Description

A kind of deaerator of vacuum pump

Technical field

The utility model relates to the deaerator of a kind of deaerator, particularly a kind of vacuum pump.

Background technique

Rotary sheet type oil seal vacuum pump work the time can enter certain amount of vacuum pump oil, pumping fluid mixes the back with pumped gas and discharges at a high speed with pumped gas in pump chamber, do not separate reuse and directly drain into outside the pump if will not discharge oil in the gas, will cause environmental pollution, the wasting of resources.Need gas separation is wherein come out for this reason, present a kind of deaerator of industrial extensive employing, it comprises a body and a "T"-shaped porous filtering spool, the body lower end is provided with an import, and it links to each other with fuel tank by pipeline, and a blind hole is set in the middle of the "T"-shaped porous filtering spool head, the blind hole bottom is provided with a plurality of exhaust ports that are communicated with it, the spool head gos deep into the body import during installation, and afterbody supports the location by a pole, with the slip working stroke of control spool.When not having gas in the fuel tank, spool is positioned at bottom under the deadweight effect, exhaust port is positioned at body import not conducting of the inside, the running noise of having avoided pump unofficial biography in the fuel tank, and when containing gas in the fuel tank, the high pressure oil-containing gases will back down spool, makes the exhaust port on the spool be in opening state, make gas enter the oil separator body interior and wherein oil is blocked, and then reach the purpose of Oil-gas Separation.The use of advancing is for many years found, only relies on the first separation process of filtering spool, and the gas of discharge still has higher oil content, thereby causes the unnecessary wasting of resources, can pollute the pump housing simultaneously, brings very big inconvenience to the user.

The model utility content

The purpose of this utility model is to provide a kind of deaerator of vacuum pump, and it is by a kind of secondary separation structure, and separating oil and gas have characteristics simple in structure, energy-conserving and environment-protective more up hill and dale.

For achieving the above object, the utility model adopts following technological scheme:

A kind of deaerator of vacuum pump, include housing and top cover, its middle shell lower end offers import, top cover is provided with the air outlet, described housing import is provided with one and filters spool, it is characterized in that: described housing inner chamber the inside is provided with two and separates catch, the outer edge surface of catch and housing inner chamber are equipped with, the bottom of catch is provided with a plurality of supporting foots, the supporting foot and the housing bottom of first catch offset, second catch is by supporting foot and the stack setting separated by a distance of first catch, and its rear end holds with top cover mutually by a spring.

Described washer is down beveled structure, and the edge height is middle low, at washer center lowest part one oil guiding hole is set simultaneously, and the catch edge is provided with two or more equally distributed passages.

Described two washers are provided with the angular orientation stack that the passage that is provided with on it staggers mutually.

The utility model utilizes hydrocarbon containing fluid to enter in the separator, through filtering spool and two secondary separations that separate catch, thoroughly separates oil is gentle.When containing gas in the fuel tank, the high pressure oil-containing gases will back down spool, makes the exhaust port on the spool be in opening state, makes gas enter the oil separator body interior and wherein part oil is blocked, and realizes Oil-gas Separation for the first time under the deadweight effect.Hydrocarbon containing fluid after separating for the first time is by entering disengagement chamber, clash into first and separate catch, the part gas mixture directly continues to rise from the passage at catch edge, the mixture of part clashes into the catch lower surface in addition, roll air-flow and scattering to the left and right of formation, when the air-flow that rolls walks to passage, under driving, upward flow continues to rise; The hydrocarbon containing fluid bump stack of rising from first catch passage is arranged on second catch on first catch, form once more roll air-flow and about scatter; Utilize oil different with the proportion of gas, hydrocarbon containing fluid two catch of bump and produce centrifugal force when rolling add the deadweight that oils and catch and housing internal chamber wall the adhesive attraction of oil are formed the Oil-gas Separation second time.Oil accumulation after the separation falls on the umbrella cover to separating catch, falls back in the fuel tank under the oil guiding hole of catch center lowest part.The process of secondary separation has strengthened the centrifugal force of gas mixture greatly, makes that the oil in the mixture fully separates, and realize more effective recovery of oil, and the design of two catch can be played more effective sound deadening.

Embodiment

As Fig. 1, shown in 2 and 3, a kind of deaerator of vacuum pump, comprise housing 1 and top cover 2, housing 1 and top cover 2 are connected by worm structure, top cover 2 places are with seal ring 22 to increase the seal degree that connects, housing 1 lower end offers import 11, import 11 is provided with one and filters spool 4, housing 1 inner chamber the inside is provided with separates catch 31 and separates catch 32, the outer edge surface of catch 31 and catch 32 and housing 1 inner chamber are equipped with, the edge of two catch is provided with passage 311 and passage 321, the bottom is provided with a plurality of supporting foots, the supporting foot 323 and the housing bottom of catch 32 offset, and catch 31 is by supporting foot 313 and the stack setting separated by a distance of first catch, and its rear end holds with top cover 2 mutually by a spring 5.Two catch upper surfaces are provided with a plurality of projections, and the projection 324 on the catch 32 is provided with the supporting foot 313 of the catch 31 on it in order to the location, the projection on the catch 31 in order to the location be provided with its on spring 5.

When containing gas in the vacuum pump fuel tank, the high pressure oil-containing gases will back down and filter spool 4, make the exhaust port 41 on the spool 4 be in opening state, make oil-containing gases enter oil separator housing 1 inner chamber and wherein part oil is blocked, under the deadweight effect, realize Oil-gas Separation for the first time.Hydrocarbon containing fluid after separating for the first time is by after entering housing 1 inner chamber, bump separates catch 32, the part gas mixture directly continues to rise from the passage 321 at catch 32 edges, the mixture of part clashes into catch 32 lower surfaces in addition, roll air-flow and scattering to the left and right of formation, when the air-flow that rolls walks to passage 321, under driving, upward flow continues to rise; The hydrocarbon containing fluid bump stack of rising from catch 32 passages 321 is arranged on the catch 31 on the catch 32, form once more roll air-flow and about scatter; Utilize oil different with the proportion of gas, the centrifugal force that hydrocarbon containing fluid produces when rolling at bump catch 31 and catch 32 adds the deadweight that oils and two and separates catch and housing 1 internal chamber wall the adhesive attraction of oil is formed the Oil-gas Separation second time.Gas after the separation goes out to discharge from the outlet 21 of top cover, and the oil accumulation after separating separates catch two and falls on the umbrella cover, falls back in the fuel tank for 312 times through the oil guiding hole 322 and the oil guiding hole of catch center lowest part.

The utility model carries out the secondary separation process to gas mixture, makes both separation more thorough, can realize effective recovery of oil, reduces the unnecessary wasting of resources, and the design of two catch in the vacuum pump fuel tank more can be played significant sound-deadening and noise-reducing functional effect.
