Abstract
The utility model discloses a rotary compressed air filter. The rotary compressed air filter is characterized in that a ring alternating passageway is arranged on the outer side of a compressed air filter, so compressed air forms turbulent flow and eliminates majority liquid water and oil mist in the compressed air under the function of centrifugal force. Certain amount of effective oil water adsorbers are filled in the inner side of the compressed air filter. A multi-hole plate is fixed on the upper end of the compressed air filter. The main function of the rotary compressed air filter is to crash and adsorb the compressed air which enters the inner side of the compressed air filter through the alternating passageway from the outer side of the compressed air filter, and then further eliminates remained small amount of the liquid water and the oil mist and improves preposition filter efficiency of the compressed air.
Description
Technical field
The utility model relates to a kind of gas-filtering device, relates to a kind of rotary compressed-air filter specifically.
Background technology
Filter is to utilize the physical barrier technology to come a kind of equipment of other compositions in the separating medium.Air cleaner be used for aerosol class impurity such as solia particle in the filtered air, water droplet and mist of oil, make air obtain the capital equipment of cleaning.
There are two macrotaxonomies in air cleaner, and one type is the air cleaner that is used for the surrounding air clean technology, plays key effect in fields such as air conditioning, clean room, workshops, and this type filter is near atmospheric pressure, to work basically.Second type of filter then is mainly used in the pipeline air, i.e. compressed-air actuated purification in the pneumatic system, and this type filter working pressure range is very big, is pressed onto a hundreds of atmospheric pressure from several atmosphere and does not wait, and is referred to as compressed-air filter.
Say that from physical essence there is not substantive difference in above-mentioned two types of air cleaners, but because filtering object and working environment different make it in applications such as version, handling characteristics, to exist bigger difference.
The air cleaner that this paper narrated promptly belongs to second type, i.e. compressed-air filter.The filtering object of compressed-air filter is the compressed air of carrying through pipeline; The physical property of air has had obvious variation after overcompression; For example, temperature, pressure, density, specific enthalpy etc. all improve and corresponding increase with pressure, and specific volume then descends with pressure with being inversely proportional to; Impurity concentration improves greatly in the compression back unit gas volume simultaneously; The air compressor machine exhaust is in saturation state usually and is mixed with a large amount of liquid water droplets; The solid-state tar that the pneumatics process produces, liquid mist of oil and oil vapour content have increased by tens to hundred times than the natural air that sucks, and all these make compressed air become genuine visceral-qi.
The task of compressed-air filter is exactly to filter out all pollution impurity that steam is thought targetedly; Its user's industry span is very big; They vary to the requirement of source of the gas cleanliness factor, and therefore compressed-air filter is much more comprehensive, complicated than one type of filter on complex art.
The utility model content
The utility model purpose: in order to improve the preposition filter efficiency of compressed air, the utility model provides a kind of rotary compressed-air filter easy for installation, lower-cost.
Technical scheme: for realizing above-mentioned purpose; The utility model provides a kind of rotary compressed-air filter; Be characterized in that the compressed-air filter outside forms annular alternation runner, make compressed air form turbulent flow and under centrifugal action, remove most liquid moisture and mist of oil in the compressed air.The compressed-air filter inboard is filled with a certain amount of efficient profit absorber and the fixing and compressed-air filter upper end of porous plate is arranged; It mainly acts on is to getting into inboard compressed air collision and absorption through compressed-air filter outside alternation runner; Further remove micro-liquid moisture and mist of oil remaining in the compressed air, thereby improved the preposition filter efficiency of compressed air.
A kind of preferred version as the utility model; 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 efficient profit absorber is positioned at the rotary filter inboard, and porous plate is positioned at efficient profit absorber top.Said filter also comprises filter housing, the rotary filter bottom air inlet.
Beneficial effect: the rotary compressed-air filter that the utility model provides can effectively be removed liquid water droplets in the compressed air, mist of oil impurity, the preposition filter efficiency of raising filter and easy for installation, with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
Fig. 1, rotary filter 2 are positioned at filter housing 5 inside, and compressed air inlet port 3 is positioned on the filter housing 5 and with annular alternating flow road, rotary filter 2 upper ends and is communicated with.Rotary filter bottom air inlet 6 is communicated with rotary filter 2 inboard efficient profit absorbers 4, and air bleeding valve 7 is positioned at lower end, rotary filter 2 bottom, and porous plate 1 is positioned at efficient profit 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 runner; In compressed air trickling process, make its formation turbulent flow and under centrifugal action, remove most liquid moisture and mist of oil in the compressed air; This moment, pretreated compressed air then entered into rotary filter 2 inboards by rotary filter bottom air inlet 6; Pass through the collision and the absorption of efficient profit absorber 4 again, further remove micro-liquid moisture and mist of oil remaining in the compressed air, flow out by upper filter part porous plate 1 then.And the water droplet that is filtered, mist of oil impurity are then regularly flowed out by the air bleeding valve that is positioned at lower end, rotary filter 2 bottom 7.
Through measuring, the rotary compressed-air filter that the utility model provides can effectively be removed liquid water droplets in the compressed air, mist of oil impurity, the preposition filter efficiency of raising filter and easy for installation, with low cost.
The above only is the preferred implementation of the utility model; Be noted that technical staff for the present technique field; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
