Be connected respectively with the chamber of drier I and chamber II, the dust-filtering module include dust-filtering ontology, upper plane and under
Plane.The invention forms dizzy galvanic electricity field, and fume purifying efficiency greatly improves, and filter effect is good, and easy to clean, convenient disassembly makes
It obtains smoke particle and obtains repeatedly charged and reduction, so that detergent power greatly improved, the simple and reliable property of structure is high, repairs
It is also very convenient with replacing.
Although above-mentioned patent and a kind of device for removing oil mist removing, it mainly makes smoke particle using dizzy galvanic electricity field
Repeatedly charged and reduction is obtained, so that detergent power greatly improved.And the utility model is that air compressor is discharged
High pressure gas with mist of oil.By the mist of oil flow-guiding channel that plug valve, solenoid valve and oil mist filter are formed, and in mist filtration
It flows into oil storage tank and is recycled after being filtered in device.Therefore, the utility model in principle and structure all with foregoing invention
Patent is different.
Utility model content
Technical problem to be solved by the utility model is: how the band that safe and environment-friendly recycling is discharged from air compressor
Mist of oil in the high pressure gas of mist of oil.
Needle with the above problem, the utility model proposes technical solution be: a kind of mist of oil filtering device of air compressor,
Including valving, silencer, oil mist filter and oil storage tank, valving is connected to the side of oil mist filter upper end, disappears
Sound device is connected to the other side of oil mist filter upper end, and the lower end of oil mist filter is connect with oil storage tank.
Further, the exhaust end of one end of valving and air compressor connects, the other end and oil of valving
The air inlet side of mist resistant filter upper end connects, and valving and oil mist filter are interconnected.
Further, valving includes plug valve and solenoid valve, one end of plug valve and the exhaust end of air compressor
Connection, one end of solenoid valve are connect with plug valve outlet side, and the other end of solenoid valve and the air inlet side of oil mist filter upper end connect
It connects；And it is interconnected between plug valve, solenoid valve and oil mist filter.
Further, plug valve is check valve, from air compressor be discharged gas can from plug valve successively to solenoid valve,
Oil mist filter one-way flow, solenoid valve are normally open solenoid valve.
Further, silencer is the gas side that goes out for being connected to oil mist filter upper end, and silencer and oil mist filter it
Between be interconnected.
Further, removable mist filtration element, the lower end of oil mist filter and storage are filled in oil mist filter
Oil tank connection.
The utility model has the advantages that:
1. silencer is connected to the outlet side of oil mist filter, the band mist of oil being discharged from air compressor can be significantly eliminated
High pressure gas pass through the whistle generated when oil mist filter, so that noise pollution be greatly lowered.
2. drawing mist of oil gas using exporting in air compressor compression chamber, through controlling solenoid valve control, release to mist of oil
The mode of filter filtering discharge, can solve air compressor unloading time length simultaneously and mist of oil reveals asking for pollution atmosphere
Topic.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment one；
In figure: 1 plug valve, 2 solenoid valves, 3 silencers, 4 oil mist filters.
Specific embodiment
The description of a step is done to the utility model below with reference to embodiment and attached drawing:
Embodiment one
As shown in Figure 1, the mist of oil filtering device of air compressor includes plug valve 1, solenoid valve 2, silencer 3, mist of oil mistake
Filter 4 and oil storage tank.The inlet end of plug valve 1 and the exhaust end of air compressor connect, the outlet side of plug valve 1 and solenoid valve
