Description

Oil-gas separator assembly Technical Field The utility model relates to the technical field of vacuum pump equipment, in particular to an oil-gas separator assembly. Background The oil-gas separator is mainly applied to a vacuum system, and can be used for separating oil from gas of an oil-gas mixture discharged from the vacuum system. The oil-gas separator of the vacuum pump disclosed in the Chinese patent No. 221824067U has the advantages that the inner barrel of the filtering component in the barrel adopts an integral forming non-detachable mode with the outer barrel, the structural mode is inconvenient for replacing an oil core (an oil-gas separation filter element) and cleaning and maintaining the barrel body, moreover, the phenomenon that oil stains are generated on the outer wall of the oil core in the use process can occur, oil is accumulated on the bottom plate of the inner barrel, the problems of easy occurrence of oil stains or coking and the like cannot be eliminated in time, the more the accumulation affects the filtering effect, and the oil-gas content in the exhaust gas is not up to standard. In addition, when the oil-gas mixture enters the outer barrel from the tangential direction, large oil drops are separated by high-speed rotation and then directly enter the oil core, so that the impact on the oil core is large, and the service life of the oil core is short. Disclosure of utility model The utility model aims to solve the problems and provide an oil-gas separator assembly. The utility model discloses an oil-gas separator assembly, which comprises an outer separator barrel, a flange barrel cover and an oil-gas filtering component arranged in the outer separator barrel, wherein the side wall of the outer separator barrel is connected with an oil-gas mixture inlet pipe, the flange barrel cover is connected with an exhaust pipe, the oil-gas filtering component comprises an inner barrel with a flange at a barrel opening, the inner barrel is connected with the outer separator barrel and the flange barrel cover through the flange, a plurality of oil core mounting seats for mounting oil cores are arranged on the bottom plate of the inner barrel and are respectively provided with the oil cores, the inlets of the oil cores are downwards communicated with the inner part of the outer separator barrel, a connecting through hole is further arranged at the edge of the bottom plate of the inner barrel, a sunk oil gathering pipe is connected at the connecting through hole, an oil absorbing pipe is further arranged on the flange barrel cover in a penetrating mode, the inner end of the oil absorbing pipe stretches into the bottom of the oil gathering pipe, and the outer end of the oil absorbing pipe is sequentially connected with a first one-way valve and an oil returning pipe so as to be connected with a vacuum pump host through the oil returning pipe. A baffle plate is also connected below the bottom plate of the inner barrel, and a plurality of through holes are arranged on the baffle plate. The exhaust pipe of the flange barrel cover is vertically upwards and sequentially connected with an elbow pipe and a big tee joint, an outlet of the elbow pipe is connected with the big tee joint along the horizontal direction, an exhaust port of the three tee joints is upwards, a lower pipe orifice coaxially arranged with the exhaust port is connected with a lower cover, a middle opening of the lower cover is connected with a second one-way valve, and the second one-way valve is connected with an oil return pipe and the first one-way valve through a small tee joint. According to the utility model, the inner barrel of the oil-gas filtering component and the outer barrel of the separator adopt a split detachable structure, and the oil-gas filtering component can be integrally detached to the outside of the assembly for replacement or maintenance cleaning and other operations, so that the convenience and the cleaning thoroughness are improved; the oil gathering pipe, the oil suction pipe and the oil return pipe are arranged, so that the oil stain attached to the outer wall of the oil core can be sucked away without additional power, the problems that oil dirt, coking and the like are formed due to the fact that the interior of the inner barrel cannot discharge oil can be avoided, and the problems of high later maintenance difficulty, high cost and the like are avoided; therefore, the oil-gas separator assembly has the advantages of convenience in maintenance, convenience in cleaning, good oil-gas separation effect, long service life, low maintenance cost and the like.
