Technical Field

[0001] This utility model belongs to the field of engine exhaust gas filtration devices, and specifically relates to an independent filter element oil-gas separator. Background Technology

[0002] Most oil-gas separators on the market are integrated into the engine block, valve cover, or other modules. This results in only one type of oil-gas separator per module. When the direction of the oil-gas separator's outlet needs to be adjusted, the entire oil-gas separator containing other modules needs to be redesigned, leading to high design and production costs and a lack of product diversity. Summary of the Invention

[0003] The purpose of this invention is to provide an independent filter element oil-gas separator that adopts an independent installation method and allows for the selection of different air outlet angles.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an independent filter element oil-gas separator, comprising:

[0005] The casing has an open upper end with an air inlet and an oil return outlet.

[0006] The filter element is installed inside the housing;

[0007] The top cover is installed on the upper end of the housing and has an air outlet. The filter element divides the internal space of the housing into a pre-filter space that communicates with the air inlet and a post-filter space that communicates with the air outlet.

[0008] The outer circumferential surface of the housing is provided with a fixed connecting plate integrally formed with the housing, and the separator further includes a first bolt assembly for fixing the fixed connecting plate; the housing is fixedly connected to the housing of the engine through the first bolt assembly.

[0009] In another embodiment, the upper surface of the housing is provided with a plurality of limiting grooves arranged in a ring array, and the outer peripheral surface of the top cover is provided with limiting blocks that match the limiting grooves. The angle of the air outlet can be adjusted by engaging the limiting blocks with different limiting grooves, and the rotational freedom of the top cover is restricted by the limiting grooves.

[0010] In another embodiment, a positioning seat is formed on the outer peripheral surface of the housing, and the oil-gas separator includes a clamping plate detachably connected to the positioning seat. An annular first convex ring is formed on the outer peripheral surface of the top cover. When the top cover is installed on the housing and the clamping plate is installed on the positioning seat, the lower end face of the clamping plate abuts against the upper end face of the first convex ring, thereby restricting the degree of freedom of the top cover in the vertical direction.

[0011] In another embodiment, an annular mounting platform is formed on the inner side of the upper end face of the housing, which is lower than the upper end face of the housing. When the upper cover is mounted on the housing and the clamping plate is mounted on the positioning seat, the first convex ring presses against the annular mounting platform, and the lower end face of the clamping plate abuts against the upper end face of the first convex ring, thereby restricting the degree of freedom of the upper cover in the vertical direction.

[0012] In another embodiment, the upper end face of the positioning seat and the upper end face of the first convex ring are flush with the upper end face of the housing; when the clamping plate is fixed to the positioning seat by the second bolt, its lower end face presses against the upper end face of the positioning seat, the upper end face of the first convex ring, and the upper end face of the housing.

[0013] In another embodiment, the fixed connecting plate is arranged along the axis perpendicular to the housing, and connecting holes are provided at its left and right ends respectively; the housing is fixedly connected to the engine housing by a first bolt assembly provided in the connecting holes.

[0014] In another embodiment, a reinforcing rib is provided between the fixed connecting plate and the outer peripheral surface of the housing.

[0015] In another embodiment, the bottom of the housing is provided with a filter element mounting base, the filter element is inserted into the filter element mounting base, the middle part of the filter element mounting base is connected to the middle part of the filter element and connected to the oil return port; when the oil-gas mixture enters the air inlet, it is filtered by the filter element, the oil flows from the middle part of the filter element to the oil return port, and the filtered gas flows upward into the upper cover and flows out from the air outlet.

[0016] In another embodiment, the upper cover is provided with an air outlet pipe, the inlet of the air outlet pipe faces upward, and its outlet is the air outlet.

[0017] In another embodiment, the upper cover is provided with a valve plate located above the inlet of the air outlet pipe, and a tension spring that always covers the inlet of the air outlet pipe. When the air pressure in the filtered space exceeds a threshold, the valve plate is lifted and exhaust is performed.

[0018] Due to the application of the above technical solutions, this utility model has the following advantages compared with the prior art: This utility model achieves detachable installation with other modules through a fixed connecting plate, which improves the applicability of the oil-gas separator. Furthermore, by using different installation angles of the top cover and the housing, different outlet angles can be selected, which can meet the diverse needs of customers and save on design and mold production costs.
