Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model pressurized air accurate filter.Wherein the direction of arrow is compressed-air actuated direct of travel.
Embodiment
1 describe the utility model in detail in detail in conjunction with the accompanying drawings below.
A kind of pressurized air accurate filter, comprise shell and installation filter core in the enclosure, shell is made up of upper end cap 2, lower end cap 3 and main casing 1, and upper end cap 2 and lower end cap 3 are removably connected to the top and bottom of main casing 1 respectively, and the bottom of lower end cap 3 is provided with drain valve.Main casing 1 is provided with suction port 12 and air outlet 13, is connected with filter core suction tude and filter core steam outlet pipe respectively; Set firmly one in the main casing 1 by upper sealing plate and the common filter core support of forming of lower annular plate, the filter core suction tude is connected on the upper sealing plate and with annular slab and is connected, and the filter core steam outlet pipe is L shaped bend pipe, passes upper sealing plate and links to each other with the air outlet.Be tightly connected between filter core steam outlet pipe and upper sealing plate; Filter core is formed the inboard of the annular slab that one-level filter core 4 is fixed in by three grades of filter cores of series connection; Secondary filter core 5 is wrapped on the outer ring of one-level filter core 4 and joins with the inner casing of main casing 1; Three grades of filter cores 6 are the annular core of top seal, and its underpart is fixed in the top of upper sealing plate, with upper half part corral of L type filter core steam outlet pipe interior.
In order to realize better filtering effect, one-level filter core 4 is rolled into cylindrical filter core for being pressed into wave by the Stainless Steel Wire interlacing, and secondary filter core 5 is a winding type cotton fiber net.Three grades of filter cores 6 are the annular mist of oil filter core of being made up of jointly outer glass fiber and inner nonwovens.
Drain valve can adopt automatic drain valve or manual drainage valve.Also automatic drain valve 7 and manual drainage valve 11 can be installed simultaneously, the waste pipe 10 of automatic drain valve 7 stretches out from the bottom of lower end cap 3 and connects by Sealing 8, nut 9, and manual drainage valve 11 is connected with internal thread interface on the lower end cap 3 outer casing bottom side positions by outside thread.
For ease of dismounting, upper end cap 2, lower end cap 3 can adopt with main casing 1 and be spirally connected or the buckle Placement.
During concrete work, pass through the suction port 12 of filter from the source of the gas pipeline from the pressurized air of air compressor, enter in the one-level filter core 4, by being pressed into wave by the Stainless Steel Wire interlacing when being rolled into cylindrical one-level filter core 4, in conjunction with the big or small water droplet that is contained in wherein, and form the water droplet of beans sizes with other dirts.The water droplet that is filtered out is regularly discharged by lower end cap 3 bottom automatic drain valves 7 drain opening, or manually discharges by lower end cap bottom manual drainage valve 11 drain opening.Because of filter core can reduce compressed-air actuated speed, thereby the utmost point is implemented air-water separation effectively.Utilize this one-level filter core 4 can remove about water droplet more than 95%.The annular secondary filter core 5 formed by the cotton fiber net that is connected with main casing 1 madial wall of pressurized air then by winding type, near airflow direction and the swirling eddy of change in the cotton fiber net or it, form whirlpool, this moment, air was accelerated tens times, and was formed centrally vacuum in whirlpool.The water droplet that one-level filter core 4 fails to remove is gasificated into herein has no dysgenic gas to machine.It is online that the remaining simultaneously big dirt and the dregs of fat also are filtered to cotton fiber.So 100% liquid water, the solid particle more than 5 microns is thoroughly got rid of.The three grade mist of oil filter cores 6 of last pressurized air by being connected with the upper sealing plate of central position in the main casing 1, mist of oil filter core 6 internal structures are made up of glass fibre layer (press part) and nonwoven layer (separator portion).When mist of oil in the pressurized air and solid particle are run into glass fibre layer; because of the not Brownian movement (referring to that the particle below 0.1 micron moves to the motion of all directions) that still causes of moving air fully; this particle can be run into and be attached on the fiber; though the solid particle that adheres to can not forever be removed; but the mist of oil that adheres to can be dirty along the mutual point of intersection of fiber; these aggregations form very big oil droplet gradually, flow to filter bottom.Utilize the continuous and air separation of this a series of effect.Be disposed at inboard nonwoven layer, can prevent that bigger oil droplet is inhaled in the air again because of air flows, can make oil droplet make the mist of oil deposition simultaneously with the gravity of self.But mist of oil in the filtering pressurized air and the solid particle more than 0.01 micron provide clean air.And when three grades of filter cores 6 are operated in the pressure range, even atmospheric temperature below zero degrees celsius, condensation can not take place yet.Filter efficiency improves greatly thus, and filter has longer working life, and after pressurized air filtered by three grades of filter cores 6, the greasy dirt impurity that is filtered was discharged by draining valve, and high quality pressurized air is exported by the air outlet.
The above is preferred embodiment of the present utility model only, is not that the utility model is done any pro forma qualification.Any change that is equal to, modification or differentiation etc. that all those skilled in the art utilize the technical solution of the utility model that the foregoing description is made all still belong in the scope of technical solutions of the utility model.
