Abstract
The invention discloses a rotary type compressed air filter which is characterized in that an annular alternating flow channel is formed on the outer side of the compressed air filter to enable compressed air to form turbulent flow and remove most of liquid moisture and oil mist in the compressed air under the action of centrifugal force. The inner side of the compressed air filter is filled with a quantitative efficient oil-water absorber, and a perforated plate is fixed at the upper end of the compressed air filter. The rotary type compressed air filter mainly plays colliding and absorbing roles on the compressed air filter entering the inner side through the alternating flow channel formed on the outer side of the compressed air filter, further removes a trace of residual liquid moisture and oil mist in the compressed air and accordingly improves pre-filtering efficiency of the compressed air.
Description
Technical field
The present invention relates to a kind of gas-filtering device, relate to specifically a kind of rotary type compressed air filter.
Background technology
Filter is to utilize physical barrier technology to carry out a kind of equipment of other compositions in separating medium.Air cleaner is for aerosol class impurity such as solia particle, water droplet and mist of oils in filtered air, makes air obtain clean capital equipment.
There are two macrotaxonomies in air cleaner, a class is the air cleaner for surrounding air clean technology, plays key effect in fields such as air conditioning, clean room, workshops, and this class filter is to work near atmospheric pressure substantially.Equations of The Second Kind filter is mainly used in pipeline air, i.e. compressed-air actuated purification in pneumatic system, and this class filter working pressure range is very large, is not pressed onto a hundreds of atmospheric pressure not etc. from several atmosphere, is referred to as compressed-air filter.
There is not substantive difference from the above-mentioned two class air cleaners of physical essence, but due to the difference of filtering object and working environment, make it to exist larger difference in the application such as version, handling characteristics.
The air cleaner of narrating herein belongs to Equations of The Second Kind, i.e. compressed-air filter.The filtering object of compressed-air filter is the compressed air of carrying through pipeline, after overcompression, the physical property of air has had obvious variation, for example, temperature, pressure, density, specific enthalpy etc. all improve and corresponding increase with pressure, and specific volume declines inversely with pressure; After compression, in unit gas volume, impurity concentration improves greatly simultaneously, air compressor machine exhaust is conventionally in saturation state and be mixed with a large amount of liquid water droplets, the solid-state tar that pneumatics process produces, liquid mist of oil and oil vapour content have increased by tens to hundred times than the natural air sucking, and all these make compressed air become genuine visceral-qi.
The task of compressed-air filter is exactly to filter out targetedly all pollution impurity that steam is thought, its user's professional span is very large, they vary to the requirement of source of the gas cleanliness factor, and therefore on complex art, compressed-air filter is much more comprehensive, complicated than a class filter.
Summary of the invention
Goal of the invention: in order to improve the preposition filter efficiency of compressed air, the invention provides a kind of easy for installation, lower-cost rotary type compressed air filter.
Technical scheme: for achieving the above object, the invention provides a kind of rotary type compressed air filter, be characterized in that compressed-air filter outside forms annular alternation runner, make compressed air form turbulent flow and under centrifugal action, remove compressed air in most liquid moisture and mist of oil.Compressed-air filter inner side is filled with a certain amount of high efficiency oil-water absorber and has porous plate to fix and compressed-air filter upper end, its Main Function is compressed air collision and the absorption that alternation runner outside compressed-air filter is entered to inner side, further remove the liquid moisture of trace remaining in compressed air and mist of oil, thereby improved the preposition filter efficiency of compressed air.
As a preferred embodiment of the present invention, compressed air inlet port is positioned at rotary filter exterior annular alternation runner upper end, air bleeding valve is positioned at lower end, rotary filter bottom, and high efficiency oil-water absorber is positioned at rotary filter inner side, and porous plate is positioned at high efficiency oil-water absorber top.Described filter also comprises filter housing, rotary filter bottom air inlet.
Beneficial effect: rotary type compressed air filter provided by the invention can effectively be removed liquid water droplets in compressed air, mist of oil impurity, the preposition filter efficiency of raising filter and easy for installation, with low cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1, rotary filter 2 is positioned at filter housing 5 inside, and compressed air inlet port 3 is positioned on filter housing 5 and with rotary filter 2 annular alternating flow roads, upper end and is communicated with.Rotary filter bottom air inlet 6 is communicated with the high efficiency oil-water absorber 4 of rotary filter 2 inner sides, and air bleeding valve 7 is positioned at rotary filter 2 lower ends, bottom, and porous plate 1 is positioned at high efficiency oil-water absorber 4 tops.
Compressed air is from compressed air inlet port 3 inflow filters, flow into annular alternation runner lower end by rotary filter 2 outer upper end annular alternation runners, most liquid moisture and mist of oil in making its formation turbulent flow and remove compressed air in compressed air trickling process under centrifugal action, now pretreated compressed air enters into rotary filter 2 inner sides by rotary filter bottom air inlet 6, pass through again collision and the absorption of high efficiency oil-water absorber 4, further remove the liquid moisture of trace remaining in compressed air and mist of oil, then flowed out by filter upper porous plate 1.And the water droplet filtering, mist of oil impurity are flowed out by air bleeding valve 7 timings that are positioned at rotary filter 2 lower ends, bottom.
After measured, rotary type compressed air filter provided by the invention can effectively be removed liquid water droplets in compressed air, mist of oil impurity, the preposition filter efficiency of raising filter and easy for installation, with low cost.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
