Description

Vavuum pump external oil mist filter

Technical field

The utility model relates to a kind of oil mist filter, particularly relates to one and does not limit by assembly space, can ensure again the vavuum pump external oil mist filter of mist filtration effect simultaneously.

Background technology

What during vavuum pump work, its exhaust outlet was discharged is the mist of oil of air-fuel mixture, these mist of oils produce surrounding enviroment and pollute, therefore vavuum pump needs the discharge of strict control mist of oil when the industries such as medical treatment and vacuum food packaging use, existing method is generally set up oil mist filter at the exhaust outlet of vavuum pump, oil mist filter by Assembly of the parts such as clips on the exhaust outlet of fuel tank, oil gas filters through oil mist filter when discharging, but the inner space of this kind equipment is often very compact, therefore the filter core size determined in oil mist filter is subject to certain restrictions, thus directly affect the filter effect of oil mist filter.

Utility model content

It is simple that the utility model mainly provides a kind of structure, restriction not by assembly space during installation, the vavuum pump external oil mist filter of mist filtration effect can be ensured again simultaneously, solve the inner space due to equipment existed in prior art to limit, cause the filter core size in oil mist filter less than normal, thus directly affect the technical problem of the filter effect of oil mist filter etc.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of vavuum pump external oil mist filter, comprise filter base and be located on filter base, downward opening tubbiness filter core, filter housing is covered with outside filter core, described filter base is provided with admission line and Oil Guide pipeline, the inner port of admission line is positioned on filter base corresponding to filter core mesopore, the external port of admission line is connected on the exhaust outlet of vavuum pump by flexible inlet pipe, the inner port of Oil Guide pipeline is positioned on filter base corresponding between filter core with filter housing, the external port of Oil Guide pipeline is connected in the discharge chamber of vavuum pump by elasticity oil return pipe.Change traditional hard connecting mode that oil mist filter is directly connected with vacuum pump oil box, oil mist filter is flexible coupling by flexible inlet pipe and elasticity oil return pipe and vavuum pump, because flexible inlet pipe and elasticity oil return pipe carry out length adjustment according to requirements, and can bend arbitrarily, oil mist filter can be installed other clearance space position in a device thus, structure is simple, make the filter core of oil mist filter can accomplish suitable size according to the requirement of performance, thus effectively ensure that the performance of oil mist filter, also make assembling more flexible and convenient.

As preferably, described admission line and Oil Guide pipeline all L-shaped, the admission line of L shape and the longitudinal pipe vertical connection of Oil Guide pipeline are on the end face of filter base, and the admission line of L shape is communicated with on the outer ring surface of filter base with the transverse pipe level of Oil Guide pipeline.The admission line of L shape and Oil Guide pipeline, easily process, and is also convenient to the abutting joint of flexible inlet pipe and elasticity oil return pipe.

As more preferably, the transverse pipe of described admission line and the transverse pipe of the Oil Guide pipeline coaxially relative both sides being positioned at admission line.When admission line and Oil Guide pipeline are oppositely arranged, be convenient to the installation of flexible inlet pipe and elasticity oil return pipe and the connection between oil mist filter and vavuum pump.

As preferably, the external port of described admission line and Oil Guide pipeline is connected with right angle Pneumatic quick connector respectively, and admission line and Oil Guide pipeline were connected on flexible inlet pipe and elasticity oil return pipe respectively by right angle Pneumatic quick connector.Right angle Pneumatic quick connector, as standard component, is easily purchased, and cost is low, and when flexible inlet pipe and elasticity oil return pipe were connected on flexible inlet pipe and elasticity oil return pipe by right angle Pneumatic quick connector, connected mode was simple and reliable.

As preferably, described flexible inlet pipe and elasticity oil return pipe are PVC transparent sebific duct.PVC transparent sebific duct cost is low, good springiness.

Accompanying drawing illustrates:

Fig. 1 is the structural representation of the utility model vavuum pump external oil mist filter.

Detailed description of the invention:

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment:

As shown in Figure 1, a kind of vavuum pump external oil mist filter of the present utility model, comprise circular filter base 1, at the upper surface of filter base 1, filter core 2 is coaxially installed, filter core 2 is opening down in drum-shaped, the filter housing 3 of a tubular is filled with at the outer coaxial cover of filter core 2, filter base 1 also has the admission line 4 of a L shape and the Oil Guide pipeline 5 of a L shape, the inner port coaxial communication that wherein admission line 4 longitudinal pipe of L shape is corresponding the mesopore of filter core 2, the transverse pipe level of admission line 4 is communicated with on the outer ring surface of filter base 1, one end of a right angle Pneumatic quick connector 8 and external port corresponding to admission line 4 transverse pipe spins, the other end of right angle Pneumatic quick connector 8 is communicated with on the exhaust outlet of vavuum pump by flexible inlet pipe 6, the inner port that wherein Oil Guide pipeline 5 longitudinal pipe of L shape is corresponding is positioned on filter base 1 corresponding between filter core 2 with filter housing 3, the transverse pipe level of Oil Guide pipeline 5 is communicated with on the outer ring surface of filter base 1, and the transverse pipe coaxially relative both sides being positioned at admission line 4 of the transverse pipe of admission line 4 and Oil Guide pipeline 5, to spin one end of another right angle Pneumatic quick connector 8 in the external port that Oil Guide pipeline 5 transverse pipe is corresponding, the other end of this right angle Pneumatic quick connector 8 is by the special air flue of elasticity oil return pipe 7 through pump inside and the discharge chamber UNICOM of vacuum pump stator, wherein flexible inlet pipe 6 and elasticity oil return pipe 7 are PVC transparent sebific duct, check valve structure is provided with in special air flue, when pump brings into operation, pressure now in discharge chamber is higher than atmospheric pressure, at this moment check-valves is closed condition, ensure that oil gas can not recoil air from Oil Guide pipeline 5 by gas circuit, when after a period of time that pump operation is very short, pressure low-pressure atmospheric pressure in discharge chamber, at this moment negative pressure is formed, check-valves conducting, oil strain in filter is directly drawn into discharge chamber by Oil Guide pipeline 5 from gas circuit, then fuel tank internal is drained into, thus do not have long-pending oil spill and go out when ensureing oil mist filter long-play.

Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
