Description
Technical field
The present invention relates to a kind of automatic oil return and manual oil return Multifunctional oil mist resistant filter, be mainly used for house vacuum pump or
Air compressor mist of oil exhaust filtering.
Background technique
In use, the gas of exhaust outlet discharge can have the lubricating oil of pump for vacuum pump or air compressor etc.,
This lubricating oil is combined together with gas, is in mist of oil state, if in the exhaust outlet uneasiness charge of oil mist resistant filter of vacuum pump, this
Kind can pollute indoor environment with the gas of mist of oil, cause damages to people's health, therefore, the exhaust outlet of vacuum pump is usually all
Oil mist filter need to be installed to reach clean-up effect.Applicant once devised a kind of oil mist filter, and had applied Chinese special
Benefit, patent No. ZL201621299798.5, including shell and it is mounted on the intracorporal filter core of shell, it is characterised in that the shell is adopted
Upper housing and lower case is made with plastic material, is respectively formed with connection sheet and clamp in the oral area of upper and lower casing, is made in connection sheet
There is a card slot, card slot is in contact cooperation with clamp, and described filter core one is formed with air inlet openings, and other end is sealing plate, in air inlet
Gasket is set between opening and lower case, spring is installed between sealing plate and upper housing.But in actual use, work as lower casing
It, cannot effectively quickly since the oil-returning structure of prior art is simple (only one oil return hole) when internal lubricating oil puts aside excessive
Lubricating oil is expelled back into the fuel tank of pump by ground, leads to oil spilling, or filter core lower part is caused to be immersed in lubricating oil, leads to effectively mistake
Filtering surface product reduces.
Summary of the invention
The purpose of the invention is to overcome prior art, provide a kind of using automatic oil return and dual manual row
Oil, the auto-manual oil return oil mist filter for avoiding the lubricating oil of savings from overflowing.
The technical solution of auto-manual oil return oil mist filter of the present invention is: including upper housing and lower case, upper and lower casing
Between filter core is set, upper housing is equipped with outlet interface, and the lower part of lower case is formed with intake interface, oil return is arranged at intake interface
Mechanism, it is characterised in that the oil return mechanism includes that annular convex platform is arranged on lower case inner bottom surface, is formed in annular convex platform
Vertical oil return hole and cross scavenging hole is arranged in the bottom of lower case in oil groove, and the inner end setting in cross scavenging hole is automatic to return
Hydraulic fluid port, automatic oil return mouth are connected to vacuum pump fuel reserve tank, and automatic seal oil oil return mechanism, cross scavenging hole are equipped in automatic oil return mouth
Outboard end manual back leakage connection is set, manual back leakage connection is by oil pipe connection vacuum pump fuel reserve tank, the one of intake interface
Outage is arranged in side, and shut-off valve is arranged in outage.
The invention discloses a kind of auto-manual oil return oil mist filter, it is mainly characterized by that oil return machine is arranged in lower case
Structure, the oil return mechanism include that annular convex platform is arranged on lower case inner bottom surface, oil groove are formed in annular convex platform, in lower casing
Vertical oil return hole and cross scavenging hole is arranged in the bottom of body, and automatic oil return mouth, automatic oil return is arranged in the inner end in cross scavenging hole
Mouth connection vacuum pump fuel reserve tank, is equipped with automatic seal oil oil return mechanism in automatic oil return mouth, and the outboard end in cross scavenging hole is arranged
Manual back leakage connection, manual back leakage connection connect vacuum pump fuel reserve tank by oil pipe, and outage is arranged in the side of intake interface,
Shut-off valve is set in outage, and in an inactive state, the lubricating oil put aside in oil groove passes through vertical oil return hole, cross scavenging
Hole and automatic oil return mouth continue the oil return into the fuel tank of pump.Pump when working long hours, quickly put aside by the lubricating oil in oil groove,
Depending merely on automatic oilhole cannot timely and effectively discharge, manual back leakage connection openable at this time, by oil pipe to tank drainback, in time
The lubricating oil for reducing savings, avoids lubricating oil from overflowing.And when not working, the shut-off valve in outage can also be opened, it is right
The lubricating oil put aside in oil groove is discharged, is cleared up, and makes the lubricating oil that do not deposit in oil groove, prolonging service life of filter elements is kept away
Exempt from oil accumulation spilling, guarantees that oil mist filter works normally.
Auto-manual oil return oil mist filter of the invention, is arranged spring between the filter core and upper housing, filter core exists
After a period of use, the mesh of filter core is once obstruction, can make the pressure rise in filter core, push the spring, after spring is compressed,
It is disengaged with lower case, the gas with mist of oil is directly entered in lower case and is discharged by the outlet interface of upper housing, spring
It plays using safe effect, prevents filter core barrier gas that can not be discharged and vacuum pump is caused to burst.The lower case lower part
Open-work is arranged in side, and column frame is arranged in open-work, and lens are arranged in open-work, can be put aside by lubricating oil in lens inspection lower case
Amount, grasps situation at any time, is convenient for oil extraction.Sealing ring is embedded on the annular convex platform, ring packing is arranged in the lower bottom part of filter core
Plate, annular seal plate is in sealing contact with sealing ring, guarantees that the gas with mist of oil is not discharged out of shell directly.The automatic sealing package
Oily oil return mechanism, which is included in automatic oil return mouth, is arranged flaring, and O-ring is arranged in flaring, valve plate is arranged on O-ring, pacifies under valve plate
Pressure spring is filled, pressure spring is mounted on hollow end and covers, and when work, by the gas pressure of vacuum pump, valve plate is withstood on O-ring, automatic to return
Hydraulic fluid port sealing blocks, and when not working, depresses pressure spring by the weight of valve plate itself, and (the elastic force very little of pressure spring), valve plate is fallen,
Oil return opening automatic oil return.
Detailed description of the invention
Fig. 1 is auto-manual oil return oil mist filter structural schematic diagram of the present invention；
Fig. 2 is automatic seal oil oil return mechanism schematic diagram of the invention.
Specific embodiment
The present invention relates to a kind of auto-manual oil return oil mist filters, as shown in Figure 1 and Figure 2, including upper housing 1 and lower casing
Filter core 3 is arranged between upper and lower casing for body 2, and upper housing 1 is equipped with outlet interface 21, and the lower part of lower case 2 is formed with intake interface
5, oil return mechanism is set at intake interface, and the oil return mechanism includes setting annular convex platform 15, ring on 2 inner bottom surface of lower case
Oil groove 14 is formed in shape boss, and in the bottom of lower case 2, vertical oil return hole 6 and cross scavenging hole 7, cross scavenging hole 7 are set
