Embodiment
Fig. 1 is the sectional view of gas and oil separating plant described in the utility model embodiment, and as shown in Figure 1, a kind of gas and oil separating plant that the present embodiment provides, comprises housing 2, filter core 3, cooling tube 1 and top cover 4; In housing 2, be fixed with filter core 3, housing 2 inner spaces are divided into the first chamber 8 and the second chamber 9 by filter core 3, the top of cooling tube 1 is stretched into housing 2 inside and is carried oil gas to the first chamber 8, is formed for the second chamber 9 and the outside gas channel being communicated with between top cover 4 and housing 2.。
In the present embodiment, oil gas 5 refers to the mixture that lubricant oil gasifies afterwards under the high temperature action of transmission part and air forms.
Fig. 2 is the oil gas flow graph of gas and oil separating plant described in the utility model embodiment, as shown in Figure 2, the bottom of cooling tube 1 is installed on the vent of speed reducer 6, the parts such as the gear of speed reducer 6 are because high-speed drive produces high temperature, this high temperature gasifies to form oil gas 5 by the lubricant oil in speed reducer 6 and discharges from vent, enter thus in the cooling tube 1 being arranged on vent, the lubricant oil of gaseous state is in the time running into the colder tube wall of cooling tube 1, part heat release liquefaction forms lubricated oil droplet 7 and adheres on the inwall of cooling tube 1, under the effect of gravity, again flow back into speed reducer 6 inside, reduce the loss of lubricant oil.
The lubricated oil gas 5 of not liquefaction part enters housing 2 inside through cooling tube 1, housing 2 inner spaces will be divided into the second chamber 9 of oil gas after the first chamber 8 of oil gas before accommodating filtration and accommodating filtration by filter core 3, oil gas 5 enters the first chamber 8 through cooling tube 1, the gaseous state lubricant oil not wherein being liquefied is filtered by filter core 3 while passing filter core 3, remainder after oil gas 5 is filtered by filter core 3 enters the second chamber 9, be discharged in atmosphere by the gas channel between top cover 4 and housing 2, oil gas 5 after being filtered by filter core 3 not containing gaseous state lubricant oil, does not pollute atmosphere substantially.
Thus, the utility model is made the lubricant oil cooling liquid of part gaseous state and is refluxed by cooling tube, has reduced the loss of lubricant oil, simultaneously, the lubricant oil not being liquefied, by filter element filtering, makes substantially not contain lubricant oil discharged to the tail gas of working site, has cleaned on-the-spot air.
Fig. 3 is the structural representation of speed reducer described in the utility model embodiment, as shown in Figure 3, because the bottom of cooling tube 1 is connected on the vent of speed reducer 6, therefore the large portion of cooling tube 1 or entirety are positioned at the outside of speed reducer 6, its temperature is consistent with ambient temperature, therefore can in the time running into cooling tube 1, liquefy through the lubricant oil of high-temperature gasification.Cooling tube 1 is longer, when oil gas 5 process cooling tube 1, the liquefaction ratio of gaseous state lubricant oil is just larger, cooling effect is just better, but simultaneously, affect gas and oil separating plant is assembled to the global stability after speed reducer to long cooling tube 1 on the one hand, and cooling tube 1 is long more on the other hand only itself also can not be completely by the lubricant oil liquefaction of gasification.Therefore, the length of cooling tube 1 should be according to the kind of speed reducer 6 and power determination, ensures its length most of gasification lubricant oil that can liquefy.Cooling tube 1 should be selected the tubing of perfect heat-dissipating, and with the lubricant oil of the gaseous state that farthest liquefies, this example is selected Coating Steel Pipe or copper pipe.
Filter core 3 in the present embodiment, for practical lubricating oil types, selects can filter in prior art the filter core 3 of associated lubrication oil, and the present embodiment is not construed as limiting this.Filter core 3 in the present embodiment, selects filter core 3 cylindraceous in profile, filter core 3 is arranged at housing 2 inside.The top of filter core 3 contacts with the bottom interior surface of housing 2 with the internal surface of top cover 4 respectively with bottom.
Further, for fixing filter core 3, in the present embodiment, the interior part of housing 2 is stretched into in the top of cooling tube 1, between this part and the madial wall of housing 2, form the first circular groove, the first circular groove matches with the bottom of filter core 3, so that the bottom of filter core 3 is just fixed in the first circular groove.Same, columniform boss 41 is set in the top inner wall of top cover 4, between boss 41 and the madial wall of housing 2, form the second circular groove, the second circular groove matches with the top of filter core 3, so that the top of filter core 3 is just fixed in the second circular groove.The degree of depth of the first circular groove and the second circular groove is preferably 5mm.
The gas and oil separating plant that the present embodiment provides, further, at top and the bottom mounting circular ring shape Sealing 31 of filter core 3, Sealing 31 preferred rubber pads, rubber sheet gasket is padded between filter core 3 and housing 2 and top cover 4.
Obvious, filter core 3 is except above-mentioned preferred cylindric embodiment, and other filter core, can be divided into housing 2 inside all can of accommodating the first chamber that does not filter oil gas and accommodating second two parts of chamber of having filtered oil gas.
Fig. 4 is the worm's eye view of top cover described in the utility model embodiment; Fig. 5 is the sectional view of top cover described in the utility model embodiment, referring to Fig. 4 and Fig. 5, top cover 4 is spirally connected with housing 2, is interval with multiple vertical hollow ridges 42 on top cover 4, gap between hollow ridge 42 and housing 2 is gas channel 43, discharges for the oil gas after filtering.The hollow ridge 42 of interval design had both allowed top cover complete being spirally connected of housing 2, was convenient to installation and removal, had met again the discharge demand of oil gas.
As shown in Figure 3, the utility model embodiment also provides a kind of speed reducer 6, and the bottom vertical of the cooling tube 1 in above-mentioned oil gas 5 segregating units is connected on the vent of speed reducer 6, and in speed reducer 6, the lubricant oil of gasification is directly entered gas and oil separating plant 5.
The speed reducer that the utility model provides, the oil gas that speed reducer is discharged enters cooling tube, cooling tube makes the lubricant oil cooling liquid of part gaseous state and is back in speed reducer, reduce the loss of lubricant oil, simultaneously, the lubricant oil not being liquefied, by filter element filtering, makes substantially not contain lubricant oil discharged to the tail gas of speed reducer working site, has cleaned on-the-spot air.
Obviously, except speed reducer, numerous equipment of mechanical transmission fields all need oil lubrication, in the time of high-speed drive, all there is the loss problem causing because of lubricant oil gasification in these equipment, the gas and oil separating plant that the utility model provides all can use on the said equipment.
Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or some or all of technical characteristics is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment's technological scheme of the utility model.
