Described air deflector is 120 degree " V " shape air deflectors.
Described secondary filter net is the ring-type screen pack, the centre bore sealing of ring-type screen pack.
Described gas outlet is provided with grease proofing filter core.
Outer basifacial symmetry at tank body is respectively arranged with form.
Oil immersed type filter of the present utility model has following outstanding beneficial effect: be provided with the V-arrangement air deflector and can play the effect of branch to water conservancy diversion in inner core, the top of air deflector is provided with deflection plate can better tackle impurity; Because the position of gas outlet makes air-flow intensive at the middle part of secondary filter net, the secondary filter net is set as ring-type and the centre bore sealing, can prevent that the secondary filter net from stopping up; Be provided with at gas outlet place grease proofing filter core further the minute impurities in the filtered air obtain the purest gas.
Description of drawings
Accompanying drawing 2 is plan structure schematic diagrames of oil immersed type filter.
Description of reference numerals: 1 inner core, 2 air deflectors, 3 guide vanes, 4 deflection plates, 5 lower carriages, 6 secondary filter nets, 7 upper brackets, 8 grease proofing filter cores, 9 gas outlets, 10 annular oil-recovery tanks, 11 grooves, 12 annular slabs, 13 first oil return pipes, 14 second oil return pipes, 15 tangential admission mouths, 16 oil fillers, 17 forms, 18 oil-outs.
The specific embodiment
Explain below doing with reference to Figure of description 1,2 pairs of oil immersed type filters of the present utility model of accompanying drawing.
Oil immersed type filter of the present utility model comprises tank body, and the top of tank body is provided with gas outlet 9, and the lateral surface bottom of tank body is provided with tangential admission mouth 15, and the another side of tank body is provided with oil filler 16 and oil-out 18.Middle and lower part in the tank body is provided with an inner core 1, the top of described inner core 1 and the inwall of tank body are fixed together by an annular slab 12, inner core 1 outer wall and annular slab 12 form a groove 11, groove 11 places are provided with first oil return pipe 13, the upper end of first oil return pipe 13 is connected on the annular slab 12, the lower end extends to the below of inner core 1, be provided with air deflector 2 in the described inner core 1, be provided with guide vane 3 around the air deflector 2, guide vane 3 plays the effect of eddy flow for flabellum shape, one end of guide vane 3 is fixed on air deflector 2 edges, the other end is fixed on the inwall of inner core 1, the top of described inner core 1 is provided with deflection plate 4, be provided with secondary filter net 6 above the deflection plate 4, secondary filter net 6 is between upper bracket 7 and lower carriage 5, and deflection plate 4 forms an annular oil-recovery tank 10 with the trapezoidal side of lower carriage 5, and the side of annular oil-recovery tank 10 is provided with second oil return pipe 14.
Described air deflector 2 is 120 degree " V " shape air deflectors, can play the effect of branch to water conservancy diversion.。
Described secondary filter net 6 is the ring-type screen pack, and the centre bore sealing of ring-type screen pack because the position of gas outlet 9 makes air-flow intensive at the middle part of secondary filter net 6, can prevent that secondary filter net 6 from stopping up.
Described gas outlet 9 is provided with grease proofing filter core 8, and further the minute impurities in the filtered air obtains the purest gas.
Outer basifacial symmetry at tank body is respectively arranged with form 17, can observe the height of pasta by form 17, and the height of normal pasta is in the position of form 17 cross central lines.
During work, air enters inner core 1 bottom by tangential admission mouth 15 horizontal direction tangent lines, obtain rotation and impact pasta downwards, make pasta generation fluctuation and started oily foam by air-flow, sky G﹠O foam mixes the back and utilizes the viscosity of oil that dust in air, impurity are glued in the oil, utilizes the oily foam formation oil droplet that gravity principle will adsorb impurity to fall the tank body inner bottom part simultaneously.Make progress through air deflector 2 through the higher air of another part oil concentration after the oil immersion, guide vane 3 produces interception and rotation, airborne most of oil content and fine solid particle are separated, get rid of in the groove 11 at inner core 1 edge, get back to the grease chamber, bottom by second oil return pipe 14, through the air after guide vane 3 de-oilings, continue upwards through deflection plate 4 resistance shelves oil content interception impurity, gas rises to 9 places, gas outlet after filtering through secondary filter net 6 again, grease proofing filter core 8 through 9 places, gas outlet further removes by filter fine impurity, the oil content that is separated at last flows in the annular oil-recovery tank 10 and flows to the tank body inner bottom part through first oil return pipe 13 again, obtain very clean gas at last, enter compressor by gas outlet 9.
Oil immersed type filter for molten of the present utility model has the filtering accuracy height, the pressure loss is low, noise is low, efficiency of dust filtration is high, can frequent clean not change filter owing to piling up grit impurity, greatly reduce the maintaining expense, reduced the characteristics such as air compressor fault rate.
