This application relates to the technical field of oil separators, and more particularly to oil separators. [Background technology]

[0002] The existing oil separator includes a cylinder and an intake pipe, with an intake port on the outer wall of the cylinder, the axis of which intersects with the axis of the cylinder, and the fluid passes through the intake pipe and enters the cylinder. After separation inside, the gas flows out through the exhaust pipe, and the oil falls to the bottom of the cylinder and flows out through the oil return pipe at the bottom. The conventional method has poor oil and gas separation effect and is difficult to meet the usage requirements. Summary of the Invention [Problem to be solved by the invention]

[0003] The present application provides an oil separator to solve the problem of poor separation effect of oil separators in the prior art. [Means for solving the problem]

[0004] The present application provides an oil separator, which includes a cylinder having an intake hole in its side wall, the axis of which does not intersect with the axis of the cylinder, and an intake pipe that penetrates the intake hole and communicates with the interior of the cylinder. In addition, an annular flange is further installed around the periphery of the intake hole, and the annular flange is installed inside or outside the cylinder, and the intake pipe is connected to the annular flange, so that the specific position of the flange can be set according to the actual use needs of the device, thereby increasing the applicability of the device. Furthermore, an annular flange is further installed around the periphery of the intake hole, which passes through both sides of the intake hole and the intake pipe is connected to the annular flange, thereby further increasing the contact area between the intake hole and the intake pipe, thereby maximizing the welding strength between the intake hole and the intake pipe and ensuring the stability of the device during operation. Furthermore, the annular flange penetrates both sides of the intake hole. The annular flange has a connecting end and a free end that are oppositely arranged, and the free end of the annular flange protrudes from the outer wall of the cylinder, and the end surface of the free end of the annular flange is flat or arcuate. By configuring the above structure, one end surface of the annular flange is arranged flat, which facilitates the connection between the intake pipe and the intake hole during the installation process, making it easier to weld the intake pipe and the intake hole and improving the installation efficiency of the device. By configuring one end of the annular flange as an arcuate surface, which facilitates the processing of the annular flange, it is advantageous to reduce the production costs of the device. Furthermore, when the free end face of the annular flange is an arcuate surface, the pitch of the arcuate surface is the same as that of the outer wall surface of the cylinder, and the above arrangement ensures that the curvature of the free end of the annular flange in the extension direction is the same as that of the outer wall surface of the cylinder, thus ensuring the consistency of the structure of the entire device. Furthermore, the axis of the annular flange coincides with the axis of the intake hole. This arrangement ensures the conformity of the structures of the annular flange and the intake hole, further ensuring the overall structural strength after the intake hole is welded to the intake pipe. Furthermore, the height of the annular flange is more than 0.5 mm. This structure ensures a sufficient connection area between the annular flange and the intake pipe, and also makes rational use of the space on the outer wall of the cylinder. Furthermore, the oil separator further includes an exhaust pipe, the cylinder has an exhaust hole, the exhaust pipe penetrates the exhaust hole and communicates with the inside of the cylinder, and the outer diameter of the exhaust pipe located inside the cylinder is smaller than the outer diameter of the exhaust pipe located outside the cylinder. Furthermore, the intake pipe and the intake hole are connected by brazing or argon gas arc welding, which further ensures the structural strength after the intake pipe and the intake hole are welded together, ensures the stable operation of the device, and extends the service life of the device. Furthermore, the end face of the intake pipe located inside the cylinder is a slope.

[0005] In this application, the axis of the intake port does not intersect with the axis of the cylinder, which increases the centrifugal effect when the fluid enters the cylinder and further promotes gas-liquid separation of the fluid, improving the separation efficiency and effectiveness of the device. The above structure makes it easier to weld the intake port and the intake pipe, and also increases the connection strength between the intake port and the intake pipe.

[0008] Below, a clear and complete description of the embodiments of the present application will be provided in conjunction with the drawings of the embodiments of the present application. It is clear that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and does not constitute any limitation on the present application and its applications or uses. Any other embodiments that a person skilled in the art can obtain based on the embodiments of the present application without performing any creative work fall within the scope of protection of the present application.

[0009] As shown in Figures 1 and 2, an embodiment of the present invention provides an oil separator, which includes a cylinder 10 and an intake pipe 20. The side wall of the cylinder 10 has an intake hole 11, the axis of which does not intersect with the axis of the cylinder 10, and the intake pipe 20 passes through the intake hole 11 and communicates with the interior of the cylinder 10.

[0010] In the embodiment of the present application, the axis of the intake port 11 does not intersect with the axis of the cylinder 10, which increases the centrifugal effect when the fluid enters the cylinder 10 and further promotes gas-liquid separation of the fluid, improving the separation efficiency and effectiveness of the device. The above structure makes it easy to weld the intake port 11 and the intake pipe 20 together and increases the connection strength between the intake port 11 and the intake pipe 20.

[0011] Specifically, the end face of the intake pipe 20 located inside the cylinder 10 is designed as a slope. In this way, the centrifugal effect of the fluid entering the cylinder 10 can be further enhanced.

