-filtering supplied in paint finishing and apparatus for baking and current balance function filtrate material and spy Property.

Medium air filtration cotton (top cotton) main filtration is more than 1 μm of dust particle, is generally used for slightly imitating two after filtering Grade or ultimate filtering, are also chiefly used in the filtrate of leaf filter.

High efficiency filter cotton is mainly used in the extra high environment of the filtering requirements such as hospital or laboratory.

Arrow direction of the air in Fig. 1 is entered by the man-hole opening of 1 lower end of filter body inside filter body 1, and by passing along warp Each layer stainless steel filter screen 2 in haydite 3, coarse filtration cotton 4, activated carbon 5, middle filter cotton 6, alumina particle 7, fine filtering After cotton 8, it is discharged from the gas outlet 11 of 1 upper end of filter body, therebetween, each filter layer is filtered air.

The filtration of the utility model using by pass it is fine by the way of, effectively pass through the hole of haydite 3 itself capture Visible foreign in air, activated carbon do fine filtering, and aluminium oxide does drying, in addition by reasonable effective collocation of thin filter cotton, To achieve the purpose that clean gas.

Specifically, the filtering precision of the stainless steel filter screen 2 is fine by passing from the bottom to top.

Using the above scheme, stainless steel filter screen 2 using by pass it is fine by the way of, it is miscellaneous that every layer of filtering is effectively isolated Matter, to reach best filter layer effect.

Specifically, the upper end fixing sleeve of the filter body 1 is equipped with filter core ring flange 9, and filter core ring flange 9 is circumferentially uniformly opened Equipped with flange screw hole.

Using the above scheme, 1 upper end of filter body setting filter core ring flange 9, filter core ring flange 9 opens up flange screw hole, with It will pass through filter core ring flange 9 and flange screw hole and coordinate screw, filter body 1 is fixed on the filter.

Specifically, further include upper network blocking lid 10, upper 10 detachable cover of network blocking lid is closed in the gas outlet of filter body 1 11.

Using the above scheme, the upper lid of network blocking lid 10 is closed in the gas outlet of filter body 1 11, can further stop the miscellaneous of air Matter, and can disassemble at any time to clean the impurity of accumulation.

Specifically, the filter body 1 is made of the ABS materials of high intensity.

Using the above scheme, filter body 1 is made of the ABS materials of high intensity, and non-toxic and tasteless, impact strength is fabulous, resistance to Excellent, the good stability of the dimension of mill property, service life are long.

Specifically, the filter body 1 is integrally formed with filter core ring flange 9.

Using the above scheme, filter body 1 uses mold injection one-pass molding, simple in structure, manufacturer with filter core ring flange 9 Just, suitable for mass production.

Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine It protects in range.
