The high-efficiency filter for the compressed air is excellent in both structural strength and filtering performance and long in service life.
Description
Technical field
The utility model relates to a kind of compressed air high efficiency particulate air filter.
Background technology
Compressed air is a kind of very important power source, and is safe, powerful and reliable, is widely used in a plurality of industrial trades fields such as electronics, integrated circuit, semiconductor, chip, automobile, medicine, chemical industry, metallurgy, weaving.Yet if compressed air is untreated, a large amount of pollution impurity that it contains will influence the manufacturing.Air pollution impurity is mainly: solid particle, oil, water, if they are not removed, they mix, and will form the very strong acid greasy filth of a kind of corrosivity, corrode process equipment fast, influence the quality of product, cause production procedure to interrupt, paralyse.
The source of solid particle mainly contains three aspects: atmosphere, the wearing and tearing of compressor moving component and pipeline.Oil is extremely important in compressor, plays sealing, lubricated and cooling effect, adds and also contains oil content in the atmosphere, so contain considerable oil content in the air of compressor outlet.The content of water in air steam is very big, and with temperature direct relation is arranged, and a lot of products and equipment are all very sensitive to water in making and using.Exactly because this three big impurity that pollutes is arranged in the compressed air, if they are not purged, harm will very big, solution is to filter with filter, but there is insufficient strength in present filter, service life defective such as weak point.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide the compressed air high efficiency particulate air filter of a kind of intensity height, long service life, and the stainless (steel) wire intensity of this filter is big, and the light aluminum alloy shell is anti-oxidant, the filter capacity of glass fibre filter course is strong, long service life.
For achieving the above object, the technical solution of the utility model is: a kind of compressed air high efficiency particulate air filter, comprise shell and installation filter core in the enclosure, it is characterized in that: described filter core comprises upper and lower end cap and middle filter course, described upper end cover is provided with the outstanding position that lock ring " O " ring of sealing, described filter core is through being connected with the upper shell of shell at outstanding position, and described filter course is respectively interior stainless (steel) wire, interior fiber cloth structure sheaf, glass fibre filter course, outer fiber cloth structure sheaf, outer stainless (steel) wire from inside to outside and prevents the entrained layer of splashing.
The connected mode of the upper shell of described filter core and shell is a center double-screw bolt screw-threaded coupling mode.
The material of described shell is the light aluminum alloy through the antirust processing of chromate.
The material of described glass fibre filter course is a boron silicon acid glass fine fibre.
The material of the described entrained layer that prevents to splash is a sponge.
Described compressed air high efficiency particulate air filter also is equipped with automatic water trap, differential pressure indicator differential pressure indicator.
Compared with prior art, the utlity model has following advantage: the light aluminum alloy shell, through the antirust processing of chromate, the long-time use do not played oxidation reaction; Boron silicon acid glass fine fibre filter course, the impurity capture space not only increases flow, reduces pressure drop up to 96%, and life-saving; Inside and outside stainless (steel) wire props up lining, and the ability of the tolerance fluctuation pressure of filter core is greatly improved.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the organigram of the utility model filter core.
The specific embodiment
With reference to figure 1 ~ 2, a kind of compressed air high efficiency particulate air filter, comprise shell 1 and be installed in filter core 2 in the shell 1, it is characterized in that: described filter core 2 comprises upper end cover 21, bottom end cover 22 and middle filter course, described upper end cover 21 is provided with the outstanding position 211 that lock ring " O " ring 23 of sealing, described filter core 2 is through being connected with the upper shell 11 of shell 1 at outstanding position 211, and described filter course is respectively interior stainless (steel) wire 24 from inside to outside, interior fiber cloth structure sheaf 25, glass fibre filter course 26, outer fiber cloth structure sheaf 27, the outer stainless (steel) wire 28 and the entrained layer 29 that prevents to splash.Stainless (steel) wire 24, outer stainless (steel) wire 28 make the ability of tolerance fluctuation pressure of filter core improve greatly in described, fiber cloth structure sheaf 25, outer fiber cloth structure sheaf 27 play the bracing reinforcement effect in described, avoid glass fibre to be subjected to the impact of air-flow, fibr tissue is torn, and glass fiber is fractureed.
In order to increase structure of filter intensity, described filter core 2 is a center double-screw bolt screw-threaded coupling mode with the connected mode of the upper shell 11 of shell 1, and described filter core 2 bottoms are stressed, and gasproof stream impact capacity is strong, and the location cooperates firmly, and sealing is reliable.
The material of described shell 1 is the light aluminum alloy through the antirust processing of chromate, and long-time the use do not played oxidation reaction.
The material of described glass fibre filter course 26 is a boron silicon acid glass fine fibre, and the impurity capture space not only increases flow, reduces pressure drop up to 96%, and life-saving.
For the adsorbed oil particle water, the material of the described entrained layer 29 that prevents to splash is high density, high-intensity sponge.
Described compressed air high efficiency particulate air filter also is equipped with automatic water trap, differential pressure indicator differential pressure indicator.
The course of work of the present utility model: the profit particles hit in the compressed air constantly is caught to the glass fibre of filter core 2, gathers then and grows up, skin toward filter core 2 under the promotion of air-flow is walked, and enters and prevents to splash entrained layer 29, is adsorbed by sponge, if do not have retardance and the absorption of sponge, the moisture of established larger particles, effect of inertia strikes shell 1 inwall, pulverize, atomizing becomes fine particle again once more, enters the downstream with air-flow; Walked downwards under the effect of gravity by the profit that sponge is received, near the bottom end cover 22 of filter core 2, form a humid zone 291.Profit in the housing accumulates to a certain amount of back automatic water trap and opens valve according to the time of setting, and profit just is discharged from filter.The particle that particle diameter is bigger has just entered the glass fibre laminar surface of filter core 2, has been booked at once; When particle hour because glass fibre is random weave in, particle has still bumped against on the glass fibre of back at last; When grain diameter more hour, when it is walked with gas, also have the molecular motion phenomenon, its motion equivalent path non-constant width that becomes, the glass fibre in this path domain just can be caught impurity.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
