Description

Compressed air oil filter

Technical field

The utility model relates to oxygenerator fields, more particularly to the oil screen that oxygenerator gas source is filtered.

Background technique

Medical molecular sieve oxygen generation system is to be divided the oxygen in air with nitrogen using molecular sieve principle of pressure swing adsorption From to oxygen producing, it has many advantages, such as that process flow is simple, take up little area, is with low investment, operates, easy to maintain, product oxygen Gas purity can be adjusted arbitrarily according to actual needs, and device adaptability is good.The continuous circulate operation of package unit can be completely achieved automatic Change.

When carrying out oxygen processed using molecular-sieve oxygen generator, need to be compressed gas source, prefiltration, oil removing, freeze-drying, Existing oil removing mode is filtered by Agglomerate Filter, and centrifugation oil removal process effect is poor, and accurate filter is caused to be inhaled Attached amount is big, is easy blocking, the replacement cycle is short, influences yield.

Utility model content

The purpose of the utility model is to overcome deficiency in the prior art, provide a kind of good deoiling effect, the operation is stable, Compressed air oil filter with long service life.

The utility model is achieved through the following technical solutions: a kind of compressed air oil filter, including cabinet, the case Body inner upper end is provided with downward runner, and runner upper end is provided with centrifugal impeller, and the air inlet of the centrifugal impeller connects upwards It is connected with air inlet pipe, the centrifugal impeller lower end is connected with collision disk by extension bar, and the collision disk is located at runner lower end exit, The runner lower end is additionally provided with oil collector sump tank, and the cabinet also passes through accurate filter and is connected with escape pipe.

Further, the flow channel cross-section is circle, and cross-sectional area of the runner close to upper end is greater than far from upper The area of section at end.

Further, the oil collector sump tank includes the Oil Guide ring for being set to runner lower end, is opened on the side wall of the Oil Guide ring There is oil guiding hole obliquely, the Oil Guide ring outer side seal is provided with collection chamber, and the collection chamber lower end surface is inclined-plane, the collection The lowest point of oil pocket is communicated with oil pipe, and the oil pipe extends to outside cabinet obliquely and is communicated with oil groove, and the oil groove is set to case On external wall, the oil groove lower end is provided with oil exit pipe.

Further, Oil Guide ring lower end is provided with tubaeform diffusion shell.

Further, strainer is additionally provided between the runner outer wall and cabinet wall.

Further, the collision disk upper surface is spherical.

The utility model has the beneficial effects that: setting centrifuge blade, compressed air forms high speed and revolves into centrifuge blade is crossed The air-flow turned, dust and mist of oil hit runner inner wall under the influence of centrifugal force and assemble；Cross section of fluid channel is wide at the top and narrow at the bottom, gas velocity Degree gradually increases, and centrifugal force increases, except speed oil is accelerated；Setting collision disk can make air-flow flow velocity between collision disk and runner It sharply increases；Greasy dirt can be collected and be exported by setting oil collector sump tank；Setting diffusion shell can be such that air velocity reduces, and avoid gas Cabinet same place is impinged upon in adfluxion, reduces noise.

Specific embodiment

The technical solution of the utility model is illustrated below in conjunction with specific embodiment.

Embodiment 1

As shown in Figs. 1-2, a kind of compressed air oil filter, including cabinet 1, cabinet 1 is enclosed by copper sheet to be made, by 3MPa Pressure test, good seal performance, and have bactericidal effect, 1 inner upper end of cabinet is sealed and installed with downward runner 2, runner 2 Section is downward taper, and runner 2 is surrounded by the steel plate of electroplating surfaces with tin, is equipped with centrifugation leaf on 1 inner wall of cabinet of 2 upper end of runner Wheel 3, the air inlet of centrifugal impeller 3 are communicated with air inlet pipe upwards, and 3 lower end of centrifugal impeller is connected with collision disk 5 by extension bar 4, touches It hits disk 5 and is located at 2 lower end exit of runner, collision 5 upper surface of disk is spherical, and 2 lower end of runner is also equipped with oil collector sump tank, oil-collecting Device includes the Oil Guide ring 6 that welding is installed on runner lower end, uniformly opens the oil guiding hole that haves three layers from top to bottom on the side wall of Oil Guide ring 6 12,3 layers of oil guiding hole 12 staggeredly open up, and each oil guiding hole 12 opens up obliquely, and 6 outer side seal of Oil Guide ring is equipped with collection chamber 8, collection 8 lower end surface of oil pocket is inclined-plane, and the lowest point of collection chamber 8 is communicated with oil pipe 13, and oil pipe 13 is extended to outside cabinet 1 obliquely and is communicated with Oil groove 9, oil groove 9 are installed on 1 outer wall of cabinet, and 9 lower end of oil groove is communicated with oil exit pipe 10, and 6 lower end of Oil Guide ring is equipped with tubaeform Diffusion shell 7, diffusion shell 7, Oil Guide ring 6,2 inner face of runner be continuous shiny surface.

Strainer 11 is also equipped between 1 inner wall of 2 outer wall of runner and cabinet, strainer 11 includes two layers of copper mesh, two layers of copper wire Filter cotton is filled between net.

Cabinet 1 is also connected with escape pipe by accurate filter 14.

The working principle of the present embodiment is as follows: compressed air enters runner by centrifugal impeller, forms high-speed rotating gas Stream, air-flow rotate downwards in runner, flow velocity quickening, moving radius reduction, under the influence of centrifugal force, dust, greasy dirt etc. compared with The impurity of bulky grain is assembled on flow path wall, then moves down under the action of gravity and airflow thrust, then passes through Oil Guide Device discharge, is filtered using strainer and accurate filter, reduces the content of greasy dirt and dust.