[0012] An annular flange 111 is further installed around the periphery of the intake hole 11. The annular flange 111 may be installed inside or outside the cylinder 10, and the intake pipe 20 is connected to the annular flange 111. In this way, the specific position of the flange can be set according to the actual use needs of the device, thereby increasing the applicability of the device. In this embodiment, the annular flange 111 is installed on the outside of the cylinder 10. The annular flange 111 is installed around the periphery of the intake hole 11, so that during installation, the outer wall of the intake pipe 20 contacts the annular flange 111 and one end of the intake pipe 20 communicates with the interior of the cylinder 10, thereby increasing the contact area between the intake pipe 20 and the cylinder 10.

[0013] In another embodiment of the present application, an annular flange 111 passes through both sides of the intake hole 11, and the intake pipe 20 is connected to the annular flange 111. By further increasing the contact area between the intake hole 11 and the intake pipe 20 in this way, the welding strength between the intake hole 11 and the intake pipe 20 can be further increased, ensuring the stability of the device during operation.

[0014] The end face of the annular flange 111 may be a flat surface, an arcuate surface, or an inclined surface, as long as it can easily connect the intake pipe 20 and the intake hole 11.

[0015] 4, the annular flange 111 has a connecting end and a free end 1112 that are oppositely disposed, and the free end 1112 of the annular flange 111 protrudes from the outer wall of the cylinder 10, and the end surface of the free end 1112 of the annular flange 111 is flat. By providing the above structure, one end surface of the annular flange 111 is flat, which makes it easier for the intake pipe 20 to enter the intake hole 11 during the installation process, facilitating welding of the intake pipe 20 and the intake hole 11 and improving the installation efficiency of the device.

[0016] 5, the annular flange 111 has a connecting end and a free end 1112 arranged opposite each other, the free end 1112 of the annular flange 111 protruding from the outer wall of the cylinder 10, and the end face of the free end 1112 of the annular flange 111 being an arcuate surface. The above-mentioned installation structure is simple, and one end of the annular flange 111 is arranged on an arcuate surface, which makes it easy to process the annular flange 111, which is advantageous in reducing the production costs of the device.

[0017] Specifically, when the end face of the free end 1112 of the annular flange 111 is an arcuate surface, the arcuate surface has the same pitch as the outer wall surface of the cylinder 10. This arrangement ensures that the curvature of the free end 1112 of the annular flange 111 in the extension direction is the same as that of the outer wall of the cylinder 10, thereby ensuring the conformity of the structure of the entire device and facilitating processing, thereby reducing processing costs.

[0018] Furthermore, the axis of the annular flange 111 overlaps with the axis of the intake hole 11. The above installation can ensure the conformity of the structures of the annular flange 111 and the intake hole 11, which further ensures the strength of the entire structure after the intake hole 11 is welded to the intake pipe 20, and this structure makes it easy to insert the intake pipe 20 into the intake hole 11.

[0019] Specifically, the height of the annular flange 111 is 0.5 mm or more. This structure ensures a sufficient contact area between the annular flange 111 and the intake pipe 20, and also makes reasonable use of the space on the inner and outer walls of the cylinder 10. The height of the annular flange 111 may be set to 0.5 mm, 1 mm, 1.5 mm, etc.

[0020] Furthermore, the oil separator is made of stainless steel. The structure of this material is easy to process, reducing the production cost of the device and efficiently reducing the weight of the device, ensuring a lightweight device. In other embodiments of the present application, the oil separator may be made of other metallic materials, and different materials can be selected depending on the environment in which the device is used, thereby increasing the applicability of the device.

[0021] Furthermore, the intake pipe 20 and the intake hole 11 are connected by brazing or argon gas arc welding. The above welding method further ensures the structural strength of the intake pipe 20 and the intake hole 11 after welding, ensures the operational stability of the device, and extends the service life of the device. In the gas embodiment of the present application, the intake pipe 20 and the intake hole 11 may also be connected and fixed by other methods as long as the operational performance of the device after the intake pipe 20 and the intake hole 11 are ensured.

[0022] The oil separator further includes an exhaust pipe 30, the outer diameter of which is located inside the cylinder 10 and is smaller than the outer diameter of which is located outside the cylinder 10, thereby restricting the connection depth of the exhaust pipe 30, and a knurl is provided at the welding point between the exhaust pipe 30 and the cylinder 10, thereby ensuring sufficient solder at the welding point and ensuring structural strength after welding.

[0023] As shown in FIG. 3, another embodiment of the present invention provides an oil separator, which differs from the above embodiment in that the annular flange 111 in the present invention is installed inside the cylinder 10.

[0024] In this application, the axis of the intake hole 11 does not intersect with the axis of the cylinder 10, which enhances the centrifugal effect when fluid enters the cylinder 10 and further promotes gas-liquid separation of the fluid, thereby improving the separation efficiency and effectiveness of the device. An annular flange 111 is installed around the periphery of the intake hole 11. During installation, the outer wall of the intake pipe 20 contacts the annular flange 111, and one end of the intake pipe 20 communicates with the interior of the cylinder 10. This increases the contact area between the intake pipe 20 and the cylinder 10. This structure facilitates welding the intake hole 11 and the intake pipe 20 and increases the connection strength between the intake hole 11 and the intake pipe 20. Furthermore, the annular flange 111 can be installed inside or outside the cylinder 10. The specific location of the flange can be adjusted according to the actual usage needs of the device, thereby expanding the applicability of the device.
